Ernie Andrade: All the Bright Moves

By James Florence, Diamond Certified Program Reporter

SANTA ROSA — A third-generation plumbing and HVAC professional, Ernie Ongaro reflects on the longstanding legacy of his family’s business. “My grandfather started Ongaro & Sons in 1932,” he recounts. “All three of his sons followed him in the business, and it was the same way with me, my brother and our two cousins. Now, with my son and nephew joining the company, we’re heading toward our fourth generation of family ownership.”

As president of Ongaro & Sons, Ernie says his favorite part of his job is staying on the cutting edge of his professional field. “It’s really important for us to keep up-to-date with our industry, so we’re always looking for the latest equipment and methods of doing things. I also enjoy watching our technicians start from scratch and progress in their careers. It’s kind of exciting to see the growth of your employees—it gives you a sense of pride.”

A longtime resident of Santa Rosa (where he lives with his wife, Debbie), Ernie has fond memories of growing up in rural Sonoma County. “In addition to running the company, my dad was sort of a gentleman farmer and raised cattle. Growing up on a ranch was fun, even though I used to have to milk the cows twice a day. I still love living in Sonoma County—it’s a beautiful place.”

Outside of work, Ernie engages in a variety of active pastimes, from traveling to restoring vintage cars. “My wife and I love to travel, both within the United States and abroad,” he says. “I also enjoy restoring vintage vehicles. I have a 1942 Willys Jeep that I drive in local parades, and I also restored a 1932 Chevy pickup that I modeled after my grandfather’s first plumbing truck.” Additionally, Ernie enjoys reading and spending time with his family, including his grown children, Ernest and Allison.

In regard to his professional career, Ernie says the family dynamic has always played a vital role at Ongaro & Sons. “Being a fourth-generation business, family is very important to us, and that informs the way we treat our employees and customers. We treat our employees like part of our family and try to be sensitive to their needs. Likewise, we take care of our customers and always follow up with them to make sure they’re 100 percent satisfied.”

When asked the first thing he’d do if he were to retire tomorrow, Ernie says he’d hit the open road. “I would probably take a road trip and visit some places in the U.S. that I haven’t seen yet. Actually, I recently finished a book about Lewis and Clark, and I think it would be neat to take a trip that follows the path they traveled.”

Ask Me Anything!

Q: What kinds of books do you like?
A: I’m a history buff, so I love to read biographies and historical accounts.

Q: What’s your favorite kind of food?
A: Italian.

Q: Do you collect anything?
A: Vintage cars, trucks and military vehicles.

Q: Are you an early bird or a night owl?
A: Definitely an early bird.

What To Ask In Person
Questions to Ask Good Commercial Office Cleaning Services in Santa Clara County

Now that you’ve talked with some janitorial firms on the phone, you will probably have narrowed down your list to a few stand-out office cleaning companies.

This is the time to invite a few of the best commercial cleaning firms to see your office—whether it’s in San Jose, Sunnyvale, Milpitas, Mountain View, Santa Clara, Campbell or another area—and bid to be your janitorial service provider.

The questions below are some you should ask when meeting with the Santa Clara County janitorial company representative. Take notes of their answers, their tone and any additional information you may want to incorporate into your decision-making process.

  • How does your janitorial company handle complaints or questions from customers?(Remember: local branches of national office cleaning chains may not be able to make decisions at the local level, so you may have to wait for a reply from the national office if you have a complaint or problem.)
  • Will your office cleaning company provide material safety data sheets (MSDS) information for the cleaning products they use for office cleaning? (You are required by OSHA to have MSDS information for all chemicals and cleaning products used in and around your commercial office facilities.)
  • Will your Santa Clara County custodial services use green commercial cleaning products, unscented office cleaning products or other eco-friendly janitorial supplies upon request?
  • Will you accompany me on a walk-through to determine the cost of our janitorial cleaning services?
  • Or do you have a set charge based on office size and number of visits?
  • Will you provide emergency janitorial cleaning services or accommodate us for office cleaning services that are in addition to our regular office cleaning schedule?
  • Will our company have to sign a long-term contract for janitorial services? Or do you offer monthly or short-term contracts for office cleaning?
  • Do you have references I can from companies similar to mine in size and scope?(Keep in mind that if you’re hiring a local janitorial company that’s part of a janitorial franchise, the company may give you references that other franchise companies have worked for. Be sure to ask specifically for the names of references that Santa Clara County office cleaning service has done work for.)

  • What To Ask References
    Ask References of Santa Clara County Commercial Janitorial Companies

    It’s best to choose a Diamond Certified janitorial firm in Santa Clara County because all certified office cleaning companies have passed an in-depth ratings process that most others can’t pass.

    If you want quality from a custodian firm in Santa Clara County and the greater Bay Area, you will have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews, because all research is performed in live telephone interviews of actual customers.

    If you do call references on your own, specifically ask for a list of the company’s 10 most recent/current customers from your area of Santa Clara County.

    You should also ask for long-time clients and others who receive the same type of services (office building cleaning, medical building cleaning, school cleaning, office park cleaning, dayporter services, etc.) that you are considering. This will help avoid the custodial services giving you the names of only customers they know were satisfied.

    Some questions you may want to ask local  janitors include the following:

    • Are you satisfied with the office cleaning services from _(janitorial company name)_?
    • How long have you been using this Santa Clara County janitorial service?
    • What do you like best about this commercial cleaning company? What is your least favorite part about this custodial cleaning firm?
    • What was the type and scope of cleaning they did for you (green janitorial services, commercial janitorial cleaning, industrial janitorial cleaning, small business custodial services, office park cleaning, dayporter services, weekly janitorial cleaning, janitorial product supply, emergency janitorial services, etc.)?
    • Were the janitorial cleaning service staff reliable and personable?
    • Did the custodial service company representative explain to you the status of the work or any problems with the janitorial services?
    • Did they complete the work on time?
    • Were there unexpected costs associated with the commercial janitorial services? If so, what were they for and were they avoidable?
    • Did the Santa Clara County janitorial service business charge extra to travel to your office if it’s located live in a smaller town such as Permanente, Redwood Estates, Saratoga, San Martin, Holy City or Monte Sereno?
    • Would you/have you recommended this janitorial services company to other business owners?

  • Review Your Options
    Hire a Good Janitorial Company in Santa Clara County

    Now that you’ve interviewed local commercial janitorial firms and talked to current customers of custodial services in Santa Clara County, you should be able to select a local business cleaning janitorial company that meets your needs in terms of types of janitorial services, professional attributes and reliability.

  • How To Work With
    Be the Kind of Client Janitorial Services Want to Work For

    When hiring a Santa Clara County commercial cleaning company, it may be hard to remember that many local commercial cleaning companies also have high standards for the type of customers for whom they provide office cleaning. Their time and resources are often limited to a certain number of customers, so they can be choosy about with whom they do business.

    How can you encourage local janitorial services to choose to work for you:

    • Show that you are looking for custodial services that offer good value, not just cheap janitorial services. Many people start their discussion with janitorial contractors by asking about price. However, you can show your interest in quality office cleaning services by asking questions about janitorial supplies, cleaning methods, availability, experience and overall value rather than price alone.
    • Be upfront with the janitorial companies if you’re accepting multiple bids for commercial cleaning services. But only shop among local janitorial companies that offer quality work and don’t seek more than three or five bids. Canvassing dozens of companies shows that you’re only looking for cheap janitorial services, and office cleaning companies that provide the best quality work may not be able to compete with low-cost janitorial services that don’t provide insurance and fair wages to their employees.
    • Tell your janitorial firm exactly what commercial cleaning services you require, how often you expect them and any specific requests or expectations that you have. This will allow them to give you the most accurate bids and gives them insight into exactly what you want. If they can’t provide what you need or want, it’s better to find out before you’ve wasted time thoroughly interviewing a janitorial service in Santa Clara County that can’t meet your needs.
    • Interview and choose among local janitorial cleaning companies in Santa Clara County and the local area. Most custodial companies prefer to work within a smaller radius, as this allows them to provide faster service and more reliable office cleaning. It can also mean they’ll be able to get to you in a hurry if you require emergency office cleaning or unscheduled janitorial services.

    Sign a Contract for Office Cleaning Services in Santa Clara County
    Once you’ve found the janitorial contractor that best fits your needs, make it official by signing a contract for regular office cleaning services.

    This contract should include specific details about the type and scope of office cleaning required, what janitorial supplies and office cleaning products are to be used, payment terms, frequency of office cleaning, any guarantees on the work and other specific items you and the janitorial company representative agreed upon.

    This contract should protect you and your Santa Clara County janitor company, and it should equally represent both of your interests. Contracts are legally binding and for this reason, you should completely read and understand all of the information in the contract. Never sign a blank or incomplete contract, or one that you don’t fully understand.

    Feel free to write in any verbal agreements or special requests you and your janitorial service provider agreed upon. This can include specific expectations, cleaning instructions and other items you wish to make legally binding.

    Simplify the Office Cleaning Work
    Your janitorial company should be able to meet and exceed the expectations and cleaning service directions you’ve agreed upon in the contract. However, there are a few things you can do to make their job easier and get better results.

    Provide easy access to the rooms and office buildings to be cleaned. If the office cleaning takes place after business hours, make sure the janitorial office cleaning company has keys, entrance codes, pass cards or other items that ensure them access to the space to be cleaned. They can waste valuable time and can even miss cleaning appointments if they’re unable to gain entrance to the building. If the business cleaning takes place during office hours, make sure that the janitorial staff has clear access to the rooms in which they need to clean. Keep staff, customers and others out of the rooms to be cleaned, or give them a warning that the janitorial staff will be arriving. This can cut down on the time the office cleaning staff takes to clean the building (and therefore the cost of janitorial services) and may result in cleaner facilities.
    Keep up your end of the contract. You expect your Santa Clara County janitorial company to provide the services they’ve promised, so be sure to hold up your end of the bargain. Provide any janitorial cleaning products promised in the contract, keep to the schedule you’ve agreed upon, and don’t expect the janitorial cleaning company to be unrealistically flexible to frequent and sudden changes. If the terms of your contract change or you need additional or fewer services, give the appropriate amount of warning time before the changes take effect.

    Leave written instructions for jobs not on the regular janitorial contract. If you require additional cleaning services (such as refrigerator cleaning, office kitchen cleaning, carpet stain removal, annual deep cleaning services, etc.) or have special requests, place a call to the Santa Clara County janitorial company and leave written instructions. This will eliminate questions and will ensure you and your janitorial service providers are on the same page when it comes to commercial office cleaning services required.

    Let the Santa Clara County janitors know in advance if the job or timeframe changes. Meetings run late, special work sessions may be scheduled, office shut-downs over the holidays, added shifts, new employees, changes to office space or office configuration, office remodeling and other factors can create confusion if your janitorial cleaning service hasn’t been warned. Be sure to give an appropriate amount of warning if procedures change. This can even include needing more or fewer janitorial cleaning visits or if your office hours change.

    Give your commercial cleaning providers a phone number where they can reach the office building owner or company representative. Your commercial cleaning company should always be able to reach a company representative in case of emergency, such as being locked out or a problem with the office building. Give a janitorial firm representative phone numbers and emergency contacts they’ll need if there’s ever a problem after-hours.

    Ask what you can do to ease their job. This may including having storage space available for janitorial supplies, making amendments to the contract if additional work is required, leaving certain rooms unlocked, providing extra keys or different access, etc. Ask your custodial firm what you can do to make their job go faster, and keep the lines of communication open so they feel free to suggest items that can save them time and can save you money or get you better office cleaning services.

  • Be a Good Customer
    Be a Good Janitorial Customer for the Best Results

    It's the responsibility of the Santa Clara County janitorial firm you’ve hired to clean your facility using the best possible workplace cleaning methods and janitorial supplies. But you play a big part in the long-term success of your contract for commercial office cleaning, too.

    Here are a few simple steps you can take to be a good customer when hiring and working with local janitorial companies in Santa Clara County:

    • Be clear and upfront with the janitorial company representatives. Let them know what you want from your office cleaning services and specific ways they can satisfy your expectations.
    • Remember, a friendly smile goes a long way.
    • Before you hire a Santa Clara County janitorial company, restate your expectations and goals, and reiterate your understanding of the commercial cleaning agreement. Most problems with local custodial firms occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
    • Be sure your janitorial service representative has a phone number at which they can reach you at all times, including when your business is closed. Most office cleaning services take place after business hours, and you will want your business cleaning custodians to be able to reach you if there is an emergency, if they can’t get into the building, or if there are any problems in your office.
    • Return calls promptly when your janitorial contractor contacts you.
    • Pay for the janitorial work promptly.

    Why would you want to be a good customer?

    Santa Clara County janitorial service companies, including those in the larger cities of San Jose, Palo Alto, Cupertino, Santa Clara, Milpitas, Gilroy, Campbell, Morgan Hill, Mountain View and Sunnyvale appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship.

    Read moreRead less
Check The Work
Review the Completed Office Cleaning Services

You should take the time to check the janitorial company’s work the first time they clean your office building. This will enable you to catch any potential problems and make adjustments up front. It will also show them that you’re serious about getting the exact janitorial services you’ve requested.

You commercial cleaning company should provide you with a written invoice for services rendered. This invoice should include the following items:

  • The janitorial service’s name, physical office address and license number.
  • An itemized list of all commercial cleaning services performed.
  • A complete list of all cleaning supplies used (if you are expected to pay for cleaning supplies. This isn’t necessary if cleaning supplies are included in your contract rates.)
  • The total cost of the job, broken down into amounts due for cleaning services, extra services requested, labor and supplies.
  • Any applicable guarantees or warrantees provided by the janitorial cleaning crews.

Use the information on the invoice to compare against the work that was actually completed. If items don’t match up or you have questions about what was done, ask your commercial cleaning service representative about the discrepancy.
You may also want to ask the lead janitor to walk through the building with you after the first commercial cleaning service visit so that they can show you what was done and answer any questions you may have.

After they have proven their ability to clean to your standards, you may only need to check the cleaning services on a random basis to ensure quality control.

Written Warranties
If Your Janitorial Cleaning Company Guarantees Their Services

Most good janitorial companies in Santa Clara County guarantees their office cleaning services. If the commercial cleaning company you’ve hired does warranty their custodial services, ask for written proof of the guarantee and what it covers.

A good written guarantee on janitorial cleaning services will include:

  • The janitorial service’s name, physical address and contact information.
  • Specific details including what janitorial services and products are guaranteed and how the janitorial contractor will deal with warranty claims (refunds, complimentary office cleaning, immediate replacement services, replacement of janitors/custodial staff on your job, termination of the janitorial contract at your request, etc.).
  • Your responsibility when filing a complaint and how you should report problems with the commercial cleaning services.
  • The exact terms and limitations of the guarantee.
  • All exclusions to the cleaning services guarantee must be in writing and presented at the same time as the written warranty.

Frequently Asked Questions
Common Questions for Local Janitorial Cleaning Companies

Q: Why choose Diamond Certified janitorial companies instead of uncertified custodial services?
A: Diamond Certified helps you choose a janitorial service company with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only custodian companies rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified janitor in your area.

Q: Why hire a janitorial service company?
A: Some companies choose to divide cleaning duties among employees or hire in-house janitorial staff. However, this can add a burden to employees who are already busy with other work. This can mean the office cleaning isn’t done correctly or frequently enough, leaving offices dirty and unwelcoming. It can also mean damage to the facilities if the employees don’t have the skill and knowledge to use janitorial supplies correctly.

Many companies choose to hire outside janitorial firms to handle their office cleaning and business janitorial needs. Most janitorial companies provide  flexible schedules and fair fees for the amount and type of janitorial cleaning required.

Q: What types of buildings do janitorial firms clean?
A: Local janitorial firms offer the following custodial services:

  1. Office building cleaning  / professional building cleaning
  2. Banks and financial building cleaning services
  3. Office parks and corporate campuses
  4. Medical offices / medical research buildings / biopharma facility cleaning
  5. Commercial real estate cleaning
  6. Transportation and aviation facility cleaning
  7. Restaurant cleaning
  8. School cleaning / K-12 and higher education janitorial services
  9. Church cleaning services
  10. Factory / industrial facility cleaning
  11. Retail store cleaning / shopping mall janitors
  12. Government building janitorial services
  13. High-tech facility cleaning
  14. Homes/private residences

Q: Is janitorial cleaning different than house cleaning?
A: Yes. While some facets are the same—vacuuming, sweeping, trash removal, bathroom cleaning, dusting and plant watering, for example—most house cleaning companies don’t provide business cleaning and most janitorial companies don’t provide house cleaning. Commercial cleaning services use different janitorial supplies, and often are tasked with cleaning projects that aren’t needed in homes, such as floor stripping and waxing, dayporter services, high-traffic area cleaning and boardroom cleaning.

In addition, much janitorial work is done during the evenings and weekends when businesses are closed to the public. Housekeepers may not be able to provide the type and timing of services required for many professional businesses.

Q: Will I have to sign a long-term contract with the janitorial company I choose?
A: This depends on the commercial cleaning company you choose. Most janitorial companies have some type of contract term, which may be monthly, bi-monthly, quarterly or yearly. Good janitorial companies provide clear contracts that protect your interests and theirs. As with any service company, you should have the option to try out the services before you sign a long-term contract, and there should be specific verbiage in the contract you sign that details how you can get out of the contract without large penalties if there is a problem with the services or the janitorial staff. Never sign a long-term contract with a commercial cleaning company you’re not comfortable with.

Q: How much do janitorial cleaning services cost?
A: The cost of your janitorial cleaning services depends on what commercial cleaning you need and the frequency you require it. Labor is the largest expense in janitorial services, so keep in mind that the cheapest commercial cleaning services may not be the best. That’s because some janitorial services hire unskilled cleaning staff rather than professional custodians. This may mean the work will take longer, be unreliable, or that you may face high turnover rates in cleaning staff or damaged facilities if the staff aren’t knowledgeable about the cleaning products and janitorial equipment they’re using.

The contract you sign with your local janitorial service should clearly outline the cost of the service, including any extra fees for emergency janitorial cleaning or janitorial supplies.

Q: What do I need to supply? 
A: Some janitorial services provide all cleaning supplies, janitorial equipment, soap, trash can liners and paper products. Others ask that you provide some or all of the janitorial supplies needed to clean your facilities. Some will provide certain supplies, but request that you provide certain cleaning solutions or items that you prefer, such as green cleaning solutions or microfiber towels instead of paper towels. So talk with the cleaning services you’re considering and factor the items you need to supply into the cost of their service. You should also ask whether or not you’ll be expected to provide storage space for paper products, cleaning solutions.

Q: What are green janitorial services and why should I consider them?
A: Green janitorial services are those that provide eco-friendly custodial services. This is often accomplished through lower water usage, environmentally friendly cleaning products, recycled paper products, unscented cleansers and non-toxic janitorial supplies. Green janitorial equipment is also an important component of environmentally safe commercial cleaning because tools including HEPA-filters, microfiber cloths and mops, and two-chamber mop buckets are designed to prevent dirt from contaminating surfaces and reduce the amount of chemicals required for cleaning. Green janitorial cleaning companies are often preferred by office personnel who have allergies, asthma, sensitivities to chemicals, or in locations such as daycare centers and schools.

Q: Should I hire a janitorial firm that performs background checks on their employees?
A: This is an important factor for many companies when hiring a good janitorial service, especially in high-tech, medical offices, schools or other buildings where the safety of individuals, property and intellectual property are at stake. Keep in mind that most business owners don’t see the janitorial staff, because most commercial cleaning is done at night or on weekends. So it’s important to hire a trustworthy janitorial service. Many people like the added security that comes with knowing the backgrounds of those providing their commercial cleaning services.

Q: What are day porter services?
A: Day porter services are often provided to shopping malls, apartment complexes, large business parks and other areas that require janitorial cleaning services throughout the business day. Typical day porter services include spill clean-up, sweeping, light vacuuming, window washing, fingerprint removal, mopping, bathroom cleaning, paper product replacement, soap refilling, trash removal, high-traffic area monitoring, lobby maintenance, kitchen and cafeteria cleaning and exterior building maintenance.

Q: Can janitorial companies clean areas with lead paint?
A: This depends on the janitorial company and the area in question. If the lead paint is flaking, chipping or is otherwise coming free from the surface, you should have a certified lead paint removal specialist in your area remove the paint and clean the area to reduce the risk to you and others. Lead paint is known to cause cancer, and by law, lead paint removal must be done by a certified professional. If the areas you need to have cleaned are known to contain lead paint but the paint is not chipping or disturbed, talk honestly with your commercial cleaning company owner. He or she may not want to clean the area, or may be very comfortable providing janitorial services. In either case, caution must be taken not to crack, chip or damage the paint to avoid exposure to potentially hazardous material.

Q: How should janitorial companies deal with asbestos?
A: Some janitorial companies will not deal with asbestos and will refer you to an asbestos contractor. Others will clean those areas. However, asbestos is known to cause cancer and other illness, so you must legally disclose the presence of asbestos to all individuals working in an area where they may be exposed. Janitorial companies who are licensed to clean up hazardous materials and others who work in potentially hazardous areas should have the proper equipment to prevent the spread of asbestos fibers.
