You shouldn’t need to check that the janitorial cleaning service has fulfilled the terms of the contract every time they clean your office space, but you may want to check the company’s work the first time they come to clean your office building.

This will give you a chance to ask questions about, make changes to or provide feedback on the services you’ve received. You may also want to do random checks to ensure the level of service stays consistent.

After the custodial work is completed, the commercial cleaning company you’ve hired should provide you with a written invoice for services rendered.

This invoice should include the following items:

• The San Francisco janitorial service’s name, physical office address and license number.
• An itemized list of all 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 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 controls.

Most good janitorial companies in San Francisco provide guarantees on 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:

1. The janitorial service’s name, physical address and contact information.
   
2. 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.).
3. Your responsibility when filing a complaint and how you should report problems with the commercial cleaning services.
4. The exact terms and limitations of the guarantee.
5. All exclusions to the cleaning services guarantee must be in writing and presented at the same time as the written warranty.

This is usually done before the floor polish is applied because floor sealer fills in cracks, gaps and pits in the flooring to create a flat surface which can be waxed and polished.

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.
