I just recommended them to my neighbor. They do great work. They are on time, thorough, and are in and out. We have used the same girls for several months, and they are really sweet girls.

Comparative Summary

Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for house cleaning companies that have earned the prestigious Diamond Certified award. For Optimum Cleaning Services, the key to achieving and maintaining high levels of customer satisfaction is simple: take a comprehensive approach to cleaning that ensures every client’s needs are met. “We don’t view our job as just cleaning,” says co-owner Jim Wu. “We’re very detail-oriented when it comes to our services, we’re flexible with our scheduling and we always back up our work.”

Optimum Cleaning Services has the equipment and training to clean all types of residential and commercial properties throughout Santa Clara County. The company offers its services on a weekly, bi-weekly and monthly basis, and it also performs one-time cleanings for people who are moving in or out of their houses, apartments, or office buildings.

Unlike less experienced house cleaning companies that hire inexperienced workers and provide them with minimal training in an effort to reduce their operating costs, Optimum Cleaning Services carefully chooses its staff members and trains them to emphasize quality in every aspect of their work. “Quality is the most important part of the services we provide, and everyone who works here understands that,” says Mr. Wu. “We communicate with our customers and ask for their feedback, and we perform inspections to ensure all work is completed to our high standards.”

Optimum Cleaning Services further differentiates itself from its competition by not requiring its clients to sign lengthy agreements or contracts. “Our customers can set up a cleaning schedule at their convenience or just call when they need us,” says Mr. Wu. “Rather than being locked into a contract that specifies how often we come to clean, they can book on an ‘as needed’ basis, which they really appreciate.”

Industry Info

To get the most out of a house cleaning service, it’s important to plan ahead. Hiring a professional house cleaning company can save you time and stress, and even though you don’t have to do much more than schedule the services, there are a few simple steps you can take to get the most value for your money.

Jim Wu, co-owner of Optimum Cleaning Services in Mountain View, says you can get a better cleaning job by starting with a cleaner home. “The more you de-clutter your house, the more you’ll get your money’s worth. With a less cluttered home, cleaners can get more access to the surfaces they need to clean.” Keeping clutter to a minimum can also help prevent confusion and misplaced items. “If you have a lot of clutter, it can be hard for the cleaners to know where to put things. This can cause problems if they put items in places you don’t expect.”

Before the first cleaning appointment, talk to your house cleaning company so you can make sure you get the services you want, pass along any special requests, and learn what the cleaners will and won’t do. For example, many cleaning companies won’t operate dishwashers and washing machines in their clients’ homes, and some even have special requests for how to access the home and what to do with pets.

Let your house cleaning company know if you or your family members have allergies or sensitivities to certain products or scents. If you want the company to use certain cleaning products, find out if that’s something they’re willing to do or if they have their own product preferences. You should also find out if the company expects to use your cleaning materials (vacuums, brooms, dust cloths, cleaning solutions) or if they bring their own.

Frequently Asked Questions

Q: How often will you clean my house?

A: It depends on several factors, including how many people live in your house, how many pets you have, how much usage your home gets and so forth. Once we determine your specific needs, we can set up a schedule that works for you.

Q: How many people will be cleaning my home?

A: In almost every case, we’ll send a team of two people to clean your home. If it’s a bigger job, we may send more people because it can take longer.

Q: Will the same team clean my home every time?

A: We try to have the same team clean your home every time. We can’t guarantee it, but we do our best.

Q: Do I need to be home when you come to clean?

A: No. The majority of our customers aren’t home when we come to clean—they give us a key so we can get in and out on our own.

Q: Do I have to sign a contract?

A: No, you can call when you need us or set up a schedule at your convenience.

Q: What should I do with my pets while you’re cleaning my home?

A: We cover that during our interview process. We’ll work with you to deal with your pets in a way that makes everyone comfortable.

Q: Is it proper to tip the cleaning staff?

A: That’s completely up to you. Some of our clients tip their cleaners every time, and some only give tips during the holiday season. Since many of our customers request the same cleaners for each visit, they get to know and trust those cleaners and want to tip them.

Q: Can you do my laundry?

A: We can change your sheets, but we generally don’t operate any machines in the homes we clean.

DIAMOND CERTIFIED EXPERT CONTRIBUTOR ADVICE & TIPS FROM Jim Wu

Expert CONTRIBUTOR PROFILE

Jim Wu: A Clean Break

By James Florence, Diamond Certified Program Reporter

SUNNYVALE — Soon after moving to the United States from China at the height of the tech boom, Jim Wu secured a steady career as a software engineer. However, as more and more corporations started moving their operations offshore, he began looking for an opportunity that would offer better job security. The next thing he knew, he was running a house cleaning business. “When my wife, Becky, and I started looking for a business to purchase, we wanted to find a service company, mainly because they generally have lower inventories,” he explains. “It just so happened that one of our friends was selling her cleaning business, and it ended up being a perfect fit.”

Today, as owner of Optimum Cleaning Services, Jim says he enjoys the social interaction his second career entails. “It was a big shift to go from almost no customer interaction to dealing with people every day, but I really like talking to our customers, especially when I can offer help. One customer even sent us a thank-you note that said our service saved her marriage!”

A resident of Saratoga (where he lives with Becky and their children, Justin, Erin, and Victor), Jim expresses his appreciation for the temperate Bay Area climate. “You can’t get weather this nice anywhere else,” he says. “When I first came to the U.S., I worked for a consulting company based on the East Coast and went to their headquarters for two weeks of training in December. It was so cold, and when I returned to California, I was glad to be back.”

Outside of work, Jim spends the bulk of his time with his family. “I like the fact that I have control of my schedule because it enables me to devote enough time to be with my kids,” he affirms. “We like swimming, hiking and taking occasional camping trips to Yosemite.”

In regard to his professional career, Jim says it’s important to find a balance between operational efficiency and customer service. “As a business owner, I want to see things running efficiently, but at the same time, we’re in a service industry, so I understand that the customers’ needs are the number one priority. I think it’s easy for a company to go to either extreme, so I always want to strike that balance between keeping our business profitable and our customers happy.”

When asked the first thing he’d do if he were to retire tomorrow, Jim says he’d do some extensive traveling. “I would probably plan a tour of Europe or something. Right now, with the kids and the business, we’re somewhat limited in how far away we can travel, so it would be neat to have the freedom to see more of the world.”

Ask Me Anything!

Q: What are your favorite sports teams?
A: The Golden State Warriors and the San Francisco 49ers.

Q: Coffee or tea?
A: Coffee for on-the-go, tea for leisure time.

Q: What’s one website you visit on a daily basis?
A: Yahoo.com for news, stock market updates and email.

Q: What’s your favorite dessert?
A: Cheesecake.

Q: What’s your favorite holiday?
A: Christmas—the family is together and everyone is happy.

  • How to Prevent Water Spots on Glass

    SUNNYVALE — A common problem with glass shower doors is the formation of water spots. Not only do these spots obscure the clarity of glass, they can also become permanently etched into it over time. The good news is, if your shower door is less than two years old, it’s unlikely that your water spots are permanent, so there’s still time to take proactive measures.

    Preventing permanent water spots entails just one simple step: applying Rain-X to your shower doors. Typically used on car windshields during the rainy season, Rain-X is a water repellent, which means it causes water to run off glass surfaces rather than stick to them. With the regular application of Rain-X to your shower doors, you can stop water spots before they start.

    You can find Rain-X at any auto supply store. Keep in mind that after cleaning your shower doors with a glass cleaning product like Windex, you’ll need to reapply the Rain-X coating.

  • Video: Preventing Water Spots on Glass

    Complete Video Transcription:

    SUNNYVALE — Host, Sarah Rutan: If your glass shower door is less than two years old, it’s not too late to get proactive about preventing water spots. Today we’re in Sunnyvale with Diamond Certified Expert Contributor Jim Wu of Optimum Cleaning Services to learn more.

    Diamond Certified Expert Contributor, Jim Wu: For someone who has problem with water spot on their shower glass door, here’s a tip. If your shower glass door is less than two years old, what you can do is you can apply Rain-X on the glass.

    Rain-X is a water repel agent. What it does is it will stop the water stain on the glasses. Therefore, you’re not going to have water spots to start with. If you use Windex to clean the glass after that, you’re going to break the coating, but you can apply the coating afterwards. You can find the Rain-X in any of the auto shops like Pep Boys and any other stores like that.
