Diamond Certified Researched Articles on Optimum Cleaning Services

researched article

Owner Jim Wu talks to a customer on the phone.

Optimum Cleaning Services has been providing premium cleaning services for customers throughout Santa Clara County for 21 years. The company uses environmentally-friendly cleaning products and offers services on a weekly, biweekly, monthly, and one-time (for special occasions) basis. It also does move-in and move-out cleanings for real estate agents and rental property owners.

Owner Jim Wu says Optimum Cleaning Services’ reliability is one of its most important attributes. “We always try our best to be available based on our customers’ needs. We want them to enjoy their lives and not worry about cleaning their houses. They know we’re just a phone call away and they’ll be taken care of.”

Optimum Cleaning Services’ staff is comprised of highly experienced cleaning professionals who are trained to adhere to the highest industry standards. They understand the importance of customer satisfaction and work hard to achieve that on every job. “Our cleaners are definitely our biggest assets,” affirms Mr. Wu. “We’re confident sending them to our customers every morning because we know they’re going to do whatever it takes to make sure the customers are satisfied.”

“Our goal is simple: provide reliable, detail-oriented services and make sure our work is the best it can be. We appreciate our customers and want them to depend on us for all their cleaning needs. If they ever have any issues or concerns, they know we’ll be there to help them.”

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.

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."

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.

They do a good job generally, but there are some internal changes going on. We just found out our cleaning team isn't coming back, so we're disappointed about that.
