Quality Windows & Doors offers residential installation services.

Quality Windows & Doors, Inc. is a trusted provider of premium window and door solutions for both residential and contractor clients in Alameda and Contra Costa Counties. Specializing in the installation of replacement windows and doors, the company offers a wide variety of styles to suit every need. Its Pleasanton showroom showcases top-tier products from renowned manufacturers such as Andersen, Marvin, Milgard, ProVia and Masonite.

With over 40 years of experience in the window and door replacement industry, President Eric Warm has successfully led several well-established home improvement companies throughout the Bay Area. QWD was established in 1989 and has earned numerous industry certifications, including the prestigious InstallationMasters™ & AAMA accreditation. In 2025, Eric will pass the leadership role to his son, Billy Warm, who currently serves as vice president. Although Eric will step back from daily operations, he will remain actively involved, offering his expertise and overseeing the company's ongoing success.

Quality Windows & Doors, Inc. is committed to providing an exceptional customer experience. The company’s goal is to meet every client’s window and door needs with professionalism and customer satisfaction.

"Our mission is to provide an unparalleled window and door purchasing experience, driven by our extensive product knowledge and unwavering commitment to excellence. Our skilled installers complete each project efficiently and to the highest standard in the industry. Our dedicated sales and office staff offers seamless support throughout the entire process."

Pre-screen aggressively by telephone.
You’ll want to "pre-screen" window contractors by phone before you hire them. Though they’ll be asking you questions about your project—location, number and type of windows, timeline—think of this phone call as your fact-finding mission. You want to eliminate candidates who don’t meet your expectations. So answer their questions, but make sure they answer yours as well.

There are many questions you can ask, and many will be dictated by your own specific circumstances. But make sure to ask these five:

• How long have you been in the construction business?
• What is your specific experience with window installations?
• Is there a specific window you use or recommend? Why?
• Do you have your own installation crew or do you subcontract the work?
• What are your payment terms?
• Are you on site during the installation process?

It’s also a good idea to ask how the company handles problems once the project is complete. They should also be able to provide a list of referrals, preferably in your area. And find out about warranties beyond what the manufacturer offers.

If possible, work with installers who have exclusive relationships with established, name-brand window manufacturers. You won’t want to work with a company that buys from second-hand shops or, even worse, out of someone's trunk. You can save money with cut-rate products, but only in the short run. When they break down, you'll be left with more cost and inconvenience. Suppliers should be reputable and have a fixed address.

For Quality Windows & Doors, the company slogan, "A Window Company You Can Trust" is more than just a slogan. It is a way of doing business each and every day. Company president Eric Warm adds, "And we will always keeps your property clean."

Those, say Warm, are his company's guiding principles: Trustworthiness and cleanliness. If necessary, you can leave a Quality workers alone in your house without worry. Not only will they perform the work to your complete satisfaction, they will also take extraordinary care to protect your floors, carpet, driveway, and flower beds. You'll find your home –your "domain," as Warm calls it– in exactly the condition you left it. And there is never any smoking anywhere. Not in your home, not on your property, not in the street.

Quality Windows & Doors performs all jobs with utmost attention to detail, even so-called fast replacements: putting new windows and doors over old frames. Though these retrofits are theoretically less difficult, Quality installers perform them as meticulously as higher-end jobs.

It's on those larger projects, however, where Quality Windows & Doors' superior workmanship is most on display. Some jobs are inordinately complex, requiring stucco work, trim removal, wall cut-downs or moving of electrical wiring. With its large crew of highly skilled installers, Quality Windows & Doors has the experience and flexibility to undertake these complex projects. It has received an "Outstanding Customer Service Achievement" award from Andersen Windows and "Best of the Valley" by the Alameda Newspaper Group. It is also a Better Business Bureau Accredited Business.

I would tell them that they are very responsive to your needs. We had one issue with a screen not being wide enough. They came out the next morning, measured, and it's coming tomorrow. I have already referred two people to them who used them, and they were blown away.

The whole thing, we went to the store, picked out the windows, made an appointment, and every appointment they were on time. It took two days to install. They were on time and didn't leave a mess or anything, so you couldn't even tell they were here.
