About A1 Quality Construction

A1 Quality Construction has traded since 1987 and describes "nearly 40 years of hands-on experience".

Its California contractor licence number is 639924.

On who does the work, the site says "our owners and expert installers bring craftsmanship, precision, and pride to every project" - so the owners are involved in the work rather than only in sales.

On its approach: "Our clients appreciate that we treat every home as if it were our own, combining modern installation techniques with time-tested construction expertise to achieve lasting results." The site explains the company name as reflecting its standard - "attention to detail that reflects our name - Quality."

The site has a Client Testimonials page, window and door image galleries showing completed work, and a blog.

The site does not publish the owners' names, the number of installers, whether installers are employees or subcontractors, insurance or bonding details, manufacturer certifications or dealer status for the brands it carries, trade association memberships, review scores, or the number of projects completed.

On its focus: "we specialize in window and door replacement services designed to enhance your home's comfort, beauty, and energy efficiency. With nearly 40 years of hands-on experience, our owners and expert installers bring craftsmanship, precision, and pride to every project."

On project size: "Whether it's a single window replacement or a full exterior renovation, our team ensures the work is completed with care and attention to detail." So the company takes single-window jobs as well as whole-house work.

Where A1 Quality Construction works

A1 Quality Construction is based at 535 Salmar Avenue Ste C, Campbell, CA 95008-1430, in the South Bay near San Jose.

On the area served, the site states: "We've proudly served homeowners throughout the San Francisco Bay Area, earning a reputation for exceptional workmanship and reliable service."

So the published service area is the San Francisco Bay Area, worked from the Campbell base.

The site has a Service Area page, but that page carries no city or county list - it shows only the company's contact details, so no specific towns or counties are published anywhere on the site.

Contact details are phone (408) 836-6866 and email fp.a1quality@gmail.com. The California contractor licence number is 639924, which allows a homeowner to check the company with the Contractors State License Board.

The site does not publish opening hours or opening times, a list of cities or counties covered, how far it travels, travel charges, or whether it works outside the Bay Area. Those are answered by calling (408) 836-6866.

Lists South Boston, Bay Village, Campbell, San Francisco, and San Jose as a location. Names California, Campbell, and San Francisco as a service area. Areas beyond these are not published.
