How We Work Installation Products Lifetime Warranty Affordability & Return Ratings & Reviews

Q – Do you have independent reviews of your work?

Yes. We are proud of our exceptionally positive results (highest rankings and 100% satisfaction scores) with Guild Quality, as well as Diamond Certified and Angie’s List. These groups conduct fair third-party surveys (sometimes customers are more direct with third-parties!). Our national award for Excellence in Installation also speaks highly.

Q – What do customers say?

Recently, readers of the Marin Independent Journal chose us as the Best Window Company.  See what some of our customers say:

The Charles Window & Door staff was professional, thorough, and accommodating. They not only did high-quality work, but it was obvious they cared about the customer experience. They even offered to come back and fix some areas of trim and siding after I get my garage doors and decks installed, because I didn’t realize that not having those things completed would affect the siding job. I was very impressed with the company, quality of work, and customer service.

– Arian in Petaluma

Beginning with the sales person, who had all the right answers and ideas, it was a very positive experience. Due to the location of the house, the installation was a very challenging one. The installers, led by a real craftsman, came up with a very impressive installation. None of the problems usually associated with remodeling contractors had to be endured. Even the paperwork and other administrative contacts were very positive. A very recommendable company indeed.

– Hans + Eleonore in Mill Valley

Charles Windows & Door made installation of our windows a very welcoming experience, from meeting with the estimator to the installation of the windows. We would highly recommend this company for your home projects—they are the best.

– Linda in Pinole

I have used this company several times over the years for windows and siding. They have always given me a competitive price and delivered expert craftsmanship and quality. I would recommend Charles Windows without hesitation to anyone seeking a good quality window job.

– Kevin H., San Rafael

I wanted someone who could do the whole thing and provide service. I expect people to be timely and mean what they say. I went with Charles because I wanted the look, and I got what I expected.

– Betsy in Petaluma

I was initially told that Charles Window & Door was the best but was going to be way out of my price range. Turns out they were very competitive, and with the double lifetime warranty and excellent communication, we went with them. Expectations were set and exceeded. I have since purchased again, as has a neighbor.

– Rob + Cassie in San Rafael

Not the cheapest, just the best. They say what they are going to do, and they do what they say. Job done, site cleaned up. Looks great. What more could I ask?

– Jon in San Rafael

Charles Window & Door is a wonderful company and we have been very pleased with them. They have a wonderful staff and wonderful installers.

– Donna in San Rafael

We were extremely pleased with the work done by Charles Window & Door. They installed a new front door in a tricky location, which works perfectly and looks terrific. We would definitely use them again.

They are my first choice, always
