What People Are Saying

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?

Charles Window & Door is the best in the business, with service, quality of materials, workmanship, and the people who know how to do it right.

– Michael in Sonoma

They provided high quality from the very beginning. I’ve been in the construction business for 40 years, and I appreciated their ability to perform in a very professional manner.

– Ed + Linda in San Anselmo

I suggest Charles Windows and Doors. They advised me on a big job of replacing windows, ordered the batch of them in the fall of 2021 and installed them in May of 2022. Did a great job on every detail from start to finish.

– Laurie G

Charles Doors just replaced three sliding glass doors and two windows in my house and their installation quality is unparalleled. You can get windows/doors anywhere but it’s the installation that’s the most important part of it. They are expensive but I have to say I think they are the best and if you’re going to stay in your house for a long time you want a good warranty on the work.

– Lee B

CHARLES Window & Door Co. In June of 2021 we had 3 sliding glass doors replaced along with multiple single pane windows in our Eicher home. We are VERY satisfied with our new double pane windows and doors. The service we received from Charles Windows was top notch. We interacted with many people from the company and every single person was service oriented and very helpful. A project of this size is never without glitches but with patience and good communication we were able to satisfactorily work every situation through to a good completion. We highly recommend Charles Windows.
