Frequently Asked Questions

Welcome, and thank you for the opportunity to answer your questions. We believe knowledge is power and that it’s important for us to take time to fully answer the myriad of questions involved in completing great home projects. Don’t worry, we’ll make the project simple. We guarantee it.

What can I expect during installation?

We make the installation process as painless as possible to your daily life. We do daily cleanup to spotless (no mess left behind). We will work with you to create a project timeline that will work for your schedule.

Do you offer repair services?

We do! Our Service Department is staffed by factory-trained technicians with years of experience servicing the brands we carry. Our service department can assist you in evaluating or repairing any malfunctioning doors and windows as a billable service. Please visit our Service and Repair page for more information.

How long does it take for windows & doors or to be installed?

Depends on the type of project, it can vary form retrofit, to new windows.

Do my windows and doors come with warranty?

Yes, they all vary slightly from manufacture to manufacture some are 10 -20 years transferable and some are lifetime of original purchaser of the windows. Charles Window & Door will give you written copies of all applicable warranties.

What do I need to do to prepare for installation?

Please make sure there is room for us to work in front of each window—normally four to six feet of workspace is more than adequate. If you are worried about fragile items that are close to the work area, please take them down. We are very careful but preventative measures go a long way.

Do I need to be home during the installation?

No, not at all. We understand the challenges of having work done on your home. If you prefer, we will make arrangements with you to get a key ahead of time, or we will meet you the day of the installation to make arrangements to lock up.

Do I need an appointment to visit the showroom?

We encourage appointments to ensure our team members are available at your preferred time. Feel free to call us at 415-886-1791 or click here to make an appointment now.

Do you have your own crew or do you sub-contract out the work?

All of our crew are employees of Charles and many have been with us for 20+ years. They are all fully licensed, bonded and insured.

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.

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?
