ADVANCED WINDOW SYSTEMS has been installing windows and Patio Doors for over 30 years in San Mateo County. We are a small window and patio door installation company serving San Mateo County. We specialize in window and patio door installations using Andersen and Milgard exclusively. These two companies are each over 50 years old and offer parts for older windows and doors that the have manufactured.
They also have a diverse line of products including Vinyl, Wood, Fibrex, Fiberglass and Aluminum. I have been working with both companies for over 30 years. Low-emissivity (Low-E) glass is window glass that has been treated with an invisible silver oxide metallic coating that creates a surface that reflects heat back to its source.

I am a long time customer. In 1991 Advanced Window Systems installed a bay window in a dark bedroom for me that completely transformed the room. In 2003 they installed a lovely wood framed sliding glass patio door. I have just replaced all the remaining single pane windows in my house. They are lovely and I couldn't be happier. The installation went smoothly and was exactly on the schedule and budget predicted.

I would give them 10 stars if ur was an option. These guys are the best! Super professional and decades of expertise. They offered lots of support and help making window selections. They are conscientious about cost offer practical solutions and stand behind their work and products they use. We had an issue with the lock on our Anderson French door 3 years after they installed it and they responded immediately, made the repair and with no charge. Amazing. Unheard of in the industry. I've recommended them to everyone!!

After posting my review, I have been contacted by the owner Don (on the original email thread that I started with him about 6 weeks ago). I appreciate that AWS is a small business but frankly after receiving his typo/spelling mistake/grammatically incorrect filled email, it does not leave me with any better feelings about his business. He indicated that he asked for my address to determine what kind of home I have as his business can't service certain types of residences (like townhomes, condos) and if at the get-go he had said that instead of just asking for my address with no explanation

After contacting 4 different companies and reading Yelp reviews, we were pretty sure we'd use Advanced Window Systems. First, Julie was meticulous when measuring and assessing for our estimate which was very reasonable. Since we were replacing 35 windows, we wanted to be sure. It turns out Don and Julie have a personal passion for doing excellent work!!! They definitely deserve 5 stars!!!!!

If you want to support a local business for your windows, I recommend Don and Julie. Their work is professional and they're efficient. Not to mention how nicely they clean up after the installation is complete - I've worked with lots of contractors who leave a mess. I checked their references and looked at other work they completed - everything checked out. I'm pleased with my installation and would use them again.

I can't say how happy I am with my new windows and the prompt customer service and responses I received from Julie when shopping around to have 2 single-hung Milgard windows replaced with 2 double-hung windows (long story, which I'll spare you for another time). For any of you who have shopped around for a window company, you know that most places want a large job (consisting of having 5 or more windows replaced), and I was turned away by several because of my need for just 2 replacement windows. I also chose not to go with the companies I previously used due to the difficult, and almost

I stopped by Advanced Windows when I was trying to get quotes for putting in 4 new windows at my home. I didn't exactly know what I wanted then, but Don was extremely patient in explaining what's involved in installing some of the more complicated windows (such as round ones). In the end, I chose another company for a lower quote but I soon learned to regret the decision, because each and every one of the 4 windows turned out irregular -- noticeable by eye alone.
I called Don for help, and he offered free advices on some photos I sent him. I learned a lot from this process, and would

I had 4 contractors come out to estimate for a few windows in the house. Don and Julie are a family owned business and I found them to be honest/straightforward with their pricing, pleasant to work with, and extremely knowledgeable about window installation which comes with 20+ years of experience. In fact, they had installed some other windows in our house 20 years ago (for a previous owner) and Don still recognized his work since it was a complicated installation!
In comparison, the other "big" vendors had salesmen who tried to do the hard sell (if you commit now we'll give

After working with numerous contractors trying to get our first home ready to move into, Advanced Window Systems was seriously a breath of fresh air. They came on time for the initial bid, emailed us the estimate after taking a few days to crunch the numbers, and came back with a great price on quality Milgard Tuscany windows (lower than 3 other bids for the same exact windows). We waited about a month to actually order the windows because we had a headache of an Escrow period, but when we finally were ready to order, Julie went over all the details to make sure we had the grid designs, etc that

We had Don and Julie install four windows and a sliding patio door to replace the old, lead-painted decaying ones on the back of our house. This husband-and-wife team are courteous and prompt and the windows, which were prefinished inside and out, looked great as soon as installation was over. They trimmed out the interiors beautifully and caulked with color-matched caulk inside and out. (All that is left to do is paint touch-up on the exterior.) They masked off the work area and when they were done I swear it was cleaner than when they started (their grown kids came to help with cleanup!). The

This company is family owned really great people and they are very knowledgeable and informative. They recently began an installation of huge picture windows for a company I work for where the windows had failed and were fogging up between the double glass. The difference already between the windows they changed and the windows that will be changed is HUGE! The glare is significantly reduced the heat as well and the clarity is phenomenal! I would definitely recommend this company to anyone.
