In 1990, I was just out of high school and working for a glass company in Malibu, California. I had an opportunity to move to San Diego and partner with another North County San Diego glass company. I went to contractor's school to learn the legal aspects of the glazing industry, as I had already learned the trade, and received my Glazing Contractors License in 1993.

Advanced Windows installed 11 vinyl windows and 3 sliding doors to our property. They did an excellent job. They showed up when they said they would. They finished the job on time. We would recommend Advanced Window to any one that needs windows or sliding doors. Wally Garcia Contractor

Don't bother making a appointment for a quote. They will make an appointment and leave you waiting. Try someone else.

We immediately told this company leave our property after hearing the unmasked owners say they were never getting the covid vaccine. We have a chemo patient in the house and are now terrified that these unvaccinated and unmasked ppl brought covid into our home and we are going to get a covid rapid test as soon as possible. Don't make the same mistake we did and make sure you confirm the vaccination status of any/all workers at this company coming into your house.

The disgruntled employee did not walk off the job. He was forced to quit after his boss texted his brother saying "if you don't go caulk these windows you are quitting". Then continued to claim "you are not a doctor you won't make more money" "glaziers cap at $20" "I know you don't understand what a bonus is". All of this, and more, was said after a response saying we do not feel comfortable doing this job without my injured dad who has worked there for over 20 years (with no benefits, steady wage, retirement) could not go with us.

We weren't given any chances for the 2 years I was there or the 6 years my brother was there. It's honestly unbelievable how you can say I don't know how to run a business when you don't even know how to treat your employees. The way you and your husband responded to a 19 and 23 year old was truly disgusting and childish. We NEVER asked for money not even when I was getting payed $10 an hour doing extremely dangerous stuff.

We never asked for anything or gave any problems and out of those 1000's of happy clients how many where happy because of us? I know the true prices of glass and windows and everything you do so how can you tell me you are not taking advantage any time you can, and for your own benefit because your employees can't live a livable wage. Also the employee NEVER walked off a job and got a second chance and didn't take it. Please do not lie.

Honestly over priced. As a glazier I KNOW and have SEEN them they take advantage any opportunity they get! They WILL overcharge you and for their own personal gain because they can NOT give there employees a livable wage. Don't fall for the lies they WILL tell you. Just keep on looking.

We love Advanced Windows and will continue to give them out business for the remaining windows we have on our home. Carl and Holly always do their best to make sure we are happy with the end product. The installations by Vincent and RJ was wonderful. They were polite, respectful and did a great job with the installation. They took their time to walk through the end product and demonstrated how to clean and maintain the windows. Very happy to give our business to Advanced Windows!

Vince and RJ did an amazing job only window project. Awesome, friendly and pros. Impressed with how they took the time to clean every detail. They were informative answered questions even did a walk through and window demonstrations. Would of never knew I had a secondary lock and a breeze lock if they didn't take the time to show me! Thanks

We purchased a home in Valley Center a few years back with Milgard windows. They are only 1-15 years old, but are very hard to open and one of the brackets broke completely. Milgard referred us to Advanced Window. They were very friendly, walked me through the process so I could buy the parts and fix it myself. Also, gave me a quote if I would rather have them come out and do it.

We have fixed our window and couldn't be happier. If we ever need to have them replaced or are in need of more windows, this will be my place. Their quote was very reasonable.

I am so thankful Advanced window came to the rescue for me and my family! They are by far the best window company. Holly and Alicia were so helpful and was able to get the best price for our family with a quality window that has a great warranty. The installers Sergio and Will were great they showed up early and were efficient and made the job seamless! I will be using them in the future and will recommend them to everyone! It is hard to find a great company that is reliable and I am so grateful I found them.

Our 45 year old windows were leaving us hot in the summer and cold in the winter. Karl was very helpful when he was taking measurements, and gave us recommendations. We chose Plygem windows and are happy with how well they look on our old home. Unfortunately Plygem made two of the windows incorrectly, which luckily was spotted by Sergio, our installer, before he took out the old window.

But it did cause the project to drag out another three weeks. I can't say enough nice things about the installers, they went out of their way to make sure everything was spotless and in order before they left. I would totally use them again and recommend them to my friends.

Did a very good job replacing french doors that were leaking water into our house during rain storms. The problem was solved. Excellent customer service.

Good experience. I purchased a glass sliding door with a built in doggy door. Fast installation, good quality workmanship and a reasonable price. We are thrilled with the door and had a great experience with this company!

We had over 52 windows/sliding doors installed over 12 years ago. Some seals failed and Advanced Windows replaced them with only charging for labor and not materials. No charges at all to us for windows covered by the original warranty of 5 years (parts and labor). Work was done in a very professional way by a great team of guys. We decided to have 14 additional new windows installed in our duplex rental property.

Great work and fair price. These new windows now have a lifetime warranty. Our tenants love the look, safety and easy maintenance. It is a great upgrade to our investment property. Thank you Carl and crew. Sharon and Don J.

Their work LOOKS nice but the quality is lacking. I have had my windows and doors since Feb. 2016 and so far all the screen doors have broken. The materials are super cheap. The locks on the windows constantly break which means I can't open or close the windows depending on what position they are in when the window breaks. Do yourself a favor and shop around.

A very nice couple working hard to build a good neighborhood company. Love speaking to them on the phone, good demeanor and always ready to help. They sold and installed double-pane windows and sliders for my entire house. Excellent quality and only had to come once to install everything. Anytime I have a question they are on it immediately.

Our screen door got trashed after someone walked thru it 3 times. (it was funny the 1st time-- the 2nd and 3rd. not so much) Alicia told me she could get me replacement parts if I ever needed her services. She helped me find the "code" number plate located inbetween the glass panels and this gave her the correct measurements of the replacement screen door for a perfect fit. Super quick turn around! Super good people to work with!

I have used Advanced Window several times on homes that I have owned. They have always done a great job at a reasonable cost. I have also recommended them to people I know and have not regretted it.

They did a good job installing the windows and doors but did a number on my blinds. Several slats were broken and had to be replaced (by me). My advice would be to remove window coverings yourself or closely supervise them when they take them down and put them back up. They did return to fix a few glitches: a security door that needed bolting down, a leaky sliding glass door edge that needed re-sealing and a nicked paint spot.

When I first moved in back in 2001 my townhouse was hot and noisy. Living next to a busy street I was woken up by car noise in the morning and my binge movie watching was occasionally interrupted by sirens. When I got home from work I was greeted by an inferno as my glass patio door was west facing. After doing research I decided to replace the crappy single pane glass doors and windows with new energy efficient dual pane low E glass.

I got quotes from a few companies and settled on Advanced Window Contractors as the owner Carl gave me a real good price and he was a nice smart guy I thought I could work with. Carl gave me some options and I settled on getting Milgard doors and windows as there was a lifetime warranty and they had laminated glass that was suppose to reduce noise above what regular dual pane windows would.

The install went well and Carl has taken care of some issues and a replaced a broken glass pane over the years. I have them take care of all my window needs now. Getting a good warranty is important as after 12 years the rollers that glide on the track failed and the patio door wouldn't move easily. Milgard came out and fixed it in less than an hour.

Back to the living room inferno. The low E glass has made it much cooler but it still gets hot. I put up a big patio umbrella to shade the patio door and that made it a bit cooler. Then I put up a 2nd patio umbrella so that 80% of the sun is now blocked. It's not hot now. I notice they have a new improved low E glass formulation called low E3. I'd get that if I moved into a new place with single pane glass.

Nice quality, good price and very nice owners. I've used Advanced Window twice, for two different houses and both jobs turned out great and were priced very reasonably considering all windows were custom sizes. I've noticed a big difference in both comfort and heating bills since getting new windows. No complaints other than the windows took much longer to be delivered than originally estimated, both times. I'd still use them a third time for sure, but would anticipate a longer delivery time than quoted.

1 star for the plygem window product that Advanced Windows carries. Otherwise, I can't say enough to stay away from this devious business. The crew was rude, never once introduced themselves to us, they trekked mud through the house and made no attempt to clean before they left, bunched a rug into a corner because apparently it was in their way, they chipped one of the bathtubs but their team said they didn't so that was that, chipped the dry wall above the window (must have been there too!).

We were having them install two large bedroom windows, 2 small bathroom windows, 1 static entry way window and a sliding door. Quoted us a day of installation took three weeks to complete (on top of the 6 weeks it took to order the windows; quoted 3 weeks!). Windows were put on the first day nicely, no scuff marks or the sealant remanence, but boy oh boy we had issue after issue with the sliding door.

They installed the door wrong, the stucco that they used didn't match the house (despite the numerous conversations and pictures that they requested to match the existing stucco color - their response was that the contract said no paint. Ok, why on earth would I think if you were color matching the stucco that I would then want you to paint it?) and on top of that they kept telling me a base coat and texture was all they were doing and the texture looks great!

After we PAID someone else to paint, it was apparent that the texture was crap. They got stucco all over our brand new pavers, which actually had to be replaced; we tried to pressure wash numerous times but there was tape permanently stuck under the stucco on the pavers so there was no salvaging. After a number of complaints, they attempted to fix some of issues, like installing the door properly. However, towards the end of the three weeks, we felt they were not addressing our concerns and were hiding behind language in the contract that I as a common consumer would not know to question.

My last straw was they sent contractors to trespass on our property without permission. All in all, stay away from this business; they produce low quality work with low quality workers and purposefully provide misinformation.
