Rated 5 out of 5 by from Loyal customer I have personally used this company six times, they have basically replaced every single window and sliding glass door in my house as I needed to upgrade for energy savings. Everything that they install has worked perfectly have not had issues, the one time that they had to come back and fix something was because they didn’t bring enough spare parts but I had no problem with it he was back within the time period specified and he did the work. Beyond that all of their staff are friendly helpful and encouraging and for that reason we will not use anybody else

Love my windows, loved the price, loved the quick response and now with a minor repair I love the timeliness Milguard responded to correct.

Rated 5 out of 5 by from I had an excellent installation of 8 windows with a great crew. I had the best price, installation, and customer service. I could not be happier with the installation expertise and the personal service of the crew in my home. They were very respectful and knew what to do regarding taking out my old wooden windows and installing the new Milgard windows. I highly recommend this company.

Rated 5 out of 5 by from Best company for Milgard windows I have done multiple properties window projects with the Window Guys installing Milgard's window and sliding doors and I have every single time been so thrilled with my decision I highly recommend them, I have given them numerous referral because I think they do an outstanding job. Milgards commitment to customer service is unmatched, my first Milgard installation was in my Diamond Bar House 15 years ago and when I had an issue after 10 years with one of the windows they came out and took care of it at no cost to me. I would never do any other brand, Milgard is the Best because they back up their product!

Rated 5 out of 5 by from Quick to get quote, order came in early and quick installation Quick to get quote needed, great pricing when compared to other companies, time availability beats others which is why I chose The Window Guys. Windows came in earlier than expected, and installation was fast, completed within one day. However, after installation, they told us one of the screen was not wrapped properly. It took a total of 1 month to get replacement due to several excuses. They also charged us more on our cc since they did not notice the $1k deposit. Just a few missed disconnect but overall a really good experience and would still highly recommend or use them again.

Rated 5 out of 5 by from Separated from Crowded Field I had five very highly recommended companies quote our 26 window replacement project. There were nuances and challenges. We needed opinions, and recommendations. That included fit issues and "new construction " or nail ons versus retros. The Window Guys, and Bill Iverson in particular, stood out. He had answers that others did not. And ideas. And the execution (installation) was probably as good as it gets. These Window Guys are Really Good Guys.

Rated 5 out of 5 by from Great experience! We had a window in a shower of a recently purchased home that needed to be replaced. Called several places for estimates The Window Guys were right in the middle price wise. But the gut feeling I had after the estimate made me go with them. Great guys, professional, on time, cleaned up after themselves, and left me with a beautifully installed window. I would recommend them for any window needs!

Rated 5 out of 5 by from These Guys Get The Job Done! I had 8 retrofit windows, 3 Sliding glass doors and 1 exterior door installed. About 6-7 guys showed up and 6 hours later all work was completed! I was very impressed. Every one got down to business right away. The installers were helpful and professional. I would highly recommend this company for your windows and doors project!

Rated 4 out of 5 by from Sales Team & Intallers were awesome. Office staff is lacking. Bill who provided the consultation and quote was excellent. Installers did an awesome job. I really appreciate them taking extra time to hang my blinds after installation. I love my Milgard windows and will be contacting The Window Guys to do the other half of my home in the near future. The only area where they could use improvement is the office staff. The girl who scheduled the appointment and answered the phone when I called to make my down payment was rude and didn't seem well trained. When I called she couldn't even find my quote and by the time she emailed me the info to pay it was several days later and I had already gone in personally to give my deposit. Customer service & polite front office staff goes a long way so if The Window Guys improves in this area I would give 5 stars.

Rated 5 out of 5 by from Great People if you are thinking about buying from Home Depot don't even though the window prices are slightly higher and better quality they are pro's and have better labor rates overall its so much easier 1 stop shop I have had 3 doors and 8 windows done now more to follow

Rated 5 out of 5 by from Very Satisfied I requested several quotes from other dealers and contractors. I went to Anderson, and American Vision and their customer service wasn't as good as The Window Guys. Home Depot was very expensive and actually gave the most pressure on the presentation. The Window Guys let their price, service and professionalism do the talking and I decided on going with them. I was very glad I did. I have installed different windows before: Anderson, Pella and Milguard. I have always been very satisfied with all 3 and was glad that this company offered a window with known quality. I will go to The Window Guys again when I replace my doors and additional windows on my house.

Rated 5 out of 5 by from Outstanding Company and Quality Installation!! We just had 12 Milgard Tuscany Windows and a Milgard Tuscany Sliding Door installed by "The Window Guys" on July 25, 2016. Wow, are we ever are glad we used this company. The salesman who quoted us named Bill was very knowledgeable about quality Milgard products and about his company qualifications. He was not pushy either. Their prices are great and $75 installation per window is really unbelievable. We used the Hero Program and we are so pleased with our awesome new windows and patio sliding door. The three installers, Aurelio, Sergio and Chava, were the best team of installers we have ever had do work for us. My wife and I are in our 60's so we have had work done at our home many times. These three guys were so professional and skilled in what they did it was amazing to watch them. Top of the line for sure. I highly recommend this company and of course the quality and wonderful Milgard Tuscany product line! A Very Satisfied Customer!! Steve from Moreno Valley.

Rated 5 out of 5 by from very professional, very efficient I had all of my windows and sliding glass doors replaced. They showed up on time and got right to work. It was impressive to see how efficient and fast they were. They did a beautiful job installing everything. They left the house as clean as it was when they came. Watching them work I realized how important it is to hire a company that knows what they are doing. They did not need to hesitate to figure out what to do. It looked like it was second nature for them.

Rated 5 out of 5 by from Excellent work ethic, on time and very efficient The crew that was sent out was enough people to do the job in the time they said it would take. They just did not send out a couple of people and say this is what we have to work with.
