Rated 5 out of 5 by from Very pleased What a wonderful crew- because our house is block and the old windows had steel frames it took them 12 hours but they still cleaned up beautifully and were respectful of our space . I loved walking around and easily opening our new windows because our old crank windows were ......cranky!

Rated 5 out of 5 by from Had to get more windows!! I was only replacing the windows that needed to be replaced. After the transformation I order the rest of the windows for my house. I have a custom Log home in Big Bear Lake. All the log trim is hand carved around the windows and doors. I was very worried about the installation, but David came to my rescue!!! David installed my windows like a millwright pro!! Amazing workmanship!! It went so great I felt it time to do all the windows and David is our installer or no deal! Thank you Design Windows !! We love our New Millard windows!!

Rated 5 out of 5 by from Beginning with Mike and ending with Pete and Sean the installers my experience with Design Windows and Doors was great! I can't say enough about the professional quality of this company. Everyone I dealt with with was knowledgeable, willing to listen to my concerns and answer all my questions. The timeline described to me was followed and the installation went quicker than I expected. I tend to worry about the small things, but Pete and Sean put my mind at ease and did a great job installing my beautiful windows. Can't wait for the next phase!

Rated 4 out of 5 by from Great job! I love my new windows! The process was smooth and easy from the day I sat down with the sales representative to the day of installation. They even called me to follow up and make sure I was pleased with everything even though I initialed all the checklists that the installers provided. This being my first time buying windows I didn't know much at all so I had plenty of questions for the sales rep and he answered them all. I decided to go with the Milgard Tuscany series windows primarily because of the lower price and high end features that it offered. During installation I immediately noticed the difference in sound. I was trying to talk to one of the installer through a closed window he was working on and he couldn't even hear me, whereas before I could have full conversations, hear all the neighborhood noises and wind through my old rattling aluminum frame windows. The installers were cleaner than I had originally anticipated, thought I would have a lot of dirt left around on furniture pieces close to windows afterwards but it wasn't bad at all. They did a really clean finish around the outside of the windows. The windows have really brought the feel of my 1978 home into the 21st century inside and out. I went to sleep with all the windows resting on the vent locks that night which I think have become my favorite feature of the windows because it still allows me to set the alarm! So if your looking to save on your energy bill, reduce noise, and get a great install with excellent customer service without breaking the bank, Milgard is a nice window and Design Windows & Doors installs them very well.

Rated 5 out of 5 by from Best windows ever! You guys were on time and worked very hard to install 3 new windows where there were none before. Professional and courteous all the way through. Your prices were excellent as well. When we decide to install more windows in our home, I'm gonna be calling you guys back.

Rated 4 out of 5 by from Got what I paid for The windows that I purchased were Tuscany Milgard. There were 13 windows. They were purchased for reduction of sound coming from the freeway. The back bedroom windows are heavier and thicker than the rest of the windows. It has cut down the sound from the freeway by 50%. I could have gone higher, but the triple window would looked strange. I am most pleased with the type of windows in style. They open and close much easier than the old windows did, and the security features along with the lack of temperature change from the windows will provide a much more energy efficient home. There are photos of what the home use to look like to what it looks like now. Very impressive! I wish to thank Design Windows and Doors for making this project a success.

Rated 5 out of 5 by from Great company, great insurance policy, great install crew. We love our new windows! And just in time as two days of monsoon rains showed us that there were no leaks. The HERO program works well for us as we need the write off in our retirement. The crew was knowledgeable and able to modify the garden window so that it looks great! We notice that our rooms are cooler as a result of the new windows which replaced our old single pane windows.

Rated 4 out of 5 by from Great Installers I just got 10 Windows and 2 sliding doors installed in my condo. The installers were very nice and they got it all done within 2 days. The Windows look awesome, they appear to be sealed very well. They were good about cleaning up after themselves and communicated very well. I'm happy with everything and would recommend Design Windows.

Rated 5 out of 5 by from The overall experience from the assessment to installation was excellent. My experience with design windows and doors from start to finish was a good one. The initial assessment was thorough and professional, the engineer was courteous and informative, the process wasn't time consuming. The installation crew was 45 minutes early completely skilled and knowledgeable and efficient and the windows are fantastic.
