Design Windows and Doors Inc., Ontario CA

This is the second time using Design Windows Once again, they delivered a spectacular job, going way beyond to ensure a quality install, clean up and even fixing some caulking issues I had on another outside door after they noticed it during the window install. I will use them again when it comes time.

The whole office experience was horrible, they DO NOT COMMUNICATE, they do not like contacting us to let us know what is going on, they say they will call you back and they don't, they are worse then dealing with my baby daddy, the workers were amazing, very professional, but the office staff is HORRIBLE

Working with Design Windows and Doors was such a great experience. The level of professionalism was a welcome change to other experiences we've had with home improvement projects. They are in constant contact with you to keep you informed every step of the way. We also enjoyed the superior product, Phantom Screens. The installer was courteous, efficient and clean with his work! Highly recommend!

Love my windows! The design Windows and door team were amazing. Would definitely recommend to anyone looking to upgrade their home.

We were getting quotes for new windows and a patio door From a couple different companies.and I actually had one company I had to call 8 different numbers just to reschedule my appointment. Well I canceled it when I finally got to someone. I requested a quote from Design Windows and doors I immediately got a call from Bill about getting me a quote. He came out did the measurements we went over what we wanted. He even made some suggestion we didn’t even think to ask. After the order was in and the manufacturing started my project manager Martha reached out to me every week if not twice a week just touching base letting me know where we are on the project and if I needed any help or had any questions. We did add to the order which she quickly made the adjustments and kept the project on track. We are so happy with the look of the new windows and the amazing quality. It was so refreshing knowing a business cares about their customers and giving excellent customer service. I have already recommended them to several family members and friends.

Great staff! Installation was A+ and the windows look amazing! I highly recommend using them 5 plus stars

Best decision we have made for our home thus far!
We love our windows and side door. They were very professional and always on time. And the work they did is super clean. Four windows and one door installed in 6 hours! And no mess! Will be using them for all our windows.

My new windows look amazing! Design Windows and Doors Inc. Have a clean and professional staff. I'm very satisfied with the qualify of the windows and the their price.

I highly recommend this company for all your future designs and repairs.my sliding door was installed in under 3 hours, their crew was on time a d ready to work.they were very professional, no stucco or dry wall damage. I cant say enough on how clean and tidy they were no scratches on my hard wood floor or dirty walls or anything.nothing bad to say about them at all.

Great experience with Design Windows and Doors. Their staff, from the Home Show vendors to salesperson to administrative staff to installation technicians, are all professional, knowledgeable, and very friendly. I purchased a dual pane garden window for the kitchen and could not be happier with it. I highly recommend them.

I couldn't be happier with my window & door replacements! Great crew and staff. Overall 100% satisfied! Thank You.

Little did I know I was going to be stalked. I called Design Windows and Doors and decided not to use them. Ever since then, they have called me EVERY SINGLE DAY FOR MONTHS! They have called and called me and won't stop! Beware these people they are pathological and stalk you. You'll have to change your number to get them to leave you alone. DON'T CALL THEM OR THEY WILL STALK YOU!

Had 21 MIlgard windows installed by Design windows & Doors, guys were on time and installed these windows in 6 hours great job, nice guys left house cleaner then when they showed up, would highly recommend Design Windows & Doors Great experience Thanks

Got our new door installed on the 29th of December. Very happy with the installation crew and their tidyness and speed of installation. Salespeople were nice and informative and gave us a great price. Would recommend them to my family and friends.

From our first appointment with your consultant Bill Grube to Martha in the office who walked through the entire process with us to the installation with Genesis and Jared we couldn't have asked for more. Bill even came out and gave a presentation for our Board of Directors about retrofit windows and now we have options as a community. Great company to work with. So professional in every aspect.you won't be disappointed.

Thank you Design Windows & Doors for another positive experience. DW&D’s has installed three sets of windows for us. Everything beginning with the selection of the windows and doors to the installation was first-class. Highly recommend this company.

Really glad we did business here. Good product, price and installation. Knowledgeable sales person took good care of us. We have no regrets
