Only complaint is they didn't seal the windows in the corners with caulk very well

5.0 Kaveh A. Englewood, CO

JDI did an excellent job on my windows, I'd gotten pressured into a contract with Champion windows and Rex acted quickly to educated me about industry practices and ultimately helped me get much more for my money that I would have otherwise gotten. Rex's crew was great to work with and did a great job, everything went as expected, and I love my new windows. Would highly recommend JDI windows and have already recommended them to friends and family.

5.0 Chris C. Littleton, CO

JDI Windows was outstanding! I give this Company a 5 star rating for quality, service, professionalism, craftsmanship, and service. Look no further than this local Colorado Company that installs great Amerimax windows at a very affordable price!

5.0 Daniel and mary B. Centennial, CO

If we could give a 10-star rating we would. We recently replaced 12 windows with JDI and have nothing but the highest recommendation for them. Rex (the owner) is great; he's very personable, professional, knowledgeable and most importantly no high pressure sales pitch, which we greatly appreciated. The price was very competitive and we really liked that NO down payment/upfront money was required until the installation was complete. We had 4 bids and JDI was the only company that offers this. Darrin Sr. (installer) and his crew (Darrin Jr. and Rob) came out for the installation; they are professional, courteous, meticulous about their work and really nice guys. Darrin Sr. is great at communicating (scheduling, expectations, etc.). They were on time and worked continuously until the entire job was completed (1 ½ days). As each window was installed they cleaned the windows, vacuumed, cleaned up all construction material and reinstalled our blinds. Overall JDI service is superb and we highly recommend them. We are more than pleased and love the Amerimax windows.

5.0 Sharon L. Aurora, CO

We had Windows and sliding doors replaced. Rex gave us a very detailed estimate and there were no hidden charges! We had several estimates and JDI was by far the best. The installation was very easy and the crew was great. We would recommend JDI windows

5.0 Kimberly C. Denver, CO

Very clean, honest and quick install. I am in love with my new windows and would absolutely recommend!! They are extremely personable as well, Thank you for my new windows!!!!

4.0 Robert L. Arvada, CO

Excellent review of needs and window type. Good communication with installer for measurement and ordering. Amerimax windows were manufactured quickly as I requested a short time schedule. The only down side came when I received a call from the installer for a delivery/ installation date. I rescheduled several appointments to be available and the morning of installation was advised of a delay due to manufacturerâ  s delivery of windows. Later advised shipment not in in time to do that day. Rescheduled for next day, again rescheduled some of my appointments. Advised by installer shipment was again late.. a few hours later was advised they actually couldnâ  t find the shipment. Later it was â  foundâ  and could they install two days later on a Saturday morning. I could not change plans for weekend and asked to install on Monday. Installer said he had another install commitment for Monday and Tuesday and couldnâ  t install until the following Wednesday. It would have been nice if he had shifted his time commitment since I had changed mine twice already. I was also not impressed with the way Rex, the sales person, tried to spin the delays into a positive about how much Iâ  ll like the windows. The actual install went well and looks great. The screens are a little â  wavyâ  and not tight in their frames. So I would say the quality of the product is good but not excellent. The quality of the install was excellent. The delays and the way they were handled was not good.

4.5 Broomfield, CO

These guys were great! I had 3 companies quote and JDI had the best reviews and so did Ameristar. The sales guys brought a demo window to show me the features and understood that I was on a budget. The window manufacturer also has outstanding reviews and has been in business a long time. I'm in Denver and like the fact that the windows are made in Colorado so you won't get any gas leaks from the window from pressure differentials that you would get from a window made at sea level. As for the install, the crew was very nice (although late my pet-peeve). I was a mess because I didn't realize how quickly the windows would be made so I had to cancel a lot of plans. I appreciate the crew trying to make everything perfect and fixing items that got damaged (I think it actually looks better with the fixes). And I appreciate them paying attention to detail (big browny points) So just be prepared that this won't be as smooth as you think. Unfortunately, the sales guy tells people it takes 1 day for install, sorry that's not quite true. I watched my neighbors house take a week. My house took 2-3 days and I had 9 windows, but if you want it done right and to look good then just let the crew do the job. I also like that the install crew came back the 3rd day and did a walk through with me and did some more touch up before I wrote out the check. I highly recommend them! These windows look fantastic and its so quiet now. And the install crew has great customer service and very eager to please.

5.0 Wheat Ridge, CO

These guys cleaned up during the install and left the place cleaner than when they arrived. The windows are great. The install is great. All is right with the world after our new window install!

5.0 Terrence F. Littleton, CO

Our home had the original windows which were not very sound proof or insulating. We gathered three bids and JDI's bid using Amerimax Craftsman Portrait windows was the best value. Last week, we had 25 windows replaced and were pleased with the quality of work done by JDI's crew who were both professional and polite. We immediately noticed a significant decrease in outside sound and are looking forward to a warmer home. In our opinion, it's well worth getting a quote from JDI.
