Correct product correct application The product that I ordered was exactly as described and fit my application.

Continuous door hinge Continuous door hinge. I ordered a continuous door hinge to replace the three hinge design for an exterior door at a customers site. Everything arrived on time and was exactly what I needed.

Windows good; installation fair Generally, the windows and installation were completed as expected with only a few minor exceptions. The time to get the windows from ordering to receipt was over 4 months, but it was during the COVID outbreak so it was okay. The windows were installed by a separate contractor who did the installation well, but they were a bit messy and disorganized. We had to touch up their touch up painting. They used our vacuum cleaner because theirs weren't working so good. If you use this company, try to get a hard date for delivery or no later than date on the contract. When they install, make them use dust screens to prevent tiny aluminum shavings from being blown all over in your house. Have a pint of exterior trim paint ready for them to touch up. You tell them which windows to change the next day so you can prep just that portion of your house. 20 windows took 4 days. 1 screen was warped, but delivered a replacement the next day.

Long lead time Long lead time, 3-4 weeks. Will not ship to a residential home. If I would have known these two things in advance I would not have ordered from them...

Great service, great price, great company! Being a NYC commercial real estate developer we are constantly in need of doors & hardware for our buildings. After dealing with many companies over the past 10 years none have provided us with the reliability, quality, and professionalism that QDH has. We have purchased over 5,000 doors from them in the past 2 years and we now use them as our sole supplier. It's always a very smooth process getting orders filled. They are fast, reliable, professional & competitively priced. I would suggest trying them out, you will not be disappointed. Ask for Jeff Jr... His customer service is unmatched in this industry!
