We had a great rep measure and take care of the details to replace a sliding door that had been destroyed in a wind storm. A new one was installed and it works fantastic!! Thanks folks .

Dale Wiebe

They have been great to work with! They have a great heart and have gone the extra mile with us for sure. If it wasn’t for Diamond Doors, we would still have an open hangar.

David Carwell

I purchased my 20×14 Diamond door in 2015. The reason I went the bi-fold door due to a height issue as my ceiling would have been too low for my truck with having to put a header in for an overhead. After having this door now for 6 years I’m absolutely loving it and thankful now that this was the only Choice I had. This door seals much better than any overhead door I’ve seen. I’d buy this door again in a heartbeat.

Troy Robertson

Had a 40’x16.6’ insulated diamond door installed this summer. We absolutely looove it. We also did the optional auto lock system that allows the door to open and close with the push of a button. The door itself is really well built and seals nice in winter. No gaps for cold air or wind to whistle through. It’s made the building way more usable and and user friendly versus the four panel sliding doors I had before.

Patrick Fortier

Received door 42 wide by 12 high. Had factory support all the way. Borrowed a fork lift and hung it by myself. Called welder and hinges welded to structure. All in all, fabrication quality is professional and strong. I would definitely recommend this fabricator.

Anthony Spino

We have purchased many doors over the years from Diamond Doors and they always have great service and great products. Thanks for always taking care of us and our customers!

Joe Klassen, Capital Building Systems

Bought two doors from Diamond Doors. They were friendly and easy to work with. The doors are great. Very pleased with their product.

Don Doerkson

I have repaired and upgraded a lot of hangar door in my career, and I must say that Diamond doors are by far the best I had to work with. They are very safe to operate, sturdy, well documented. Their controller (the brain of the door) is fantastic. Not only do they have a superior product, the staff was very fast to answer my questions as well.

Our 46’ by 18’ Diamond Bi-fold Door has worked great since 2003

My 40×18 door in a heated shop opens flawlessly at any temperature in the winter.

Diamond Doors has insulation kits that come with their doors. Very nice finish. Would recommend that door to anyone who is putting up a new shop.

Nice solid product. Everything is labelled so it was easy to know where each piece was to go. Customer service was awesome! We strongly recommend this company.

Janet Pokrant

After two years of enjoying the new door, I am completely satisfied and regretting only of not having made the investment sooner! It has worked flawlessly during both winter and summer and in between. This door has extended my flying hobby by many years, not having to wrestle with a large door every time I use my airplane. Thank you for your great service.

Maurice Baril

The door works perfectly. I installed it and haven’t touched it since. I will recommend it to anyone that is looking for a door.
