Hear from our customers

“Thank you for your exceptional service. As someone with 12 years in construction and 7 years in hardware, I rarely encounter customer service with your level of expertise in door manufacturing and genuine commitment to customer care. Though I’ve only worked with HMF Express for 3 months, you’ve already made a remarkable impression.ˮ

Andrew, Customer

Fire station doors by Door Engineering

“Our new fire station’s 14 Four-Fold Doors from Door Engineering and Manufacturing exceed all expectations. They’re aesthetically pleasing, practical, easy to maintain with outstanding support, and consistently the most praised feature by community visitors to our facility.ˮ

James, Firechief

Senneca steel door frame

“Your efforts on this project have been nothing short of outstanding…HMF and everyone involved in this project deserve our salute as within just a few days you had frames on the road for us which bailed us out of a bad situation.ˮ

Jerry, Customer

“Thank you for your consistently prompt service. Getting quotes and answers in minutes rather than days or weeks makes a tremendous difference. The automated shipping confirmations are also extremely helpful. Your reliability over the years has made you a valued partner, and I look forward to our continued collaboration.ˮ

John, Customer

“I deal with a ton of vendors and I can honestly say you guys are top shelf and in this business that is not usually the norm. I appreciate all you do!ˮ

Bill, Customer
