A Cost-Saving Advantage

This feature is highly valuable when compared to a typical door with a damaged door surface. Normally with a broken door, you would need to purchase, install, and finish a new unit. With the American Master Door, LLC, you would simply replace a surface panel.

Testimonials

“We have a very private cabin in the mountains and needed a really strong door for a storage room where we could keep valuable items instead of carrying them back and forth on our trips. The master door was a great choice! We did have a break-in and the door had some surface damage, but held up as expected and kept that room from being vandalized, and items stolen. I can’t recommend these doors enough.”

– Bob R. Residential Customer

“One of our clients wanted a secure room in their house and they specified we use a Master door. Excellent doors!”

– James O. Commercial Customer

“We bought two Master doors for our home several years ago and they are wonderful! There is no comparison to the old doors we used to have, and I can’t imagine not having them now.”

– Susan K. Residential Customer

"Just completed a transaction for an Italian-made Master security door. The owner worked with me to configure the product correctly, and was very helpful throughout the process. The product needed assembly, crating and out-of-state shipping. The owner made every effort to get the best possible shipping rates/service for us.

The entire transaction was well priced and the turn around was fast - 2 weeks from order to delivery. I would definitely buy again from American Master Door (Formerly Category 5 Security Doors).

These Italian made doors are superior quality for residential and commercial level security doors. The product is superb, and they are very sturdy.

Again - do not hesitate to contact this company for their products (especially the Master door product line) because the owner is honest and helpful."
