CUSTOMER TESTIMONIALS

“You guys are true professionals. You’re really great to work with!”

After numerous attempts and many hours searching the Internet to find a reliable, honest and reputable door company, I discovered Capitol Fireproof Door and had the pleasure of speaking to the owner, Howard.

We ordered two custom-made Kalamein doors. These were produced with quality craftsmanship in a very timely manner. This company is truly an oasis in the desert!  Attached to this email is a picture of one of the doors installed. We will definitely be using Capitol in the near future as we only use top of the line products in our company.

Dear Howard:

I want to thank you for your patience and the several phone calls you made to get the measurements right. I wasn’t able to install the doorframe until just before the Holidays, but it was a damn near perfect fit.

I’ve already told the story to the local building supply company which had previously satisfied all my DIY needs for 31 years, and left them one of your business cards. I will send another to the other supplier that tried to help me with this project.

Hi Howard:

The door looks great. It looks so good in fact that we may leave it as is and not paint it. I have only compliments for the look and quality of the door and how it fits and closes.

I am a resident of Tiffany House in Cedarhurst, NJ. Today I had my front door of my apartment replaced by your company. I want to tell you that the two fellows that installed it did an excellent job. I do recommend you very highly for the excellent job done. Thanks.

Hi Howard:

I have just joined Benchmark Property Management and thought I should send you this welcome note. The doors at Brooklands look great! I trust all is well and look forward to working with you.

Dear Howard,

Just wanted to let you know that the “continuous hinge” repair your guys made on our entry door is fabulous! They did a quiet and efficient job of it. It blends right in with the door color and propped the door back up so it can close properly again. You saved us buying a whole new door.

Also, when your crew got the hinge on and the door upright again, they discovered they did not have to replace the threshold as expected so they left the old one in place.

Thanks and than your crew for me.

I can’t express in words how happy I am with the door, including the paint job (and I’m not just saying that because of my notarized letter). And your staff who installed the door were incredibly professional, friendly, and helpful.

Every person I dealt with at your company, have been great and I tremendously appreciate your work and would highly recommend you in the future.

Howard,

The new door looks nice in my lobby and the long window will make a difference. I had your installer take measurements for another door in the rear of the building.

Howard, the door looks great; thanks for all your help!

Howard,
Thanks for the prompt response. I continue to see why your company has been viable since 1949! Sincere customer service is always appreciated. Your guys surveyed the situation and indicated that they could remove the metal saddle and replace it with cement. The other option would be to chip off the remaining piece of concrete and for me to just paint the saddle when I paint the door. As the structural integrity of the door installation was not compromised and thus was not in question and it is more for aesthetics than anything else that I wanted it to be “made whole”, the painting solution is definitely a viable option so I opted for the latter. Once again thanks for your professionalism and to those on your team.
