Homeowner Testimonials

Some of our satisfied customers


Professional & Courteous

As a woman, I always expect that repair guys will try to take advantage of me. Adam was an exception. He was professional, courteous and didn’t try to charge me for extra services that I didn’t need. I highly recommend Adam.

Very satisfied!

Adam is a great guy. He has helped me several times with gate issues in my home and has always been professional, timely and reasonable with pricing.

Easy to work with

Adam is great, super easy to work with! Highly recommend Castle Improvements for your garage door needs. He even fixed my old door so that I could use it while waiting for my new doors to arrive.

Quality & Service

Very pleased with quality of service and price as well. My garage door spring had broken when i was in a hurry to get to work. I called Castle Improvements because one of my neighbors recently got new garage doors from them and was extremely happy with the service. Adam arrived quickly. He replaced the spring at a very reasonable price and was working very fast. Thanks a lot!

Letter of Appreciation

It is not that I take the time to write a letter of appreciation to a contractor! However, your service was so excellent that I could not let it pass without that extra thank you. The springs holding my garage door broke on Sunday. I placed a call to your office and left a voice mail on Sunday. Monday morning, Presidents Day, you called me back first thing in the morning, and scheduled the repair for the next day between 8:00 and 10:00 a.m. On Tuesday morning at 8:30 a.m. your technician was at my home, the spring was repaired by 9:00 a.m. at the price you quoted in the beginning. Unfortunately in this day and age it seems to be rare commodity that a service business does what it says it is going to do when it says its going to do it. Your truly the exception. Thank you and your technician for your promptness and service.

Very fast and professional

My experience with Castle was the most professional experience i have ever had. I own several properties and have gone through several other companies, Castle was exceptional. The quality, speed, and price they showed gave me the urge to tell my friends.
