"Elvin is great. He fixed my wood double front doors and applied paint that I had picked out, as well as new handles/lock. He took his time, was very polite, and made sure everything was in order before in left. My front doors look amazing. Will be hiring him again for more work around the house. Also, his pricing was very reasonable and on point for the amount of repair and painting work he did."

"Was very nervous hiring someone to do my roof. I’ve had bad experiences in the past. The salesman Nick met me at my home. Gave me in full detail a step by step breakdown of how the project was going to unfold. I just got my deck done a month prior. He assured me that everything would be covered, and the clean up would be thorough. On the day of my installation, not only was property protected. The owners of the company Zak, and Rich came out personally to bring insulation board to cover my railings of my new deck. I was very impressed with that, the detail and follow through with everyone involved with the project. My wife and I are planning to get the roof done on our rental property this year, and I know I only need to make one call to get the job done right. I highly recommend A1 Home Improvement for any outdoor project you have."
