"I liked that there was no nonsense. Their salesman was straightforward and the price was fair. We were also impressed with the installers. They installed all the windows in 1 day and they look great. I'm happy I chose them."

"Nixon showed up in a rain storm after hours and worked quickly to repair several glass/aluminum doors. He did a fine job."

"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."

"They were not able to fill our door space, and wanted us to make too many compromises"

"The process was seamless and quick. Everyone involved in the project was helpful and friendly. It was done in one afternoon and our roof looks great!"
