"We hired Elvin to repair a leaking window. Not only did he do that, but he offered to replace the screen which had been damaged by birds. He's truly an awesome guy and a top notch craftsman! We would hire him again in a second."

"Roofing its something no home owner ever wants to do, but most have to go through. I won't even lie I wasn't even planning on getting a new roof, but Dale Knocked on my door and thats where the process started. My roof did go through insurance & aside from signing paper work/paying my deductible A1 handled everything. Obviously specific details from the insurance goes to you and then given to A1. Its not a short process and there is paperwork you have to sign, but all In all it did take me about 4 to 5 months where the process was started to roof replacement. Dale handled interactions with showing my the conditions of my roof and how to go about getting it put through the insurance. The only hiccup was that I have solar panels and I did feel like they where taken down to early (almost 5 months off), but I made my concerns known and one of the Managers called me and credited me $500 bucks (100 per month) that the panels where off. They did tell me setbacks in productions and things happen, but made me happy by giving me this credit. Didn't fight me on it, and didn't make me feel like I was just an insurance check on the other end. You can trust A1 home improvement with your home. I would like to thank Dale for his work & all the others that helped me throughout one of the most stressful process there can be for a house."

"I hired Capital Construction to replace the aging roof shingles on my house. Their quote was completive with other local contractors and far less than national contractors. Their employees worked hard to make sure I was always informed on the status of the project. They took care to protect the house during the removal of the existing roof shingles. During installation of the new shingles the on-site crew responded quickly to my questions and concerns and resolved matters to my satisfaction. I would definitely hire them again."
