"They did a great job replacing and securing old drywall in our garage. They installed an electrical outlet which works perfectly but his suggestion, to make it easier, was to use BX which is not code in the area. Luckily I knew that because my parents would have gone with it unknowingly. I definitely wouldn’t hire them for carpentry work. We had a prehung front entry door put in and screen door reinstalled. We ended up having to have someone else come out and redo the job because they installed it so out of square that you could see daylight and the screen door wouldn’t close unless you pushed it with all your weight. They didn’t replace the interior trim or the piece of flooring they pulled out. They did a good job installing the peephole, mail slot and handle. Would recommend for small jobs but nothing too involved. Definitely not electric or carpentry."

"They installed an outlet for us and it worked perfectly. They were on time, very professional and did a great job."

"The contractor was professional and knowledgeable. He provided high quality customer service. He was thorough and precise with its service to our air conditioner. I will definitely call on his service again. He was the best and my air conditioner is running very well. This is why I use Angi's."

"Mike was on time, friendly, upbeat, got right to work. He put out moving pads to keep the carpet clean. He had all the parts needed to replace the outside faucet, and interior piping. Very pleased with service and well worth the money!!"

"Kevin and Brad did an amazing job! They replaced the subfloor that had been damaged by a leak from my toilet, installed new flooring, and put in a new toilet, making the bathroom look brand new. They showed up on time, stayed until the job was completely finished, and made sure everything was cleaned up before they left. Super friendly, professional, and hardworking. I highly recommend them!"

"I appreciated Diego’s help as my furnace stopped working and my home started to become cold fast. He was able to come the same day and quickly diagnose the issue then install a blower motor. He had excellent communication and is professional. I will be recommending him to my family and neighbors."
