"Mike was a lifesaver. Previous contractor walked off the job after ripping up the tile floor in my bathroom, claiming I needed to get the whole subflooring redone. My wife and I were in a bind because we had already removed the toilet and vanity (and it is the only bathroom in our house). Found Pine Tree Flooring on Angie's List, and Mike came out that very evening. He assessed the problem as not nearly so severe, and was able to complete the entire installation in just a few days. He and his workers were punctual, polite, and professional. Mike even helped to install our new toilet and vanity once the flooring was finished. I wouldn't hesitate to call him again."

"Shaun and his assistant were friendly and professional. We had a slight mix-up with timing but communication on the day of install was good and everything was taken care of. It was a great experience, we discussed other possible jobs at the end of the install."

"This was a big job that was part of a whole-house renovation. JA Drywall installed framing and drywall throughout my second floor (three bedrooms + hallway) that had experienced a fair amount of water damage as the result of a leaky roof. Juan and Joshua were great coordinating the project--super quick response time for a walk-through & estimate. And the crew were great---super nice guys who did a great job. (One of them even lent me a tool to help with a project I was working on in the kitchen!) Both my carpenter and painters were impressed with their work. I would rehire &/or recommend them in a heartbeat."

"Trevor came out with another guy (I forgot his name) and they were awesome! Any time I had a question. I can call them and get a quick response. I didn’t fully understand how my unit worked at first so I had to contact Bill (who is just as awesome) Trevor came right over. I’m loving my unit and will recommend them to anyone who need a new unit or their old unit fixed. I was able to trust them in my house without me being there and they clean up behind themselves. I had some other work done at my home by other companies and Universal Air is by far THE BEST!!! Thankful so much guys!! People. You’re on the right path of no headaches when dealing with Universal Air. I can’t express enough how polite and clean they are and their work matches."

"A representative called immediately. Someone made arrangements to come and diagnose the problem promptly, and got the work done within the next couple of days. Excellent service, prompt, and friendly."

"Alpha & Omega PMR did a good job with repairing my window I was having a draft come thru my front window and because the window balance was off he was able to rebalance the window and repair the spring loads as well as replace the locks and clips to repair it, saved me a headache of replacing the entire window frame. I highly recommend his services, legit and honest work. 10/10"

"Dan was great from start to finish. Being new home owners he walked us through the options available to us and found the best door for our needs and budget. Dan’s work was top of the line. He took great care when installing the door and everything turned out even better than expected. We look forward to having Dan help us again, when it’s time for our next home project!"
