"I had a water leak that damaged part of a wall. Henry and his team did a wonderful job of fixing it and making it look better than before! We will definitely be using him in the future for all of our handyman services. Thank you Henry!"

"I bought a dishwasher at Home Depot to be installed, They came out  and said they couldn't do it because I didn't have a shut off valve and one needed to be installed be for they could do the job.  I called ProServe told them what I needed. Tech came out, said I didn't need a shut off valve, the one in the laundry would be fine. He then installed the Dishwasher within 45 minutes.  I will definitely be using ProServe for any upcoming plumbing problems.   Fast, Fair, Excellent Service,

"Great experience.. .being a dad and looking for a HVAC system for my daughter I interviewed 3 high class companies and Premier was the winner on their presentation/systems/warranty.. The good news is their service and installation lived up to their presentation She had an new HVAC system within a week with great price and terms.. Their sales person followed up with us and small hiccups were taken care of promptly and efficiently. All good news and would encourage a look at their sales/service as their voice represents their actions.."

"Tom with J & R Interior Services remodeled 3 of our bathrooms and we could not be more pleased with the entire experience. Tom was affordable, reliable, prompt, hard working, professional, and did quality work. I was especially impressed with the beautiful tile work he did in the showers. He performed the work efficiently and completely. I would highly recommend J & R Interior Services especially for your bathroom projects!"

"Gerardo answered the phone right away. Was able to get to my house the next day to assist with cleaning my furnace and AC unit. I called a few other places and his costs was half the cost and he was very professional and explained what why and how so I knew exactly what I was paying for. And even recommended some tips to keep my house running its best."

"Very well. We received a fair and honest review of our current roof and have a game plan in place should it need to be replaced in the next few years. The project manager who came on site called us in the morning to give us an exact arrival time (had a one hour window previously) and the visit met our needs. I would certainly look to hire this roofing company for do the replacement when the time comes."
