"Brad was extremely knowledgeable about the product and work required for installation. He guided me to the right hoop for my property, and I felt very confident we made the right choice after the first conversation. The work is as done timely, professionally and turned out great"

"Our second time using united and it was great."

"Tim was great to work with. He and the crew arrived on time and were very professional. They transferred the heating oil to barrels, removed the old tank, installed the new tank, replaced the fuel line to the furnace, relocated the filter to a more accessible location. and then transferred the oil back. Immaculate clean up. I wouldn't hesitate to recommend this company."

"The technician 'Robi Chin' arrived on time and I demonstrated my problem and he said it was minor problem and he set to work. He finished in about 15 minutes and he relined the tracks and lubricated both tracks & springs. The door ( Which is a large door 8'X10' and his work was flawless. It works better now then when new. I highly recommend this company and intend to have them install a power lift motor package shortly. <br />"

"Custom Pull Out Shelves added shelves to three of my lower cabinets and my pantry. They did a wonderful job! The shelves are beautiful, work perfectly and add so much additional space to my "less than spacious" kitchen! Installation was quick, maybe 3 hours. The Installers were careful with my floors (covered them with pads) and counters (never even put as much as a screwdriver on them) and made virtually no mess at all. I highly recommend this family-owned company for both quality and competitive pricing. I'm a totally satisfied customer."

"<p>It went very well. They were willing to answer my questions.  One question I asked was if I should have the humidifier replaced and they indicated it wasn?t needed at the time.  I felt they were honest with this answer. I couldn?t have asked anything more.  Their price was much less than others. They cleaned up everything and installation was fine.  </p> <p> </p>"

"Cody and Kyle Mikkola came to install a new sump pump in our home recently. They were very communicative about being a little late because they had to stop for parts. When they arrived, they were extremely professional and courteous and did a very thorough job. Their service was top-notch. They discussed the project with us thoroughly beforehand and were diligent about cleanup and removal. We are extremely happy with the work that they did and would not hesitate to call them again should we require future projects. Thank you Cody and Kyle!"

"We didn't order the work to be done (at least not yet). (Opted instead to try to get new fence installed by fencing contractors). <br />"
