"They were fast, efficient and effective.  All the right tools and skills.  A wonderful cheerful attitude.  The job they did was amazing!  The windows were like clear crystal.  You could almost put your hand through them.  Perfect!  Worked on a Saturday to get the home ready for architectural photos.  Two agile team members began early and finished within the day.   I would use them again in a heartbeat. <br />"

"They build all of their products custom to each opening. The installer came out and measured before I ordered. They came back out after the guards were delivered to install them. They custom designed a set to match my doors. The finished product is beautiful."

"The entire process went smoothly. The reservation went quickly, once we paid an extra $200 to reduce the pickup window to 3 days. The pickup and drop off process also went well. The car was returned in the same condition we left it. We would recommend using United Freight."

"These are different times with the virus. Because of my age I have to be careful. And so it's important to say that DMC followed all protocols without prompting, with masking, social distancing, and was even careful to contact no surfaces unnecessarily, and so was very professional and courteous with these not-so-pleasant issues. But to back up a bit, knowledgeable diagnosis of the problem began with the initial phone call. Experience counts, and the diagnosis was confirmed quickly upon arrival. Tests were done in front of me, and the problem explained clearly. I had called in early morning, and was scheduled in, despite three other jobs planned for Les (the tech) ahead of mine. He arrived in the first fifteen minutes of his predicted time-window, and his work, despite challenges described below, was as efficient as his predicted arrival, The job was complicated first by the furnace not being installed in its most conventional and accessible way, and second, even though he would have made the replacement with a universal motor to save cost, the particular furnace required its specific part only. This said, he knew exactly where the nearest distributor was, and retrieved the necessary replacement quickly. Despite the difficulty of the disassemble/installation and having to retrieve and use only the specific replacement, his price point was well within researched averages, This was a great comfort, and another reason to leave this highest possible review for a top-flight service company. Based on such, DMC will be the first company I call for any further a/c or heating concerns. Thanks!"

"Excellent. Got our bid from Brian to replace the electrical panel (as ours was a serious safety issue) and do several fixes, small installs of electric throughout house. The bid was spot on and very fair in price (I had done my homework). His crew arrived on time, worked quickly and efficiently, cleaned up after themselves and stayed after normal business hours to get the lengthy task of upgrading the panel done. When the inspector reviewed the work, said it was on par with top notch commercial install and to the standards he would do in his own home. I'll be using Brian again (hopefully) soon when I complete our remodel."
