"everything was excellent! Fullerton is great. These closet doors were installed improperly when we built our house 14 years ago, and I had tried fixing them several times over the years, with no luck. Each folding door probably weighs 60 pounds or so, are very hard to work, and we had several sets that were either not working or barely working. Patrick from Fullerton came and immediately assessed what needed to be done. Patrick is very friendly, an excellent listener, and very professional, We set a time for the work, Patrick was right on time, had all of the various necessary hardware kits, and and got all the doors working perfectly. They had never worked so well before. We will definitely use Fullerton again very soon. It is really hard to find someone so skilled that will do all levels of jobs. Patrick and Fullerton are great!"

"They were good. When they came, they gave me a quote for the extra windows that I have that were not part of the program in their ad. Their pricing was average but I would say that it was not cheap. They did it quickly. What happened was that they were busy and I was busy too. They charged me $4 per panel and I had 21 windows and I would say that that was reasonable. What I did not like about them was that they did not call me and I had to call them twice or three times for them to come to this area because they work in different areas. But they came right on time when they said that they would."

"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!"

"Outstanding customer service. The service that was committed was delivered in a timely manner. United Freight kept me informed every step of the way. This is how all companies servicing customers should operate."

"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."
