Contrary to most opinions expressed here I have to give this company a low rating.
DGH installed my Amarr double garage door 3 years ago and it has worked well until my son, a new driver, parked our Honda CRV too far out. The spare tire, which is mounted on the tailgate, was sticking out. Consequently when the door was powered down it slammed onto the spare tire. The safety mechanism in the opener reversed the door, but not before all four panels of the garage door crumbled and buckled. The most severe damage was to the top section, close to the attachment of the opener. The entire garage door was a write off.
I was puzzled by the extent of the damage. In my previous experiences with garage doors hitting obstructions, the doors generally survive with little or no damage. I took a closer look at the damaged door and realized it was incorrectly installed. The manufacturer’s instructions clearly state that if an electric opener was to be used, a reinforcing strut must be installed along the top section, close to where the opener is attached. This point was mentioned more than once, including in bold on the cover of the instructions, underlying its importance. This would make sense, as that is the point of greatest stress. If you are not sure what I am talking about, you can go to Amarr’s website and download the installation instructions and you will see what I mean. In fact, I also went to Clopay’s website and their instructions specify the same. In my case, DGH installed the strut across the bottom panel where it is least needed. In addition, stile stiffeners that came with the door that were supposed to be installed on the top panel for further strengthening were completely left out. I believe these two omissions contributed to the extensive damage to the garage door when it hit the obstruction. Much of the force of that impact went to the un-reinforced top edge of the top section, instead of to the strut.
When I spoke to Dave at DGH he was dismissive and condescending. He kept asking me what I do for a living which I feel is completely irrelevant. He also maintained that it is correct to install the strut across the bottom panel, despite what the manufacturer’s instructions state.
Because of the above I highly discourage anyone from using DGH Doors. Even if you do not have the misfortune of closing your door onto an obstruction, the way DGH installs their doors, without any reinforcement to where the opener attaches, will lead to premature mechanical failure.
