I had a roll-up garage door badly fitted a few years ago which has been endless trouble. The motor provided was too small and failed. The hangers were not fitted symmetrically causing stress at one end of the roller and thus progressively failed. Garage Door Wizards corrected those things. All the previous faults damaged the door curtain and things began to fail again. I asked Garage Door Wizards to come in and quote for a whole new door as, amongst other inconveniences, I found myself drilling out the pop rivets of the cover so that I could get the door safely shut at at 10 o'clock at night and I was thoroughly fed up with the whole thing. Door Wizards could have sold me a whole new one but emphasised that I did not need a new door, just a new curtain. The real point of all this is that they could have very easily sold me a whole new door and thus made more money but they chose the honest route and I am impressed. They are definitely on my 'To be trusted' list.
