Tayside Garage Doors fitted the door 12 years ago. I still remember the dodgy sales tactics and ridiculous quotes we received from two large, national companies to this day. TGD were a breathe of fresh air. So when the door stopped working and refused to be reprogramed, I didn't hesitate to call them back. An engineer was dispatched within a few days. He checked over and serviced the mechanism, but confirmed that the motorhead unit was faulty and had to be replaced. Even when returned to factory settings, it would not reinstall. I received an itemised quotation the very next day and I checked the prices of the parts on the internet to ensure they were reasonable. I liked the fact that the cost of the first visit was not added to the fitting cost of the repair. TGD group their work in to different areas on each day, which keeps their costs down. So I accepted the quotation and we agreed the date for the new part to be fitted. They arrived within the agreed window, completed the work cleanly and efficiently, and showed me how the updated unit worked. It was unfortunate that our 4 remote controls are not compatible with it, but three new ones were bundled into the price making them much more reasonable: Hormann remote controls are extortionately priced on their own. Thankfully, the door can also now be operated via Bluetooth via an app on my mobile phone. All the TGD engineers I have met have been great. I cannot recommend this company highly enough.
