- If your control box or receiver can't work with the new motor, a matching one is quoted before fitting.

Roller garage door motor replacement in Dumbarton: questions
Will you fix the door on the first visit?
A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.
Can I message you a photo of my garage in Dumbarton?
Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Dumbarton. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.
Do you repair roller doors you did not fit in Dumbarton?
Yes. We repair roller garage doors of any make in Dumbarton and across G82, where parts are available. If a part is no longer made, we tell you what will fit instead, or price a replacement door if that is the better option.
Do you charge more for Dumbarton than other towns in Dunbartonshire and Argyll?
No. Guide prices are the same for Dumbarton as for anywhere else we cover in Dunbartonshire and Argyll. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.
Can you replace the motor on any make of roller door?
We replace tubular motors on electric roller garage doors of any make, provided a compatible motor is available for the barrel size and curtain weight. Send us details of the control box and the door size and we'll confirm before booking. If a matching motor isn't available, we'll explain the options, including a new control box or a new door.
Why does my roller door motor hum but not move?
A humming motor that doesn't turn the barrel can mean the motor has failed, but it can also point to an obstruction, a curtain jammed in the guides or a fault in the control box. Stop pressing the button, keep clear of the door and don't force the curtain. A repair visit diagnoses the cause before any parts are quoted.
