Garage Door Repair & Installation in Duncan
Residential garage door repairs, new doors and openers across the Cowichan Valley, with repairs handled same-day, subject to technician availability.

Duncan sits at the centre of the Cowichan Valley, and our technicians look after homeowners across the valley. There is no travel fee, and residential repairs are handled the same day, subject to technician availability. Commercial door needs in the Cowichan Valley are handled by our sister location, Tedford Garage Doors Victoria.
Because Duncan is the hub for the whole valley, one day of calls often covers several stops. A tech at a stuck door near Cowichan Commons may carry on to Maple Bay, out to Cowichan Bay or west toward Lake Cowichan. Older homes in the downtown core, newer subdivisions around Quamichan Lake and acreages out in Glenora all get the same stocked truck and the same written quote before any work starts.

Does Tedford charge extra to travel to Duncan or the Cowichan Valley?
No, there is no travel fee in Duncan. Duncan and the wider Cowichan Valley, including Cowichan Bay, Lake Cowichan and Westholme, all sit within the area covered by Tedford's "No travel fee inside our service area" policy.
At a Duncan address, the technician inspects the door system, sets out the fix and its price in writing, and waits for your go-ahead before starting. Like every Tedford price, the approved amount has GST added.
Does Tedford serve Duncan, and how soon can a technician come?
Yes, Tedford serves Duncan homeowners, and Cowichan Valley repair calls are handled same-day, subject to technician availability. Dispatch confirms your arrival window once the visit is booked, rather than leaving you guessing.
Describing the symptom when you book, such as a bang from the springs or a door stuck halfway, helps the technician arrive with the right parts. Common parts already ride on the truck, so a Duncan door can often be fixed in one trip.
Does the summer heat in the Cowichan Valley affect garage doors?
Yes, the Cowichan Valley's warm, dry summers, which often run a few degrees hotter than the coast, make a garage door in Duncan age faster, especially a dark door facing south or west. Strong sun fades paint, dries out rubber seals and can turn an uninsulated garage into an oven that heats the rooms beside it.
Low evening sun shining straight into an opener's safety sensor can also make the door reverse for no obvious reason; shading the sensor usually fixes it. An insulated door in a lighter colour keeps the garage noticeably cooler, and Tedford can replace dried-out weather seals before the autumn rain arrives.
My garage door at Lake Cowichan freezes to the ground in winter. How should I free it?
Melt the ice along the bottom seal to release a garage door frozen to a Lake Cowichan floor; running the opener can strip gears or tear the seal. Warm air from a hair dryer, or careful work with a plastic scraper, releases the seal without damaging it.
To stop it recurring, sweep slush and water away from the door before a cold night and keep the rubber seal supple with a silicone spray. A flattened or split bottom seal lets water pool and freeze, so replacing it is often the real fix; seals are a standard Tedford repair anywhere in the Cowichan Valley.
How can I tell if a garage door spring has broken at my Duncan home?
A broken garage door spring at a Duncan home usually announces itself with a loud bang, followed by a door that won't lift. Sometimes the door rises a few centimetres before the opener gives up. Look at the spring above the door: a visible gap in the coil means it has snapped. Side-mounted extension springs may hang loose or look stretched instead.
Don't keep pressing the button or try to lift the door, because without the spring the opener and your back take the full weight. Call Tedford with what you see; a vehicle trapped in the garage is prioritised, and many Duncan spring repairs are completed on the first visit.
Can I choose a new garage door at home in Duncan?
Yes, Tedford measures your Duncan home and gives a free estimate on a new garage door there, so you can choose it without leaving home. The technician checks the opening, headroom, side room and your current opener, then walks you through Clopay, Amarr, Garaga, Steelcraft and Northwest Door styles, colours and insulation levels.
Once you approve the written quote, the door is ordered, typically arriving in 1–4 weeks, and an install date is booked. Tedford's $100 off new-door offer applies to your Duncan install too.
I'm selling my house in Duncan. Is it worth having the garage door looked at first?
Yes, a garage door check before listing a Duncan house is worthwhile, because buyers' home inspectors routinely test the auto-reverse. A door that doesn't reverse when it meets an obstruction gets flagged in their report. A failed auto-reverse, a noisy opener or a visibly rusted spring can turn into a negotiating point late in a sale.
Book a service visit before the listing goes up: the technician works through Tedford's 34-point safety check to find what may be wrong, then gives you repair options in writing so you can decide what to fix.
Does Tedford cover the rest of the Cowichan Valley around Duncan, including commercial doors?
Tedford covers homeowners in Duncan and the surrounding Cowichan Valley communities on its service list: Cowichan Bay, Lake Cowichan and Westholme, plus Chemainus and Ladysmith to the north. Commercial garage doors in the valley are looked after by Tedford Garage Doors Victoria, so business owners should contact that location instead.
Rural homes around Duncan often have a detached garage alongside the house door, so mention every residential door that needs attention when you call and Tedford can plan the visit around them.
