Commercial Garage Doors

Mostly the parts you cannot see. A commercial door is built for cycles: the springs are rated for far more openings, the hardware is a heavier gauge, the track is stronger, and the rollers and hinges are sized for continuous use. Panels are frequently thicker and the finishes tougher. Two doors can look almost identical in a photograph and be five years apart in service life when a business uses them — which is exactly why a commercial door quoted against a residential price looks expensive until the third spring failure.

Our overhead work is commercial and industrial: service bays, fleet garages, fire halls, shops, restaurants, warehouses and plants. That focus is the reason the specification advice on this page is worth anything — the crews, the parts stock and the after-hours rates are all built around commercial openings. If you have a house with a garage door, we can do it too — and it costs much less than a commercial garage door.

The range is wide enough that a single figure would mislead: a small single-skin door in an unheated shop and a large insulated door with vision panels, a powered operator and a safety package are different orders of number. What moves it most is size, panel construction, spring rating and whether it is powered. We measure and send a firm itemised quote at no charge — and we will tell you when the less expensive specification is genuinely the right one for how the door is used.

Count openings, not days. A car dealership service bay might cycle a door forty times a day; a fire hall a handful; a busy body shop a hundred or more. A standard spring is commonly rated around 10,000 cycles, so at forty a day that is well under a year, and at a handful a day it is many years. This is the single most useful number you can give us, and almost no quote request includes it.

If the space behind it is heated at all, yes — including buildings heated only to protect equipment or pipework. An insulated sandwich panel is the best thermal performance available in an overhead door, and it also makes the door quieter and stiffer, which matters on a wide opening. On a genuinely unheated shop or covered yard, a single-skin panel is honest value.

Yes, and on a sectional door it is straightforward — a row of vision panels in one section is often all the daylight an opening needs. A full aluminum-and-glass door is the other end of that scale, used on showrooms, restaurants that open onto a patio, and service bays where visibility into the shop is part of the point. Glazed doors insulate less well, so the trade-off is light against envelope.

Almost certainly the spring was rated for the door rather than for the usage. Spring life is measured in cycles, and a door used a hundred times a day burns through a standard spring in months regardless of how good the door is. The fix is a high-cycle spring, matched to the door's weight and drum — more expensive to buy and dramatically less expensive to own on a busy opening. It is also worth checking whether the door is out of balance, because that shortens everything.

Plan on 2–4 weeks to manufacture once the opening is measured, then 1–2 weeks to schedule the crew — roughly 3–6 weeks in total, because the door is made to your opening. A like-for-like replacement into a sound opening is typically a day, with the bay back in use the same day. Repairs are different: cables, rollers and door hardware are carried on the trucks, and a failed operator is replaced rather than rebuilt. Springs are the exception — each one is wound to its own door, which takes 1–2 days, so a spring replacement is two visits.

Usually, yes — factory finishes cover a wide range and custom colours are available on most commercial panels, which matters for dealerships, franchises and anywhere the door faces the street. Say so at the quote stage rather than afterwards: a custom finish is a manufacturing decision, and retrofitting it means painting a door that was never meant to be painted.
