Full door replacement

Repair, panel replacement or full replacement

There are three different jobs that are often confused. Panel replacement fixes one or a few damaged sections. Garage door installation covers fitting a new door, often for a new opening or a first-time fit. Full replacement, this page, is for an existing door that has reached the point where replacing sections one by one no longer makes sense.

That point is usually reached when the door is warped, rusted through in several places, badly dented across multiple sections, or so out of balance that springs, cables and the opener are all under strain. A single repair can still be the right call for a door that is otherwise sound, and that is why the door is inspected before replacement is recommended.

If only the motor has failed, see opener installation instead. If the door is sound but noisy or slow, maintenance may be enough. Replacement is the option when the door itself is the problem.

01

Full door removal

The old door, tracks and hardware are removed carefully, with the opening checked for level, squareness and any rot or damage.

02

New door fitting

The new sectional door is fitted, balanced and aligned, with springs and cables set for the weight of the new door, not the old one.

03

Opener compatibility check

The existing opener is checked against the new door weight and height. If it is not suitable, replacement options are discussed before fitting.

04

Testing and handover

The door is tested through full cycles, safety reverse is checked, and remotes and keypads are paired before the old door is removed from site.

How service works

What happens on the visit

Inspect the old door honestly

Sections, springs, cables, tracks and opener are checked together, so replacement is recommended only when repair is no longer sensible.

Agree door type and scope

Door style, insulation, size and opener compatibility are agreed in advance, with a clear estimate before work starts.

Fit, balance and test

The new door is fitted, balanced, and tested through open, close and safety reverse cycles before handover.

When should I replace a garage door instead of repairing it?

Replacement is worth discussing when several sections are damaged, the door is warped or rusted, it is badly out of balance, or repairs keep returning. A single damaged panel on an otherwise sound door is usually a panel job, not a full replacement.

Do I need a new opener with a new door?

Not always. The existing opener is checked for weight, height and safety features. If it is suitable, it can stay. If it is old, underpowered or missing safety sensors, replacement is discussed before the new door is fitted.

How long does a full garage door replacement take?

Most replacements take most of a day, including removal, fitting, balancing and testing. Timing depends on door size, opener work and whether the opening needs attention.

What happens to the old door?

The old door and hardware are removed from site as part of the job, unless you ask to keep a part. That is confirmed before work starts.
