Insulated sectional garage doors: what matters for Feltham garages
How much difference do seals make?
Panels are only half the story. A good door has a flexible bottom seal that follows uneven floors, brush or rubber side seals, a head seal and finger-safe joints with gaskets between sections. A badly sealed insulated door can lose more heat round the edges than through the panels, so seals are checked and set on fitting day.
Is it worth it on a detached garage?
On a detached garage used only for a car, a standard double-skin door is usually enough. If you keep tools, bikes, a freezer or stock in there, or you use it as a workspace, the warmer, drier conditions are worth the extra cost.
Options and upgrades for Feltham homes
- Any finishRibbed, flush, cassette, woodgrain and coloured finishes are all available with insulated panels.
- Seals all roundBottom, side and head seals, plus gaskets between sections.
- Panel thicknessTypically 40 to 42 mm double-skin, or thicker thermally broken panels on premium ranges.
- Window insertsAdd glazed inserts for daylight; they slightly reduce thermal performance.
Guide price for an insulated sectional door in Feltham
Guide price: £2,095–£3,495 inc VAT. That covers the door, fitting, removal of a standard old door and VAT; the fixed price follows the free survey.
Our free survey checks the opening, headroom above it, room either side for the tracks, garage depth and where an operator will be powered from.
Do you need permission in Feltham?
The planning authority for Feltham is the local London borough council. A replacement garage door is usually outside planning control, but it is worth a quick check where conditions apply.
In England you can usually replace a garage door without planning permission. Check first if the house is listed, sits in a conservation area or Article 4 area, or was built with planning conditions covering the garage.

Questions from Feltham customers
Can I add insulation to my existing up-and-over door?
Insulation kits exist for up-and-over doors, but they add weight that the springs were not designed for and seldom seal well. Replacing with an insulated sectional door is the reliable route.
Can an insulated door be fitted to an older garage?
Usually, yes. The opening needs to be sound and square enough to fix to, with enough headroom above the opening and room either side for the tracks. The survey checks all three.
Which parts of Feltham do you cover?
We cover Feltham across postcode districts TW3, TW4, TW6, TW12, TW13, TW14, along with nearby Hounslow, Southall and Hayes. Dates are agreed when you book.
Will the local London borough council need to approve my new garage door?
Usually not. Replacing a garage door, including with an electric sectional door, does not normally need planning permission in England unless the house is listed, in a conservation area or Article 4 area, or has planning conditions affecting the garage. If in doubt, ask the local London borough council before ordering.
