Loft Insulation in Filton
Filton sits on Bristol's northern edge and has long been tied to aviation, from the aircraft works to the old airfield that is now being built over as Brabazon. We fit loft insulation in Filton across the interwar semis, post-war homes and the newest houses on the former airfield.
Our team travels from Cardiff over the Prince of Wales Bridge on the M4 and round onto the M5, so north Bristol is a manageable run. Surveys are free, quotes usually follow within 24 hours, and most lofts are finished in a day.

From interwar semis to Brabazon new builds
Much of Filton's older housing went up between the wars and in the years after 1945, as the aircraft industry grew and needed workers living nearby. That means plenty of brick semis and short terraces with hipped or gabled tiled roofs, alongside post-war housing built in the same spirit.
Those older lofts tend to be roomy, with traditional cut-timber roofs rather than trusses. They often hold a patchwork of insulation: a strip of old fibreglass, some newer roll laid by a previous owner, and bare areas around the tank and hatch.
The new homes on the airfield are a different case. They're built to current standards with deep insulation from day one, so the question there is usually how to use the loft for storage without spoiling what's already in it.
What Filton homes usually need

Loft Insulation in Filton
Filton's interwar and post-war semis commonly have patchy, flattened insulation, and evening it out to 270mm with Knauf Earthwool closes the gaps.

Loft Boarding in Filton
New-build owners at Brabazon who want storage need boards raised on loft legs, because laying them straight onto the joists would squash insulation that's already doing its job.

Spray Foam Removal in Filton
Homes changing hands in north Bristol get surveyed closely and spray foam on the roof underside is often flagged, so we remove it, clean the timbers and re-insulate correctly.
Working in Filton and north Bristol
The A38 through Filton gets busy at peak times, so we aim to arrive early and get materials unloaded quickly. Most of the older houses have driveways or reasonably wide roads, while parking on the newer streets can be tighter, and we'll agree where to stop when we book. Interwar semis usually have a decent-sized hatch in the landing ceiling, which makes getting materials up into the loft simple and often leaves room for a ladder later.
If a survey has picked up spray foam in your loft, our spray foam removal guide covers what the job involves. For storage in a newer home, see how we fit raised loft boarding.
Loft insulation in Filton: FAQs
Can I board my new-build loft at Brabazon?
In most cases, yes, but it needs doing properly. New homes have deep insulation laid between and over the joists, and boards laid straight on top would crush it. We fit loft legs to lift the boards clear so the insulation keeps its full depth. We check the truss layout first too, because trussed roofs must never be cut or altered.
We're selling our Filton house and the survey mentioned spray foam. What now?
It's common for surveyors to flag spray foam, because it can hide the condition of the roof timbers. We can inspect the loft and quote for removing the foam, cleaning the rafters and battens, and fitting suitable insulation instead. Once that's done, the roof can be inspected properly, which is usually what a buyer's lender wants.
Do you travel from Cardiff to Filton?
Yes. Our team crosses the Prince of Wales Bridge and heads into north Bristol on the motorway, so Filton is a manageable trip. We agree a survey date with you and send a written quote after the visit, usually within 24 hours.
Our 1930s semi has a water tank in the loft. Does that matter?
It just needs handling properly. Once the loft floor is insulated, the roof space gets colder, so we lag the pipes and insulate around and over the tank. We leave the patch directly underneath it uninsulated so a little warmth from the house helps stop it freezing.
