Loft Insulation Specialists Covering Portishead

Around a quarter of the heat in a typical home escapes through the roof. If your loft has old, thin or flattened insulation, you're paying to heat the sky. We insulate lofts right across Portishead, including Portishead Marina, Redcliffe Bay, West Hill, Capenor and Port Marine.

Portishead mixes older stone homes on the hillside with newer marina developments, and many of the older properties still have thin or settled insulation from decades ago.

Portishead is about 20 minutes from our Bristol base, so we can usually get out for a free survey within a few days and complete most installations in a single day.

Loft Insulation in Portishead: FAQs

Do you cover all of Portishead?

Yes — we cover the whole of Portishead and the surrounding villages, including Portishead Marina, Redcliffe Bay, West Hill, Capenor and Port Marine.

How much does loft insulation cost in Portishead?

It depends on the size of your loft, what's already up there and which material suits it best. We'll give you a fixed quote after a free survey, so there are no surprises.

How long does it take?

A standard loft insulation job is usually finished in one day. Adding boarding or treating mould can add a little time, and we'll tell you upfront.

How much insulation do I need?

Current guidance is 270mm of mineral wool. Many older Portishead homes have 100mm or less, which is why a top-up often makes such a noticeable difference.
