Loft Insulation Specialists Covering Penarth

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 Penarth, including Cogan, Llandough, Penarth Marina, Victoria Square, Sully and Dinas Powys.

Penarth's large Victorian and Edwardian houses have big roof spaces that leak heat, and their clifftop position catches the wind off the Channel.

Penarth is about 50 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 Penarth: FAQs

Do you cover all of Penarth?

Yes — we cover the whole of Penarth and the surrounding villages, including Cogan, Llandough, Penarth Marina, Victoria Square, Sully and Dinas Powys.

How much does loft insulation cost in Penarth?

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 Penarth homes have 100mm or less, which is why a top-up often makes such a noticeable difference.
