Loft Insulation Specialists Covering Llanelli

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 Llanelli, including Felinfoel, Dafen, Bynea, Pwll, Llwynhendy and Burry Port.

Llanelli's terraced streets and coastal estates catch the wet westerly weather off the Loughor estuary, so good loft insulation and ventilation really help with warmth and damp.

Llanelli is about 1 hour 25 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 Llanelli: FAQs

Do you cover all of Llanelli?

Yes — we cover the whole of Llanelli and the surrounding villages, including Felinfoel, Dafen, Bynea, Pwll, Llwynhendy and Burry Port.

How much does loft insulation cost in Llanelli?

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