Draught-proofing in Gorseinon

Draught-proofing in Gorseinon starts with a free survey of the property, then a written result and a fixed price before any work is booked. Draught-proofing seals the gaps that let warm air out and cold air in, around doors, windows, letterboxes, loft hatches and skirting boards, while leaving planned ventilation alone.

In Gorseinon homes this is often done on the same visit as a cavity fill, which saves a second trip. Where a Gorseinon home also has empty cavity walls, we can survey those at the same time.
