Loft Insulation in Corsham
Corsham is a Wiltshire town built largely of Bath stone, with a High Street of old weavers' cottages and merchants' houses leading up to Corsham Court. Loft insulation in Corsham has to suit those historic buildings as well as the modern estates that have grown up around the town.
Our team travels from Cardiff along the M4 to junction 17 and down through Chippenham. It's a fair drive, so we arrange surveys in advance and send a written quote, usually within 24 hours.

Bath stone cottages to modern Corsham estates
The historic centre is a conservation area with many listed buildings, including the row of Flemish weavers' cottages on the High Street. These older stone houses have stone tile or slate roofs over irregular timbers, with low, awkward lofts and in some cases rooms built into the roof.
Pickwick and the older roads around the centre add Victorian and early twentieth-century homes, while post-war housing and more recent estates, some on former Ministry of Defence land, make up much of the rest. Those later homes have regular, accessible lofts that are simple to insulate.
In the old stone houses, moisture is the main concern. Stone and lime need to breathe, and the wrong insulation in the wrong place can trap damp in the roof. On the newer estates the opposite applies: the main job is usually topping up insulation that was laid thinly or disturbed, and keeping it at full depth if the loft is used.
What Corsham homes usually need
Loft Insulation in Corsham
Vapour-open mineral wool suits Corsham's stone houses, and on the town's newer estates a top-up to 270mm is often all that's needed.
SuperFOIL Insulation in Corsham
Cottages with rooms in the roof or very little loft height suit thin multifoil fixed to the rafters, keeping the space usable.
Loft Mould Treatment in Corsham
Old stone roofs with poor airflow can develop condensation and mould, which we treat while improving ventilation so it doesn't come back.
Conservation areas and listed homes in Corsham
Internal loft insulation doesn't usually need planning permission in a conservation area. Listed buildings are different: listed building consent can cover internal changes, so if your Corsham home is listed, speak to Wiltshire Council before work is booked. Fixing anything to historic rafters is the part most likely to need agreement. Parking on the High Street and older lanes is limited, so we'll plan it with you. Many cottages have small hatches in awkward places, so we check access early rather than discover it on the day.
Our SuperFOIL versus mineral wool guide explains which suits which roof, and our loft mould treatment page covers damp roof spaces.
Loft insulation in Corsham: FAQs
Can you insulate the loft of a listed cottage in Corsham?
Often, but check first. Listed building consent can be needed for internal work that affects a building's character. Laying mineral wool between joists is usually low-impact, while fixing anything to historic rafters needs more thought. We set out exactly what we propose so you can discuss it with Wiltshire Council's conservation officers.
Is SuperFOIL suitable for a Bath stone cottage?
It can be, particularly where a room is built into the roof and there's no space for deep wool. We look carefully at ventilation first, because stone buildings need moisture to escape. In some older roofs, mineral wool at ceiling level is the more breathable choice, and we'll say so if that's the case.
Do you cover Corsham from Cardiff?
Yes. Our team travels from Cardiff along the M4, and we cover Corsham, Pickwick and the nearby villages. Because it's a longer trip, we book surveys in advance and then schedule the work for a date that suits you. Most standard jobs are finished in a single day once we're on site.
We've got black marks on the rafters. Is it mould?
It might be. Black spotting on rafters and the underside of the roof is commonly mould caused by condensation. We confirm what it is during the survey, treat it with a fungicidal wash and then deal with the cause, which is usually blocked eaves, a bathroom fan venting into the loft, or insulation packed tight against the roof.
