Loft services in Sherborne
Much of Sherborne is built from golden Ham stone, with a large historic centre around the abbey. Lofts in those buildings call for a gentler approach than a modern estate house.
Ham stone, historic roofs and newer housing
Sherborne's centre is full of old buildings: town houses, cottages and almshouses in warm Ham stone, many of them listed, along with schools and the abbey itself. Roofs vary from stone slates and clay tiles to slate, and the timbers are often old, irregular and pegged. Ceilings below are frequently lath and plaster, and the lofts are small, steep or broken up by chimneys and dormers.
Outside the centre there are Victorian and Edwardian houses, interwar and post-war semis and bungalows, and newer estates on the edges of town. These have more regular roof spaces where a straightforward mineral wool top-up is usually all that's needed.
In the older stone buildings, the key thing is to keep the structure breathing. Solid stone walls and old roofs rely on moisture being able to escape, so we choose breathable insulation and keep ventilation routes open rather than sealing everything up. We also take our time in these lofts, laying crawl boards across old joists and working around historic timbers rather than cutting or moving them, so the roof is left exactly as we found it apart from the insulation.
Listed buildings and the conservation area
A large part of Sherborne is a conservation area, and a high number of its buildings are listed. Listed building consent can be needed for work that affects a building's character, so if your home is listed, check with Dorset Council before any changes, including altering a hatch. Insulation laid within the loft generally has little impact, but it's always better to confirm.
Parking in the historic centre can be tight, so we agree arrangements beforehand. For more on keeping old roofs dry, see our guide to loft condensation and mould, and read about our loft ladder fitting if access is a struggle.

Loft insulation in Sherborne: FAQs
Can you insulate the loft of a listed Ham stone house?
Often, yes. Laying breathable mineral wool between the joists is usually a low-impact change, but consent may be needed for some work on listed buildings, so we recommend checking with Dorset Council first. On site, we protect old lath-and-plaster ceilings, avoid sealing the roof up, and keep the existing ventilation working.
Why do you prefer mineral wool in old stone buildings?
Mineral wool lets moisture pass through it, which suits buildings with solid stone walls and older roofs that need to dry out naturally. Non-breathable materials, such as spray foam stuck to the rafters, can trap damp against old timbers. For historic homes, a breathable insulation with good ventilation is the safer approach.
