New Alresford's Georgian streets sit beside the watercress beds and the Test valley damp. We lift foam off historic roofs by hand and log moisture at every stage.

New Alresford was rebuilt along Broad Street after fire destroyed much of it in the late 17th century, and the Georgian townscape that followed is among the best preserved in Hampshire. The watercress beds and the preserved railway that carries their name are part of the same story, and much of the town centre is listed or sits within the conservation area. Water is the practical issue as well as the historical one. The chalk streams that made watercress growing possible keep the ambient humidity here higher than the surrounding downland, and roof spaces run damp as a result. Foam sealing such a roof traps that moisture against timber that is frequently original. The rot we find in Alresford is often advanced, and on a listed building the affected rafter cannot be cut out and replaced with treated softwood. Removal is hand-led throughout on this stock, and moisture readings are logged across the job rather than taken once at the end.
A Georgian town this intact depends on its original fabric staying intact, and careless foam removal is one of the faster ways to damage it. We treat the timber under the foam as the thing we are protecting rather than an obstacle between us and finishing, which means hand tools, no chemicals and no heat on historic wood. Given local humidity we also record moisture readings throughout the strip-out, because a surveyor here has more reason than most to ask what condition the structure is in.
