Emsworth's harbourside cottages face salt air and old timber in the same roof. We work the foam off by hand and log the moisture evidence your surveyor will want.

Emsworth's character comes from the harbour and the mill ponds, and from the cottages built close to the quay when the town lived on oyster fishing and milling. A good share of that housing predates modern building methods by a long way, and the roof timber in it has spent well over a century in salt air. That pairing makes foam here worse than the sum of its parts. Salt air raises the ambient moisture the roof has to cope with, and old timber has none of the treatment or membrane protection a modern roof relies on. Seal that space with foam and the damp stops leaving. What we find underneath tends to be further along than owners expect, and because the structure is old, replacing a failed rafter is not the routine swap it would be on a newer house. Removal on this stock is hand-led throughout, worked along the grain, with nothing chemical or abrasive near timber that cannot be replaced like for like.
Most firms handle either period property or coastal property. Emsworth needs both at once, and the combination is what makes the survey matter. We check the condition of the timber before agreeing a method, because on a harbourside cottage the question is not only how to get the foam off but whether the structure underneath can take the work at all. If a rafter needs treating or splicing we say so at quote stage. Everything is photographed from survey to completion, with moisture readings logged rather than estimated.
