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.
Our experienced roofing team understands the structure beneath your spray foam insulation, allowing us to remove it safely while protecting roof timbers, tiles and other essential components.
With five years dedicated to spray foam insulation removal, we safely remove both open-cell and closed-cell foam using proven techniques that minimise disruption and help preserve your roof's condition.
We believe in straightforward recommendations, competitive pricing and no hidden costs. Every quotation is clear, with free, no-obligation advice to help you make the right decision for your property.
Salt exposure and centuries-old timber in one property raise questions a modern estate never does. These come up most around the harbour.
We take it. Most household recycling centres will not accept spray foam in bulk, and moving it yourself without a registered waste carrier licence is against the law. It leaves under our own licence and you get the Waste Transfer Note as proof of where it went.
Most UK jobs run two to five working days. Where yours falls depends on the size of the roof, how much foam is there and how easy the space is to access. A small loft with a thin layer of open-cell foam sits at the short end, a detached roof bonded in closed-cell at the long end.
There is no flat rate we could give you before seeing the roof. Price turns on the foam type, how much of the roof it covers, the condition of the timber underneath and how hard the space is to reach. The survey is free, and the written figure it produces does not move once work starts.
We come out and get into the roof space. That tells us the foam type, how far it spreads, the condition of the timber underneath and how equipment will reach it. You then get a written quotation covering the whole job. The survey is free and carries no obligation.
It raises the baseline the roof has to cope with. Salt air and standing water nearby both lift the ambient moisture, and foam stops that moisture leaving rather than stopping it arriving. On old timber with no membrane behind it, that is the worst combination we deal with.
Yes, where the method is right. Hand tools along the grain, no solvent and no heat. Where a rafter has already failed we will tell you at survey whether it needs treating or splicing rather than after the fact.
