Overton's mill-village cottages have been altered for generations, so no two roofs match. We map the whole space at survey before quoting a single figure.

Overton sits on the upper Test and grew around its paper mill, which has made banknote paper here for well over a century. The village housing reflects a long working history rather than a single period of development, and a great many of the older cottages have been extended, subdivided or re-roofed more than once. That is the defining feature of the work here. A roof space in Overton is often several structures joined together, built at different dates to different standards, and foam may cover only one section of it. Quoting from the hatch on a property like that is how a job goes wrong, because the part you can see may be the newest and simplest section while the original roof sits beyond it in the dark. We map the whole space at survey, note where the foam starts and stops, and identify which sections are original before agreeing a price or a method.
On a cottage extended three times since the 1800s, the roof is a set of separate structures pretending to be one. We survey all of it, not the part visible from the hatch, because the older section beyond the crawl is where the foam and the damage tend to sit. That survey is what the quote is built on, and it is why the figure holds once we start. If part of the roof needs a different method to the rest, you will know that before the first day rather than during it.
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.
Cottages altered over generations bring their own questions to a survey. These are the ones that come up most in the village.
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.
Yes, and it is common in Overton. Crawl access limits how much equipment goes in at once and makes extraction more important, since carrying material back out by hand through a low void is slow and messy. We factor that into the days quoted.
Only where the foam is, and that is rarely the whole roof on a property like this. We map which sections carry it and which do not, so you are not paying to clear a roof void that was never sprayed.
