The short answer
It depends on the loft, and no honest figure can be given without seeing it. Removal is priced on the amount of foam, its type, how thickly it was sprayed and how easily the work area can be reached. A loft in Andover or one of the villages around it is judged the same way: a survey first, then a single written total.
What decides the price
Four things carry the weight. The first is the area to be cleared: a small loft over a single bedroom is a different job from the full roof void of a detached house. The second is the thickness of the foam, because a thin coat can be scraped away while a deep fill has to be cut, lifted and carried out in many loads.
The third is the type of foam. Open-cell foam is softer and more flexible, and closed-cell foam is denser and more rigid, so they behave differently under the tools. Our guide to open-cell and closed-cell spray foam explains the difference.
The fourth is what lies under the foam. Sound timbers and felt mean a clean job. Damaged felt, wet timber or hidden fixings add work that nobody can see until the foam is lifted, and part of the point of a survey is to look for the clues beforehand.
None of it can be added up from a postcode. Planning them together avoids paying for the same access twice, and keeps each step in the right order.
Access and the working conditions
How the crew reaches the foam is the factor people forget. A wide hatch with a boarded floor and good headroom is quick to work in. A small hatch, a loft with no boarding and a low pitched roof with sloping ceilings means everything is done on hands and knees, carried in small amounts, and moved a long way to the door.
Where the foam is also matters. Foam on a flat section under the main slope is easier to reach than foam packed into the eaves, behind cross-braces or around a chimney stack.
Outside the house, access to the property counts too. Waste has to be carried out and loaded, so the distance from the door to the vehicle and the width of the drive come into the job. Some roofs may call for scaffold, for example if the work includes a section of re-roofing, so ask whether it sits inside the figure. That is a question to ask every firm you invite, along with whether the total price includes VAT. For a loft in the Andover area, we judge all of this at the survey visit, not from a map.
One total price, after the survey
We do not quote for foam removal from photographs or a phone call. A survey comes first: we look at the foam and the roof structure we can reach, photograph what we see and explain it in plain words. The price follows in writing as one total, so you know where you stand before any work is booked.
It is worth getting more than one. Citizens Advice recommends collecting at least 3 written quotes. Check that each covers the same job: which areas of the loft, whether the foam is removed in full or in part, whether the roof timbers are checked and photographed once exposed, and who takes the waste away. Two figures for different jobs cannot be compared.
Be wary of anyone who names a price at the door, offers a discount for deciding on the spot or says the work must be done now. A reasonable firm lets you think. Our guide to spray foam doorstep sales sets out your rights, including the 14-day cancellation period that can apply to a contract signed at home.
Costs that come before and after removal
Removal is rarely the only cost, and knowing the others avoids a surprise. A survey before the work is the first. If the roof is going to be looked at as well, the price of that is a separate thing; the spray foam survey cost answer sets out how it is priced.
With the foam gone, the loft will need insulating afresh. That can be mineral wool laid between and over the joists, or another product chosen for the roof type. If the felt or timbers need attention, repair or replacement belongs in the plan before new insulation goes in. The pages on insulation after spray foam removal and re-roofing after spray foam removal cover the choices.
VAT is the last item to check. Removal attracts the standard rate, and the total you are given should say if it includes VAT. Our spray foam removal page describes the whole sequence, and you can decide how much of it you need once the survey has shown what the loft contains. Each of those is worth asking about at the survey, so that nothing appears on the final total that you have not seen coming.
