Most spray foam removal jobs in a Yeovil house take between one and three working days, with the average three-bed semi finishing in two. A straightforward loft extraction on a modern property can be done in a single day, while a full roof or cavity wall removal on an older Somerset stone cottage often runs to three or four days. What follows is a plain breakdown of the timescales we see week in, week out across Yeovil, plus the specific things that push a job from one day into three.
How long does spray foam removal take in a Yeovil house?
Spray foam removal is the controlled extraction of cured polyurethane foam from a loft, roof, cavity or floor void, carried out when the foam is trapping moisture, failing a mortgage survey, or blocking ventilation. In Yeovil, the duration depends almost entirely on where the foam sits and how much of it there is.
As a working guide for 2026, here is what we quote before we have even seen the property:
- Loft only, open cell, 3-bed semi: 1 day (roughly 6-8 hours on site)
- Loft only, closed cell, 3-bed semi: 1-2 days
- Loft plus rafters, 4-bed detached: 2-3 days
- Full roof deck removal: 2-4 days
- Cavity wall extraction: 1-2 days depending on wall length
- Bungalow loft, single-storey: 1 day in most cases
Those figures assume reasonable access and no hidden surprises. The moment we find saturated timbers, a blocked eaves gap, or foam that has bonded to felt and tile battens, the clock moves.
What actually sets the timescale on a Yeovil job
Four things drive the duration of spray foam extraction in Yeovil Somerset more than anything else: foam type, coverage area, access, and what we find underneath.
Foam type - open cell versus closed cell
Open cell foam is soft, spongy and comes away in large chunks. A two-person crew clears a typical 50 square metre Yeovil loft in a day. Closed cell foam is dense, rigid and bonded hard to the substrate - it has to be cut back in sections, which roughly doubles the labour time on the same area.
Coverage area
We measure in square metres, not rooms. A 3-bed semi in Yeovil usually has 45-60 square metres of loft floor. A 4-bed detached on the edge of town can hit 90 square metres or more. Double the area, double the time.
Access
A standard loft hatch with a clear run to the eaves is quick. A hatch behind a fitted wardrobe, a loft with no boarding, or a roof void only reachable from outside adds half a day before extraction even starts.
What is underneath
This is the one nobody can predict from a photo. If the foam has been holding moisture against timbers for years, we may need to treat or replace sections of wood before we can sign the job off. That is where a one-day job becomes three.
If you want a proper number rather than a range, an insulation assessment in Yeovil, Somerset gives you an accurate scope before any work is booked.
Typical durations by property type in Yeovil
Yeovil's housing stock splits neatly into three groups, and each one behaves differently when we remove foam.
Post-war semis and terraces
The bulk of Yeovil's housing - the streets around Pen Mill spray foam removal and similar residential areas - is 1930s to 1970s brick. Lofts are simple pitched roofs with felt under tile. Most of these come in at one to two days for a full loft extraction.
Modern estates
Newer builds on the edge of town, including the Houndstone spray foam removal area, tend to have trussed roofs with limited loft space. That actually speeds things up - less area, better access - but the foam is often closed cell, which slows it back down.
Older stone and cob properties
Yeovil's older properties, particularly around the town centre and towards the villages, have thicker walls, irregular roof lines and no modern felt. Foam here has usually been sprayed directly onto the underside of tiles, and it takes longer to remove without damaging the roof.
Does spray foam removal take longer in older Yeovil properties?
Yes - older Yeovil properties typically add one to two days to a spray foam removal compared with a modern build of the same size. There are three reasons.
First, older roofs were not designed for spray foam. There is no breathable membrane, so the foam has often been sprayed directly onto tile undersides or onto old bitumen felt. Removing it without cracking tiles takes patience and hand tools rather than just a scraper.
Second, the timbers are often already damp. We have pulled foam off 100-year-old rafters in Yeovil and found soft wood underneath. That means cutting out and splicing in new timber, which is carpentry time on top of extraction time.
Third, access is harder. Older properties frequently have small hatches, low headroom and awkward roof geometry. A job that would take six hours in a 1990s semi can take ten in a Victorian terrace two streets away.
If your property is in one of the older parts of town, expect the upper end of every range we quote.
Can spray foam removal be done in one day in Yeovil Somerset?
Yes, in specific circumstances. A single-day spray foam removal in Yeovil is realistic when all of the following are true:
- The foam is open cell
- It is confined to the loft floor between joists
- The total area is under 60 square metres
- Access is straightforward
- There is no timber damage underneath
That covers a good number of the standard three-bed semis we work on. It does not cover closed cell foam, roof deck removal, or anything where the foam has been in place for 15 years or more.
Where a one-day turnaround is genuinely needed - a mortgage deadline, a surveyor revisit, a sale completing - we can sometimes put a larger crew on the job and compress the schedule. Our same day spray foam removal in Yeovil, Somerset service exists for exactly those situations.
What affects how long spray foam removal takes in Yeovil
Beyond the headline factors, several smaller details move the needle on a Yeovil job.
Method used
Hand tools are slow but precise. Mechanical cutting is faster but riskier on delicate substrates. For foam bonded to fragile surfaces, we use dry ice blasting spray foam removal in Yeovil, Somerset, which freezes the foam so it cracks off cleanly without gouging the timber or felt underneath. It is not always the fastest option, but it is often the one that avoids a re-roof.
Waste removal
Extracted foam has to be bagged and taken away. A full loft produces 15-25 builder's bags of waste. Loading and disposal adds two to three hours to the job, and it is included in the timescale we quote.
Weather
Roof work in Somerset in winter is weather-dependent. We do not remove roof foam in heavy rain, and we do not send crews onto wet roofs. A January job can lose a day to weather that a June job would not.
Making good afterwards
Once the foam is out, the loft usually needs ventilation restored, insulation replaced and any damaged plasterboard patched. We build that into the schedule rather than treating it as an afterthought.
Common mistakes that stretch the job out
The jobs that overrun are almost always the ones where something was missed at the survey stage. Here is what we see.
- Quoting from photos alone. A photo cannot show you damp timbers or foam that has crept behind a party wall. Every job we price gets a physical survey first.
- Assuming all foam is the same. Open cell and closed cell behave completely differently. Quoting a closed cell job on open cell timescales is how a one-day job becomes three.
- Ignoring the cavity. Foam in the loft often means foam in the cavity wall too. If that is not picked up at survey, you get a second visit and a second disruption.
- Not planning for waste. Twenty bags of foam do not fit in a wheelie bin. Disposal has to be arranged, and it has to happen on the day.
- Booking the wrong season. Roof work in a Somerset winter is a gamble. If the job can wait until spring, it usually goes faster.
We also see homeowners try to remove foam themselves with a scraper and a respirator. It works on small patches of open cell foam. It does not work on closed cell, and it is genuinely risky on old roofs where the foam is the only thing holding a tile in place.
When to call a professional
Call a professional the moment the foam is closed cell, the property is older than about 1960, or a mortgage lender has flagged it on a survey. Those three situations account for nearly every job where a DIY attempt goes wrong.
At Spray Foam Renewal Works, we survey first, quote a fixed price, and tell you honestly whether it is a one-day or a three-day job before you commit. We work across Yeovil and the surrounding Somerset villages, and we handle the waste, the making good and the ventilation reinstatement as part of the same visit.
Frequently Asked Questions
How long does spray foam removal take in a Yeovil house?
One to three working days for most Yeovil houses. A standard three-bed semi with open cell loft foam is typically a single day; closed cell foam, roof deck removal or older stone properties usually run to two or three days.
Does spray foam removal take longer in older Yeovil properties?
Yes, usually by one to two days. Older Yeovil roofs often have foam bonded directly to tiles or old felt, plus damp timbers that need replacing. Access is also tighter, which slows every stage of the extraction.
Can spray foam removal be done in one day in Yeovil Somerset?
Yes, if the foam is open cell, confined to the loft floor, under 60 square metres and there is no timber damage. Closed cell foam, roof deck removal and cavity wall extraction all take longer than a single day.
What affects how long spray foam removal takes in Yeovil?
Foam type, coverage area, access to the loft or roof void, and what is found underneath the foam. Weather also matters for roof work, and waste disposal adds two to three hours to any full loft job.
How many days for spray foam extraction in Yeovil on a 3-bed house?
Typically one to two days for a three-bed Yeovil house. Open cell loft foam is a one-day job; closed cell foam or foam that has spread into the rafters usually takes two days.
