An insulation assessment in Barnstaple, Devon is a non-invasive survey that maps every insulated surface in your property and grades its real-world performance. We check loft rolls, cavity wall fill, open cell spray foam and closed cell spray foam, then test for moisture with a calibrated moisture meter. You get a room-by-room report showing where heat is escaping, where condensation is forming and what it will cost to put right.
Barnstaple's Atlantic weather drives damp into north-facing walls and roof timbers, and a lot of older stock around Pilton and Newport still carries spray foam installed decades ago. If you are selling and a lender has flagged the insulation, or you simply want to know why the back bedroom is always cold, an insulation survey near me Barnstaple searches often start with exactly that problem. We answer it with readings, not guesswork.
Every assessment is a fixed-fee survey with a written report. Here is exactly what is covered, and what we quote separately if you decide to act on the findings.
We inspect the loft space, roof timbers, felt and any visible insulation. Moisture meter readings are taken at multiple points to detect trapped damp. We photograph anything that looks like rot, condensation or failed foam.
A thermal imaging camera scans internal walls and ceilings to reveal cold spots, missing insulation and air leaks. We run the heating first so the temperature difference is clear. Every anomaly is photographed and tagged to its room.
Where accessible, we inspect cavity wall insulation through existing vents or by borescope. We check for foam bridging the cavity, which causes damp. If the cavity is not accessible, we note that in the report and recommend next steps.
If spray foam is present, we take a small core sample to confirm whether it is open cell or closed cell and check its condition. Samples are tested for isocyanate residue where relevant. Results come back within 48 hours.
You receive a PDF report with photographs, thermal images, moisture readings and a clear recommendation for each area: leave, top up, or remove. Indicative costs are included so you can budget. Reports are issued within 24 hours.
A technician calls you after you have read the report to talk through the findings and answer questions. There is no charge for this call and no obligation to book any work. We want you to understand exactly what is going on in your property.

A technician arrives with a thermal imaging camera, moisture meter and PPE. We inspect the loft, roof timbers, cavity walls and any visible spray foam, recording surface temperatures and moisture percentages room by room. A typical three-bedroom house takes 90 minutes.
We run the thermal camera across internal walls and ceilings after the heating has been on for at least an hour. Cold bands show where insulation is missing or has slumped. We photograph every anomaly and tag it to the room it belongs to.
Where spray foam is present, we take a small core sample to identify whether it is open cell or closed cell and check for isocyanate residue. Foam that has pulled away from timber or gone brittle gets flagged for removal. Lab turnaround is 48 hours.
You receive a PDF report with photographs, moisture readings, thermal images and a clear recommendation for each area: leave, top up, or remove. We include indicative costs so you can budget. Reports are usually issued within 24 hours of the site visit.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Reveals temperature differences across walls and ceilings, showing exactly where insulation is missing, compressed or wet. We use it after running the heating so the contrast is clear.
Measures moisture content in timber, plasterboard and insulation. Readings tell us whether damp is active or historic, and whether roof timbers are at risk of rot.
Cuts through cured spray foam cleanly so it can be pulled away from timber and masonry. We use it during removal work that follows an assessment.
For precision cutting in tight loft spaces and around roof timbers. It lets us remove foam without damaging the structure underneath.
Captures dust and foam particles during removal. Paired with a negative air machine, it keeps your living space clean while we work.
Removes foam from delicate surfaces without water or chemicals. We deploy it when the assessment shows foam bonded to fragile substrates.
Used on stubborn foam that will not shift mechanically. We only use it where the assessment confirms the substrate can take it.
A three-bedroom semi in Pilton had spray foam in the loft. The buyer's lender refused to lend until the foam was assessed and documented. The seller had no report and the sale was on the brink of collapsing.
We surveyed the property within five days, took core samples and issued a lender-format report. The foam was closed cell and in poor condition, so we quoted removal. The lender accepted the report, removal was completed, and the sale went through six weeks later.
A homeowner in Roundswell had a back bedroom that never warmed up, even with the heating on full. Bills were climbing and the room was unusable in winter. They suspected the insulation was missing but could not see where.
Thermal imaging showed a two-metre section of external wall with no insulation at all, plus a smaller gap around the window reveal. We recommended a targeted top-up rather than full removal. After the work, the room reached temperature in half the time.
A landlord in Barnstaple Town Centre had a tenant complaining of a musty smell in the upstairs hallway. The loft had spray foam installed years earlier and no ventilation. Moisture readings showed timber at 28 percent, well into the rot risk zone.
We removed the foam, dried the loft with air scrubbers and treated the timbers. Follow-up readings dropped to 14 percent within three weeks. The musty smell disappeared and the tenant renewed their lease.
