Thermal insulation survey in Exeter
Professional thermal insulation survey services in Exeter and surrounding areas. Local, reliable handyman - no job too small.
Location
Exeter, Devon
Whole-property thermal imaging survey using our DJI Matrice 4 Thermal drone. Maps heat loss through walls, roof, windows, and doors - showing you exactly where your energy bills are going and where insulation is failing.
Stop Heating the Street
You're paying to heat your home. But how much of that warmth is escaping straight through the walls, roof, and windows? In older Devon properties, the answer is often shocking.
A thermal insulation survey shows you exactly where the problems are - so you can fix the right things first.
💡 Pro tip: Even homes with "new" insulation can have gaps. Cavity wall insulation settles over time, and loft insulation gets compressed or disturbed. A thermal check reveals what's actually working.
Common Issues We Find
| Problem | Where | Impact |
|---|---|---|
| Settled cavity insulation | External walls | Major heat loss through bare sections |
| Loft insulation gaps | Around hatches, pipes, edges | Heat pours through unprotected areas |
| Failed window seals | Double/triple glazing | Cold air leaking in around frames |
| Thermal bridging | Lintels, wall ties, junctions | Cold spots where metal conducts heat |
| Draughty doors | Front, back, patio doors | Air leakage you can feel but can't see |

Why Choose Us for Thermal insulation survey in Exeter?
Maps heat loss across your entire property
Identifies failed or missing wall insulation
Spots draughts around windows and doors
Helps prioritise insulation spending
What to Expect
Step 1: Discussion
I find out about your property - age, construction type, known issues, recent work. This helps focus the survey on likely problem areas.
Step 2: Survey
Aerial thermal imaging covers the roof and upper structure. Ground-level thermal checks cover walls, windows, doors, and ground floor. Every external surface is captured.
Step 3: Report
You get a complete thermal map of your property with clear annotations showing where heat is escaping and what to prioritise fixing first.
🔧 DIY Tips
Some heat loss signs you can spot yourself:
🔧 Quick checks
- Hold your hand near window frames on a cold day - feel draughts?
- Check loft insulation depth (should be 270mm minimum)
- Look for condensation patterns on windows (worse = more heat loss)
- Feel external walls from inside - cold patches indicate poor insulation
📐 Room-by-room approach
- Note which rooms are hardest to heat
- Check radiators aren't blocked by furniture
- Feel around skirting boards for draughts
- Check loft hatch seals properly
⚠️ What you can't check
- Cavity wall insulation condition (without drilling)
- Insulation behind plasterboard
- Heat loss through the roof structure
- Thermal bridging at hidden junctions
💡 Pro trick: Light an incense stick and hold it near windows, doors, and electrical sockets on a windy day. The smoke shows you exactly where air is getting in. Cheap and surprisingly effective.
Rather leave it to a pro? No problem - that's what I'm here for. Give me a call.
Good to Know
🏠 Planning insulation work? Get a thermal survey first. It shows you exactly which areas need attention, so you invest in the right improvements rather than blanket-treating everything.
Exeter's housing stock is particularly varied - from Georgian city centre terraces with solid stone walls to 1960s estates with cavity walls. Each needs a different approach, and thermal imaging reveals what's actually going on behind the plaster.
Best done October to March when the temperature difference between inside and outside is greatest. But worth doing any time if you have specific concerns.
Frequently Asked Questions
What's the difference between this and a thermal roof survey?
A roof survey focuses on the roof structure from above. An insulation survey covers the whole property - walls, windows, doors, roof, and ground floor. It's a complete thermal health check of your home, identifying everywhere heat is escaping.
Will it show if my cavity wall insulation has failed?
Yes - this is one of the most common things we find. Failed or settled cavity wall insulation shows up clearly as cold patches on the thermal image. You can see exactly which sections have failed rather than guessing.
My house has solid walls - is a thermal survey still useful?
Absolutely. Solid walls are the biggest heat loss culprit in older properties. A thermal survey shows you exactly how much heat you're losing and helps you decide whether internal or external insulation is worth the investment for your specific property.
Can I use the results for a grant application?
The thermal survey provides evidence of insulation performance that can support grant applications and energy improvement plans. Some local authority grants and ECO schemes accept thermal survey evidence as part of the assessment process.
How accurate is the temperature reading?
The DJI Matrice 4 Thermal uses a radiometric camera that records precise temperature data at every pixel - not just approximate colour ranges. It's accurate to within ±2°C, which is more than sufficient to identify problem areas.
