What this service includes
Service Overview
Unseen leaks and drafts can undo even the best renovations. Trevor’s approach is simple and steady: measure first, understand how air and water move through your home, then invest where it counts. With blower-door testing and thermal imaging, we pinpoint leakage paths (downlights, sash frames, service penetrations) and moisture risks so your upgrades deliver comfort, durability and lower running costs — without guesswork.
What You Can Expect
- Blower-door test (50 Pa) — quantify whole-house air leakage and identify problem zones room-by-room.
- Thermal imaging under pressure — reveal cold bridges, missing insulation and moisture-affected areas.
- Smoke & tracer checks — visualise leaks at downlights, vents, skirtings, penetrations and chimney/flue paths.
- Moisture & roof interface inspection — link stains and damp patches to drainage, flashings and condensation risk.
- Prioritised action plan — practical sealing, insulation and planned ventilation measures, in the right order.
- Optional re-test — verify improvements after works so you know the results are real.
In short: we find the real pathways causing drafts and damp — then give you a clear, builder-practical plan to fix them and prove the outcome.
Where This Service Fits Best
We’re often called to older or wind-exposed homes in:
Niche cross-overs we handle
- Home performance upgrades — sealing + insulation paired with controlled ventilation to manage condensation and IAQ.

FAQs
-
What is a blower-door test?
A calibrated fan creates a pressure difference (typically 50 Pa) to measure air leakage and make drafts visible. -
Will sealing make the house stuffy?
Not when it’s planned. We pair sealing with purposeful ventilation so you keep fresh air without the drafts. -
Can you test in summer/warm weather?
Yes. Thermal contrast helps, but we adjust methods (pressure, timing, imaging) to suit conditions. -
How should we prepare for testing?
Close windows/doors, set HVAC to off, cover open fires and let us access roof space and wet areas. We’ll give you a short prep list. -
Is the pressure safe for the house?
Yes — 50 Pa is a mild pressure. We isolate sensitive appliances and check clearances before testing. -
Will you find roof leaks too?
We often identify entry points and risk details; if needed we’ll scope roofing/overflow fixes with our exteriors team. -
What happens after the test?
You’ll get a prioritised action plan and, if you like, a quote for sealing/insulation/ventilation works. We can re-test to confirm. -
How disruptive is it?
Most homes take 2–4 hours for a thorough assessment; doors stay shut briefly during testing. Minimal disruption.
