Independent diagnostics for damp, mould and stock-wide retrofit decisions.
Social landlords face the sharpest scrutiny on damp and mould and the biggest retrofit programmes. We provide the independent, measured evidence to respond properly to complaints and to de-risk fabric upgrades at scale.
Awaab's Law and the Social Housing Regulation regime have made measured, timely diagnosis of damp and mould a statutory expectation, not a nicety. At the same time, decarbonisation programmes are pushing large-scale insulation and ventilation works into occupied homes — exactly the conditions where badly specified retrofit creates interstitial condensation and mould. We support both: independent investigation of resident complaints, and a building-physics check on retrofit specifications before they reach the stock.
The challenges we solve
- Statutory timescales for investigating and acting on damp and mould complaints.
- Distinguishing building defects, ventilation failure and occupant moisture load fairly and on evidence.
- Large 1960s–80s concrete and system-built blocks with chronic thermal bridging and cold-corner mould.
- Avoiding the wave of failed IWI installations PAS 2035 was written to prevent.
- Ensuring ventilation is upgraded whenever the envelope is tightened.
How RetrofitIQ supports you
Independent damp & mould investigation
Measured, Awaab's-Law-ready diagnosis with clear cause, evidence and proportionate remedy for each affected home.
Pre-retrofit fabric assessment
Baseline thermal imaging, airtightness and moisture-risk review aligned to PAS 2035 before insulation is specified.
Independent retrofit review
A manufacturer-neutral check on proposed IWI/EWI and ventilation build-ups to design out moisture failure.
Verification at completion
Post-works re-testing and thermal imaging to evidence that the upgrade performs as designed.
- Consistent per-home diagnostic reporting across the stock
- Cause, evidence and proportionate remedy for each complaint
- PAS 2035-aligned moisture-risk review of retrofit measures
- Measured verification of completed works
- Defensible documentation for the regulator and residents
Common questions
Can you support an Awaab's-Law response?
Yes. We provide prompt, measured diagnosis with a clear written record of cause and remedy, designed to support statutory timescales and resident communication.
Do you review our retrofit contractor's specification?
We provide an independent, manufacturer-neutral building-physics review of proposed insulation and ventilation build-ups to design out interstitial condensation before works begin.
Can you work at portfolio scale?
Yes. We plan surveys and report in a consistent, comparable format so you can triage and prioritise across the stock.
Investigate → Diagnose → Design → Remediate → Verify
RetrofitIQ is not only a diagnostics company. We take projects from first investigation through to verified improvement — and you decide how far we go. Engage us for an investigation on its own, an investigation plus targeted remedial works, or a complete building-performance and retrofit project.
A measured diagnosis — thermal imaging, blower door testing, moisture and building-physics analysis — with a clear, costed report you can act on however you choose.
We investigate, then carry out targeted remedial works — airtightness, insulation, ventilation or thermal-bridge corrections — and verify the result.
A full fabric-first, Passive House-informed retrofit from diagnosis through design, installation and verification — one accountable team, one point of responsibility.
