Close out complaints with evidence, not guesswork.
Recurring damp, mould and condensation complaints across a managed portfolio cost time, money and goodwill. We diagnose the real cause once, properly — so the remedy works the first time and the file is defensible.
Block and property managers sit between leaseholders, freeholders, tenants and contractors — and a mould complaint can ping between all of them for months. The usual cycle of 'wipe it, repaint it, fit a fan' fails because nobody has diagnosed whether the driver is a building defect, inadequate ventilation, a thermal bridge or occupant moisture load. We provide an independent, measured investigation that pins down the mechanism and gives you a clear, costed, defensible course of action.
The challenges we solve
- Repeat mould complaints in the same flats despite repeated redecoration.
- Disputes over liability — building defect versus occupant lifestyle versus inadequate ventilation.
- Communal and cold-corner condensation in 1960s–80s concrete-framed blocks with thermal bridging.
- Extract fans and trickle vents that were never commissioned or are now ineffective.
- Rising regulatory and reputational pressure to act on damp and mould promptly and on evidence.
How RetrofitIQ supports you
Independent mould & damp investigation
Measured diagnosis — surface temperature versus dew point, humidity logging, thermal imaging — to establish the true mechanism and apportion cause fairly.
Ventilation assessment
Airflow measurement on extract and supply systems to confirm whether ventilation meets the moisture load, and what upgrade is needed.
Portfolio triage
Consistent, comparable reporting across multiple units so you can prioritise spend where the risk is greatest.
Defensible documentation
Clear written evidence and recommendations to support your response to residents and freeholders.
- Per-unit diagnostic report with cause, evidence and recommended remedy
- Measured ventilation rates against requirement
- A fair, evidence-based view on liability where relevant
- Prioritised remedial plan with indicative costs
- Optional remediation by the same accountable team
Common questions
Can you assess multiple flats in one visit?
Yes. For blocks we plan portfolio visits to survey several units efficiently and report in a consistent, comparable format so you can prioritise.
Do you help apportion responsibility fairly?
Our role is to measure and diagnose. Where the evidence shows a building defect, inadequate ventilation or occupant moisture load — or a combination — we say so clearly, which helps resolve disputes.
Is your report suitable for our compliance file?
Yes. Reports are written to stand up to scrutiny from residents, freeholders and, if needed, legal review.
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.
