Home Health Diagnostic Survey in East London
A comprehensive whole-home diagnostic assessment combining visual inspection, thermal imaging, moisture, humidity and airflow measurements to identify the root cause of building problems. Specialist building-performance diagnostics across East London — E1-E20 · IG (Ilford, Woodford, Loughton) · RM (Romford, Hornchurch, Dagenham).
Home Health Diagnostic Survey in East London
What we typically diagnose across East London.
From the converted Victorian terraces of Walthamstow and Leyton through the warehouse conversions of Hackney Wick and Bow to the new-build estates of Stratford and Canary Wharf — East London has one of the most varied building stocks in the capital. Our diagnostics-led approach matches the remedy to the actual construction, not a generic assumption.
- Solid-wall Victorian terraces in Stratford, Bethnal Green, Hackney, Leyton and Walthamstow with no cavity to fill
- Warehouse conversions with single-glazed industrial windows and no perimeter thermal break
- Bow and Hackney warehouse conversions with chronic mould on inside faces of single-skin brick walls
- High-occupancy HMOs across Newham and Waltham Forest with persistent kitchen and bathroom condensation
- Warehouse conversions with original cast-iron column-to-floor junctions left open

What's included
What's included
- On-site visual inspection of the property and reported issues
- Thermal imaging survey of suspect areas (walls, ceilings, junctions, windows)
- Moisture readings on affected substrates
- Indoor relative humidity and surface temperature analysis
- Smoke tracing of suspected air-leakage paths (where required)
- Optional blower door test for whole-house airtightness
- Written diagnostic report with findings, photographs and recommendations
Who it's for
Who it's for
- Homeowners experiencing damp, mould, cold or high bills
- Landlords and housing associations investigating tenant complaints
- Architects and developers commissioning pre-purchase or pre-retrofit surveys
- Property managers needing evidence-based investigation reports
Typical findings
What we commonly discover during home health diagnostic survey investigations
- 01Cold reveals around windows and external door heads
- 02Air leakage through unsealed loft hatches and service penetrations
- 03Localised thermal bridges at wall/ceiling and wall/floor junctions
- 04Hidden moisture trapped within wall or floor build-ups
- 05Inadequate extract ventilation in bathrooms and kitchens
- 06Indoor humidity above 65% RH driving condensation on cold surfaces
- 07Previous retrofit insulation installed with workmanship gaps
Findings reflect patterns observed across completed RetrofitIQ projects — every survey is interpreted in the building’s specific context.

FAQs
Home Health Diagnostic Survey — common questions
What is a Home Health Diagnostic Survey?+
It is our complete building-performance investigation of a property — combining FLIR thermal imaging, blower-door airtightness testing, moisture and humidity logging, ventilation checks and a room-by-room visual inspection. Rather than diagnosing a single symptom in isolation, it builds a measured picture of how the whole home performs and pinpoints the root causes of heat loss, cold, damp, condensation, draughts and poor air quality.How is it different from an EPC or a standard homebuyer survey?+
An EPC is a modelled energy rating based on standard assumptions, and a homebuyer survey checks structural condition. Neither measures how your building actually performs. A Home Health Diagnostic Survey is evidence-based: we measure real surface temperatures, real air-leakage rates and real humidity, then explain the building physics behind each finding and how to fix it.What equipment do you use during the survey?+
A calibrated FLIR thermal imaging camera, a calibrated blower door for airtightness testing (where applicable), pin and pinless moisture meters, temperature and humidity data loggers, and where relevant IAQ instruments (CO₂, PM2.5, VOC). Every finding is recorded as measured data, not opinion.How long does a survey take?+
A focused single-issue diagnostic typically takes around 2 hours on site. A full whole-house Home Health Diagnostic with thermal imaging, airtightness testing and moisture logging usually takes half a day or more depending on the property size, followed by the written report.What do I receive afterwards?+
A clear written report with annotated photographs, calibrated thermal images, measured data (surface temperatures, humidity, air-leakage figures where tested), a diagnosis of the root cause of each issue, and a prioritised, costed schedule of recommended improvements you can budget against and implement in stages.Do you cover London and the surrounding areas?+
Yes. We are based in East London (E15) and carry out Home Health Diagnostic Surveys across Greater London, Essex, Kent, Surrey, Hertfordshire and the wider South East.How much does a Home Health Diagnostic Survey cost?+
It depends on the property size and the scope (single-room diagnostic vs whole-house with a blower-door test). We provide a clear fixed price before any work begins. Send us a short description of the issue and your postcode and we will recommend the most cost-effective survey and quote it.Can you carry out the recommended works afterwards?+
Yes. We follow one process — Investigate → Diagnose → Design → Remediate → Verify — so we can design and carry out the recommended insulation, airtightness, ventilation, damp or soundproofing works ourselves and then verify the outcome with measurement. One company, one point of responsibility.Is the survey useful before buying a property or before a retrofit?+
Very. Before a purchase it reveals hidden performance problems and the likely cost to put them right. Before a retrofit it provides the baseline measurements needed to design the right insulation, airtightness and ventilation strategy — and to verify the improvement afterwards.

We don’t simply identify problems. We investigate, diagnose, design solutions, carry out the work and verify the results. Book a Home Health Diagnostic Survey and we’ll tell you exactly which remedial works (if any) are actually needed.
