How We Differ from Typical Building-Trade Surveys
In much of the damp-proofing industry, the so-called “survey” is really just the first step of a sales pitch.
Because the main business is selling remedial treatments, thorough testing is often skipped or kept to a minimum.
That approach can easily miss how damp and mould have already affected indoor air quality and occupants’ health— or how problems can resurface elsewhere even after structural repairs.
At London Damp Survey, we take the opposite approach.
We focus entirely on unbiased investigation and reporting the facts, not selling you building work.
Our trained team uses calibrated equipment, works to recognised standards, and looks at both the building fabric and the air you breathe.
You get clear, evidence-based answers — so you can make informed decisions, not be steered into unnecessary or premature remedial work.
Customer-First, Not Contractor-Driven
We understand that damp and mould problems can feel stressful and even intimidating.
That’s why we keep the process simple, transparent, and customer-centred:
-
We explain what we’re doing and why -no jargon, no sales tactics.
-
We focus on your health, safety, and peace of mind, not on selling treatments.
-
We’re among the very few survey companies that also check for airborne health threats such as mould spores and VOCs — often found in 8 out of 10 properties with damp issues but rarely adressed by others.
Plain-English, Evidence-Based Reporting
Our surveys result in clear, practical reports that you can act on immediately.
Every report includes:
-
A plain-English summary of what we found and why it matters.
-
Moisture readings, thermal images, and (if relevant) air-sampling data.
-
Clear explanations of how findings relate to recognised standards such as BS 5250:2021, PAS 2035, HHSRS Damp & Mould Guidance, and WHO IAQ Guidelines.
-
Actionable recommendations — focused on the root cause, not unnecessary work.
Our reports are designed to be both easy for homeowners and tenants to understand and robust enough for landlords, housing officers, or tribunals.
Partner Network – Proofing When You Need It
Most companies that test for damp also want to sell you their own proofing services — creating a conflict of interest.
We’re different: we focus solely on diagnosis and advice, and we don’t profit from referrals.
If you do need remedial work, we can introduce you to the one proofing company in London we’ve personally vetted and trust, but the choice is entirely yours.
This approach means you can trust our surveys to be impartial and in your best interest.
