Why Choosing the Right Damp Surveyor Matters

Damp problems in London homes can be complex — especially in older Victorian and Edwardian properties found in areas like Hackney, Lewisham, Camden, and Peckham. But not all damp surveys are created equal.

If you’re booking a damp survey, whether as a landlord, homeowner or buyer, asking the right questions up front is crucial. A rushed, biased, or surface-level inspection can lead to misdiagnosis — and that means wasted money on unnecessary repairs.

This guide will walk you through the key questions you should ask before booking a damp survey in London, and how we proudly answer each one.


1. Are You Independent — or Do You Sell Damp-Proofing Services?

Why it matters: Many “free inspections” are just sales visits from companies looking to push chemical DPCs or expensive waterproofing treatments.

What to look for: A truly independent damp surveyor should not sell or install any repair services. Their role is to diagnose the problem, not profit from fixing it.

Our answer: We are 100% independent. We do not carry out damp-proofing work, and we don’t take commission from any contractor. Our only job is to identify the issue and provide an accurate, unbiased report.


2. Will I Get a Written Damp Survey Report?

Why it matters: Verbal advice or quick assessments aren’t enough — especially if you need the findings for a legal dispute, insurance claim, or contractor quotes.

What to look for: A professional damp survey should include a structured, written report with images, readings, diagnoses, and recommendations.

Our answer: Every paid damp survey includes a detailed written report delivered within days of inspection. This includes annotated photos, moisture data, diagnosis of damp type, and professional guidance — written clearly for both technical and non-technical readers.


3. How Long Will the Damp Survey Take?

Why it matters: Some companies promise “full inspections” in under 30 minutes — which rarely delivers the depth needed for proper diagnosis.

What to look for: A full damp survey of a London property should take around 2–3 hours, depending on size and condition.

Our answer: Our damp surveys typically take 3 hours on site, ensuring we assess every relevant area thoroughly. This includes internal and external checks, lofts and basements where accessible, and hidden risk areas like behind furniture or skirting.


4. What Equipment Will You Use?

Why it matters: A proper inspection requires more than just visual observation. Moisture meters, hygrometers, and thermal imaging cameras can all play a role in identifying causes and severity.

What to look for: Surveyors should use diagnostic tools to support findings with data — not guesswork.

Our answer: We use:

  • Moisture meters

  • Digital hygrometers

  • Thermal imaging (where needed)

  • Surface temperature readings All results are logged and included in your damp survey report.


5. Do You Have Experience with London Properties?

Why it matters: London’s housing stock is unique — especially older terraced homes, converted flats, and council buildings. Without this context, many surveyors misidentify rising damp, bridging, or condensation issues.

What to look for: Local experience is essential. The damp causes in a Hackney Victorian terrace aren’t the same as in a 1990s Islington flat.

Our answer: We specialise in London properties, particularly those in older boroughs like Camden, Lewisham, Southwark, Hackney, and Waltham Forest. Our experience helps us spot recurring patterns — and provide tailored solutions.


6. Can I Use the Report for Legal or Insurance Purposes?

Why it matters: If you're a landlord dealing with a dispute or tenant complaint, or a buyer negotiating a property price, you need a report that holds weight.

What to look for: A surveyor with recognised expertise whose report can be used for evidence or mediation.

Our answer: Our reports are routinely used by landlords, agents, buyers, and solicitors across London. They’re structured, signed, and include the kind of evidence you can forward to local authorities or insurers if needed.


7. What Does the Damp Survey Cost — and Why?

Why it matters: If the price sounds too good to be true, it probably is. Free or extremely cheap “surveys” often lead to overselling, poor diagnosis, or incomplete reports.

What to look for: A fair, transparent price for a professional service — ideally from someone who doesn’t benefit from selling follow-up repairs.

Our answer: We charge for our damp surveys because they take real time, expertise, and effort. Each survey includes:

  • 3+ hours on site

  • Moisture readings and imaging

  • In-depth analysis

  • A fully written damp survey report (usually 10–15 pages)

Clients have told us our reports picked up on issues that £3,000 HomeBuyers Reports missed. You’re not just paying for a visit — you’re paying for accuracy and protection.


Bonus: What Happens After the Damp Survey?

Our follow-up support includes:

  • Explaining any part of the report

  • Clarifying next steps

  • Recommending what kind of contractor you’ll need (if any)

  • Helping landlords respond to tenant complaints

  • Supporting buyers in property negotiations

We don’t disappear once the report is delivered — we support you until the issue is fully understood.
