Free Damp Inspections: Too Good to Be True?

If you've discovered mould, a damp patch, or a musty smell in your London property, your first instinct might be to Google "free damp inspection London" — and you wouldn’t be alone.

Plenty of companies offer free damp checks, often with the promise of diagnosing the issue on the spot.

But here’s the reality: Free inspections are rarely surveys — and they’re almost never independent. They’re usually just a sales visit dressed up as advice.

If you're serious about solving the problem properly, especially in older or tenanted properties, you need a professional damp survey — not a rushed quote for work you may not even need.


What Is a Free Damp Inspection, Really?

A free damp inspection typically involves a sales representative from a damp-proofing company visiting your property. Their main goal? To sell their company’s products or services, often involving costly DPC installations, tanking, or plastering.

Here’s what you often don’t get:

  • No thorough investigation of hidden causes

  • No thermal imaging, moisture mapping, or humidity readings

  • No unbiased diagnosis

  • No detailed written report

  • No consideration of long-term ventilation, insulation, or structural factors

In many cases, the person attending isn’t even a qualified surveyor — they’re a salesperson with minimal training.


The Risks of Relying on Free Damp Checks

Relying on a free inspection might seem like a safe starting point, but it often leads to:

1. Misdiagnosis

Condensation is frequently mistaken for rising damp — leading to unnecessary DPC installations. We’ve seen this mistake made repeatedly in London flats where poor ventilation is the real issue.

2. Over-treatment

Because the free inspection is tied to selling services, the solution offered is often more than what’s actually needed — costing landlords and homeowners thousands.

3. No Legal or Insurance Value

A free check doesn’t come with a written, signed report you can use for:

  • Tenant disputes

  • Insurance claims

  • Council enforcement

  • Contractor quotes Only a professional damp survey holds this kind of weight.

4. Ongoing Issues

By treating symptoms and not causes, you risk spending money without solving the problem. Moisture can return within months — often in the same spot.


How a Professional Damp Survey Is Different

When you book a professional damp survey in London with us, you get:

Independent Diagnosis

We don’t sell repairs. Our only goal is to identify the real cause — rising damp, penetrating damp, or condensation — and recommend the right fix.

Full Property Assessment

We inspect all affected areas, internal and external, using:

  • Moisture meters

  • Thermal imaging

  • Hygrometers

  • Surface temperature readings

Detailed Written Report

Our reports (delivered after approx. 3 hours of on-site assessment) include:

  • Clear diagnosis

  • Supporting photographs

  • Expert recommendations

  • Evidence for insurance or legal use

These documents are trusted by landlords, letting agents, legal teams, and local councils across London.


Real Example: When Free Advice Cost More

One landlord in Hackney was quoted £4,500 for a new damp-proof course by a company that offered a free inspection. Before going ahead, they booked our paid damp survey for peace of mind.

Our report found no signs of rising damp — the issue was trapped humidity caused by a sealed subfloor and blocked air bricks.

We saved the client thousands — and gave them evidence to back up a proper fix.


Why Pay for a Damp Survey?

Because in London’s complex housing stock — especially with so many Victorian and Edwardian buildings — guesswork can cost you.

A paid damp survey gives you:

  • Confidence in the diagnosis

  • Protection from unnecessary repairs

  • A trusted document for your records

  • Real expert guidance — not a sales pitch

If you’re a landlord, the cost of a damp survey is minor compared to:

  • Rent repayment orders

  • Legal fees

  • Void periods due to unresolved issues

  • Loss of tenant trust
