A thermal camera shows the cold spots and hidden moisture the eye cannot see, so we know exactly where to look closer.

Questions

About damp and mould surveys, answered plainly.

Isn’t a free damp survey just a sales visit?

Often, yes. Ours is built the other way round.

We diagnose the cause, not the symptom. You get the evidence, in writing, yours to take for a second opinion. And the price comes last. Never in the same breath as the diagnosis.

If you don’t need damp proofing, we’ll tell you.

Is the damp and mould survey really free?

Yes. The survey is free and there is no obligation to instruct us afterwards. The only surveys we charge for are RICS Home Surveys and electronic leak detection (ELD).

It is free because it is how we earn the chance to do the work. That is exactly why we put everything in writing and leave the decision with you.

What does the survey include?

A specialist looks at the whole building, inside and out: walls, floors, ventilation, gutters and downpipes, pointing, ground levels and the roof line. We take moisture readings, use a thermal camera where it helps and fly a drone over the roof if it is needed.

You then have our readings, photographs and findings in writing within 48 hours.

How long does the visit take?

It depends on the size of the home and what we find. We give you a time window when we confirm your booking, and we never rush the diagnosis.

Will you drill holes or lift floorboards?

No. The survey is non-intrusive. Where it would help to see inside a wall or beneath a floor, for example with a small inspection camera, we explain why and only go ahead with your permission.

How do I know if it is really rising damp?

True rising damp shows low on ground-floor walls, usually no higher than about a metre, and only where moisture can climb from the ground. Many patches blamed on rising damp turn out to be condensation, a leak or a path raised against the wall.

Historic England, RICS and the Property Care Association set out the same principle in their joint position statement: find the cause of the moisture before any remedial work, rather than treating the symptom.

Can a damp meter on its own prove rising damp?

No. Electrical moisture meters are a useful first screen, but salts in old walls can push their readings up, so they cannot diagnose rising damp on their own. We read them alongside everything else the building tells us.

Is black mould harmful?

Government guidance says damp and mould mainly affect the airways and lungs, and can also affect the eyes and skin. Some people are more at risk, including people with asthma or other lung conditions and people with weakened immune systems.

The answer is to remove the mould and deal with the moisture that feeds it, so it does not come back.

What causes condensation, and how is it fixed?

Everyday life puts moisture into the air: cooking, washing, bathing, drying clothes indoors, even breathing. When that air meets a cold wall or window, it turns back into water, and mould follows.

It is fixed by moving moist air out at the source, with extractor fans or positive input ventilation, and by keeping surfaces warmer. We size the fix to the room, not to a catalogue.

I’m buying a home. Do I need a damp survey?

If your surveyor or lender recommends a specialist damp and timber report, we can provide one free. Book it before you exchange so the findings can still shape your decision. If you need a RICS Home Survey as well, we offer Level 1, 2 and 3, carried out by Chartered Surveyors, for a fee.

I rent my home. Can I book a survey?

In a rented home, putting damp and mould right is usually your landlord’s responsibility. The survey is free for your landlord or letting agent, so send them this page or ask them to call us on 0330 520 2584.

If you live in social housing, Awaab’s Law now sets legal timescales for your landlord to investigate and fix damp and mould.

When do I see a price?

Last. The findings come first, and itemised costs follow only where work is justified. The decision is entirely yours.

Can I take your report elsewhere?

Yes. The report is yours to keep, and to take to anyone else for a second opinion or a comparison.

What guarantee comes with the works?

Our treated works carry a 10-year insurance-backed guarantee, IBG Term 10, transferable with the property. It covers the treated works set out in your written guarantee and is included as standard. Because it is insurance-backed, it stands even if we cease to trade.

Which areas do you cover?

Every London borough, and anywhere within the M25. Further afield, call us on 0330 520 2584 and we’ll tell you honestly whether we can help.
