Whole Property Survey with Costings

Same price across East Anglia, North London and the West Midlands. HMOs, commercial premises and unusually large properties are quoted individually. No payment is taken to book, and if what you describe does not need a survey, we will say so on the phone.

See real ones: a problem areas survey report (PDF, 22 pages, 5 MB) and a whole property survey report (PDF, 35 pages, 8 MB). Each is published with the client's permission, with only the client, the address and anything personal removed.

Every survey includes

The right instrument, in experienced hands

Every survey is carried out with a Protimeter MMS3, a professional moisture meter used by surveyors and damp specialists across the UK. It measures four things, not one: moisture in the material, moisture beneath the surface without damaging it, humidity and dew point in the air, and surface temperature. Together they show whether damp is coming through a wall or forming on it, which is the difference between penetrating damp and condensation.

But a meter doesn't diagnose damp. A surveyor does. Rory built houses from the foundations up with a master builder before the Royal Marines, and has renovated and extended period homes ever since. That is what tells him what the readings mean in a real house, and when a reading can mislead. Good instruments and experience together are how we find the cause, not just the symptom.

Whole Property Survey with Costings, £500

Everything in our Whole Property Survey, plus a realistic idea of what it will cost to put right.

We inspect every room we can get into, the loft where access allows and a full outside inspection. We find the cause of the damp, not just the symptom, then give you indicative costs for the work needed to fix it. Your report is ready within 24 hours of the survey, and Rory will call you afterwards to talk it through.

If you own the home

Know what the work should cost before the contractors arrive. You'll have the cause, exactly what needs doing and a realistic price range, so you can compare quotes like for like and spot one that's padded, or a damp course you don't need.

If you're buying

Know what you're taking on before you commit. The cause, how far it goes and a realistic cost to put it right, from someone with no interest in the answer. You can plan your budget, and make your decision, on facts. How it works around a purchase

If you're selling

A buyer's survey has flagged damp and the offer is coming down. An independent report gives both sides the same facts: the cause, what's needed and what it should realistically cost. Sometimes that's far less than the worst case being quoted. Sometimes it isn't. Either way, the conversation about price is based on evidence, not guesswork.

Good to know

The costs are indicative ranges, not a quote. We carry out no remedial work, sell no products, and take no commission or referral fee from anyone who carries out repairs, so the report says the same thing whoever books it. It isn't a Level 2 or Level 3 building survey or a valuation, and it doesn't meet any lender requirement. The report is for the person who books it. You're welcome to share it, but only you can rely on it.

Why an independent damp survey matters

Most "free damp surveys" are carried out by the company that sells the treatment. The survey is the sales visit. It is no surprise when the answer is a damp proof course, an injection or a tanking system, whether or not the wall needs one.

Vigilant Surveys does no remedial work at all. No damp proofing arm, no contractor referrals, and no contractor paying us anything in connection with your survey. The report is the only product, so the diagnosis is never shaped by who fixes the problem. Quite often the real answer is far cheaper than the one you were quoted, and when the property does not need the treatment someone has proposed, that goes in writing.

Second opinion on a quote

You have been quoted for damp proofing and want to know whether the wall is actually damp, and why. An independent survey answers that before you spend thousands.

Buying a property

Your Level 2 or Level 3 survey flagged damp readings or a musty smell. What buyers book is our Whole Property Survey with Costings. It finds the cause and gives you indicative costs for the work, so you know what you are taking on before you commit.

Landlords and agents

A tenant has reported damp or mould. An independent, evidence led report shows what was found, when, and what needs doing, and it stands up if the matter goes further.

Your own home

Mould keeps coming back, plaster is blowing or there is a stain that grows after rain. You want the cause, not a guess, and a plan that fixes it once. Damp and mould inspection

"I called Rory in to survey my semi-detached in Stowmarket after noticing some damp issues. He identified the cause straight away, blown render on the external wall allowing water to penetrate. Really impressed by how thorough he was."

Ben Stone · Homeowner, Stowmarket

"Rory surveyed one of my rental flats in Norwich and identified condensation as the cause of mould in the bathroom. A simple fix, he recommended installing an extractor fan, but good to have it properly assessed and documented."

Kit McNiel · Landlord, Norwich

"I live overseas and rent out my home in Stowmarket, so having a reliable, trustworthy surveyor I can call on is really important to me. Rory found the cause of mould in the bathroom straight away."

Damp survey questions

How much does a damp survey cost?

£350 for the problem areas or £450 for the whole property, the same price across East Anglia, North London and the West Midlands, and the figure quoted is the total payable. Both include thermal imaging, calibrated moisture mapping and the written report. HMOs, commercial premises and unusually large properties are quoted individually. If you want indicative costs for the work as well, that is the Whole Property Survey with Costings at £500, our only survey that includes them.

Is the survey really independent?

Yes. Vigilant Surveys carries out no remedial work, sells no products, and takes no commission or referral fee from anyone who carries out repairs. We are paid for the survey and the report, and nothing else.

What is the difference between rising damp, penetrating damp and condensation?

Rising damp is ground moisture drawn up through a wall, typically affecting the lower metre. Penetrating damp comes in from outside through defects such as failed pointing, blocked gutters or cracked render. Condensation forms when warm moist air meets a cold surface and is the most common cause of mould in homes. They look alike on a wall and need completely different fixes, which is the whole point of diagnosing properly before any work is done.

How long does it take and when do I get the report?

Usually 1 to 2 hours on site depending on the size of the property and how many rooms are affected. The written report is prepared within 24 hours of the survey.

Where do you cover?

Based in Suffolk and covering Norfolk, Essex, Cambridgeshire and North London too, all at the same fixed price. Ipswich, Norwich, Cambridge, Colchester, Chelmsford, Peterborough, King's Lynn and the North London boroughs are all regular ground, and so are the M11 corridor and north east London: Epping, Harlow, Bishop's Stortford, Loughton, Woodford, Chingford and Walthamstow. In the West Midlands we cover about an hour's drive across the region, including Wolverhampton, Walsall and Birmingham, at the same prices. Damp surveys in the West Midlands.
