Damp proofing & damp surveys · London & the Home Counties

Damp, diagnosed
properly.

We find the cause before anyone talks about a cure. Written findings within 48 hours — and if you don't need damp proofing, we'll tell you.

It starts
up here.

Forty feet above the room where you noticed it.

Rain doesn't damage
a sound roof.

It waits for one detail to fail.

This is
the way in.

Cracked flaunching at the base of the stack. Nothing you could see from the ground.

Water only needs
the gap for a moment.

Then it's inside the wall, and out of sight.

Now it's
inside.

Finding its way down.

…and shows up
down here.

Months later. In the room you actually live in.

You've been
treating the wall.

The problem was forty feet up.

The rain will try again.
It won't get in.

Written findings within 48 hours. If you don't need damp proofing, we'll tell you.

Your wall next. Book the survey.

The offer

Book a survey.
Written findings within 48 hours.

A surveyor comes out, inspects the property, takes readings, and establishes what is actually causing the damp. You get that in writing — findings, readings and photographs — within two working days. Only then does anyone discuss a price.

Booked surveys go ahead at the time you choose. If you send an enquiry instead, a member of the team will call you back.

The honest answer

"Isn't a free damp survey just a sales visit?"

Often, yes. It's a fair question and it deserves a straight answer rather than a brochure.

The conflict is real: if the person diagnosing the problem is also the person selling the cure, the diagnosis tends to find work. Consumer advice has warned about this for years, and it is the single most common reason people put off dealing with damp at all.

Here's how we take that conflict off the table.

  • We diagnose the cause, not the symptom. Condensation, penetrating damp, a failed detail, a bridged damp-proof course and genuine rising damp all look similar on a wall and need completely different work. Establishing which one you have is the entire job.
  • You get the evidence, in writing. Readings, photographs and findings, within 48 hours — yours to keep, and yours to take to anyone else for a second opinion.
  • The price comes last. Never in the same breath as the diagnosis.
If you don't need damp proofing, we'll tell you.

That sentence costs us work. We'd rather lose the job than sell you the wrong one.

How we survey

Method is the professionalism.

Every survey follows the same three steps, in the same order, every time.

  1. 01

    Inspect

    The whole picture — inside and out. Ground levels, rainwater goods, pointing, roofline details, ventilation, the construction and age of the building, and the pattern of the damage itself.

  2. 02

    Measure

    Moisture readings taken properly and recorded, so the conclusion rests on data rather than on an opinion formed at the door.

  3. 03

    Written cause report

    What is causing it, how we established that, and what putting it right involves. Within 48 hours. A price follows the report — it never leads it.

The guarantee

Ten years, in writing,
and insured behind that.

Our work is covered by a 10-year written guarantee — insurance-backed, so it protects you even if we're not around to honour it, and it stays with the property if you sell.

Layer one

Our written guarantee

If the damp we treated comes back within ten years, we come back and put it right at no cost to you.

Layer two

The insurance behind it

If we ever ceased trading, the insurer pays another contractor to honour the same guarantee. The promise doesn't depend on us still being here.

And

It belongs to the property

The guarantee is linked to the building, not to you personally, and transfers to a new owner if you sell. Buyers' solicitors ask for it — you'll have it.

Included as standard on every guaranteed job — not an optional extra, and not something you have to ask for. Cover applies to the treated works set out in the written guarantee.

Buying or selling

The survey flagged damp. Now what?

A RICS Level 2 or 3 survey rarely says what the damp is. It records elevated readings and recommends you consult a specialist — which protects the surveyor and leaves you with an open question, usually against a deadline.

Our report closes it: what is causing the damp, what putting it right involves, and what it costs. Within 48 hours, in writing, ready to hand to a solicitor or use in a renegotiation.

Selling rather than buying? The same report answers a buyer's survey with evidence instead of a discount — and if we carry out the work, the guarantee transfers to them.

Landlords & housing providers

Root cause, documented.

"Lifestyle" is no longer an answer to a damp and mould report, and a file note saying the tenant dries washing indoors will not stand up when the property is inspected.

We investigate the actual cause and document it: readings, photographs, findings, and what the building needs. An evidence pack you can put on file, act on, and produce later.

Portfolios and multiple units — tell us the scale when you book and we'll plan the visits around it.

We provide building surveying findings, not legal advice.

Questions

The ones worth asking.

Do I really have rising damp?

Probably not. Condensation is by far the most common cause of damp in British homes, and it is frequently the cheapest to resolve — often ventilation, heating patterns and a couple of targeted changes rather than any damp proofing at all. Penetrating damp from a failed gutter, a cracked render or a roofline detail is the next most common. Genuine rising damp exists, but it is diagnosed far more often than it occurs. That is exactly why the survey comes before the quote.

Why was I quoted four thousand pounds elsewhere?

Usually because the quote was for a chemical damp-proof course and re-plastering — the standard treatment for rising damp — on a wall where rising damp was assumed rather than established. It's the default remedy in this industry, it's expensive, and if the water is actually coming in at the roofline or condensing on a cold wall, it will not work. Get the cause established in writing first. If our findings agree that you need it, you'll have evidence for why.

What does the survey actually involve?

A surveyor inspects the property inside and out — ground levels, rainwater goods, pointing, roofline details, ventilation, construction type and the pattern of the damage. Moisture readings are taken and recorded. Expect access to be needed to the affected rooms and, where relevant, to lofts, cellars and the outside of the building. You receive written findings, readings and photographs within 48 hours.

How quickly can someone come out?

Book directly through the booking page and you'll see live availability — pick a time that suits you and the survey goes ahead then. If you'd rather talk to someone first, call and a member of the team will pick it up.

Do you cover my area?

We cover London, Essex, Kent, Surrey and the Thames Valley — the full list of towns and boroughs is set out above. If you're just outside it, call and ask; the honest answer is quicker than a form.

What else do you do besides damp?

Damp proofing, surveying and diagnostics, condensation and ventilation solutions, remedial plastering, basement waterproofing and structural repairs. Damp is where most people find us, but the underlying discipline is the same: establish the cause, specify the right work, guarantee the result.

What does the guarantee actually cover?

The treated works set out in your written guarantee, for ten years. If that damp returns, we return and put it right at no cost. The guarantee is insurance-backed, so it survives us ceasing to trade, and it transfers with the property if you sell. It's included as standard on every guaranteed job.

causing it.
