Behind every front door

is a life, a family, a story.

Doing right by a building means doing right by the people who love it and depend on it.

A Victorian London terrace opened up from the cellar to the loft, every room warmly lit

The loft

Warm air, cold timbers.

Warm, moist air rising into a cold roof space turns to condensation on the rafters and the underside of the roof. Left alone, it feeds mould and rot.

Loft condensationVentilation

The bedroom

Cold corners, streaming windows.

Condensation gathers where walls are coldest: behind wardrobes and in the corners of outside walls. It is a common cause of black mould, and it can be put right.

Condensation controlMould survey

The walls

Solid brick, open to the weather.

Weathered pointing, cracked render or a leaking downpipe can soak a solid wall from the outside. We find exactly where the water gets in.

Penetrating dampRepointingRender repairs

The living room

A tide mark isn’t always rising damp.

Damp along the skirting can be rising damp, but often it is something else: a raised path outside, a leak or condensation. We find out which before anyone mentions a treatment.

Rising dampDamp proof injectionReplastering

The floors

What lies beneath the boards.

Suspended timber floors need air moving beneath them. When air bricks are blocked or the void stays damp, joists can rot and woodworm can settle in.

Wet rotDry rotWoodwormTimber repairs

The kitchen

Made new, with the same care.

From a new kitchen to a whole-house refurbishment, planned and finished with the diligence we bring to everything else.

KitchensBathroomsRefurbishment

The extension

Where new meets old.

Joining a modern extension to an old house can trap moisture in the original wall and leave the junction prone to movement. Built and repaired properly, the two live happily together.

Every home, the same care

From a Georgian townhouse to a council flat, every front door gets the same diligence.

The same instruments, the same questions and the same written findings within 48 hours.

With our compliments

The survey is our compliment. The decision that follows is yours.

RICS Home Surveys (Level 1, 2 and 3) and electronic leak detection carry a fee.

The honest answer

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

Often, yes.

Many free surveys are there to sell the cure. Ours is built the other way round.

  1. 1We diagnose the cause, not the symptom.Often it’s a blocked air brick, a leaking gutter or a fan too weak for the room.
  2. 2You get the evidence, in writing.Yours to take for a second opinion.
  3. 3The price comes last.Never in the same breath as the diagnosis.
“Internal damp proofing is not currently needed.”
From one of our reports, on a Victorian ground-floor flat where the cause was poor ventilation beneath the floor.

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.

Clarity, on paper

What we found, why it matters and what, if anything, should happen next.

  1. EvidencePhotographs, measurements and instrument readings.
  2. JudgementProfessional interpretation of what we observed.
  3. CostsItemised, last, and only where work is justified.

In writing within 48 hours. Yours to keep, whatever you decide.

Our promise

A 10-year insurance-backed guarantee, IBG Term 10, transferable with the property.

Included as standard, covering the treated works set out in your written guarantee. Insurance-backed, so it stands even if we cease to trade, and it passes to the new owner if you sell.

Questions

Asked, and answered plainly.

Is the survey really free?

Yes. Every survey we offer is free, apart from RICS Home Surveys and electronic leak detection (ELD), which carry a fee. There is no obligation to instruct us afterwards.

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 happens on the visit?

A specialist looks at the building inside and out, takes moisture readings, uses a thermal camera where it helps and flies a drone over the roof if it is needed. We explain what we see as we go.

The inspection is non-intrusive. Nothing is opened up without your permission.

When will I have the findings?

Within 48 hours, in writing: readings, photographs and findings. The report is yours to keep, and to take elsewhere for a second opinion.

Will you tell me if I don’t need damp proofing?

Yes. If you don’t need damp proofing, we’ll tell you. Often the cause is simpler: a blocked air brick, a leaking gutter, ground raised against the wall, or condensation from everyday life.

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.

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.

What does the guarantee cover?

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.

Who carries out the surveys?

Surveys carried out by CSRT/CSSW-qualified surveyors, and PCA-qualified surveyors. RICS Home Surveys are carried out by Chartered Surveyors. Prime Building Care is TrustMark registered.

Do you carry out RICS Home Surveys?

Yes, at Level 1, 2 and 3, carried out by Chartered Surveyors. These carry a fee.

Level 1 suits newer homes in good condition. Level 2 suits most conventional homes in reasonable condition. Level 3 is for older, larger, altered or listed homes, or where you plan works.

Do you do the work as well?

Yes, when you would like us to: damp proofing, basement tanking and waterproofing, timber treatment, mould removal and ventilation, replastering, roofs, structural repairs, kitchens, bathrooms, extensions and refurbishment. The report is yours whichever way you go.

What is Awaab’s Law?

Awaab’s Law sets legal timescales for social landlords in England to deal with hazards such as damp and mould. Since October 2025, a significant hazard must be investigated within 10 working days of the landlord becoming aware of it. Tenants must have a written summary within 3 working days of the investigation concluding, and relevant safety work must follow within 5 working days. Emergency hazards must be dealt with within 24 hours.

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.
