Wall after damp proof plastering

Not sure which one you've got?

Rising, penetrating and condensation look similar and need completely different fixes. Jack will tell you which it is, free.

Torch-on felt being laid

Strip it back. Do it once.

We take the covering off, replace anything rotten and insulate to current regs before the new system goes down.

A flexible coating bridges hairline cracks and sheds water while letting the wall breathe. Ten to fifteen year finishes.

dry outon its own.

Tide marks, blown plaster, black mould, a flat roof that's given up. Jack and William find what's actually causing it, and put it in writing before you spend a penny.

Two trades, one team

We stop water getting in.
Top down and ground up.

Most firms do one or the other. Water doesn't care about the difference — a leaking flat roof and a failed damp course produce the same wet wall. We survey the whole building, so you don't end up paying twice to fix the same stain.

Ground up

Damp proofing across Kent, London & Essex

Rising damp, penetrating damp, salt-contaminated plaster and wet cellars. We inject a new chemical damp proof course using the SecoMUR system, then re-plaster with a salt-inhibiting render so the stain never comes back through.

Flat & pitched roofing

Flat roofs are most of what we do, and we work with any system — torch-on, GRP or EPDM. We strip back to the deck, replace anything rotten and insulate to current regs before the new covering goes down. Pitched roofs too: tile, slate, repairs and full re-roofs.

Coatings, cork
and tanking

Rear elevation finished in flexible wall coating
Exterior

Exterior wall coatings & cork render

A flexible coating bridges hairline cracks and sheds water while still letting the wall breathe. Cork spray render adds an insulating layer on top — useful on solid-wall properties that can't take cavity insulation.

  • Colour and clear wall coatings
  • Cork spray insulating render
  • Crack repair and render patching
  • Full front and rear elevations

Basement tanked and floor screeded
Below ground

Basement & cellar tanking

Cellars and basements sit below the water table, so they need a waterproofing system rather than a damp treatment. We tank the walls and floor to give you a dry, usable room instead of a space you keep the bikes in.

  • Cementitious tanking systems
  • Cavity drain membrane and sump
  • Floor screeding

How it works

Find the cause.
Not just the stain.

Damp gets misdiagnosed constantly. A new damp course won't help if the real problem is a blocked gutter — and you'll have paid for it anyway.

So we survey first, and we tell you what we find even when the answer costs us the job.

  1. 01

    You get in touch

    Form, phone or a WhatsApp photo. A single clear picture often tells us a lot before we set off.

  2. 02

    Jack surveys

    Free and on site. Meter readings inside, ground levels, gutters and drainage outside.

  3. 03

    Findings in writing

    What's causing it, what needs doing — and what doesn't. Including if the answer is "clear your gutter".

  4. 04

    Fixed price

    One itemised figure. It doesn't move unless the scope changes, and we tell you before it does.

  5. 05

    Work & guarantee

    Our own team, clean site, rubbish taken away. Guarantee paperwork handed over at the end.

Think you've found damp?

Don't strip the wallpaper, don't paint over it, don't panic. Take a clear photo of what you're looking at and send it across. Jack looks at it personally and tells you honestly what it's likely to be and what to do next — free, with nothing to book.

Jack is named again and again in these — which is the point. The person who quotes your job is the person who turns up to do it.

Front and back of the house completely revamped. Quoting was quick and detailed, and we kept working through it until everything was covered. Jack sorted the scaffold, the electrician, the gutters and the fascias.

Professional and knowledgeable from start to finish. They turned up when they said they would, cleared up after themselves and explained everything in plain terms. The house is in noticeably better condition.

Polite team and a fair quote. The surveyor spotted the problem straight away, and they fitted us in quickly because we had a carpet fitter booked. Pleasant experience all round.

Straight answers

Questions we get
every week

Is the survey really free?
Yes. Jack comes out, takes meter readings, checks the outside of the property and tells you what he finds — at no cost and with no obligation to use us. If the fix is something simple you can sort yourself, he'll say so.
How do I know it's rising damp and not something else?
Often it isn't. Rising damp leaves a tide mark up to about a metre with salt staining above it. Condensation shows as black mould in corners and around windows. Penetrating damp appears as a patch that worsens after rain. They need completely different fixes, which is why we survey before quoting.
What guarantee comes with the damp proof course?
Our injected damp proof course uses the SecoMUR chemical system and carries a 30 year guarantee. You'll get the paperwork when we hand the job back — worth keeping with your deeds, as buyers and their solicitors will ask for it.
Can you do the roof and the damp at the same time?
Yes, and often that's the right answer. A leaking flat roof or a blocked gutter can cause damp inside that looks identical to a failed damp course. We look at both, so you're not paying one firm to fix a symptom another firm caused.
Do you do emergency call-outs?
We do respond to urgent leaks and storm damage. Ring 01474 612 066 and we'll tell you honestly when we can get to you rather than promising a time we can't keep.
Do you work with landlords and letting agents?
Regularly. We can survey with a tenant in situ, work to a schedule that suits them, and provide the written report letting agents need for their records.
Are you insured?
Yes — £5m public liability, and our teams are employed by us rather than subcontracted, so the same people who quoted the job are the ones in your house.
