Damp proofing

One survey, then the right fix for your walls

Damp proofing is the heart of what we do. Damp shows up in a lot of ways, a tide mark low down on a wall, blown plaster, peeling paint, a musty smell or black mould in a corner, and each of those can point to a different cause. We start every job with a proper survey so the treatment matches the actual problem rather than the symptom on the surface.

Once we know what we are dealing with, the work might be a new chemical damp-proof course injected into the wall, hacking off and replastering affected areas with a salt-resistant render, or treating the outside cause of the moisture. Whatever it involves, you get a clear written quote before we start.

How we do it

The typical process

  1. Step 01

    Survey

    Prepare and treat

    We sheet up, remove affected plaster and install the damp-proof course or membrane.

  4. Step 04

    Replaster and finish

The quote

Damp Proofing costs

Every property is different, so we quote each job on its own after a free survey rather than off a description. These are the things that move the figure, and we set it all out in writing before any work starts. The visit is free.

  • The size and number of walls affected
  • Whether replastering is needed as well as a damp-proof course
  • How easy the area is to access
  • Whether the source of moisture also needs work

Common questions

Damp Proofing questions

How long does damp proofing take?

Most domestic jobs are done in one to a few days, depending on how much wall is affected and whether replastering is involved. We provide you with a timescale with the quote.

Can I decorate straight after?

New render needs time to dry out fully before painting, and we tell you how long to leave it for your specific job. Rushing the paint traps moisture and undoes the work.

Do you guarantee the work?

Yes. We treat the cause, not just the surface, and stand behind the damp proofing we carry out. We explain what is covered when we quote.

Do I need to move out during the work?

Rarely. Most damp proofing is done room by room while you stay in the house. We sheet up, keep the mess contained and tell you if any room is out of use for a day.

Can you treat damp in a rented property?

Yes. We work for landlords and letting agents as well as homeowners, and can provide the written report and invoice you need for your records.
