Damp Wall Replastering and Damp Proofing in Aldershot

Damp ruins plaster. It leaves tide marks, peeling paint, crumbling walls and a musty smell, and if the plaster is not replaced with the right materials, the problem shows straight through again.

Skim Infusion replasters damp-affected walls, helps tackle condensation and mould, and installs tanking and membrane systems for cellars and basements. We work across Aldershot, Farnborough, Farnham, Fleet, Camberley and the surrounding towns.

Fix the Cause First

Replastering only lasts if the source of the damp has been dealt with. Common causes include leaking gutters and downpipes, high ground levels against the wall, failed render, plumbing leaks, poor ventilation and missing or failed damp-proof courses.

If you are not sure what is causing your damp, we recommend getting the cause properly identified before replastering.

Replastering Damp-Damaged Walls

When damp has affected a wall, the old plaster is often contaminated with salts that keep drawing in moisture. Simply skimming over it does not work. We:

  1. Remove the damaged plaster, usually to around a metre high or beyond the visible damage

  2. Let the wall dry and prepare the surface

  3. Apply a suitable salt-resistant or renovating plaster system

  4. Finish with a smooth skim coat, ready to decorate with a breathable paint

On older solid-walled homes we may recommend lime plaster instead.

Condensation and Mould

Black mould on walls, ceilings and around windows is usually caused by condensation, not rising damp. Warm, moist air from cooking, showers and drying clothes hits cold walls and turns to water.

We can help by:

Tanking and Cellar Waterproofing

Below-ground rooms such as cellars and basements need a different approach, because water pressure from the surrounding ground pushes moisture through the walls. We install:

  • Cavity drain membranes (such as Delta)

    A studded membrane fixed to the wall that lets water drain away behind it, ready for plasterboard or plaster

  • Cementitious tanking

    A waterproof coating applied directly to the wall before plastering

We will recommend the most suitable system for your cellar and how you want to use it.

Damp FAQs

Can you just plaster over damp?

No. Plastering over a damp wall without fixing the cause and using the right materials leads to the damp coming straight back through.

Is my damp caused by condensation?

If the mould is on the coldest parts of the room, such as corners, behind furniture and around windows, and it is worse in winter, condensation is the most likely cause.

Do you offer damp surveys?

Not at the moment. We can recommend a surveyor and then carry out the replastering.
