Replastering

Room with beige walls, hardwood floor, a large window with white shutters, and a ceiling light fixture with multiple bulbs.

Damp-related issues often cause visible damage to internal walls, resulting in blown plaster, staining, crumbling surfaces and failed decorations. At London Damp Surveys, we provide professional replastering services as part of an effective, long-term approach to damp remediation.

Where plaster has been affected by damp, it is usually contaminated with hygroscopic salts. These salts continue to attract moisture from the air, meaning that simply redecorating or patching the surface will not resolve the issue.

Specialist Replastering for Damp-Affected Walls

In most cases, damaged plaster must be fully removed and replaced using specialist salt-retardant plaster systems. These systems are designed to:

  • Prevent residual salts from reactivating

  • Allow water vapour to pass through the wall

  • Provide a durable, dry finish suitable for redecoration

Replastering is typically carried out following damp-proofing works, using moisture-resistant mixes that support the long-term performance of the treated wall.

Addressing the Cause, Not Just the Symptoms

Plaster failure is a symptom of an underlying moisture issue. Common causes include:

  • Bridging or absence of a damp-proof course, particularly in older buildings

  • Condensation caused by poor ventilation or occupancy-related moisture

  • Other moisture-related defects identified during a professional damp survey

Our survey-led approach ensures replastering is only undertaken once the cause of damp has been correctly identified and addressed.

Professional Replastering as Part of Damp Remediation

At London Damp Solution, replastering is not treated as a standalone cosmetic repair. It forms part of a structured damp remediation process, ensuring walls are properly treated, protected, and finished to a high standard.

If you’re experiencing deteriorating plaster or signs of damp internally, a professional survey is the first step towards a lasting solution.

Associated Plasterwork & Salt Contamination

After damp-proofing works, salt-contaminated plaster must be removed. If salts are left in place, they can continue to attract moisture from the air, creating the appearance of ongoing damp even after successful treatment.

We replace affected plaster with specialist salt-retardant systems designed to prevent moisture reactivation and ensure a long-lasting, dry finish.
