About

Why protection plastering matters in Manchester

A lot of Manchester housing is solid-wall Victorian or Edwardian terrace with the original DPC long failed, or no DPC at all. We see rising damp, penetrating damp, salt contamination and the blown plaster and black mold that follow. Where damp is the cause, we diagnose properly, treat the source and replaster in one job — not three separate trades blaming each other.

Treatments include chemical damp proof course injection, cementitious tanking slurry for cellars and below-ground walls, salt-neutralising renovation plaster, anti-mold washes and breathable mineral paints. Every job comes with a written guarantee.

FAQs

Protection plastering — common questions

How much does damp proofing cost in Manchester?+

Chemical DPC injection typically runs at £55-£75 per linear metre including replaster, with most terraced rooms coming in between £700-£1,400. Tanking is priced per square metre. Every job starts with a free written survey.

How long until a damp wall is dry?+

After chemical DPC injection, walls dry at roughly 25-30mm per month. A standard 9-inch solid wall is usually fully dry within 6-9 months, with mist-coat decoration safe after 4-6 weeks once the renovation plaster is cured.

Can you treat black mold without ripping plaster off?+

If the mold is purely condensation-driven on sound plaster, yes — anti-mold wash, breathable paint and ventilation advice are usually enough. Where mold has eaten into blown plaster, we hack back, treat the substrate and replaster.
