Damp Proofing in Lancashire
In the North of England, older solid-brick and stone properties are common, and exposure to driving rain makes penetrating damp through failed pointing and render a frequent cause alongside classic rising damp.
Damp problems in Lancashire range from a single tide-marked wall to a whole-house condensation issue, so the price is based on what the survey actually finds rather than a flat rate — and for standard domestic jobs the survey and written quote are free.
Across Lancashire we handle everything from rising damp treatment and penetrating damp treatment to condensation and mould control, installing a fresh damp-proof course and salt-resistant damp-proof re-plastering afterwards. Where damp has reached skirtings or joists we add woodworm and timber treatment, and for wet cellars we offer basement waterproofing — every job starting with a proper damp survey so the cause is diagnosed before any work begins.

Damp proofing in Lancashire — frequently asked questions
Will damp proofing be disruptive?
Most single-room DPC and re-plaster jobs take one to three days. There is some dust and mess while old plaster comes off, but we sheet up, work room by room, and clear up as we go so you can stay in the property in most cases.
Do you provide a report for a house sale or mortgage?
Yes. If a mortgage valuation or buyer’s survey has flagged damp, we can carry out an independent specialist damp survey and provide a written report and quote — often what’s needed to keep a sale moving.
What causes penetrating damp?
Penetrating damp comes from water getting in from outside — a cracked render, failed pointing, a leaking gutter, a bridged cavity or a faulty damp-proof course. Unlike rising damp it can appear at any height, and the fix is about stopping the water getting in, not just treating the wall inside.
Can condensation and mould be fixed permanently?
Yes, but it’s about managing moisture and ventilation rather than a one-off treatment. We identify why moisture is building up, treat and remove the mould, and recommend the right ventilation (extraction, PIV units or improved airflow) so it doesn’t simply return.
Do you tank basements and cellars?
Yes — we waterproof basements and cellars using tanking slurry or a cavity drain membrane system depending on the structure and how the space will be used. This is quoted individually after a survey as it varies a lot property to property.
Damp is treated by cause, not by symptom: rising, penetrating and condensation damp look similar but need completely different treatments, which is why every job starts with a proper survey and diagnosis before any work is quoted.
