§01 — Diagnose
We find the root cause for every damp problem.
We don’t guess. Each Lancashire property is mapped with calibrated moisture meters, thermal imaging and salt-content analysis before we propose a single intervention.
Penetrating Damp
Lateral water ingress through walls, roofs and chimneys – a Lancashire winter classic.
Condensation & Mould
Black-spot mould on cold surfaces from poor ventilation, thermal bridging or lifestyle moisture.
Structural Decay
Wet rot, dry rot, woodworm and timber failure – requiring surgical isolation and treatment.
§02 — Services
A complete damp engineering stack.
From single-room rising damp to full structural waterproofing, every Lancashire-grade service runs through the same diagnostic-first process.

§07 — FAQ
Common technical questions.
How do I know if I really have rising damp?
True rising damp shows tide marks up to ~1m, salt deposits and damp readings above 20% in the masonry. We confirm with calibrated moisture meters and a salt-content test before recommending treatment – many “damp” problems are actually condensation or penetrating damp.
How much does damp proofing cost in Lancashire?
A single-wall chemical DPC typically ranges from £450–£1,200 including re-plaster. Whole-house treatments and structural waterproofing scale with property size. Every quote is fixed and itemised – no surprises.
Is the survey really free?
Yes. Our standard residential damp survey is free with no obligation. Pre-purchase mortgage-format reports for solicitors and lenders are charged separately at a fixed fee.
How long does the work take?
Most chemical DPC injections complete in a single day. Re-plastering adds 2–3 days plus drying time. Larger structural waterproofing projects are scheduled across 1–3 weeks depending on scope.
What is covered by the 30-year guarantee?
All chemical DPC injection and structural treatments are covered by a GPI-insured warranty against treatment failure. The guarantee transfers to future owners — adding documented value to your property.
Which areas of Lancashire do you cover?
All of Lancashire including Preston, Blackburn, Burnley, Lancaster, Blackpool, Lytham, Chorley, Clitheroe, Accrington, Morecambe and the Ribble Valley.
