Local damp specialists · Lancashire
Lancashire's climate, clay soils and Victorian housing stock combine to make damp problems common — and most "damp" jobs need different fixes than people think. We diagnose first, quote fixed-price, and guarantee the work. Sump pumps, waterproofing, damp proofing, condensation. From Preston to Lancaster, Blackpool to Burnley.
We cover the whole of Lancashire — major towns, surrounding villages, and the Fylde Coast. Below is the working list, but it's not exhaustive — if you don't see your town, call us.

Three things make Lancashire homes more vulnerable to damp than the UK average. Understanding which one is hitting your property is the first step to fixing it.
Lancashire is among the wettest counties in England. Lancaster averages around 1,150mm of rain per year — over 50% more than London. Wet ground for 250+ days a year means saturated subsoil pressing against foundations and basement walls, and a high baseline humidity that condensates indoors all winter long.
Most of central Lancashire sits on heavy boulder clay deposited by glaciers. Clay holds water against foundations rather than draining it away, raising the local water table. The Fylde plain (Blackpool, Lytham, Fleetwood) is particularly low-lying with sand-over-clay layers — water runs through the sand and pools at the clay layer, often right at basement floor level.
Lancashire's housing was largely built between 1850 and 1920 to house cotton-mill and coal workers. Victorian terraces, two-up two-downs, and stone-built cottages dominate towns like Burnley, Blackburn, Accrington and Nelson. Most have either no damp-proof course at all, a degraded slate DPC, or a failed bitumen DPC. Cellars were never designed to be habitable — they were coal stores.
If you live in a pre-1920 Lancashire property, you're statistically very likely to have at least one of: rising damp through degraded DPCs, penetrating damp through failing pointing on exposed gables, condensation from poor ventilation in airtight modern retrofits, or a wet cellar from clay-soil water pressure.
The good news: every one of these has a permanent fix, and we've done them all hundreds of times across Lancashire. The bad news: most of the "remedies" sold on social media (anti-mould paint, dehumidifiers, DIY damp-proofing kits) only treat the symptom — leaving the root cause to keep damaging your property.
Step one is always a free, honest survey. We diagnose the cause first, recommend the fix second.
Every Lancashire damp issue we see fits one of these five categories. Click any to read how the fix works and what it costs.
For wet cellars, basement floods, and properties with a high water table (common across the Fylde and West Lancashire). Single-pump systems from £2,000 installed.
Cavity drain membranes (Type C), tanking systems, and full basement conversions. From £3,000 for single-room jobs, £8,000+ for habitable conversions. 10-year guarantee.
Chemical DPC injection for rising damp (most pre-1920 Lancashire terraces need this). External pointing repair for penetrating damp. Replastering with salt-resistant render. From £1,000–£6,000.
Black mould around windows? Streaming windows in winter? That's condensation, not rising damp — and Lancashire's climate makes it worse. PIV ventilation fixes whole-house from £900.
French drains, channel drains, perimeter drainage and soakaways. Especially common on Lancashire properties with heavy clay subsoil where surface water has nowhere to go. From £1,200.
Not sure which of the above is your problem? Don't guess. Our 30-minute survey gives you a written diagnosis and a fixed-price quote on the spot. No obligation, no chase calls.

Three things stack up against Lancashire basements: high annual rainfall (Lancaster averages 1,150mm/year — over 50% more than London), heavy clay soils that hold water against foundations, and a housing stock dominated by Victorian terraces and mill-worker cottages built before modern damp-proof courses existed. Most pre-1920 Lancashire properties have either no DPC, a degraded slate DPC, or a bitumen DPC that has failed. Combine that with a high water table in the lower-lying areas (Fylde, West Lancashire) and you get the persistent damp issues we see every week.
All of Lancashire — Preston, Blackburn, Burnley, Lancaster, Blackpool, Chorley, Accrington, Skelmersdale, Nelson, Colne, Clitheroe, Morecambe, Fleetwood, Heysham, Lytham St Annes, Ormskirk, Rawtenstall, Bacup, Padiham, and every village in between. We also cover the Greater Manchester border (Bolton, Wigan) and Merseyside fringe (Southport area). If you're unsure, call 0800 061 4203 — we'll confirm in seconds.
Single submersible pump systems start around £2,000 fitted, dual-pump backup systems from £3,200. Battery backup adds £650-£950. Lancashire prices are the same as our wider Northern England pricing — we don't charge a "we came from far away" surcharge because we're based locally and travel costs are minimal. Always quoted fixed-price after a free site survey. Full sump pump cost breakdown →
Cavity drain membrane (Type C) systems start at £3,000 for a single-room basement, £8,000+ for a full habitable basement conversion. Tanking systems and external waterproofing are quoted case-by-case after survey. Lancashire's housing stock varies enormously — a Burnley mill-worker cottage cellar is a different job to a Lancaster Georgian townhouse basement — so we always survey before quoting.

Yes. If your basement is actively flooding, call 0800 061 4203 and we'll prioritise your call. We can usually be on-site within hours across most of Lancashire. We bring portable pumps to remove standing water, then survey for the permanent fix once the immediate threat is contained.
Yes — and condensation is a huge issue in Lancashire because of the climate and the older housing stock. We install PIV (Positive Input Ventilation) units that solve whole-house condensation in a single visit. Typical install £900-£1,400, runs for £15-£25 a year, eliminates streaming windows, mould and musty smells. Take our free condensation check → to see if PIV is right for your property.
Usually within 3-5 working days for non-urgent surveys, same-day or next-day for emergencies. Surveys take 30-60 minutes and are free with no obligation. You get a written diagnosis and fixed-price quote on the spot or within 24 hours.
Yes. 10-year guarantees on waterproofing systems, 5-year manufacturer warranty on sump pumps, 2-year on PIV units, and 1-year workmanship warranty across the board. All paperwork is provided in writing — keep it for any future house sale.
