Damp Specialist · Manchester city · M1–M44
Manchester's housing stock spans Victorian terraces in Hulme and Rusholme, mill conversions in Ancoats and Castlefield, Edwardian semis in Didsbury and Chorlton, and modern city-centre flats in Spinningfields. Each has a different damp signature. We diagnose properly, quote fixed-price, guarantee for ten years.
One generic damp fix won't work across Manchester. We diagnose by housing type before quoting.
Hulme · Rusholme · Whalley Range · Longsight · Levenshulme · Gorton · Beswick · Clayton · Crumpsall. Built 1840–1910 for cotton-mill workers. Solid 9-inch brick walls, slate damp-proof course (almost always failed), no cavity. Common issues: rising damp on ground-floor walls, salt staining at skirting, plaster blowing 600–900mm above floor. Fix: chemical DPC injection + replaster with salt-resistant render. From £1,000 — typical single wall up to £6,000 for full property per property.
Ancoats · Castlefield · Northern Quarter · New Islington · Piccadilly Basin. Original 1850s industrial brick. Basements built unwaterproofed for storage. Now converted to habitable space — flat-block laundry rooms, gyms, residential cellars. Always need Type C cavity drain membrane + sump pump system. Irwell/Medlock high water table makes drainage critical. From £4,500–£8,000 per basement.
Didsbury · Chorlton · Withington · Burnage · Heaton Moor. Built 1900–1939 with cavity walls (early cavities), slate or felt DPC. Less common rising damp than Victorian stock — issues are usually penetrating damp through outer cavity, blocked weepholes, or roof / gutter failure causing wet patches mid-wall. Fix is investigative: trace the source, fix it, re-render only what's affected. From £600 typical job.
Spinningfields · Deansgate · NOMA · First Street · Green Quarter. Modern concrete or steel-frame construction. Sealed double glazing. No background ventilation. High occupancy (laundry, cooking, showers indoors). Result: condensation runs the windows, black mould in corners, musty smell — but no rising or penetrating damp. Fix: PIV (Positive Input Ventilation) unit replaces stale damp air with filtered fresh. £900–£1,400 fitted, runs for £15–£25/year.
Manchester city has more pre-1920 terrace housing per square mile than any UK city outside inner London. Cotton-mill expansion 1840–1910 built tens of thousands of identical worker terraces, fast and cheap. Every one was built with a slate DPC. After 100+ years, virtually all of them have failed.
The Irwell, Medlock and Irk all run through Manchester city — partially culverted, mostly invisible at street level, but the water table follows them. Properties in Ancoats, Castlefield, Knott Mill and along Oxford Road sit close to or below river level. High water tables push moisture up through floors and basement walls.
Manchester averages 870mm rainfall per year — the wettest of England's major cities. Combine that with prevailing south-westerly winds driving Atlantic rain straight into solid-walled inner areas (Hulme, Whalley Range, Old Trafford), and penetrating damp through unrepointed brickwork is the second-most-common Manchester problem after rising damp.
Add it together — Victorian terrace stock + three rivers + Atlantic rainfall + dense urban housing — and damp problems are nearly inevitable in older Manchester properties. The good news: every one is fixable, and the diagnostic plus fix usually costs less than people fear.
Step one is always a free, honest survey. We diagnose first, recommend the fix second, never the other way round.

All Manchester city postcodes — M1 through M44. That covers city centre (M1–M4), inner ring (M11–M22), outer city (M40–M44). We frequently work in Didsbury (M20), Chorlton (M21), Withington (M20), Levenshulme (M19), Rusholme (M14), Hulme (M15), Castlefield (M3), Northern Quarter (M4), Ancoats (M4), Crumpsall (M8), Cheetham Hill (M8). If your address starts with M, we cover it.
Manchester has three things at scale: dense Victorian terrace housing in Hulme, Rusholme, Whalley Range and Longsight; a high concentration of converted mill / warehouse properties (Ancoats, Castlefield, Northern Quarter) with original brick basements; and three rivers (Irwell, Medlock, Irk) running under the city raising the water table. Each housing type has a different damp signature.
Yes — one of our most common Manchester jobs. Original mill basements were unwaterproofed storage. Converting to habitable space requires Type C cavity drain membrane, sump system, and managed ventilation. Typical mill-basement waterproofing project £4,500–£6,000+ depending on size and groundwater pressure.
Chemical DPC injection from £1,000 (single wall, typical Victorian terrace) up to £6,000 (whole-property fix + full replaster) typical Victorian terrace. Full damp-proofing (DPC + replastering with salt-resistant render) from £2,500–£6,000 depending on extent. Sump pump installation from £2,000. Basement waterproofing (Type C) from £3,000. PIV ventilation £900–£1,400. No city surcharge — same pricing as wider Greater Manchester.
Yes — Didsbury Village, Victoria Park, Whalley Range conservation area, and several listed properties. Conservation areas constrain external work but most damp fixes are internal (chemical DPC injection, internal cavity drain, sump pumps). We handle planning compliance where needed.
10-year on waterproofing systems, 5-year manufacturer warranty on sump pumps, 2-year on PIV units, 1-year workmanship across the board.
