Damp specialists for Altrincham (WA14, WA15)
Altrincham's housing — large detached properties in hale and bowdon, mature semis through timperley, victorian terraces around broadheath, and modern town-centre apartments. — throws up the full range of damp problems. We see rising damp through failed DPCs in older terraces, penetrating damp on solid-brick gable walls, and condensation/mold in poorly ventilated bathrooms and kitchens across WA14.
Every Altrincham damp job starts with a free on-site survey and moisture meter readings. We diagnose which of the three damp types you actually have, treat the cause — chemical DPC, tanking, ventilation or external repairs — then replaster with a salt-resistant render and skim system. One crew, one quote, written guarantee.

Condensation & black mold

Cellar & basement tanking
Cementitious tanking systems and cavity drain membranes turning damp Altrincham cellars into usable, dry space.
