Specialist damp proofing in Withington — chemical DPC injection, tanking, salt-resistant replaster and mold treatment for M20 and the surrounding postcodes. Diagnose, treat and replaster in one job.
Damp specialists for Withington (M20)
Withington's housing — edwardian terraces, semis and traditional south manchester family homes. — 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 M20.
Every Withington 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.
