Damp Proofing Oldham
Specialist damp proofing in Oldham — chemical DPC injection, tanking, salt-resistant replaster and mold treatment for OL1 and the surrounding postcodes. Diagnose, treat and replaster in one job.
Damp specialists for Oldham (OL1, OL2, OL4, OL8)
Oldham's housing — stone terraces, hillside semis and former mill-town housing stock. — 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 OL1.
Every Oldham 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.
What we treat
Rising damp in Oldham
Chemical DPC injection through the mortar bed, salt-neutralising render and skim — the long-term fix for failed or absent DPCs in OL1 properties.
Penetrating damp in Oldham
External pointing repairs, render patching and internal tanking where solid walls or failed flashings let water through.
Condensation & black mold
Ventilation upgrades, positive input ventilation and anti-mold treatment for Oldham bathrooms, kitchens and north-facing bedrooms.
Cellar & basement tanking
Cementitious tanking systems and cavity drain membranes turning damp Oldham cellars into usable, dry space.
Salt-resistant replaster
Renovation plaster system over treated walls so the finish stays sound and decoration doesn't fail.
Common questions
Do you treat rising damp in Oldham?+
Yes — chemical DPC injection plus salt-resistant replaster is our most common Oldham damp job. We start with a survey to confirm rising damp versus penetrating damp or condensation before quoting.
How is damp proofing in Oldham quoted?+
It depends on the type and extent of the damp — a single-wall chemical DPC and replaster is very different to full-room tanking. We survey first, then issue a fixed written quote — no day rates.
Is damp work in Oldham guaranteed?+
Yes — chemical DPC treatments come with a long-term written guarantee, transferable on sale of the property. Tanking systems carry their manufacturer-backed warranty.
Do you cover all of OL1, OL2, OL4, OL8?+
Yes — every postcode listed. No travel charges within Greater Manchester.
Why do Oldham homes get damp?+
Older Oldham properties often have solid brick walls, failed or bridged damp courses, raised external ground levels and limited ventilation. Combined with Manchester's rainfall, that is the usual recipe for rising and penetrating damp.
Can you provide a damp report for a mortgage or house sale in Oldham?+
Yes. We provide a written survey report setting out the cause, the recommended treatment and a fixed written quote — the format mortgage lenders and surveyors normally ask for.
How long does damp proofing take in a Oldham house?+
Most single-wall treatments are 2-3 days on site. The salt-resistant render then needs 2-4 weeks to dry before you decorate, using a breathable mist coat first.
Do you remove black mould as well as treat the damp?+
Yes. We treat and remove the mould, then fix the underlying cause — failed DPC, a building defect letting water in, or a ventilation and condensation problem — so it does not come back.
How do I know if I have rising damp or condensation?+
Rising damp shows as a tide mark up to about a metre from the floor with salt deposits; condensation shows as black mould around windows, in corners and on cold external walls. A survey with moisture meters confirms which you have — the treatments are completely different.
How is damp proofing quoted in Manchester?+
After a damp survey we set out the cause, the recommended treatment and a fixed written quote covering the chemical DPC, salt-resistant replaster and any associated work — no vague day rates.
What happens at a damp survey?+
We inspect internally and externally, take moisture-meter readings, check the damp course, ground levels and ventilation, and give you a written report on the cause and the recommended fix.
How long does damp proofing take?+
Most single-wall chemical DPC and replaster jobs take 2-3 days on site. The new render then needs 2-4 weeks to dry out before decorating.
Is damp proofing guaranteed?+
Yes. Our chemical DPC installations come with a written guarantee, and the salt-resistant replaster system is guaranteed against workmanship defects.
Can you get rid of black mould for good?+
Yes, provided the cause is fixed. We treat and remove the mould, then deal with the underlying moisture — a failed DPC, a defect letting water in, or a ventilation and condensation problem — so it does not simply return.
Do I need tanking or a chemical DPC?+
Chemical DPC injection is for rising damp in ground-floor walls. Tanking is a waterproof barrier used for cellars, basements and below-ground rooms under water pressure. The survey tells us which your property needs.
Can you replaster after damp treatment?+
Yes — we always replaster with a salt-resistant system as part of the job, so you get a finished, paint-ready wall rather than a bare treated one.
