Damp problems in Edinburgh

The short answer

Damp in Scottish homes almost always has one of three causes: water getting in through the building fabric (penetrating damp), moisture generated inside and not ventilated away (condensation), or moisture drawn up from the ground (rising damp, which is far less common than it is diagnosed). The fix depends entirely on which one it is, so an independent diagnosis before any chemical treatment is the single most useful step.

What is different in Edinburgh

• Solid sandstone walls in pre-1919 Edinburgh property have no cavity, so wind-driven rain on an exposed elevation shows internally as penetrating damp.
• Tenement stair and rear elevations often suffer from shared defective rainwater goods rather than anything inside the individual flat.
• Basement and garden-level flats across the New Town and Stockbridge frequently have raised external ground levels bridging the original construction.
• Modern well-sealed flats in Leith and West Lothian more often have a condensation problem than a structural one.

What the work involves

A proper investigation looks at the outside first — gutters, roof, pointing, ground levels, blocked airbricks — before the inside. Remedies range from clearing a downpipe, repointing, or improving ventilation, through to replastering with a salt-retardant system where masonry has been contaminated.

Rules and consents in Scotland

No warrant is needed for most damp remediation, but replacing plaster in a listed interior, or altering ventilation in a conservation-area elevation, can need consent. Landlords have separate obligations under the repairing standard.

What commonly goes wrong

Paying for an injected damp-proof course on the say-so of a free survey from a firm that also sells the treatment, when the real cause was an overflowing gutter or a raised external ground level.

What it usually costs

Indicative ranges only, to help you judge a quote. They are not an estimate for your property — only the business doing the work can give you that.

• An independent damp and timber report from a chartered surveyor costs a few hundred pounds and often saves several thousand.
• Fixing the external cause — gutter, pointing, flashing — is usually the cheapest remedy.
• Ventilation improvements such as extract fans and vents are modest in cost and address most condensation.
• Chemical DPC injection plus replastering is the most expensive route and is often not the correct one.

What to do, in order

1. 1Photograph the damp patch and note whether it worsens in rain or in cold weather.
2. 2Check gutters, downpipes, pointing and external ground levels first.
3. 3Look at ventilation: extract fans, trickle vents, blocked airbricks, unvented flues.
4. 4Get an independent report from someone not selling the remedial work.
5. 5Fix the cause, then allow the wall to dry before redecorating.
6. 6Recheck the following winter before assuming it is resolved.

When you need a professional

A chartered building surveyor for independent diagnosis, then a roofer, stonemason or plasterer for the actual repair. Use a damp specialist for the works, not for the diagnosis.

Common questions

Will a dehumidifier fix damp?

It manages condensation symptoms but does nothing about water entering through the fabric.

What does damp problems cost in Edinburgh?

Edinburgh labour rates sit above the Scottish average, and access is the other cost driver: tenement stair access, scaffolding on a busy street and parking permits all add to a quote. Get three written quotes for the same specification before comparing prices.
