Basement Tanking in Durham
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Basement Tanking in Durham is work we take on regularly, and the County Durham housing stock is a big part of why.
County Durham is characterised by stone terraces, former colliery housing and postwar estates, with frost damage to failed render and blown coats on exposed northern elevations the recurring theme on the properties we survey.
Durham sits in a part of the UK that gets cold winters with significant frost cycling — worth factoring into any render decision. Freeze-thaw is the dominant failure mechanism here, so water getting behind render does far more damage than it would further south.
When basement tanking is the right call. Choose tanking for cellar and basement conversions, persistently wet below-ground rooms, and any space you intend to make habitable.

FAQs
Basement Tanking in Durham
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
Can you render over existing render?
Sometimes, if the existing coat is completely sound and well-bonded. We hammer-test it first. Anything hollow has to come off, because covering failure just hides it.
Are you insured?
Yes — full public liability cover, and we can send the certificate before we start. We are happy to provide RAMS for commercial and contractor work.
