Basement Tanking in Cumbria
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Basement Tanking in Cumbria is work we take on regularly, and the Cumbria housing stock is a big part of why.
The prevailing picture in Cumbria is traditional slate and stone construction, lakeland cottages and exposed rural properties. That means driving rain, saturation and moss growth on north-facing walls comes up more here than almost anywhere else. Local conditions bring the highest rainfall in England, and that has a direct bearing on which systems are worth specifying.
Local factor. With the wettest conditions in england, breathability is not optional — sealing a cumbrian stone wall in cement causes damage within a few winters.
Is basement tanking right for a Cumbria property?
Choose tanking for cellar and basement conversions, persistently wet below-ground rooms, and any space you intend to make habitable.
That decision gets made at the survey, not on the phone. We will tell you plainly if a different system would serve the building better — including when a cheaper one would.

FAQs
Basement Tanking in Cumbria — questions
Do you take a deposit?
For most domestic jobs we take a deposit to cover materials and scaffold, with the balance on completion. Terms are set out clearly in the written quote.
Can you match my existing render?
Usually, yes. We colour and texture match as closely as we can, though weathered render never matches a fresh batch exactly — we will be honest about how visible a patch will be.
Can any cellar be tanked?
Most can, but the right system depends on water pressure, structural condition and intended use. A survey establishes which approach is appropriate.
How long does basement tanking last?
A correctly designed and installed system carries a 20-year warranty. Type C systems need periodic pump servicing to maintain that.
How long does a rendering job take?
A typical three-bedroom semi is usually one to two weeks on site including scaffold, preparation, application and finishing. Weather, wall condition and the system chosen all move that.
Do I need planning permission to render my house?
Usually not on a standard house, but you will if the property is listed, in a conservation area, or if rendering would significantly change its appearance. We flag it at survey.
