Basement Tanking in Flint

Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.

Basement Tanking in Flint is work we take on regularly, and the Clwyd housing stock is a big part of why.

Across Clwyd, stone cottages, Victorian seaside terraces and postwar estates dominates, and driving rain and salt exposure on the coastal strip is what we are called out to most often.

With wet with strong exposure along the north Wales coast, specification matters more in this part of the country than a national price list suggests. The north wales coast takes sustained irish sea exposure, and roughcast has protected buildings here for generations for good reason.

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 Flint

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.

Will you need scaffolding?

For anything above single storey, yes — it is safer and produces a better finish than working off ladders or towers. Scaffold is included and itemised in the quote.

How long before I can paint new render?

Through-coloured systems need no painting at all. Sand and cement should cure for around 28 days before masonry paint goes anywhere near it.

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.
