Holyhead, Gwynedd
Basement Tanking in Holyhead
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Basement Tanking in Holyhead is work we take on regularly, and the Gwynedd housing stock is a big part of why.
The prevailing picture in Gwynedd is slate and stone cottages, quarry housing and exposed coastal properties. That means extreme driving rain on slate and stone construction comes up more here than almost anywhere else.
With among the highest rainfall in the UK with severe exposure, specification matters more in this part of the country than a national price list suggests. Snowdonia records some of the highest rainfall in britain, and any non-breathable render on stone here will trap water within a single winter.
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 Holyhead
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.
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.
