Basement Conversions in Tyne and Wear

Looking for basement conversion in Tyne and Wear? S&K Property Investments & Improvement is a trusted local team covering Tyne and Wear and the surrounding area.

We keep sites clean, schedules honest and communication clear from start to finish. A basement or cellar conversion creates space without touching your garden or roofline — ideal in areas where extending out or up is restricted. We convert and, where needed, lower and underpin cellars into dry, warm rooms with proper waterproofing.

Structural waterproofing (tanking + cavity membrane)
Sump, pump and drainage system
Underpinning and lowering where required
Insulation, damp control and ventilation
Electrics, lighting and heating
