Basement Conversions in Norfolk

Professional basement conversion across Norfolk — free survey, fixed written quotes and guaranteed work.

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

Our work is guaranteed, our quotes are fixed in writing, and our tradespeople are vetted and insured. 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.

Our basement conversions service in Norfolk includes

  • Structural waterproofing (tanking + cavity membrane)
  • Sump, pump and drainage system
  • Underpinning and lowering where required
  • Insulation, damp control and ventilation
  • Electrics, lighting and heating
  • Full fit-out and building-control sign-off

Correct tanking and drainage is everything below ground, so we specify a full waterproofing system with a pump and membrane, then insulate, service and finish the space. Every job is designed with structural and building-control input.
