Basement Conversions in Powys

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

S&K Property Investments & Improvement carries out basement conversion throughout Powys — one accountable team from first survey to final finish.

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 Powys 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.
