Basement Conversions in Suffolk

S&K Property Investments & Improvement provides professional basement conversion across Suffolk, backed by a proper survey and a fixed written quote.

You get a straight assessment, a fair fixed price, and work carried out when we say it will be. 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 Suffolk 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.
