Basement Conversions in Surrey

If you need basement conversion in Surrey, our team delivers workmanship you can rely on, with no day-rate surprises.

We manage the whole project — design, trades and building control where needed — so you deal with one team. 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 Surrey 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.
