Professional basement conversion across Monmouthshire — free survey, fixed written quotes and guaranteed work.
Homeowners and landlords in Monmouthshire choose S&K Property Investments & Improvement for basement conversion that is planned properly and finished to a high standard.
Every job starts with a free, no-obligation site survey and a clear, itemised price. 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.
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.
We carry out basement conversion throughout Monmouthshire, including Abergavenny, Monmouth, Chepstow, Caldicot, Usk, Raglan, Magor, Portskewett and the surrounding villages.
