Basement Conversions in Thornham

Thornham is a village in Suffolk, in the Mid Suffolk council area, within the IP23 postcode district. It’s around 31 miles north of our base in Thorpe-le-Soken. In the same postcode district we also work in places such as Bedingfield, Braiseworth, Brome and Oakley, Diss, Eye and Gislingham.

Waterproofing your basement

Keeping water out is the most important part of any cellar conversion. Our surveyor will look at the walls, floor and any existing moisture and specify tanking or a cavity drain membrane system so the finished room stays dry.

Planning and finishing the room

Every cellar is different. Yours may need plumbing and electrical alterations, and if it’s going to be used for storage we’ll recommend better ventilation. Once the space is dry we can dry line and insulate the walls so heat stays in and the room is comfortable all year.

Guaranteed and insured

We work closely with Safeguard Europe and the Wykamol Group, and our basement waterproofing is backed by a 10-year guarantee, insurance-backed through Guarantee Protection Insurance Ltd (GPI).
