Basement Conversions in Colchester

Colchester is a city in Essex, within the CO1 postcode district. It’s around 12 miles west of our base in Thorpe-le-Soken. In the same postcode district we also work in places such as Myland and Tiptree.

Waterproofing your basement

Because a basement sits below ground level – and sometimes below the water table – its walls and floor are under constant pressure from water and moisture. Before anything else we waterproof the space, using tanking or a cavity drain membrane system depending on the property.

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).
