Step By Step Guide

Cementitious Waterproofing: This is where a cementitious slurry is applied to the walls and the floors to stop any water entering the cellar. 

Cavity Drainage System: This consists of plastic membranes being installed in the walls and floors and a drainage channel is installed around the perimeter of the chamber that leads to a sump where the water is pumped out of the cellar. 

Insufficient headroom in your cellar? It is sometimes possible to lower the cellar floor. As experienced basement conversion specialists, we carry out all the necessary inspections alongside Building Control before any work has commenced.

The cellar will need to be provided with suitable escape routes in case of a fire. A mains operated smoke detection system will need to be installed. Fire doors and frames will be required to seal the cellar either at the top or the bottom of the stairs.

Walls and ceilings will be plasterboard and skimmed for the perfect finish ready for decoration. Ceilings need to offer 1 hour fire protection. The floors will be finished with 18mm moisture resistant boards allowing you to choose whatever overlay you require.

The most effective way of basement heating installation is to extend the existing central heating system. Our heating engineers will ensure your existing boiler has sufficient capacity to accept any additional radiators.  All new radiators will be fitted with thermostatic valves to control the room temperature.

Where natural ventilation is not practical a mechanical ventilation system will need to be installed. 

The walls and floor of your cellar will be  lined with insulating boards and the windows will include 24mm double glazing units. 

You are likely to require some electrical alterations as part of your conversion. We ensure that our electricians are able to issue you with BS7671 test certificates when they have completed their installation as these will be required before your Building Regulations Completion Certificate can be issued.
