Cellar And Basement Conversions In Sheffield And Chesterfield.

Our core business is basement conversions. We provide an initial free survey and estimate. When you choose The Basement Company to carry out your work, we produce a detailed quotation and a full set of CAD drawings for your approval.

Our quotation is fixed. Unlike anyone else, we are in a position to fix our price due to the detail we put into our quotation and drawings. Should you, as the client, ask for additional work once we have started, we will agree upon and price and scope of the work before we carry it out. This way you can be certain to know what your final basement cost will be, and not lose control of your budget, or have any nasty surprises.

During the basement or cellar construction process, several waterproofing and damp proofing measures will be taken.

These include:

  • A concrete foundation.
  • A concrete underlying surround.
  • Water resistant and salt resistant adhesives.
  • A Damp proofing course in the walls. ( DPC Injection )

A Pool And Bar Basement Conversion.

A Converted Basement In A Beautiful Victorian House.

The Basement was used (as in most cases) as a storage area. The electricity meter had to be moved to make way for a new access staircase and opening for a pair of oak French doors.

To the front of the property the garden way lowered slightly to allow us to cut out several new windows at the basement level. Hand crafted stone mullions and cills were fitted by out master stone mason. He also created the new stone walls and steps after it had been excavated and strengthened with concrete piles, beams and foundation blocks.

The basement was waterproofed using Delta Membrane throughout and a Delta single sump for the kitchen grey water and a Delta foul sump for the bathroom waste.

The heating supplied was Warmup’s electric in screed cable, finished with Cemex Supaflo screed to provide a superb level floor.

After plastering throughout, solid oak doors and engineered oak flooring was fitted along with an oak Magnet kitchen. We installed a premium bathroom suite fully tiled throughout in grey travertine Our professional decorator completed the works to create yet another beautiful home.
