The bigger basement conversion costs can be caused by the bespoke customer requests.    
Some cellars will have strange building features that make the cellar tanking process more difficult.    
We usually charge £75 for a local Triton Isola Platon cellar annual sump pump inspection and around £75 for a limestone wash.

Services ensure that the pump and drainage system are clear and
that the water management system will continue to operate as it was designed to.
