The Complete Service

Proscrew take the installation of foundations for garden buildings and extensions and make them in the words of one of our garden room supplier customers ‘ Vaguely Interesting’ and in our terms, we supply ‘Foundations That Don’t Cost The Earth.’ By mixing these two terms with a genuine desire to make the experience as easy as possible, we hope that the Proscrew involvement with your building will either pass almost unnoticed or be seen as a true enhancement to the overall project.
