Garage conversion guides

Do garage conversions need damp-proofing?

This is one of the most common issues we find during a garage conversion survey, and it needs addressing properly before any finishing work starts.

Why it's an issue

Garage floors often sit below the damp-proof course of the main house, since garages weren't originally built as habitable space. Left unaddressed, this can lead to persistent damp in the converted room.

How it's fixed

Damp-proofing typically involves raising the floor level, installing a proper damp-proof membrane, and addressing any damp-proof course issues in the walls. This is assessed during the survey and priced into the conversion from the outset.

How do I know if my garage has a damp problem before converting it?

We check for this as part of the survey, looking at floor level relative to the damp-proof course and any visible signs of damp in the walls.
