Draught Seal & Restore

Draught Seal & Restore is our core door repair & recondition service and should be considered an essential upgrade for all existing period doors.

Our recondition and draught seal service will restore your hereitage doors and french windows to proper working order, stopping rattles and controlling those intrusive cold draughts.  By controlling the draughts we also reduces the airborne noise & dust being carried into your home.

Our draught seals can be machined into the timber components to become an integral, practically invisible part of the window. Our Draught Seal & Restore Service is ideal for conservation areas and listed buildings.
