Cracks and gaps in houses can account for 10% to 15% of heat loss. We can assess your home and provide recommendations on where to fix gaps, such as:
-
Fit foam strips around windows and doors
-
Fit seals to gaps around window and door frames
-
Fit covers on exhaust fans which vent straight into the roof (these open when the fan is in use but stop draughts at other times)
-
Fit draught stoppers under doors
