Yes — draught-proofing is one of the cheapest efficiency measures with genuine payback: sealing gaps around doors and windows reduces heat loss and cold spots immediately, and typically pays for itself within a heating season or two in an older property.

Brush strips for the door bottom, compression seals and gaskets for the frame edges, letterbox brushes, keyhole covers and external weather bars that deflect rain and wind at the threshold. Most doors leak in more than one place, so combine as needed.

Close the door and measure the daylight gap between door bottom and floor or threshold at both ends (it's rarely even). Choose a brush or seal whose bristle depth comfortably covers the largest measurement — brushes work best slightly compressed.

A weather bar (rain deflector) is an angled strip fixed across the outside face of the door just above the threshold, throwing rain clear before it drives underneath. Essential on exposed doors and a common fix for water creeping in at the threshold.

Yes — self-adhesive and screw-fix options cover both. On uPVC, replacing tired frame gaskets often beats adding surface strips, so check our gasket range if the seals themselves have flattened with age.
