Door Bottoms to Seal and Quiet Doors

Door bottoms are an effective, low-cost way to improve insulation, reduce drafts and minimise noise under doors. Available in various profiles and materials, they are suitable for internal and external doors, including commercial thresholds.

Why fit a door bottom

Installing a door bottom helps keep heat in and cold out, cuts down on dust ingress, and prevents smoke and fumes from spreading between rooms. Some models include brush strips to keep out insects, while others feature rubber seals for water resistance on exterior doors.

Selection and installation advice

• Measure door clearance and thickness to choose a compatible profile.
• Decide between fixed trims that screw to the door and automatic drop seals that engage when the door closes.
• For uneven floors, flexible silicone or brush options accommodate gaps without scraping.
• Consider finishes that match existing hardware for a discreet appearance.
• Regularly check screws and seals and replace worn strips to maintain performance.

Look out for clearance items or surplus stock when fitting multiple doors to reduce costs on larger projects. Properly selected door bottoms improve comfort and energy efficiency while delivering a tidy, professional finish to your doors.
