Doorsills and Thresholds for Doors

Doorsills and thresholds provide a neat transition between rooms, improve sealing and protect floor edges from wear. Available in a range of materials and finishes, they are essential for both exterior door weatherproofing and interior flooring transitions.

Choosing the right doorsill

Select a doorsill based on traffic, exposure to moisture and the type of flooring. Aluminium and stainless options offer durability and resistance to corrosion for exterior doors, while timber or PVC threshold strips can blend with interior decor. Consider height differences between rooms and any need for ramps or insulation.

Installation and maintenance tips

• Measure accurately: Ensure width and profile match door swing and floor levels to prevent binding.
• Seal properly: Use appropriate sealants to block drafts and prevent water ingress at exterior thresholds.
• Fastening: Secure with compatible screws and hidden fixings where possible for a tidy finish.
• Accessibility: Choose low-profile thresholds for easier wheelchair or pram access if needed.
• Care: Wipe clean regularly and check seals for wear to maintain performance.

A well-chosen doorsill combines function with finish, keeping homes energy-efficient and floors protected while providing a polished boundary between spaces.
