What this service covers
The bottom seal is the one part of your door that grinds against concrete every single cycle. When it flattens or splits, water, leaves and rodents get in, and the door lands with a bang instead of a soft close.
- U-shape, T-style and bulb astragal seals matched to your retainer
- Aluminum retainer replaced when it is bent, corroded or missing
- Cold-flexible compounds available for freezing climates
- Floor threshold seal offered where the slab is uneven

Bottom Seal Replacement questions
- How do I know which seal I need?
- It depends on the retainer profile on the bottom of your door. Send a photo of the end of the retainer and we will identify it.
- Will it stop mice getting in?
- A fresh seal plus a threshold closes the gap they use. Persistent problems usually mean a damaged corner or an uneven slab.
