How To Caulk The Outside Door Sill?

The door sill, or threshold, is the bottom portion of your exterior door frame and helps keep elements out and provides a seal. It wears over time, and it’s essential to have a flexible, secure seal on the bottom of your doors to keep the outside air and bugs out without making the door hard to close. To replace a damaged door sill, pull the rubber gasket out of the grooves on the metal threshold, remove the screws holding the metal threshold in place, and cut the rotten door sill into pieces using an oscillating tool or circular saw.

To seal around the exterior of a door properly, follow these three simple methods: clean the subfloor, check for humps, use primer/adhesive for the tape, use a good quality silicone or urethane, use a piece of metal flashing to cover the bricks, tuck it under the door most of the time, and seal it with polyurethane caulking to the door threshold. The sill and stone below it should be arranged so water flows away. If the gap bridging interior to exterior is sealed, fill the space with an insulator rather than something that conducts heat moderately.
