FrameSaver delivers all the benefits of wood and composite without limitations. Wood frames wick water, swell, mold and rot. FrameSaver never rots or molds, and the composite bottom won’t wick water or swell. Rot-resistant wood frames delay rot and mold, but fail to prevent it completely. FrameSaver never wicks water, swells, molds or rots. Ever.

Measure the length, width, and thickness of the old threshold, and have a replacement with a similar profile on hand. It should be an inch or two longer than the distance between the door casing’s outside edges so you can trim it for an exact fit later on. Remove the storm door and any weatherstripping attached to the threshold. Tip: You’ll spend ...
Fit a wood-cutting blade, at least as long as the old threshold is deep, into a reciprocating saw. Slice across the wood in two places, about 10 inches from each jamb. Hold the blade so its teeth are nearly parallel to the surface, and watch its tip so you don’t cut the flooring. Stop sawing as soon as you feel the blade cut through the threshold. ...
Stick a flat bar (aka pry bar) between the threshold and the subsill and pry up the center section. Wiggle the ends away from the jambs, if you can, or split them with a hammer and chisel and take them out piece by piece. Use patience and finesse, not brute force; you don’t want to damage the ends of the door stops. Pry off the toekick (the exterio...
A layer of flashing on the subsill prevents water from reaching the framing below. Tom uses Vycor Plus, a rubbery, self-adhering membrane that he cuts to fit between the jambs and a few inches wider than the subsill. The flashing goes over the subsill, adhesive side down, with just enough overhang in front to cover the top edge of the toekick. Afte...
The ends of the new threshold have to be notched to fit around both door jambs. This creates a “horn” that extends under the casing. First, measure the width of the right-hand casing, then hook the tape on the threshold’s back right-hand corner and transfer that measurement to the threshold’s back edge. Next, measure the width of the jamb and stop,...
Cut along the layout lines with a jigsaw or circular saw; finish circular-saw cuts with a handsaw. To mark the cuts for the left-hand notch, measure the width of the opening from jamb to jamb, then hook the tape on the cut-out notch and transfer that measurement to the threshold’s back edge. Mark the width of the jamb and stop on the threshold’s le...
Slip the notched threshold into position under the door stops, then nudge it into place by tapping a hammer on a wood block against the threshold’s edge. Change the block’s position so neither end of the threshold gets too far ahead of the other. When it’s tight to the subfloor, slide pairs of shims—ones cut from cedar shingles are best—under the c...
Squirt expanding foam sealant under the threshold to hold it in place and plug any air gaps. Immediately put the toekick up under the flashing and tight against the underside of the threshold, and screw it to the subsill. Run a bead of sealant between the threshold and each door stop. Finally, protect the wood with deck paint or several coats of sp...
Oct 14, 2023 · Total Time: 3 hours. Skill Level: Beginner. Estimated Cost: $50 to $100. An exterior door threshold takes a lot of abuse from foot traffic and weather—and it can only withstand so much. Door threshold replacement should be done if it's damaged for safety and aesthetics. Thresholds come in wood and metal, with a rubber gasket to seal out the cold.
- 1. The threshold usually fits below the stops and against the jambs. To remove one use a nail set and hammer to poke the nails all the way through....
- 2. Use the old threshold as a template to mark for cutting the new one.
- 3. Test the fit of the new threshold. Apply flooring adhesive to the floor, slip the threshold into place, drill pilot holes, and drive 10d casing...
- 4. Because it is nailed under the jambs, you will have to cut a sill into pieces before removing it. Cut out a large middle section, then chisel or...
- 5. If the old sill pieces are intact, assemble them on top of the new sill stock and use them as a template. However, measure to be sure the overal...
- 6. Tap in the new sill to be sure it fits. Apply flooring adhesive and install the new sill with 12d casing nails.
