What affects the cost of door threshold replacement?
Threshold type
A simple aluminum saddle costs far less than an adjustable or full sill-and-threshold assembly under an exterior door.
Condition of the subfloor and sill
Water damage under an old exterior threshold is common and has to be repaired before the new one is bedded and sealed.
Door clearance and sealing
The new threshold has to meet the door sweep evenly, then be caulked and sealed so water doesn't run underneath.
Local labor rates
Rates vary market to market. Your quote reflects what the pro in your ZIP actually charges — not a national guess.
What's typically included?
- Removing the old threshold without damaging the door frame
- Cleaning and checking the subfloor for moisture damage
- Cutting and fitting the new threshold
- Sealing exterior thresholds and adjusting the door sweep
Scope varies by pro — confirm what your quote covers.
What can increase the price?
- Rotted subfloor or sill framing under an exterior door
- Adjustable or ADA low-profile thresholds
- Hardwood or custom-milled thresholds
- Doors that need trimming to clear the new threshold
What can lower the price?
- Simple interior transitions between rooms
- Standard aluminum exterior thresholds
- Bundling with weatherstripping or door adjustments
When should you hire a professional?
An exterior threshold is part of your door's weather seal. If it isn't bedded and sealed correctly, water can get under it and rot the subfloor. A pro also checks for existing damage before covering it up.

How much does door threshold replacement cost?
Our national estimate for door threshold replacement is $120 to $260. This is a planning range from the HandymanQuote national price book, not a guaranteed quote or an average of completed jobs. Enter your ZIP for an estimate based on local contractor pricing where available.
How do I know my door threshold needs replacing?
Drafts, daylight under the door, water getting in, a cracked or loose threshold, or soft spongy wood around the sill are the usual signs.
Is weatherstripping included?
Adjusting the door sweep is often included. Replacing weatherstripping around the whole frame is usually separate, but cheap to add in the same visit.
What if the wood under the threshold is rotted?
Rot repair adds time and materials. Your pro should show you the damage and price it before continuing.
How long does threshold replacement take?
Most take one to three hours. Rot repair or door trimming can stretch it longer.
