Replacement
What Does It Cost to Replace a Mail Slot?
The total cost of a mail slot replacement comes down to two separate questions: what configuration you need, and who installs it. There's no published national cost data specific to mail slots, since it's a small, uncommon enough job that cost-tracking sites don't break it out on its own. This guide uses the closest comparable data available, general small hardware and handyman pricing, alongside what's known about the product itself.
Product Cost Depends on Configuration
The Brass-Seal Forged Brass Mail Slot System is available as an Exterior unit, an Interior unit, or both installed together as a Paired System, in Letter or Magazine size. Current pricing for each configuration is listed on the product page, since it's the source that stays accurate as pricing changes over time. One detail worth knowing upfront: all three finishes, Satin Brass, Satin Nickel, and Satin Black, are priced the same, so finish choice doesn't affect the total.
Installing It Yourself Adds Nothing Beyond the Hardware
Every Brass-Seal system ships with a precision drill template and installs with a standard drill and screwdriver. For a homeowner doing the work themselves, there's no separate labor cost to budget for, only whatever the hardware itself costs. See the DIY vs. professional install guide for what the job actually involves.
Hiring a Professional
For a sense of what comparable small hardware jobs run, Angi's 2026 handyman pricing data puts a typical project between $164 and $649, averaging around $406, with hourly rates generally falling between $50 and $150.1 Angi's separate door repair cost guide notes that repairing or replacing hardware items specifically tends to run $80 to $480 depending on complexity.2 Locksmiths, who also handle some door hardware installation, commonly charge $25 to $150 per item for add-on hardware upgrades like handles or strike plates during a scheduled visit.3
A mail slot replacement, which mounts into an existing opening with basic drilling and doesn't involve frame or lock cylinder work, tends to sit toward the lower end of ranges like these rather than the higher end. Actual pricing still depends heavily on your region, the contractor, and whether the work is bundled with anything else, so a local quote is the only way to know for sure.
What Actually Changes the Total, and What Doesn't
- Configuration: a Paired System involves more hardware and typically more install time than a single Exterior or Interior unit, so expect the total to run higher than installing just one side.
- Door thickness does not typically change the cost. A standard exterior door or thicker works with the included screws. Thickness only affects screw length, not the opening size or the installation approach, so an unusually thick door usually doesn't add to the total.
- Who installs it: DIY adds no labor cost. A handyman or locksmith adds a service call and hourly or per-item charge, as outlined above.
Frequently Asked Questions
Is a mail slot replacement more expensive than installing a lock or deadbolt?
There's no published national data specific to mail slots, but the job is comparable in scope to installing a lockset or deadbolt, drilling into an existing opening, and mounting hardware. General handyman and locksmith pricing for similar small hardware jobs is the closest available reference point.
Does the Paired System cost roughly twice as much as a single unit?
Not necessarily. It involves two units instead of one, so the hardware cost is higher, but installation for both sides in a single visit typically doesn't take twice as long as installing one side alone.
