House Numbers & Mailbox
House number and mailbox installation is the curb-appeal hardware service that mounts exterior address digits on siding, brick, or stucco, and sets curbside mailboxes on plumb pressure-treated 4x4 posts to USPS spec — starting at $100 for a wall-mount number set and $250 for a full post-mount mailbox install. A bronze house-number set bought to match the new front door and still leaned against the garage because the screws in the package are too short for stucco. A mailbox knocked sideways by a snowplow leaning on a rotted post that should have been replaced two winters ago. Every siding material wants a different fastener and a post in the ground has to be set plumb at the right depth so it does not lean inside a year. Handis brings the right anchor for vinyl, lap, fiber cement, brick, or stucco, sets the post in compacted gravel and concrete where it belongs, and gets the work done in 30 to 90 minutes.

How House Numbers & Mailbox Installation Works
Five sequential steps from the substrate check to the USPS-spec mailbox height — the actual sequence on every wall-mount number set and post-mount mailbox install.
Substrate & Fastener Match
Identify the actual exterior surface — vinyl siding, lap, fiber cement, brick, or stucco — and pick the right anchor. Vinyl gets a stainless screw into the stud through a foam shim; brick gets a Tapcon into the mortar joint (never the brick face); stucco gets a self-tapping stucco screw or a sleeve through-drilled. The package screw stays in the bag.
Paper Template Layout
Every digit, plaque, and wall-mount mailbox aligned off a paper template taped level to the wall before the first hole is drilled. Baseline checked against the door header or porch line with a 4-foot level, all holes marked at once. Numbers end up on a single baseline, not stepped a sixteenth-inch each.
Drill & Mount Hardware
Mortar-joint Tapcons on brick, self-tapping screws on stucco, stainless screws into studs on lap or fiber cement, foam-shimmed screws into studs on vinyl. Heads color-matched to the digit or plaque finish. The hardware seats clean without splitting siding or cracking masonry.
Post-Set in Gravel & Concrete (Mailbox Scope)
Pressure-treated cedar or pine 4x4 set 30 to 36 inches deep — bottom 6 inches of compacted gravel for drainage so water drains into the soil rather than rotting the post from the bottom up. Upper third in fast-setting Quikrete concrete. Plumb on two faces with a 4-foot level before the concrete sets.
USPS-Spec Height & Offset Verification
Per USPS Domestic Mail Manual §508, the bottom of the box sits 41 to 45 inches above the road surface and the front face sits 6 to 8 inches back from the curb. Measured off the actual curb at the install location, not the lawn. Carrier reaches the box from inside the truck and the mailbox does not get clipped by a side mirror.
House Numbers & Mailbox Pricing
Final pricing depends on the substrate (siding type, brick, stucco) for wall-mount work and on whether a fresh post hole has to be dug for mailbox post installs. Multi-item visits — house numbers plus mailbox in one trip — are cheaper than two separate visits. Request a free estimate for an accurate quote.

Why Handis for Curb-Appeal Hardware
Most house-number installs we are called to redo were mounted with whatever screw was in the package, and the package screws are sized for an interior softwood. Stucco eats those screws. Brick laughs at them. Vinyl siding splits around them. The fix is the right fastener for the actual material — a self-tapping stucco screw into stucco, a Tapcon into the mortar joint of brick (never the brick face — the brick face cracks and the crack runs), a vinyl-rated stainless screw into the stud through a foam shim that stops the vinyl from buckling. Mailboxes have their own version of the same problem — the cheap pine 4x4 from the orange-box store rots at the ground line in three winters, and the snowplow finishes what the rot started. A pressure-treated 4x4 in concrete with gravel drainage lasts decades.

Customer Reviews
House numbers and mailbox reviews from real Handis customers.
New stucco house, new bronze house numbers. The screws in the package were way too short for our stucco. The tech showed up with self-tapping stucco screws and longer masonry sleeves, paper-template-aligned the digits, and had them up in 40 minutes. Looks intentional and the digits are on a perfect line.
Mailbox post had been leaning since last winter when the snowplow clipped it. The tech pulled the old post (the concrete had cracked at the base and the post bottom was rotted), dug the hole a bit deeper, set a fresh pressure-treated 4x4 in gravel and concrete, and transferred the original mailbox onto a new bracket. Plumb both ways. Two years and it is still straight.
Wall-mount mailbox beside the front door because we are on a no-curbside-delivery street. The brick on the front was 1948 original and the tech drilled into the mortar joints (not the brick face) with a Tapcon. Mailbox is rock solid, no cracked bricks, looks like it was there from the start.
Combo visit — new bronze house numbers above the garage and a new locking mailbox on a fresh post at the curb. Tech did both in one trip in about two and a half hours including the concrete set time. Delivery drivers find us now and the mail does not get stolen.
Cast-aluminum address plaque mounted on brick. The previous owner had hung the plaque off two anchor heads cracked through the brick face. The tech patched the brick face cracks with mortar, mounted the new plaque through the mortar joints, and the plaque is dead level. Hard to find house was the problem; not anymore.
