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.

What Does a House Numbers and Mailbox Install Include?
A house numbers and mailbox install is the residential curb-appeal service that mounts exterior address digits and curbside or wall-mount mailboxes with the right fastener for every common siding and masonry surface — vinyl, lap, fiber cement, brick, and stucco — starting at $100 for a six-digit wall-mount number set. The visit breaks into wall-mount house number sets, post-mount mailbox installs (with a fresh 4x4 cedar post set plumb), wall-mount mailbox installs near the front door, and address plaques that combine the number set with a backing plate.
Wall-Mount House Number Set
Individual numerals or a combined number plaque mounted on the front of the house beside the door, on the porch column, or above the garage. Substrate decides the fastener — vinyl siding takes vinyl-rated stainless screws into the stud through a foam shim, lap or fiber cement takes a stainless wood screw, brick takes a Tapcon or masonry sleeve into the mortar joint (never into the brick face), stucco takes a self-tapping stucco screw or a masonry sleeve through-drilled. Numbers come off the wall paper-template-mounted so every digit is on the same baseline. About 30 to 45 minutes per set.
Post-Mount Mailbox Install
Fresh pressure-treated cedar or pine 4x4 post set in the ground at the curb, with the mailbox mounted to a USPS-rated bracket on top. USPS specs (Domestic Mail Manual §508) call for the bottom of the box to sit 41 to 45 inches above the road surface and the front face to sit 6 to 8 inches back from the curb face. The post sets 30 to 36 inches deep, with compacted gravel at the bottom for drainage and concrete (fast-setting Quikrete) in the upper third for stability. Plumb checked on two faces before the concrete sets. About 90 minutes plus 1 hour for the concrete to firm up.
Wall-Mount Mailbox Install
Wall-mounted mailbox beside the front door (for non-curbside delivery). Mounted at the standard 41 to 45 inch height on the side of the house adjacent to the door, with stainless screws into studs whenever the studs line up or into rated heavy-duty toggle bolts when the box has to land between studs. About 30 to 45 minutes.
Address Plaque with Backing Plate
Larger house-number assemblies — a backing plate (cast aluminum, slate, or wood) with the numerals mounted to it, then the plate mounted to the house as a single unit. Often used when the front of the house is brick or stucco and individual numbers would be hard to align. Paper-template-mounted on the plate before the plate goes up. About 45 minutes.
Mailbox Post Replacement (Existing Mailbox)
The classic snowplow scenario — the mailbox is fine, the post is rotted at the ground line and leaning. Old post pulled (concrete dug out where it has set), fresh 4x4 set in the same hole at the right depth, existing mailbox transferred to the new post. About 75 minutes plus concrete set time.
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.
Right fastener for the actual siding or masonry
Vinyl siding gets a stainless screw into the stud through a foam shim. Lap or fiber cement gets a stainless wood screw long enough to reach the stud. Brick gets a Tapcon or masonry sleeve into the mortar joint, never the brick face (the brick face cracks and the crack runs). Stucco gets a self-tapping stucco screw or a masonry sleeve through-drilled into the wood substrate behind. The package screw stays in the bag.
Paper template before the first hole
Every digit, every plaque, every wall-mount mailbox aligned off a paper template laid out level on the wall before the first hole. We tape the template, double-check the baseline against the door header or the porch line, then mark all the holes at once. The template comes off, the holes get drilled, the hardware goes up. Numbers end up on a single baseline, not stepped a sixteenth-inch each.
USPS-spec mailbox height and offset
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 face. We measure off the actual curb at the actual install location, not off the lawn or the driveway. Carriers do not have to leave the truck and the mailbox does not get clipped by a side-mirror.
Mailbox post set in gravel-and-concrete for drainage and lifespan
Pressure-treated cedar or pine 4x4 set 30 to 36 inches deep. Bottom 6 inches is compacted gravel for drainage (water that pools at the bottom of the hole rots the post — gravel lets it drain into the soil). Upper third is fast-setting concrete (Quikrete Fast Setting Concrete Mix). Plumb on two faces before the concrete sets, then a 60-minute cure before the mailbox goes on top. Lasts decades.
Insured, background-checked, 30-day workmanship guarantee
Every Handis handyman is insured and background-screened. If a house number we mounted comes loose, an anchor pulls out of siding or masonry, a mailbox post leans within 30 days because of how we set it, or a wall-mount mailbox shifts, we come back and fix it at no extra charge. The guarantee covers our work — it does not cover damage from a snowplow hit, a tree falling on the post, or a tornado.

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.
