Curb Appeal & Addressing
House Number & Mailbox Installation Done Right
A mailbox leaning toward the street, house numbers mounted crooked, or a post that wobbles when you open the door — these details are small but they’re the first thing visitors, delivery drivers, and emergency services see when approaching your home. Getting them right takes the right hardware and the right installation method for the substrate.
NorTech installs post-mount mailboxes with posts properly set in concrete, wall-mount mailboxes on any exterior surface including brick, stucco, and vinyl, locking mailboxes positioned to USPS compliance standards, and house numbers and address plaques anchored level and visible from the street. We carry standard hardware for all common substrates on every truck.
You supply the mailbox and address hardware. We handle the installation. Written estimate before any work begins.
All Services
Every Mailbox & Address Installation We Handle
From a single house number to a full mailbox post replacement — here’s every service we provide and what it involves.
Post-Mount Mailbox Installation
New post dug and set in concrete, backfilled, and allowed to cure before the mailbox is mounted. Post positioned at the correct height and setback per USPS guidelines. Includes standard wooden or metal post installation for any standard residential mailbox.
Post set in concrete
Mailbox Post Replacement
Old post removed, existing concrete footing broken out, new post set in fresh concrete at the correct height. The most common mailbox service call — rotted wood posts are the leading cause of leaning mailboxes.
Remove old, reset new
Wall-Mount Mailbox Installation
Mailbox mounted directly to the home’s exterior wall, column, or fence post. Fastening method depends on substrate — wood, vinyl, stucco, brick, and masonry each require different hardware. Mounted level and anchored into structure, not just surface material.
Any exterior surface
Locking Mailbox Installation
Post-mount or wall-mount locking mailboxes installed to USPS compliance standards. Positioned at the correct height and location for carrier delivery access. Available in pedestal and through-the-slot locking designs.
USPS compliant positioning
House Number Installation
Individual address numerals mounted level and spaced correctly on the facade, garage, or address column. Substrate-appropriate fasteners used for wood, vinyl, brick, stucco, and masonry. Positioned for maximum street visibility per local addressing guidelines.
Level, spaced, street-visible
Address Plaque Installation
Engraved, cast, or printed address plaques mounted to walls, columns, or dedicated mounting panels. Heavier plaques require substrate anchoring rather than adhesive mounting. We assess the plaque weight and substrate during the quote.
Wall, column, or panel mount
Mailbox Post Installation
How a Mailbox Post Should Be Properly Set
Most leaning or failed mailbox posts come down to one thing — the post wasn’t set in concrete, or the concrete wasn’t mixed and placed correctly. Here’s how we do it right.
Dig to Correct Depth
Post hole dug 18–24 inches deep — or below the frost line in cold climates — to prevent seasonal heaving that causes posts to lean over time.
Set Post Plumb
Post set perfectly vertical using a level on two faces before concrete is poured. A post set even slightly off-plumb looks noticeably crooked once the mailbox is mounted.
Pour & Brace
Concrete mixed to proper consistency and poured around the post. Post braced in position until the concrete sets — fast-setting concrete allows same-day mailbox mounting in most cases.
Crown the Top
Concrete surface crowned slightly above grade and sloped away from the post to shed water. Water pooling against the post base is the primary cause of wood post rot.
Mount at Correct Height
Mailbox mounted so the bottom of the box is 41–45 inches above the road surface — the USPS standard for carrier access without requiring the carrier to exit the vehicle.
Setback from Road
Post positioned 6–8 inches back from the face of the curb — far enough to avoid vehicle strikes but close enough for carrier access per USPS guidelines.
USPS Installation Standards
USPS Mailbox Placement Requirements We Follow
Every mailbox installation we complete meets USPS Postal Operations Manual guidelines. Here are the key requirements that determine whether your mail gets delivered reliably.
Box Height
Bottom of mailbox opening must be 41–45 inches above road surface to allow carrier access from the vehicle.
Road Setback
Post positioned 6–8 inches from the face of the curb or road edge for safe carrier access and to avoid vehicle contact.
Locking Mailboxes
Must be STD-4C compliant or have an approved parcel locker if used for package delivery. Opening size must meet carrier access requirements.
Identification
Address or box number must be displayed on the mailbox in minimum 1-inch high letters, visible to approaching carriers.
Requirements may vary slightly by local post office and delivery route type. We confirm placement standards for your specific address during the on-site quote.

What Affects the Cost of Mailbox & House Number Installation?
These are quick jobs by most standards — here’s what moves the quote up or down.
Wall-mount installation is faster — typically 30–60 minutes. Post-mount installation with concrete setting takes 1–2 hours of active work plus cure time. If old post removal and footing demolition is required first, add additional time. We quote both scenarios clearly before scheduling.
Wall-mount on wood or vinyl is the fastest substrate. Brick and masonry require hammer-drill anchors and add time. Stucco requires careful drilling and post-installation patching to seal penetrations. Each substrate is assessed and quoted during the on-site visit.
Replacing an existing post requires removing the old one — which may involve breaking out an existing concrete footing. Concrete footing removal is labor-intensive if the footing is large or deep. We assess the existing installation during the quote and factor removal into the estimate.
Individual house number installation is quick — typically 20–40 minutes for a full address set. Adding an address plaque or installing numbers in multiple locations (front door and garage, for example) adds modest time. Bundling mailbox and house number installation in one visit is the most cost-effective approach.
Every job starts with a full on-site diagnostic. You receive a complete written estimate before any work begins.
Customer Reviews
What Homeowners Say About Our Mailbox & Address Installations
“Post-mount mailbox replaced — old one had been leaning for two years. New post is perfectly plumb, set in concrete with a proper crown to shed water. Looks completely different from the street.”
— Celestine O.“Wall-mount locking mailbox on a brick column. Anchors set into the mortar joints, sits perfectly level, and the penetrations are patched cleanly. Quick job done very professionally.”
— Aurelio F.“House numbers plus mailbox post in one visit. Numbers are level and the spacing is even — something that’s harder than it looks to get right. Very happy with how the front of the house looks now.”
— Wanjiku P.“Tech broke out the old concrete footing, set the new post with fast-setting concrete, and mounted the mailbox same day. Correctly positioned per USPS height requirements. Efficient and knowledgeable.”
— Rashida C.“Address plaque on stucco — drilled carefully, anchored solidly, and the holes around the mounting hardware are sealed. No damage to the stucco surface. Clean install.”
— Tomasz B.“Had the old mailbox and post removed and a new post-mount locking box installed. The tech confirmed the USPS height before setting the post. Carrier has had no issues with access since.”

House Numbers & Mailbox Installation — Common Questions
Straight answers on post setting, USPS requirements, locking mailboxes, and what to expect.
NorTech installs post-mount mailboxes with post set in concrete, wall-mount mailboxes on any exterior surface, locking mailboxes, address plaques, and house numbers. We handle the full installation including post setting, surface anchoring, level alignment, and hardware finishing. We do not supply mailboxes or address hardware — customers supply their own product and we handle the installation.
USPS guidelines recommend mailbox posts be set at a depth that keeps the mailbox opening 41 to 45 inches above the road surface. Standard residential mailbox posts are set 18 to 24 inches into the ground, with the post bottom surrounded by concrete to prevent movement. In frost-prone areas, posts should be set below the frost line to prevent heaving.
Yes. Wall-mount mailbox installation on brick, stucco, or masonry uses hammer-drill anchors set into the substrate. Stucco requires careful drilling to prevent surface cracking. We patch and seal around all penetrations after installation to maintain the wall’s weather barrier.
House numbers should be visible from the street and positioned so emergency services can identify the address quickly. Numbers are typically mounted at eye level near the front door or garage — 4 to 6 feet above grade — or on the curb-facing facade. Local codes vary; some municipalities specify minimum number height and contrast requirements. We position numbers for maximum street visibility during installation.
Yes. We install both post-mount and wall-mount locking mailboxes. Locking mailboxes must comply with USPS size and access requirements if they are to receive carrier-delivered mail. We confirm USPS compliance during the installation and position the mailbox at the correct height and location per postal service guidelines.
A wall-mount mailbox installation takes approximately 30 to 60 minutes. A post-mount installation with post set in concrete takes 1 to 2 hours, plus concrete cure time before the mailbox can be mounted — typically 24 hours. We can mount the post and return to install the mailbox once the concrete has set, or use fast-setting concrete to complete the job in one visit.
Mailbox installation typically does not require a building permit. However, mailboxes must meet USPS installation standards regarding height, placement relative to the road, and clearance for mail carrier access. Homeowners in HOA communities should also check community guidelines for approved mailbox styles and colors before purchasing.
Yes. We remove the old post, clear the existing concrete footing if present, set a new post in fresh concrete, and remount the mailbox. Rotted wood posts are the most common mailbox failure — replacing the post and resetting it in concrete is the correct long-term fix.
We install individual mounted numerals in metal, brass, bronze, and plastic, illuminated address numbers, engraved or printed address plaques, and curb address painting stencils. We work with whatever style the homeowner has purchased. Mounting method varies by substrate — wood, vinyl siding, stucco, brick, and masonry each require different fasteners.
Yes. All mailbox and house number installations completed by NorTech are covered by our 1-year labor warranty. If a mounting fails, a post shifts, or numbers come loose due to installation defects within 12 months, we return and correct it at no charge.
