How Many Mailboxes a Crew Installs in a Day

Every community mailbox project reaches the same meeting. The standard is picked, the mockup is approved, the assessment math works, and then someone asks the question that decides eleven other dates: how long will the crew actually be here.

It is a fair question and it deserves a straight answer, including the part most vendors leave out. We do not publish a measured average units-per-day figure, because we do not have one that would mean anything applied to your community. An average across a flat new-construction street in one state and a forty-year-old street with buried footings in another is a number that describes neither. What we can give you is the bracket we schedule inside, the reasons a day lands at the top or bottom of it, and a method for turning that bracket into dates you can publish.

Who installs mailboxes for a whole neighborhood

Before the pace question, the vendor question. Three kinds of companies show up when a board goes looking, and only one of them owns the calendar end to end.

A ship-only supplier sells boxes and posts. Freight arrives on a pallet, sometimes in several shipments, and installation is the association's problem. The board then becomes the general contractor: find a crew, verify they can pour concrete, verify they understand postal placement, and referee the argument if a post leans in year two. Pace is entirely out of the supplier's hands, so no supplier in that model can honestly quote you a per-day figure.

A local handyman or landscape crew can set posts, and some do it well. What they usually cannot do is match a custom box to an existing community palette, produce a spec sheet an architectural committee can vote on, or keep that spec on file so a replacement ordered four years from now still matches street for street. They are also pricing labor by the day, which means their incentive on pace runs the opposite direction from yours.

A design-build-install vendor carries all three functions. That is what we do. We are a family founded, USA based maker headquartered in South Florida that serves communities nationwide. The team that drew the mailbox knows what it weighs, what base it needs, and how long it takes to set, which is why we are willing to commit to a phase window at all. There is a longer breakdown of the vendor structures in our guide on who installs mailboxes for an entire HOA community.

The planning range, and how to read it

Here is the bracket, stated as what it is: a planning range used to build a schedule, refined after a site walk on your specific streets.

• Upper end, roughly 15 to 20 units per crew day. New posts going into fresh holes. No demolition. Homes on standard frontage so the crew moves a short distance between sets. Boxes arrived with numbers already applied. Street parking light enough to stage the truck near the work.
• Middle, roughly 10 to 15 units per crew day. Mixed conditions, which is most communities. Some existing posts come out easily, others fight. A few addresses need a height correction because the street was resurfaced at some point. Some numbering happens on site.
• Lower end, roughly 5 to 10 units per crew day. Full removal of old concrete footings with haul-off. Tight access, long private drives, or gated sections with limited entry windows. Pillar or extra-large units, which are heavier and need a more substantial base. Rock, roots, or irrigation in the hole.

Those brackets exist because the work is not repetitive in the way the count implies. Twenty mailboxes is twenty small concrete jobs in twenty different pieces of ground. The mailbox itself is the most predictable part of the day.

Why it is a range, not a promise

Six variables do most of the damage to a fixed daily figure. A board that understands them can read two competing bids far more accurately, because the bid that quotes an exact number per day is usually the bid that has not walked the site.

Whether the old posts are coming out

This is the single largest swing, and it is invisible from the curb. A post that was set properly decades ago sits on a mass of concrete below grade. Getting it out means breaking that up, pulling it, hauling it off, and backfilling before the new hole can even be dug in the right place. A post that was tamped into dirt comes out in a few minutes. Two streets in the same community can be built both ways, by different subcontractors, in the same year.

We also reset and replace existing aging posts as a service, and when a post is worth keeping we will say so even though it is the smaller job. That decision changes the schedule as much as it changes the invoice.

What the soil is doing

Sand digs fast and holds a hole poorly. Limestone or coral rock under a few inches of fill stops a shovel outright. Heavy clay comes out in a single stubborn plug. Mature root systems along an established street mean hand digging around a trunk instead of a clean cut. None of this appears in a photo, and all of it is per hole, so it multiplies straight through the unit count.

Spacing between homes

A community of duplex pairs with two boxes near one shared frontage is a different day than a community of wide lots where the crew relocates the truck for every set. Cul de sac bulbs concentrate several addresses in a short arc, which helps. Long frontages with the box far from a staging point do not. Two communities with identical door counts can sit two full working days apart on this variable alone.

Access

Gate codes, guard house sign-in, and delivery windows all cost time at the start of a day. Resident vehicles parked at the curb are the common one: a car in front of an address means either a knock, a wait, or a return trip. Narrow streets with no shoulder force the crew to shuttle material by hand. A board that sends a real notice letter ahead of the crew buys back more schedule than most people expect, which is the practical argument in our guide to scheduling a community mailbox install without disrupting residents.

Weather

Concrete has opinions about rain and heat. A wet morning can push the start, and a heavy afternoon storm can end a day early with holes open. In South Florida during the wet season, a schedule with no float days built in is not a schedule, it is a wish. We plan float days into a phase rather than pretend they will not be needed.

Whether numbers go on in the shop or on site

Numbers run 5 to 12 inches, and where they get applied matters to the daily count. When each box is numbered before it ships, the crew sets a finished unit. When numbering happens on site, that is a per-unit step added to every single address, plus a verification pass against the community's address list because an incorrect house number is the one error residents notice immediately. Same total labor either way. Different effect on the install-day number, which is the number your calendar is built from.

The placement standard is published in the Domestic Mail Manual, section 508, and it is measured from the road, not from the grass or the sidewalk. In an older community the reference surface has often moved. Streets get resurfaced and the road comes up. Swales settle and the grade drops. Boxes nobody touched drift out of the window on their own, and a community replacement is usually the moment all of that gets corrected at once. We cover the measuring method in getting every mailbox in the community to the same height.

Turning the range into a calendar a board can publish

The arithmetic is simple once you accept the range instead of fighting it. Take 180 homes. At 10 to 20 units per crew day, one crew is somewhere between nine and eighteen working days on site. That spread looks uncomfortable written down, and that discomfort is the honest information.

What to do with it:

• Publish the conservative end to residents. Announcing eighteen days and finishing in twelve makes a board look competent. The reverse generates emails to every director.
• Add crews to compress the span, not the variance. Two crews roughly halve the calendar. They do not make the ground more predictable, so the buffer stays.
• Sequence by street and notice per street. Residents do not need the whole program schedule. They need a two day window for their own address. Street-level sequencing is what makes that possible.
• Keep the build window separate from the install window. Our mailboxes are made to order after a mockup is approved, with a lead time of about 2 to 3 weeks standard, longer for LED or vault models. Installation cannot begin before the units exist. Boards that collapse those two windows into one number are the boards that end up sending a correction.
• Hold float days at the end of each phase. Rain, a locked gate, an address with something unexpected in the hole. One or two per phase absorbs nearly all of it.

What one crew day actually contains

It helps to see where the hours go, because the per-day count is a byproduct of a fixed sequence repeated per address, not a rate that can be pushed.

The day starts with staging: material off the truck, the run of addresses confirmed against the sequence, utility and irrigation locations noted. Then, at each address, the crew marks placement against the curb face, digs to roughly two feet, places a 4-inch footer at the bottom, sets the post in concrete, brings the box to the correct height while the mix is still workable, checks plumb from two directions, confirms the house number is the right one for that address, and finishes the base with a decorative rock bed. Cleanup follows at the end, along with a walk of the day's addresses.

None of those steps disappear at volume. The efficiency of a community program comes from somewhere else: the crew is already on the street, material is already staged, the measuring method is already dialed in from the first few sets, and the spec does not get re-litigated at each house. That is real, and it is why a per unit community price beats twenty individual installs. It is not the same thing as the work per hole getting faster.

What we will commit to, and what we will not

We will commit to a phase window, a crew count on site, a sequence by street, and the install tier for each address. We will commit to the placement standard at every unit and to the spec sheet your board and architectural committee approved.

We will not commit to a fixed number of units per day, and we would treat any vendor who does with some suspicion. The honest tradeoffs are worth stating plainly: our pricing is premium, and because every unit is made to order after mockup approval, there is a real lead time before a crew can start. What you get for that is one company accountable for the design, the build, and the ground, with the approved spec on file so a replacement ordered years from now still matches the street.

Two requirements, not one

One last thing that surprises boards mid-project. USPS placement rules and your architectural standard are two separate requirements, and both have to be met. The architectural standard governs material, color, and appearance. USPS governs where the box sits: 41 to 45 inches from the road to the bottom of the box, 6 to 8 inches of setback. A mailbox can satisfy the architectural standard perfectly and still sit too low for a carrier to reach from the vehicle. Catching that at install, while the concrete is wet, costs nothing. Catching it after a phase closes out means going back.

If you want a real window instead of a range, the fastest path is a site walk. Send us the community name, the door count, and whether the existing posts are coming out, and we will walk the streets and give you dates your board can put in writing.
