Additions and new walls
A wall footing runs as one continuous strip under the wall, spreading its weight along the ground so one soft spot doesn't crack the whole wall above it.
Building a deck, porch or addition, or replacing a post that's sunk? We pour footings that carry the load and keep what's on top level.

Concrete footings are the buried concrete that carries a building's weight down into the ground, and in Somerville we pour them under additions, porches, decks, garages and walls so whatever sits on top stays put.
The price mostly comes down to how much concrete goes in, how much digging it takes and the labor, so a wider, deeper footing on soft ground can cost several times what a shallow one does. The schedule turns on the season and the permit, since the permit comes before the work and cold weather changes how we pour.
We're based in Somerville and work across the cities around it, often on tight lots with little room to dig. I check with the city's building office early, before we settle the plan, then come out, measure, talk it through with you and send an estimate for your own job.
I come out to look at the job myself and stay on it through the pour, so the person who measured your footings is the one watching them go in.
Our crew does the digging, forming, pouring and finishing, and we line up the other licensed trades your job needs, so you're not juggling calls to get a footing in.
Footing work on a tight lot gets messy fast, so we keep the dirt contained and leave the yard cleaner than we found it, with your neighbors still on good terms with you.
The first thing I do is get the dig depth from the local building office, before I price the job or we put a shovel in the ground, because that depth sets how much digging and concrete the job takes. Then our crew digs down to firm, undisturbed ground, since a footing poured on loose fill settles right along with it, and sets the forms so the concrete goes in at the size the plan calls for.
Nobody sees the bottom of that hole once the dirt goes back in, which is exactly why it's where I'd rather spend the time and money. A rough finish on a slab is something you can live with, but a footing that settles takes the wall or the porch above it along. We also check where your roof and yard water runs, because water that sits around a footing softens the ground under it.
When we pour in cool weather, we cover the concrete so frost can't get at it early. If a footing has to go through an existing slab, we do the concrete cutting ourselves, and if an old foundation nearby has already sunk, we talk about foundation raising before pouring anything new beside it.
A wall footing runs as one continuous strip under the wall, spreading its weight along the ground so one soft spot doesn't crack the whole wall above it.
Each post gets its own isolated footing, a single pad or pier poured under it, so the deck or porch doesn't lean as the seasons change.
A thickened slab footing is a slab poured deeper along its edges, where the walls sit, so one pour gives you both the floor and the footing under it.
When a post has sunk or a step has pulled away, the footing under it is usually too shallow or too small, and we dig it out and pour a proper one.
We reply within one business day, and there's no obligation. I come out, look at the job, measure, talk it through with you and then send the estimate.
Tell us where the job is and how many units the building has, because that decides which permit rules apply and who is allowed to file for it.
Let us know if you live there or rent it out, because that changes who files the permit and which contractor registration the job calls for.
Say when you'd like the footings in, because a cold-weather pour costs more to protect and a mild-weather pour may mean waiting, and I'll lay out both.

Straight answers on what footings cost, when they can be poured, how deep they go and what the city asks for first.
Installed concrete footings across the US usually cost about $5 to $20 per linear foot, a national figure for 2026, so treat it as a starting point and check it against a local quote. Where your job lands in that range depends on the size of the footing and the digging. Our estimates are free and done on site.
Usually, yes. Somerville's Inspectional Services Division issues the building permit anyone needs before building, altering, repairing or demolishing a structure. The city's checklist for 1 and 2 family permits asks for a Dig Safe file number, and construction is allowed weekdays 7 a.m. to 7 p.m. and Saturdays 9 a.m. to 7 p.m. When the paperwork is ours, we file it.
You can if you own and live in a 1 or 2 family home in Somerville. For a 3 family or larger building, a licensed contractor has to apply, and they submit their Construction Supervisor License with the application. When the paperwork is yours, we tell you exactly what to bring so nothing holds up the dig.
If the home already exists, you live there and it has one to four units, the contractor must be registered as a Home Improvement Contractor. That's not the same as a Construction Supervisor License, and one can't stand in for the other, so ask to see the supervisor license when you compare bids. We're fully licensed and insured, with satisfaction guaranteed on every job.
Yes, though cold weather adds cost for insulating blankets, tarps, heaters and slower work, which usually buys you the schedule. If nothing's waiting on the footings, I'd usually wait for mild weather. Fresh concrete should be kept from freezing for at least its first 24 hours, even in fall or spring, or it can be ruined or permanently weakened, which is why we cover ours.
Deep enough that frost can't get under the footing, which is how one footing maker's instructions put it. The depth itself comes from the local building officials, so I won't quote you a number off the top of my head. As I said above, I get it from the building office before we price or dig.
Call (617) 284-0921 or use the form, because the sooner I check the dig depth with the city, the sooner you have a real number.
