Somerville winters push shallow footings out of the ground in a few seasons. We dig to the 48-inch frost depth required for this climate, pour reinforced concrete, and handle every permit and inspection so your deck, porch, or addition stays solid.
Concrete footings in Somerville involve digging to approximately 48 inches below grade, setting steel reinforcing bars inside wood or tube forms at the required depth, passing a city inspection before any concrete is poured, pouring the footing, and removing the forms once the concrete sets — most residential jobs take one to two days on site, with a week of curing before framing can begin.
The depth requirement is not bureaucratic formality. It reflects where the ground actually freezes in a typical Somerville winter. A footing poured too shallow will be pushed upward by frost every year until the structure above it cracks, tilts, or pulls away from the house. In a city where most homes are over 80 years old and were built before modern footing standards, this kind of movement is one of the most common structural problems contractors encounter. Whether you are building new or reinforcing existing work on an older Somerville property, getting the footing depth right from the start is the single most important decision on the job.
If your project involves a full below-grade foundation rather than individual footings, our slab foundation building service covers full perimeter and slab foundation work for additions and new construction.
If you can see a gap opening up between your deck or porch and the main structure of your home, or if the deck surface has started to tilt noticeably, the footings underneath may have shifted or settled. In Somerville's winters, freeze-thaw cycles can push shallow footings upward year after year until the structure above them is no longer level or safe. This is worth having a contractor look at before the gap widens or the structure becomes a hazard.
When a footing settles unevenly, the structure above it shifts, and that shift often shows up first as doors or windows that suddenly do not open and close the way they used to. If you notice this in a part of your home that sits over or near an older addition, a porch, or a finished basement, it is worth asking a contractor whether the footings are the cause. In Somerville's older housing stock, this is a common early warning sign.
Cracks that spread diagonally from the corners of door frames or window openings often indicate that part of your foundation or the structure above it has moved relative to the rest. In a city like Somerville where many foundations are over 100 years old and were built without modern footings, this kind of movement is not unusual. A concrete contractor can assess whether the underlying footing situation is the cause and what it would take to stabilize it.
Any new structure attached to your home or standing in your yard needs proper footings before anything else is built. In Somerville, this work requires a permit, and the footing inspection happens before the concrete is poured, so this is not something you can skip or add after the fact. Getting the footings right at the start protects everything built on top of them for decades.
We install concrete footings for decks, porches, additions, stairs, and structural columns on Somerville residential properties. Every footing job includes permit application with Somerville Inspectional Services, utility locating through Massachusetts Dig Safe, the required pre-pour city inspection, and rebar placement sized to the load the footing will carry. We do not quote footing depth over the phone — the soil conditions, access constraints, and structural requirements on older Somerville lots vary enough that a site visit is the only honest way to scope the work.
For properties where footing work is the first step toward a larger project, our foundation raising service handles situations where an existing structure needs to be lifted and supported while new or reinforced footings are installed below it. This comes up regularly in Somerville's older housing stock, where original footings are inadequate for today's loads or have shifted enough to require replacement.
All work is permitted and inspected. A Somerville building inspector examines the footing depth, dimensions, and reinforcement before any concrete is poured. That inspection is your protection — it means someone independent verifies the most important structural work on your property while there is still time to catch a problem, before it is buried permanently.
Suits homeowners building or replacing a deck or porch — the most common footing project on Somerville residential properties.
Suits properties adding a room, sunroom, or structural addition that needs new perimeter footings tied to the existing foundation.
Suits exterior stairs that need frost-depth footings to stay level through Somerville winters without heaving or tilting.
Suits carports, pergolas, covered walkways, and freestanding structures that require individual post footings sized for the load.
The Massachusetts State Building Code sets the frost depth requirement at 48 inches for this region, but the code is only part of the picture. Somerville's soil is predominantly clay-heavy glacial material that drains slowly and holds moisture. Wet clay expands significantly when it freezes, creating pressure on anything in contact with it. A footing installed correctly in a well-drained sandy location may still perform poorly in Somerville's soil if the contractor does not account for this. The Massachusetts State Building Code sets the floor, and local soil conditions require going beyond it in some situations.
Most lots in Somerville are small and tightly bounded. Getting excavation equipment into a backyard often requires hand-digging in corners or working around fences, neighboring structures, and existing utilities. A contractor who has not worked in this environment before will underestimate the time and cost required. An experienced local crew factors this into the quote upfront, and it shows in how the job proceeds once the digging starts. The Dig Safe utility locate service is mandatory before any excavation in Massachusetts, and in older Somerville properties, it is especially important because private lines are common beneath yards that have been in use for over a century.
We work on footing projects throughout Somerville and the surrounding communities, including Cambridge, Medford, and Malden. The frost depth and soil conditions are consistent across all of these communities, and so is the permitting expectation.
We come to your property to look at the footing location, assess access conditions and soil, and understand the structure being built above it. You receive a written estimate within one business day of the visit. We do not quote footing depth or reinforcement requirements over the phone.
We apply for the required building permit through Somerville Inspectional Services. We also contact Dig Safe to have underground utilities marked before any digging begins. Both steps happen before the crew arrives on site, and both are included in what we handle for you.
The crew digs to the required depth, sets forms and rebar, and the city inspector visits to verify the work before any concrete is poured. This inspection is the checkpoint that protects you. Once the inspector approves, the concrete goes in the same day or the next, depending on scheduling.
After the pour, forms come off in one to two days. The footing needs about a week to reach working strength before framing can begin. We let you know when the concrete is ready, and the permit is closed out once the final inspection is complete.

(617) 634-5990Massachusetts requires footings to reach below the frost line in this region, which means close to four feet of digging on every residential job. We do not quote shallower depths to win on price. The cost of a shallow footing shows up in a shifted deck or cracked porch three winters from now, and fixing it then costs far more than doing it right the first time.
We apply for the Somerville building permit, coordinate the pre-pour city inspection, and close the permit out at the end. You do not have to follow up with any city office or worry about whether the work is on record. The finished footing is fully documented before we consider the job done.
We install footings in Somerville and 11 surrounding communities, including Cambridge, Medford, and Malden. That experience with varying lot conditions, soil types, and local permit offices means we handle the complications of older urban properties without surprises. The frost depth is the same across all of them, and so is our standard.
Somerville's housing stock is predominantly pre-1940. Our crews have worked in enough of these properties to know what to expect when the digging starts, from rubble foundations to private utility lines to fill soil where stable subgrade should be. We give you a straight answer when something unexpected turns up, not a panicked call and a ballooning invoice.
Footings are the part of your project you will never see again once the work is done. That is exactly why who does them and how they do it matters. We treat it as the most important step in the job, because structurally, it is.
