Shallow footings fail in Concord winters. We dig to the depth New Hampshire requires, pull the permit, pass the inspection, and pour - so your deck or addition stays level for decades.
Concrete footings in Concord are the buried bases that hold up decks, home additions, and garages - dug to at least 48 inches below grade to stay below the frost line, formed and poured with anchor hardware, then inspected by the City of Concord before concrete goes in, with most residential projects completed in one to two days of active work followed by a seven-day curing period before framing can begin.
Footings are the part of your project you never see once the work is done - but they determine whether your deck stays level or starts tilting within a few seasons. Concord's ground freezes to roughly four feet every winter, and a footing poured above that depth will eventually be pushed upward by frost movement. This is a common cause of deck problems in older Concord neighborhoods where original footings did not meet current depth standards. When a project also requires a full foundation or a concrete slab, we coordinate footings with our foundation installation service so the structural base is built as one system.
Concord's construction season runs from roughly late April through October. Contractor schedules fill quickly in May and June. If you are planning a deck or addition for summer, reaching out in March or April gives you the best chance of getting your project on the calendar.
If your deck has developed a noticeable tilt, or if the boards no longer sit level, the footings underneath may have shifted. In Concord, this often happens when footings were poured too shallow and frost movement has pushed them out of position over the years. A shifting deck is not just cosmetic - it can become unsafe.
Diagonal cracks running from corners of windows or doors, or stair-step cracks in a block foundation, can signal that footings below are settling unevenly. Concord's mix of older homes and variable soil conditions makes this a relatively common issue in established neighborhoods. New cracks, or cracks that appear to be growing, are worth having a contractor look at.
Any new structure attached to or near your home needs proper footings before framing can begin. In Concord, where the frost depth is 48 inches and the construction season is short, getting footings quoted and permitted early is the right first step. Contractors fill up fast once the ground thaws in spring.
When steps or a porch slab start to separate from the main structure, it usually means the footing beneath them has moved. This is a common sign in Concord homes that have gone through many freeze-thaw cycles, particularly in properties built before modern frost-depth requirements were standard.
We pour footings for decks, home additions, garages, and supplemental structural work on older Concord homes throughout the city and surrounding communities. Every project starts with an in-person site visit - we check the soil, assess whether ledge is a possibility, and measure the area before giving you a number. For projects that involve both footings and a full foundation wall system, we coordinate the two scopes so nothing has to be ripped out and redone. We also work directly with our foundation raising team when a home needs both new footings and lift work on an existing foundation.
We handle the entire permit and inspection process through the City of Concord's Building Division - from the initial application through the pre-pour inspection. We also call 811 before any digging begins to have underground utilities marked, which is required by law in New Hampshire. When a project needs both footings and a full foundation installation, we schedule the work so each phase can be inspected and approved without holding up the next.
Required for any new deck build in Concord - drilled or hand-dug to the 48-inch frost depth and poured with anchor hardware for post bases.
Suited to homeowners adding a room, sunroom, or attached garage, where new footings must connect structurally to the existing foundation.
For detached garages where a full footing perimeter is required before slab or stem wall construction can begin.
For Concord homes built before modern frost-depth standards, where existing footings may not support the load of a planned addition.
New Hampshire's frost depth requirement is 48 inches - four feet below the surface. That is significantly deeper than in most other states, and it makes footing work here more labor-intensive and more expensive than national cost guides suggest. Concord also sits on glacial till that includes granite bedrock in many neighborhoods. When a crew hits ledge before reaching the required depth, they may need heavy equipment to break through - and that adds real cost and time. A contractor who quotes you without looking at your specific site is either guessing or planning to underbid and absorb the ledge cost later. The New Hampshire State Fire Marshal's Office administers the building code that sets these requirements - see nhfiresafety.org for code reference.
We serve Concord and the surrounding area, including homeowners in Franklin and Laconia. Whether your home is in one of Concord's older downtown neighborhoods - where pre-1960 footings are common - or in a newer subdivision on the west side, the frost depth requirement and permit process apply equally. We have worked on both.
When you reach out, we ask a few basic questions - what you are building, where on your property, and whether you have had any drainage or soil issues. You do not need all the answers; this conversation just gets the process started. We reply within one business day.
We visit your property to check the ground conditions, measure the area, and assess whether anything - like ledge rock or a slope - could affect the work. After the visit you receive a written estimate that explains what is included and what could change the price. We never quote footing work over the phone on a site we have not seen.
Before any digging starts, we apply for the required building permit through the City of Concord's Building Division. Permit processing typically takes a few days to a couple of weeks. We call 811 before digging to have underground utilities marked - required by law and something we handle automatically.
The crew digs to the required four-foot depth, sets forms, and waits for the city inspector to approve depth and layout before concrete goes in. After the pour, footings cure for at least seven days before framing begins. We let you know exactly when it is safe to move forward with the next phase of your project.

(603) 802-8228New Hampshire's frost depth requirement is non-negotiable, and we build it into every estimate without exception. Footings poured too shallow fail - usually quietly, over one or two winters, before the damage shows up in the structure above.
Ledge rock is a real possibility in Concord and Merrimack County. We ask about soil conditions before we quote, flag ledge risk based on your neighborhood, and write our estimates to reflect what we actually expect to find - not the best-case scenario.
We apply for the City of Concord building permit, coordinate the pre-pour inspection, and make sure the work is approved before concrete goes in. Your project is on record, your property value is protected, and you never have to navigate the building department on your own. Concord Building Division.
A significant share of Concord homes were built before 1960. We assess existing footings before quoting addition work on older properties, so you know upfront whether supplemental footings are needed. We follow American Concrete Institute standards for footing design - see concrete.org.
Every footing project we take on in Concord is backed by an in-person site assessment, a written estimate that accounts for local soil conditions, and a permit-and-inspection process handled entirely on your behalf. You get a foundation that works - not one you have to revisit in two winters.
