A footing too shallow for Vermont's frost depth will move, tilt, and crack whatever sits on top of it. We pour concrete footings below the freeze line so your deck, porch, or addition stays exactly where you built it.
Concrete footings in Burlington, VT are poured underground anchors that support decks, porches, additions, and structural columns - the crew digs to at least 48 inches below grade to clear Vermont's frost line, sets forms, pours the concrete, and coordinates a city inspection before any structure is built on top, with most residential jobs completed in one to two days of visible work.
Burlington sits in the Champlain Valley, and its soils range from well-drained sandy loam near the lake to heavier, wetter clay-based ground in lower-lying neighborhoods. Clay holds moisture and moves more with freeze-thaw cycles, which means a footing that performs well in one part of Burlington might need a different design two streets over. The city also requires building permits and a pre-pour inspection for most footing work, so a contractor who knows the local permit process is not a nice-to-have - it is how the job gets done correctly.
If your project involves building a full foundation rather than individual post footings, our foundation installation service covers continuous poured foundations for additions and new construction with the same frost-rated approach.
If you can see a gap opening up between your porch and the main house, or if your deck surface tilts noticeably in one direction, the footings below may have shifted or failed. In Burlington, this often happens after a harsh winter when freeze-thaw cycles have pushed a shallow or undersized footing out of position. A leaning structure puts stress on every connection point above it.
Horizontal or stair-step cracks near the bottom of a foundation wall, or cracking where a post meets its base, can signal that the footing underneath is moving or deteriorating. These are not always cosmetic - they can mean the footing is no longer holding the structure steady. New cracks that were not there last year are worth getting a contractor's eyes on.
Any new structure attached to or built near your home needs proper footings before anything else goes up. Footing work is the first conversation to have - not an afterthought. Getting the footings right from the start is far cheaper than fixing a settling structure two or three years later.
Burlington has a large inventory of homes built in the early-to-mid 20th century, many with original footings not designed to last indefinitely. If you are doing any renovation that touches the structure - finishing a basement, adding a load-bearing wall, or replacing a porch - a contractor should look at what is supporting things below grade before you build on top of a hidden problem.
We pour concrete footings for decks, porches, additions, outbuildings, and accessory structures throughout Burlington and the surrounding area. Every project starts with a free on-site assessment of the dig depth needed, soil conditions, and access for equipment. We handle the permit application with the City of Burlington and coordinate the pre-pour inspection - you should not have to chase that down yourself. When your project also involves leveling or rebuilding an existing foundation, our foundation raising service handles the lifting and releveling work alongside any new footing pours.
Before any digging starts, we call Vermont 811 to have underground utilities located and marked - required by Vermont law, and a step that protects your property and the crew. If we are working on an older Burlington home and find that existing footings need to be assessed or replaced before new work begins, we flag that during the estimate rather than mid-project. We also take cold-weather conditions seriously: in Burlington's shoulder seasons, the crew protects fresh poured concrete from overnight freezes to ensure it cures to full strength.
Individual post footings dug below the 48-inch frost line - the right foundation for any deck or porch project in Vermont.
Continuous or spread footings for room additions, load-bearing walls, and attached structures built to city permit requirements.
Evaluation of existing footings on older Burlington homes, with replacement recommended only when the existing work genuinely cannot support the structure above.
Burlington has a large inventory of homes built before 1940, and many of them were built with footings that were never designed to last indefinitely. The Hill Section, the Old North End, and the South End all have properties where the original porch footings, garage footings, or outbuilding foundations are original construction - and decades of Vermont freeze-thaw cycles have taken a toll. Vermont's frost line of roughly 48 inches is among the deepest in the continental United States, according to depth references maintained by the Vermont Agency of Transportation. Any footing installed above that depth will move. The American Concrete Institute provides the professional standards for structural concrete work that guide how this depth and mix design should be handled in freeze-thaw climates like ours.
We serve homeowners throughout the Burlington area. If your property is in Williston or Essex Junction, the same frost depth requirements and soil assessment approach apply - and so does the same permit-first process before any digging begins.
We ask some basic questions about what you are building or repairing, then schedule a free site visit. We look at the dig depth needed, soil conditions, and access to the site before quoting anything. Most written estimates are delivered within one business day of the visit.
We submit the permit application to the City of Burlington on your behalf and coordinate the pre-pour inspection. Before any digging starts, we call Vermont 811 (Dig Safe) to have underground utilities marked - required by state law and usually completed within a few business days.
The crew digs to at least 48 inches below grade - Burlington's frost depth - then sets up temporary forms that shape the concrete. This is the noisiest part of the project. Depending on the size of the job, excavation and forming typically take one day.
A city inspector confirms depth and dimensions before the concrete goes in. After the pour, the contractor may cover the fresh concrete to protect it from Burlington's cool nights during curing. Forms come off after a few days to a week, and we walk you through what to expect before the next phase of your project can begin.
Free on-site estimate. Permits handled. No surprises when we hit what is underground.
(802) 307-0462Vermont's frost line sits at roughly 48 inches below grade in the Burlington area, among the deepest in the continental United States. We dig every footing to that depth or beyond - not because it is required on paper, but because anything shallower will shift when the ground freezes and thaws each winter. That is the only detail that determines whether your structure stays level for decades or starts moving within a few years.
Burlington's soils range from well-drained sandy loam near the lake to heavier clay-based ground in lower-lying neighborhoods. Clay holds moisture and shifts more with freeze-thaw cycles, which affects how a footing performs over time. We assess what is underfoot at your specific site before finalizing the design - this is not a one-size-fits-all situation, and the right approach depends on what your crew actually finds.
Most footing work in Burlington requires a city building permit and a pre-pour inspection. We handle the application, coordinate with the inspector, and keep you updated so you are never chasing down approvals. Unpermitted structural work can create problems when you sell or make an insurance claim - our work is always permitted and on record.
Burlington has a large stock of homes built before 1960, and many have original footings that have never been evaluated. If your project involves building on or near existing footings, we assess what is already there first - not after we have started digging. The American Concrete Institute sets the standards we follow for evaluating and pouring structural concrete.
Footing depth, soil assessment, permit coordination, and cold-weather curing - each of these details matters because Burlington's winters test every structural decision you make underground. We build to what this climate actually demands, and we have the local experience in Chittenden County to know what that means in practice.
