A cracked, heaved, or uneven floor makes a basement unusable and a garage hard to keep clean. We install reinforced concrete floors with the subbase prep, control joints, and sealing that keep them flat and durable through Boston winters.

Concrete floor installation in Somerville means removing the old surface if needed, compacting the subbase, placing reinforcement, pouring and finishing the slab, and cutting control joints to manage cracking — most basement or garage floors are poured in a single day, with a 24 to 48-hour wait before foot traffic and a full week before heavy use.
Most homeowners contact us after noticing sections of their basement floor heaving or cracking, water pooling in low spots after rain, or a surface that has been flaking and degrading for years. Somerville averages more than 100 freeze-thaw cycles per year, and the city's older housing stock means many basement floors were poured decades ago with minimal reinforcement on top of unstable fill. A properly installed new floor fixes all of that, and gives you a clean base for whatever you want to do with the space next.
If the space is a garage rather than a basement, our garage floor concrete service is purpose-built for vehicle traffic, road salt exposure, and the moisture conditions specific to enclosed garage spaces.
Sections of basement floor that have lifted, dropped, or developed cracks wide enough to catch a coin have been damaged by ground movement or moisture. In Somerville's older homes, this is extremely common — many basement floors were poured decades ago with minimal reinforcement and are simply worn out. A floor that flexes or sounds hollow underfoot is telling you the base underneath has failed.
Puddles forming in low spots after heavy rain or when snow melts off boots signal that the floor has settled unevenly and is no longer draining properly. Somerville's clay-heavy soil means floors in older basements shift over time. Standing water leads to mold, damaged belongings, and a floor that keeps getting worse season by season.
When the top layer of a concrete floor starts to chip off or develops a rough, pitted texture across a large area, the surface has deteriorated past simple patching. Road salt tracked in from Somerville's heavily salted winter streets accelerates this process on unsealed concrete. Once the surface is compromised broadly, a full replacement is the cost-effective path forward.
If you are turning an unfinished basement into living space — a home office, playroom, or rental unit — you need a level, smooth, properly sealed floor before any other work goes in. Many Somerville homeowners are doing exactly this as housing costs push people to maximize every square foot. A new concrete floor is the right first step before any framing, flooring, or finish work begins.
We install concrete floors for basements, utility rooms, unfinished spaces, and interior slabs throughout Somerville. Every pour includes subbase assessment and compaction, steel mesh or rebar reinforcement, control joints cut to guide any future cracking into straight predictable lines, and sealing after the curing period. We pull permits through Somerville's Inspectional Services Department for any project that requires one, handling the application so you never need to visit a city office.
Finishing options are worth discussing before the pour, not after. A smooth troweled finish suits a basement being converted to living space. A broom-dragged texture provides grip in utility or storage areas. Stained or polished finishes can make a basement floor genuinely attractive at a fraction of the cost of adding them after the fact. Our concrete pool decks service uses the same decorative finishing techniques for outdoor applications, and the two projects can share a mobilization visit when timing allows.
For homes being renovated from the ground up, floor installation often follows structural foundation work. Our garage floor concrete service handles the specific mix, finish, and thickness requirements that make a garage slab perform differently from a basement slab.
Suits homeowners replacing a failed slab or pouring a new floor in an unfinished basement before finishing the space.
Suits utility and storage areas where a clean, functional surface is the goal without decorative cost.
Suits homeowners finishing a basement into living space who want an attractive, low-maintenance floor surface.
Suits properties with an existing failed slab where demo, debris removal, and a full new pour are all part of the same project.
Somerville averages more than 100 freeze-thaw cycles per year. That constant ground movement puts stress on any slab sitting on top of it, and a floor installed without proper subbase compaction and reinforcement will show it within a few years. The vast majority of Somerville's housing stock was built before 1950, and a large share dates to the late 1800s. Older homes frequently have basement floors poured on rubble fill or soil that has settled unevenly over a century of use. Before any new concrete goes in, we assess what is underneath — and in Somerville, that assessment almost always turns up something that needs addressing first.
Logistics are their own challenge here. Getting a concrete truck close enough for an efficient pour on a Somerville street can require a pump truck, special scheduling around parking restrictions, or coordination with neighbors. We encounter these conditions regularly when working throughout Somerville, and in nearby Cambridge and Brockton, where older housing stock and dense streets present similar conditions.
Road salt is another factor specific to this area. Salt tracked in from Somerville's heavily treated winter streets eats into unsealed concrete over time, accelerating surface deterioration from the top down. We recommend sealing every new floor approximately 30 days after installation and following the American Society of Concrete Contractors guidelines for resealing intervals based on your traffic level — guidance we pass along with every completed job.
Call or submit a form and we respond within 1 business day to schedule a free on-site visit. Floor condition, space size, access for a concrete truck, and any old material to be removed all affect your price — we need to see the space before quoting it accurately.
We examine the existing floor or ground, check for moisture issues, assess the subbase condition, and figure out the most practical way to get materials into the space. In Somerville, this step always includes looking at truck access and street logistics. A permit is applied for at this stage, before any work is scheduled.
Clear the space completely before the crew arrives. If an old floor is being removed, we handle that and debris disposal — confirm whether removal is included in your quote. The pour itself takes most of a full workday for a typical basement or garage. You do not need to be on-site the entire time, but someone should be available at the start.
Light foot traffic is safe after 24 to 48 hours, but keep heavy items off the floor for at least a week. We return to apply sealer once the curing period is complete and walk the finished floor with you, pointing out the control joints and explaining how to maintain the surface. Care instructions are provided in writing.

(617) 634-5990In Somerville's pre-1950 housing stock, what is under the floor matters as much as the pour itself. We probe and assess the base before any concrete goes in, so unstable soil, old fill, or drainage issues are addressed first — not discovered after the new floor cracks in year two.
We manage the permit application through the City of Somerville Inspectional Services Department from start to final inspection. You do not fill out forms or make follow-up calls. The permit is on record before any demolition begins, protecting your investment when you sell.
Control joints guide any future cracking to happen in straight, predictable lines rather than randomly across the surface. This is standard practice we include on every job — not an upsell. It is one of the most visible signs of a contractor who knows what they are doing.
Somerville's winters are hard on any concrete that was not installed with local conditions in mind. The mix design, base prep, and reinforcement we use are selected for this climate specifically. The National Ready Mixed Concrete Association's cold-weather guidance informs how we approach every pour from October through April.
Taken together, these practices mean a floor that stays flat, resists cracking, and holds up to the road salt and temperature swings that come with living in Somerville. Homeowners in Cambridge and Brockton who face the same conditions get the same approach from us on every job.
