Smithtown Concrete Contractor Pros
631-791-6519Free Smithtown quotes for driveways, aprons, walls and patios.
Driveways, Belgian block aprons, patios, retaining walls, pool decks, steps and slabs across Smithtown and western Suffolk County. Poured on a compacted base, jointed to a published spec, and mixed to survive the roughly 98 nights a year this end of Long Island spends at or below freezing.
Concrete on Long Island rarely fails because somebody mixed it wrong. It fails because water got into it and then froze. The NOAA 1991-2020 normals for the Islip station, the closest long-run climate record to Smithtown, show about 98 nights a year at or below 32 degrees and 45.99 inches of precipitation, with December the wettest month at 4.71 inches. That is the whole problem in two numbers: a slab that stays wet, and 98 separate chances a year for the water inside it to expand. Everything we do is built around keeping water out of the concrete and giving the concrete somewhere to move when it wants to.
Smithtown Concrete Contractor Pros forms and pours flatwork across Smithtown and the rest of western Suffolk County - driveways, patios, walkways, steps and stoops, slabs and footings, plus repair and resurfacing on concrete that is still worth saving - and the masonry that goes with it: Belgian block aprons and curbing, driveway aprons and sidewalks in the Town right-of-way, retaining walls, pool decks, brick steps and block walls, and lifting settled slabs that do not need replacing. The Town of Smithtown covers 53.75 square miles of land and is close to fully built out, so most of the work here is replacement: 1950s and 1960s subdivisions with cracked aprons, heaved walkways and stoops that have dropped an inch off the sill. We quote in writing, we pull the permits the Town actually requires, and we will tell you when a slab does not need replacing yet.

Tear-out, base preparation, forming and a poured concrete driveway sized for what actually parks on it - four inches of slab for cars, five or six where a truck or an RV sits. The apron at the street is a separate job with its own Town of Smithtown permit, and we handle that end too. Broom finish standard, decorative finishes priced separately.
Typical: $12 - $20 per sq ft broom finish; roughly $6,000 - $14,000 for a 500 to 700 sq ft two-car driveway
Granite Belgian block set in concrete as a driveway curb, a border band, or a full apron at the street. Edging is priced by the foot and aprons by the square foot, and the right-of-way permit and any village curb approval come before the stone is ordered.
Typical: $9 - $11 per ft of edging; $18 - $50 per sq ft for cobblestone paving (national)
Replacement of the driveway apron and the concrete sidewalk in front of the house, built to the Town of Smithtown street spec of four-inch walks and six inches where the walk crosses the drive, under a right-of-way permit from whoever owns the road at the curb.
Typical: $8 - $18 per sq ft for a concrete apron; $7 - $17 per sq ft for sidewalk (national)
Poured patios, front walks, side paths and pool surrounds, pitched to move water away from the house and isolated from the foundation so the slab can move without dragging on it. Broom, sand-swirl and exposed-aggregate finishes. Smithtown caps paving in required yards at 25 percent, so the layout gets checked before the forms go in.
Typical: Patios $14 - $16 per sq ft broom finish, $18 - $25 stamped; walkways roughly $14 - $22 per sq ft installed
Stamped, integrally colored and exposed-aggregate concrete for patios, walkways, pool decks and entries. Same structural slab underneath, different surface treatment on top. Pattern and joint layout get planned together so the control joints land where the pattern hides them instead of running through the middle of a stone.
Typical: $18 - $25 per sq ft stamped; $20 - $30 per sq ft for exposed aggregate and multi-color work
New concrete pool decks and resurfacing of worn ones: a slab isolated from the pool's bond beam, pitched away from the water, finished to resist slipping and kept light in color to stay cooler underfoot, with the pool barrier and permit questions settled before the pour.
Typical: $4 - $15 per sq ft poured; $8 - $30 stamped; $3 - $12 to resurface
Front stoops, side entries, basement hatchway steps and landings, formed and poured on footings rather than set on grade. Riser and tread geometry built to the Residential Code of New York State, with handrail anchors set at the pour on any flight of four or more risers.
Typical: $1,500 - $6,000 for a poured stoop on new footings; simple steps built into a new patio from $500 - $2,500
Brick and bluestone front steps on a poured core, CMU garden and foundation walls, brick and stone veneer, and repointing. The page covers Grade SW brick, Type N and S mortar, caps and copings with drips, riser and handrail rules, Town wall heights and published national prices.
Typical: $600 - $900 per brick step; $15 - $30 per sq ft of CMU wall (national)
Poured concrete and mortarless segmental block walls for the slopes, banks and grade changes around the Town of Smithtown, built on a footing or leveling pad with drainage stone and a perforated pipe behind them, and permitted where the wall tops 30 inches.
Typical: $15 - $45 per sq ft of wall face; poured $20 - $45, block $20 - $35
Shed and detached garage slabs, hot tub and generator pads, air conditioning and pool equipment pads, footings, and grade beams. Sized and reinforced for the load that is actually going on them, poured on compacted base, and jointed so shrinkage cracks land on a line you chose.
Typical: $1,200 - $4,500 for a typical shed, hot tub or generator pad; larger slabs quoted at $12 - $18 per sq ft
Crack repair, joint sealing, spall and edge rebuilding, single panel replacement, and polymer-modified cement overlays on slabs that are still structurally sound. Salt scaling and settled panels are two different problems with two different fixes, and we will tell you which one you have before quoting.
Typical: $4 - $9 per sq ft for a polymer-modified overlay; crack and joint repair typically $6 - $14 per linear ft
Sunken walks, driveway panels, patios, stoops, garage floors and pool decks raised back to grade with polyurethane foam or cement-grout mudjacking, with the void underneath filled so the slab stops dropping. The page covers why slabs sink in Smithtown's sandy ground, what each method weighs and costs, and when replacement is the better call.
Typical: $4 - $9 per sq ft mudjacking; $8 - $25 per sq ft polyurethane foam (national)
Concrete exposed to deicing chemicals falls under exposure class F3, which calls for a minimum of 4,500 psi, a maximum water to cementitious ratio of 0.45, and a target air content of 6.0 percent for the aggregate used in flatwork here. That is what gets ordered on the ticket, and it is why a surface holds up through winters of road salt rather than flaking in year three.
Concrete cracks. The only real choice is whether it cracks along a line you picked or somewhere you did not. Industry guidance puts control joint spacing at 24 to 36 times the slab thickness with a practical maximum of 15 feet, joints cut at least a quarter of the slab depth, and panels kept close to square with length no more than 1.5 times width. We lay that grid out on the estimate.
Work in the Smithtown right-of-way needs an excavation permit under Section 245-15, and the fee schedule at Section 245-18A(2) lists a residential driveway apron at $150. West of the town line in Commack, Huntington's Chapter 173 governs instead. Knowing which office issues the permit for your address is not a detail worth improvising on the day of the pour.
The estimate lists thickness, base preparation, square footage, reinforcement, joint layout, finish and the cure schedule as separate lines, so you can see where the money goes and compare quotes on the same terms. If a competing bid is cheaper, the difference is almost always in one of those lines, and it is usually the base.
We measure the area, shoot the grade to see where water goes today, look at what is under the existing slab where we can, and hand back an itemized written estimate with thickness, base, reinforcement, joint spacing and finish spelled out.
Any right-of-way or apron work gets filed with the Town before scheduling, and underground utilities get marked out. This step is where a job either starts on time or does not, so it happens before a date is promised.
Existing material comes out, organic soil and old fill get removed rather than compacted, the subgrade is brought to grade and compacted in lifts, forms are set to the finished elevations and pitch, and reinforcement is positioned and supported off the base.
Concrete is placed, screeded, floated and finished, joints are cut within the working window at the planned spacing, and the slab is cured. You get written dates for foot traffic and for vehicles before anyone leaves the site.
Smithtown covers 53.75 square miles of land between Long Island Sound on the north, Islip to the south, Brookhaven to the east and Huntington to the west, and the ground is not the same across all of it. Long Island's surficial geology is dominated by two glacial moraines with outwash sand and gravel between and south of them, and the north shore end of the Town sits on that moraine ground while the flatter interior sits on outwash. The practical difference shows up in the hole. Outwash subgrade is stratified sand and gravel, drains freely, and compacts into an excellent bearing surface. Moraine ground carries till, silt lenses and boulders that hold water and behave far less predictably, which changes how much material comes out before anything goes back in.
The dominant soil across the outwash sections of Suffolk County is the Riverhead series, which the USDA describes as very deep and well drained, formed in glacial outwash derived largely from granitic material, with high saturated hydraulic conductivity in the solum and very high in the substratum. For a concrete contractor that is mostly good news - a properly compacted native subgrade here is better than the imported base a lot of jobs in heavier soil require. The catch is that free-draining ground erodes when concentrated water is put on it. A downspout dumping at the edge of a slab on sand will undermine that slab far faster than the same downspout would on clay, which is why the drainage detail matters as much here as the concrete does.
The housing stock is what drives the work. Smithtown's own comprehensive plan update describes the Town as almost fully developed and notes that most of it was built after 1950, and the census figures back up what that means today: 116,296 residents at the 2020 count, an owner-occupied rate of 88.7 percent, and a median owner-occupied home value of $669,900. That is a town of long-held single-family houses whose original flatwork is now sixty and seventy years old. Cracked aprons at the curb, walkways that have lifted a quarter inch at a joint, stoops that have dropped below the door sill, and driveways poured before anyone specified air entrainment - that is the everyday inventory across Nesconset, St. James, Kings Park, Commack and the Smithtown hamlet itself.
Concrete pricing on Long Island runs higher than the national figures you will find online, and it is worth knowing why before comparing quotes. Material, disposal, labor and permitting all cost more in Suffolk County, and tear-out of an existing surface is a real line item rather than a rounding error. Current Long Island market ranges put a standard broom-finished concrete driveway at roughly $12 to $20 per square foot and decorative finishes at $18 to $30. A well-built concrete driveway here has a service life in the range of 30 to 40 years, which is the number that makes the arithmetic work. Here is how the individual line items generally fall.
| Service | Typical Smithtown Range |
|---|---|
| Concrete driveway, broom finish (500 - 700 sq ft, two cars) | $6,000 - $14,000 |
| Concrete driveway, per square foot (4 in slab, standard finish) | $12 - $20 per sq ft |
| Stamped, colored or exposed-aggregate concrete | $18 - $30 per sq ft |
| Concrete patio, broom to stamped finish (300 - 400 sq ft) | $4,200 - $10,000 |
Current Long Island ranges put a standard broom-finished concrete driveway at roughly $12 to $20 per square foot, which works out to about $6,000 to $14,000 for a typical 500 to 700 square foot two-car drive. Decorative finishes run $18 to $30 per square foot. Tear-out of the existing surface adds $1,500 to $4,000, and an apron at the street with its Town permit adds $1,500 to $3,500 on top of that.
Roughly 30 to 40 years when it is built on a properly compacted base with an air-entrained mix and correctly spaced joints, and materially less when any of those three are skipped. The limiting factor here is not traffic, it is the combination of deicing salt and about 98 nights a year at or below freezing. Sealing every few years and using sand or a non-chloride deicer rather than rock salt is what buys the top of that range.
For work in the Town right-of-way, yes. Section 245-15 of the Town of Smithtown Code requires an excavation permit for work in a Town street, and the fee schedule at Section 245-18A(2) lists a residential driveway apron at $150. Retaining walls require a separate permit under Section 112-26. For patios, walkways and slabs on private property, the Building Department is the authority and the answer depends on the specifics, so we ask them rather than guess.
Section 322-12I(8) of the Town zoning code states that not more than 25 percent of the required front, side or rear yards shall be paved surfaces for residential uses, with driveways excepted and the front yard allowance increased as necessary to accommodate a twelve-foot swath for a circular driveway. On smaller lots that limit can be reached sooner than expected once an existing walkway, patio and shed pad are counted, so we check it at layout.
Late spring through fall gives the most reliable conditions. Concrete gains strength as a function of temperature and time, so cold weather slows the schedule and requires protection, while very hot, dry, windy days accelerate surface set and increase plastic shrinkage risk. April through early November is the comfortable window here. Winter pours are possible with blankets, heated mixes and longer cure schedules, and they cost more for that reason.
Foot traffic after about seven days, vehicles after 28 days. Concrete is specified at 28-day strength, and the first week is when the surface is most easily damaged. Those windows lengthen in cool weather because strength gain slows with temperature. We barricade the apron and give you written dates at the end of the pour so the schedule does not get decided by a delivery truck backing into the driveway on day four.
Concrete shrinks as it cures and it cannot shrink without cracking somewhere, so control joints are cut to decide where. Guidance for slabs on grade puts joint spacing at 24 to 36 times the slab thickness with a practical maximum of 15 feet, joint depth at a quarter of the slab thickness or more, and panels kept close to square. Cracks that follow those joints are the system working. Cracks that ignore them mean the ground underneath is moving.
Not in the first winter, and preferably not after that either. Deicing salt increases how much water the concrete absorbs and holds, and each freeze expands that water inside the surface paste until it flakes away. That is the scaling you see in the wheel tracks of older driveways. Sand for traction costs almost nothing and does no damage, and calcium magnesium acetate is the gentlest of the chemical deicers on concrete.
Concrete costs more up front and lasts substantially longer, typically 30 to 40 years against roughly half that for asphalt, and it does not need resealing on a two to three year cycle. Asphalt is cheaper initially, more forgiving of minor ground movement, and easier to patch invisibly. On the well-drained sand and gravel subgrade common through this Town, concrete is usually the better long-run value if you plan to stay in the house.
