Cos Cob, the way it looks from a driveway

Cos Cob is a neighborhood of Greenwich, not a city of its own, and it grew up as a busy coastal village on the water, where a river runs out to Long Island Sound.

Around here and over in Riverside, older houses sit next to newer ones, often on lots that weren't laid out with a two-car driveway in mind. That mix means no two jobs start from the same ground, which is why I walk every property myself before I write anything down. Concrete is only as good as what it sits on, so on lots like these the base is most of the job.

The concrete work we do in Cos Cob

Driveways, patios and steps are what we're best known for, along with the rest of the flatwork, the concrete that lies on the ground like walks and pool decks. We also build walls, footings and foundations, and we raise or cut concrete that's already there. Every Cos Cob job starts with me on your property, measuring and looking at what the slab will sit on. We plan the dig, the base and the pitch from that, and the pretty part comes last.

  • Concrete driveway building

    A driveway that climbs from the street takes cars and runoff at once. We dig out, pack a stone base and pitch the slab so water heads to the street, not the garage.

  • Concrete patio construction

    A backyard patio ends up holding the grill, the table and every chair you own. We build the base for that weight, so the corner under the grill doesn't sink first.

  • Stamped concrete services

    Older houses often suit a patio or walk that looks like stone or brick, minus the loose pieces. We press the pattern into fresh concrete over the same packed base as any slab.

  • Concrete sidewalk building

    Front walks on older lots tend to heave and tilt where roots and settled dirt have pushed them. We pour new ones on a packed base, flat enough to roll a trash can down.

  • Garage floor concrete

    A cracked, chipping garage floor in an older house usually means a thin slab or a tired base. We break it out, fix what's underneath and pour a new floor that sweeps clean.

  • Decorative concrete

    Some houses here deserve more than plain gray around the entry or the pool. We add color, borders and finishes to new work, but the base still comes first, because pretty concrete cracks too.

  • Concrete retaining walls

    Sloped yards often need a wall to hold back dirt for a flat patio or a level driveway edge. We build them on proper footings with drainage behind, so water doesn't push the wall over.

  • Concrete floor installation

    Basements and sheds on older houses often need a new floor over dirt or a broken slab. We prep the subgrade, the ground the slab sits on, and pour it level.

  • Concrete pool decks

    A pool deck takes bare feet and splash water all summer. We give it a textured finish for grip and pitch it so water runs off instead of pooling at the edge.

  • Concrete steps construction

    Front steps on older houses settle, crack and pull away from the porch over time. We rebuild them on solid footings with every step the same height, so you're not guessing in the dark.

  • Slab foundation building

    Additions and garages on older houses need a slab that carries a building, not just feet. We pack the base and set rebar, the steel that holds the slab together, before we pour.

  • Foundation installation

    On a tight lot, a new addition starts with foundation walls the whole structure rests on. We set the forms, pour and check it's level and square before anything goes on top.

  • Concrete parking lot building

    Property managers with a small lot need concrete that takes daily traffic and sheds water. We grade it, pack a heavier base and pour so water heads to the drains.

    Explore service

  • Concrete footings

    Decks, porches, walls and additions all stand on footings, the concrete pads buried below them. We dig them to firm ground and pour them first, because a bad footing is hard to fix later.

    Explore service

  • Foundation raising

    A sinking corner or a slab that's dropped away from an older house usually points to settled dirt. We raise and support it, or tell you on site if replacing makes more sense.

  • Concrete cutting

    Adding a drain, widening a driveway or opening a doorway means cutting through concrete that's already there. We saw clean, straight lines, so the new work meets the old without a ragged edge.

What good concrete work looks like, start to finish

These photos show concrete work from the forms and packed stone to the finished surface. The early stages matter most, because the base is where good slabs and cracked ones part ways.

  • Concrete driveway with light gray slabs and red brick borders, beside a parked golf cart and landscaped yard.

  • Textured concrete pool deck surrounding a swimming pool, with patio steps and a covered seating area.

  • Curving concrete sidewalk beside a stone house, with a gravel bed, potted plant, and black metal bench.

Working in Cos Cob: permits, prices and pour dates

Cos Cob work runs through the Town of Greenwich, and that shapes the paperwork and the calendar. Here's what we check before the first shovel, and what moves your price once we're there.

Who makes the permit call in Cos Cob

Cos Cob doesn't run its own permits. Greenwich makes the call on your job, and it keeps a list of work that needs no building permit, which covers some flat concrete and short walls. Exempt work still has to meet the codes and Greenwich's other rules, so skipping the permit doesn't mean skipping the standards.

So the first question here is whether Greenwich wants a permit, and the answer sets the calendar. Before we set a date, we check with Greenwich's building office and tell you what it wants for your job. If a permit's needed, we handle the application with you, and the pour waits until it's sorted. If the office hasn't answered yet, you'll hear that from us too.

  • Tell us what the slab will hold, since a building can change things.
  • Ask any contractor who files the permit before you sign anything.
  • Keep your permit paperwork with the house papers once the job's done.

What moves your price and your dates

Price comes down to what's under the slab, not just the top. How much old concrete comes out, how far we dig to reach firm ground, how thick the slab has to be for what it carries, and whether a truck can reach the forms or we're wheeling it up a slope all move the number. Your written estimate shows what's in it.

Dates turn on a few things. The permit question comes first, if Greenwich wants one, and then the weather the week we pour, because we'd rather move a day than pour in midday heat and end up with a weak, dusty top. After the pour comes curing, the wait while the slab hardens enough to take weight, so plan on a stretch without the driveway or patio.

  • Curves and odd shapes take more forming than straight edges.
  • Steps, walls and rebar add labor and steel, so they add cost.
  • Ask us early if you need the driveway back by a set date.

What Cos Cob houses and lots ask of a slab

Cos Cob's houses and yards come in every age and shape, and the concrete has to fit the one it's on. These are the conditions I look for first when I walk a property here.

  • Yards that slope toward the house

    A lot of yards here tip one way or another, and plenty tip toward the house. Before we form anything, I check where the rain runs now, because a patio that falls toward your foundation just hands the water a shortcut. We set the base so the finished slab sheds it away.

  • Downspouts that empty onto concrete

    Plenty of downspouts empty right onto a walk or patio, so the slab takes a fire hose every storm and the dirt at its edge washes out. We look at where each one lands and plan the pitch so water leaves the concrete instead of tunneling under it.

  • Old concrete under new concrete

    On older properties it's common to find a newer slab poured right over an old one, or patches stacked over the years. New concrete over a cracked slab tends to pick up the same cracks. If yours has that, we break it out to the base and start clean.

  • Driveway ends that take a beating

    The end of a driveway, where it meets the street, takes turning tires, delivery trucks and whatever water runs down the driveway. It's usually the first part to crack and chip. We dig that section deeper and pack it harder, since that's where the weight lands.

  • Slabs that meet the house

    Patios, steps and garage slabs that butt against the house need a gap where they meet it, so the slab can move without cracking against the wall. Sealing that seam keeps water from running down beside your foundation. We set that gap on purpose instead of letting the concrete pick its own spot.

Why we build the base before we worry about looks

I spent years in landscaping before I learned concrete beside a crew and started this business in 2017. Both jobs taught me the same thing, that what's under a slab decides how long it looks good.

We spend the hour on prep, not polish

Here's the trade-off every concrete job has. The base, the dug-out and packed stone the slab sits on, is buried on day one, and it's the first thing a tight budget cuts. A fancy finish on a raked-level base looks great for a season, then settles with the dirt under it. Pretty concrete on a bad base is just an expensive crack with a nice finish.

So if something has to give, I'd cut the pattern or the color before I'd cut the prep. We dig out to firm ground, pack the stone in layers and check the pitch before any concrete shows up. I'd rather spend an extra hour on prep and tell you up front where a crack might show than explain it to you later.

  • I walk every job myself

    I come out to every job, look at the ground and the drainage, measure, and write the estimate myself. You're not getting a salesperson's guess. My crew does the work, and I'm on site for the parts that matter most, like the base check and the pour.

  • A written estimate you can check

    The estimate comes to you in writing and shows what's in it, from tear-out and base to thickness and finish. If you're comparing bids, that lets you see pretty quickly who quietly left the base out.

  • Joints cut where we choose

    Concrete cracks. That's not a sales line, it's chemistry. We cut control joints, shallow grooves that give the slab a planned place to crack, and we cut them on time, so a crack usually lands in a straight line we picked instead of across the middle of your patio.

  • Licensed, insured and guaranteed

    We're licensed and fully insured, and I'll show you the insurance before we start. Our promise is short, satisfaction guaranteed, and the prep, the joints and the timing of the pour are how we try to keep you from needing it. Call (475) 333-3026 and I'll come take a look.

Cos Cob concrete questions, answered plainly

These are the questions Cos Cob homeowners tend to ask before a concrete job, most of them about what Greenwich wants. Short answers first, then what it means for your project.

Do I need a permit for a concrete driveway or patio in Cos Cob, CT?

Greenwich's list of work exempt from a building permit includes driveways, sidewalks and on-grade concrete patios up to 30 inches above the ground beside them, as long as there's no basement or room underneath. A patio built up higher than that, or one sitting over a basement, isn't on the list. We don't take the list as the answer for your job until we've checked with the building office, and we'll tell you what it says.

Do I need a permit for a retaining wall in Cos Cob, CT?

Greenwich's exempt list covers retaining walls up to 3 feet, measured from the finished ground at the bottom to the finished ground at the top, unless the wall holds back extra load like a driveway or parked cars above it. A taller wall, or one carrying that kind of load, isn't on the list, so plan for the building office to weigh in. I'll measure yours when I walk the job, and we'll check with the office before we dig.

Who issues the zoning permit for a shed or garage slab in Cos Cob?

Greenwich's Zoning Enforcement Office issues zoning permits for any accessory building over 6 feet tall, like a detached garage or a shed you can stand up in, whatever its floor area. One-story sheds and playhouses up to 200 square feet are on Greenwich's list of work that needs no building permit, but that list is about the building permit, not zoning. Tell us what's going on the slab when you call, and we'll check what Greenwich wants before we pour.

How much does a concrete driveway cost in Cos Cob, CT?

I can't give you an honest number until I've walked your driveway, and then you get it in a written estimate that shows what's in it. The choice that lowers it most is a broom finish, the light brushed texture that gives tires and shoes some grip, over stamping or color. The one place I won't help you save is the base, because that's the part you pay for twice if it's done cheap.

How long does it take before I can drive on a new concrete driveway?

You can usually walk on a new slab well before you can drive on it, because the concrete keeps curing after the top looks dry. Driving on it early is how you end up with tire marks and cracks you paid for. I'll give you both dates for your job before we pour, and we'll leave it blocked off until it's ready.

How do I file a building permit for a concrete job in Greenwich, CT?

In person, because Greenwich takes building permits by email only for re-roofing, re-siding and replacement windows on one- and two-family houses. Papers for an application that's already pending, or for meeting permit conditions before a certificate of occupancy, can go by email to bldginsp@greenwichct.org. If your job needs a permit, we handle the application with you.
