Concrete work in Portsmouth, NH

Portsmouth Concrete Works is a concrete contractor in Portsmouth, NH, covering 16 kinds of work, from flatwork like driveways, patios and walks to foundations, footings and cutting. Most calls start with cracks, sinking, chipping or water pooling by the house, and the fix usually starts below the surface. The price moves with the size and thickness of the slab, how much base work the ground needs, whether old concrete comes out first, how easy the spot is to reach and the finish you pick. The schedule turns on permit questions, the season and the cure time before you can use it. Your free estimate spells out the base, the mix and how we'll protect the fresh concrete, so you can compare bids line by line.

  • A broad light-gray concrete driveway with control joints leads to two garage doors, bordered by lawn and shrubs.

    Concrete driveway building

    We dig out the soft dirt, pack a solid base and pour a new driveway that sheds water away from the house and holds up to daily parking.

  • A stone outdoor patio features a circular fire pit, black chairs, and a curved wall with several small water features.

    Concrete patio construction

    Want a solid spot for a grill and a table out back? We build concrete patios sized to how you'll use them, pitched so rain runs off.

  • A circular stamped-concrete walkway surrounds a grass island, with a straight path leading toward the house steps.

    Stamped concrete services

    Stamped concrete is pressed with patterns while it's still soft, so a patio or walk can look like stone or brick for homeowners who want more than gray.

  • A stamped concrete walkway curves through mulched landscaping toward a porch with red chairs and a bright red door.

    Concrete sidewalk building

    We pour front walks and side paths with a broom finish, brushed while the concrete is still soft so your shoes grip when it's wet.

  • Aerial view of a large industrial warehouse with surrounding concrete parking areas, sidewalks, and driveways.

    Garage floor concrete

    Cracked, sunken or chipping garage floor? We tear out the old slab, rebuild the base and pour a new floor that drains toward the door.

  • A broad tan stamped-concrete driveway with an irregular stone pattern leads to a two-car garage beside flower planters.

    Decorative concrete

    Decorative concrete covers color, exposed stone and custom edges for homeowners and businesses who want a slab that fits the look of the property.

  • Tiered concrete retaining walls with irregular stone-pattern faces support landscaped beds and steps beside a house.

    Concrete retaining walls

    Is your sloped yard washing out or leaning? A concrete retaining wall holds the soil back, with drainage behind it so water doesn't push it over.

  • Decorative concrete patio with multicolored exposed stone aggregate beside a pale stone house and timber pergola.

    Concrete floor installation

    We pour interior concrete floors for basements, shops and commercial spaces, finished smooth and level so they're ready for use or flooring on top.

  • Concrete patio with outdoor dining and lounge seating in front of a covered white house, surrounded by autumn trees.

    Concrete pool decks

    A concrete pool deck needs to drain fast and stay safe under bare feet, so we slope it away from the water and pick a finish with grip.

  • Concrete steps rise between curved block retaining walls to a fenced residential patio.

    Concrete steps construction

    Front steps crumbling or uneven? We form and pour new concrete steps with even rises so nobody catches a toe, set on a packed base.

  • New rectangular concrete patio with straight control joints beside a white brick house and lawn.

    Slab foundation building

    We build slab foundations for garages, additions and new homes, with a packed base and steel rebar tying the slab together so it moves as one piece.

  • Concrete driveway with smooth gray sections and tan decorative concrete leading to white garage doors.

    Foundation installation

    Building or adding on? We form and pour foundation walls for new homes, additions and commercial buildings, working from your plans with you or your builder.

  • Curved brick walkway and concrete retaining walls with steps lead from a dark driveway to a landscaped garden.

    Concrete parking lot building

    We build concrete parking lots for businesses and property owners, poured for the traffic they'll carry and graded so water runs off instead of pooling.

  • A single brown concrete step sits below a house door, surrounded by a gray stamped concrete walkway and river stones.

    Concrete footings

    Footings are the concrete pads under a deck post, porch or wall that carry its weight, and we dig and pour them to your plans on firm ground.

  • A broad stamped concrete patio with rectangular stone patterns borders a raised deck with a wooden fence and seating.

    Foundation raising

    When a house or garage sits too low or has settled, foundation raising lifts it and builds new concrete underneath so it sits right again.

  • A stacked concrete retaining wall topped with a stone cap supports a lantern, with flower beds and lawn behind it.

    Concrete cutting

    Need a doorway in a foundation wall or a trench through an old basement floor? We saw-cut it cleanly so the rest of the slab stays sound.

Why Portsmouth homeowners and builders pick us

Most of what makes concrete hold up happens before the truck arrives, so these are the parts of how we work you'll notice from the first call.

  • The person who bids stays for the pour

    You talk with me from the first visit, I write the estimate myself, and I'm on site when the truck shows up. Nothing gets lost between what we agreed on and what goes into the forms, because the same person carries it through.

  • Sloped lots and tight side yards

    We like the jobs other crews pass on. A sloped yard, a driveway squeezed along the side of the house or a cut through an old basement floor gets a real plan from us, and I'll happily spend the extra hour figuring it out.

  • The reason behind each step

    We tell you why the base gets dug out, why joints get cut and when the slab is ready to use. You'll know what you're paying for, and you'll know what to ask anyone else who bids the job.

  • Permit questions sorted early

    Before we set a pour date, we check what the local building office needs and help pull together the sketches or site plans they ask for, so paperwork doesn't hold up the pour. Call (603) 956-1034 or use our contact form to get started.

How a concrete job goes with us

From the first call to the cleanup, here's how a job usually runs and who you'll be dealing with along the way.

  1. Step 01

    Call or send a message

    Call (603) 956-1034 or send a message through the form, and tell us what you have in mind and where the property is. A rough size and how you'll use the space are plenty for now. We get back to you within one business day to set up a visit.

  2. Step 02

    Site visit and written estimate

    I come out myself and walk the site with you. I'll ask how you'll use the space, where the water goes when it rains and what's under the old slab if there is one. Then you get a free written estimate, with no obligation to book.

  3. Step 03

    Base prep and the pour

    Once you're ready, we sort out any permit questions and pick a pour date with the season in mind. Our own crew digs out and packs the base, sets the forms and steel, then pours and finishes the slab, and I'm there for the pour.

  4. Step 04

    Cleanup and curing

    We cut the joints, clean up the site and haul off the debris. Then the slab needs to cure, the slow hardening that gives concrete its strength, so we'll go over when it's ready for feet and when it's ready for cars before we leave.

What goes under and into every slab

  • The base comes before the finish

    We dig out soft dirt from the subgrade, the ground the slab rests on, and pack a firm base. It's hidden on day one and the first thing a tight budget cuts, but I'd trim the finish before I'd trim that.

  • Water gets checked first

    Before the forms go in, we look at where rain runs off your roof and across the yard. A slab that falls toward the house sends water at your foundation, so we pitch it to carry water away.

  • Pours timed around the heat

    We'd rather pour in the morning than in midday heat, because a top that dries too fast can turn weak and dusty later. Our own crew stays with the finishing until it's done right.

How I came to concrete work

I poured my first concrete patching barn floors and stall pads on my family's farm, then spent years on other crews learning flatwork and foundations. I started Portsmouth Concrete Works in Portsmouth, NH in 2017, and we're fully licensed and insured. Today we handle 16 kinds of concrete work for homeowners, builders and property owners. You can read more about us and how we work.

Concrete questions Portsmouth homeowners ask us

How much does a concrete driveway cost in Portsmouth, NH?

The price depends on the size and thickness of the slab, how much digging out and base work the ground needs, whether an old driveway comes out first and the finish you pick. A tight or sloped lot adds labor, and a plain finish costs less than a decorative one. Your free written estimate gives you the number for your job.

Does stamped concrete cost more than a plain concrete patio?

Yes, stamped concrete usually costs more than a plain broom finish because the pattern, color and extra finishing time add labor. The base work underneath is the same either way, so if you're torn, we can price both.

How long will I be without my driveway after a new concrete pour?

You'll stay off a new driveway or patio while the concrete cures, and the wait before you drive on it is longer than the wait before you walk on it. We'll give you both once we know the mix and the pour day. Before the pour, timing mostly depends on permit questions and the season.

Is Portsmouth Concrete Works licensed and insured?

Yes, we're fully licensed and insured. The City of Portsmouth doesn't issue its own business license, since business licenses come from the State of New Hampshire. Whoever you hire, ask to see their insurance before work starts.

What happens to my old cracked slab when you replace it?

We break it out, haul it away and look at what's underneath before anything new goes in. The old base usually tells us why the slab cracked or sank, whether it was soft dirt, water running under it or missing joints, and we fix that cause in the new base.

Does Portsmouth Concrete Works guarantee its concrete work?

Yes, our work is backed by our satisfaction guarantee. Before we pack up, we walk the finished job with you and go over how to look after it while it cures.

Will my new concrete slab crack like the old one?

Concrete can still crack, but most cracks on old slabs come from a soft base, water running the wrong way or joints that were cut late or skipped. We cut control joints, shallow grooves that give the slab a planned place to crack, on time, and steel rebar helps hold the slab together if a hairline does open.

Do I need a permit for concrete work in Portsmouth, NH?

It depends on the job, so check with the city's Inspection Office, which issues building permits in Portsmouth. Its list names new structures like garages, sheds, decks and pools, but it doesn't settle driveways or patios. In the Historic District, new construction and exterior changes need a separate Historic District Commission application, and that review adds at least a month. Using a city sidewalk or other public way during the work needs an application first too, and we look into all of this before setting a pour date.
