Concrete Contractor in Londonderry, NH - Driveways and Patios Built on a Solid Base
R&S Manchester Concrete Construction is a concrete contractor working in Londonderry, NH. We build driveways, patios, walks, steps, slabs and footings for homes here, and we dig out and pack the base before we pour.
Londonderry: long driveways, stony ground
Londonderry is mostly houses on good-sized lots, from older colonials and capes along the original roads to newer subdivisions, with orchards and open land still between them. Driveways tend to run long, a lot of them were poured or paved years ago, and many of our calls here are about slabs that have sunk, cracked or started holding water by the garage. It's much like what we see next door in Derry and Windham.
The ground is the other half of it. The soil here is full of stone and holds water when it freezes, so on most Londonderry lots the job starts with digging past the topsoil, packing the subgrade, which is the ground the slab sits on, and laying a gravel base over it before any concrete shows up.

Concrete work we do in Londonderry
Concrete driveway building
Long driveways here take plows and frost every winter. We dig out soft soil and pack a solid base so the slab sits on firm ground.
Concrete patio construction
Patios here often sit where water collects after a storm. We check where the water runs and slope the slab away from your house before we pour.
Concrete steps construction
Front steps on older houses here often heave or crumble after years of frost. We break out the old ones and pour new steps on a packed base.
Concrete retaining walls
Sloped yards here push soil and runoff toward driveways and patios. We build concrete retaining walls with drainage behind them, so the water has somewhere to go.
Concrete footings
Sheds, decks and additions here need footings that sit below the frost. We dig them to the depth your plans call for, before framing starts.
Garage floor concrete
Winter slush and road salt drip off cars here and pit older garage slabs. We pour new floors pitched toward the door so meltwater runs out.
Working in Londonderry: permits, prep and price
The permit call on a Londonderry job belongs to the Town of Londonderry's building and zoning office, so before we dig, I check with them about your job and help you pull together what they ask for, like a site plan. If a permit is needed, we either handle it or walk you through it, depending on whose name the office wants on the application, and that review comes ahead of the pour, so it's part of your schedule along with the weather and the cure time. We're licensed and insured, and that's worth asking any contractor to show you before they start. The price moves with the size of the slab, how deep we have to dig to hit firm ground and the finish you pick, and after I walk the property with you, I write up exactly what the job includes.
Spring melt can send a lot of water across a Londonderry yard in a hurry, and ice and snow sit on driveways for months, so the first thing I look at on a walk-through is where the water runs. Most of the sinking, pooling and cracking I see here comes from a slab that falls toward the house or sits on dirt that was raked level instead of dug out and packed. That base is hidden the day we pour and it's the first thing people want to trim from the budget, but it's the part I won't cut, because just like on a kitchen line, the prep decides how the plate turns out. We also cut control joints, shallow grooves that give the slab a planned place to crack, so if a crack comes, it runs along a line we chose. It's the same base-first work we do over in Raymond and the other cities around Manchester.

Concrete ideas for Londonderry homes
Concrete questions from Londonderry homeowners
How much does a concrete driveway cost in Londonderry, NH?
The cost of a Londonderry driveway comes down mostly to its size, how much digging and gravel it takes to reach a firm base, and whether there's an old slab to break out and haul away. Thickness and steel add to it, because a home driveway is usually about 4 inches thick and goes thicker where heavy trucks park, and rebar, the steel rods inside that hold cracked pieces together, adds material and labor. A plain broom finish, the light texture that keeps tires and boots from slipping, costs less than stamped, and I'll put your number in writing after I walk the driveway with you.
How do I find out if my concrete patio or driveway needs a permit in Londonderry?
Ask the building office before anything gets dug up. Londonderry's building permit list covers residential work like additions, sheds, decks, porches and garages, and it isn't limited to those, so a slab job is worth the question. Call us at (603) 314-3764 before you start, and we'll check on your job as part of the estimate.
Does a shed slab in Londonderry need a permit?
A shed under 200 square feet doesn't need a permit in Londonderry, but bigger ones do, and a shed of 200 square feet or more has to sit on footings 48 inches down, the local frost depth. Every shed, whatever its size, still has to meet the setback rules on how close it sits to your lot lines, so we measure from the line before we set forms.
Can I apply for a Londonderry building permit online?
No, building permits aren't on Londonderry's online permit portal, which handles permits like electrical, plumbing, septic and well instead. Each building permit goes in with a $25 application fee.
Which building code applies to a concrete foundation or footing in Londonderry right now?
Through the end of 2026, a permit request can follow either the 2021 or the 2024 code editions, and starting January 1, 2027, every request has to follow the 2024 codes with New Hampshire's amendments. Londonderry still lists the 2021 codes as in effect, while the state's update took effect this past July, which is why both are allowed for now. If your footing or slab plans are being drawn now, ask the building office which edition they'll review them against.
How long does a new driveway in Londonderry need to cure before I can park on it?
You can usually walk on a new driveway after a day or two and drive on it after about a week, while it cures, which is the slow hardening that gives concrete its strength. Cold fall weather slows curing down, so a late-season pour can need longer before your car goes on it, and I'll tell you when it's ready to park on.
