Foundation installation in Manchester NH - the right base for the house you're building
Planning a new house or addition and torn between a basement, slab or crawl space? We'll help you choose, then build it.
What goes into putting a foundation under a new house in Manchester?
Foundation installation in Manchester, NH means building the base a new house or addition sits on, usually a full basement, a slab or a crawl space. The type you pick shapes what it costs, how much space you get below and how that area behaves for as long as you own the place.
Most people who call us about a foundation are building a new house, adding on or putting up a rental or a small shop, and they've got a lot, a plan and plenty of questions about what goes underneath. The price moves mostly with the type and size of the foundation and how much drainage and grading the lot needs, and the schedule turns on the season and the city's sign-off, with the estimate spelling out what's included for your lot. If a slab turns out to be the right call, our slab foundation page goes deeper on that one. Before anything gets dug, we check with the city's Building Division about your job and help you put together what it asks for, like a site plan.

Foundations, footings and the concrete around them
How we handle foundation installation
I start by helping you weigh a basement, a slab or a crawl space against your budget and how you'll use the space, because that choice sets almost everything after it. Then we lay out the house, dig to the depth the design calls for and pour the footings and walls. We plan the drainage along with the walls instead of after them, because water building up in the soil from weather, a rising water table or the house's own systems can push far harder on a wall than it was built to carry. Once the walls are up, we brace them before the backfill, the dirt pushed back against them, goes in, since a wall that isn't held at the top and bottom can get shoved out of line.
Footings are the wider concrete base the walls stand on, and we also pour concrete footings on their own for additions, porches and decks. For landlords and small business owners putting up a building, we can handle the concrete parking lot out front too, so one crew knows how the grading and water work across the whole site.
Why Manchester owners call R&S Manchester Concrete Construction for foundations
Running our own crew since 2017
I learned concrete on other people's crews and started ours in Manchester in 2017, after years on restaurant lines taught me that prep and timing decide how things turn out. On a foundation that means the digging, the forms and the drainage get the most care, because they're buried once the house goes up.
I quote it, then I'm there
I walk your lot and write the estimate myself, and our own crew does the work with me on site. The person who wrote up your job is the one watching the forms and the pour.
Licensed, insured, satisfaction guaranteed
We're licensed and insured, which matters on a job with an open hole and heavy equipment on your lot. Your satisfaction, guaranteed.
Planned to Manchester's frost depth
Manchester's local code amendments list a frost line depth of 4 feet as a design figure, and when a new house or addition goes up, the city wants the lot graded in a way that protects the property next door. We plan the foundation's depth and the grading around it together, and we confirm the current rules with the Building Division before we dig.
On a foundation, what's decided before the pour counts for more than the pour itself. Call (603) 314-3764, email office@manchesterconcreteconstruction.com or send us your project details with the lot address, what you're building and the foundation type you're leaning toward.

What happens after you call about a foundation in Manchester?
Call or send your details
Call or use the form with your lot address, what you're building and any plans you already have. We'll set up a time to meet you at the site.
Walk the lot together
I come out, walk the site with you and listen to what you have in mind for the space under the house. You get a written estimate that shows what's included, so you know what you're paying for before you decide anything.
Sort permits, then build
Once you say go, we sort out the permit side with you and pick a pour date that suits the season. Then our crew digs, pours, drains, braces and backfills in that order.
Walk the finished foundation
When the work's done, we walk it with you and point out what we built below grade. We also go over how to look after it while the rest of the house goes up.
Foundation questions from Manchester owners
What is the best foundation type for a new house in Manchester?
A basement fits best if you want usable space below the house, a slab if you want the simplest build and won't need to get underneath later, and a crawl space sits in between. A basement costs the most, and a crawl space can be a good middle ground or a moisture problem down the road, depending on how it's handled. Weigh the space you want against your budget and the upkeep you're willing to take on.
How do I make sure my foundation goes in before winter in New Hampshire?
Start early in the year, because builder guidance says the foundation should be finished and the house closed in and heated before freezing weather, as in normal building practice. For a Manchester project, the earlier you call, the more room we have to get the paperwork done and pick good pour dates ahead of the cold.
Who approves foundation plans in Manchester NH?
The city's Building Division handles building plan review, permit approval and field inspections in Manchester. If your job needs a permit, we either take care of it or walk you through it, depending on whose name the office wants on the application.
Will a new concrete foundation crack?
Some cracking in concrete can't be prevented, but preventive steps can greatly reduce or control it, and most cracks are no cause for alarm. A fair question for any contractor is which steps they take, and ours start with the drainage and wall bracing described above.
How much does foundation installation cost in Manchester NH?
There's no set price, because the type you pick is the biggest swing, followed by the footprint, the depth and how much drainage and grading the lot needs. I'll put real numbers on those once I've seen the site. If the budget's tight, I'd trim something upstairs before I'd trim the footings or the drainage, because those are buried on day one and there's no going back for them.
Can I use a shallow foundation instead of digging below the frost line?
Possibly, on the right house and lot. National builder guidance describes a frost protected shallow foundation that uses carefully placed insulation to warm the soil, allowing depths as shallow as 16 inches in almost all of the continental U.S., and it suits slab-on-grade homes on lots with moderate to low slopes best. Whether it's accepted for your Manchester job is a question for the Building Division, and we're glad to ask it with you.

Concrete footings
Additions, porches and decks often need their own footings set below the frost, and pouring them with the same crew keeps the depth and layout consistent.
Concrete parking lot building
If your new building is a shop or rental with parking out front, the lot needs the same attention to base and drainage that the foundation got.
