What does it take to build a new concrete sidewalk in Merrimack?
Concrete sidewalk building in Merrimack means digging out the old walk or the lawn, packing a firm base and pouring an outdoor slab that's placed and finished to stand up to freezing, thawing and winter salt, so the top of your walk stays sound.
Most people call me when the old walk has started to flake, crack or tip, or when they're tired of cutting across the lawn to get to the front door. What moves the price is the size of the walk, how much old concrete we break out and haul away, how deep we have to dig to reach good ground, the finish you pick and whether the walk runs out to the road. The schedule mostly turns on the weather, on what the ground looks like once it's open and, for a walk that reaches the road, on Merrimack's go-ahead for that strip. I'll give you a figure for your own walk when I come out and see the spot.
How do you know your sidewalk needs replacing?
Top layer flaking off
When the surface peels away in thin flakes and leaves the stones showing, that's scaling, the top skin of the concrete breaking up. It usually comes from salty water sitting on a walk that wasn't made or finished for it, and every winter it eats a little deeper until the walk is rough underfoot.
Puddles that turn to ice
If water still sits on the walk the day after rain, or the end by the driveway stays wet under the plow pile, the slab is flat or tipped the wrong way. That water freezes into a slick patch on cold nights and speeds up the flaking.
Cracked, raised or sunken slabs
Slabs that have heaved or dropped so one edge sits higher than the next usually mean the dirt under them was raked level instead of dug out and packed. Waiting leaves you a trip edge that gets worse with time and, if the slabs tip toward the house, water running at your foundation.
How we build a concrete sidewalk
Before anything else I look at where rain runs and where the plow and your shovel leave the snow, because we shape the walk so water sheds off it instead of keeping it wet. If the walk reaches the road, we check with the local office about that strip before we dig. Then we break out the old walk, dig down to firm subgrade, the ground the slab actually sits on, and pack a gravel base in layers so the walk doesn't settle with the dirt. We set the forms with a pitch to carry water away, time the pour so we're not racing the midday heat, and give it a broom finish, a light texture that gives your shoes grip when it's wet. We cut control joints, shallow grooves that give the concrete a straight line to crack along instead of a random one, and let it cure, which is the wait while it gains strength before you use it. The base is the part you'll never see and the first thing some crews cut to save money, and I won't cut it, because a nice finish on a soft base is a crack waiting to happen. I spent years in kitchens before concrete, and a plate is only as good as the prep, same as a walk.
Sidewalks often tie into other concrete. If the walk starts at the garage and that floor is cracked or sinking, we can pour new garage floor concrete in the same stretch so the two meet at an even height. If you want more than plain gray out front, decorative concrete adds color, a stamped border or a different texture to the walk.
Broom-finished gray walk
This suits most front and side walks, because the texture grips well in rain and slush and there's nothing extra to wear off or maintain. It's also the plainest way to put your money into the base, where it does the most good.
Walk with color or a border
This suits a front entry people see from the street, where a tinted walk or a stamped edge ties in with the house. It costs more, and a dressed-up surface usually needs more upkeep to keep looking right.

What happens once you call us about a sidewalk?
Here's how a sidewalk job runs from your side, from the first call to the day you walk on it.
Call or send the form
Call (603) 377-5028 or send the form with a few lines about the walk. We'll set a time to come look that works for you.
I walk the spot with you
I look at the old walk, the ground and where water and snow end up, and ask how you use that path day to day. Before I leave, you get an estimate that lays out the tear-out, the base, the finish and the price, so you can compare it line by line.
We prep, pour and finish
Once you say go, we get any permit paperwork moving, dig out and pack the base, and I'm there with our crew for the pour and the finish. Before we leave, I tell you how long to stay off it while it cures and what to watch for that first winter.
Why Merrimack homeowners call Quality Merrimack Concrete for sidewalks
I look at every walk myself
I come out, write your estimate and then run our own crew on site for the work. Nothing gets lost between the person who priced your walk and the people building it.
In business since 2013
I learned this trade beside an older finisher after years on restaurant lines, where prep and timing decide how the plate turns out. Concrete is no different, which is why we don't hurry the base or the finish.
Licensed and insured on your job
We're licensed and insured. That matters on a sidewalk because we're digging near your foundation, across your lawn and sometimes in the public strip by the road, and you shouldn't carry that risk.
If your walk is flaking, holding water or tipping toward the house, tell us about it or call (603) 377-5028 and I'll come take a look.
Sidewalks, driveways and the road strip in Merrimack
In Merrimack, the public right-of-way covers the road and the strip between it and your property line, and Merrimack's Right-of-Way Permit is required for any work that digs into or disturbs it. Its examples include putting in or repairing sidewalks and curbs, building or moving a driveway and taking out trees, so a walk that runs to the road, a job that also changes the driveway or a tree in that strip all bring it in. When your walk reaches that far, we start by checking with the local office about the strip and help get the paperwork moving. That office decides what your job needs, and we work to what it asks.
Around here we often replace walks that were poured on raked dirt beside the driveway, and the corner where the two meet is usually the first piece to drop or crack. We dig that corner out with the rest and pack it the same way, so the walk and the driveway edge sit at one height when we're done. We see the same tired front walks on jobs in Manchester and Nashua.
Questions about concrete sidewalks in Merrimack
How much does a new concrete sidewalk cost in Merrimack?
Across the US, an installed new concrete sidewalk usually costs about $6 to $15 per square foot. That's a national figure, not our price. For a number on your own walk, I'll come out and measure it.
Does Merrimack require a permit for sidewalk work?
Yes, for any part of the walk in the road strip, because Merrimack requires a Right-of-Way Permit for sidewalk work there, as covered above. We check with the local office about that strip before we dig and help get the paperwork moving, and that office decides what the rest of your job needs.
What is the best concrete for a sidewalk that freezes and thaws?
Air-entrained concrete, which has tiny air bubbles mixed through it that give freezing water room to expand. Industry guidance says concrete exposed to freezing and thawing must be air-entrained, so ask any contractor you're comparing, us included, to confirm the estimate calls for it.
Can I put salt on my new concrete walk?
Not the first winter. Industry guidance says to skip deicers on a new walk for its first winter, and surface flaking, the most common frost damage to concrete, is tied to de-icing salt. Plan to shovel early that season and keep the plow pile off the walk.
What causes a concrete sidewalk to flake and peel?
Usually salty water sitting on the surface, on a walk whose mix or finish wasn't right for winter. Poor drainage that lets water or salty water stand on a walk makes the wear far worse and can start that flaking, which is why we spend so much time on where the water goes. Guidance also calls for finishing at the right time and warns against steel trowels on outdoor slabs, so ask any crew how they'll finish yours.
How do I take care of a new concrete sidewalk?
Sealing the surface is the main upkeep step after that first salt-free winter. Industry guidance suggests a commercial sealer or a mix of boiled linseed oil and mineral spirits, so ask whether sealing is part of the job or left to you. I'll go over that with you at the estimate, along with what to watch for after we leave.
Concrete work that often goes with a new walk
Garage floor concrete
When the walk starts at the garage, a cracked or sunken garage floor is often the next problem, and doing both together keeps the step between them even.
Decorative concrete
For a front walk people see from the street, color, a stamped border or a different texture can make plain concrete fit the house better.
