Randolph homes and the concrete jobs we see
Most of our Randolph calls come from homeowners, and they sound a lot like the ones we get next door in Braintree and Holbrook. A driveway has cracked and dropped where it meets the garage, or the front steps have pulled away from the house. Sometimes a patio out back tips toward the door, so every storm sends water at the foundation. Other calls come from small property owners and builders who need a slab or footings for a garage or an addition.
Plenty of houses here still have the driveway or walk that went in when the house was built, and when we break one out, the base under it is often thin or mixed with soft fill. That's why a Randolph job usually goes deeper than people expect, with digging out and packing before any forms go up.
Concrete services for Randolph homes and properties
Concrete driveway building
When an older Randolph driveway has cracked, sunk at the garage or started holding puddles, we break it out, dig out the soft base and pour new.
Concrete patio construction
A patio out back gives you a flat, dry place to sit, and we set its pitch so rain runs into the yard instead of toward your foundation.
Stamped concrete services
Stamped concrete gives a patio, walk or pool surround the look of stone or brick in one solid slab, with no separate pieces for frost to push up.
Concrete sidewalk building
A front walk that has tipped or broken into trip edges is worth replacing, and we pour the new one with a slight pitch so rain runs off it.
Garage floor concrete
If your garage floor is cracked, stained or pitched the wrong way, a new slab gives you a flat, sound floor that drains toward the door.
Decorative concrete
Colored, scored or textured concrete can make a plain front entry or patio match the house, and I'll tell you which finishes stand up to our winters.
Concrete retaining walls
Where a yard slopes toward the house or a driveway cuts into a grade, a poured retaining wall holds the soil back and gives you usable flat ground.
Concrete floor installation
Basements, workshops and additions need a level floor inside, and we pour it over a packed base so it stays flat under shelves, tools and furniture.
Concrete pool decks
A pool deck stays wet all summer, so we give it a broom finish, a light swept texture for grip, and pitch it to carry water off.
Concrete steps construction
Front steps that have cracked, crumbled or pulled away from the house are a fall waiting to happen, so we rebuild them on a solid base.
Slab foundation building
Owners and builders adding a garage, shed or small addition call us for slab foundations, with rebar, the steel bars that hold concrete together, set inside.
Foundation installation
For a new house or addition, we form and pour the foundation walls and check them against the plans before anyone builds on top of them.
Concrete parking lot building
Small businesses and apartment owners in Randolph call us for parking areas poured thick enough for daily traffic and pitched so water doesn't sit in them.
Concrete footings
Decks, porches and additions rest on footings, the concrete pads under posts and walls, and we dig and pour them to what your plans call for.
Foundation raising
When a corner of a house or slab has dropped, raising it can bring it back toward level, and I look at what's underneath before recommending it.
Concrete cutting
Need an opening in a basement wall or a strip of slab removed for new plumbing? We saw-cut clean edges so the concrete around it stays sound.

Permits and contractor checks for concrete work in Randolph
The Town of Randolph issues the permits for building and paving work, and they have to be issued before any work begins. More than one department or board can review a request, so that review usually sets how soon we can pour. The state also wants a licensed construction supervisor or a registered design professional overseeing construction on one- and two-family homes. Anyone working on an existing, owner-occupied home with one to four units has to be registered as a Home Improvement Contractor, and you can check that before you hire. That registration doesn't cover new construction, buildings with more than four units, or investment, vacation and second homes. A Randolph business certificate isn't a license at all, as Randolph says itself.
When a job needs a permit, we pull it ourselves, and I check with the building office before we set a date so the paperwork isn't on you. We're fully licensed and insured, and we do the same work in Dedham and Canton. The price here mostly turns on what's under the old slab and how much of it has to come out, and then on size, thickness, any steel inside and the finish you pick. The schedule turns on the permit review and the weather, because we won't pour into a hard rain or a cold snap. Your written estimate spells out what's included for your own job.
What wears down driveways and patios in Randolph
State guidance expects heavier rain ahead, enough that it may exceed what drainage systems, culverts and sewers can carry. When water has nowhere to go, it sits against driveways and soaks the ground under them. Wet, soft ground is how a slab settles and cracks, so I check where your yard sheds water before we form anything. We pitch every slab away from the house and dig out and pack the subgrade, the soil the slab rests on, until it's firm.
Then there's winter. Water that gets into a crack freezes, swells and pries it wider, so a small crack left alone can become a broken section in a few seasons. We cut control joints on the day of the pour. They're shallow grooves that give the slab a planned place to crack, so any cracking runs in a straight line where nobody notices.
How a concrete job runs when you call us in Randolph
Here's what happens from your first call to the day you can use your new slab, and what you get from us at each step.
Call or send the form
Call (617) 691-5008 or use the form, and we'll set a time for me to come out. It helps if you're home so we can walk the spot together.
I come out and measure
I look at the site, measure, check where the water runs and talk through what you want. You get a written estimate that spells out what's included, so you can see what each part of the price pays for before you decide.
We prep, pour and finish
We pick a pour date with the forecast in mind, then dig out, pack the base, set the forms and pour. If the permit calls for an inspection, we book it by phone with the building department, for the same day or a scheduled date.
Learn how to care for it
Once the pour is done, I walk you through caring for the new concrete, what to keep off it and for how long. Bring your questions, because that's the best time to ask them.
Questions about concrete work in Randolph
How much does a new concrete driveway cost in Randolph, MA?
The price comes down to the driveway's size and thickness, how much old concrete and soft base has to come out, and the finish, so I can only give you a real number once I've seen it. The base is hidden on day one, which makes it the first thing people want to trim, but it's the last place I'd cut, because a nice finish on a weak base cracks and sinks just as fast. If the budget is tight, ask me to price a plainer finish before you ask me to skimp underneath.
Do I need a permit for a shed slab in Randolph, MA?
A small shed may not need one, because Randolph's permit page lists one-story sheds of 120 square feet or less as exempt when they sit outside wetland areas. A bigger shed, or one near a wetland, needs a closer look. Either way, I check with the building office before we pour the slab.
How do I know if my patio or driveway project in Randolph needs wetland review?
It needs review if the work is within 100 feet of a swamp, marsh, pond, vernal pool, forested wetland or intermittent stream, or within 200 feet of a stream that runs year round. The Conservation Commission reviews that work, and digging out for a slab is the kind of earth disturbing work it looks at. Wetlands often look dry in summer, so a low spot that floods in spring may count even if it's lawn in July. If you're near one, the process is to apply, go to a public hearing and get approval before work starts, and we plan the pour date around that.
How long does new concrete take to cure before I can drive on it?
You can walk on a new slab well before you can drive on it, and I give you the timing for your own driveway on pour day. Curing, the slow hardening concrete does in its first weeks, runs slower in cool weather and faster in the heat. Parking on it too soon is one of the common ways a good slab ends up with cracked edges, so it's worth waiting the extra day.
What causes a concrete driveway in Randolph to crack and sink?
Usually it's the base. When the base is raked level instead of dug out and packed, it settles with the dirt, and the slab cracks as it goes down. Water running toward the slab softens that base further, joints cut late let cracks pick their own spots, and a midday pour in the heat can leave a weak, dusty top that chips. We dig out and pack the base, pitch the slab away from the house and pour early in the day.
Will my new concrete patio crack like the old one did?
It can still get a hairline crack, because all concrete shrinks a little as it hardens. The control joints we cut give that crack a straight line to follow, and the packed base keeps the slab from sinking and splitting the way a lot of old patios here have. That's the honest answer, and I'd be wary of anyone who promises concrete that never cracks.
