Pleasant Hill homes, yards and the ground under them
Pleasant Hill is mostly single-family neighborhoods between Concord and Walnut Creek, and a lot of our calls here are about the concrete that came with the house, like a driveway that's cracked into pieces, a back patio that's tipped or front steps pulling away from the porch. Some lots are flat and easy for a truck to reach, while others slope or tuck the yard behind the house, where every load goes in by wheelbarrow. Closer to the freeway and around Contra Costa Centre, there are more apartments and shops, and that's where most of our small property owners call from.
Older slabs here were often poured right on the dirt with little base under them, so when we replace one, we usually start by digging out what's underneath, not just what's on top.
Concrete work we do in Pleasant Hill
Concrete driveway building
When an older driveway has cracked, sunk at the garage or started pooling water, we tear it out, dig out and pack the base, and pour new.
Concrete patio construction
A backyard patio has to shed water away from your house, so we work out where the rain will run before we set a single form.
Stamped concrete services
Stamped concrete presses a stone or brick pattern into the surface while it's soft, for a front walk or patio that should look like more than plain gray.
Concrete sidewalk building
Side yard paths and front walks get lifted by roots or settle into a trip edge, and we replace the bad sections or the whole run.
Garage floor concrete
A garage floor that's cracked, stained or sloping the wrong way can be broken out and repoured, with the base packed and the slab pitched toward the door.
Decorative concrete
Color, a scored pattern or exposed aggregate, where the top is washed back to show the stone, can dress up an entry or patio without switching to pavers.
Concrete retaining walls
On sloped yards, a concrete retaining wall holds the soil back so you get a flat spot, with drainage behind it so water doesn't push it over.
Concrete floor installation
For a workshop, studio or addition, we pour an interior floor over a packed base and finish it flat enough for the flooring or use you have planned.
Concrete pool decks
Around a backyard pool, the deck needs a surface that isn't slick when wet and a slope that sends splash water away from the pool and the house.
Concrete steps construction
Front steps on older homes often pull away from the house or crack at the edges, so we pour new ones with every step the same height.
Slab foundation building
For an addition or a backyard unit, we pour the slab foundation on dug-out, packed ground, with rebar inside, steel bars that keep cracks from pulling apart.
Foundation installation
When an addition, a garage or a larger outbuilding needs a full foundation, we dig, set the forms and steel, and pour it to the approved plans.
Concrete parking lot building
For small property owners with parking behind a shop or a few apartments, we pour a thicker slab built to take cars coming and going all day.
Concrete footings
A patio cover, a fence or a small wall needs footings, concrete buried under each post or wall, so the weight rests on firm ground instead of topsoil.
Foundation raising
When a corner of the house has dropped and doors start sticking, foundation raising lifts that section back up and sets new support under it.
Concrete cutting
We saw-cut openings, trenches and clean edges in existing slabs, so a plumber can reach a line or a damaged section can come out without breaking the rest.

What working in Pleasant Hill takes on our end
Permit applications in Pleasant Hill go to the city's Permitting Office. The Building Division says any work that physically changes or adds a structure needs a permit, and it lists ground work like driveways, walkways and patios as not needing a building permit. When a job does need a permit, the city's review sets the start date more than our calendar does, so I plan around it, and if you want to ask a permit question yourself, the Building Division takes calls at (925) 671-5200. There are also two things you can check about any contractor before you hire. The state requires a license from the Contractors State License Board for any job that needs a permit, uses extra workers or totals $1,000 or more for labor and materials together. The city also requires a business license from every contractor working here, including ones based outside the city like us. We're licensed and insured, and we check with the city on your address and handle the permit paperwork when a job needs one.
Pleasant Hill sits right beside Concord along Interstate 680, so our crew is close, and we do the same kind of driveway and patio work here as we do in Bay Point. What moves the price is mostly hidden work and access: how much old concrete has to come out, how deep we dig and pack the base, whether the truck can reach the forms or we have to carry the concrete into a backyard, and the finish you choose. The schedule turns on any permit, the weather and curing, which is the stretch of days a new slab needs to harden before it can take weight. Your written estimate spells all of that out for your job.
Why slabs here crack, settle and hold water
A city document notes how common clay soil is across Pleasant Hill. Clay swells when winter rain soaks it and shrinks as it dries out in summer, which lifts and drops any slab that sits right on it. That's a citywide finding, not a test of your lot, so I look at the ground at your house before I say what it needs. On most jobs, we dig out the soft, loose material and pack a solid subgrade, the layer the slab rests on, because a slab is only as steady as what's under it. If the budget is tight, I'd rather you pick a plain broom finish, the light texture that keeps it from getting slick, than cut corners on the base. You can dress up the surface later, but you can't fix the base without tearing the slab out.
Plenty of the older driveways and patios we see here pool water or tip back toward the house, because nobody checked where the rain would go before the pour. We slope the new slab away from your foundation and toward a spot that can take the water, so a winter storm runs off instead of sitting against the house.
What to expect when you hire us in Pleasant Hill
Here's how a job runs, from your first call to the walk-through, so you know what happens at each step and when you need to be home.
Call or send the form
Tell us what you're dealing with by calling (925) 536-0945 or sending the form, and we'll set a time for me to come out. A rough idea of the size and a note about what's wrong is plenty to start.
Walk the site with me
I come out myself, look at the slab, the ground and where the water runs with you, and explain your options before putting the estimate in writing. It helps if you're home for this visit, because the estimate shows what each part of the price pays for, and you can ask about any of it before you decide.
We handle permits and pour
Once you're set, we sort out the city side, and then I work on site with our form setters and finishers. Pleasant Hill allows construction from 7:30 a.m. to 7 p.m. on weekdays and from 9 a.m. to 6 p.m. on weekends, so in summer we start pours as early as that allows, before midday heat dries the top too fast and leaves it weak and dusty.
Walk the finished job together
When the forms come off, I walk the job with you and go over when you can walk on it and when you can drive on it. Satisfaction guaranteed on every job.
Questions about concrete work in Pleasant Hill
How much does a new concrete driveway cost in Pleasant Hill?
I can't give you a fair number until I've seen the driveway, because the size, the old concrete coming out and the base work the ground needs make up most of the price. Thickness, the rebar inside, a stamped or colored finish instead of a broom finish, and whether the truck can reach the forms also raise or lower it. On this clay ground, the base is often the biggest line, and it's the one I'd keep, so your written estimate breaks every part out.
Do I need a permit to replace my driveway apron at the curb in Pleasant Hill?
You may, because the city says ground work that reaches onto city property, like the street, curb or gutter, can require an encroachment permit through the Engineering Division. That's separate from the building permit question, so when your driveway meets the street, we get it sorted before the old apron comes out.
Do I need a permit to pour a slab for a shed in Pleasant Hill?
The city looks at the shed going on the slab, and a one-story detached shed of 120 square feet or less skips the building permit but still needs a Planning Zoning Permit. A shed with electricity needs a building permit, and a bigger shed loses the exemption, so tell me what's going on the slab when I come out.
Does a flood zone change concrete work on a Pleasant Hill property?
It can, because the city says improvements in the floodplain may require a Floodplain Development Permit. A city handout counts about 700 homes inside FEMA's flood zones here, so I check your address against the city's floodplain information before we plan the job.
How do I keep a new patio from cracking like the old one?
Concrete does crack, so the real goal is to control where it cracks, and that comes down to the base under the slab and control joints, shallow grooves cut into the top that give it a planned place to break. We cut the joints while the concrete is still fresh and set them where the slab wants to crack. With the packed base I described above, cracks usually stay thin lines in the joints instead of running across the middle.
How long does a new driveway take before I can drive on it?
You'll be able to walk on it well before you can drive on it, because concrete keeps gaining strength for days while it cures, and a car weighs a lot more than you do. I give you the dates for your pour at the walk-through, and hot or cool weather can shift them a little, so plan on parking in the street for a while after we pour.
