Concrete Patio Construction in Union City CA - a slab that drains away from your house
Cracked old slab, or a back door that opens onto mud? We plan the gravel base and slope so rain runs away from your house.
What does it take to build a concrete patio in Union City?
Concrete patio construction in Union City means we form, pour and finish a flat concrete slab beside your house, on a packed gravel base and with a slight slope. You get an outdoor surface that holds your furniture, or even an outdoor kitchen, and sends rain away from your walls.
Most people who call us about a patio have a slab that's cracked and sinking at one end, water pooling against the back wall after rain, or a back door that opens onto bare dirt. The price moves with the size of the patio, how much digging and base work your yard needs, whether you want steel for heavy items and how plain or decorative the finish is. The schedule turns mostly on permits, the weather and how much ground prep the site needs before we can pour. When we meet, I'll write an estimate that lists what's included and what isn't, and if your patio needs a permit, we take care of the application and inspections with the city.
How we handle concrete patio construction
I plan the part you won't see first. We mark out the patio and dig the loose dirt down to the subgrade, the firm ground the slab rests on. Then we spread gravel and pack it down, so the slab sits on a solid bed that lets water drain instead of on raked dirt that settles. We set the slope before the forms go up so rain runs away from your house, and we decide where that water goes once it leaves the slab. If you're thinking about an outdoor kitchen or heavy furniture, we'll talk about adding rebar, the steel bars that tie the slab together, before anything is poured. We try to pour outside the midday heat, because a slab that dries too fast tends to end up with a weak, dusty top. Then we finish the surface and cut control joints, shallow grooves that give the slab a chosen place to crack as it shrinks. After that the concrete cures, the slow hardening that gives it strength, and I'll tell you when it's ready for chairs and a table.
A plain patio is where most people start, but if you'd like the look of stone or brick, our stamped concrete services press a pattern into the same slab. When the budget gets tight, the finish is the place I'd trim before the base, since nobody sees the gravel on day one but everyone notices a patio that sinks. Many patios also need a path from the driveway or side gate, and our concrete sidewalk building work lets us pour that walk so it meets the patio at the same height.
Permits, grading and patio work in Union City
Union City requires permits for building, remodeling or improving a home, and grading permits for projects that grade, dig, fill or clear soil. A patio base starts with digging and filling, so I confirm with the city what your plan needs before we break ground and keep you posted as it moves along. If your patio or the path to it reaches the public sidewalk, the city also asks for an encroachment permit, its permit for work in the public right-of-way, and we add that step to the job.
We're based in Union City, and the older patios we're asked to replace here and on jobs in Fremont and Hayward are often poured tight against the house with little fall, so rain runs toward the foundation. It's worth checking your own yard too. If water stands on the lawn after a storm or the dirt turns sticky when it's wet, you may have clay-heavy soil, and one patio maker's guide says a packed gravel base matters for drainage on that kind of ground, so tell me what you see and I'll plan the base around it.
How a patio job works
Call and set a visit
Call (510) 319-6825 or send the form, and we'll set a time for me to come out. I look at the site and listen to what you have in mind for the space.
Walk the yard together
I measure, check where the water runs now and ask how you'll use the patio, then write an estimate that lists what's included and what isn't. We talk through choices like steel and the finish before you decide anything, so you know what you're paying for.
Prepare the ground and pour
Once you're ready, we handle any permit steps, dig out and pack the base, then pour and finish the slab. Fresh concrete can cause severe burns on skin and eyes, so please keep children and pets clear of it while we work.
Walk the finished patio
When the work is done, I walk the patio with you and explain how to care for it. You'll know what to look out for while it cures and when it's ready for use.
Get a written estimate for your patio and walkway
We reply to every call and message within one business day, and we'll set a time for me to come out and see your yard. The estimate is free, done on site and comes with no obligation and no pressure to book. It's written out so you can see what's included and compare it with other bids.
Questions before you book patio construction
How much does a concrete patio cost in Union City?
A residential concrete patio, installed, usually costs about $7.50 to $13 per square foot across the San Francisco area. Where yours lands depends on the size, how much digging and base work the ground needs, any steel and the finish you choose. Your written estimate gives you your own figure.
Does my concrete patio need rebar?
Not always, but rebar is recommended when the patio will carry heavy items like an outdoor kitchen or large furniture. A lighter-use patio can often go without it. If you're planning a kitchen, ask for rebar in every quote you get, ours included.
Who is allowed to build a concrete patio in California?
A contractor holding California's concrete classification can build your patio, because that license covers flat concrete work like a patio slab. A general building contractor can also take the job if it holds that classification itself or hires a licensed concrete contractor to do the work. Ask each bidder which license they hold before you sign.
How do I keep a new concrete patio from cracking?
Make sure control joints are planned into the layout, since one patio maker's guide says any patio larger than 10 feet by 10 feet will definitely need them. The joints decide where the slab cracks as it shrinks, so the line lands somewhere straight and chosen. Ask each bidder where the joints will fall, and I'll show you where we plan ours before we pour.
What is the best finish for a concrete patio if I want good footing?
A broom finish, made by dragging a stiff broom across the surface before the concrete fully hardens, gives a plain patio a slip-resistant texture. The fine ridges grip shoes when the slab is wet. Ask for a broomed surface by name in your quote if footing matters to you.
Do I need a permit to build a patio in Union City?
You may, because Union City requires grading permits for projects that dig, fill or clear soil, and a patio base starts with digging. We check what your project needs with the city before we start and take care of the application and inspections.
