A patio that stays level and drains right
Builder-grade patios around Aurora tend to fail the same way. A thin slab goes down on a few inches of backfill right next to the foundation, and the backfill settles. Within a couple of years the patio tilts toward the house. Water runs back against the wall, freezes in the joint, and heaves the slab a little more each winter. We break these out and find no rebar, a wet clay base, and sometimes a crack that runs straight across the middle.
A good patio starts with the ground. We strip sod, dig out topsoil, and compact road base, especially near the house where fill is the loosest. Then we set forms with a slope of about a quarter inch per foot away from the foundation, add rebar or fiber, and pour a 4,000 PSI air-entrained mix. A broom finish gives you grip when it's wet and costs less than anything fancier.
Typical pricing runs $8 to $12 per sq ft. A 12x16 patio (192 sq ft) usually lands between $1,550 to $2,300. Patios are one of several projects in our residential concrete work, and we can add color or pattern if you want more than plain gray.
Do you need a new patio or just a fix?
Some patios are worth saving. Here's how we tell the difference.
Call soon if you see
- The slab slopes toward the house and water pools against the foundation
- Large cracks with one side higher than the other
- Surface peeling, flaking, or turning to sand under your feet
- Sections that have sunk away from the back step or door
- A patio too small to use, where you want to add on
Usually safe to watch
- Hairline cracks that have stayed the same for a year or more
- Faded or stained concrete that is still flat and solid
- A single crack along a joint, which is where it was meant to crack
- Mild surface wear a sealer can protect
Common patio problems and how we fix them
Tilting toward the house
This is the one that causes real damage. Water against the foundation can seep into the basement or crawlspace. A tilted patio can sometimes be raised, but if it's also cracked through, we'd replace it and set a proper slope the second time.
Cracks and settling
Concrete shrinks as it cures, so some cracks are normal. Wide cracks, or ones with a height difference, mean the base moved. Clay soil is the usual cause. New patios get control joints every 8 to 10 feet so any cracking is straight and tight.
Scaling and surface damage
Flaking is usually from salt and freeze-thaw, or from a surface that was overworked or watered down when it was finished. A fresh sealer protects a good surface. If it's already shedding, resurfacing or replacement is next.
Too plain or too small
Many patios are poured a size too small. We can add a section and match the joints. If you want pattern or color, look at stamped concrete, or decorative concrete like exposed aggregate and saw-cut designs.
How we pour a concrete patio
-
Plan the size, slope, and layout
We mark the footprint, check where water goes, and talk through furniture, grills, and steps. You get a written price first.
-
Remove old concrete or sod
If there's a patio in the way, it gets saw cut and hauled off. Otherwise we strip sod and topsoil. Sprinkler lines and utilities are marked first.
-
Build the base
We compact 4 inches or more of road base, deeper near the foundation or over soft clay.
-
Forms and reinforcement
Forms set the shape and the quarter-inch-per-foot slope. Rebar or fiber goes in to hold the slab together if the ground moves.
-
Pour, finish, and joint
We place 4,000 PSI air-entrained concrete about 4 inches thick, float it, apply a broom finish, and cut control joints.
-
Cure and seal
Foot traffic after a day. Furniture after about a week. Sealer goes on after roughly 30 days.
What affects the price of a concrete patio
Most Aurora patios run $8 to $12 per sq ft. Here's what moves a job up or down.
- Size and shape
Larger patios cost less per square foot. Curves, steps, and built-in seat walls add forming time.
- Site prep
A flat, open yard is quick. Slopes, tree roots, and soft clay near the foundation mean more digging and base.
- Removal of old concrete
Tearing out an old patio runs about $3 to $7 per sq ft. A Remove an old 12x16 patio (192 sq ft) costs $600 to $1,350.
- Finish type
Broom finish is the base price. Stamped concrete runs $14 to $22 per sq ft, and decorative finishes fall in between. For the full breakdown, see the Aurora patio cost guide.
- Access
A gate wide enough for a truck or a short wheelbarrow run keeps labor down. Narrow side yards need a pump.
- Thickness and reinforcement
Four inches handles patio furniture and a grill. A hot tub or heavy equipment needs a thicker slab with more steel.
Building a patio through Aurora’s seasons
Winter
Pouring in freezing weather needs blankets and care. Most patios wait for spring, but design and permits can happen now.
Spring
Spring storms and wet clay can delay digging. We check the ground before we set forms.
Summer
Hot, dry, windy afternoons dry concrete too fast. We pour early in the day and apply curing compound right after finishing.
Fall
Fall is a good pour window. Seal the new patio before the first snow and keep deicers off it that first winter.
Aurora soil, salt, HOAs, and permits
Expansive clay soil
Clay swells with moisture and shrinks as it dries. A patio on thin fill will move. Compacted road base, rebar, and downspouts pointed away from the slab are your best defense.
Deicing salt
Salt tracked in from the street or used on steps can scale a new patio. Skip it the first winter, shovel instead, and apply a penetrating sealer.
HOA approval
Many Aurora HOAs want to approve patio size, location, and color before you build. Setbacks and visibility from the street can matter too. Get approval in writing before the pour date.
City of Aurora permits
Permit needs depend on the project. A patio cover, a retaining wall, or work near a utility easement can each change what the city requires. We confirm with the City of Aurora Building Division for your address before we schedule the pour.
Concrete Patios FAQs
How much does a concrete patio cost in Aurora?
Most patios run $8 to $12 per sq ft. A 12x16 patio (192 sq ft) is typically $1,550 to $2,300. Stamped, colored, and exposed aggregate finishes cost more.
How thick should a concrete patio be?
Four inches works for furniture and a grill. A hot tub, outdoor kitchen, or heavy planter needs more. We add thickness and steel based on what will sit on it.
How long before I can use a new patio?
Walk on it the next day. Light furniture after about a week. Hold off on heavy items and deicers for the first month.
Can a patio be attached to the house?
It can sit against the house, but it should slope away and stay separate from the foundation with an expansion joint. Water running toward the wall is the biggest risk.
Should I seal my patio?
Yes. Seal it after about 30 days of curing and again every 2 to 3 years. Sealing runs $1.50 to $3 per sq ft. Read more on our concrete sealing page.
Do I need HOA approval for a patio?
In most Aurora HOAs, yes, especially for new patios or any change in size or color. Ask for approval in writing and keep a copy.
