Cracked, crumbling, or uneven concrete floor? We replace and install concrete floors for Claremont garages, patios, and additions - built for local soil conditions and summer heat.

Concrete floor installation in Claremont covers the full process of pouring a new slab for a garage, patio, or residential addition, built on a properly prepared base suited to local soil conditions - most projects run one to three days for the pour and finish, with the full cure period taking about four weeks.
The question homeowners ask most is whether to patch or replace. If your floor has cracks that keep coming back, low spots where water pools, or surface that's flaking apart, the problem is usually coming from the soil underneath - not the surface itself. Claremont's clay-heavy ground expands and contracts with the seasons, and a floor that was poured thin or without proper base prep will keep showing those symptoms no matter how many times you patch it.
We often work alongside garage floor concrete projects specifically, since garage slabs are the most common floor replacement request in Claremont's older neighborhoods - homes built in the 1950s and 60s often have slabs that were poured thinner than current standards and are now well past their useful life.
If you've patched cracks before and they keep coming back - or a hairline crack from last year is now wide enough to catch your shoe - the floor is moving from below. In Claremont, that's usually the clay-heavy soil expanding and contracting with the seasons. Patching won't fix a floor being pushed around from underneath.
Low spots where water collects after rain, or a floor that feels noticeably tilted when you walk across it, means the slab has shifted or settled unevenly. Claremont's dry summers followed by wet winters accelerate this kind of movement in older slabs. A floor that drains poorly can also push water toward your home's foundation.
If the top layer of your concrete is peeling away in flakes or looks rough and pitted, the concrete has started to break down from the inside. This is common in floors 40 or more years old and tends to accelerate once it starts. Resurfacing may buy a few more years, but full replacement is often the more durable long-term choice.
If you're finishing a garage, building a workshop, or adding an accessory dwelling unit, the existing slab may not be thick enough or level enough for the new use. This is a common situation in Claremont's older ranch-style homes, where garages were built for basic storage - not the multi-use spaces homeowners want today.
We pour new concrete floors for garages, patios, workshops, and residential additions throughout Claremont. Every project starts with an on-site assessment of the existing surface and soil conditions - because the preparation underneath the slab is what determines whether your floor holds up for 30 years or starts cracking within a few. For homeowners who want a polished or decorative finish on top of the new slab, we also coordinate with concrete pool decks finishing work where the style fits the project.
Demolition and hauling of the old slab is included in projects where the existing concrete needs to come out first. We handle the permit application with the City of Claremont, schedule pours for early morning during summer months to avoid heat-related curing issues, and give you clear instructions on when the floor is safe to use after the pour.

Two factors make concrete floor work in Claremont different from a generic job: the soil and the heat. Much of the city sits on clay-heavy ground that moves with the seasons - swelling in winter rains and shrinking in the dry summer heat. That movement is the number-one reason floors in older Claremont homes crack and settle. A contractor who doesn't account for it in the base preparation and reinforcement is setting up the floor to fail. The same soils that have been pushing on existing slabs for 50 or 60 years will push on a new one if the prep work isn't done right.
The summer heat adds another layer. Claremont regularly sees temperatures above 95 degrees, and concrete poured in that heat can dry out too fast before the curing process is complete - which leads to surface cracking and a weaker floor. We schedule warm-weather pours for early morning and take steps to keep the surface properly moist during curing. Homeowners in Ontario and Chino face the same heat and soil challenges, and we bring the same approach to every project across the area.
Call or submit the contact form and we'll get back to you within one business day. We'll ask a few questions about your space, current floor condition, and how you plan to use the area - no commitment, just a conversation.
We come to your property, look at the existing floor and soil conditions, measure the area, and ask about the finish you want. You receive a written estimate that includes everything - demolition if needed, the pour, the finish, and permit fees.
For projects that require a City of Claremont permit, we handle the application and account for the one-to-two week processing window in your schedule. We also confirm the pour date with you and let you know exactly how to prepare the space.
The crew arrives early - especially in summer - to pour and finish the floor in one to three days. We give you clear instructions on when to walk on it, when to drive on it, and how to care for it during the 28-day curing period. A city inspector signs off if a permit was pulled, and we walk you through the finished floor before we leave.
Free estimates, permits handled, and a written quote before anyone picks up a shovel.
(909) 788-2719We assess soil conditions at your property before recommending slab thickness, reinforcement, or gravel base depth. In Claremont's clay-heavy ground, that assessment is not optional - it's the difference between a floor that holds and one that cracks within a few years.
Claremont regularly tops 95 degrees in summer. Concrete poured in afternoon heat dries too fast and comes out weaker. We schedule summer pours for early morning and keep the surface moist during curing. The American Concrete Institute provides guidance on proper curing practices at{' '}concrete.org.
The City of Claremont requires permits for most concrete slab work. We pull the permit, coordinate the city inspection, and keep your home's records clean - which matters when you eventually sell. A project done without permits can complicate a sale and leave you liable for corrections.
Your written estimate covers everything: demolition of the old slab if needed, the pour, the finish, and the permit fee. If the scope changes during the site visit - say, the old slab is thicker than expected - we tell you before work starts, not when you get the invoice.
A concrete floor is only as good as the preparation beneath it. We build that invisible foundation the same way we build everything else: to last through Claremont's seasons without cracking or shifting.
