Concrete Garage Floor Contractor in Durham, NC

Concrete garage floor costs vary based on square footage, thickness, reinforcement, finish, and whether we are tearing out an existing floor or pouring new. For most residential garages in the Durham area, you can expect a range between $8 and $16 per square foot for a standard 4-inch broom or trowel finish. Thicker slabs for RV bays, workshops, or heavy-load garages cost more because of the added materials and reinforcement. Replacement projects also include tear-out and haul-away costs. We provide detailed written estimates after a site review so you know exactly what your project involves.

For most residential attached garages in Durham, NC, 4 inches of concrete is the standard minimum for cars and light trucks. If the garage will store an RV, boat trailer, work truck, or heavy equipment, we typically recommend 5 to 6 inches with additional reinforcement. Workshops with heavy tools or a lift also benefit from thicker slabs. During the site visit, we ask how you use the garage and recommend a thickness that fits both the load and your budget.

A standard residential garage floor pour usually takes one to three days of active work. Day one covers site prep, forming, and reinforcement. Day two is the pour, leveling, and finishing. Day three, if needed, covers curing prep and cleanup. If we are tearing out an existing floor, that adds one to two days to the front of the project. Foot traffic on the new floor is usually fine after 24 to 48 hours, and vehicles can typically drive on it after 5 to 7 days of curing.

Yes. Garage floor replacement is one of our most common projects. Older floors often develop cracks, sink, heave, or fail at seams after years of use. We break up the existing concrete, haul away the debris, prep the base properly, and pour a fresh floor sized for how you actually use the garage. It is one project with one point of contact, not multiple contractors.

Yes. Detached garages, standalone workshops, hobby shops, and outbuildings are a regular part of our work. Detached structures need their own site prep, base work, and slab pour, plus attention to drainage since they usually sit away from the main house. We handle new pours for new construction and replacements for older detached structures that have failing floors.

We install concrete garage floors with several finish options depending on the look and function you want. A broom finish gives good traction and a clean, working look for everyday garages. A smooth trowel finish gives a sleeker, easier-to-clean surface for showrooms, hobby spaces, or garages that see foot traffic more than vehicle traffic. Integral color can be added to the mix for a warmer look. Decorative options like stamped concrete are also available for garages that will be more visible or serve as show-quality spaces.

Yes. Most residential garage floors benefit from some level of reinforcement to handle vehicle weight, temperature changes, and long-term wear. Wire mesh works well for standard residential garages storing cars and light trucks. Rebar or heavier reinforcement goes into slabs supporting RVs, trailers, work trucks, or heavy workshop equipment. During the estimate, we look at how you use the garage and recommend the right reinforcement for the load.

Yes, and drainage slope is one of the most important design details on any garage floor. A subtle slope from the back of the garage toward the door lets water flow out when vehicles bring in rain, snow, or moisture. Without proper slope, water pools inside the garage, leading to staining, rust on tools and vehicles, and slip hazards during colder months. We plan the slope as part of the site visit and pour it into the finished floor.

Yes. RV bays, boat trailer storage, and heavy-vehicle garages need thicker slabs and stronger reinforcement than typical residential floors. A typical RV bay pour ranges from 5 to 6 inches of concrete with rebar reinforcement sized for the vehicle weight. During the estimate, we review the specific vehicles you plan to store and design the floor to handle them safely for years.

Concrete garage floors crack or heave for a handful of common reasons. Poor base preparation is the biggest cause. If the subgrade is not compacted properly, the concrete moves and cracks under vehicle weight. Other causes include the wrong slab thickness for the load, missing or insufficient reinforcement, poor drainage that erodes the base under the floor, and freeze-thaw cycles that expand and contract the concrete. Small hairline cracks are normal, but structural cracking usually points to one of these underlying issues.

Yes. New construction garage floor pours are a regular part of our work. We coordinate with your builder or general contractor on timing, footprint, drainage, and reinforcement so the pour fits the overall build schedule. Whether you are adding a garage to an existing home, building a detached workshop, or pouring a floor for a new construction house, we handle the slab work.

Foot traffic on a new garage floor is usually fine after 24 to 48 hours. Passenger vehicles can typically use the floor after 5 to 7 days of curing. Heavy vehicles, RVs, trailers, or delivery trucks should wait a full 28 days for the concrete to reach full curing strength. We share specific curing timelines with you during the final walkthrough so you know exactly when different types of use are safe.

Yes. Pouring a garage floor around existing walls, footings, drains, or utility connections is a normal part of most garage projects. We form around the existing structures, plan expansion joints in the right places, and pour the slab to fit the space. In renovation and conversion projects, this kind of work is standard, and we handle it as part of the full pour.
