Our Home Addition Foundation Process

Excavation & Footings

Footings are excavated to proper depth and reinforced based on structural needs and local building codes.

Forming & Reinforcement

Forms are set square and level, with rebar placed correctly to support the new structure long-term.

Concrete Pour & Final Inspection

Concrete is poured and finished cleanly, leaving the foundation ready to pass inspection so framing can begin without delays.

Built Right The First Time

A foundation is permanent. Mistakes at this stage can lead to settling, cracking, inspection issues, or costly repairs later. That’s why our focus is on doing the work correctly from the beginning — from layout and footing depth to reinforcement and concrete placement.

Before any concrete is poured, we verify elevations, depths, and layout to ensure everything is built as intended. This level of oversight helps ensure your home addition foundation supports the structure long-term and passes inspection without surprises.

Frequently Asked Questions

It depends on the size and complexity of the project, but most residential foundations take about 1 to 2 weeks from excavation to finished concrete — weather permitting. Since we only take one foundation project at a time, we keep your schedule tight and delays minimal.

Yes. We’re licensed contractors and have relationships with local municipalities throughout the Kansas City area, which helps us speed up the permitting and inspection process. We’ll coordinate everything so you don’t have to.

Yes — our work includes a 1-year workmanship warranty for your peace of mind.

Yes, we specialize in flatwork and slab pours. If your project includes a basement, garage, and driveway, we can take care of the entire package — and often offer a discount when we handle all the concrete work together.

We use our own excavator, Bobcat, and dump truck. This means we don’t rely on outside crews or rentals, so we can control quality and schedule — and make sure the site is graded and leveled properly before any concrete is poured.

We work with both. Whether you're a general contractor managing a full build or a homeowner doing an addition or new garage, we’ll walk you through the process, answer your questions, and handle our part of the job with professionalism and care. Keep in mind: a new foundation isn’t a $10,000 project. The additions shown above averaged $50–$60K, and even small one-room additions can cost $15–$25K just for the concrete work. We’re upfront about pricing so there are no surprises, and we can often give a ballpark cost based on square footage.

No — we specialize in flatwork and take care of all slab pours ourselves. That means one crew, one schedule, and no miscommunication between trades. If you're building walls or a structure on top, we’ll leave everything level, square, and ready to go.

Costs vary based on site conditions, thickness, type of foundation (basement vs. slab), and whether you need additional excavation or haul-off. However, we’re happy to give you a ballpark price based on square footage, or come out for a full estimate.

We use laser levels and string-line systems to ensure every pour is accurate and square. Our background in framing gives us a builder’s eye for precision — so you don’t run into problems later when it’s time to build on top.
