Foundation Contractor in Northeast Oklahoma
Slab Foundations, Pier and Beam, Structural Repairs
Everything you build sits on the foundation. If it’s wrong, nothing above it matters. Shea Construction handles foundation work for new construction and existing homes across the Green Country region. We pour slabs, build pier and beam systems, repair settling foundations, and re-level structures that have shifted on Oklahoma’s clay soil.
Foundation Work for Northeast Oklahoma Homes and Buildings
Oklahoma sits on some of the most challenging soil in the country for residential and commercial foundations. Expansive clay soils throughout Northeast Oklahoma swell when they absorb moisture and shrink when they dry out. This seasonal cycle puts constant pressure on foundations, causing settling, cracking, heaving, and structural movement over time. It’s one of the main reasons foundation problems are so common in the Tulsa metro, Mayes County, Rogers County, and the surrounding Green Country region.
Â
Shea Construction handles foundation work across two categories: new construction foundations for custom homes, barndominiums, metal buildings, additions, and commercial projects, and structural repair for existing homes with settling, cracking, or leveling issues. We serve more than 30 cities across Northeast Oklahoma and work with licensed structural engineers when needed to ensure every foundation is designed for the specific soil conditions and load requirements on your property.

For new construction projects, the foundation is designed as part of our 3D visualization and blueprint process. You see the foundation plan as part of the overall build design before we pour a single yard of concrete.
Signs Your Foundation Needs Attention
Cracks in Interior Walls or Around Windows
Diagonal cracks that start at the corners of windows and doors are one of the most common signs of foundation movement. Hairline cracks can be cosmetic, but cracks wider than 1/8 of an inch or cracks that are growing over time warrant a professional assessment.
Doors and Windows That Won't Open or Close Properly
When a foundation shifts, the frame of the house moves with it. Doors that stick, won’t latch, or have gaps along the frame are often caused by uneven settling rather than a problem with the door itself. The same applies to windows that bind or won’t lock.
Uneven or Sloping Floors
If you can feel the floor dipping in one direction, or if a ball rolls on its own when set down, the foundation has likely settled unevenly. This is especially common in homes on pier and beam foundations, where individual piers can shift independently.
Gaps Between Walls and Ceiling or Walls and Floor
Visible separation where walls meet the ceiling, floor, or other walls indicates structural movement. These gaps tend to widen over time if the underlying foundation issue isn’t addressed. In pier and beam homes, this often means one or more support piers have settled or deteriorated.
Exterior Cracks in the Foundation or Brick
Stair-step cracks in exterior brick, horizontal cracks in the concrete slab, or vertical cracks in the perimeter foundation wall all point to movement beneath the structure. Oklahoma’s clay soil cycle of swell and shrink is the most common cause in this region.
Types of Foundation Services We Provide
Concrete slab foundations poured for custom homes, barndominiums, metal buildings, and commercial structures. Slab thickness, reinforcement, and site preparation are engineered for the building’s size, load, and the soil conditions on your specific lot. In Oklahoma, new slab foundations for residential construction typically cost $25,000 to $50,000, depending on the home’s footprint and site requirements.
Post-supported foundation systems for new construction and additions where slab-on-grade isn’t the right fit. Pier and beam foundations elevate the structure above grade, creating a crawl space for access to plumbing and utilities. This foundation type is common in older Northeast Oklahoma homes and is sometimes required by site conditions such as flood zones, steep grades, or highly expansive soil.
Structural repair for existing homes and buildings with settling, cracking, or shifting foundations. Foundation repair in the Tulsa metro and surrounding areas typically costs $3,000 to $15,000, depending on the severity and number of support points needed. We handle pier installation, beam replacement, joist repair, and full re-leveling for homes that have shifted on Oklahoma’s expansive clay soil.
Load-bearing wall assessment, floor joist replacement, beam reinforcement, and crawl space structural support. When the foundation shifts, the framing above it can sustain damage too. We repair both the foundation and the structural framing above it, so the problem is fully resolved, not patched over.
Benefits of Hiring a Full-Service Foundation Contractor
We Build What Goes Above and Below
Most foundation-only contractors stop at the slab. They don’t build the house on top of it. Shea Construction handles the entire project, from the foundation through framing, mechanical systems, and interior finish. That means the foundation is designed for the specific structure going on it, not poured as a standalone job disconnected from the build plan.
We Know Oklahoma's Soil
Expansive clay is the defining challenge for foundations in Northeast Oklahoma. Soil conditions vary by county and even by lot. We assess the site before design begins and specify the foundation type, depth, reinforcement, and drainage based on what the soil actually requires. We’ve worked across Mayes, Rogers, Cherokee, Tulsa, Wagoner, Muskogee, and surrounding counties.
We Handle Repair and New Construction Under One Roof
If your foundation issue is part of a larger project, like a home addition that needs the existing foundation reinforced, or a storm-damaged home that needs structural and foundation work, we coordinate everything. You don’t need to hire a separate foundation company and then a separate contractor for the rest.
Structural Engineering and Licensed Trades
Foundation work that involves structural modifications, load-bearing changes, or significant repair typically requires a structural engineer’s assessment. We coordinate with licensed structural engineers when needed and use only licensed and insured subcontractors for all concrete, reinforcement, and mechanical work tied to the foundation scope.
What Foundation Work Includes
The scope depends on whether this is a new construction foundation or a repair/leveling project. Here’s what each involves:
Site evaluation and soil assessment. Excavation and grading. Form setting, rebar and wire mesh placement, and concrete pour. Anchor bolt installation for framing attachment. Curing time and inspection. The foundation is designed as part of the overall build blueprint, ensuring it’s sized and reinforced for the specific structure going on top of it.
Pier placement at engineered intervals. Beam installation spanning between piers. Floor joist framing on top of beams. Crawl space access and ventilation planning. This system is used for new builds where slab-on-grade isn’t appropriate and for additions that need to match an existing pier and beam structure.
On-site assessment of the damage, including interior and exterior crack mapping and floor-level measurement. Structural engineer consultation if needed. Pier installation (steel push piers or helical piers) at calculated intervals along the affected area. Beam and joist repair or replacement in pier and beam homes. Re-leveling of the structure to restore even floor planes. Crack sealing and cosmetic repair of affected surfaces.
All permitting and required inspections are managed by our team. Foundation work is backed by our 1-year warranty on workmanship. Pier systems installed may carry additional manufacturer warranties.
Related Services
Every custom home starts with the right foundation. We design the foundation as part of the full 3D build plan, ensuring it’s engineered for your floor plan, your lot, and Oklahoma’s soil conditions.
Home additions require a new foundation section that ties into your existing structure. We pour and connect the new foundation as part of the full addition build.
Foundation movement often causes secondary damage to drywall, doors, windows, and trim throughout the home. We can handle the structural repair and the cosmetic repair together.

Foundation Questions
How much does a new foundation cost in Oklahoma?
New slab foundations for residential construction typically cost $25,000 to $50,000, depending on the home’s size, slab thickness, reinforcement requirements, and soil conditions. Pier and beam foundations can fall in a similar range. We provide a detailed foundation quote as part of the overall project design.
How much does foundation repair cost?
Foundation repair in Northeast Oklahoma typically ranges from $3,000 to $15,000, with more extensive repairs costing $15,000 to $30,000 or more if a large number of piers are required. The cost depends on the severity of the damage, the foundation type, and site accessibility. We assess the property and provide a clear scope and quote before any work begins.
Why are foundation problems so common in Oklahoma?
Oklahoma’s expansive clay soils are the primary cause. These soils swell significantly when they absorb moisture during rain and shrink when they dry out during summer heat. This repeated cycle puts constant lateral and vertical pressure on foundations, causing settlement, heaving, and cracking over time. Proper foundation design and drainage are the best defenses against this.
How do I know if I need a structural engineer?
If you have significant foundation cracking, visible structural movement, walls pulling away from the ceiling or floor, or floors sloping more than 1 inch over 10 feet, a structural engineer’s assessment is recommended. A structural engineer in Oklahoma typically charges $750 to $1,500 for an inspection and report. We can coordinate this as part of your project.
Do you handle foundation work for additions and remodels?
Yes. Every home addition requires a new foundation section tied into the existing structure, and some remodels involve load-bearing wall changes that affect the foundation. We handle foundation work as part of the overall project scope for additions, remodels, and restoration projects.
