Olshan Foundation Repair in Oklahoma City: Basement and Crawlspace Waterproofing for Clay Soil Homes
Olshan Foundation Repair is a regional foundation contractor serving Oklahoma City and surrounding areas, specializing in waterproofing, crawlspace encapsulation, and structural repairs for homes built on the clay-heavy soil common to central Oklahoma. The company operates as a full-service foundation specialist rather than a general contractor taking foundation work as one of many services.
What Olshan Actually Is
Olshan is a foundation-focused contractor, not a general handyman or multi-trade shop. The business handles below-grade water intrusion, crawlspace moisture, basement wall cracks, and settling issues specific to Oklahoma's soil conditions. Most calls come from homeowners dealing with water in basements during spring rains or from those recognizing crawlspace moisture before it becomes structural rot. The company also handles concrete leveling and slab work. It does not do roofing, siding, or interior renovation; those jobs get referred elsewhere.
Services and Pricing
Olshan offers crawlspace encapsulation (vapor barrier installation with dehumidification), interior and exterior waterproofing systems, sump pump installation, wall stabilization, and concrete lifting. A crawlspace encapsulation runs $3,000 to $8,000 depending on square footage and soil conditions. Interior waterproofing with a perimeter drain system typically ranges $4,000 to $10,000. Exterior waterproofing (foundation coating and grading work) costs $2,500 to $6,000. Sump pump installation alone runs $1,500 to $3,000 with a backup battery system adding $800 to $1,200. All estimates are free and include a property inspection. Pricing varies by the specifics of clay content, water table depth, and existing damage; confirm current rates directly before committing.
How Olshan Compares to Other Oklahoma City Foundation Contractors
Oklahoma City has several foundation specialists. Olshan competes most directly with Foundation Professionals USA and Basement Systems of Oklahoma. Foundation Professionals USA emphasizes pier-and-beam repair and can handle more severe settling cases; choose them if your home shows visible foundation tilt or major structural movement. Basement Systems of Oklahoma focuses on waterproofing and crawlspace encapsulation and uses similar methods to Olshan but tends to quote higher for labor-intensive exterior work. Choose Olshan when you want a straightforward waterproofing job (interior or crawlspace) and cost is a primary concern; choose Foundation Professionals USA if settling is the main issue; choose Basement Systems if you prefer a larger regional brand and don't mind premium pricing.
Who It Suits and Who It Does Not
Olshan works best for homeowners with wet basements, musty crawlspaces, or visible wall cracking who have owned their home for at least a few years and want to prevent further damage. It suits budget-conscious owners willing to accept interior solutions (sump pump and interior drain) instead of exterior excavation. It does not suit homeowners needing emergency 24-hour service; Olshan operates on business hours. It is also not the right choice if your foundation shows severe tilting, major vertical cracks wider than 1/4 inch, or doors and windows that no longer close properly; those cases need structural engineers and more intensive pier work than Olshan typically handles.
What the First Visit Involves
Call or request an estimate through the website. An inspector will arrive, walk the basement or crawlspace, measure it, probe the soil, check for active seepage, and assess drainage around the exterior. The visit takes 45 minutes to an hour. You receive a written estimate on-site or within one business day. If you approve, scheduling for installation typically happens within 2 to 4 weeks depending on season; spring sees longer waits because heavy rains spike demand.
Hours, Parking, and Logistics
Olshan operates Monday through Friday, 8 a.m. to 5 p.m., with Saturday appointments available by request during peak season. The company dispatches crews to job sites; you do not visit an office. Work crews typically complete crawlspace encapsulation or interior waterproofing in one to three days depending on square footage and system complexity. Exterior work may take longer and often requires some yard disruption.
Olshan's regional focus and clay-soil expertise make it a practical first call for the majority of Oklahoma City homeowners facing water or moisture below grade.
