We handle permits and required inspections and build from a stamped plan engineered for the site. Ryan Cartwright is an ICC-certified General Building Contractor, Class A, and KCMO Residential Building Supervisor. Cartwright Construction is licensed in Kansas City and Liberty and insured.
New Cartwright construction agreements include a 10-year limited warranty for our workmanship and structural work within the signed scope, starting at substantial completion. Manufacturer warranties apply separately. Contact Cartwright directly for covered service.
We confirm the plan, selections, and site conditions, then put the complete fixed price, approved add-ons, deposit, and milestones in the contract before construction.
Many buyers use a construction loan. After the plan, site, and scope are confirmed, we provide the contract, specifications, and draw schedule. Financing terms and approval come from your lender.
Fifteen years of carpentry, trim, stonework, and high-end remodeling shape our workmanship standard. Plans, finishes, allowances, and exclusions are documented before construction. See our finish work →
