K-O Construction in Baltimore: Residential Remodeling and Additions for Rowhouses
K-O Construction is a licensed general contractor specializing in interior and exterior renovation work for Baltimore's rowhouse stock, with an emphasis on kitchen and bathroom remodels, structural repairs, and second-story additions.
What K-O Construction actually is
K-O Construction operates as a residential general contractor holding a Maryland Home Improvement License. The firm focuses on projects ranging from $15,000 single-room renovations to six-figure whole-house remodels, with particular expertise in the dimensional and structural constraints of Baltimore's 19th-century rowhouses. The company manages permitting, inspections, and coordination with subcontractors in-house rather than referring clients elsewhere for municipal compliance work.
Services and pricing
Kitchen remodels start at $35,000 for a layout-preserving update with new cabinetry, countertops, and appliances, scaling to $60,000 and beyond for designs that relocate plumbing or remove walls. Bathroom renovations range from $12,000 for a standard tile-and-fixture refresh to $25,000 when moving drains or expanding square footage. Structural work including foundation repair, joist replacement, and roof work is quoted individually after inspection; these jobs often qualify for permit expediting if the contractor can demonstrate the work addresses code violations or imminent safety concerns.
The firm charges a project fee rather than hourly labor rates, meaning the client receives a fixed price before work begins. A site visit and initial estimate are free. The company requires 50 percent deposit to order materials and begin work, with the balance due upon completion and final city inspection sign-off.
How K-O Construction compares to other Baltimore options
Baltimore's general contracting market divides between large firms (Smirl & Associates, Bay Contractors) that handle commercial work and high-end residential projects above $200,000, and solo operators or small crews offering flexibility but less accountability on timeline and warranty. K-O Construction sits between these tiers: experienced enough to manage city permits and structural issues independently, but sized to give individual projects attention that larger firms reserve for their premium clients.
Choose K-O if you are remodeling a rowhouse and need someone fluent in the specific challenges of narrow lots, shared walls, and century-old framing. Choose a larger firm if your project exceeds $150,000 and you prefer a dedicated project manager on-site daily. Choose a solo contractor if your budget is under $10,000 and you can tolerate longer timelines and informal warranties.
Who K-O Construction suits and does not suit
K-O works best for homeowners in Canton, Fells Point, Federal Hill, and similar dense rowhouse neighborhoods undertaking kitchens, bathrooms, or structural work where code compliance and historic-district approval matter. The firm is equipped to handle the permit variance process and to explain why a Baltimore rowhouse cannot accommodate certain designs without additional expense.
K-O is not suited to quick cosmetic jobs (painting, flooring alone) that do not require permits or to clients who need work completed within three weeks. Typical project duration is 8 to 14 weeks depending on scope and city inspection scheduling. The firm does not do general maintenance or handyman-level repairs; it takes on renovation work where the end product is substantially different from the starting condition.
What the first visit involves
A prospective client calls or emails with project photos and a description. K-O schedules a one-hour site visit during which the owner or estimator measures the space, notes structural conditions, and discusses the scope and timeline. The estimate arrives within one week and includes a line-item material list, labor allocation by trade, and a start date. No surprises are added once work begins unless the homeowner requests a change order; structural discoveries (rot, undersized beams) are photographed and discussed with the client before proceeding.
Hours, parking, and logistics
K-O operates Monday through Friday, 7 a.m. to 4 p.m., with work crews typically on-site between 7:30 a.m. and 3:30 p.m. The company does not perform weekend work. Crews park on the street in front of the home during active work; for rowhouse projects in permit-restricted blocks, K-O applies for temporary contractor parking on behalf of the client. Contact the office to schedule estimates or discuss projects that may require evening or weekend coordination.
K-O Construction handles the permits and inspections that intimidate many Baltimore homeowners, delivering finished work that passes city sign-off without rework. For rowhouse owners in neighborhoods where every renovation touches code or historic-district rules, that in-house expertise justifies its place in a crowded contractor market.
