O'Shea Custom Contracting in Baltimore: General Contractor for Residential Renovations and Additions
O'Shea Custom Contracting is a licensed general contractor based in Baltimore that handles residential renovations, additions, and remodels for homeowners across the city and surrounding counties. The company operates as a single-owner operation focused on kitchen and bathroom work alongside structural additions, positioning it in the mid-range of Baltimore's general contracting market where most jobs run between $30,000 and $150,000.
What O'Shea Custom Contracting actually does
O'Shea Custom Contracting holds a Maryland Home Improvement Contractor license and handles jobs that require permitting through Baltimore City and Baltimore County. The company manages the full process from initial estimate through final inspection, including permit applications, subcontractor coordination, and city compliance. This means you are not managing multiple trades yourself; one point of contact oversees electricians, plumbers, and inspectors. The business does not handle commercial work, property flips, or emergency repairs.
Services and pricing
Kitchen remodels typically range from $40,000 to $80,000 depending on cabinet selection, countertop material, and whether plumbing or electrical work is needed. Bathroom remodels run $20,000 to $50,000 for a full gut and rebuild, or $8,000 to $15,000 for cosmetic updates like tile and fixture replacement. Room additions and second-story work begin around $35,000 and scale upward based on square footage and structural complexity. Estimates are free, and O'Shea provides written project timelines and material specifications before work begins. Payment typically follows a deposit structure (often 30 percent down), draw payments as phases complete, and final payment upon inspection approval. Confirm current pricing by phone, as material costs fluctuate.
How O'Shea compares to other Baltimore general contractors
Baltimore's general contracting market divides roughly into three tiers. Small handyman-focused operations like many independent contractors price lower but handle only cosmetic work and avoid city permits. Mid-tier licensed contractors like O'Shea take on permitted projects and coordinate trades but may require longer project timelines (8 to 16 weeks for a full kitchen). Large firms with multiple crews and designer partnerships charge premium rates (20 to 30 percent above mid-tier) but complete work faster and offer in-house design consultation. O'Shea suits homeowners who need a licensed contractor with city approval but prioritize a straightforward, single-owner relationship over speed or design-forward services. If your project requires architectural drawings or design services, larger firms like those operating out of Canton or Federal Hill will include that; O'Shea works from your specifications or collaborates with an architect you hire separately.
Who O'Shea suits and who it does not
O'Shea is a fit for Baltimore homeowners doing a planned renovation (not an emergency), those comfortable with a 10 to 14-week timeline, and those who want a single licensed point of contact. The company works well for mid-budget projects where you have a clear scope and are not looking for premium finishes or fast-track scheduling. O'Shea is not the choice if you need work within 3 weeks, want an in-house designer, or are renovating a historic home requiring specialized restoration expertise (Federal Hill and Canton have contractors with that focus). The company also does not take on large commercial builds or spec homes.
What the first visit involves
Contact O'Shea by phone to request an on-site consultation. During the initial visit, the owner or project manager walks your space, takes measurements and photos, discusses your goals and budget, and asks about any structural concerns or existing permits. You will receive a written estimate within 5 to 7 business days, including a material breakdown, labor estimate, timeline, and proposed payment schedule. If you accept, you sign a contract and provide the initial deposit. Work typically begins within 2 to 4 weeks depending on the current project queue.
Hours, parking, and logistics
O'Shea operates Monday through Friday during standard business hours. Work crews are on-site during agreed-upon hours (typically 7 a.m. to 4 p.m. on residential jobs) and can accommodate earlier or later start times by arrangement. Confirm current contact information and scheduling availability directly, as these details shift seasonally.
O'Shea Custom Contracting fills a steady demand in Baltimore for licensed renovation work that does not require a large firm's overhead or timeline constraints. The company's single-owner model means consistent communication and accountability.
