Kostaris Construction in Baltimore: General Contractor for Residential Renovation and New Build
Kostaris Construction is a licensed general contractor operating in Baltimore and the surrounding region, handling residential renovation, new construction, and commercial projects at scales ranging from kitchen and bathroom overhauls to full-house builds and commercial buildouts.
What Kostaris Construction actually is
Kostaris operates as a full-service general contractor, meaning they manage the entire project timeline, pull permits, hire and oversee subcontractors, and handle inspections. The firm handles both renovation and new construction work. This matters because some Baltimore contractors specialize narrowly in one category; Kostaris operates across both, which affects project flexibility if scope creeps or changes during construction. They carry appropriate licensing for Maryland and handle projects in Baltimore proper, Anne Arundel County, Howard County, and surrounding areas.
Services and typical pricing
Kostaris takes on kitchen and bathroom renovations (the most common residential project type in Baltimore), whole-house renovations, additions, basement finishing, roofing, siding, and decking work. They also manage commercial tenant fit-outs and light industrial work.
For residential renovation, general contractors in the Baltimore region typically charge $150 to $250 per hour in labor costs, or work on a time-plus-materials basis with a markup on materials (usually 15 to 25 percent). Kitchen renovations in Baltimore typically run $50,000 to $150,000 depending on finishes and scope; a bathroom refresh ranges $15,000 to $50,000. Kostaris pricing follows these regional norms. Request a written estimate for your specific scope; reputable contractors will visit the site, assess existing conditions, and itemize labor, materials, and overhead before quoting a fixed price or time-and-materials agreement. Verify current rates by contacting the firm directly, as labor and material costs shift.
How Kostaris compares to other Baltimore general contractors
Kostaris competes in a dense market. Other established Baltimore general contractors include Belair Construction, which focuses on high-end residential renovation and has a reputation for detail work and longer timelines; and Chesapeake Contracting, which leans toward commercial and larger residential projects. A third option, smaller local contractors advertising on Angie's List or Thumbtack, often charge lower hourly rates but may have less formal project management and longer scheduling delays.
Choose Kostaris if you need a contractor that handles both renovation and new construction, has established relationships with local inspectors and suppliers, and can absorb mid-project changes without shutting down. Choose a smaller contractor if budget is the primary constraint and your project is straightforward. Choose a high-end firm like Belair if finishes and design are paramount and timeline flexibility is built into your budget.
Who it suits and who it does not suit
Kostaris suits homeowners doing moderate to substantial renovations, builders planning new single-family or small multi-family projects, and commercial clients needing reliable local management. They suit clients who want a single point of contact responsible for permits, inspections, and trade coordination rather than managing subcontractors independently.
Kostaris does not suit homeowners with a very tight budget and simple scope (a single bathroom) who might save money hiring a licensed plumber and electrician directly. It does not suit clients requiring a designer or architect; Kostaris executes plans, not creates them.
What the first visit involves
Request an estimate through the firm's contact line or website. A Kostaris representative will visit your site, walk the scope with you, ask about timeline, finishes, and budget constraints, take photos and measurements, and discuss permit requirements and inspections specific to your project type. They will provide a written estimate within a typical timeframe of 5 to 10 business days. If you proceed, you sign a contract that specifies scope, pricing, timeline, change-order process, and payment schedule (usually deposits at signing and at key project milestones, with final payment on completion and inspection sign-off).
Hours, location, and logistics
Kostaris operates from a Baltimore-area office and works Monday through Friday during standard business hours for administrative and scheduling calls. Actual job sites work according to contract timelines, often starting at 7 or 8 a.m. Confirm current contact information and office location by calling or visiting their site, as business details can shift.
Kostaris Construction represents the standard Baltimore general contractor: reliable for medium-to-large residential and commercial projects where permit compliance, multi-trade coordination, and timeline accountability matter more than cutting costs or pursuing bespoke design.
