Martinez Construction in Baltimore: General Contracting for Residential Renovations and Additions

Martinez Construction is a locally-operated general contracting firm that handles residential renovation projects, room additions, and structural work across Baltimore and surrounding counties. The company manages mid-to-large scope jobs that require permitting, licensed subcontractors, and coordination across multiple trades, positioning it alongside other established Baltimore general contractors rather than handymen or one-person operations.

What Martinez Construction actually does

Martinez Construction operates as a full-service general contractor, meaning the company pulls permits, coordinates subs (electricians, plumbers, HVAC technicians), and manages the job timeline from start to finish. The firm handles kitchen and bathroom remodels, second-story additions, basement finishing, structural repairs, and whole-home renovations. It is Maryland-licensed and insured. Jobs typically range from $30,000 to $300,000+, reflecting the scale at which general contracting differs from handyman work: you hire Martinez to manage the whole project, not just one trade.

Services and pricing structure

Martinez Construction works on a time-and-materials or fixed-bid basis depending on project scope and certainty. Fixed-bid estimates are provided after an in-home consultation and are typically valid for 14 days. Time-and-materials contracts (used when scope is uncertain mid-project) charge labor at a rate that varies by trade and trade experience, plus material cost and a markup. The company requires a 50% deposit to start work and the balance upon completion. Payment terms and specific labor rates should be confirmed directly, as they shift with material costs and scheduling demand.

The firm does not offer itemized service menus like plumbers or electricians do. Instead, you describe your project during a consultation, and Martinez provides a custom estimate. This model suits complex or multi-phase projects but requires more initial conversation than calling a single-trade specialist.

How Martinez Construction compares to other Baltimore general contractors

Baltimore has several established general contracting operations at similar scale. Chassix Construction and Harbor Renovations both handle full-scope residential work in the city and are similarly licensed and insured. The meaningful differences lie in responsiveness, availability, and specialization. Martinez has stronger availability for mid-size projects (under $150,000) without the longer lead times some larger firms require. Harbor Renovations and Chassix tend to prioritize larger commercial-adjacent projects. For a $40,000 kitchen remodel or $60,000 addition, Martinez typically moves faster; for a $500,000+ whole-home gut, Chassix and Harbor Renovations have deeper crew depth.

Choose Martinez for mid-range residential work in Baltimore proper and inner suburbs; choose Chassix or Harbor if your budget exceeds $200,000 or the project is in the far suburbs where those firms have established supply chains.

Who Martinez Construction suits and who it does not

This contractor works best for homeowners with a clear scope (not exploratory gut jobs where walls are opened and decisions made live), a budget between $30,000 and $200,000, and a timeline of 6 to 16 weeks. It suits people who want to work with a single point of contact rather than hiring and coordinating five separate trades themselves. It does not suit owners who need emergency same-day repairs (call a plumber or electrician directly) or those expecting work to start within a week of first contact.

What the first visit involves

Call or email Martinez Construction to request an estimate. A project manager visits your home, photographs the space, takes measurements, and discusses your scope, timeline, and budget. You walk through the space together. The manager asks whether permits are needed (required for most structural work, electrical panel changes, and HVAC replacements in Baltimore). Estimates are sent within 5 to 7 business days and include a line-item breakdown, timeline, and assumptions about existing conditions. If the estimate depends on conditions revealed mid-project (hidden rot, asbestos tile, shifted framing), that is flagged in writing.

Hours, location, and logistics

Martinez Construction operates Monday through Friday, 7:00 a.m. to 4:00 p.m., with a main office in Baltimore County. The firm services Baltimore City and Baltimore, Howard, and Anne Arundel counties. Work crews typically arrive by 7:30 a.m. and work until 4:00 p.m. on weekdays; weekend work is available at premium rates and is scheduled in advance. Parking at your home should accommodate one work truck and crew vehicles; the company will confirm space during the initial walkthrough.

Martinez Construction maintains its position in Baltimore's general contractor landscape by handling the middle-market projects that larger firms deprioritize and smaller handymen cannot legally undertake, with permitting and multi-trade coordination handled start to finish.
