J&R Structure Services in Baltimore: General Contractor for Residential Additions and Renovations
J&R Structure Services is a licensed general contractor in Baltimore specializing in residential framing, additions, and structural renovations, operating as a mid-sized firm that handles jobs from kitchen expansions to second-story builds rather than routine repairs or cosmetic work.
What J&R Structure Services actually does
The company pulls permits, manages subcontractors, and oversees the structural and framing phases of residential projects. This means they handle the skeleton of your renovation: foundation work, framing, roof structure, and the coordination required to bring plumbing, electrical, and HVAC into alignment with code. They do not offer turn-key kitchen cabinet installation or painting services, but they prepare the structural envelope so those trades can follow. Their work sits between the architect's plan and the finished space.
Services and pricing
J&R Structure Services charges a combination of labor and materials, quoted per project after an on-site estimate. A typical kitchen addition in Baltimore runs $40,000 to $85,000 depending on square footage and foundation requirements; a second-story addition ranges from $120,000 to $250,000. These figures cover framing, structural permits, temporary supports during renovation, and basic weatherproofing. Electrical rough-in, plumbing, and final finishes are usually separate line items coordinated with licensed trades. The company requires a deposit of 25 to 30 percent upfront and schedules payment in thirds: initial deposit, midpoint completion, and final walk-through. Timelines vary by scope, but a 400-square-foot addition typically takes 12 to 16 weeks from permit approval to frame completion.
How J&R Structure Services compares to other Baltimore general contractors
Baltimore's general contractor market splits into high-volume renovation firms that operate across multiple neighborhoods simultaneously and smaller owner-operated shops. J&R Structure occupies the middle ground: they take on one or two jobs at a time, which typically means more consistent communication than a large firm but longer scheduling windows than a solo contractor. For a simple kitchen refresh or bathroom remodel, a smaller handyman-level operator like those listed through the Baltimore County licensing board may cost less and move faster. For a complex addition requiring structural engineering review and coordination with utility relocation, a firm with in-house engineers (like some larger Harbor-area contractors) may reduce back-and-forth, though at higher overhead cost. J&R Structure suits homeowners who want a licensed, established firm without paying for the sales infrastructure of a regional brand.
Who it suits and who it does not suit
J&R Structure works best for homeowners planning an addition, major structural repair, or renovation that requires permits and framing work. They are a fit if you have a clear plan or an architect already on board; they will work from blueprints and coordinate with your designer. They do not suit purely cosmetic projects, emergency repairs (they do not staff emergency response), or jobs under $15,000, where the overhead of permitting and scheduling makes the economics tight. They also do not offer financing, so you need to arrange funds separately.
What the first visit involves
Contact the company by phone or through a local contractor referral network to request an estimate. They typically visit within 5 to 10 business days, walk the space with you for 45 minutes to an hour, take photos and measurements, and ask about your timeline and budget. They will flag any immediate structural concerns (rotted sills, undersized beams) that may affect cost. The written estimate arrives 3 to 5 days later and includes a line-item breakdown, a start date, and a general contract terms sheet. If you accept, you sign the contract, submit permits jointly, and pay the initial deposit before work begins.
Hours, location, and logistics
J&R Structure operates Monday through Friday, 7 a.m. to 4 p.m., with weekend site visits available by appointment. They are based in Dundalk but service Baltimore city and Baltimore County. On-site work typically runs 7 a.m. to 3:30 p.m., and crews notify neighbors in advance of any noisier activities. Parking during the job is the homeowner's responsibility; crews bring their own equipment. Permits are pulled by the company, and fees are passed through to you.
J&R Structure has sustained a license in Baltimore County for over a decade and maintains public records with the city Department of Housing and Community Development. They suit homeowners seeking a stable, permitted contractor for structural work at a reasonable middle tier.
