Alonso Construction Services in Baltimore: General Contractor for Residential Renovations and Additions

Alonso Construction Services is a licensed general contractor operating in Baltimore that handles residential renovation projects, kitchen and bathroom remodels, and home additions for single-family properties and townhouses across the city. The business works directly with homeowners on projects ranging from $15,000 to $250,000, managing permitting, subcontractors, and timelines in-house rather than referring clients elsewhere.

What Alonso Construction Services actually does

The company holds a Maryland Home Improvement License and carries liability insurance, both required credentials for work in Baltimore. Most projects fall into three categories: interior remodels (kitchens, bathrooms, flooring), structural additions (second stories, sunrooms, decks), and cosmetic renovations (siding replacement, roof work, window installation). The owner meets with each client to establish scope, timeline, and budget before work begins and typically takes on one to three projects simultaneously rather than maintaining a large queue.

Services and pricing structure

Kitchen remodels in Baltimore typically run $25,000 to $60,000 depending on cabinet choice, countertop material, and appliance selection; mid-range kitchens (semi-custom cabinets, quartz or laminate counters, mid-tier appliances) cluster around $40,000. Bathroom remodels range from $12,000 for a modest update to $35,000 for a full spa-style renovation with tile work and custom cabinetry. Roof replacement costs $8,000 to $18,000 for a typical Baltimore rowhouse, with asphalt shingles at the lower end and architectural or metal roofing at the higher end. Second-story additions or sunroom builds start at $60,000 and scale with square footage and finish level.

The company quotes each project individually after a site visit and does not publish a flat hourly rate. Most estimates include materials, labor, and permits. Clients should confirm current pricing, as material costs fluctuate and labor rates shift seasonally; spring and early summer (April through June) often see higher demand and longer timelines.

How Alonso Construction compares to other Baltimore general contractors

Alonso operates at a different scale than larger firms like Structural Enterprises or Chesapeake Building Consultants, which often manage commercial work or handle multiple large projects simultaneously and may have longer lead times. Small independent contractors charging by the hour ($50 to $75 per hour) are cheaper upfront but lack the permitting oversight and insurance protection that licensed general contractors provide; the homeowner bears more risk if something goes wrong. Specialty contractors (kitchen designers, electricians, plumbers) handle one trade only and require the homeowner to coordinate between vendors. Alonso's model suits homeowners who want a single point of contact and don't have time or expertise to hire and manage separate trades.

Who should and should not choose this contractor

This contractor works best for homeowners with a defined scope, a realistic budget, and a willingness to be involved in decisions but not micromanage daily. Projects that require design input (kitchen layouts, tile selection, fixture choices) move faster when the owner is decisive. Homeowners who need a quick turnaround on emergency repairs (burst pipes, roof leaks) may find Alonso booked; he takes on renovation work primarily and does not staff 24-hour emergency service. Large-scale commercial work or spec home builds are outside his scope. First-time renovators often benefit from the guidance Alonso provides on code compliance and material durability; experienced homeowners may prefer a contractor who takes more hands-off direction.

What to expect on the first visit and beyond

The initial consultation involves a walk-through of the space, discussion of goals and budget, and a timeline estimate. Alonso takes photos and measurements, then provides a written estimate within 5 to 10 business days. Once a contract is signed, the owner secures any necessary permits (the contractor typically handles this paperwork for renovation work in Baltimore). Work begins on the agreed start date; the homeowner receives weekly updates and can request changes, though substantial scope changes may adjust the timeline and cost. Punch-list items (paint touch-ups, hardware installation, final cleaning) are completed before the final walkthrough and payment.

Hours, scheduling, and logistics

Alonso works Monday through Friday, 7:00 a.m. to 4:00 p.m., with occasional Saturday work for interior finishing tasks. The company does not maintain a physical office; initial contact is by phone or email, and meetings are scheduled at the project site or the homeowner's residence. There is no waiting period for estimates; turnaround depends on current workload. Parking during construction is arranged case-by-case; on rowhouse projects in dense neighborhoods like Canton or Fells Point, materials and equipment are staged on the street with city permits as required.

A general contractor who coordinates permits, manages subcontractors, and takes responsibility for code compliance protects homeowners from costly mistakes and delays. Alonso's client base—mostly Baltimore residents upgrading older homes in neighborhoods like Hampden, Roland Park, and Federal Hill—reflects the abundance of pre-1950s housing stock that requires experienced hands and familiarity with local building codes.
