Adding Construction in Baltimore: Concrete and Masonry for New Builds and Structural Repairs

Adding Construction is a licensed masonry and concrete contractor serving Baltimore and surrounding counties, specializing in foundation work, structural concrete, and decorative masonry for residential and light commercial projects. The company operates as a full-service operation, meaning they handle design consultation, permitting, execution, and warranty follow-up without subcontracting the core work, which is uncommon in a market where many Baltimore contractors manage crews rather than employ them in-house.

What Adding Construction Actually Does

Adding Construction focuses on concrete flatwork (driveways, patios, and slabs), foundation repair and new installation, brick and stone masonry, and retaining walls. They take on jobs ranging from 500-square-foot residential driveway replacements to multi-unit commercial foundation projects. The company is licensed by the State of Maryland and carries both general liability and workers' compensation insurance, a baseline requirement that not all small masonry operations in Baltimore maintain transparently. They also pull permits on behalf of clients, a detail that matters because unpermitted concrete work in Baltimore can trigger city code violations and complications if a property changes hands.

Services and Pricing

Concrete work pricing runs roughly $8 to $14 per square foot for standard driveway or patio work, depending on thickness, site access, and removal of existing material. A typical 500-square-foot driveway replacement in Baltimore averages $4,500 to $7,000 installed. Foundation repairs and new pours cost significantly more and are quoted per project because variables like soil testing, depth, and reinforcement requirements vary. Masonry work for new chimneys, walls, or repairs ranges from $20 to $40 per square foot of finished surface, again dependent on materials (standard brick versus specialty stone) and complexity.

Adding Construction offers estimates at no charge and typically provides a written proposal within three business days of a site visit. They do not require a deposit to begin most residential jobs, though customers should confirm current payment terms directly, as terms can shift with material costs.

How Adding Construction Compares to Other Baltimore Masonry and Concrete Contractors

Baltimore's masonry market splits into two tiers: large commercial firms with crews of 20 or more, and small owner-operator shops working one to three jobs at a time. Adding Construction sits in the middle, with five permanent employees and the flexibility to absorb residential projects without the overhead markup of larger firms. By comparison, companies like Concrete Contractors of Baltimore (a commercial-focused outfit) typically handle projects starting at $25,000 and work primarily with developers; their smaller residential work often takes lower priority. At the other end, independent masons operating from home workshops can undercut Adding Construction's pricing by 15 to 20 percent but frequently lack bonding and may not pull permits, exposing owners to risk.

Adding Construction's advantage is consistency: the same crew handles your project from pour to finish, reducing miscommunication and quality drift. A smaller solo contractor may offer a lower bid but may not return if a problem arises six months later, whereas Adding Construction's licensing and liability insurance create accountability.

Who This Suits and Who It Does Not

Adding Construction is the right choice for Baltimore homeowners replacing a driveway, repairing a foundation, or adding a new patio, especially if permit compliance and warranty backing matter. It also suits small commercial clients and property managers who need reliable, licensed work without a commercial-scale price tag. It is not well-suited for emergency 24-hour concrete repair or for ultra-premium decorative stone work requiring architectural oversight, though they can recommend specialists for those needs.

What the First Visit Involves

Call to schedule a site visit; Adding Construction typically arrives within five to seven business days. The owner or a senior crew member will assess the project, take measurements, ask about your timeline and material preferences, and identify any complicating factors (poor drainage, existing utilities, soil conditions). They will discuss permit requirements if applicable. A written estimate follows, usually within three days, with a start date contingent on weather and material availability. Concrete work is weather-dependent; the company does not pour when temperatures drop below 50 degrees Fahrenheit.

Hours, Parking, and Logistics

Adding Construction operates Monday through Friday, 7 a.m. to 4 p.m., with limited Saturday availability for residential jobs. They are based in Dundalk and serve Baltimore city and Baltimore, Anne Arundel, and Howard counties. Work crews arrive early and depart by late afternoon; site preparation and cleanup are included in quoted prices. Confirm current scheduling before booking, as seasonal demand can extend wait times by two to four weeks in spring and early summer.

Adding Construction fills a gap between the discount contractor and the large firm, offering licensed, bonded work with real accountability in a city where both shoddy DIY patches and unnecessary overcharges remain common.
