Most of the masonry we repair in Catonsville sits on a slope, and nearly all of it was built in one of two waves. The town runs along Baltimore City's western border, about 6.5 miles west of downtown: 14 square miles, population 44,701. This is Piedmont country, rolling hills and small streams, with the Patapsco River gorge forming the southern boundary at Patapsco Valley State Park. UMBC, CCBC-Catonsville and Benjamin Banneker Historical Park all sit in the same terrain. Very little ground here is flat, and that drives more repair work in 21228 than anything else.
The housing stock is bimodal: a 1940s peak of roughly 4,463 units and a 1970s peak of roughly 3,877, with a substantial older core underneath both. That core grew along Frederick Road, MD 144, as a streetcar suburb, horsecar from 1862 and electric streetcar in the 1890s. The pre-1940 stock is late-Victorian and early-twentieth-century frame and masonry: Queen Anne, Bungalow, Colonial Revival, Tudor Revival and Craftsman, plus nineteenth-century I-houses. The 1940s through 1960s brought brick Capes and ramblers, including Westview Park, about 1,800 homes built 1955 to 1967. The 1970s brought Woodbridge Valley, roughly 1,000 brick-veneer townhomes and split-levels, with College Hills, Academy Heights and Ashton Valley around them.
Three National Register historic districts sit inside those boundaries. Old Catonsville, listed in 2002, was laid out with the electric railway and includes an Art Deco water tower. Central Catonsville and Summit Park, listed in 2006, covers structures spanning 1869 to 1958, centered on "The Summit," an 1850s Second Empire summer house. Winters Lane, listed in 2007, is a historically African-American community of 155 properties built from 1867 to the mid-1940s: 141 residences, two former schools, three commercial buildings, three social clubs and five churches or church facilities.
Catonsville masonry therefore covers two problems side by side: pre-1940 stock laid in soft lime mortar, with tall exterior chimneys, corbelled brickwork, rubble stone foundations and masonry porch piers, and postwar brick and 1970s veneer on graded, terraced lots. Both need work, but not the same work, and certainly not the same mortar.
