Local expertise
Why Ronkonkoma masonry has to be built right.
Ronkonkoma straddles multiple townships and sits around the lake that gives it its name — a busy corridor with a large commuter population thanks to the LIRR station and MacArthur Airport nearby. Housing is mostly 1960s–1980s split-levels, ranches, and colonials, with newer builds sprinkled in. We do a lot of full-driveway replacements here (the older asphalt is well past its lifespan), plus paver walkways, front stoops, and modest patio builds. Lakeside lots occasionally need retaining walls for the grade change down to the water.
Central Suffolk sits inland on deep glacial sand. It drains well, but winters swing hard through freeze and thaw, and any footing poured above the 42-inch frost line will heave a stoop or wall out of level within a few seasons.
Most Brookhaven streets are 1950s–80s capes, ranches and high-ranches. The masonry we rebuild most often is the original poured or block front stoop, settled brick walkways, and short landscape walls holding sloped front yards along the Route 112 and LIE corridors.
Failed stoops here almost always trace back to shallow footings or missing drainage behind a wall. We dig to frost depth, install clean stone and weep drainage, and reinforce every step so it stays put.
Most of Ronkonkoma is Town of Brookhaven; parts fall under Islip. We pull permits from whichever applies. Soils near the lake can hold water — drainage tile behind retaining walls is standard on any lakeside job.
