Local expertise
Why Islip masonry has to be built right.
Islip (the hamlet, seat of the township) has a walkable village core of older colonials, historic brick storefronts, and a mix of postwar and newer residential streets around it. Our masonry work in Islip includes chimney rebuilds, brick repointing on older village homes, stoop rebuilds, stone-veneer front entrances, and fieldstone retaining walls on the sloped lots north of Main Street.
South Shore Islip neighborhoods sit close to the Great South Bay with high water tables, salt air and heavy coastal storms. Water that sits behind a wall or under a step is the number one enemy of masonry here.
Expect post-war ranches, expanded capes and a lot of post-Sandy raised homes. Raised homes mean taller entry stairs and landings, which we build with poured footings, block cores and stone or paver treads.
Salt and constant moisture eat through weak mortar fast. We use air-entrained concrete, polymer-modified mortar and sealed caps so stoops, piers and walls survive the bay climate.
Islip is the seat of Town of Islip — permits and inspections are handled at the town building department directly. Older village-core homes often need repointing and crown seal work rather than full rebuilds; we'll say honestly which one you need on-site.
