In Troy, the surfaces underfoot are a mix you don't see in most of the Capital Region. It's not just poured concrete drives — it's brick sidewalks in front of Washington Park, bluestone stoops on 19th-century rowhouses, brick walkways in the Pottery District, and older poured concrete aprons in South Troy and Lansingburgh. Every one of these takes a beating every winter.
Road salt gets tracked and plowed into unsealed concrete and shot straight into brick joints. Freeze/thaw cycles work water into hairline cracks, freeze it, and pop the surface loose. By spring the sidewalk out front looks tired, the stoop is streaked white with salt haze, and someone with a rented pressure wand almost always makes it worse — blown-out mortar between brick pavers or 'tiger stripes' down the driveway.
We clean Troy concrete with a commercial rotary surface cleaner for even, no-wand-mark results, and we clean historic brick and stoops at reduced pressure with masonry-safe chemistry so lime mortar joints stay intact. Sealing after cleaning is especially valuable here — Troy winters are hard and older masonry can't take too many more seasons of salt penetration.
