Why seal in South City
Concrete that stays wet grows moss and algae and stains easily. A breathable penetrating sealer reduces water absorption without trapping moisture.
What we seal
Driveways, front steps, walkways, patios and loading areas.
Our process
We clean, treat organic stains, let the concrete dry and apply sealer.
Will it stop moss?
It slows growth; regular cleaning still helps.
How often should I reseal?
Every few years.
Steep front steps on the west side
Homes in neighborhoods like Westborough often have long runs of concrete steps up to the front door. Those steps stay damp in the fog and can turn green and slick. We clean them thoroughly, let them dry, then apply a sealer that keeps the natural texture so the steps stay grippy. A light grit can be added to topical sealers if needed.
Loading areas and drive aprons
Commercial aprons near the airport see heavy trucks and oil drips. Sealing helps keep fluids on the surface for cleanup.
