A commercial building’s exterior faces constant assault from the elements — rain, humidity, ultraviolet exposure, and biological growth like mold, algae, and mildew. Left unaddressed, these forces do more than make a property look neglected; they work into masonry and surface materials, shortening their lifespan and raising long-term maintenance costs. That was the situation facing a commercial property owner in Montclair, NJ when they called North Jersey Specialists.
A Thorough Clean Before Any Protection Is Applied
The NJS crew began with high-pressure powerwashing to remove years of accumulated dirt and surface grime. This was followed by a careful bleach cleaning treatment to eliminate biological growth and staining at the surface level. Proper preparation is not a shortcut step — it is the foundation that determines how well any protective coating will bond and perform over time. Our team takes that responsibility seriously on every commercial project we accept.
With the substrate clean and fully prepared, NJS applied a high-end siloxane sealer to the exterior masonry. Siloxane works by penetrating deep into the pores of the material rather than forming a film on top, allowing the wall to breathe while effectively repelling water infiltration. This matters especially in northern New Jersey, where repeated freeze-thaw cycles can cause serious damage to unprotected masonry over a single winter season.
What the Building Owner Gained
The transformation was immediately visible — a facade that had looked tired and weathered now looked clean, maintained, and professional. Beyond aesthetics, the siloxane sealer provides meaningful long-term protection for the building envelope, helping ownership avoid costly repairs down the road. For a commercial property in a community like Montclair, that kind of curb appeal and structural care reflects well on the business or tenants inside.
