We Started Because
Crack Injection
Was a Lie.
In 2008, Sal Benedetto watched too many Long Island homeowners lose thousands to contractors selling crack injection for structural problems. So he built a company that diagnoses first, brings a PE onto staff, and uses engineered systems — not band-aids.
18 Years. 2,100+ Homes.
