Facade cleaning is one of the most under-appreciated capital improvements a NYC building can make. Beyond aesthetics, it improves Local Law 11 inspection outcomes, attracts premium tenants, and extends repointing cycles by years.
TIP:NYC Local Law 11 requires facade inspections every 5 years for buildings over 6 stories. A clean facade makes inspections smoother and reveals hidden damage earlier.
