G.L. Capasso Inc. was contracted to clean the exterior limestone of the LEPH façade.  Years of exposure to pollutants turned the color of the limestone façade from a light grey color to a dark grey and black color.  To successfully restore and clean the limestone surfaces, G.L. Capasso Inc. employed a number of minimally invasive treatment techniques, including hot water washes, detergent cleanings, biological (anti-microbial) cleaning, and water misting. Especially difficult surface residue was removed using low-pressure micro-air abrasion. Any surface cleaning work was first performed on sample sections before being fully applied.

In addition to the cleaning of the limestone façade, G.L. Capasso Inc. performed Dutchman repairs on the limestone and removed and replaced over six miles of caulk.  The project was completed on time and to the satisfaction of the owner and consultant.
