Cleaning and waterproofing two Charlotte hotels at once
Heavy biological staining on two downtown hotels, cleaned and waterproofed over three months without disrupting guests or neighbours.
In September 2015 Presto completed an extensive cleaning and waterproofing project for the Hampton and Hilton hotels in downtown Charlotte, North Carolina.
Biological staining, and nowhere to put the equipment
The exteriors of both buildings carried heavy biological staining, including along the many ledges. The job ran alongside interior renovations, and the loading areas were tight enough that every delivery and set-up had to be coordinated in advance.
There was a second constraint. Residential towers sit between the two hotels, so homeowners’ cars and personal property had to be stored and protected throughout, to keep product residue off them.
What was used
Stone Restore CB2, which is designed to remove heavy biological staining, was applied across both buildings’ entire exteriors and ledges.
Dow Corning silicone caulking was installed at the window perimeters and control joints on both properties. Years of water penetration had damaged the exterior insulation and finishing system, so patching and waterproof coatings were applied in several areas and matched to the existing facade.
Three months, two hotels, no complaints
The project ran over three months. Property management and guests were pleased with the outcome.
