Our Middletown shop contains facilities and equipment for lead and asbestos abatement, for which we are certified. Separate rooms for steaming/stripping, and sanding allow us to process large jobs and maintain productivity and cleanliness. We use two high efficiency Steam Stripper ovens made by Bagala to harmlessly loosen years of paint and glazing from old windows and doors. For objects which are larger or sensitive to steam, we employ different intensities of chemical strippers, heat guns, and UV lamps. Various Syclone Mk4 HEPA filters keep clean air circulating in the contamination area. KSR additionally has many years of experience in dealing with abatement on site, keeping with current OSHA regulations to isolate and remove lead and asbestos even in currently occupied buildings and areas near pedestrian use. Contractors choose KSR first when confronted with historic resources affected by these hazardous materials, due to our attention to hygiene illustrated by our extensive list of safety awards.

Kronenberger & Sons has years of experience overseeing the planning, design, and construction of projects both large and small. Our clients have included anyone from the federal government to the average homeowner. For as long as we have been construction managers, we have specialized the preservation of historical buildings. In our later years, we have acted as historic consultants, utilizing our extensive knowledge on old structures to help partners and other contractors when they seek advice. We are proud to have a Registered Historical Architect on our team who meets the Secretary of The Interior Professional Qualification Standards.
