Building Envelope Restoration

Buildings require restoration and remedial services for a number of reasons. Age, environmental factors, poor construction or design can all be reasons that a building (or a parking garage) would require remedial services. We have the expertise to provide a full range of restoration services regardless if your building is relatively new or a historic structure. These services include sealant removal and replacement, brick replacement and pointing, wet glazing, cleaning, sealing, remedial waterproofing, removal and replacement of expansion joint assemblies, wet glazing, flashing repair, deck coatings, façade stabilization and many other remedial services and investigations. When on a restoration project, we work closely with the design team and building owners to restore the building back to its intended purpose.
