Exterior Restoration

Exterior Restoration is a specialized area of architectural and engineering practice that focuses on the repair and replacement of various elements of the exterior envelope of a building. The exterior envelope of a building includes everything that separates the interior of a building from the outdoor environment.

HLZA has extensive experience in the investigation and renovation of building envelopes and structural systems dating from the 1800's to the present. These building assemblies, which consist of numerous integrated components, vary greatly in terms of materials and degree of technical complexity. Additionally, these systems must all be designed to withstand the forces of the exterior environment such as thermal expansion, freeze-thaw cycles, solar heat gain, ultraviolet degradation, atmospheric pollutants, seismic and wind forces, as well as seasonal rain and snow.

Our knowledgeable and professional staff can manage the comprehensive requirements necessary to restore function and performance of the building envelope.
