What We Do
Building-envelope expertise
Siding
Commercial wall cladding and siding repair or replacement that ties cleanly into windows, roofs, and waterproofing details.
Windows
Window replacement and perimeter detailing that keep the opening weathertight and aligned with the rest of the envelope.
Waterproofing
Above- and below-grade waterproofing for foundations, walls, plazas, and decks, tracing moisture back to its real entry point.
Sheet Metal
Copings, counterflashing, gutters, and custom-fabricated details that move water safely away from the building.
Stone and Masonry
Brick, block, and stone repair and repointing that restores both structural function and finished appearance.
Restoration in Action
Deteriorated facade, fully restored.
Cracked mortar and failing flashing rebuilt to protect the building — the kind of envelope restoration GD Osman plans as one coordinated scope.
