Siding & exteriors
Seal the envelope, stop the water damage.
Failing siding and trim are how water gets into the structure — and how small repairs turn into major reserve expenses. OSSA restores the full exterior envelope so your buildings stay dry, uniform, and protected.

What we handle
The full exterior envelope.
From a few failing panels to a community-wide re-siding program, we keep the whole exterior consistent and watertight.
Trim & Fascia Restoration
Architectural trim, fascia, and column wraps restored or replaced to keep the original look intact.
Waterproofing & Flashing
Proper flashing, sealing, and weather barriers detailed so water stays out of the structure.
Wood-Rot Remediation
We open up suspect areas, remove rot, and rebuild with treated materials before re-cladding.
Gutters, Soffit & Fascia
Repair and replacement of gutters, soffit, and fascia that manage water away from the building.
Industrial Power Washing
Scheduled, building-safe power washing of exteriors, walkways, and shared concrete year-round.
