Services
Sealant Replacement
Got leaks? Water intrusion is more than an inconvenience for property owners and tenants. Left unchecked, it can damage structural elements and shorten the useful life of buildings, parking garages, and plaza decks.
Masonry Restoration
The materials that give masonry structures their character and beauty are vulnerable to age, moisture, pollutants, building movement, and deferred maintenance.
Parking Garage Restoration
An ineffective maintenance routine on a parking structure can quickly lead to costly repairs and restorations that can be disruptive to tenants and cause unexpected costs and safety concerns.
Waterproofing & Coatings
From below grade waterproofing to deck coatings to roof coatings, any waterproofing system is only as effective as the caliber of installation.
Concrete Restoration
Concrete is economical and durable — the backbone of modern construction. But time, water, and weather take their toll and diminish its strength.
Historical Restoration
We can restore the exterior features regardless of composition or age without damaging either the building or its historical charm.
Cobb Garage | Seattle, WA
Western Specialty Contractors’ Seattle branch completed a large concrete repair, façade restoration and waterproofing project at Cobb Garage, a parking structure located at 315 Union Street in Seattle, Washington. Serving as the prime contractor for Unico Properties, Western worked with consultant Evolution Architecture to complete the improvements ahead of a firm deadline.

The work needed to be completed before the FIFA moratorium, requiring close coordination throughout the project. With assistance from the property manager and the City of Seattle, the team expedited the permitting process and obtained a permit in two weeks. Western also faced material delays and had to coordinate stage access…
West Edge Apartments | Seattle, WA
Western Specialty Contractors’ Seattle Branch restored and waterproofed the loading dock, surrounding trash rooms and ramps at the West Edge Apartments parking garage in Seattle, WA. Facility maintenance firm Greystar hired Western in June 2025 to apply a traffic coating to the specified areas within the 39-story, mixed-use West Edge Apartments’ parking garage at 1430 2nd Ave. Western’s scope of work included surface preparation and installation of a multi-layer traffic coating system, along with routing and sealing of existing cracks using a two-part urethane sealant. Because the loading dock and surrounding areas are very busy, Western scheduled the work in two phases that allowed for foot traffic and deliveries during the project. With the tight schedule in place, Western successfully applied the traffic coating in July 2025 to enhance durability and surface protection in high-traffic areas, within budget. Maintaining a concrete parking structure can be challenging. Vehicles regularly entering parking…
