Pacific Building Solutions is a commercial and multi-family exterior envelope remediation contractor serving the greater Seattle Metropolitan Area, including communities throughout King, Snohomish, and Pierce Counties in Washington. We hold Washington Contractor License #PACIFBS831MK and have operated across the Pacific Northwest for nearly 30 years. Our practice focuses exclusively on commercial and multifamily properties. We do not perform small residential repairs, handyman services, or single-unit work. Every project we execute is a large-scale envelope remediation, siding replacement, or capital improvement program for an HOA board, property management group, construction attorney, building envelope consultant, or commercial ownership group.

The Seattle Metro’s multi-family housing inventory was shaped by three distinct growth waves rather than one. The WWII-era Boeing manufacturing boom produced rapid, large-footprint housing developments like Renton’s wartime Highlands. The 1980s and 1990s brought a wave of garden apartment and condominium construction across Bellevue, Kirkland, and Redmond that now carries the region’s highest concentration of EIFS and exterior insulation moisture-intrusion risk, a well-documented failure pattern in pre-1996 Pacific Northwest multi-family construction. The 2000s and 2010s Amazon and tech-driven growth wave pushed apartment density into Everett, Lynnwood, and the Tacoma-Puyallup corridor. Understanding how these three distinct construction eras overlap geographically across 26 cities is not a generic capability. It is the product of nearly 30 years of executing large-scale envelope remediation programs throughout the Pacific Northwest.

• Pre-1996 EIFS and Exterior Insulation Failure Era: The 1980s and 1990s produced a wave of garden apartment and condominium construction across King County using exterior insulation and finish systems and early synthetic stucco assemblies. These systems were widely documented across the Pacific Northwest to trap moisture behind the cladding rather than shed it, and buildings from this era are now well past the point where hidden sheathing and framing damage has typically progressed.
• Tech-Driven Growth Concentrating Construction Into Narrow Windows: Microsoft’s Redmond expansion through the 1990s and Amazon’s Seattle-area growth in the 2010s each drove short, intense apartment construction booms rather than steady development over time. That concentration means large blocks of multi-family buildings across Redmond, Bellevue, and Seattle proper are now entering their first major maintenance cycle simultaneously, rather than the staggered pattern seen in slower-growing metros.
• Puget Sound Marine Climate and Sustained Wet-Season Loads: The region’s marine climate produces sustained rainfall from October through May with high humidity year-round, a load profile that accelerates any existing gap in a building’s weather barrier far faster than drier inland climates. Waterfront and lake-adjacent communities carry additional wind-driven rain exposure on top of the base wet-season load.
• Boeing and Industrial Employment Driving Historic Construction Surges: Boeing’s wartime and postwar manufacturing expansion produced rapid, large-footprint multi-family developments in south King County that established the region’s older building stock, now carrying the deepest remediation need of any era in the Seattle Metro.
• Washington Contractor Licensing: We hold Washington Contractor License #PACIFBS831MK, covering King, Snohomish, and Pierce Counties without subcontracted handoffs or regional partner gaps.

Exterior Envelope Remediation

The systematic restoration of a building’s exterior wall assembly to function as a weather-protection system. This is our primary practice across the Seattle Metro, from the region’s EIFS-era condominium stock to its aging Boeing-era apartment inventory.

Commercial Siding Replacement

Full siding replacement for multi-family properties throughout King, Snohomish, and Pierce Counties, including the exterior insulation and synthetic stucco assemblies concentrated in the region’s 1980s and 1990s condominium construction era.

Window System Replacement

Phased window replacement in occupied multi-family buildings using Andersen, Jeld-Wen, Marvin, Cascade, Milgard, and triple-pane systems throughout the Seattle Metro region.

Exterior Capital Improvement Programs

Multi-year, reserve-funded exterior capital improvement programs for HOA-governed communities and commercial properties throughout the Seattle Metro, phased across construction seasons and documented for reserve study and HOA governance purposes.

Consultant-Managed and Attorney-Directed Projects

Construction defect repair programs for HOA communities and commercial properties, executed under forensic consultant and attorney oversight across King, Snohomish, and Pierce Counties. The region’s concentrated EIFS-era construction is producing simultaneous defect discoveries across multiple communities.

Commercial Interior Painting

Interior painting programs for common areas, corridors, and occupied units in multi-family and commercial properties across the Seattle Metro.

Commercial Exterior Painting

Exterior painting and coating programs for multi-family and commercial buildings throughout the Seattle Metro, often paired with envelope remediation and siding replacement scopes.

Commercial Building Repairs

Structural and building envelope repair related to water intrusion, siding failure, and deferred maintenance across the Seattle Metro’s multi-family and commercial property inventory.

Multi-Family and Commercial Exterior Services

Comprehensive exterior services for multi-family and commercial ownership groups managing portfolios across King, Snohomish, and Pierce Counties.

What counties does Pacific Building Solutions serve in the Seattle Metro?

We serve King, Snohomish, and Pierce Counties, covering the core of the Seattle-Tacoma-Bellevue metropolitan area. We hold Washington Contractor License #PACIFBS831MK for all work in this region.

Does Pacific Building Solutions work in downtown Seattle, or only in the suburbs?

Both. We serve Seattle proper alongside our extensive King, Snohomish, and Pierce County coverage. Seattle’s mix of pre-1996 EIFS-era condominium stock and older postwar apartment inventory creates significant remediation needs across multiple neighborhoods.

How does Pacific Building Solutions manage projects across a metro area this large?

Our project management infrastructure is built for the Seattle Metro’s scale. We do not subcontract envelope remediation work to regional partners or franchise operators. Every project we execute is managed and performed by our own licensed crews under direct project management oversight, from Everett in the north to Tacoma and Gig Harbor in the south.

Can Pacific Building Solutions serve an ownership group managing properties across multiple Seattle Metro counties?

Yes. This is a standard configuration of our work. Ownership groups managing multi-family portfolios across King, Snohomish, and Pierce Counties work with our team in a single-contractor relationship. We handle permit coordination within each county’s specific jurisdiction and project management across geographically distributed properties without requiring separate contractor relationships for each county.

How does Pacific Building Solutions approach EIFS and exterior insulation remediation across the Seattle Metro?

EIFS and exterior insulation failure is the most common single scope in our Seattle Metro practice. The pre-1996 installation window maps directly onto the primary condominium and garden apartment construction era across Bellevue, Kirkland, Redmond, and dozens of communities throughout the region. Our remediation programs include full substrate assessment, weather barrier restoration, structural repair where required, and installation of James Hardie fiber cement or other appropriate replacement products.

Does Pacific Building Solutions coordinate with construction attorneys and forensic consultants across the Seattle Metro?

Yes. Working within attorney-directed and consultant-managed remediation environments is a core part of our practice across the Seattle Metro. We execute remediation scopes as specified by forensic consultants, report field conditions to the oversight team, and maintain the documentation chain required by legal environments. See our Consultants and Attorneys page for more details on how we operate within legal oversight environments.

The Seattle-Tacoma-Bellevue Metropolitan Statistical Area is the largest metropolitan area in Washington State and one of the fastest-growing large metros in the country, encompassing King, Snohomish, and Pierce Counties with a combined population of roughly 4 million residents. Seattle itself, incorporated in 1869, is the largest city in the Pacific Northwest and the seat of King County, situated on Puget Sound between Lake Washington and Elliott Bay.

The Seattle Metro’s built environment reflects three overlapping waves of development rather than a single steady growth pattern. The WWII-era Boeing manufacturing boom produced rapid, large-footprint apartment developments in south King County. The 1980s and 1990s brought a wave of garden apartment and condominium construction using exterior insulation and synthetic stucco systems now well past their expected service life. The 2000s and 2010s tech-driven growth wave, led by Microsoft’s Redmond expansion and Amazon’s Seattle headquarters growth, pushed dense multi-family construction into Bellevue, Redmond, Everett, and the Tacoma-Puyallup corridor, producing the region’s newest concentration of buildings now entering their first major maintenance cycle.
