Seattle, Washington is the seat of King County and the largest city in the Pacific Northwest, with a 2024 population estimate of approximately 755,000 residents. The city grew 21.1 percent between 2010 and 2020, making it one of the fastest-growing large cities in the United States, and that growth has been concentrated in dense multi-family construction across neighborhoods including Capitol Hill, First Hill, South Lake Union, and Ballard. Pacific Building Solutions holds Washington Contractor License #PACIFBS831MK and serves Seattle and the greater King County market for commercial and multi-family exterior envelope remediation.

Seattle’s building envelope environment carries a documented risk factor that distinguishes it from newer-growth markets: a wave of synthetic stucco and EIFS cladding installed on multi-family and condo buildings during the 1990s construction boom, before industry-wide secondary drainage standards took effect in 1996. The Seattle Times reported on this problem directly in 2001, describing the Puget Sound area as one of the regions hit hardest by EIFS failures nationally. Buildings from that era that have not undergone envelope assessment carry elevated risk of concealed moisture damage behind a cladding system that was never designed to drain.

We do not perform small residential repairs or new construction. Our work is focused on large-scale commercial and multi-family envelope remediation for HOA boards, property managers, construction attorneys, and ownership groups.

• Pre-1996 EIFS Installation Practice: Before fall 1996, EIFS insulation board was glued or nailed directly to the wall with no secondary waterproofing barrier beneath it. The system relied entirely on the exterior acrylic coating and caulking to stay watertight. The Seattle Times documented in 2001 that this installation era produced widespread failures across the wetter parts of the country, naming the Puget Sound area specifically. Buildings clad in this era’s EIFS or synthetic stucco without a documented envelope assessment carry unknown concealed moisture exposure.
• A Growth Boom Now Reaching Its First Major Maintenance Cycle: Seattle’s population grew 21.1 percent from 2010 to 2020, one of the fastest rates among large U.S. cities, driving a wave of mid-rise and podium multi-family construction across the city’s urban villages. Buildings from the earlier part of that boom are now 10 to 15 years old, the point at which envelope systems require their first serious inspection and, frequently, their first remediation scope.
• Mixed-Vintage Building Stock Across Dense Neighborhoods: Capitol Hill, First Hill, South Lake Union, and Ballard each carry a different mix of 1990s EIFS-era buildings alongside 2010s and 2020s construction, meaning HOA boards and property managers in the same neighborhood may be managing entirely different envelope risk profiles depending on the building’s construction year.
• Washington State Licensing and Statewide Coverage: We hold Washington Contractor License #PACIFBS831MK, covering the full state including King County and Seattle, and Oregon License #215897 for ownership groups managing properties across the Pacific Northwest.

Exterior Envelope Remediation

Full building envelope assessment and remediation for multi-family and commercial properties throughout Seattle. Our assessments prioritize identifying pre-1996 EIFS and synthetic stucco installations, the cladding era the Seattle Times identified as the source of the Puget Sound area’s documented failure pattern, before scoping repairs.

Multi-Family and HOA Siding Replacement

Large-scale siding replacement programs for condo associations and HOA-managed buildings across Seattle’s urban villages. For buildings carrying original 1990s EIFS or synthetic stucco cladding, we prioritize full system replacement over surface patching, since concealed moisture damage behind these systems is frequently more extensive than visible symptoms suggest. We work with James Hardie fiber cement, Cedar, Craneboard, and Stucco/EIFS replacement systems.

Water Intrusion Repair and System Restoration

Concealed moisture damage behind pre-1996 EIFS and synthetic stucco is Seattle’s most common water intrusion failure mode. We identify the extent of hidden damage, restore the building envelope, and document every phase for HOA boards, property managers, and legal oversight where litigation applies.

Construction Defect Repair and Forensic Consulting

When litigation or forensic consultant oversight applies, particularly for 1990s-era EIFS-clad buildings, Pacific Building Solutions brings the documentation protocols and scope discipline those environments require. We work alongside construction attorneys, owner representatives, and forensic consultants throughout Seattle and King County.

Does Pacific Building Solutions serve Seattle, Washington?

Yes. Pacific Building Solutions serves Seattle and the greater King County market for commercial and multi-family exterior envelope remediation, siding replacement, water intrusion repair, and related services. We hold Washington Contractor License #PACIFBS831MK and Oregon Contractor License #215897.

Why are 1990s EIFS and synthetic stucco buildings in Seattle considered higher risk?

Before fall 1996, EIFS insulation board was installed with no secondary waterproofing barrier, relying entirely on the exterior coating to stay watertight. The Seattle Times documented in 2001 that this installation era produced widespread failures across the Puget Sound area specifically. Buildings from this era without a documented envelope assessment carry unknown concealed moisture exposure behind a system that cannot drain.

How does Seattle’s recent growth affect envelope maintenance timelines?

Seattle grew 21.1 percent from 2010 to 2020, one of the fastest rates among large U.S. cities, concentrated in mid-rise and podium multi-family construction. Buildings from the earlier part of that boom are now 10 to 15 years old, the point at which envelope systems typically require their first serious inspection and remediation scope. We help HOA boards plan for this cycle proactively rather than reactively.

Does Pacific Building Solutions work on HOA-managed condo communities in Seattle?

Yes. HOA-managed condo and townhome communities are our primary project type. Seattle’s dense, mixed-vintage multi-family stock across neighborhoods like Capitol Hill, First Hill, and South Lake Union creates a consistent remediation project landscape for our team. We do not work on single-family homes or small residential repairs.

Is Pacific Building Solutions licensed to work in Seattle and King County?

Yes. We hold Washington Contractor License #PACIFBS831MK, which covers the full state of Washington including King County and Seattle. We also hold Oregon Contractor License #215897 for ownership groups with properties on both sides of the Columbia River corridor.

Seattle was first settled by European Americans in 1851 at Alki Point before relocating to the current downtown site along Elliott Bay, an area long inhabited by the Duwamish people. The city was named for Chief Sealth, who befriended early settlers, and was officially incorporated in 1869. Henry Yesler’s lumber mill, built in 1853, was the new town’s first major economic engine, supplying booming San Francisco and the growing towns of Puget Sound. The Klondike Gold Rush of 1897 accelerated the city’s growth substantially, and by 1910 the population had reached nearly 250,000.

Boeing’s arrival made Seattle the company’s headquarters city for decades, at one point employing one in five of King County’s manufacturing workers, and the city earned the nickname Jet City as a result. The 1962 World’s Fair, Century 21, brought international attention and the Space Needle. In the decades since, Seattle has become a global technology hub, home to Amazon, Microsoft’s regional presence, and a dense concentration of software and biotech companies, with its 2024 population estimated at approximately 755,000, the 18th largest city in the country.
