Pacific Building Solutions is a commercial and multi-family exterior envelope remediation contractor serving the greater Portland Metropolitan Area, including communities throughout Multnomah, Washington, Clackamas, Columbia, and Yamhill Counties in Oregon and Clark County in Southwest Washington. We hold Oregon Contractor License #215897 and Washington Contractor License #PACIFBS831MK, and have operated in this region 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 Portland Metro is not a uniform building environment. Its multi-family housing inventory spans a median construction year of 1966 for the city of Portland proper, with surrounding communities ranging from post-WWII stock in Milwaukie and Oregon City to rapid-growth 1990s and 2000s HOA communities in Happy Valley, Sherwood, and Hillsboro. The Columbia River Gorge’s east wind exposure affects Troutdale and Camas differently than the Coast Range rainfall shadow affects Forest Grove. The Willamette River’s moisture conditions create specific envelope vulnerabilities in lake-adjacent Lake Oswego and river-level Oregon City that do not apply in inland communities at higher elevations. Understanding these variations across 47 cities and communities is not a generic capability. It is the product of nearly 30 years of executing large-scale envelope remediation programs across every county in the Portland Metro.

• Median Construction Year of 1966 for Portland Proper: Portland’s housing stock is among the oldest of any major Pacific Northwest city. With 26.8 percent of housing units built before 1940, Portland’s multi-family inventory includes pre-war buildings, post-WWII apartment stock, and waves of construction from every decade since. Each era presents distinct failure profiles. Pre-1960 buildings carry original wood siding, early vapor barriers, and first-generation window systems. 1970s-1990s construction carries LP Outer-Seal siding concentrations, failed flashing, and aluminum window systems. 2000s-era construction is entering the defect-discovery window simultaneously across multiple suburban communities.
• Urban Growth Boundary Driving Multi-Family Density: Oregon’s Urban Growth Boundary, established in 1979, has constrained outward sprawl and pushed development density inward throughout the Portland Metro. The result is a concentrated multi-family building stock, particularly in inner Portland neighborhoods and inner-ring suburbs, that requires ongoing envelope maintenance and remediation at a scale few other West Coast metros match.
• 1980s and 1990s Suburban Expansion Across Three Counties: The suburban growth wave that built much of Washington County’s Silicon Forest communities, Clackamas County’s south corridor cities, and Clark County’s north Vancouver suburbs during the 1980s and 1990s produced the LP siding, failed flashing, and weather barrier deficiencies that now drive remediation demand throughout the Metro. This is the primary remediation inventory across the region and the core of our practice.
• 2000s Rapid-Growth HOA Wave Now in Defect Discovery: Communities like Happy Valley, Sherwood, Wilsonville, and Battle Ground experienced population surges in the late 1990s and 2000s, producing concentrated waves of HOA condo and townhome construction. Those properties are now entering the construction defect discovery window simultaneously across multiple communities, creating a second wave of remediation demand on top of the 1980s-1990s inventory.
• Dual Oregon and Washington Licensing: The Portland Metro is a two-state region. Properties on the Oregon side require an Oregon Contractor License #215897. Properties on the Washington side require a Washington Contractor License #PACIFBS831MK. We hold both, with no handoffs, no referrals, and no regional gaps for ownership groups managing portfolios on both sides of the Columbia River.

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 Portland Metro, from inner Portland neighborhoods to the outlying communities of Clackamas, Columbia, and Yamhill Counties and Clark County, Washington.

LP Siding and Multi-Family Siding Replacement

LP Outer-Seal siding replacement is the most common single-scope work we perform across the Portland Metro. The 1975-1998 installation window for LP siding maps precisely onto the primary multi-family construction era in Gresham, Aloha, Tigard, Vancouver, and dozens of communities throughout the region. We have executed more LP siding replacement programs in the Portland Metro than any other scope in our nearly 30-year history.

Water Intrusion Repair and System Restoration

System-level water intrusion repair for multi-family and commercial buildings throughout the Portland Metro. The Pacific Northwest’s sustained wet-season loads build the envelopes continuously from October through May. Any gap in the weather protection assembly becomes a water intrusion pathway within that window.

Construction Defect Repair and Forensic Consulting

Construction defect repair programs for HOA communities and commercial properties, executed under forensic consultant and attorney oversight across all counties of the Portland Metro. The 2000s rapid-growth HOA construction wave in communities throughout the region is simultaneously producing defect discoveries across dozens of communities. We work alongside construction attorneys and forensic consultants on these programs as standard practice.

Window System Replacement

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

Structural Repair Related to Envelope Failure

Rim joist, bottom plate, sheathing, and stud repair caused by sustained water intrusion, executed as an integrated component of envelope remediation programs across the Portland Metro.

Mold Remediation Integrated Into Envelope Repair

Mold remediation was executed as part of the envelope repair scope that addresses the water intrusion source, producing it, not as a standalone surface treatment. Applicable throughout the Portland Metro’s older multi-family inventory, where sustained LP siding failure has produced secondary mold growth.

Exterior Capital Improvement Programs

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

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

We serve Multnomah, Washington, Clackamas, Columbia, and Yamhill Counties in Oregon, and Clark County in Southwest Washington. This covers the full Portland-Vancouver Metropolitan Statistical Area, plus the extended service-area communities in the Willamette Valley, Columbia County, and the Cascade foothills. We hold Oregon Contractor License #215897 for Oregon work and Washington Contractor License #PACIFBS831MK for Washington work.

Does Pacific Building Solutions work in the City of Portland itself, or only in the suburbs?

Both. We serve inner Portland neighborhoods, including multi-family properties in Northeast, Southeast, North Portland, and inner Northwest, alongside our extensive suburban coverage. Portland’s median construction year of 1966 and its concentration of pre-WWII and mid-century multi-family buildings create significant remediation needs across multiple neighborhoods. We will be adding dedicated neighborhood pages for Portland’s primary multi-family corridors as the next phase of our location content. For now, contact us directly to discuss any Portland property.

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

Our project management infrastructure is built for the Portland 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. Our base in the Portland-Vancouver corridor gives us efficient access to communities from Scappoose and St. Helens in the north to Salem and Newberg in the south, and from Sandy and Bend in the east to Forest Grove and McMinnville in the west.

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

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

How does Pacific Building Solutions approach LP siding replacement across the Portland Metro?

LP Outer-Seal siding replacement is the most common single scope in our Portland Metro practice. The LP installation window, roughly 1975 to 1998, maps precisely onto the primary multi-family construction era across the region. Gresham’s 1980s growth wave, Aloha’s 1984 median construction year, Tigard’s 1970s-1980s 99W corridor inventory, and similar concentrations throughout Clark County and south Washington County all sit within the LP era. Our LP replacement 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 Portland Metro?

Yes. Working within attorney-directed and consultant-managed remediation environments is a core part of our practice across the Portland 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 Portland Metropolitan Statistical Area is the largest metropolitan area in Oregon and the 25th-largest in the United States, encompassing Multnomah, Washington, Clackamas, Columbia, and Yamhill Counties in Oregon, and Clark County in Washington, with a 2020 combined population of approximately 2.5 million residents. Portland itself, incorporated in 1851, is the largest city in Oregon and the seat of Multnomah County, situated at the confluence of the Willamette and Columbia Rivers. The city’s median construction year of 1966, with 26.8 percent of housing units built before 1940, reflects its role as the Pacific Northwest’s oldest large urban center outside of Seattle.

The Portland Metro’s built environment reflects successive waves of development. The pre-WWII era saw the development of the dense inner neighborhoods of Portland proper. The post-WWII decade brought suburban expansion and the apartment boom that created the 1950s and 1960s multi-family stock now in the deepest remediation window. The 1970s and 1980s extended suburban growth into Washington County’s Silicon Forest corridor, Clark County’s north Vancouver communities, and Clackamas County’s south Portland communities, resulting in LP siding concentrations and weather-barrier deficiencies that drive the region’s primary remediation demand today. The 1990s and 2000s growth wave extended development to rapid-growth communities throughout the Metro, producing the HOA construction defect wave now surfacing simultaneously across dozens of communities from Battle Ground to Happy Valley to Wilsonville.

If you represent an HOA board, multi-family property management group, construction attorney, building envelope forensic consultant, owner representative, or commercial ownership group with a property anywhere in the greater Portland Metro area, Pacific Building Solutions welcomes the opportunity to discuss your project.
