Hazel Dell, Washington, is an unincorporated census-designated place in Clark County, located north of Vancouver along Interstate 5. With a 2020 census population of approximately 23,569 residents, Hazel Dell is one of the most densely developed unincorporated communities in southwest Washington. It is also one of the communities in our service area where the specific construction history of the housing stock most directly shapes the type of remediation work we perform. Pacific Building Solutions holds Washington Contractor License #PACIFBS831MK and has served the Clark County commercial and multi-family market for nearly 30 years.

Hazel Dell’s development occurred in two distinct waves, each with its own set of building-envelope vulnerabilities. The first wave came after World War II, when thousands of new workers flooded into Vancouver to work in its factories and shipyards. Hazel Dell and the neighboring community of Minnehaha were among the first areas to absorb that growth, producing a layer of ranch-style and split-level construction from the late 1940s through the 1960s. The construction of Interstate 5 through the middle of the community in the early 1960s physically divided Hazel Dell into eastern and western halves, each with its own post office zone and its own development trajectory. That second wave, from the 1970s through the 1990s, produced the apartment complexes, condo communities, and HOA-governed properties along NE Hazel Dell Avenue and the Highway 99 corridor that are now firmly in the remediation window.

The 1970s and 1990s building era in Hazel Dell also coincides with the widespread installation of LP (Louisiana-Pacific) Outer-Seal siding, a wood-composite product that became the dominant low-cost siding choice in the Pacific Northwest during those decades, before its documented failure pattern led to class-action litigation in the late 1990s. Multi-family properties in Hazel Dell with LP siding still in place are carrying a known-failure product that significantly compounds their water intrusion risk. We do not perform small residential repairs. Our work is focused on large-scale commercial and multi-family envelope remediation.

• LP Siding Replacement Expertise: LP Outer-Seal siding was heavily installed in Hazel Dell’s 1970s through 1990s multi-family construction. The product is documented to fail by absorbing moisture, swelling, and deteriorating at the joint and edge lines. We are experienced in assessing LP siding systems, scoping full replacement programs, and selecting replacement products appropriate for Hazel Dell’s moisture environment.
• Two-Era Building Stock Knowledge: Hazel Dell’s post-war construction (1940s-1960s) and suburban build-out era (1970s-1990s) carry different failure profiles. Post-war properties often have original window systems, asbestos-era sheathing, and early aluminum or wood siding. Later-era properties carry LP siding, vinyl window failures, and moisture-barrier deficiencies. Our assessments are calibrated to each era.
• I-5 Corridor Direct Access: Hazel Dell is bisected by Interstate 5, accessible from exits 4 and 5. Our project management teams reach the area directly from our Portland Metro base without travel overhead.
• Washington State Licensing: We hold Washington Contractor License #PACIFBS831MK, the primary license for all work in unincorporated communities of Clark County, including Hazel Dell. We also hold Oregon License #215897.

LP Siding Replacement and Multi-Family Siding Programs

LP Outer-Seal siding replacement is among the most common scopes of work we perform in Hazel Dell’s multi-family and condo communities. Full LP removal, substrate assessment and repair, moisture barrier installation, and replacement with James Hardie fiber cement, Cedar, or Craneboard systems. We also address the window system and flashing failures that are typically revealed when LP siding is removed.

Exterior Envelope Remediation

Full building envelope assessment and remediation for Hazel Dell’s two-era building stock. Post-war-era properties (1940s-1960s) and suburban-era properties (1970s-1990s) carry different failure profiles. Our assessments are calibrated to each construction era and the specific moisture exposure conditions along the I-5 corridor.

Water Intrusion Repair and System Restoration

LP siding failure and moisture barrier deficiencies are the most common drivers of water intrusion in Hazel Dell’s older multi-family stock. We trace the source through the full building section, restore the system from the wall assembly outward, and document every phase for HOA boards, property managers, and legal oversight teams.

Construction Defect Repair and Forensic Consulting

LP siding installation during the 1990s is a documented context for construction defects in Washington State. When HOA boards or property managers in Hazel Dell are working with construction attorneys or forensic consultants on LP-related claims, Pacific Building Solutions provides the scope documentation and remediation execution that those environments require.

Window System Replacement

LP siding removal frequently exposes failed window systems in Hazel Dell’s multi-family properties. We replace window systems in occupied buildings using Andersen, Jeld-Wen, Marvin, Cascade, Milgard, and triple-pane systems, coordinating window replacement with siding programs to complete the envelope in a single mobilization.

Mold Remediation and Structural Repair

LP siding failure and sustained water intrusion in Hazel Dell’s older multi-family stock frequently produce secondary mold growth and structural compromise at the rim joist, sheathing, and stud level. We integrate mold remediation and structural repair into our siding replacement scopes rather than leaving those elements to separate contractors.

Does Pacific Building Solutions serve Hazel Dell, Washington?

Yes. Pacific Building Solutions serves Hazel Dell and the broader Clark County area for commercial and multi-family exterior envelope remediation, LP siding replacement, water intrusion repair, and related services. We hold Washington Contractor License #PACIFBS831MK and Oregon Contractor License #215897, and have operated in the Portland-Vancouver Metro region for nearly 30 years.

Does my Hazel Dell multi-family property have LP siding, and is it a problem?

LP Outer-Seal siding was the dominant low-cost siding product installed on multi-family and residential construction in the Pacific Northwest from the mid-1970s through the late 1990s. Hazel Dell’s suburban build-out era falls squarely within that window. LP siding is a documented failure product that absorbs moisture, swells at joints and edges, and deteriorates from the inside out. If your property was built between roughly 1975 and 1998 and has not had siding replaced, there is a meaningful probability that LP siding is present. A full envelope assessment will confirm this and scope the appropriate replacement program.

Does Pacific Building Solutions work on apartment complexes and HOA-managed condo communities in Hazel Dell?

Yes. Multi-family apartment communities and HOA-managed condo properties are our primary project type. We do not work on single-family homes or small residential repairs. Our projects are large-scale, multi-building remediation programs, and Hazel Dell’s density along the I-5 corridor makes it a consistent part of our Clark County project geography.

Can Pacific Building Solutions work with Hazel Dell HOA boards and construction attorneys on LP siding claims?

Yes. LP siding replacement in the context of HOA remediation programs, including those involving attorney oversight or forensic consultant review, is a familiar project environment for our team. We work alongside construction attorneys, owner representatives, and forensic consultants on documentation protocols and scope management throughout the remediation process.

How does Hazel Dell’s unincorporated status affect permitting for envelope remediation?

As an unincorporated Clark County community, Hazel Dell properties fall under Clark County permit jurisdiction rather than a city building department. Our project teams are experienced in navigating county-level permitting in unincorporated communities and handle permit coordination as standard project management.

Hazel Dell is an unincorporated area and census-designated place in Clark County, Washington, located north of Vancouver along the Interstate 5 corridor. Pioneer settlers Reese and Sarah J. Anderson established the community’s first homestead in the area, and Sarah named it after a stand of filbert trees on their land near 78th Street and Highway 99. She also donated the land for the first school in the community, the present site of Hazel Dell Elementary School. The community hosted the Clark County Poor Farm from 1873 to 1943, an institution that provided housing and work for indigent county residents. Remnants of the Poor Farm are preserved at Hazel Dell Park.

Before World War II, Hazel Dell was primarily agricultural, with horses and dairy cattle visible along Highway 99 and the I-5 corridor as late as the early 1970s. The post-war influx of workers into Vancouver’s factories and shipyards filled Hazel Dell with ranch-style and split-level residential subdivisions through the 1940s, 1950s, and 1960s. The construction of Interstate 5 through the community in the early 1960s divided Hazel Dell into northeastern and western halves, each with its own development trajectory. With a 2020 census population of approximately 23,569 and a total area of 4.85 square miles, Hazel Dell is bounded by the Vancouver city limits near Burnt Bridge Creek to the south, Lake Shore to the west, Salmon Creek to the north, and the Barberton area to the northeast.
