Edmonds Insulation — R-49 Attics, Crawl Space Sealing & PSE Rebates
The ferry terminal at the foot of Main Street sits roughly 40 feet below Edmonds's hillside residential streets — and the moisture off Puget Sound climbs every one of those feet into crawl spaces, uninsulated rim joists, and attic assemblies last touched in the 1970s. Homes in the Meadowdale and Perrinville areas were mostly built when R-11 was considered sufficient and vapor barriers were optional. That's a long way from the R-49 that Washington State Energy Code now requires for attic assemblies in Snohomish County's climate zone 4C. Bringing an older Edmonds home up to current energy standards usually means blown-in cellulose to full depth, closed-cell spray foam on the rim joists, and a proper vapor barrier in the crawl space — three scopes that can often be completed together and may qualify for PSE (Puget Sound Energy) rebates. TopVolk Construction LLC, owner-operated by Vladislav Volkov, has completed 100+ projects across King and Snohomish counties since 2017.

The 98020 zip code covers downtown Edmonds and the waterfront neighborhoods — homes near Brackett's Landing and the ferry terminal corridor tend to be 1950s-to-early-1970s construction, often on post-and-pier or concrete perimeter foundations with open, unconditioned crawl spaces. The 98026 zip runs through the higher inland areas including 5 Corners and the Perrinville corridor, where 1970s split-levels and 1980s builder-grade homes are more common. Split-levels in 98026 frequently have knee wall cavities at the upper half-story — those bays are often left completely uninsulated during original tract construction, and they're one of the most consistent heat-loss bypasses in homes of that era. PSE serves the vast majority of Edmonds residents and runs active rebate programs for attic blown-in insulation, floor insulation, and crawl space improvements. Permit jurisdiction in Edmonds is the City of Edmonds permit center — not Snohomish County PDS, which handles unincorporated county areas — and most standalone insulation projects don't require a permit unless they're folded into a larger remodel scope.
Common Insulation Concerns in Edmonds
Attic Insulation Below R-49 in Edmonds's Mid-Century Homes
A large share of the homes in the 98020 zip were built with R-11 or R-19 fiberglass batts in the attic — and after five decades of settling and compression, the effective R-value is significantly lower than that. Washington State Energy Code requires R-49 in attic assemblies for climate zone 4C, which covers all of Snohomish County. Getting there on a retrofit usually means blown-in cellulose over the existing material, with air-sealing at top plates and electrical bypasses completed first. Owens Corning AttiCat blown-in fiberglass is a solid alternative for tighter attics where cellulose dust is a concern. On a typical 1,300-square-foot attic in Edmonds, the full scope — air-sealing included — runs roughly $3,000–$5,200. Most attic-only projects in Edmonds do not require a building permit from the City of Edmonds permit center, which keeps the schedule clean.
Crawl Space Moisture Without a Proper Vapor Barrier
Post-and-pier foundations in Edmonds's older hillside neighborhoods leave crawl spaces directly exposed to ground moisture year-round. Puget Sound averages close to 37 inches of rain annually, heaviest from October through May, and that moisture moves up through unprotected crawl space soils into the floor framing above. A proper fix starts with a 6-mil polyethylene vapor barrier lapped and taped at all seams, then 2-inch XPS rigid foam board against the stem walls for thermal break and secondary moisture control. On homes near Brackett's Landing, the original black poly barrier — where it still exists at all — is frequently torn, shifted, or barely stapled to joists without meaningful overlap. Full crawl space encapsulation on a mid-sized Edmonds home typically runs $4,500–$9,000 depending on square footage, debris removal, and whether drainage corrections are needed before the barrier goes down.
Rim Joist Air Leakage in 1960s and 1970s Frame Construction
The rim joist runs around the perimeter of the floor system directly above the foundation wall — and in 1960s Edmonds construction, it is almost always uninsulated and a significant air leakage point. Even homes where attic insulation has been upgraded often lose a disproportionate share of conditioned air through those open rim joist bays in the crawl space. Closed-cell spray foam at 2-inch depth (approximately R-13) both insulates and air-seals in one pass, which no batt product can do. Dow Froth-Pak two-component kits handle smaller perimeters; a full-perimeter rim joist treatment on a larger home calls for contractor-applied closed-cell. This scope regularly qualifies for PSE air-sealing rebates. Cost typically runs $900–$2,200 depending on linear footage and access. Combining rim joist spray foam with a vapor barrier replacement on the same visit cuts mobilization cost for both scopes.
Uninsulated Knee Walls in Edmonds Split-Levels
Split-levels and 1.5-story homes throughout the 98026 zip — particularly in the 5 Corners area — frequently have knee wall bays that were left completely open during original construction. A knee wall is the short vertical wall separating conditioned living space from the unconditioned attic area in a partial upper story. Without insulation and an air barrier on the knee wall face, those upper rooms are essentially in thermal contact with the exterior through the January and February cold stretches. Rockwool Safe'n'Sound mineral wool batts work well in knee wall stud bays — they're dimensionally stable and don't compress or slump over time the way fiberglass can. Rigid foam board on the cold side provides the air barrier layer. This scope typically adds $1,400–$3,000 to an attic project on a standard Edmonds split-level, and the improvement in upper-story comfort is immediate.
PSE Rebates and What the Full Insulation Scope Actually Costs
PSE offers rebates on qualifying insulation upgrades — blown-in attic, floor insulation, and crawl space improvements all have eligibility tiers based on the improvement delta from existing conditions. The rebate process requires pre-project R-value documentation and post-project verification, which means whoever does the work needs to measure and record existing conditions before starting. TopVolk handles that documentation as part of the project scope — no separate energy auditor required for most residential jobs. A combined attic and crawl space encapsulation project in Edmonds typically runs $8,000–$15,000 before rebates. PSE incentives can reduce the net cost by $400–$1,500 depending on scope and current program funding levels. A missed completion deadline costs us money — that penalty is written into every contract.

Frequently Asked Questions
How fast can you get to Edmonds for an insulation assessment?▼
Edmonds is roughly 20 miles north of Seattle — about 30 to 40 minutes via I-5 or Highway 99 depending on traffic. Vladislav can typically schedule a free on-site assessment within the week for addresses in both the 98020 and 98026 zips. Estimate-to-contract turnaround is usually 3 to 5 business days for a standard attic or crawl space scope. Call (206) 591-1096 to check current availability — TopVolk is owner-operated, so you're scheduling directly with the person who will run the project and show up on site.
What does attic insulation to R-49 cost in Edmonds?▼
For a typical 1,200-to-1,600-square-foot attic in Edmonds, blown-in cellulose or Owens Corning AttiCat to R-49 runs roughly $2,800–$5,500. The main cost drivers are access conditions (pull-down stair versus no hatch), how much existing material needs to be worked around, and whether air-sealing top plates and electrical bypasses is included — which it should be for the upgrade to actually perform at the rated R-value. PSE rebates, where applicable, typically reduce the net cost by $300–$1,200. All pricing comes as a written line-item quote after the on-site assessment, not a vague phone range.
Do I need a permit for insulation work in Edmonds?▼
Most attic blown-in and crawl space vapor barrier work in Edmonds does not require a building permit from the City of Edmonds permit center. Closed-cell spray foam on rim joists generally falls under routine maintenance as well. Where permits do apply: if the insulation scope is part of a larger remodel — kitchen gut, addition, ADU — it gets rolled into that project's permit set submitted to the City of Edmonds. Snohomish County PDS handles unincorporated areas nearby, but incorporated Edmonds has its own permit center on 5th Avenue North. TopVolk is a WA Licensed Contractor and handles permit applications when the project scope requires them.
Is blown-in cellulose or fiberglass batts better for an older Edmonds attic?▼
Blown-in cellulose outperforms added fiberglass batts for retrofit work in older Edmonds attics almost every time. Older homes have obstructions — blocking, original wiring, HVAC penetrations — and cellulose fills around all of it without leaving thermal bypasses. Batts require consistent depth and full cavity contact to hit their rated R-value, and in an irregular 1960s attic, that's genuinely hard to achieve. CertainTeed blown-in cellulose settles predictably to the target depth and has a slight moisture-buffering quality that suits Edmonds's persistent damp winters better than fiberglass. The trade-off is that blown-in requires a blower machine and clean attic access — tight knee wall spaces add setup time.
What warranty covers the insulation work TopVolk installs?▼
Material warranties vary by product. CertainTeed blown-in cellulose carries a lifetime limited warranty against settling below the installed R-value. Dow Froth-Pak and contractor-applied closed-cell foam products carry manufacturer warranties of 10 to 20 years depending on the specific product line. Rockwool mineral wool batts are rated for the life of the building with no degradation in R-value. Our workmanship warranty covers installation quality for 2 years from project completion — if something fails or was installed incorrectly within that window, Vladislav comes back to address it. No argument about whether the issue is a material defect or an installation problem.
Do you cover Lynnwood, Shoreline, and other cities near Edmonds?▼
TopVolk covers the full north King and Snohomish County corridor — Lynnwood, Mountlake Terrace, Mukilteo, Shoreline, Lake Forest Park, Mill Creek, and Kenmore are all regular service areas. Permit jurisdictions shift by city: Lynnwood and Mukilteo run their own permit centers, some Mill Creek addresses fall under Snohomish County PDS, and Shoreline has its own permit office. Scheduling windows for new insulation assessments across this area are typically 1 to 2 weeks out. Call (206) 591-1096 to check availability for your specific address — 100+ projects completed across the Seattle Metro since 2017.
