Regional cost illustration
Illustrative replacement cost bands for Seattle home maintenance projects
Seattle homeowners increasingly pair cold-climate heat pumps with supplemental strips — quotes bundle electrical capacity checks earlier than legacy AC swaps.
Moss-friendly north exposures shorten effective roof life versus south-facing slopes on the same ridge.

Regional bands synthesize publicly visible homeowner project summaries on aggregators such as HomeAdvisor and Angi together with broad labor-rate context from BLS occupational employment patterns — illustrative planning math only.
Why quotes diverge (labor, code, access)
Crawler-space moisture remediation piggybacks furnace swaps once crews discover rotted sill plates.
King County permitting portals add discrete fees that aggregator national ranges omit.
Illustrative replacement cost table
Numbers are rounded planning anchors only — not bids. Variance columns cite recurring scope creep Junyper users report when reconciling aggregator summaries with field quotes.
Estimated 2026 illustrative installed bands — Seattle metro (USD)
| Category | Low | Mid | High | Why spreads widen |
|---|---|---|---|---|
| Cold-climate heat pump | $10,500 | $18,900 | $31,500 | Breaker upsizing + line-hide |
| Gas furnace retire swap | $5,800 | $11,200 | $19,400 | Humidity integrated controls |
| Tankless electric (service limited) | $2,400 | $4,600 | $9,800 | Ampacity reality checks |
| Composition roof | $14,500 | $27,500 | $51,000 | Two-layer tear-off + plywood |
| Seismic water heater kit | $1,200 | $2,900 | $5,400 | Strapping + expansion routing |
| Panel + surge strategy | $3,100 | $7,200 | $13,800 | Meter-main combos |
These figures are not bids, guarantees, or insurance estimates. Permitting, accessibility, code cycles, supply spikes, and crew backlog widen real quotes — sometimes materially — versus any table. Aggregator dashboards such as HomeAdvisor and Angi summarize homeowner-reported project distributions; BLS occupational wage series explains why dense metro labor minutes cost more than rural schedules — Junyper ties your logged receipts to similar anchors when prioritizing projects.
Closing notes
Junyper reminders align roof moss treatments and gutter cadence with observed leaks — Seattle homes reward documenting exterior moisture, not just interior HVAC temps.
