Spokane County Home Improvement Guide

Last updated: March 2025

Spokane is not Seattle, and Spokane homeowners will be the first to tell you that. It's a point of pride. While the west side deals with mold, moss, and endless gray drizzle, Eastern Washington gets actual seasons—scorching summers, genuine winters with real snow, and the kind of temperature swings that stress-test every building system in your house.

If you own a home in Spokane County—whether it's a South Hill Tudor, a Five Mile craftsman, a Spokane Valley rambler, or a Liberty Lake new build—you're dealing with construction challenges that west-siders don't fully understand. The good news: Spokane has a robust contractor community that knows exactly how to handle this climate.

Eastern Washington Is Different

The Climate Reality

Let's talk numbers that matter:

Temperature range: -10°F to 100°F+ (110°F swing annually)
Freeze-thaw cycles: 100+ per year (concrete's worst enemy)
Heating degree days: ~6,700 (vs. Seattle's ~4,700)
Cooling degree days: ~700 (Seattle barely registers)
Snow: 45" average (your roof needs to handle real loads)

What this means for your house:

Heating systems matter more. Seattle homeowners can get away with a mediocre furnace. In Spokane, an inefficient system will cost you thousands over the winter. Heat pumps work but need cold-climate ratings (look for units rated to -15°F or below).

AC isn't optional. Unlike Seattle, where AC was historically a luxury, Spokane summers regularly hit 90s-100s. If your house doesn't have cooling, it's less desirable and less livable.

Foundations take a beating. The freeze-thaw cycle is relentless. Water seeps into cracks, freezes, expands, repeat 100 times per year. Concrete work in Spokane requires frost footings (typically 30" deep minimum per code).

Roofing needs to handle snow loads. 45 inches of snow doesn't sound like much until it's sitting on your roof. Spokane County requires roofs to handle 25-35 pounds per square foot snow loads depending on elevation.

Spokane Housing Stock by Era

The Grand Old Ladies (1890-1920)

South Hill, Browne's Addition, Cliff/Cannon, West Central

Spokane had money during the mining boom years, and it shows. The South Hill in particular has stunning brick Tudors, Craftsmans, and Colonials that rival anything in Seattle—at a fraction of the price.

These homes feature:

Solid construction (old-growth timber, real plaster, quality brick)
Character details (original woodwork, built-ins, hardwood floors)
Generous lot sizes (before density was a thing)
Mature landscaping (100-year-old trees = shade but also risk)

Common issues:

Outdated electrical (knob-and-tube common, fuse panels still exist)
Original plumbing (cast iron drains, galvanized supply lines)
Lead paint and asbestos (assume both until tested)
Foundation settling (100+ years = movement)
Single-pane windows (brutal in Spokane winters)
No AC (wasn't built for it, challenging to retrofit)

Renovation priorities:

Electrical upgrade (safety and insurance requirements)
Heating system efficiency (ROI is huge here)
Window replacement or storm windows
Foundation waterproofing
AC addition (mini-splits work well for retrofits)

Mid-Century Spokane (1950-1970)

North Side, Spokane Valley, Shadle, Audubon

Post-war boom brought standard American ranch houses and split-levels to Spokane. These homes are:

Single-story ranch or split-level (very common)
1,200-2,000 sq ft (modest by today's standards)
Built quickly but generally solid
On larger lots (half-acre not uncommon)

What you're dealing with:

Galvanized plumbing reaching end of life (60-70 years old)
Original windows that leak heat like sieves
Asbestos in floor tiles, insulation, texture coats
Outdated kitchens and baths (functional but dated)
Forced air systems that may be original or close to it

High-value upgrades:

Kitchen/bath modernization (these homes need it)
Window replacement (energy savings are significant)
Whole-house repipe (polyethylene or copper replacing galvanized)
Insulation improvements (attic first, then walls if accessible)
Furnace upgrade with AC addition

The Sprawl Era (1980-2005)

Spokane Valley, Mead, Five Mile, Eagle Ridge, Wandermere

Subdivision living came to Spokane. These homes are:

Larger (2,000-3,000 sq ft common)
Two-story layouts became popular
Built to code (but codes were less stringent)
Vinyl-clad windows (better than single-pane, not great)
Standard construction methods (nothing special, nothing terrible)

Common issues at this age (20-45 years old):

First major systems replacement due (HVAC, roof, water heater)
T1-11 siding rot issues (common exterior choice, now deteriorating)
Polybutylene plumbing in some homes (known failure risk)
Dated finishes (oak cabinets, brass fixtures, wallpaper borders)
Composite decking failures (early Trex-style products had issues)

What's worth updating:

Replace any polybutylene plumbing immediately
Furnace/AC replacement (efficiency gains are dramatic)
Siding replacement if T1-11 is failing
Cosmetic kitchen/bath updates
Energy efficiency improvements (insulation, windows)

New Spokane (2005-Present)

Liberty Lake, Spokane Valley South, North Spokane, Five Mile expansion

Modern subdivisions with:

Energy code compliance (better insulation, windows)
Two-story with three-car garages (the standard)
Open floor plans (for better or worse)
Engineered systems (designed but not over-built)

What to watch:

Builder-grade finishes (first to wear out)
Landscaping issues (new developments often have drainage problems)
HOA restrictions (check before starting any exterior work)
Warranty awareness (structural warranties may still apply)

Spokane-Specific Contractor Considerations

Seasonal Timing Matters Here

Unlike Seattle's year-round drizzle, Spokane has actual seasons that affect construction:

Spring (March-May):

Ground is thawing (bad for concrete, excavation)
Roofing contractors are slammed after winter damage
Exterior painting can start mid-April typically
Interior work is wide open

Summer (June-August):

Prime construction season
Contractors are busiest—book ahead
Great for concrete, roofing, siding, painting
AC installations are backed up (everyone wants it)

Fall (September-October):

Best value season for many projects
Contractors trying to fill schedules before winter
Good weather for exterior work still
Heating system work should be scheduled now

Winter (November-February):

Exterior work stops
Interior renovations are available
Heating contractors are busiest (repairs, emergencies)
Some contractors take time off

Pro tip: Schedule your furnace service in September. By November, HVAC contractors are slammed with emergency calls.

Getting Bids in Spokane

The contractor market in Spokane is different from Seattle:

Less saturated (fewer contractors per capita)
More relationship-driven (reputation matters a lot)
Generally lower prices (lower cost of living)
More availability (less competition for good contractors)

Typical bid counts needed:

For jobs under $5,000: 2-3 bids
For jobs $5,000-$25,000: 3 bids minimum
For jobs $25,000+: 3-5 bids (and check references)

License Verification

Same rules apply statewide. Every contractor must be registered with L&I:

Go to lni.wa.gov
Search by contractor name or license number
Verify:
- License is Active
- Bond and insurance are current
- License type matches the work
- No unresolved complaints

Spokane note: The region has a solid contractor community, but some unlicensed operators work the area. The low cost of living attracts both legitimate contractors and less scrupulous ones. Always verify.

Common Spokane-Area Projects

Heating & Cooling

The reality: Most Spokane homes need serious HVAC work at some point. The climate demands it.

What works in Spokane:

Gas furnace + AC (Most common)

Natural gas is widely available
Efficient modern furnaces (95%+ AFUE) are worth the premium
AC is essential, not optional
Expect $8,000-$15,000 for full system replacement

Cold-climate heat pumps

Now viable for Spokane with modern units
Must be rated to -15°F or colder
Can eliminate gas furnace entirely
Higher upfront cost, lower operating costs
Expect $15,000-$25,000 for quality installation

Ductless mini-splits

Great for older homes without ductwork
Excellent for additions and converted spaces
High efficiency both heating and cooling
$3,500-$7,000 per zone

What doesn't work:

Standard heat pumps (not rated for cold enough temps)
Evaporative coolers (humidity too variable)
Space heaters as primary heat (unsafe, expensive)

RCW 18.106 governs HVAC licensing in Washington. Your contractor must have an 06A (HVAC specialty) or 01 (general electrical) certification for any system work involving electrical connections.

Roofing

Snow loads are not optional. Spokane County requires roofs to handle 25-35 psf ground snow loads depending on location and elevation.

Popular choices:

Architectural shingles

Most common in Spokane
25-30 year warranty typical
Good value proposition
$8,000-$15,000 for typical home

Metal roofing

Increasingly popular in Eastern WA
Snow sheds better
40-50+ year lifespan
$15,000-$30,000 for typical home

Composite/synthetic

Emerging option
Good aesthetics
Long warranty
Premium pricing

Critical: Proper ice dam prevention matters in Spokane. Ice and water shield along eaves is essential, not optional.

Windows

This is where Spokane homes lose money. Single-pane windows in a 110-degree temperature swing climate are hemorrhaging energy.

What to specify:

U-factor: 0.25 or lower (lower is better)
Double-pane minimum (triple-pane even better for north exposures)
Low-E coating (essential)
Argon fill (standard now)
Quality frames (vinyl or fiberglass—wood requires maintenance)

Typical costs:

Vinyl replacement windows: $500-$800 per window installed
Fiberglass: $700-$1,100 per window installed
Wood-clad: $1,000-$1,500 per window installed

ROI: In Spokane's climate, window upgrades typically pay back in 7-12 years through energy savings. That's actually reasonable.

Concrete and Flatwork

The freeze-thaw challenge. Concrete in Spokane takes abuse that west-side contractors don't understand.

Specifications that matter:

4,000 PSI minimum (stronger than standard 3,000 PSI)
Air entrainment (5-7% air allows for freeze expansion)
Proper cure time (don't rush it, especially in fall)
Frost footings (30" minimum depth in Spokane County)
Drainage (water must not pool and freeze)

Best timing: Pour concrete between May 15 and September 15 when possible. Fall pours can work but require extra care and may need concrete blankets.

Typical costs:

Driveway (400-600 sq ft): $4,000-$8,000
Patio (200-400 sq ft): $2,500-$5,000
Sidewalk: $8-$15 per square foot

Basement Work

Spokane has a lot of homes with basements—more common than in Western Washington. This creates both opportunities and challenges.

Common basement projects:

Waterproofing

Many older Spokane homes have wet basements
Interior drainage systems: $5,000-$15,000
Exterior excavation/membrane: $10,000-$25,000
Sump pump installation: $1,500-$3,000

Finishing

Converting to living space is popular
Building code requires egress windows
Moisture control is critical before finishing
$30-$75 per square foot for finished basement

Foundation repair

Settling and cracking common in older homes
Crack injection: $300-$800 per crack
Pier underpinning: $1,000-$3,000 per pier
Full foundation work: $15,000-$50,000+

Working with Spokane Contractors

What to Expect

Responsiveness: Generally good. Spokane contractors tend to be more accessible than Seattle-area contractors. Lower population density means less competition for their time.

Pricing: 15-25% lower than Seattle for comparable work. Lower cost of living translates to lower labor costs.

Quality: Strong overall. The contractor community is established and reputation-dependent. Bad contractors don't last long when everyone knows everyone.

Communication: Tends toward direct and practical. Less sales pitch, more straightforward assessment.

Red Flags (Same as Anywhere)

Requires large deposit upfront (normal is 10-30%, not 50%+)
Can't provide license number or insurance certificate
Pushes to start immediately (good contractors are booked)
Significantly cheaper than other bids (why?)
Won't provide written contract or scope of work
High-pressure sales tactics
