Transform Your Home's Exterior — Expert Siding Installation in Spokane
Licensed, bonded, and backed by a 5-year workmanship warranty. From LP SmartSide to James Hardie fiber cement, we install the best siding materials for Spokane's climate.
Why Spokane Homes Need Quality Siding
Spokane's four-season climate is tough on exterior materials. We experience brutal winters with freeze-thaw cycles that can split inferior siding, spring snowmelt that drives moisture behind walls, scorching summers with UV rays that fade and brittle paint, and dramatic temperature swings that cause expansion and contraction. Quality siding is your home's first line of defense against these conditions.
Freeze-Thaw Damage
Our winters crack and warp weak siding within 5-10 years
Moisture Infiltration
Spring snowmelt and rain can trap moisture inside walls
UV Degradation
Our intense summer sun fades and degrades paint yearly
Mold & Mildew
Poor ventilation behind siding creates mold growth
Installing quality, properly-installed siding protects your home's structural integrity, prevents costly water damage, improves energy efficiency, and increases curb appeal. It's one of the best investments you can make as a Spokane homeowner.
Siding Materials We Install
Each material has distinct advantages and trade-offs. We'll help you choose the best option for your home, budget, and maintenance preferences.
LP SmartSide
Engineered Wood
LP SmartSide is engineered wood from Georgia-Pacific—a blend of wood fibers and resins that delivers wood's beauty with engineered durability. It resists moisture, rot, and warping far better than traditional wood while maintaining authentic wood grain appearance.
Advantages:- Beautiful wood-grain appearance
- Excellent moisture resistance
- Won't warp in freeze-thaw cycles
- Mid-range pricing
- Energy efficient
- Requires painting every 10 years
- Cut edges must be sealed
James Hardie
Fiber Cement
James Hardie fiber cement is the gold standard for durability. Made from cellulose fiber, Portland cement, and silica, it's virtually indestructible—impervious to rot, insects, fire, and extreme weather. Homeowners who choose fiber cement rarely replace it again.
Advantages:- Exceptional durability (30+ years)
- Fireproof and rot-proof
- Resists all weather extremes
- Beautiful finish options
- Superior for coastal areas
- Higher initial cost
- Heavier (requires skilled install)
- Requires factory finishing
Vinyl Siding
PVC Material
Vinyl is an affordable, low-maintenance option made from polyvinyl chloride. Modern vinyl doesn't fade or crack as it once did and offers excellent color retention. It's the most installed siding in America for good reason: it works.
Advantages:- Most affordable option
- Never needs painting
- Lightweight & easy install
- Excellent color selection
- Very low maintenance
- Can be damaged by impacts
- Some fade in extreme UV
- Shorter lifespan than premium
Cedar & Wood
Board & Batten
For homeowners committed to maintenance and drawn to authentic wood aesthetics, cedar or redwood delivers classic beauty. It offers superior appearance and character but requires regular staining/sealing to survive Spokane's climate.
Advantages:- Stunning authentic appearance
- Natural insulation properties
- Customizable stain colors
- Character and warmth
- Requires sealing every 3-5 years
- Susceptible to rot in our climate
- Attracts insects without protection
- Higher upfront and maintenance cost
Our Siding Installation Process
We follow industry best practices to ensure your new siding performs perfectly in Spokane's climate and looks beautiful for decades.
Step-by-Step Process
Inspection & Assessment
We examine your current siding, substrate, insulation, and any hidden damage. We check for rot, moisture issues, structural damage, and code compliance. Drone photography documents everything, and we provide a detailed written assessment.
Material Selection & Proposal
Based on your home's condition and your preferences, we recommend materials and styles. You'll receive samples to see in person. Our proposal includes line-item pricing, timeline, warranty details, and material specifications.
Substrate Repair
If we find damaged sheathing, rot, or structural issues, we replace compromised materials. We may add weather barrier, house wrap, or updated insulation. Addressing substrate issues prevents future problems and ensures longevity.
Siding Installation
Using proper flashing, nailing techniques, and sealing methods, we install your new siding. Every corner, window, and door gets flashing to direct water away. We stagger joints and seal all penetrations to prevent moisture intrusion.
Trim & Finish Details
We install J-channel, corner trim, and fascia. We install soffit/fascia if needed, and ensure all windows have proper trim and caulk. Details matter—improper trim is the #1 cause of siding-related water damage.
Cleanup & Final Walkthrough
We remove all debris daily and do a final debris removal. We perform a detailed walkthrough with you, test all trim installations, and explain maintenance for your new siding. You'll love how your home looks.
Installation Timeline: Most siding projects take 1-3 weeks depending on home size and material choice. We provide a detailed schedule with your estimate and keep you updated throughout the project.
Siding Cost Guide for Spokane Homeowners
Costs vary based on home size, material choice, existing siding removal, substrate repair, and complexity. Below are realistic price ranges for a 2,000 sq ft home.
| Material | Cost Per Sq Ft | 2,000 Sq Ft Home | Includes |
|---|---|---|---|
| Vinyl Siding | $6-$9 | $12,000-$18,000 | Material, labor, trim, cleanup |
| LP SmartSide | $7-$11 | $14,000-$22,000 | Material, labor, trim, cleanup |
| James Hardie | $10-$15 | $20,000-$30,000 | Material, labor, trim, cleanup |
| Cedar/Wood | $8-$14 | $16,000-$28,000 | Material, labor, trim, cleanup |
Important: These are material and labor costs only. If substrate repairs (sheathing, insulation, house wrap) are needed, add $2,000-$8,000. Removal of existing siding typically adds $1,500-$3,000. Window trim work can add $500-$2,000. We provide a detailed, line-item estimate before any work begins—no surprises.
Financing Available: We offer 0% APR financing for 12 months, with payments starting as low as $89/month. Get pre-approved instantly with no impact to your credit score.
Signs You Need New Siding
If you notice any of these warning signs, your home needs attention. The longer you wait, the greater the risk of water damage and structural problems.
Warping or Buckling
Wavy or buckled siding indicates moisture behind the panels or substrate damage
Cracks or Splits
Visible cracks from freeze-thaw cycles or impact allow water infiltration
Moisture Behind Siding
Soft siding, peeling paint, or visible moisture signals water damage
Mold or Mildew
Visible mold growth indicates moisture problems requiring immediate attention
Fading or Chalking
Severe color fading or paint chalking indicates UV damage and possible underlying issues
Rising Energy Bills
If heating/cooling costs spike, damaged siding may be allowing air infiltration
Age Rule: If your siding is 20-30 years old, replacement is often more cost-effective and protective than repairs. Modern siding technology, better insulation, and improved durability make new siding a smart investment.

Siding Questions, Answered
For Spokane's freeze-thaw cycles and weather extremes, we recommend LP SmartSide (engineered wood) or James Hardie fiber cement. Both resist moisture, won't warp from temperature swings, and hold up exceptionally well in our climate. Vinyl is also popular for affordability and requires minimal maintenance. Avoid traditional wood siding unless you're committed to sealing it every 3-5 years—our climate is too harsh for unprotected wood.
Most siding projects take 1-3 weeks depending on home size and material choice. A typical 2,000 sq ft home with LP SmartSide takes about 10-14 days. James Hardie takes slightly longer due to installation requirements. Vinyl is quickest. Weather can impact timelines. We provide a detailed project schedule with your estimate and keep you updated daily throughout installation.
Look for warping, cracking, or soft spots in the siding; visible moisture or mold growth behind panels; gaps between boards; severe fading that won't wash off; or rapidly increasing heating/cooling bills suggesting air leaks. If siding is more than 20-30 years old, replacement is often more cost-effective than repairs. We offer free inspections to assess your siding's condition.
Yes. Our 5-year workmanship warranty covers all labor and installation. If anything fails due to our installation within 5 years, we fix it free of charge. Materials also come with manufacturer warranties: LP SmartSide (10-15 years), James Hardie (25-30 years), vinyl (10-15 years). You're fully protected.
Siding costs range from $6-15 per square foot installed depending on material choice. A typical 2,000 sq ft home costs $12,000-$30,000 for material and labor. Vinyl ($12-18K), LP SmartSide ($14-22K), and James Hardie ($20-30K) are most common. Substrate repairs, old siding removal, and window trim work can add $2,000-$10,000. We provide detailed, line-item estimates with no hidden fees.
We handle both repairs and full replacements. If damage is localized to a few panels, we can repair or replace just those sections. However, if there's widespread damage, warping, moisture intrusion, or substrate rot, full replacement is usually more cost-effective and provides better protection. We'll recommend the best approach based on your home's condition.
