Big Sky Mountain Cabin Restoration
Log cabin wood staining at 7,500 ft elevation
Before & After Transformation
Before 
After The Challenge
This beautiful log cabin in Big Sky faced the extreme conditions that come with Montana mountain living at 7,500 feet elevation:
- • Severe UV degradation - At this altitude, UV radiation is 35% more intense than sea level, causing rapid wood graying and finish breakdown
- • Failed previous stain - Film-forming stain applied 5 years prior had cracked and peeled, trapping moisture against the wood
- • Wood checking - Large checks (cracks) had developed in logs, allowing water infiltration
- • Insect damage signs - Early evidence of wood-boring beetle activity required treatment
- • Short weather window - At Big Sky elevation, ideal staining conditions only exist for 4-5 months per year
Our Solution
We implemented our specialized high-altitude log home restoration process:
- ✓ Gentle media blasting - Corn cob media removed failed finish without damaging wood fibers or profile
- ✓ Borate preservative treatment - Applied Tim-bor to all logs for insect and fungal protection
- ✓ Check repair - Filled major checks with flexible backer rod and premium caulk
- ✓ Penetrating oil stain - Sikkens Cetol LOG & SIDING with maximum UV blockers
- ✓ Two-coat system - Applied wet-on-wet for maximum penetration and protection
High-Altitude Wood Staining Challenges
Intense UV Radiation
At 7,500 feet, UV radiation is 35% more intense than at sea level. Standard stains fail within 2-3 years. We use only maximum-UV-blocker formulations designed for mountain applications.
Freeze-Thaw Cycles
Big Sky experiences 150+ freeze-thaw cycles per year. Film-forming stains crack and fail. We use penetrating oil stains that move with the wood rather than sitting on top.
Wind-Driven Snow
Horizontal snow exposure means water contacts walls constantly. Our check filling and chinking inspection ensures no entry points for moisture infiltration.
Short Season
Ideal staining conditions at Big Sky elevation exist only May-September. We schedule projects precisely to work within proper temperature and humidity windows.
Our Log Home Staining Process
Assessment & Testing
Moisture testing of logs, evaluation of existing finish, identification of wood damage, and creation of detailed scope of work.
Media Blasting
Gentle corn cob or walnut shell blasting removes old finish without damaging wood grain or log profile.
Borate Treatment
Application of borate wood preservative for long-term protection against insects and fungal decay.
Check Repair
Filling of major wood checks with backer rod and flexible caulk to prevent water intrusion.
Two-Coat Stain
Application of premium penetrating oil stain with maximum UV protection, wet-on-wet technique.

Caulking & Sealing"Our Big Sky cabin was in rough shape after years of harsh mountain weather. Big Sky Painting brought it back to life. They really understood the unique challenges of staining at this elevation - the UV protection and wood treatment they recommended has kept our cabin looking amazing. Best investment we've made in this property."- David & Sarah K., Big Sky Cabin Owners

Log Home Maintenance Tips
Keep your mountain cabin looking great between professional applications:
Annual Inspection
Check for new checks (cracks), peeling finish, and signs of insect activity each spring before the season.
Clean Regularly
Wash walls annually with mild soap solution to remove pollen, dust, and mildew that accelerate finish breakdown.
Address Issues Early
Small touch-ups and caulking repairs are inexpensive. Waiting leads to major restoration projects.
Recoat on Schedule
Plan for maintenance coats every 3-5 years depending on exposure. South and west walls need more frequent attention.
