Maintenance & Durability

3Cycle structures are designed for decades of reliable performance. Proper maintenance ensures your building continues to perform optimally throughout its lifetime.

Design for Durability

Material Selection

Durability begins with material selection:

• Timber species - Select durable species appropriate for your climate
• Treatment standards - Protective treatments prevent decay and insect damage
• Hardware quality - Corrosion-resistant fasteners and connections last longer
• Sealants - High-quality sealants resist weathering and maintain flexibility

Environmental Protection

Proper design protects components from damage:

• Roof overhangs - Adequate overhangs protect walls from rain
• Drainage planning - Design slopes and channels to shed water
• Vapor management - Balance vapor transmission to prevent moisture accumulation
• Access for maintenance - Design ensures critical components remain accessible

Connection Design

Well-designed connections last longer:

• Mechanical connections - Reduce stress concentrations through proper design
• Load distribution - Connections spread loads to avoid overstress
• Movement accommodation - Allow for seasonal wood movement and settlement
• Inspection access - Design connections accessible for periodic inspection

Maintenance Program

Routine Inspection

Regular inspections catch problems early:

Annual inspection checklist:

• Exterior surfaces - Look for cracks, gaps, or deterioration
• Cladding condition - Check for loose boards or damaged sections
• Roof condition - Inspect for missing or damaged elements
• Sealants - Check for degradation or separation at joints
• Drainage systems - Verify gutters, downspouts, and site drainage work properly
• Access points - Inspect around utility penetrations for water intrusion

Seasonal inspections:

• Spring - After winter weather, check for damage and address issues
• Fall - Before winter, ensure building is weather-tight and systems functional
• After storms - Inspect for weather-related damage

Maintenance Tasks

Exterior Maintenance

Regular care keeps exterior surfaces protected:

Cladding care:
