“If we can see where problems occur, we can plan
ahead to prevent them.”-Gary Schroeder, The Log Home Maintenance Guide

Care of Logs Before Building
Care of Logs Before Building
If you are building from logs that you have obtained, consider how you will be treating them BEFORE construction begins.

Care of Logs Before Building
Care of Logs Before Building
• Remove all bark– Many insects nest between bark and wood– Bark absorbs and holds moisture
• Minimize checking (log cracks) and mildew– Peel and store two ft above ground– Space out to allow airflow
• Control sapstain– Spray wood with sapstain control– Apply within 24 hrs of peeling
• Treat with borates– PeneTreat or Timbor– Protects from fungus and insects– Apply to bare wood

Design for Easy Maintenance
Design for Easy Maintenance
• Design is closely linked to maintenance (poor design means more maintenance)
• Wood decay and insect damage are the two main issues involving log homes
• Wood+Heat+Water+Air=Decay In order to prevent decay, we need to control water

Design for Easy Maintenance
Design for Easy Maintenance
• Allow water to run off and away from the house– Slope grade away at least six inches
every 10 feet– Use self-draining notch styles– Use gutters and downspouts
• Keep sill logs at least two feet above the ground– Bottom logs are prone to rot due to
ground moisture and back splashing– Piled snow and decaying leaves
near wall can cause rot problems

Design for Easy Maintenance
Design for Easy Maintenance
• Reduce back splash hazards– Install gutters and downspouts– Keep objects away from walls
• Provide large roof overhangs– At least two feet– Log ends should not extend past roof
• Properly coat your logs– Do not use paint or a heavy coating
• Logs must be able to “breathe”
– Use a quality, pigmented finish• Clear finishes degrade quickly

Log InspectionLog Inspection• Inspect annually to stay ahead of issues• Start from ground up
– Problems identifiable at the bottom are often caused by issues overhead
• Take notes and photographs• Carry a pocketknife or awl
– Prod areas to check integrity

Log InspectionLog Inspection• Look for moisture problems and their sources
– Discoloration on lower logs and beneath windows– Areas of splash back from ground, deck and objects– Probe discolored areas to look for soft spots– Look for insect infestation evident by holes and frass– Keep vegetation a two ft minimum away from logs
• Look for areas needing caulk– Cracks let moisture & pests in– Cracks let heat out– Joints– Notches– Checks (cracks in logs)

• General treatment:– Use borates to
prevent infestation• PeneTreat or Timbor

InsectsInsects• Powderpost beetles
– Create many pinholes leaving a powdery frass– Prone to re-infest
• Round-headed wood beetles– Chew through wood, plasterboard, plywood, hardwood
flooring and carpeting– Most species do not re-infest, except for the old house borer
• Prevention and treatment– Use borate preservatives– Spot treat by injecting borates directing into holes– Use a finish with a contact insecticide in it

InsectsInsects
• Termites– Build tunnels through soil looking for wood
• Prevention and treatment– Consult local building codes– Seal cracks in foundation– Keep wood two ft above soil– Contact a local exterminator

Caulking and Chinking
Caulking and Chinking
• Log home caulking– Seal cracks and joints to limit
traffic of heat, moisture and pests– Use latex or polyurethane
caulking (silicone is not recommended for use with logs)
– Caulk upward facing checks, joints and other openings
– Use backer rod for proper joint design

Log Home FinishesLog Home Finishes• A quality log home finish needs to perform
successfully in five areas:– Provide UV protection– Provide rot resistance– Proved water repellency– Proved a flexible finish– Provide a breathable finish
• Surface preparation is key:– Dry wood (<18% moisture)– Weather damaged wood removed
• Sanding, blasting or power washing– Clean wood
• Dirt, dust and failing stain removed• Follow manufacturer’s directions:
– Surface and air temperatures– Application methods

Log Home DecksLog Home Decks• Wood preparation is key• Glossy, surface-film finishes are
very water repellant but are most risky for failure
• Penetrating finishes have dull luster but are more easily maintained
• Remove weathered wood before staining
• Power wash with a cleaning solution and rinse well
