Follow these steps to keep your hemlock post and rail fence in top condition:

• Apply Linseed Oil to Below-Grade Post Sections (Before Installation):

  • For new installations, we strongly recommend treating the buried portion of your posts with linseed oil to protect against moisture and rot.

  • Mark the burial depth on each post (typically 2-3’ in Maine to resist frost heave).

  • Using a paint brush or rag, apply a generous coat of linseed oil to the post up to the mark. Let it dry fully (4-8 hours for boiled linseed oil, longer for raw).

• Inspect Your Fence Annually:

  • Each spring, walk the fence line to check for damage, loose screws, or signs of wear (e.g., cracking, splintering, or mildew).

  • Use a carpenter’s pencil to mark areas needing attention, such as rough spots or loose rails.

• Clean the Fence Surface:

  • Mix a mild soap or wood cleaner with water in a bucket.

  • Use a soft-bristle brush or sponge to gently scrub the fence, removing dirt, mildew, or algae. Focus on shaded areas where moisture may linger.

  • Rinse thoroughly with a garden hose or pressure washer on a low setting (high pressure can damage the wood).

  • Let the fence dry completely (1-2 days) before applying any treatments.

• Repair Minor Damage:

  • Tighten any loose screws securing the rails to posts using a screwdriver or impact driver. Replace damaged screws if needed.

  • For small cracks, consider filling with an exterior wood filler, then sand smooth once dry.

• Protect Above-Ground Sections (Optional):

  • While not required, applying a clear, UV-resistant exterior wood sealer to above-ground sections (posts, rails, gates) can protect against UV fading and weathering.

  • Use a paint brush or rag to apply the sealer evenly, following the manufacturer’s instructions. Reapply every 2-3 years or as needed.

• Monitor for Moisture and Drainage Issues:

  • Check the base of posts for standing water, especially after heavy rain. Ensure proper drainage by sloping soil away from the posts.

  • If you notice rot or softening in the buried sections, reapply linseed oil as described in Step 1.

• Prepare for Winter:

  • Before winter, remove any debris (e.g., leaves, snow buildup) from the fence to prevent moisture buildup.

Additional Tips for Maine’s Climate

• Frost Heave: Maine’s freeze-thaw cycles can loosen posts over time. If a post shifts, dig it up, re-level it, and backfill with compacted soil and gravel for better stability.

• Wet Conditions: Hemlock is prone to moisture damage if untreated. Regularly check for mildew or rot, especially in shaded or low-lying areas, and clean as needed.

• UV Exposure: In sunny areas, hemlock may fade over time. A UV-resistant sealer can help maintain its natural color.
