Log Home Chinking & Sealant

Professional surface preparation for chinking and sealant systems designed to improve airtightness, prevent moisture intrusion, and protect your log home from environmental exposure.

Why Chinking and Sealants Matter

Protecting Your Log Home from Air and Moisture

Log homes naturally expand and contract as temperature and humidity levels change throughout the year. Over time, this movement can cause existing chinking and sealants to crack, separate, or lose adhesion.

When gaps develop between logs, outside air and moisture can enter the structure. This can lead to reduced energy efficiency, interior drafts, moisture problems, and conditions that support mold or biological growth.

Proper preparation and sealing help maintain a tight, weather-resistant building envelope and improve the overall performance of the home.

Our Surface Preparation Process

Preparation for Long-Term Sealant Performance CedarShield provides precision surface preparation to ensure proper adhesion of modern chinking and sealant systems. Our preparation process may include:

  • Removal of failed or deteriorated chinking
  • Cleaning and surface conditioning
  • Preparation of joint areas for proper bonding
  • Ensuring compatibility with modern materials

Proper preparation is critical to achieving a durable, flexible seal that performs under seasonal movement and environmental exposure.

Benefits of Professional Chinking & Sealing

Professional chinking and sealant systems help improve the airtightness of your log home, reducing drafts and improving energy efficiency. Properly sealed joints prevent moisture intrusion that can lead to wood deterioration, mold, or long-term structural issues. Modern flexible materials allow the system to move with the natural expansion and contraction of the logs, maintaining a consistent seal over time. When properly prepared and applied, chinking and sealants help protect the structure while improving indoor comfort and overall building performance.

Signs Your Log Home Needs Chinking or Sealant Work

When Joint Restoration is Recommended

  • Visible gaps or separation between logs
  • Cracked, brittle, or missing chinking
  • Drafts or inconsistent indoor temperatures
  • Signs of moisture intrusion near joints
  • Increased heating or cooling costs

If these issues are present, joint preparation and resealing may be necessary to restore proper performance.
