    Professional concrete preparation for winter weather protection

    Why Winter Preparation Matters

    New Hampshire's brutal winters can be devastating to unprotected concrete surfaces. When water freezes in concrete pores and cracks, it expands by roughly 9%, creating tremendous pressure that can cause serious structural damage. Understanding proper winter care isn't just maintenance—it's protecting a significant investment in your property's value and functionality.

    Essential Pre-Winter Steps

    Before the first snowfall hits, inspect all concrete surfaces for hairline cracks or signs of wear. Even tiny cracks can become major problems when water freezes and expands inside them. Clean surfaces thoroughly, removing leaves, debris, and any staining that might trap moisture.

    Apply a high-quality concrete sealer if your surfaces haven't been sealed within the past two years. This creates a protective barrier that prevents water penetration while allowing the concrete to breathe naturally.

    Smart Snow and Ice Management

    Never use traditional rock salt directly on concrete surfaces. The chemicals can cause surface deterioration and accelerate freeze-thaw damage. Instead, choose calcium chloride or magnesium chloride-based deicers, which are much gentler on concrete while still providing effective ice control.

    When shoveling snow, use plastic rather than metal tools to avoid scratching and gouging the surface. Remove snow promptly—allowing it to repeatedly melt and refreeze creates the worst possible conditions for concrete damage.

    Spring Assessment and Recovery

    Once spring arrives, conduct a thorough inspection of all concrete surfaces. Look for new cracks, surface scaling, or any areas where the winter took its toll. Early detection and professional repair can prevent small issues from becoming expensive replacements.
