Top-Rated Commercial Fencing in Louisville, KY 40216 - Colonial Exterior Cleaning

Louisville's humid summers and frequent rain create ideal conditions for algae and mildew. Shaded areas near trees or fences close to the ground stay damp longer, encouraging growth. Overhanging branches can also drop organic debris that feeds spores. Colonial Exterior Cleaning’s soft wash treatment kills spores at the root and rinses away residue, preventing regrowth.

If you see dark streaks, green patches, or a slimy film that doesn't come off with a garden hose, your fence likely has embedded mildew or moss. A simple rinse only removes surface dirt; the roots remain and will return quickly. Colonial uses specialized detergents and low pressure to penetrate wood fibers, removing deep-seated stains and killing organisms. You'll also notice a musty smell near affected areas—another sign it's time for a professional cleaning.

It can if done incorrectly. High pressure can gouge wood, force water between boards, and strip paint. Colonial Exterior Cleaning uses adjustable low-pressure soft washing for fences and gates, combined with eco-friendly cleaners. This method safely lifts dirt and organic growth without harming the wood or seals. After cleaning, they can apply a protective sealant to guard against future moisture and UV damage, extending your fence’s life.
