Northern Kentucky's humidity means green algae and black mold grow on almost every exterior surface. Rinsing them off with a garden hose doesn't kill the spores — they grow back in weeks. Our sanitizing wash kills the growth at the root so it stays gone longer. Call 859-655-5435.
When You Need Mold & Algae Removal
Any green tint on siding, any black streaks on the roof, any slick shaded spot on the patio — those are all organic growth. They spread quickly in the Ohio Valley and stain the surfaces they live on. Address them the first spring you see them.
Mold is also a health issue when it spreads to areas near doors, windows, and outdoor living spaces where the family spends time.
Our Mold & Algae Removal Process
We identify the type of growth and apply the right sanitizing mix for the surface — siding, roof, deck, fence, concrete, or stone all take a slightly different approach. Low-pressure application, dwell time, then a clean rinse. Plants are pre-wet and rinsed after.
Timing depends on the size of the treatment area. Most residential jobs are done in a half day.
Mold & Algae Removal Cost in Union, KY
Pricing for mold and algae removal in Union, KY depends on square footage, how dirty the surface is, access, and any extra prep like stain treatment or landscaping protection. A larger area with heavy algae or old buildup takes more time and product than a light seasonal cleaning.
We give upfront quotes before we start — no hidden fees, no surprise add-ons, no trip charge. Most jobs are quoted the same day you call. Call 859-655-5435 for a free estimate.
