We may not notice it everyday. But your gutters are an important part of your home. You need to keep them clean on the inside so they properly carry water away from the house. But the outside of the gutters get dirty too. And to clean them you need know how. If its only dirt or mold on the gutters then you can clean them on your own if you want with soap, water, and elbow grease. But tar from the asphalt shingles also gets on the gutters and becomes chemically bonded to the aluminum. When that happens it will not come off without chemically un-bonding it. We can do that for you, safely protecting your house and plants, while restoring your gutters to like new condition. – h2oTEKS.com
