Tuning up your sprinkler system for summer? Better check to see if you're watering the house, too. Correcting puddling, over-sprays and unclogging sprinkler heads should be done every spring. But is your home showing signs of moisture damage from repeatedly being doused with water intended for plants and shrubbery? If so, consider switching to a perimeter-drip system to irrigate areas immediately adjacent to your home. While sprinklers are great for large open areas, they can speed the deterioration of exterior surfaces and even cause hidden foundation problems below grade. A timed drip system slowly releases water right where it's needed without saturating the surrounding area or continually wetting the surface of your home. A greater percentage of water that is released at a slower rate also seeps down rather than accumulating and running off on the surface. If you see water damage or want to prevent it, change to a perimeter drip system now. And that's the On The House tip for today.
