Downspout Extensions for homeowners
The gutter systems installed on most homes today are a substantial contributing source of water around the house and throughout the yard. Many homes with yard drainage issues can significantly benefit from properly extending the gutter downspouts away from the home. When downspouts dump next to the house without being correctly routed away, the dirt becomes saturated, and several things happen. Water begins to pool in areas, and hydrostatic pressure begins to push on the home’s foundation. Over time this can lead to drainage and erosion issues, foundation settlement, and basement leaks. A properly installed drainage system is essential to protect your home.


Underground downspout extensions are a commonly overlooked item on homes and can contribute to water-related damage to the house. Keeping the gutter system cleaned and maintained, with extensions in place, is a top priority to protect your home from water damage. Over time, water can reach areas it shouldn’t. Rainwater can damage soffit and fascia boards, causing landscape erosion, basement flooding, and even structural damage. If these problems are not solved, water also can get under your roofline and damage your entire roof. In this case, your best option is to hire a professional.

We like to use smooth wall PVC to extend gutter downspouts to offer a permanent and serviceable solution. PVC lines flow better and are easier to clean when debris from the gutter enters the lines and creates a clog. PVC is a far better solution than corrugated lines; corrugated lines must be replaced when they clog.
We will determine the cost during our onsite inspection. It depends on the number of downspouts and their length.
