When downspouts discharge next to your foundation in Manteno, thousands of gallons of roof runoff can soak into the soil exactly where you don’t want it. Over time, this can lead to damp basement walls, foundation cracks, and soil erosion around your home after heavy rain. Allied Water Services installs underground downspout extensions in Manteno to safely redirect water away from your foundation and prevent long-term damage.
This process involves connecting your downspouts to buried piping that carries water at least ten feet away—often farther depending on your property’s slope and drainage conditions. The system can tie into existing drainage or discharge independently, ensuring water is moved efficiently without oversaturating your yard.
All installations are clean and discreet, with no exposed piping or unsightly splash blocks disrupting your landscaping.
If you’re noticing basement moisture or soil erosion around your Manteno home, redirecting your downspouts is one of the most effective ways to stop the problem at its source.
What's Included in This Service
The work starts by disconnecting your downspouts and digging a trench from each outlet to the discharge point. You'll see us install underground pipe, typically solid PVC or corrugated HDPE, sloped to carry water by gravity. The downspout connects to an inlet at ground level, and the pipe runs underground to a pop-up emitter, curb outlet, or drainage tie-in.
After installation, water from your roof flows underground and exits far from the house instead of pooling next to the foundation. Allied Water Services sizes the pipe to handle peak flow from your roof area, even during heavy downpours. The system reduces erosion, eliminates standing water near the house, and lowers the risk of basement leaks.
We use pop-up emitters that open under water pressure and close when flow stops, keeping debris and pests out of the line. If your lot has limited discharge options, we can tie downspouts into a larger yard drainage system or storm line. This service is compatible with gutter guards and can be added to homes with existing landscaping with minimal disruption.
Homeowners in Manteno & Northeastern & East-Central Illinois considering downspout drainage often want to understand how the system works and what results to expect. These questions address the most common concerns before installation.
Why Locals Choose This Option
Why is downspout drainage better than a splash block?
Splash blocks only move water a few feet and still allow it to soak into the soil near your foundation. Underground drainage carries it much farther and keeps it out of sight.
How far does the water need to discharge?
At minimum, ten feet from the foundation. On some lots, we extend it farther to reach a better discharge point like a swale, curb, or drainage system.
What if my yard doesn't slope away from the house?
We can still install underground drainage by running the pipe to a lower area, tying into an existing system, or using a discharge point at the street or property edge.
Will this prevent basement leaks?
Redirecting roof runoff reduces hydrostatic pressure around the foundation and eliminates one major source of basement moisture. It won't fix existing foundation cracks, but it stops water from reaching them.
What maintenance does the system need?
Very little. Keep downspouts clear of leaves so water can enter the pipe freely, and check pop-up emitters occasionally to make sure they're not blocked by debris or turf growth.
If roof runoff is saturating the soil near your foundation or causing basement moisture, underground downspout drainage moves that water where it belongs. Get in touch to discuss your property and schedule installation in Manteno & Northeastern & East-Central Illinois.
