Install New In-Ground Downspout Extensions, Repair Existing Underground Systems & Schedule Essential Maintenance

Managing excess water during heavy rainfall is not as complicated as you might think. Installing a downspout extension, also known as a gutter extension, is an effective yet affordable way to ensure that all excess water is channelled away from your property.

Connected to your eavestrough, these extensions are buried underground and lead water away from your property. Depending on your landscape’s draining capabilities, we might recommend installing a French drain system as well to ensure your property is adequately protected.

Underground Downspout Drainage FAQs

Underground downspout drainage systems are designed to effectively manage and redirect rainwater from your roof gutters away from your home’s foundation. This system involves installing pipes below ground level, connected to your downspouts, which transport water to a safe discharge point, such as a dry well, storm drain, or a designated drainage area in your yard. By channelling water away from your home, these systems prevent water accumulation around the foundation, which can lead to a variety of issues, including basement flooding, foundation cracks, and soil erosion. The buried pipes are typically made of durable materials such as PVC or corrugated plastic, ensuring long-term performance and reliability.

There are several signs that indicate the need for an underground downspout system. If you frequently notice water pooling around your home’s foundation or if your basement experiences dampness or leaks after rain, it’s a clear indication that your current drainage system is insufficient. Other signs include visible erosion in your yard, mildew or mould growth on your home’s exterior, and overly saturated soil near your foundation. These issues suggest that water is not being adequately directed away from your home, increasing the risk of structural damage and interior moisture problems. An underground downspout system can address these issues by efficiently managing and diverting runoff water.

Yes, underground downspout systems can be seamlessly installed in an existing landscape with minimal disruption. Our experienced team at DGI Waterproofing carefully plans the installation process to preserve the aesthetic integrity of your yard. We start by mapping out the most effective path for the drainage pipes, taking into account the landscape features and existing vegetation. The trenches for the pipes are dug precisely, and the pipes are buried at an appropriate depth to ensure they do not interfere with your lawn or garden. After installation, the trenches are backfilled and the surface is restored to its original condition, ensuring that your landscape remains beautiful and functional while effectively managing water runoff.

The installation time for an underground downspout system varies based on the project’s complexity and the size of the property. Typically, a standard installation can be completed within a few days. The process begins with a thorough assessment of your property to determine the best route for the drainage pipes. This is followed by excavation, pipe installation, and backfilling. Complex installations, such as those involving multiple downspouts or challenging terrain, may take longer. However, our team works efficiently to minimize disruption and ensure that your new drainage system is up and running as quickly as possible.

Regular maintenance is crucial for the optimal performance of your underground downspout system. It’s recommended to inspect the system at least once a year, preferably before the rainy season. During maintenance, check for any signs of clogs or blockages in the pipes, such as accumulated debris or sediment. Ensure that water is flowing freely from the downspouts through the pipes and out to the designated discharge area. If you notice any issues, address them promptly to prevent potential damage to your home’s foundation. Additionally, after heavy storms or significant rainfall, a quick inspection can help ensure that the system is functioning properly and prevent long-term problems.

Common problems with underground downspout systems include clogged pipes, improper installation, and damage from external factors. Clogged pipes can occur due to the buildup of leaves, dirt, and other debris, obstructing water flow. Regular maintenance, including cleaning the gutters and downspouts, can help prevent clogs. If a clog occurs, professional cleaning services can clear the blockage effectively. Improper installation, such as incorrect slope or poorly connected pipes, can lead to inefficient drainage. Ensuring that the system is installed by experienced professionals can mitigate this risk. Additionally, external factors like tree roots or soil shifting can damage the pipes. Regular inspections and prompt repairs can address these issues, ensuring that your underground downspout system remains functional and efficient.
