Downspout Drainage

Residential Downspouts

Many damp and leaky basement walls can be resolved by simply addressing the downspouts around your home.

Here are some examples of downspout drainage issues:

  • Water ‘skips over’ the gutter altogether if they are too close to the home
  • Clogged downspouts and gutters can create a waterfall effect from the gutters
  • Downspout is not appropriate or placed correctly in proximity to the home

Downspouts can become even more effective when coupled with a downspout drainage basin. By adding a catch basin to an existing downspout, you can isolate and divert storm water away from your home and keep your basement dry. Catch basins come in a variety of sizes (up to 24″ square), with grates available in plastic, brass or cast iron options. We also have a selection of decorative cast iron and bronze grates for an added touch of backyard elegance.

3 Considerations


Storm water can cause areas of standing water if not effectively addressed. A catch basin will capture, hold and filter runoff water from roofs, lawns and off other surfaces.


Installing a catch basin will help to control water flow and erosion during periods of heavy rainfall and seasonal changes. Call our experts to find out which system is best for your project.


Clogged pipes reduce the effectiveness of drainage systems resulting in standing water and damage to property. Catch basin filters are a simple solution to keep water flowing.
