Downspouts should drain properly onto ground with splashpads
Downspout Drainage – Downspouts should drain properly onto ground with splashpads. Are your downspouts connected to the sewer system or your weeping tile (as shown in the photos below) ? If so they should be disconnected immediately and spilled onto the ground as shown in the photo above. Just remember not to direct downspouts at your neighbour’s property. By taking these steps you are also helping protect your basement from the possibility of flooding during a storm. During a storm the municipal sewer system can become overburdened just trying to keep the roads clear, the last thing the sewer system needs is drainage from your roof. The chances for sewer backup during a storm is a real possibility. If everyone took the time to disconnect their downspouts from the municipal sewer system the less likely hood there would be of sewer backup.

A cool, damp basement, musty smells, and maybe even mold or mildew on the walls are all indications of moisture getting into your basement. The main cause is likely poor drainage around your home that allows moisture to build up and remain in the soil around your foundation, and then work its way right through your foundation and into your home. Fixing drainage problems around your house can be a relatively inexpensive proposition, and it often come down to a couple of issues–how rainwater is handled and the grading or slope of your property.
