Why Basement Flooding Is on the Rise in Oakville—and What Homeowners Can Do About It
As rainfall intensifies and aging infrastructure continues to challenge Oakville neighborhoods, more local homeowners are discovering an unwelcome surprise—water backing up into their basements.
According to 17 Plumbing, a licensed local emergency plumbing service, calls related to basement flooding and sewer backups have spiked over the past 12 months, particularly in Glen Abbey, River Oaks, and Bronte.
“Most people don’t think about their basement drains or sump pump until water starts bubbling up or pooling around their floors,” says a lead technician at 17 Plumbing. “But these are preventable problems if you catch the signs early.”
What Causes Basement Water Backup?
Common causes include:
Sewer line blockages from tree roots or grease buildup
Heavy rainfall overwhelming storm systems
Failing sump pumps or clogged floor drains
Improper gutter drainage directing water toward foundations
The consequences? Mold, property damage, and sometimes thousands of dollars in restoration costs.
What Can You Do?
The plumbing team at 17 Plumbing recommends:
Annual drain and sewer inspections
Sump pump testing and battery backup systems
Backwater valve installation (rebate-eligible in some cases)
Keeping gutters clean and downspouts directed away from your home
Local Oakville Case
One recent call in Glen Abbey involved a family whose floor drain began backing up during a summer storm. Within 45 minutes, 17 Plumbing had inspected, cleared the line, and installed a new backwater valve—preventing a future repeat.
“Prevention and fast action are key,” the technician adds. “We’re available 24/7 because water damage doesn’t care about office hours.”
