April Plumbing Alert: 5 Crucial Checks for Niagara Homes After Winter

April in Niagara: The Real Test for Your Home

As April settles into the Niagara Region, homeowners from St. Catharines to Welland, Grimsby, and Niagara Falls are beginning to notice the aftermath of a long Canadian winter. With snowmelt, April rain, and rising groundwater levels, your home’s plumbing and drainage systems are being put to the test—right now.

At McDowell Drain & Waterproofing, we’ve been helping Niagara homeowners for over 45 years, and April is when many of our emergency calls come in. Here’s what you should check now to avoid costly plumbing disasters later.

1. Is Your Sump Pump Keeping Up?

By April, your sump pump has already been working hard for weeks. If it’s noisy, constantly running, or has stopped working entirely—don’t wait.

April Action Tips

  • Check for standing water in the pit (a red flag).
  • Test by pouring in water to activate the pump.
  • Ensure the discharge pipe outside isn’t frozen or clogged.

Fun Fact: A well-maintained sump pump can last 10 years. But if yours is over 7, it might be time for a McDowell inspection.

2. Backwater Valves Need a Spring Checkup

Backwater valves are essential in April when municipal systems are overloaded with stormwater. If this device fails, sewage can back up into your home—especially in flood-prone areas like Niagara Falls, Thorold, and Fort Erie.

Check for

  • Slow drainage
  • Gurgling sounds in basement drains
  • Foul sewer odors

If your backwater valve hasn’t been cleaned this year, call us before the next rainfall—whether you’re battling wet basements or protecting a commercial space, McDowell has your back.

3. Watch for Window Well Leaks

Heavy April rainfall + thawed soil = water pooling around window wells.
This can leak directly into your basement, especially if the weeping tile isn’t connected or is clogged.

Check for

  • Water stains below basement windows
  • Cracks in the foundation around window wells
  • Pooling water outside windows

Pro Tip: McDowell installs drain-connected window wells to protect your foundation long-term.

4. Sewer Lines May Be Cracked or Root-Infested

Spring is when tree roots start searching for moisture—and cracked sewer lines are easy targets. If you’ve noticed slow drains or repeated clogs in April, your sewer line might be compromised.

Our Solution

  • Non-invasive sewer camera inspections
  • Trenchless sewer replacement
  • No digging up your driveway or lawn

5. Look for Basement Moisture Clues

April is mold season. Even tiny leaks from foundation cracks, floor joints, or old waterproofing can cause serious basement moisture issues.

Watch for

  • Warped drywall or baseboards
  • Mold or mildew along the floor
  • Damp, musty basement air

If you see these signs, it’s time for a professional waterproofing assessment.
