Foundation Drainage in London & Surrounding Areas

Water pooling along the base of a home is one of the most common drainage concerns we see in London and surrounding areas. Foundation drainage focuses on how surface water behaves around your home — especially during heavy rain, rapid snow melt, and seasonal freeze–thaw cycles common in Southwestern Ontario.

When water collects tight to the foundation instead of moving away, it can increase pressure against exterior walls and raise the risk of long-term moisture issues. In many cases, the problem isn’t obvious until specific weather conditions reveal how water is interacting with the structure.

At Lawn Drainage London, we assess how surface water flows around your foundation before recommending any solution. Understanding where the water is coming from — and how it moves — is the first step toward protecting your home.

Our foundation drainage services in London, Ontario focus on directing surface water safely away from your home before it becomes a larger issue.

In London, Ontario and surrounding communities, foundation drainage issues are often seasonal and related to surface water movement around the home.

Why Water Collects Near Foundations

Water near a foundation is usually the result of surface water taking the easiest route — especially when the ground can’t absorb water as quickly as normal. In London and surrounding areas, this often shows up during heavy rain, rapid thaws, or back-to-back weather swings.

Common causes include:

  • Downspouts releasing water too close to the house

  • Snow melting while the ground is still frozen

  • Water travelling along hard surfaces (walkways, patios, driveways) toward the foundation

  • Saturated soil that can’t take on more water

  • Low spots near the foundation where water naturally collects

The key is identifying where the water is coming from and where it wants to go before choosing a solution.

Common Signs Water Is Collecting Near Your Foundation

  • Water sitting along the base of your foundation after rain or snow melt
  • Soil that remains wet or soft near exterior walls
  • Water collecting near basement windows or window wells
  • Downspouts draining too close to the house
  • Recurring damp areas in the same section of yard near the home
  • Ice buildup forming along foundation walls in winter

Our Assessment Approach​

In London, Ontario and surrounding communities, foundation drainage issues are often seasonal and related to surface water movement around the home.

Every property is different. Rather than recommending a one-size-fits-all solution, we evaluate real drainage behaviour around your foundation.

We look at grading patterns, downspout discharge points, soil saturation, and how nearby hard surfaces influence water flow.

Understanding the full picture allows us to recommend drainage improvements that address the source of the problem — not just the symptoms.

Foundation Drainage Solutions

Depending on what we identify during the assessment, solutions may include improving how surface water flows away from the foundation and preventing recurring pooling around the home.

Our goal is to reduce pressure against the foundation by managing surface water at the source.

  • Downspout extensions and discharge redirection
  • Catch basins to collect surface water in low areas
  • Drainage piping to move water away from the foundation edge
  • French drain installation
  • Surface drainage improvements to guide water away efficiently

Foundation Drainage vs. Waterproofing

Foundation drainage focuses on managing surface water outside the home before it has a chance to collect along the foundation or increase moisture risk. Waterproofing typically addresses moisture after it has already entered. In many cases, improving exterior drainage early can reduce the conditions that lead to recurring moisture concerns over time.
