Exterior waterproofing stops water before it reaches your foundation walls. This is the most effective long-term solution because we create a complete moisture barrier around your entire foundation.

What we do:

  1. We carefully excavate around your foundation down to the footings
  2. Then, we clean and inspect your foundation walls for damage
  3. After that, we apply waterproof membrane and protective coating to the exterior walls

What we do:

  1. We use cameras to inspect your existing drain system and find problems.
  2. We excavate around your foundation to access old, damaged drain tiles.

  2. We use high-pressure water jetting to clear debris and buildup
  3. We remove tree roots that have grown into drain pipes

Sump Pump Installation Services

Clay soil in our region holds water, which is why many homes need sump pumps. We install reliable systems that automatically pump water out before it floods your basement.

  2. We record video as we navigate through your entire drainage system
  3. We identify blockages, cracks, root intrusions, or pipe damage

What are the Causes of Foundation Issues in Niagara Building?

Foundation problems are common in St. Catharines, Welland, Thorold, and Niagara Falls because of our local conditions. The biggest problem is our clay soil. When it rains, the clay gets bigger and pushes hard against your foundation walls. When it’s dry, the clay shrinks and your house can settle. Our cold winters make things worse because water gets into small cracks and freezes, making the cracks bigger. Many older homes in our area don’t have good drainage, so water sits around the foundation too long and causes damage.
St. Catharines Foundation Problems

St. Catharines has thick clay soil that swells up when it rains and shrinks when it dries out. This pushes and pulls on your basement walls all the time. Many older homes downtown and near Port Dalhousie don't have good drainage systems. When winter comes, water freezes in small cracks and makes them bigger. Lots of yards slope the wrong way, sending water right to your house.

Welland sits on clay soil near lots of water, which makes drainage tricky. Many houses were built fast back in the day without proper basement waterproofing. If you live near the old canal, you probably get more water around your foundation when it rains hard or snow melts in spring.

Thorold is built on hills, so water runs downhill and can pool around houses at the bottom. The soil is still mostly clay that moves around. Older homes downtown don't have the underground drain pipes that new houses have, so basements flood more often.

Niagara Falls stays wet all year because of the mist from the Falls. Houses near the tourist area and older neighborhoods deal with lots of moisture. The clay soil moves around, and all that extra wetness makes foundation problems happen faster. Your basement walls need more protection here than in drier places.

Why Should I Install a Window Well in My Home?

You should install a window well in your home because it prevents water and soil from leaking into your basement, allows natural light to enter and brighten the space, improves ventilation to reduce dampness, provides an emergency escape route to meet building code requirements, and helps protect your foundation from costly damage. Proper installation and regular maintenance will ensure your window well continues to keep your basement safe, comfortable, and protected for years to come.

Frequent basement leaks, damp smells, or window damage are early warning signs. You should be prepared for any misshapenning related to water damage because Basement flooding is Canada’s costliest hazard, causing over $40,000 in average damage per incident. (source) Here are some clear signs that it might be time to replace or upgrade your window well:

Our Window Well Installation Process

We install durable window wells with proper drainage, using steel or plastic materials, crushed stone, and optional covers to keep your basement dry, safe, and protected from water damage.

Interior Basement Waterproofing

Types of Window Wells We Install in the Niagara Region

In the Niagara Region, common types of window wells for basements include galvanized steel, concrete, and fiberglass. These wells are chosen for their durability to withstand the local climate, including freeze-thaw cycles. They are available in various shapes and sizes to accommodate different window types and building codes, including egress wells for emergency exits. It is essential that all window wells have a proper drainage system to prevent water accumulation. At McDowell Drain & Waterproofing, we install many kinds of window wells in homes across the Niagara Region including Thorold, St. Catharines, Welland etc. Our options include strong metal window wells, rust-free plastic ones, and stylish stone-look designs. Every home is different, so choose the right type that fits your requirements.

Here are the types we offer:

  • Metal window wells – strong, durable, and good for most homes
  • Plastic window wells – lightweight, rust-proof, and easy to maintain
  • Stone-look window wells – add a nicer look to your yard
  • Egress window wells – large enough for safe basement exits
  • Custom and deep wells – made for tall or unusual basement windows
  • Wells with drains and covers – help stop flooding and keep out debris

What is the Difference Between a Regular Window Well and an Egress Window Well?

The main difference between a regular window well and an egress window well comes down to purpose and safety. An egress window well is built to meet building codes as an emergency escape route, so it’s larger and often includes a built-in ladder or steps to make it easy to climb out in case of an emergency. A regular window well, on the other hand, is mainly there to let in light and keep water away from the basement window, without being big enough for someone to safely exit.

Here’s more detailed breakdown to help you understand better. 

Regular Window Well

  • Designed to keep soil and water away from basement windows.
  • Helps with drainage and lets in natural light.
  • No specific size requirements.
  • Commonly installed for non-bedroom basement windows.
  • May not allow a person to climb out in an emergency.

Egress Window Well

  • Specifically required for bedrooms or living spaces in the basement.
  • Must meet Ontario Building Code for emergency escape and rescue.
  • Requires a larger size (usually minimum 30″ projection from the wall and 3.77 sq. ft. of openable area).
  • Needs steps or a built-in ladder if deeper than 24 inches.
  • Always includes proper drainage to prevent water buildup.

Do Window Wells Need to be Attached to the Foundation?

Yes, window wells must be attached to the foundation to stay secure, prevent water leaks, and ensure proper drainage. This keeps them tight against the wall so they do not move over time from soil pressure or changes in weather. If they are not secured, gaps can form, letting water and debris into the basement. Using masonry anchors and sealant helps keep the well in place, prevents leaks, and makes sure it stays safe and stable if it needs to be used as an emergency escape.

Here’s why it is important:

  • Prevents shifting or collapse: Fastening the well to the foundation keeps it stable and in place, especially during heavy rains or soil movement.
  • Seals out water: Proper attachment helps create a tight seal between the well and the wall, reducing the risk of water leaking into the basement.
  • Maintains proper drainage: A fixed position ensures the well works correctly with the drainage system and doesn’t tilt or sink. 

Most window wells are attached using rust-resistant anchor bolts directly into the concrete foundation. This ensures long-term durability and safety.

Problem Explained by McDowell Team:

So here’s what’s going on, Mark. You’ve got some cracks in your basement wall – not huge ones, but big enough for water to sneak through when it rains hard. The real problem is your drain tiles around the foundation are plugged up with mud and junk, so the water just sits there against your wall instead of draining away. It’s like having a clogged sink – the water’s got nowhere to go.

Solution:

We gotta fix two things here. First, we need to clean out those drains so water actually moves away from your house like it’s supposed to. Then we seal up those cracks and put some waterproof stuff on your walls so water can’t get through anymore. Pretty straightforward fix.

What We’ll Do:

  1. Clear out all the gunk blocking your drains
  2. Fill in the cracks in your walls
  3. Put a waterproof coating on the inside of your basement walls
  4. Make sure everything’s working so water goes where it should

After that, when it pours rain, the water will flow away from your house instead of sitting there trying to find ways into your basement. No more puddles downstairs.
