Basement waterproofing Where's the water coming in?

Basement waterproofing in Hamilton

Albany Contracting Group does basement waterproofing in Hamilton and nearby towns. Tell us where you see the water. We'll find where it gets in, then fix it at the source.

Which one sounds like yours?

  • It's coming in somewhere. We just don't know where.

    Where the water shows up says a lot about why. The City of Hamilton sorts basement flooding the same way, by where the water comes in. Pick the one that looks like yours.

    It came up through the floor drain. Or out of a toilet or sink downstairs. That's a sewer back-up, not a wall problem. The City asks you to call 905-546-2489 to report it. Do that first.

    It comes in at the basement window. That's overland flooding: rain running toward the house instead of away from it. The City points at grading and window wells. Look at which way the ground slopes outside that window.

    It's coming through the wall, or up through the floor. That's infiltration. When the soil around the house is soaked, water pushes in wherever it can. This is what most people mean by "the basement leaks".

    It's just damp. I can't tell. A dark corner, a tide line on the drywall, a musty smell every spring. Send a photo of each and we'll start there.

  • It only happens after a big rain.

    That usually means the ground outside is full and the water is finding a way in. Snowmelt in spring does the same.

    Next rain, go down and look while it's happening. Note the wall, the corner and the height. A photo with the time on it tells us more than a description.

We find where it gets in, then fix it there.

We come to the house and look at the inside and the outside. We find where the water gets in, and you hear what it needs at the free consultation in your home, before any work starts.

Do we fix it from inside or outside?

It depends on where the water comes in. Some houses need work inside, some outside, some both. We waterproof foundations, basements and exterior surfaces, so we pick the side that stops your leak.

We want to finish the basement. It gets damp sometimes.

Fix the water first. New drywall and flooring over a wall that leaks is the job you pay for twice. Get the source found and fixed, then finish the basement once it's dry. We do both, so the people who saw the wall build the room.

The storm flooded us this year.

    What affects the cost of basement waterproofing

    No two basements leak the same way. These change the price most:

    • Where the water gets in:one corner, one wall or several.
    • Inside or outside:which side the fix needs, or both.
    • Access:a deck, a driveway, steps or a garden against the wall.
    • What's in the way inside:finished walls, flooring and stored things.
    • What we find once it's open:the wall behind the drywall or under the soil.

    Every job is priced at the free in-home consultation, once we've seen it.

    Questions we get

    How much does basement waterproofing cost in Hamilton?

    Every basement waterproofing job is priced at the free in-home consultation, because where the water gets in and which side needs the fix change the price more than anything else. We look, explain what it needs, then give you the price. No obligation.

    Is it better to waterproof a basement from inside or outside?

    It depends on where the water gets in. We look at both sides of the wall and tell you which your house needs, and why, before any work starts.

    Water came up through my floor drain. Who do I call?

    Call the City of Hamilton at 905-546-2489, because water from a floor drain or fixture is a sewer back-up. For the City's programs after this year's storm, see 2026 storm damage? Start here.

    Why does my basement only leak in spring?

    Snowmelt and spring rain soak the soil around the house, and water pushes in through the wall or floor. Take photos while it's wet and text them to us.

    Can I send photos before anyone comes out?

    Yes. Text photos of the water to (289) 860-0200 with your town, and we call you back to talk it through.

    Do you waterproof basements outside Hamilton?

    Yes. We work in Hamilton and nearby towns, including Burlington, Ancaster, Dundas, Stoney Creek and Oakville.

    We just want to stop moving boxes every time it rains.

    Leave a number. We call you back, then price it at a free consultation, once we've seen where the water gets in.

    1. Tell us. Call, fill in the form, or text us photos of the water.
    2. We call you back. We talk it through and book a time.
    3. Free consultation at your home. We find where the water gets in, and you get your price.

    What are you planning?

    No obligation.

    Your consultation is free and in your home. It goes best when everyone in the decision can be there.
