Wet Basements in Hamilton, From the Lower City to the Mountain
Where your house sits in Hamilton changes what is actually going on in your basement. In the lower city and on the Mountain north of Mohawk Road, much of the City's sewer system is combined. One pipe carries both sewage and storm water, and in a heavy storm it can run out of room. South of Mohawk, and in newer areas like Binbrook and Waterdown, the sewers are separated.
That matters, because a flooded basement has two very different causes. Water that comes up through the floor drain in a downpour usually means the sewer is backing up. The usual fix there is a backwater valve, which is a licensed plumber's job. Water that comes through the walls, up at the floor-wall joint or in through a crack is groundwater, and that is our work.
So every Hamilton call starts the same way: we find where the water actually gets in, then give you a straight answer on the fix.
-
Lower city & the Mountain north of MohawkCombined sewers and older homes. Storm backups and wall seepage both happen here, so we sort out which one you have before anyone quotes a fix.
-
South of Mohawk, Binbrook & WaterdownSeparated sewers. When water gets in here, the usual suspects are the walls, the floor-wall joint, the drainage around the house or a tired sump pump.
-
Century homes anywhere in the cityOlder foundations, and drainage that may still be original clay tile. These are the basements that suddenly turn wet after years of staying dry.
Leak Repair
Basement Leak Repair in Hamilton
A basement leak almost never starts where the water shows up. It runs along the wall, across the slab or down the framing first, so we trace it back to the real entry point before we fix anything. Most of the time that's a crack, the floor-wall joint, a window well or a downspout dumping beside the wall.
Then we fix the cause, not the stain. A leaking crack gets injected, and water at the floor-wall joint gets interior drainage to a sump. When the wall or the drain outside has failed, it's exterior waterproofing. If the real fix is a $20 downspout extension, we'll tell you that straight.
Read more about our basement leak repair, or work through the seven causes of a wet basement first.
Crack Injection
Foundation Crack Injection in Hamilton
Most leaking cracks in a poured basement wall are a one-visit job from inside. We drill ports along the crack, seal the face, and pump resin in under pressure until it fills the crack through the full thickness of the wall. No excavator, no torn-up garden.
Polyurethane seals a crack that leaks and still moves a little with the seasons, while epoxy bonds a dry crack back together. Plan on $500 to $1,500 per crack in Ontario, with every quote free and in writing. A horizontal crack or a bowing wall is a different conversation, and we'll tell you when you need an engineer.

Sump Pumps
Sump Pump Installation & Repair in Hamilton
A sump only handles the water that reaches the pit. So every sump pump installation we do is sized to the house and tested under load before we leave. When a pump runs nonstop, short-cycles or sits silent in a full pit, it's often a stuck float switch or a failed check valve. A sump pump repair can be the cheaper fix.
The City's Protective Plumbing Program offers a grant of up to $2,000 for single-family homes built before 2012. It goes toward a backwater valve, downspout disconnection and a sump pump installed with that valve. The full grant needs one of the City's pre-qualified contractors, and battery backups aren't on the eligible list. Check current terms with the City before you budget on it.
-
New pits and pumpsFor homes that never had one. We cut the pit, set a sealed basin and run the discharge well clear of the wall.
-
ReplacementsMost pumps are done after 7 to 10 years. We swap them before the old one quits in the middle of a storm.
-
Battery backupsThe storms that flood basements also take the power out. A backup keeps the pit pumping when the grid doesn't.
-
RepairsFloat switches, check valves and clogged discharge lines. We'll tell you when a repair makes more sense than a new pump.
Exterior Waterproofing
Exterior Waterproofing & Weeping Tile in Hamilton
When the wall itself is letting water through, or the weeping tile at the footing has silted up, crushed or quit, the lasting fix is outside. We dig down to the footing, clean the wall and seal it with a membrane and drainage board. Then we lay new weeping tile in clean stone and backfill so the ground slopes away.
It's the bigger job, and on a tight lower-city lot with a driveway down one side it takes planning. It also stops water before it ever reaches the concrete, which no interior system can do. Often it's one or two walls, not the whole house, and we only quote what has actually failed.

Why Hamilton Masonry Takes a Beating
Masonry & Brick Repair in Hamilton
Hamilton is a city of brick. Its huge stock of century semis and detached homes, from the tree-lined streets of the lower city and Westdale to the older pockets up on the Mountain, was laid in soft, locally fired brick and lime mortar that was never meant to be sealed up tight. A century later that masonry is fighting two things at once.
First, winters on both sides of the escarpment are hard on soft brick. Water soaks into brick and joints, turns to ice, and pops the brick faces off — the spalling and crumbling mortar you see on so many older walls. Second, the clay soil across the city shifts and holds water against foundations, opening cracks and pushing moisture into basements near the harbour and along the lower city.
That is why our most common Hamilton calls are spalling-brick repair, mortar-erosion repointing, foundation crack repair and exterior waterproofing — all matched to the soft historic brick these homes were built with.
See how we handle masonry and brick repair in Hamilton, and repointing when the joints are the problem. If your century home sits on stone, we do stone foundation repair too.

Hamilton FAQs
Waterproofing & Masonry Questions
Do you do basement waterproofing in Hamilton?
Yes — waterproofing is half of what we do. Exterior membranes, interior systems, foundation crack injection, basement leak repair and sump pump installation, all across Hamilton. If your basement gets damp when it rains, we'll find the cause and give you a straight answer on the right fix.
What does basement waterproofing cost in Hamilton?
Plan on $500 to $1,500 to inject one leaking crack from inside, and often $5,000 to $15,000 to dig out and waterproof one problem wall. Every Hamilton quote is free, written and itemized, so you'll know the real number before any work starts. Call (519) 802-2138 for a free assessment.
Is my basement flooding from the sewer or from groundwater?
Look at where the water comes in. Water rising through the floor drain in a big storm usually means the sewer is backing up. That's more likely where Hamilton's sewers are combined, in the lower city and on the Mountain north of Mohawk Road. Water through the walls, at the floor-wall joint or through a crack is groundwater, and that's the part we fix.
Can you waterproof a Hamilton basement from the inside?
Yes, in most cases. Crack injection seals a leaking crack from inside in one visit, and interior drainage along the footing carries water to a sump without digging up the yard. If the wall itself is failing, or the drainage outside has collapsed, exterior work solves more at once, and we'll say so.
Does the City of Hamilton have a basement flooding subsidy?
Yes: the City's Protective Plumbing Program offers single-family homes built before 2012 a grant of up to $2,000. It goes toward a backwater valve, downspout disconnection and a sump pump installed with that valve. The full grant needs one of the City's pre-qualified contractors, and battery backups aren't on the eligible list. Check current terms with the City at 905-546-2489 before you budget on it.
Do you offer free masonry quotes in Hamilton?
Yes. Every masonry repair and waterproofing quote in Hamilton is 100% free with no obligation. Call (519) 802-2138 or request a free quote online and we will arrange a visit to assess your brick, mortar and foundation and provide written pricing.
How fast can you reach Hamilton from Paris?
Hamilton is a short drive from our Paris home base, so our crew reaches neighbourhoods across the city quickly. For urgent issues like a leaking foundation we do our best to prioritise a fast response.
Can you match the mortar on a century brick home in Hamilton?
Yes. Many Hamilton homes are century-old brick semis and detached houses built with soft lime mortar. We match the colour, texture and joint profile so repointing and repairs blend with the original masonry and protect the soft historic brick.
What does masonry repair cost in Hamilton?
A few spalled bricks or some spot repointing is a small job; rebuilding a section of wall is a much bigger one. After inspecting the work in person we give a clear written quote so you know the price before any work begins.
Do you fix spalling brick and mortar erosion caused by winter weather?
Yes. Water soaks into soft century brick, freezes and pops the faces off, and the same water washes out old lime mortar. We replace damaged brick, repoint failing joints and address the water entry behind the problem so it does not return.
