What we do
Waterproofing services in Milton
Exterior membranes, interior drainage, crack injection and sump pumps. Credit Valley Waterproofing will find where the water is actually getting in before quoting a fix, and put the warranty in writing.
Exterior foundation waterproofing
Excavate to the footing, clean and repair the wall, then apply a rubberized membrane and a dimpled drainage board such as Delta-MS before new weeping tile and clear stone go in. It is the one method that keeps water out of the wall itself instead of managing it after it gets through.
Interior weeping tile & drainage systems
Where the outside cannot be dug — a deck, an attached garage or a neighbour a metre away — we cut the slab at the perimeter, lay perforated pipe in clear stone to the sump, and run a dimpled membrane up the wall. Water still comes through the wall, but it goes to the pump instead of across your floor.
Sump pumps & battery backups
Cast iron Zoeller or Liberty pumps set in a proper sealed pit with a check valve and a discharge line that will not freeze shut in February. A battery or water-powered backup pump goes in for the storm that takes the power out, which is exactly the storm that fills the pit.
Foundation crack injection
Poured concrete cracks injected under pressure with expanding polyurethane, which follows the crack right through the wall and stays flexible as the foundation moves. Most cracks are done from inside in a couple of hours, with no digging and a written warranty on the repair.
Weeping tile inspection & replacement
Camera down the tile and the sump line to see whether the original clay or Big O pipe is crushed, silted or full of roots before anyone quotes an excavation. Flushing sometimes buys years; where the tile has collapsed we replace it and connect it properly to the sump or the storm sewer.
Window wells & well drains
Galvanized or plastic wells set to the right depth with a drain tied into the weeping tile, so a well that fills in a downpour is not a bathtub against your basement window. Covers and clear stone are included, and undersized wells are swapped for ones that meet egress for a bedroom window.
Grading, downspouts & surface water
Downspouts extended away from the foundation, negative grading built back up with clay-heavy fill, and walkways or patios that pitch toward the house dealt with. Half the wet basements we look at start with water being delivered to the wall by the house itself, and this is the cheap fix we try first.
Block, stone & rubble foundations
Older concrete block and stone foundations that cannot be injected get parged, sealed and drained from outside or lined inside, depending on what the wall will take. We tell you which one applies before quoting, because the wrong method on a block wall fails in the first spring.
About
About Credit Valley Waterproofing
Credit Valley Waterproofing started out fixing wet basements with a shovel and a wheelbarrow, and the approach has not changed with the size of the equipment: find where the water is actually getting in, fix that rather than the symptom, and pick the method the house needs instead of the one that pays best. Locates get called before every dig, trenches get shored, membranes go on to the manufacturer's detail, and the warranty is written down and goes with the house when it sells.

Ask for any of these before work starts — we are happy to send them over.
- WSIB coverage & $2M liabilityClearance certificate and certificate of insurance supplied before the excavator arrives.
- Ontario One Call locates before every digGas, hydro, water and telecom lines located and marked before a shovel or a machine touches the ground, as the law requires.
- Trenches shored to O. Reg. 213/91Excavations deeper than 1.2 metres are sloped or shored to the Construction Projects regulation, so nobody works in an unsupported trench beside your house.
- Manufacturer-warranted membranes & pumpsMembranes and drainage board installed to the manufacturer's detail so their warranty stands behind ours, with the paperwork left with you.
Questions
Before you call
Outside is the real fix: it stops water before it reaches the wall and keeps the concrete dry. Inside is a management system that collects water once it is through and sends it to a pump, and it is the right answer where digging is impossible or where the budget only stretches so far. We will tell you which one your house actually needs, and if you are getting other quotes make sure they are for the same method, because the prices are not comparable.
Usually not structurally. Hairline vertical cracks from shrinkage are normal in poured concrete and most of them can be injected from inside in an afternoon. What we look harder at is a horizontal crack, a stair-step crack in block, or one side of a crack sitting proud of the other, which can mean the wall is moving and needs an engineer before it needs us.
Crack injection is the cheapest job we do and is priced per crack. Interior systems and exterior excavation are priced by the linear foot and depend on depth, access, whether a deck or driveway has to come out, and what we find at the footing, so a real number needs a visit. We quote a fixed price for the scope in writing rather than a rate per hour that grows once the hole is open.
Only the wall that leaks, and only as wide as the machine and the trench need, which is usually about a metre off the foundation. Interlock, decks and gardens are lifted and put back, and we tell you before we start what will and will not survive the dig. Where the neighbour's house or an addition blocks access, an interior system does the job without the excavation.
Some municipalities, including Toronto, run basement flooding subsidy programs that pay part of a sump pump, a backwater valve or severing the weeping tile from the sanitary sewer; the rules and amounts change, so check your city's website or ask us what applies where you live. Home insurance generally covers a sudden event like a sewer backup if you carry that endorsement, but not seepage through a wall, which is why waterproofing is worth doing before you need to make a claim.
Crack injection is a couple of hours. An interior system is usually two to three days, and an exterior dig on one wall two to four days depending on depth and what has to come out and go back. We work spring through late fall and dig in winter when the ground allows; the busiest weeks are right after the spring thaw, so booking an assessment while the basement is still dry gets you a better slot.
