Barrie and Simcoe County since 2004
Follow the water, find the spot it gets in, fix that spot. From inside if we can, from outside if we have to, with a warranty that stays with the house.
What we do
Barrie Quality Waterproofing has been fixing wet basements in Barrie since 2004: leaking cracks, damp floors, drains that quit after 30 years, the puddle that shows up every March. Most of the time we stop it from inside, with a crack injection or a drain under the edge of the floor running to a sump pump. When the wall itself is failing, we dig to the footing and seal it from outside with membrane and new weeping tile.
Most of our repairs carry a transferable lifetime warranty, so the next owner gets it too. Our own crew does every job, start to finish; we haven't used a subcontractor in over 20 years. The 50-point check is free, and you get the price in writing before anyone touches a shovel. Straight answer: if a $20 downspout extension fixes it, that's what we'll tell you.
Twelve things we fix, roughly in the order Barrie homeowners call about them. Your basement probably needs one or two, not twelve, and we'll tell you which on the first visit.
We dig down to the footing, pressure-wash the wall and patch every crack and tie rod hole. Then two layers of waterproof membrane go on, the way a goalie pad's shell takes the shot before anything behind it does. New weeping tile goes in under clear stone before we backfill. It costs more than inside work, but water never touches the wall again. See exterior waterproofing.
We cut a strip of floor along the leaking walls and lay new drain pipe beside the footing. That pipe runs to a sump pit. Water coming through the wall or up at the cove joint (the seam where wall meets floor) drops into the drain instead of running across your floor. The yard isn't touched. See interior waterproofing.
Most leaking cracks in poured walls are thin shrinkage cracks, and we've injected thousands of them. Flexible polyurethane resin goes in under pressure from inside and fills the crack right through the wall, like stitching a cut instead of taping it. It stays flexible through freeze-thaw. Half a day, usually. See foundation crack repair.
A sump pit at least 750 mm deep, which is the Ontario Building Code minimum, and a submersible pump in it. A check valve stops pumped water from running back down. The discharge line carries it well away from the wall. And a battery backup, because the storm that fills the pit is the one that takes the power. See sump pump installation.
The drain around your footing silts up or gets crushed after 30 or 40 years. We've pulled a full wheelbarrow of silt out of one pipe. We camera the line where we can, then replace only the run that failed, with new pipe in filter sock under washed stone. Outside with exterior work, or inside as an interior drain. See weeping tile replacement.
Water on the floor after the melt or a big storm comes from one of four places: a crack, the floor seam, a plugged footing drain or roof water dumped beside the wall. Every time we trace one, it's the same detective work. Find the source, fix that, leave the rest alone. Most wet basements in Barrie need one repair, not a whole system.
One leak at a window, a pipe running through the wall or a tie rod hole can often be sealed in a couple of hours. We inject the gap around the pipe and patch the parging (the grey cement skin) outside. Small leak, small bill. If the leak moves around from spring to spring, it gets a proper diagnosis instead.
Basement windows that sit below the soil line fill up with melt and leak at the frame. A steel window well keeps soil and water back. Inside it goes clear stone, plus a drain down to the weeping tile. Add a clear cover and you won't be shovelling it out in February. Barrie jobs usually run $1,800 to $3,200 per well.
Damp crawl spaces rot wood and push musty air up into the house. We sort the drainage first. Then a heavy vapour barrier goes over the soil and up the walls, sealed at the seams. A dehumidifier goes in where the space needs one. You end up with a dry, clean space you'd actually store things in.
White chalky stains (that's efflorescence) mean water is moving through the wall. So do peeling paint and a musty smell. We stop the source first, then dry the space out. Health Canada suggests keeping indoor humidity between 30 and 50 percent. You won't get there with a wet wall.
Hollow cinder block walls fill with water like a sponge, and old stone walls leak through the mortar. We've found block cores holding water two rows up. These walls need different treatment than poured concrete: weep holes and drainage that empty the cores, or a full exterior membrane on the worst walls.
Some cracks are more than a leak. Bowing walls, stair-step cracks in block or a dropped corner need structural repair: carbon fibre straps on a bowing wall, epoxy where a crack needs strength, or helical piers under a settling corner. We'll tell you straight whether it's structural or just wet.
Our main services
Tap a service to see what it fixes, what's in the job and what it usually runs in Barrie.
Published Barrie range: $95 to $350 per linear ft
Our crew digs to the footing, fixes the wall, puts on two waterproof layers and lays fresh weeping tile in clear stone. Water stops before it ever reaches the foundation.
What's included
Published Barrie range: $70 to $240 per linear ft
Our crew lays a new drain under the edge of your basement floor, right beside the footing, and runs it to a sump pit. The yard, the deck and the garden all stay exactly where they are.
What's included
Published Barrie range: $500 to $3,200 per crack
Flexible resin goes into the crack under high pressure and fills it right through the wall. About half a day, nothing dug up, and if that crack ever leaks again we come back free.
What's included
Published Barrie range: $995 to $2,995
Pit dug to code. Submersible pump inside it, check valve on top. A discharge that lets go well clear of the wall. Battery backup for the night the lights go out.
What's included
Published Barrie range: $70 to $350 per linear ft
After 30 or 40 years, the pipe around your footing either fills with silt or gets squashed flat. A camera shows us which stretch quit, and that stretch is all we replace.
What's included
A recent job
A poured-wall house in south Barrie, water along the back wall every spring for three years. The owners had painted that wall twice (it never works). We found a crushed run of weeping tile and two hairline cracks. Morning one, we injected both cracks. Then we laid 41 feet of interior drain to a new sump pit and set a battery backup pump beside the main one. The next March melt came and went. Dry floor.
Pricing
Going by prices Barrie contractors published in 2026, basement waterproofing in Barrie usually costs $500 to $3,200 to inject one crack, $70 to $240 per linear foot for an interior drainage system and $95 to $350 per linear foot for exterior waterproofing. A full interior system on a typical house runs $8,000 to $18,000.
These are the ranges Barrie contractors published in 2026 (the Dryshield and MT Drains city pages), before HST. What moves your number most: how many feet of wall, how deep, how much of the basement is finished, and whether a deck or driveway sits on top of the dig. Your written price comes after the free check.

Barrie sits in a snowbelt and averages about 286 cm of snow a year. It lies on the ground from late November to the end of February, then goes in a few weeks of March. All of it soaks into the soil beside your foundation at once, and the water table rises. We joke that March is our Christmas: the phone rings off the hook from the first warm week until mid-April.
Soil matters too. A lot of Barrie lots have fine, clay-heavy soil that drains slowly and holds water against the wall for days. Wet soil leans on the foundation (that's hydrostatic pressure) and squeezes water through any gap it finds. A crack, a tie rod hole, the cove joint or a failed weeping tile will all do.
Then there's age. Barrie's population tripled between 1981 and 2006, so a big share of houses are 20 to 40 year old subdivisions with poured walls. Builders sprayed them with damp-proofing, the thin black coat that slows dampness but can't stop running water, and by now it's cracked along with the wall. Older homes in Allandale and near Kempenfelt Bay have block or stone foundations that leak in their own ways.
The City of Barrie pays part of the bill when you stop sending groundwater and roof water into the sanitary sewer. Under its Disconnect to Protect program (2026), the numbers are:
If your weeping tile still drains into the sewer, we can do the disconnection and set the new pit and pump in one visit. Check the current rules on barrie.ca before you start, though. The City sets the terms and pays the rebate, not us.
How it works
Every job follows the same five steps, from the first visit to the warranty.
Step 01 · Inspection
Outside first: grading, downspouts, window wells, the parging. Then inside: every wall, the floor seam, the pit, every stain. We take photos as we go. It takes about an hour and costs you nothing. Where does it show up first? That one question usually tells us half the story.
What you get
Step 02 · Price
You get the plan on paper: what we'd do, how many feet of wall, what it costs. If the cheap fix will work, it goes at the top of the page. We'd rather you spend $300 on downspouts this year than $9,000 on a drain you didn't need.
What you get
Step 03 · Prep
Before a shovel goes in, we book Ontario One Call so gas, hydro and cable get marked. If the job needs a permit, like a Barrie foundation drain disconnection, we pull it. Inside, floors get covered and the work area gets walled off with plastic.
What you get
Step 04 · The work
Crack injections take half a day. Inside drains take two to four days, outside jobs three to seven. You stay in the house the whole time. We sweep up every evening, because nobody wants to step over a trench at 6 a.m.
What you get
Step 05 · Warranty
We test with a hose or by filling the pit until the pump kicks on, then walk you through what we did and what to watch. You get the photos and the warranty, which on most repairs is a transferable lifetime one.
What you get
A few jobs that don't fit the list above but come up every week around Barrie.
Cutting a bigger window or a side entrance into a foundation wall is waterproofing work as much as carpentry. We cut the opening, set the window or door, then seal and drain it so it doesn't become next year's leak. A bedroom window needs at least 0.35 m² of clear opening under the Ontario Building Code.
Drywall over a damp wall is how mould starts where nobody can see it. We check and fix the walls first so your contractor builds on a dry foundation. Honestly, it's the cheapest time to do it: before the studs go up, the whole wall is right there.
Cracks patched from inside with caulking or hydraulic cement usually leak again within a few years. It's like taping a cracked visor: fine in warm-up, gone on the first real hit. We grind out the old patch and inject the crack through its full depth. It's one of our most common calls.
Roof water dumped beside the wall is the cheapest leak there is to fix. We extend downspouts at least two metres out and build up low spots so the ground slopes away. If you ask us, about a third of spring calls end right here.
Think of it as the backup goalie: you hope it never leaves the bench, but when the starter goes down it has to be ready. A battery backup pump sits beside the main one and takes over when the power drops or the main pump fails. We add one to an existing pit in a few hours.
If your weeping tile drains into the sanitary sewer, Barrie wants it disconnected. We cap the sewer connection, set a sump pit and pump, and run the discharge out to the lawn. The City's Disconnect to Protect program can cover 75% of the cost, up to $2,000.
We also waterproof foundations under small commercial and rental buildings around Simcoe County. Same methods, same crew, scheduled around tenants and opening hours.
A leak in a basement apartment is a tenant problem and a building problem at the same time. We work around the tenant, do crack injections in a morning, and run interior drains a section at a time so the unit stays livable.
Foundations under shops and offices leak for the same reasons houses do. We book exterior digs around parking and opening hours, and seal the spots where services come through the wall.
Every unit or wall gets a written diagnosis with photos, so the board can see what has to happen now and what can wait a year. One person from our crew handles the whole job.
We've been fixing basements in Barrie and around Simcoe County since 2004. That's more than 20 spring melts, and the same few problems over and over: cracks, tired drains and roof water landing in the wrong place. After that long, most basements tell us what's wrong before we've put the flashlight away.
Most of our repairs carry a lifetime warranty that transfers to the next owner. If a crack we injected leaks again, we come back and fix it free. When you sell, the buyer's inspector sees the photos and the paperwork, and that conversation gets a lot shorter.
We do both, so we have no reason to push the expensive one. In our experience most Barrie basements are fixed from the inside, and we start there whenever it solves the problem. Digging up a yard is the right answer less often than people are told.
No subcontractors. Every new crew member spends two years as an apprentice before leading a job, and our senior techs have five years or more in the trenches. The people who look at your basement are the people who fix it.
What homeowners say
A few notes from homeowners our crew has worked for.
Water at the back wall every single spring. They found a crushed drain nobody else had mentioned, put in an inside system and a backup pump, and it's been dry since. Clean, on time, and the bill matched the quote.
Three cracks in a poured wall, all injected in one morning. They showed me exactly where the old patch had failed and why. Not a drop this spring.
They told us to extend the downspouts and fix the grading before spending a dime on anything else. That fixed half of it. The other half was one crack, done in a morning.
Our old stone foundation leaked every heavy rain. They dug out the worst wall, sealed it and put in new weeping tile. Big job, four days, and they put the garden back the way it was.
New pit, pump and battery backup in one day. They also walked us through the City rebate paperwork for the drain disconnection.
We manage a fourplex near downtown. They did the basement unit a section at a time so the tenant could stay put. Kept us posted the whole way.

Questions
Most Barrie basement waterproofing jobs we quote land between $500 and $18,000. One crack injection runs $500 to $3,200, an interior drainage system $70 to $240 per linear foot, and exterior waterproofing $95 to $350 per linear foot, going by 2026 published Barrie prices. HST is extra, and the free inspection sets your exact number.
Interior waterproofing fixes most Barrie basements for less money and without digging up the yard, and that's where we start. Exterior waterproofing is better when the wall itself is failing, when you want water stopped before it touches the wall, or on block and stone foundations. We price both when both would work.
Barrie gets about 286 cm of snow a year, and most of it melts in March. The soil beside your foundation fills up, the water table rises, and that pressure pushes water through cracks, the floor seam or failed weeping tile. Plenty of basements we see are bone dry in July and wet every single March.
Yes. Most leaking cracks in poured concrete walls are fixed from the inside by injecting flexible polyurethane resin under pressure. It fills the crack through the whole thickness of the wall and stays flexible as the house moves. One crack usually takes us about half a day, and nobody digs anything.
You need a sump pump if your weeping tile drains to a pit instead of a sewer, if you're disconnecting the foundation drain under Barrie's rebate program, or if you're adding an interior drain. We put a battery backup with every pump we install, because heavy storms so often cut the power.
Yes. Under Barrie's Disconnect to Protect program, the City covers 75% of the cost, up to $2,000, to unhook foundation drains from the sanitary sewer. The new setup is a sump pump that discharges onto your lawn. It also pays up to $70 for downspout disconnection and up to $200 to redirect a pump. Check barrie.ca for current terms.
A crack injection takes about half a day. An interior drainage system usually takes two to four days, and exterior waterproofing three to seven, depending on wall length and what's in the way, like decks or a driveway. You can stay in your home the whole time, and we clean up each evening.
Yes. Most of our repairs carry a transferable lifetime warranty, so it moves to the next owner when you sell. Buyers and home inspectors in Barrie always ask about past water, and a transferable warranty with photos of the repair answers the question before it turns into a price cut.
Send us a note about where the water shows up. We book the free 50-point check, walk the outside and the inside, and give you a written price before anyone picks up a shovel.
