Wet Basement Repair Toronto
A wet basement is rarely caused by just one thing, it’s often a combination of factors working against you at once: poor drainage, an aging foundation, and groundwater pressure all compounding into a chronically damp space. Aquatech’s wet basement repair addresses the full picture, not just the most obvious symptom. If your issue is a single foundation crack rather than a broader wet basement problem, our basement leak repair service may be the faster, more targeted fix. Contact Aquatech for a free assessment to find out which applies to your home.
How Much Does It Cost to Fix a Wet Basement?
Wet basement repair costs typically range from $1,500 to $15,000, depending on the size and complexity of the job, a single problem area costs far less than a basement with multiple water entry points or one requiring a combination of interior waterproofing, exterior work, and drainage improvements. A proper inspection identifies exactly what your basement needs, so you’re not paying for more than the problem requires. Contact Aquatech for a free, itemized quote.

Rated 5 out of 5 starsMy basement sump pump room wall just below my outside stairs and veranda were wet when we had more than 1 inch of rain. I called Aquatech Basement Waterproofing, and assigned Eric to meet me and assessed the work to be done and provided a very reasonable quote, and the work was scheduled to meet my schedule. There were 2 crews of 2 men all from Ukraine, all very knowledgeable, professional and did a wonderful job. They protected the flooring from the my main doorway right down to the basement room where the work was being done. The first 2 man crew removed the Styrofoam from that was on the basement walls and ceiling, moved my battery backup sump pump and moved to a safe locatiion while working in a small area. They broke the concrete floor around the room down to the footings, which needed to be to add weeping tile. They cleaned the area as they worked, removed the concrete debris and then brought in the required material to install weeping tile. The second crew assisted with the installation of the waterproof membrane on the walls, install the weeping tile and cementing of the part of the floor where the weeping tile was installed and added to the sump pump basin. They reinstalled the light and light switch, wall plug outlet. This all was done in a few hours. I would highly recommend Aquatech as their staff are very knowledgeable and very efficient in doing their job. I would definitely use them again if I have any future for any basement Waterproofing, or water issues. Thank you so very much Dianne P. The were very professional s advised that I ca Eric came by promptly, assessed the situation, gave me a quote, very reasonable and scheduled

Rated 5 out of 5 starsThanks to Andrew, Will, Vasyl, and Yuriy of Aquatech Waterproofing, I no longer panic when the weather forecast calls for rain. The four-man team applied interior waterproofing to a large portion of my basement in less than seven hours. They placed Dimpleboard on the walls, installed and covered new four-inch plastic weeping tile pipe and also backfilled, cleaned and cemented the entire work area. The crew was courteous, on time and professional. Company representative, Nico, who appraised the job before the work began, was also very knowledgeable and kindly answered all my questions. The cost was extremely reasonable and I have a transferable life-time warranty for their services. I highly recommend them.

Rated 5 out of 5 starsAquatech Project Consultant Richard responded ultra-quickly to my call for an estimate on 2 cracks on the inside of my basement foundation wall, visible only after I removed panelling & insulation & only when it rained heavily & water was pouring through those 2 small cracks. Richard impressed me with his assessment expertise & the speed at which he provided the best quote & solution for my leaks & my budget as a retiree on a fixed income. The repair on the outside wall with weeping tile replacement & utilities locates was scheduled & communication with Rita in the office & follow up with Richard was excellent. The day of the repair, Water Proof Technicians Vasyl & Yuriy arrived on time & ready to work. They were totally professional, polite & prepared with expertise & the right equipment to complete the task. They impressed me to no end with their work ethic & support for each other rotating in & out of the trench to get down to the footings. They installed the new weeping tile, cleaned the foundation wall & revealed 2 very long cracks which they V cut and repaired with hydraulic concrete. The rest of the process was their standard applications of Aqua Block, fibreglass mesh, another layer of Aqua Block, a layer of Poly-tarp, & a Dimpleboard membrane installation. They back filled the trench & cleaned up the area to perfection. Aquatech is blessed to have Vasyl & Yuriy as employees – thorough & meticulous. They are 12 out of 10 in my opinion!!! Note: 2 of my neighbours were impressed & asked for Aquatech’s phone number from me. Thank you Richard, Rita, Vasyl & Yuri.

Rated 5 out of 5 starsAquatech consultant, Shawn McGirr, investigated my water problem and provided a realistic and cost effective solution. A few days later Bob and Alex arrived to do the work. They both worked very hard and were efficient and clean. They completed an incredible amount of work in a very short period of time and left the worksite as clean as it was before they arrived. I’m confident that the issue has been resolved and comforted by the lifetime warranty.

Rated 5 out of 5 starsAlex, Eugene, Mike and Igor did an amazing job with my basement waterproofing project. They were very personable, very hardworking and very efficient. I was very pleasantly surprised how quickly they finished the job. Everything was cleaned up and put back in order when they were done. I definitely recommend Aquatech Waterproofing. From my first meeting with Tony to discuss the project, I could tell they were the right choice
Wet Basement Repair and Municipal Rebates
If your wet basement repair involves a sump pump or backwater valve, you may qualify for a municipal rebate covering part of the cost. The City of Toronto offers up to $2,250 toward sump pump installation, plus $300 for battery backup, under the Basement Flooding Protection Subsidy Program. Peel Region and Vaughan offer similar rebates for backwater valve installation. Since a wet basement often needs more than one fix, it’s worth knowing that crack repair and waterproofing membrane work aren’t rebate-eligible on their own, but if your inspection reveals a sump pump or backwater valve is also needed, Aquatech will flag that opportunity and handle the itemized documentation your application needs.
Why Choose Aquatech for Wet Basement Repair
A wet basement rarely has just one cause, which is exactly why the wrong contractor gets it wrong. Aquatech starts every wet basement repair with a full inspection covering foundation cracks, aging weeping tile, poor grading, and hydrostatic pressure, not a guess based on the most visible symptom. Nearly 30 years of experience since 1996 means we’ve seen how these causes overlap and compound, something a generalist contractor often misses entirely. Every repair is backed by a lifetime warranty, a price match guarantee, and licensed Trades Master oversight on every job site. When the fix needs to actually hold, not just look fixed for a season, that’s the difference real diagnosis makes.

What Causes a Wet Basement?
A yard sloping toward your home directs water straight at your foundation
Groundwater pressure forces its way through any weak point in your foundation
Failing or missing weeping tile
Old or clogged drainage lets water pool against your foundation instead of draining away
Multiple foundation cracks
Several small cracks combined can let in more water than one obvious large one
An undersized or missing sump pump
Insufficient active drainage lets water accumulate faster than it can be removed
Clogged gutters and downspouts
Rater overflowing near your foundation instead of being carried away from your home
Wet Basement Repair Process
Every wet basement repair starts with a full inspection, since chronic wetness is rarely caused by just one thing. From there, Aquatech follows an eight-step process covering diagnosis, repair, drainage, and waterproofing: addressing every contributing cause, not just the most visible one. Here’s exactly how it works.
1. Comprehensive Inspection
We assess your entire basement: walls, floor, drainage, and exterior grading: to identify every contributing cause, not just the most visible one.
2. Diagnosis and Custom Repair Plan
Based on the inspection, we build a specific plan addressing each cause found, whether that’s crack repair, drainage work, or a combination of fixes.
3. Foundation Crack Repair, If Needed
Any foundation cracks are sealed using epoxy injection, restoring structural integrity, not just covering the surface.
4. Drainage and Weeping Tile Correction
Failing or missing weeping tile is repaired or replaced to properly redirect groundwater away from your foundation.
5. Sump Pump Installation or Upgrade, If Needed
If active drainage is required, a properly sized sump pump is installed to handle your basement’s actual water volume.
6. Interior or Exterior Waterproofing, As Required
Depending on the diagnosis, interior or exterior waterproofing is applied to seal out water at its source.
7. Exterior Grading Correction
Where poor grading is contributing to the problem, we correct the slope around your home to direct water away rather than toward it.
8. Final Testing and Walkthrough
The complete system is tested under real water conditions before the job is considered finished, backed by Aquatech’s lifetime warranty.
Why DIY Wet Basement Fixes Don’t Work
A wet basement with multiple causes is exactly the kind of problem DIY fixes fail hardest against, sealing one visible crack does nothing about the other issues still pushing water at your foundation from different directions.
One fix rarely addresses multiple causes: a wet basement with more than one water source needs more than one fix
Waterproofing paint peels and fails: it blocks moisture from the inside but does nothing to address the water still pressing against the wall
Sealants and caulk aren’t built for foundations: they handle small surface gaps, not the sustained pressure a foundation wall experiences underground
Store-bought crack fillers crack again: they don’t relieve the hydrostatic pressure causing the crack in the first place
A dehumidifier treats the air, not the source: it can’t stop water from actively entering your basement
What Are the Risks of Not Repairing a Wet Basement?
A wet basement poses several hazards that can affect both your property and your health. Here are some of the key hazards associated with a wet basement:
- Structural damage to your foundation, walls, and floors
- Mold and mildew growth, with real respiratory and allergy risks
- Damaged flooring, drywall, and belongings Pest infestations drawn to persistent moisture
- Higher energy costs from excess humidity
- Electrical hazards where water reaches wiring or outlets
- A significant drop in resale value at inspection
