  • DIAGNOSIS
  • PREVENTING FURTHER DAMAGE
  • SATISFACTION
  • Diagnosis

    Multiple factors can cause water leakage in a basement. One of those causes is rainwater gathering near the foundation and seeping through into the basement foundation and floors.

    Other causes are:

    • Cracks on the basement floors, doors, and windows allowing underground water through
    • Plumbing issues causing the pipes to leak.
    • Dysfunctional sump pumps that are not draining water away from the basement.
    • Poor ventilation in the basement, resulting in excess moisture that condenses into water.

    Each of these problems needs different solutions to be permanently fixed. You need experts to identify those causes correctly; otherwise, your remedial measures could be fruitless. Only professionals with years of experience and extensive knowledge and equipment will be able to determine the causes of the leaks accurately. They are also in a better position to deliver befitting solutions that aren’t trial and error.

  • Preventing Further Damage

    Regardless of the cause, leaks have the potential to cause costly damages if not tackled soon. The best approach is to prevent the damage from happening. If it does, your best solution will be to prevent it from spreading. Prevention will not only save you a lot of money; it will also keep you safe by maintaining the integrity of the property. Proficient waterproofing service providers can prevent damages from happening. Call a team for regular inspections, and they will identify potential problems and solve them before they occur.

  • Satisfaction

    Having a refined team to handle your basement leaks also comes with satisfaction and value for money. Since such issues could damage the foundation and structure of the house, you will rest easy knowing your home is well-protected. You won’t worry about other potential problems like flooding and the financial repercussions they can have on you. You have more time to focus all your attention on other important aspects of your life, such as your career and your loved ones, thus improving your overall quality of life.

How to detect hidden basement leaks in 3 simple steps

  • WALL INSPECTION

    Leaks from the walls are usually some of the hardest to identify unless you pay close attention. However, sometimes the signs will be easy to spot, especially when you have bright colours on the walls. Some of the signs we look for are:

    Chalky substances: The substance, known as efflorescence, is sometimes white in colour. It forms when water reaches the inner walls and dries out, leaving the crystalline substance.

    Discoloration: We also look for staining on the walls as it can also indicate signs of water presence. The stains could be small spots or large ones, depending on the pattern of the damage. The stains are usually caused by acidic water from outside the house. We take care of the problem as quickly as possible to ensure no further damage is done.

    You could also do a simple experiment using foil paper. Seal in aluminum foil and place it on the wall for 48 hours. If you notice moisture on the foil, you’ll know there is moisture on the walls. Contact us the moment you observe this, and we will give you a permanent solution.

  • CHECKING OUT THE COVE AREA

    Increasing moisture could be the first sign that your basement isn’t in optimal condition. In most cases, your basement may be damp and cold if it doesn’t have good ventilation and insulation systems. If you have invested in quality systems that have also been installed correctly, there shouldn’t be extra moisture. If there is, the water could be coming from another place, like the foundation or the cracks on the floor allowing water from the ground to reach inside the basement.

    We will start by inspecting the cove area. This area, where the wall and the floor converge, is susceptible to cracking and allowing water in. Our professionals will look for cracks.

  • LOOK FOR MOULD

    Mould can cause a lot of health issues that range from eye and skin irritation to respiratory tract infections. Different types of moulds produce various types of pores that could have different repercussions. The presence of mould can be identified through a musky smell in the room or dark spots on the walls. We will inspect your basement to determine the type of mould growing there. We will then remove them and ensure they don’t recur.

    It’s not advisable to paint over mould because it will keep spreading as it grows under the paint. Fungi can still be dangerous even if you don’t see them.

  • Trusted Basement Leak Repair Experts in Toronto!

    A basement is prone to flooding, because it is literally the lowest level of a house, sometimes even built underground. Apart from the repairs that will be necessary, imagine also having to get rid of irreplaceable family heirlooms, storage and furniture that were stored in the basement. This is why looking out for basement flooding warning signs is vital to keeping your basement in prime condition. Being well versed in the causes of basement flooding and knowing how to prevent leaks can save you a lot of time and money.

We had a great experience working with Direct Waterproofing on our exterior waterproofing project. Terry, the project manager, was very knowledgeable and took the time to clearly explain the situation and the recommended solution. The estimate was accurate and the work was completed in two days as expected.

The two-person crew arrived on time each day and worked efficiently throughout the project. They were professional and the finished work looks very well done. Overall, we're very happy with how everything turned out. Thank you, Terry and Direct Waterproofing Team!

We recently had waterproofing work done in our basement by Direct Waterproofing, and we’re truly so pleased with the entire experience. Terry Lisevych and his crew were not only highly professional, but also friendly, respectful, and clearly took pride in their work. The quality was excellent, everything was completed on time, and they kept the job site spotless from start to finish.

From the very beginning, Terry was reassuring and took the time to explain everything clearly, which gave us a lot of confidence moving forward. He truly delivered on everything he promised, and the results speak for themselves.

What really stood out was Terry’s knowledge, honesty, and straightforward approach—it made the whole process feel easy and stress-free. It’s clear he genuinely cares about doing the job right.

We’re very grateful for their work and would wholeheartedly recommend Direct Waterproofing to anyone looking for reliable, high-quality service.

Excellent service from start to finish. The inspection was very thorough and the technician answered all my questions patiently. The repair crew arrived on time and worked hard the entire day. They were respectful of my property and made sure everything was clean when the job was finished. After the waterproofing work was completed, the difference was immediately noticeable. Even during strong rainstorms the basement stays completely dry.

We had a great experience with Direct Waterproofing. We contacted Terry on January 5 and he came out the very next morning to assess a foundation crack in our 1980s home. He provided a detailed quote later that same day.

Despite very cold weather and snow to clear, Thomas and John completed the repair on January 19 after the utility lines were marked. They did a great job and left the area clean. Terry provided photos taken throughout the repair and a lifetime warranty.

We also used Direct Waterproofing in 2024 for a window well drainage repair and another foundation crack with the same high-quality service. Highly recommend.

Would highly recommend Direct Waterproofing. Terry and his crew were professional, worked fast and did a great job. Fair pricing for interior waterproofing- sump pump and bench installation. Terry took the time to explain all of our questions. We plan to use them again to install a back flow valve.
Just had the back flow valve installed. Terry and team were quick and professional. We would highly recommend and would definitely use again for any future waterproofing needs!

Direct Waterproofing company was amazing. From the 1st interaction, where Greg came to see my basement leak issue, to final day when it was completed. Greg was able to provide a quote right after he inspected the outside and inside the house. Their price was very competitive. They arranged for the "locate service" by City of Toronto. They came when they said they will come. When they discovered that what was under the porch was not what they at first thought, they quickly came up with a second solution, that was still close to the initial quote. The whole activity was lead by Terry. I don't know who the initial crew was, but second crew was Roman and Walter. They worked very hard, and were super careful and tidy. They dug over 25 feet around the front and side of the house, waterproofed the foundation, added weeping tile and cleaned up really well. They also dug a big hole for a sump pump in a tiny space of the furnace room corner without any issues. Now you can't even tell there is a sump pump there. Terry also came a few days later to do some touch ups! They were awesome! I would recommend them to anyone that is looking for a great experience and good workmanship!

Walter, Roman, Dima, and Terry from Direct Waterproofing did an excellent job on our exterior waterproofing and sump pump installation.

I don’t typically write reviews but I’ve had a few experiences with Direct Waterproofing now and wanted to call Terry and his crew out for their great work. They are efficient, clean, and Terry is very communicative and responsive.

DW completed the exterior and partial interior waterproofing on our semi and they were very respectful of the space in always keeping it tidy and clean. And it was nice to have people show up when they say they would and finish on time. Shortly after, we had an issue with dampness in our basement and Terry came out immediately to check on the issue (turned out it wasn’t related to the waterproofing). So when it came time to filling the cement in, I didn’t hesitate reaching back out to Terry versus looking for a different company to do the work. They were able to fit the job in shortly after I reached out and they’ll be coming by again to help reroute my sump pump line. All in all, I wish all other contractors were as responsive and easy to work with as Terry.
I had a water leakage issue in the basement after every rain for the last 2 years, but never found the root cause. This time I contacted Direct Waterproofing. Terry came in and checked and provided in depth plan on how to fix the foundation crack issue from outside. He was continuously in touch with me all these days and made me feel confident with the choice of solution seeing the cost involved (C$2000). And today, TERRY and his 2 very hard working team mates, JOHN and THOMAS, came in and dig the whole soil almost 7-8 feet, did all the treatment and re-filled everything in just 8 hours. I was there watching the whole process, and I can say I felt very satisfied with the hard work they put into this project. The price was worth it, but most importantly I got peace of mind now. I would highly recommend Terry and his team for any waterproofing work. They are very genuine and will not try to sell you unnecessary services. And they also give 25 years warranty.

Terry from Direct waterproofing is one of the best professionals I've met. And I don't say it lightly. We needed a sump pump and backup battery pump + discharge pipe.
Terry took the time to brainstorm ideas on where the discharge pipe should go so we don't cycle back the water into our sump pit.

Before installation he took out a lot of garbage that was in the sump pit. He took out plant roots that had grown from underground.

Terry not only installed both pumps and a discharge pipe but came twice and made sure we got everything needed to receive the city rebate.

After each work was done he took the time to clean the debris as well. This is what I call a true professional. You can tell pretty quickly that Terry really cares about the customer. Would highly recommend. 5 stars!

So happy to be able to write another 5 star review for Direct Waterproofing! The team had done some some work for me a couple of years ago (basement inside waterproofing and installing a sump pump - which has been working fabulously!) and while they were here, they applied some concrete parging around my home to seal the area between the foundation and the bottom of the home. Due to weather it had cracked a bit and when I called Terry to see if they could come back and seal it again he was more than willing to help! Although this is a very busy season for them, Terry himself came and did the job. He was so pleasant and thorough and now everything is sealed up before the winter. And … he did it free of charge! I’m very impressed with Terry and his team. Would highly recommend! Thanks!
