KEEP YOUR FAMILY HEALTHY

You should hire a professional to do waterproofing to keep mould and mildew away from your family, pets, and belongings. Mould thrives in wet, dark places. If someone in your family is suffering from unexplained sickness such as fatigue, morning joint pains, nausea, and headaches, the culprit is most likely mould.

PROTECT YOUR PROPERTY

If your home floods as a result of poor drainage, you may get problems with your home insurance provider. Your belongings, including fabrics and metal, wooden, and paper belongings, are also at risk when your basement is damp. You should hire a professional to test your drainage system, such as testing your sump pumps, because flooding and water damage can cause structural integrity issues. Examples of these are foundation cracks and uneven settling.

SAVE MONEY ON HEATING AND WATER BILLS

If your basement is damp, it will always stink, no matter how many times you clean it. A damp basement also makes the heater go on overdrive to maintain warm temperatures. Basement waterproofing will help you lower your heating bills. Addressing leaks also helps you conserve water and save money in the process.

GET PEACE OF MIND

When you hire us, you will get peace of mind knowing that your property and family are protected. For most Innisfil, ON residents, a home is the biggest investment they will ever make.

Frequently Asked Questions About Basement Waterproofing in Innisfil

Costs vary depending on the scope of work and home layout. On average:

  • Exterior waterproofing: $100–$300 per linear foot
  • Interior waterproofing: $70–$350 per linear foot
  • Foundation crack repair: $1,600–$3,200 per crack
  • Sump pump or backwater valve installation: $1,000–$3,500

We provide free on-site inspections and detailed quotes tailored to your property.

Yes. Direct Waterproofing is fully licensed and insured across Ontario. Our work complies with the Ontario Building Code, and our technicians are trained in safe, long-lasting waterproofing techniques suited for Innisfil homes.

It depends on your home’s structure and the source of water intrusion:

  • Exterior waterproofing prevents water from reaching the foundation.
  • Interior waterproofing manages water after it enters and is ideal for finished basements or hard-to-excavate areas.

We’ll assess your property and recommend the most effective option.

While Innisfil doesn’t currently offer a local rebate program, homeowners may still qualify for Ontario-wide flood prevention subsidies or insurance discounts for:

  • Sump pump installations
  • Backwater valves
  • Foundation drain disconnections

Our team will help you explore any available financial assistance and support you through the application process.

Watch for:

  • Damp basement walls or pooling water
  • Musty odors or visible mold
  • White powder (efflorescence) on concrete
  • Cracks in walls or flooring
  • Rust stains near floor drains or sump pits

These are all early signs of water infiltration or foundation stress and should be addressed promptly.

Yes. We offer emergency waterproofing and flood response throughout Innisfil. Whether you’re dealing with a sudden leak, a failed sump pump, or a flooded basement, our team is available to respond quickly and protect your home from further damage.

Innisfil’s soil can vary from sandy patches to heavy clay. A qualified company understands these local conditions and ensures that any foundation repair is structural and permanent, rather than just a temporary patch that may fail during the next freeze-thaw cycle.

Exterior foundation waterproofing is often considered the "gold standard" because it stops water from ever touching the basement walls. However, interior methods are also highly effective for managing water in finished basements where exterior access is restricted.

With over two decades of service, we have built a reputation based on quality materials and honest advice. Our deep knowledge of local building codes and environmental factors makes us the go-to qualified company for homeowners across Innisfil.

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.

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!

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!
