  • Dampness or Mold: If you notice a musty smell, mold, or mildew in your home, it’s a sign of excess moisture. 
  • Standing Water: If water collects in your yard or around your foundation after rain, it can lead to drainage problems and ultimately cause damage to your home.

Seasonal Leak Prevention Tips for Oshawa

unnamed (7)

In Oshawa, where weather conditions can vary significantly, it’s crucial to take proactive measures to prevent leaks and water-related damage. Here are some seasonal leak prevention tips tailored to the region:

For Rainy Seasons:

  • Gutter Maintenance: Regularly clear your gutters and downspouts of leaves and debris to ensure they can effectively channel rainwater away from your home. Consider installing gutter guards to prevent clogs.
  • Roof and Wall Inspections: After heavy rains, inspect your roof and exterior walls for any signs of damage, such as cracks, missing shingles, or water stains. Timely repairs can help keep water out.
  • Basement Waterproofing: Consider waterproofing your basement to guard against heavy spring rains, which can lead to basement flooding. This is especially important if you’ve had issues in the past.

For Snowy Seasons:

  • Ice Dam Prevention: Properly insulate and ventilate your attic to prevent ice dams from forming on your roof. Seal gaps and add insulation as needed to maintain a consistent roof temperature, preventing snowmelt and ice dams.
  • Snow Removal Best Practices: When shoveling snow, be mindful of where you pile it. Keep snow away from your home’s foundation to allow melted snow to drain away. Avoid creating piles against exterior walls, as this can lead to water infiltration.
  • Sump Pump Maintenance: If you have a sump pump, ensure it’s in good working condition before the snow melts or the rainy season begins. Regular maintenance can help prevent basement flooding.

By following these seasonal leak prevention tips, you can reduce the risk of water damage, maintain a dry and secure home, and protect your property in Oshawa!

Aquatech was wonderful right from the first contact to having Richard come out and give us a very complete and detailed quote to the two man crew who were here exactly on time and completed the day hours ahead of time. All the locates were taken care of and within a week of contacting them the job was completed. The workman did a fabulous job and were very respectful of our property. They reviewed the scope of the work before they started and asked if we had any questions. When the work was complete it was difficult to see where they had worked and dug the trench. Everything was tidier than before they started. We are very impressed and in a world where household repair companies can be less than favourable, Aquatech stands head and shoulders above any of them. We would highly recommend this company. We also have a life time transferable warranty too. Bravo. We will definitely be telling all the people we know about our wonderful experience. Thank you.

EXCELLENT experience. Andrew was the first one to arrive and was extremely kind and helpful. Igor and Basil joined Andrew a few minutes later and all three of them worked very hard and finished this massive job in one day. These are some of the hardest workers I have ever seen. There were no hassles or surprises and Andrew, Igor and Basil were very skilled and courteous. Also, Nico was VERY flexible with our constant changes of plans and was very accommodating and understanding. An excellent experience all around - could not recommend more highly!

Terry was friendly, fair, and transparent on his work and recommendations. Other bidders could have gouged myself on the price but he was honest. He kept costs downs but the quality was still top notch. He treated our family like one of his own without being “fake” to get the job. He’s as genuine and real as they come.

Slava and his crew did a fantastic job of installing piers and raised our sinking front concrete 4 inches. Very courteous, hard working crew! They hand dig as opposed to other companies that wanted to use a backhoe thus, saved our shrubbery and trees. I would highly recommend Aquatech!

Frequently Asked Questions

The cost to waterproof a basement in Ontario ranges from $3,000 to $15,000 or more, depending on various factors, including the size of the basement, the severity of water issues, and the chosen waterproofing method. Please note that this is a very rough estimate, and actual costs can vary widely based on specific circumstances.

While effective waterproofing can significantly reduce moisture intrusion, achieving 100% waterproofing is challenging. It’s essential to manage water through proper drainage and sealing, but absolute waterproofing may not be guaranteed.

Interior methods are generally less invasive and cost-effective for minor issues, while exterior solutions provide a more comprehensive and long-term solution for severe water intrusion problems. However, the decision between interior and exterior basement waterproofing depends on the situation.

Waterproofing an existing basement involves assessing and addressing existing issues. This may include fixing leaks, applying sealants, installing drainage systems, and possibly exterior excavation and waterproofing, depending on the severity of the problem.

The best waterproofing system depends on specific needs and conditions. Common systems include interior drainage, exterior excavation, and sealants. Consult with a professional to determine the most effective solution for your situation.
