How do I prevent my basement from getting wet?

Protecting your basement from water leaks or flooding starts with identifying water intrusion sources and installing a high-quality basement waterproofing system. Your system should be tailored to your home's individual needs and may include waterproofing products such as an interior drainage system and sump pump. Learn more about how you can prevent water in your basement.

How can I make a damp basement dry?

When it comes to keeping your damp basement dry, installing a dependable basement waterproofing system is key. An interior drainage system and sump pump work in tandem to keep water out of the basement and away from your foundation while a dehumidifier keeps the air dry and prevents condensation from forming on walls, ceilings, and windows. Learn more about how to make a damp basement dry.

How do I fix a leaky basement foundation?

There are many foundation waterproofing methods and products available to prevent water intrusion. However, most water problems can't be solved with a single product or treatment. Working with a reputable waterproofing company is the best way to ensure the basement waterproofing systems that best suit your specific needs are installed. Learn more about how to fix a leaky basement foundation.

How do I get rid of mold and musty odors in my basement?

Mold and mildew thrive in dark, moist environments where organic materials are present, such as a basement or crawl space. Fixing water leaks and protecting against future moisture intrusion with a reliable waterproofing system, as well as keeping the air dry with a dehumidifier, prevents mold growth and odors in your basement. Learn more about how to get rid of mold and musty odors in the basement.

How can I warm up a cold basement?

You can make your basement feel more comfortable and reduce your home heating and cooling costs by insulating your basement. There are many different types of basement insulation to choose from, each of which offers different benefits. Learn more about how to warm up a cold basement.

Sump Pump Upgrade in Verdun

Mr. Paquin in Verdun, Quebec called us because he needed an upgrade for the 10-year-old sump pump system in his basement. He was looking for a system with a backup battery in case of a power failure. We offered to come by for a free inspection and our specialist Patrick went by to check things out. After assessing the situation, Patrick decided that the best course of action would be to install a new drainage system. Our experts first installed a TripleSafe™ Sump Pump System to drain the water from the basement. They then installed a LawnScape™ discharge line outlet system at the end of the buried discharge line. Finally, our experts installed an IceGuard® Sump Pump Discharge Line System to prevent water from flowing back into the home, even if the discharge line is coated in ice or snow.

Installation of WaterGuard and SuperSump Systems in Delson, QC

Problem Our client in Delson, QC, had persistent water infiltrations within their basement, despite the presence of a sump pump. Following a detailed and free inspection, our specialist Patrick noticed that the existing drainage system faced major issues. Firstly, the discharge lines were obstructed by the soil. Secondly, the pump was constantly functional, indicating its inadequacy in dealing with the infiltrated water. Solution Our team installed the WaterGuard interior drain system along the perimeter of the basement. This patented system is designed to prevent clogging. Moreover, it is straightforward and quick to install, unlike French drains that require excavation. Next, we implemented the SuperSump sump pump system, including two distinct pumps. These pumps will evacuate any infiltrated water, even during a power outage, as the second pump operates on battery power. Finally, we installed a new discharge line, connected to the pump, to direct the water outside.

The TripleSafe includes 3 pumps, one of which is battery operated in case of a power failure. It's our most efficient sump pump system and gives you the peace of mind. We connected our Sanidry Sedona dehumidifier to it to control the level of humidity in the basement.
