Unstable, Wet Cold Cellar Solution in King City, ON Unstable, Wet Cold Cellar Solution in King City, ON

A home in King City, Ontario, had a cold cellar beneath the front porch and water was seeping in. There were stored items in the area, and they were getting wet and mouldy. The foundation was cracked and folded inward, creating urgency to fix the problem. The homeowner was dealing with persistent musty odours and was looking for a solution.

The customer called Clarke Basement Systems, and Ben Wallis explained the process of our solution. Jose Martinez and the team installed WaterGuard® Below-Floor Drain, ThermalDry® wall membrane and Geo-Lock™ Wall Anchors to fix the problems. The Customer was satisfied because they didn't just spend money on their house – instead, they invested in the value of their house fixing some significant problems permanently with a fully-transferable warranty that goes with the home if they decide to sell.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your King City home is both an eyesore and a safety hazard. It is also likely to get worse with time, but we can fix it for you!

Our experts use PolyLevel, a superior polyurethane foam to provide reliable concrete lifting & leveling solutions. Small holes are drilled in the concrete and the expansion of the foam lifts & levels the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, requires larger holes in the concrete and does not last as long as PolyLevel.

If your home has cracked concrete steps, pool decks, patios, or other slabs, then NexusPro is the right solution. NexusPro repairs concrete cracks and joints and is ultra-durable, so it will withstand UV rays, extreme weather, and more.

After utilizing our expert concrete repair solutions, consider the powerful concrete sealant, SealantPro. SealantPro further protects your concrete by bonding with it to guard against oil, gasoline, liquids, and other debris. In just one coat, SealantPro extends the life of your concrete by 3 to 5 times overall. 

Call us today to learn more about our proven concrete leveling, cracked concrete repair, and concrete sealing techniques. We also offer professional installation of LintelLift to repair and support sagging, cracked garage lintels.

  • Uneven Patios
