FOUNDATION REPAIR & BASEMENT WATERPROOFING

Leak Seal Waterproofing in St. Catharines & Niagara

Leak Seal Waterproofing delivers dependable, professional solutions to safeguard homes and commercial buildings from costly water damage. Our team specializes in foundation sealing, crack repair, and comprehensive moisture control, using advanced, proven techniques to identify and stop leaks at their source.

Every property has different soil conditions and drainage challenges, so we provide customized waterproofing plans built around your building — and a proper inspection before we recommend repairs. With a focus on quality workmanship, durable materials and long-lasting results, your property stays dry, secure and protected through every season.

Foundation problems usually come from soil movement, water damage, poor drainage or age. Cracks in walls or floors, uneven or sloping floors, doors and windows that stick, and bowing or leaning basement walls are all signs worth a call.

I bought a house in January and the foundation was severely deformed due to long-term water leakage.  I was in shock and almost broke down when I opened the basement drywalls. I am so lucky that I found Murray Excavating, they saved me and my house. Murray is very professional, he has rich experiences with foundation problems. Murray and his team only took 1 week to completely solve the problems. Now my foundation walls are straight and my basement is dry as a bone. I’d like to recommend Murray Excavating to all the house owners, they will save your house, your time and your money.

Can't say enough about Murray. He was so kind to talk my husband through our walk out back up.... Several times. He encouraged us to call back as we dug and solved our plugged drain issue. He took his time and encouraged us to do it ourselves and would not take a consult payment. He is honest and knowledgable. Thank you so much!
