Reliable Foundation Repair, Waterproofing & Maintenance for Ottawa Homes
Your home’s foundation is more than just a concrete base—it’s the critical support system that keeps your entire structure safe and stable. Over time, Ottawa’s harsh winters, freeze-thaw cycles, and shifting soil can put your foundation under stress, leading to cracks, leaks, and even serious structural problems.
At L J Masonry & Construction, we specialize in residential foundation repair and waterproofing services in Ottawa, helping homeowners maintain safe, dry, and level homes. Whether you’re dealing with small cosmetic cracks or major structural movement, our skilled technicians have the knowledge, tools, and local experience to diagnose the issue and deliver long-lasting repairs.
We offer a full range of foundation repair and protection services, customized for the unique conditions of Ottawa’s climate and soil.
🔧 Foundation Crack Repair
Foundation cracks are common in Ottawa homes, especially after cold winters or heavy rainfall. But not all cracks are harmless. We provide thorough crack assessments and use high-quality polyurethane or epoxy injection systems to seal both interior and exterior cracks, preventing water intrusion and further damage.
🌧️ Basement Waterproofing
Water in your basement can lead to mold, wood rot, and even foundation failure. We offer interior and exterior waterproofing systems, including weeping tile installation, membrane application, drainage solutions, and sump pump systems. Our goal is to eliminate moisture issues at the source and keep your basement dry all year long.
🏚️ Structural Foundation Repair
If you’ve noticed sloping floors, bowing walls, or doors and windows that no longer close properly, you may be facing a structural foundation issue. We use trusted methods such as underpinning (to stabilize and lift sunken foundations), wall bracing, and reinforcement systems to bring your foundation back to its original level and strength.
⚙️ Sump Pump Installation & Maintenance
A reliable sump pump is your first line of defense against basement flooding. We install new sump pump systems, upgrade existing ones, and offer annual maintenance to ensure your pump is ready for the next big storm or snowmelt.
