At Lambton Waterproofing, we’re committed to helping homeowners in Sarnia protect their most valuable asset—their home. With years of hands-on experience in foundation and basement waterproofing, we understand the unique water challenges that come with local soil, weather, and aging homes.
We don’t believe in one-size-fits-all fixes. Instead, we provide tailored solutions that solve the root problem. From small cracks to full drainage systems, every project is handled with care, precision, and a long-term mindset. Our team brings local insight, technical skill, and practical know-how to every job we take on.
We stand behind our work with warranties that give you confidence and peace of mind. Whether it’s interior waterproofing, foundation repair, or drainage installation, our methods are proven, safe, and backed by durable materials built for Canadian conditions.
As experienced professionals, we take time to do the job right—no shortcuts, no rushed jobs, and no guesswork.
