McDowell Drain & Waterproofing is a Niagara Region–based contractor focused on solving residential water, drainage, sewer, and foundation problems through methodical assessment and proven construction practices. The company is known for its ability to diagnose complex basement and underground issues that develop due to Niagara’s challenging soil conditions, groundwater movement, and aging municipal systems. With more than 45 years of hands-on experience and over 3,500 residential projects completed, McDowell has built its reputation on consistency, accuracy, and long-term performance. The team prioritizes cause-based solutions, ensuring water intrusion, drainage failures, and sewer issues are corrected at their origin rather than managed with surface-level repairs. This approach has made McDowell a trusted choice for homeowners dealing with persistent or previously unresolved problems. All work is completed entirely in-house, allowing for tight quality control across waterproofing, drainage, sewer, and plumbing services. Systems are selected and installed for durability, with qualifying waterproofing solutions backed by 20-year written warranties. Throughout the process, homeowners receive clear explanations, realistic recommendations, and workmanship designed to protect both the structure and long-term value of their home. McDowell Drain & Waterproofing is relied upon across the Niagara Region for dependable execution, technical competence, and solutions that last—not shortcuts.
