How to Spot (& Fix) Common Plumbing Problems in Your Home
Plumbing problems usually don’t start with a big splash. They begin in small ways — a tap that won’t stop

When your underground sewer line fails in Welland’s varied terrain—from Crescent Park to East Main—the last thing you want is a weeks-long trench tearing up your property. With trenchless sewer replacement, also called no-dig sewer repair, cured-in-place pipe (CIPP), or trenchless pipe rehabilitation, you install a brand-new, seamless pipe inside the old host using just two small access pits. At McDowell Drain & Waterproofing, our trenchless sewer line replacement Welland expertise preserves your lawn, driveway, and landscaping while delivering a long-lasting, cost-effective solution. We also offer basement waterproofing in Welland and sewer camera inspections for complete protection.
● Protects Your Property: Welland’s mix of urban and rural settings—like Canal Bank Street homes and Silvermere country lots—means extensive trenches can damage driveways and gardens. Our no-dig pipe repair method uses two compact 2′×2′ pits, leaving the rest of your property untouched. Learn more about our interior basement waterproofing in Welland.
● Resilient Against High Groundwater: Proximity to the Welland Canal and Lake Erie raises the water table. A cured-in-place pipe liner forms a seamless new pipe that resists hydrostatic pressure—far outperforming traditional spot repairs.
● Rapid Project Completion: Most trenchless sewer replacements in Welland finish in 6–8 hours, compared to days for open-dig. That means minimal disruption to family routines or local businesses along Division Street.
● Eco-Friendly & Cost-Effective : Reduced soil removal and restoration work cut your carbon footprint and often save 30–60% on labor and landscaping costs versus conventional methods.
● Ideal for Commercial & Municipal Applications: Whether it’s a small residential lot or a commercial property off Canal Street, trenchless CIPP lining can rehabilitate pipes up to 48″ in diameter—perfect for schools, hotels, and municipal storm drains.
We start with a high-definition sewer camera inspection in Welland to assess damage—cracks, roots, or corrosion—and measure the exact run length.
Two small pits are dug at the beginning and end of the damaged segment. No trenches, so your driveway and lawn stay intact.
An epoxy-saturated, fiberglass-reinforced liner is pulled or inverted into the host pipe under pressure. Heated water or steam cures the liner in place, forming a seamless new pipe.
We perform a follow-up drain camera inspection to confirm a perfect seal, then backfill the pits and restore your surface—often the same day.
With more than 45 years in the industry, we bring unmatched expertise, hands-on knowledge, and proven reliability to every job.
