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
November 30, 2025
When your sewer line fails, traditional open-dig replacement means weeks of disturbance across your yard, driveway, and landscaping. Trenchless sewer replacement—also called no-dig sewer repair, cured-in-place pipe (CIPP), or trenchless pipe rehabilitation—uses just two small access pits to install a seamless new pipe inside the old one. At McDowell Drain & Waterproofing, we’re leaders in Basement Waterproofing Service in Thorold, preserving properties from Port Robinson to St. Johns Chapel while delivering durable, cost-effective solutions.
● Minimal Excavation & No-Dig Technology: On streets like Front Street, Ormond Street, and along the Welland Canal, there’s little room for long trenches. Our no-dig pipe repair only needs two 2'×2' pits, keeping your lawn, gardens, and driveway intact. Check out our clogged drain services in Thorold for added protection.
● High Water Table & Canal Proximity: Thorold’s proximity to the Welland Canal and surrounding wetlands means a high groundwater table. A cured-in-place pipe liner withstands hydrostatic pressure better than patch repairs or spot fixes.
● Rapid Turnaround: Most trenchless sewer replacements Thorold complete in 6–8 hours, compared to days or weeks for open-dig methods—ideal for busy families and local businesses.
● Tree-Root Intrusion Solution : Fewer trucks, less soil removal, and minimal restoration translate to lower carbon footprint and reduced labor costs—often 30–60% less than traditional methods.
● Preserve Historic & Community Character: In Old Town Thorold, where heritage homes and community gardens abound, trenchless methods protect stone walkways and decorative landscaping from damage.
We begin with a high-definition sewer camera inspection in Thorold to locate damage—root intrusion, cracks, or corrosion—and measure the run’s exact length.
Two compact pits are dug at the start and end of the damaged section, preserving your yard and underground utilities.
An epoxy-saturated, fiberglass-reinforced liner is inverted into the host pipe using air or water pressure. Heated water or steam cures the liner into a seamless new pipe.
A follow-up drain camera inspection confirms a perfect seal. We backfill the pits and restore concrete or landscaping—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.
We use advanced cured-in-place pipe systems for jointless, leak-proof repairs.
