Drain Line Leak Under Foundation in New Haven, CT
Leaks in drain lines under the foundation can be harder to detect because they are not under constant pressure. We use camera inspection and hydrostatic testing to find cracks and separated joints. Repairs may involve tunneling, cutting the slab or pipe lining. We walk you through the trade-offs of each method.

Foundation Leak Repair Cost Comparison in New Haven, CT
Direct repairs are often the lowest upfront cost but involve breaking concrete and may need flooring repairs. Reroutes cost a bit more but avoid concrete work and future leaks in the abandoned line. A full repipe is the most complete option for homes with multiple leaks or aging pipe. We help you compare total costs, including flooring and drywall repairs.
