Galvanized and Polybutylene Line Replacement in Trenton
Galvanized steel pipe rusts from the inside, and polybutylene pipe becomes brittle and splits without warning. If your underground service is either material, repairs are often temporary. We replace the line with PEX or Type K copper, often by pulling the new pipe through the old path to limit digging. A new line restores pressure and removes the risk of repeated leaks.

Polybutylene Pipe Replacement in Trenton
Many homes built in the 1980s and 1990s may have polybutylene pipes, which are prone to sudden failure due to their material composition. If you have polybutylene in your underground water lines, proactive replacement is usually recommended. We focus on safely removing and replacing these problem pipes with modern, durable alternatives, preventing future leaks in Trenton.
Underground Pipe Repair Cost Comparison in Trenton, NJ
A single point repair on a shallow water line is the most economical option. Pipe bursting or pulling a new line through the old path costs more but avoids open trenching and long-term risk. Full trench replacement is sometimes needed when the old route is blocked or the pipe is too damaged. We explain each method and its cost so you can choose the best value.
Main Water Line Repair in Trenton
Your main water line runs from the meter box to the house and is under constant pressure. When it leaks, you may notice a spinning meter dial with all fixtures off, low pressure or a wet spot that never dries. We locate the leak, expose the pipe and splice in a new section with approved fittings. If the line is old galvanized or polybutylene, we will recommend a full replacement before more breaks occur.
Underground Sewer Line Repair in Trenton, NJ
Buried sewer laterals crack from root intrusion, soil settling and age. We camera the line to find the exact spot, then excavate and replace the damaged section with PVC. Shielded couplings make a watertight connection to the existing pipe. We confirm proper slope and flow before backfilling and compacting the trench.
Foundation Leak Detection and Repair in Trenton, NJ
Leaking pipes beneath a slab foundation are a serious issue that usually requires specialized underground repair. We use advanced acoustic and thermal imaging to detect slab leaks without destructive testing. Once located, we provide precise repair solutions, from re-routing lines to targeted slab penetration, to protect your home's structure in Trenton, NJ.
