PEX Water Line Installation in Waltham, MA
PEX (cross-linked polyethylene) piping is a modern, flexible, and very popular choice for water line replacement. It resists corrosion, scaling, and chlorine, making it highly durable for most water conditions. Pipes along exterior walls, in unheated porches and in older homes with little insulation are the most vulnerable. PEX can expand and contract without bursting, which is a real advantage when a cold snap hits Waltham. Its flexibility allows for fewer fittings and faster installation.
Copper Service Line Installation in Waltham, MA
Type K copper is a durable option for underground water lines. It resists punctures and lasts for decades. Copper costs more than PEX but is favored by some homeowners. We install copper with proper bedding to protect it. We can also install sleeves where it passes through foundations.

Main Water Line Repair vs. Replacement in Waltham
