Core Trade Capabilities

Comprehensive, licensed solutions for homes and businesses in Malden and surrounding areas.

Emergency Pipe & Leak Repair

Burst supply lines, pinhole leaks in aging copper, and failed shutoff valves don't wait for business hours. We locate the break, make a durable repair with quality fittings — not a clamp patch — and pressure-test the line before we leave.

Galvanized Repiping & Water Line Upgrades

Many Malden and Somerville triple-deckers still run original galvanized steel supply lines that choke flow and shed rust into your water. We repipe units or whole buildings in modern PEX or copper, restoring full pressure floor by floor with minimal wall damage.

Cast-Iron Sewer Stack & Drain Service

Century-old cast-iron waste stacks crack, scale shut, and leak into ceilings. We camera-inspect the line, replace deteriorated stacks and branches with PVC or no-hub cast iron, and handle the permits and inspections so the job passes clean.

Water Heater & Hydronic Boiler Service

Same-day water heater replacement — we confirm the right size, venting, and parts before we arrive, as our customers' reviews attest. We also service and upgrade hydronic boilers, adding freeze protection, zone valves, and glycol treatment to survive the harshest Massachusetts winters.
