Turn off the water and power, then call us. A top leak usually points to a loose connection, T&P valve, or inlet fitting. We service and replace water heaters and offer after-hours emergency help. A technician will find the source and confirm repair vs. replacement on site in Nashua and Boston.
Quick steps:
- Close the cold-water shutoff.
- Turn off the breaker or set the gas control to Off.
- Dry the top and watch for active drips.
- Avoid using hot water until inspected.

A water heater leaking from the bottom usually points to a failing tank or a dripping drain valve—shut off the water and power, contain the leak, and schedule service right away. The most common cause is internal tank corrosion from sediment, though a loose drain valve or condensation can also wet the base. If the tank is hot and the leak grows as it heats, the inner liner is likely compromised and replacement is the practical fix. Repair is more likely when the drip comes from the drain valve, T&P discharge pipe, or nearby fittings. Our licensed team regularly handles water-heater leaks across the East Boston area.
If it’s safe to do so, take these steps now:
- Turn the cold-water inlet valve off.
- Cut power: switch the breaker off (electric) or set gas control to Off.
- Catch water and move belongings.
- Do not relight equipment if there’s standing water.
If water is near electrical outlets, keep clear and wait for a technician. <br/> Updated: 2026-03-28 <br/> Need help in East Boston, MA? Call (781) 933-7878 or book online. “Always pleasant, knowledgeable, efficient technicians… I had my water heater repaired in less than 3 hours!” — Phyllis U.

Water heater replacement cost for a 50‑gallon tank is confirmed after an in‑home assessment because fuel type, venting, and required updates vary by home. The biggest cost driver is whether it’s a like‑for‑like swap or a change in gas, electric, or venting that adds parts and labor. If the tank is leaking from the shell or is near the end of its service life, replacement is typical; if problems are limited to controls or valves, repair may be reasonable. Our team replaces many standard 50‑gallon tanks across the Somerville area and can size, install, and remove the old unit.
Here’s what usually affects the final price and timeline:
- Fuel and venting setup (atmospheric vs power/direct vent, gas line and electrical needs)
- Location and access (basement stairs, tight closets, long piping runs)
- Code and safety upgrades (expansion tank, drain pan, new shutoff valves)
- Add‑ons or changes (recirculation, mixing valve, water‑quality protection)
Request an on‑site estimate to confirm scope, parts, and a firm price before work begins. <br/> Updated: 2026-03-14 <br/> Need help in Somerville, MA? Call (781) 933-7878 or book online.

DIY water heater installs are possible, but they are not recommended for safety or reliability. Installation requires correct sizing, venting, gas or electrical connections, and leak testing. Our licensed technicians handle tankless and combi boiler installation, replacement, and startup, and they provide right‑sizing recommendations. We also offer descaling and ongoing service to keep efficiency up. Service is available across the Boston–Cambridge area after an on‑site evaluation. <br/> Updated: 2025-12-21 00:00:00 <br/> Need help in Brookline, MA? Call (781) 933-7878 or book online.
