Yes. The chlorine in Marlborough’s treated water accelerates corrosion inside the tank. It eats the anode rod faster, and once the anode rod is gone, the chlorine goes to work on the steel tank shell. Most water heaters in Marlborough last 8 to 10 years — a little shorter than the 10 to 12 you might get on untreated well water. Draining the tank every six months helps.

Sometimes. Condo buildings have shared water shutoffs, shared flues, and HOA requirements about unit type and installation. We’ll coordinate with your association and make sure the replacement meets their specs. We’ve done water heaters in Marlborough condos for decades — we know the buildings and what they require.

Usually. The thermocouple is the most common failure. It’s the sensor that tells the gas valve the pilot is burning, and over time it wears out. We can swap it in about 30 minutes. If the gas valve itself is failing or the burner assembly is rusted — not uncommon in damp Marlborough basements — replacement is the better long-term call.

A standard 40-gallon gas unit runs $1,500 to $2,200 installed. A 50-gallon power-vent runs $1,800 to $2,800. Electric runs $1,200 to $1,800. Condo installations sometimes add cost if the building requires a specific unit or if access is through tight common areas. We quote everything before we start.

Yes. Downtown Marlborough Victorians and older capes often have water heaters shoehorned into spaces that make you wonder how the last guy got it in. We drain them in place, work them through doorways, and get the new one seated. Our guys have done it thousands of times.

If your water heater is eight years old and has never been flushed, the bottom is layered with sediment — even on municipal water. That layer insulates the water from the burner and reduces capacity. A 40-gallon tank with heavy sediment might only deliver 25 to 30 gallons of usable hot water. We can flush it and see if it recovers, or replace it if the tank is too far gone.

The pressure switch that tells the blower the exhaust is flowing may be stuck, or the blower motor relay may have failed in the closed position. A power-vent unit that runs continuously is wasting gas and electricity. We can diagnose it in minutes. If the blower motor is near the end of its life, we’ll tell you whether repair or replacement makes more sense.
