Water Heater Repair for Gardiner Homeowners

Gardiner sits in Kennebec County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for water heater repair gets a technician who already knows the local housing and codes, not a first-timer.
No hot water is never convenient. Aces Highlands diagnoses and repairs water heater issues quickly and accurately — getting your hot water back on as fast as possible.
Common water heater problems include no hot water, inconsistent temperatures, strange noises, leaking, pilot light issues, and error codes on tankless units. Our technicians can quickly identify the problem and recommend the most cost-effective solution. If your water heater is leaking, our leak repair specialists can address any water damage at the same time.
We repair both tank and tankless water heaters from all major manufacturers. Common repairs include thermocouple replacement, heating element replacement, thermostat repair, anode rod replacement, and descaling for tankless units.
If your water heater is leaking from the tank or the cost of repair exceeds half the price of replacement, we will be honest about recommending a new unit — whether that is a traditional tank or a tankless system. We help you weigh the options without pressure.

Gardiner Homes and What They Need
Gardiner's median home was built in 1944, with 47 percent of housing dating before 1940 and two-thirds before 1960 -- among the oldest housing stock of any Kennebec County town Aces serves. Much of it sits inside the National Register-listed downtown historic district, about 7 acres and 47 buildings along Water Street, Cobbossee Stream and the Kennebec riverbank. Exterior work in that district can draw added review, so a heat pump installation near downtown often starts with a conversation about where the outdoor unit can actually go.
Water Supply and Drains in Gardiner
Gardiner draws its public water from the Gardiner Water District's gravel-packed wells, while the city runs its own wastewater treatment plant in South Gardiner. The city sits right where the Kennebec River meets Cobbossee Stream, which drops about 130 feet over falls on its way through downtown -- a dramatic bit of geography that also means older sections of the sewer system have had a long time to age. A camera inspection ahead of any sewer line repair is worth doing on Gardiner's older streets.

Getting to Know Gardiner
Gardiner traces back to 1754, when Boston physician and drug merchant Dr. Silvester Gardiner began developing more than 100,000 acres at the head of navigation on the Kennebec River. The city later built an economy around exporting river ice, packed in sawdust and shipped as far as the tropics, alongside a paper industry that boomed from the 1860s into the 1920s.
Gardiner's entire downtown was added to the National Register of Historic Places in 1980, and the poet Edwin Arlington Robinson, who won three Pulitzer Prizes, grew up here and is still remembered locally. That historic downtown, with its ice-and-paper-era brick blocks, is a big part of why Gardiner's housing stock runs as old as it does.
Local & Independent — Not a Franchise
We are an independent, Portland-based company, not a franchise chain routing your Gardiner job to a call center. Technicians are not on commission, so the recommendation you get is the one your house actually needs. Getting invited back is the only metric that matters here.
How a Tank Water Heater Works
- Cold inlet — the dip tube carries it to the tank bottom
- Burner — heats water at the bottom of the tank
- Anode rod — sacrificial rod that fights corrosion
- T&P valve — releases pressure if it builds too high
- Hot outlet — draws the hottest water from the top

- Most Gardiner homes are on Gardiner Water District water from gravel-packed wells; on a private well, we check the pressure tank and water quality alongside the water heater repair.
- Summit Natural Gas of Maine reaches parts of Gardiner, so a gas water heater is an option on those streets; propane, electric and heat-pump models work anywhere in town.
- The swap is permitted through the City of Gardiner Code Enforcement Office, the relief valve gets a proper gravity discharge line, and any gas connection is made under our Maine Fuel Board license.

We highly recommend Highlands Heating & AC. They are extremely responsive, knowledgeable and do great work. Our boiler stopped working and Elijah was quick to respond after hours on a Friday. He installed a new boiler and heat pump hot water heater.
Water Heater Repair FAQs
Why do I suddenly have no hot water?
On electric units it is most often a tripped breaker, failed heating element, or the high-limit switch; on gas units, a pilot or ignition problem or a failed thermocouple; on tankless units, an error code from scale buildup or a flow sensor. Most of these are quick, affordable repairs.
My water heater is leaking — can it be fixed?
It depends where the water is coming from. Leaks at valves, fittings, or element gaskets are usually repairable. Water seeping from the tank body itself means the inner tank has corroded through, and replacement is the only fix. We will show you exactly which one you have.
Why does my pilot light keep going out?
The most common cause is a worn thermocouple — the safety sensor that holds the gas valve open — which is an inexpensive replacement. Draft problems, a dirty pilot orifice, or a failing gas control valve can also be responsible. It is a fast diagnosis for our technicians.
Why is my hot water rusty or smelly?
Rusty hot water usually means the anode rod is spent and the tank has begun corroding inside; a rotten-egg smell is typically bacteria reacting with the anode rod. An anode replacement and flush often solves it — but rust from an older tank can signal it is nearing the end.
Do you service tankless water heaters too?
Yes — we diagnose error codes, descale heat exchangers, replace flow sensors and igniters, and service all major tankless brands, whether or not we installed the unit.
