Water Heaters & Water Systems

Hot water on demand, steady well pressure, and water you actually want to drink.

Water Heaters and Water Systems
The short version

What to expect

Water systems get ignored until they embarrass you in front of houseguests. A tank that quits, a pump that short cycles, iron staining in a new white sink. We handle the whole chain from the well casing to the shower head: pumps, pressure tanks, treatment, and every style of water heater made. Before we quote a replacement we look at how much hot water your household actually uses and what your well water actually contains, because guessing on either one is how people end up with an expensive unit that still runs out during back-to-back showers.

Water Heater Installation and Replacement

Water Heater Installation & Replacement

Cold showers are a scheduling problem, not a lifestyle. We size and install gas, propane, oil, and electric water heaters, haul the old unit away, and bring the venting up to current code.

Heat Pump Water Heaters
Installation

Heat Pump Water Heaters

Hybrid units pull heat out of the surrounding air and cut water heating costs sharply. We handle placement, condensate, clearances, and the rebate paperwork that makes the payback math work.

Tankless Water Heaters
Installation

Tankless Water Heaters

Endless hot water from a unit the size of a carry-on. We spec the flow rate your household needs, run the gas and venting correctly, and set the descaling schedule that keeps it running for years.

Well Pumps and Pressure Tanks
Service or replacement

Well Pumps & Pressure Tanks

Sputtering faucets and short-cycling pumps are warnings, not quirks. We service and replace submersible and jet pumps, tanks, and controls so the well delivers steady pressure through the season.

Water Treatment and Filtration
Test, then install

Water Treatment & Filtration

Hard water, iron staining, sulfur smell, arsenic, radon. We test the water first, then install softeners, neutralizers, and filtration sized to your well's actual chemistry rather than a catalog guess.

Softeners, valves and trim

A softener set installed under the stairs, then the fixture side of the same trade: faucets, shower valves, and sinks left clean enough to photograph.

No heat? No water? Call now.

Frozen lines, failed boilers, and burst pipes do not wait for business hours. Neither do we.
