What usually
turns out to be wrong.
A water heater sits where three services meet, and that overlap is where most bad installs come from, because whoever sets the box doesn’t always own the gas line or the venting. We take all of it. The unit is sized for how the house actually uses hot water, the gas line is sized for the appliance rather than inherited from the one before it, the vent is run to the maker’s requirement, and the old tank leaves on our truck.
Rusty water, or a wet ring on the floor
Brown water at the hot tap only, or damp appearing at the base and drying between showers. By the time either shows, the lining has gone and the steel is rusting from the inside, and no part sold changes that.
The hot water runs out too fast
Usually sizing and recovery rather than a fault. A tank chosen for the house as it was doesn’t stretch to a new bathroom, and sediment on the floor of an older tank steals capacity as well.
Replacing on your schedule, not the tank’s
A tank changed by choice is a morning’s work in a dry basement. A tank that fails first takes the floor covering, whatever was stored beside it and the rest of your week, and it never happens in July.
You want tankless, unpriced
A tankless unit needs a bigger gas line, its own vent to an outside wall and somewhere for condensate to drain. Those three decide the cost, not the box. We price them with the unit.
The furnace was upgraded and the tank was left
A high-efficiency furnace vents out its own side wall and stops sharing the chimney, which changes what the tank beside it is working with. We check the draft at the hood first, because that decides what can go back in.
It now sits over finished space
Basements get finished around water heaters. Where the unit stands over or beside living space, it wants a pan and somewhere for that pan to drain, and both are far easier fitted while the old tank is out.
What the job includes.
The old unit out
Gas isolated, tank drained down, disconnected and carried out, including back up the stairs it came down, and taken away rather than left in the driveway.
The gas line, sized for the unit
A tankless heater draws far more than the tank it replaces. We size the line to the new appliance and run new pipe where the existing one can’t carry it.
Venting
Vent run and terminal fitted to the unit’s own requirement, sealed where it passes through the wall, and kept clear of windows, doors and where snow banks up.
Water side and valves
New connections rather than reused ones, isolation valves so the next service doesn’t mean draining the house, and a drain pan where the unit sits over finished space.
Commissioning
Filled, air purged, lit, temperature set, every joint leak-checked, and a draft and carbon monoxide check taken with the unit running before we hand it over.

Water Heater Installation questions.
If yours isn’t here, the phone is the fastest way to have it answered, seven days a week.
The building usually decides. A tankless unit needs a larger gas line than the tank it replaces, a side-wall vent and somewhere for condensate to drain, so in a house where all three are close by it’s straightforward. Where the run crosses the whole basement, the cost sits in the line rather than the box, and a tank can be the better answer.
Before the cold snap.
Describe the fireplace that won’t light or the water heater on its last tank, and we’ll tell you what the fix takes.
