What customers say

“Toilet was overflowing at six in the morning on a holiday weekend. Answered live, arrived in forty minutes, no holiday surcharge.”

Curtis A.Homeowner

“Our main line had backed up twice in six months. This time they put a camera down it and showed me the root ball on the screen. First time anyone had bothered to explain why it kept happening.”

Yvonne P.Homeowner

“Polite, tidy, and he put down covers without being asked. Small thing, but it told me a lot about how the rest of the job would go.”

Questions about tankless water heater installation in Duncan

Will a tankless really give endless hot water?

Endless, yes. Unlimited flow, no. A tankless heats what passes through it, so the question is how many fixtures you run at once. We size to your real peak, which usually means two showers plus a sink.

Do I need a bigger gas line?

Often, yes. A tankless draws far more gas than a tank while it is firing. Skipping this is the single most common reason a tankless underperforms, so we size the supply as part of the job rather than as an extra.

How much maintenance does it need?

A descale roughly once a year in most of Duncan, more often on hard water. We fit isolation valves at install so it is a quick job rather than a teardown.

Are you actually local to Duncan?

We dispatch to Duncan and the surrounding towns every day, and the van that comes to you is the one already nearest your address. That is what keeps the arrival window short.

Will you tell me if something does not need fixing?

Yes, and it happens often. If a repair will hold, we say so rather than selling you a replacement. If a unit is genuinely at the end of its life, we will show you why we think so instead of asking you to take our word for it.
