Close the main shutoff, kill power to anything the water can reach, and stop using every fixture in the house. A person answers this phone at 2am, and we will walk you through it while we are on the way.

A plumbing emergency is a race against water. Every minute the supply stays open is more drywall, more flooring, more insulation, and a longer conversation with your insurer - which is why the first thing we do on an emergency call is walk you to your shutoff over the phone before we talk about anything else. If you do nothing else on this page, go find that valve now, while the house is dry, and make sure it turns.
The calls arrive on a schedule you could set a calendar by. Hard-freeze nights in January and February bring split copper in garages, crawlspaces and the outside wall of a kitchen sink cabinet. Heavy spring rain brings sump pump failures and surcharged mains in Orange and Liberty Township basements. Water heaters fail whenever they feel like it, though a tank that has been rumbling since Thanksgiving usually chooses the coldest week of the year. Thirty years in these neighborhoods means we know which of those is happening before we pull into the driveway.
When you call, you get a person, not a phone tree routing to a franchise dispatcher three states away. We'll call you back within 15 minutes. We will tell you what to shut off, what a realistic arrival window looks like, and what the work is likely to cost before anyone is dispatched. That last part does not change because it is late - the price is agreed before work starts at 2am the same as it is at 2pm.
What we do

Split copper and cracked PEX in garages, crawlspaces, attics and exterior walls - central Ohio's freeze-thaw swings do this every winter. We isolate the section, repair or replace the failed run, pressure-test it, and then talk about why that pipe froze: an uninsulated run, a cold-air path from a garage, or a line that should never have been in an exterior wall to begin with.

Sewage coming up in a basement is an emergency in the health sense, not just the plumbing sense. Stop using water anywhere in the house - every flush and every load of laundry adds to what is coming up - and call. We clear the lateral, confirm flow, and camera the line once it is open so you know whether it was a blockage or a broken pipe.

A tank sitting in a spreading puddle has failed and cannot be repaired. Shut the cold inlet at the top of the tank, kill the gas valve or the breaker, and call. Most no-hot-water calls are back running the same day, and a full replacement can usually happen the same day too - which matters when the alternative is a weekend of cold showers.

This one is not our call to take first. Leave the house, do not touch light switches, garage door openers or your phone until you are outside, and call your gas utility's emergency line from a neighbor's driveway. They will make the property safe. Once they have shut it down, we handle the repair, the pressure test and the permitted reconnection.
Common problems
Symptoms homeowners call us about, what tends to be behind them, and how we approach the fix.
Usually caused by
Close the main shutoff first - that is the whole ballgame. If water is anywhere near outlets, a panel or a furnace, kill those circuits too. Then call. We isolate the failed run, repair it, pressure-test, and tell you honestly whether this is a one-off or the first of several.
Usually caused by
We check the simple things first, in order, because more than one no-water call has ended with a valve someone closed and forgot. If it is frozen, we thaw it safely and look for why it froze. If it is a failed PRV or a broken service line, you get the diagnosis and the price before we start digging or cutting.
Usually caused by
Stop all water use in the house immediately, keep people and pets off the affected floor, and call. We clear the lateral, confirm flow with water actually running, and camera the line so you know whether you have a maintenance problem or a pipe problem. We stop the water - restoration and drying is a different trade, and we will tell you who to call.
Usually caused by
If the pit is rising, a wet vac or a utility pump buys you time until we arrive. We replace the pump, check the check valve and the discharge, and if this is the second outage-related flood in that basement we will make the case for a battery backup rather than waiting for the third.
How it works
Four steps, no surprises. The price is agreed before anything is opened.
Not a call centre, not a queue. We ask where the water is, whether it is still running, and whether anything electrical is near it. We'll call you back within 15 minutes.
Before anything else, we get the water stopped. Main shutoff for a burst line, the cold inlet for a water heater, the angle stop for a fixture, the breaker for anything electrical near the water.
You get an honest window rather than a comfortable one, and the price for the work before we start it. That does not change because of the hour on the clock.
First we stop the water. Then we make the permanent repair, pressure-test it, and tell you what caused it - so the same pipe, pump or valve is not the reason we meet again next winter.
Reviews
Five-star reviews from Powell and the surrounding suburbs, unedited.
“Keith has done several jobs for us on multiple occasions. He has been available in the evenings as well as on Saturday mornings when it was an emergency. On one occasion, after finishing the job at our house, he willingly walked over to my neighbor's house to help her with her toilet that had broken and was able to fix it right on the spot. He is beyond generous and always informative about the problem at hand. He will tell you what you SHOULD spend our money on and what isn't necessary. I love this about him! I continue to recommend him to everyone I know.”
