Leak Detection and Pipe Repair
Water gets everywhere except where you can see it. By the time there's a stain on the ceiling, the leak has been running a while. The goal is to find it accurately the first time instead of opening three walls looking.

Your water bill jumped and you don't know why
Start with the toilets. A silently running toilet is the most common invisible leak in a house and it can waste hundreds of gallons a day.
Put a few drops of food coloring in the tank, don't flush, and come back in fifteen minutes. If color shows up in the bowl, the flapper is leaking and water is running around the clock. That's usually a cheap fix.
If the toilets are clean, shut off every fixture in the house and look at the water meter. If it's still moving, something is leaking between the meter and the house or inside a wall.
What we find
- Supply line leaks — inside walls, under slabs, in crawlspaces
- Drain leaks — often only when a specific fixture runs
- Fixture leaks — faucets, valves, supply lines to toilets and sinks
- Water heater connections
- Failed shutoff valves — the ones that only fail when you finally need them
- Frozen and burst pipes — garages, crawlspaces, and pipes in exterior walls

Washing machine hoses
While we're on the subject of leaks that ruin houses: look behind your washing machine. If those hoses are rubber and more than about five years old, replace them with braided stainless. A burst washer hose puts out water at full supply pressure, continuously, until someone finds it. It's one of the most common large-loss claims in residential insurance and one of the cheapest to prevent.
Winter
Maryland gets just enough hard freezes to break pipes in the places nobody insulated: garages, crawlspaces, exterior walls and unheated additions. Before the first freeze, disconnect and drain your outside hoses — leaving a hose attached is what turns a hose bib into a burst pipe inside your wall.
Wet spot, high bill, or a pipe you can hear?
Shut the main if water is running where it shouldn't, then call.

How do I know if I have a hidden leak?
Shut off everything that uses water and watch the meter. If it moves, you have a leak. A jump in your bill with no change in habits is the other big clue.
Do you cut open walls to find leaks?
Only where we have to, and only after narrowing it down as far as we can. The point of leak detection is to open the smallest hole that solves the problem.
A pipe burst and water is everywhere. What do I do first?
Shut the main off, then the power to any area with standing water. Then call.
Should I replace my galvanized or polybutylene pipe?
Both have known failure histories, and plenty of Maryland houses still have them. Whether to repipe depends on what you've got, how it's holding up and what your plans for the house are. We'll give you a real assessment, not a scare.
Can you fix a leaking outdoor faucet?
Yes — and if it froze and split, we'll also tell you how to keep it from happening again.
