Leak Detection and Repiping in Alexandria, IN

The gas-boom-era and early-era homes that make up the bulk of Alexandria's housing stock were built with galvanized steel supply piping in many cases, or with very early copper in others. Galvanized steel corrodes internally over time, reducing the interior diameter and eventually developing pinhole failures at seams and threaded connections. This corrosion also affects water quality, with rust particles and discoloration becoming more common as the pipe narrows. Early copper, while more corrosion-resistant, can develop pinhole leaks at solder joints or where water chemistry has accelerated pitting.

A slow leak inside a wall cavity in an older Alexandria home can go undetected for months, feeding mold growth and structural moisture damage in materials that were not designed with moisture resistance in mind. By the time a wet patch appears on a plaster wall or ceiling, the damage is usually well established. Accurate leak detection limits the demolition required to access the problem.

Leak detection in older construction starts with a systematic isolation process. We monitor the meter for movement with all fixtures off to confirm a supply-side leak is active. Then we use acoustic listening equipment to follow the sound of water escaping through the pipe wall, and thermal imaging where accessible, to narrow the leak location before any wall is opened. In older homes with plaster and lath, limiting access cuts is especially important because the repair is more involved than drywall.

Once the leak location is confirmed, we assess the surrounding piping condition. A pinhole leak in galvanized pipe is rarely isolated; when one section fails, adjacent sections are usually in similar condition. We give you the honest scope: repair the specific failure, or repipe the affected run while the wall is open to avoid returning for the same issue in a neighboring section in a few seasons.

Partial repiping replaces the failed section and any immediately adjacent pipe that shows signs of the same deterioration. This is appropriate when the failure is isolated and the rest of the supply system is in acceptable condition. Full repiping replaces all supply lines from the main to the fixtures throughout the house and is the right choice when galvanized lines are failing at multiple locations or when water quality issues from internal corrosion affect the whole house.

We repipe primarily with PEX, which is flexible, handles freeze events better than rigid copper, and does not require soldering in confined spaces. Copper is also available where code or preference calls for it. We discuss both options and the practical tradeoffs before any work begins.

My water bill jumped but I cannot find a visible leak. What should I check?

Turn off everything in the house and watch the meter for movement. If the meter continues moving with all fixtures off, you have an active supply leak somewhere in the system. Check toilets for phantom flushing first, as they are a common culprit. If toilets are fine and the meter is still moving, the leak is in the piping.

Is PEX appropriate for an older Alexandria home?

PEX is widely used in residential repiping and meets code requirements in Indiana. It handles thermal expansion and freeze events better than rigid copper, which matters in older Alexandria homes that may have supply lines running through unheated spaces. It requires proper support and is not suitable for exposed outdoor runs, but for interior supply distribution it is a practical and durable choice.

How long does a whole-house repipe take?

For a typical older Alexandria home of one or two stories with a normal fixture count, a full repipe usually takes two to three days including access cuts, pipe runs, fixture connections, and pressure testing. Plaster walls take longer than drywall because patch work is more involved. We give you a project timeline and access-point plan before starting.

Will repiping improve my water pressure?

If the low pressure is caused by corroded galvanized lines that have narrowed internally, yes, replacing with properly sized PEX or copper will restore normal flow. If the pressure issue is at the street or meter level, repiping the interior supply will not resolve it. We confirm the source of the pressure problem before recommending interior work.
