The leak itself is usually invisible, but the signs show up nearby. Look for water staining or soft spots on drywall, paint that is bubbling or peeling without an obvious cause, a musty smell that does not go away, or an unexplained increase in your water bill. In some cases the floor feels soft or the ceiling below shows discoloration before anything is visible on the wall itself. By the time these signs appear, the leak has typically been running long enough to reach building materials beyond the pipe itself.

When water inside a pipe freezes, it expands with enough force to split the pipe wall or blow out a joint. Pipes in uninsulated exterior walls, unheated crawl spaces, and areas near garage doors are most vulnerable. In Central and Eastern Pennsylvania, where temperatures can drop well below freezing for days at a time from December through February, even pipes that have handled previous winters without issue can fail when a cold stretch is severe enough or lasts long enough. Haller’s emergency line is available around the clock when that happens.

It depends on where it is and what it is reaching. A pinhole leak in an exposed basement supply line that is dripping into a bucket is lower urgency than one inside a wall cavity or above a finished ceiling. The risk with any slow leak is that the damage accumulates quietly. Mold can establish in a wet wall cavity within days. If there is any question about what the leak is reaching, it is worth getting a plumber in sooner rather than scheduling it out two weeks.

Most homeowner’s insurance policies cover sudden and accidental water damage but exclude damage from leaks that developed gradually over time. Whether a specific leak qualifies depends on your policy language and how long the insurer determines the leak was active. Haller does not handle insurance claims directly, but our plumbers can document the repair and the condition of the surrounding area, which some homeowners find useful when filing a claim. We recommend contacting your insurer promptly after any significant leak.

An accessible leak on an exposed supply or drain line can often be repaired in a few hours. A leak inside a wall, under a slab, or in a crawl space takes longer because accessing the pipe is part of the work. We assess the access situation as part of the diagnosis and give you a realistic timeline before we begin. Most repairs are completed in a single visit.
