Leaky Pipe
Even small drips risk mold or structural damage—especially in Boston’s freeze-prone walls or unheated basements where pipes are exposed.
Locate the leak’s exact source—listen for trickling sounds or check for condensation patterns. For accessible copper or PEX lines, temporary fixes like pipe repair clamps or epoxy putty can buy time. But if the leak is near joints or in a wall cavity, DIY fixes may fail under pressure and delay real repair. Wrap the area with a towel and mark it clearly so future work avoids damaging pipes again.
In older Boston homes, galvanized steel or iron pipes may have internal corrosion causing pinhole leaks. These often appear suddenly after pressure changes—like after a valve is closed and reopened. If multiple leaks emerge across sections, the entire line may need replacement. Ignoring small leaks in floors or under slabs can lead to foundation settlement or mold in confined crawlspaces, especially in humid summers.
Freeze-related cracks worsen quickly once temperatures rise—water expands to fill the crack under pressure. Insulate pipes in exterior walls, attics, or unheated garages with foam sleeves, and keep thermostats stable during cold snaps. If you’re away for more than a day in winter, set heat to at least 55°F. For pipes already frozen but not leaking, use a hair dryer—not a torch—to warm gradually and prevent bursts.
