How to hire a plumber in Madison

• Check the Wisconsin license. Unlike some trades, plumbing is licensed statewide: the WI Department of Safety and Professional Services issues Master Plumber and Journeyman Plumber credentials. Ask who will actually be at your house and what license they hold — a master plumber's name on the truck doesn't mean a master plumber is doing the work.
• Confirm insurance. Liability coverage plus workers' compensation, with certificates you can see. Water damage escalates fast, and an uninsured mistake becomes your problem.
• Ask about permits. Madison requires plumbing permits for most work beyond simple repairs and like-for-like fixture swaps — water heaters, repiping, new drain lines, sewer laterals. A licensed plumber pulls it as a matter of course.
• Get the price structure in writing. Flat-rate per job or hourly plus parts? Is there a trip or diagnostic fee, and is it credited toward the repair? Ask before they roll a truck, not after.
• Understand emergency pricing. Nights, weekends, and holidays cost more nearly everywhere. Ask what the after-hours rate is while you still have a choice — a burst pipe at 2 a.m. is a bad time to negotiate.
• Ask what warranty covers the work, and for how long, separate from the manufacturer's warranty on the part itself.

Madison plumbing, house by house

Dane County's housing stock spans a century and a half, and what's behind your walls depends heavily on when your house went up. Older homes on the isthmus and near east side often still have galvanized steel supply lines that corrode shut from the inside — low pressure that gets worse year over year is the classic symptom — and cast-iron drain stacks that eventually crack or scale over. Post-war ranches commonly have copper; newer construction is typically PEX.

Lead is a fair question to ask. Madison Water Utility ran a citywide lead service line replacement program that finished in 2012, so the pipe from the main to the house is generally no longer the issue it is in some cities. Interior plumbing is a separate matter — homes built before 1986 can still have lead solder at copper joints. If you're concerned, ask a plumber to look rather than guessing.

Madison's water is hard — the aquifer runs through limestone. That mineral load quietly shortens the life of water heaters, fixtures, and appliances by scaling them up from the inside, which is why softener installation and service is such a routine call here.

Winter, and the calls that come with it

Frozen pipes are the season's signature emergency. The pipes that burst are almost always the exposed ones — crawl spaces, unheated basements, garages, and anything running through an exterior wall. Before the first hard freeze, it's worth knowing where your main shut-off valve is and confirming it actually turns; the middle of a flood is a bad time to find out it's seized.

Spring brings the other half of the cycle: snowmelt and heavy rain push groundwater up, and sump pumps that sat idle all winter get tested hard. Sump failure and basement backups cluster in March and April every year.

Water heaters tend to fail on their own schedule, typically somewhere in the 8–12 year range, and hard water pushes that toward the low end. If yours is past a decade, replacing it on a weekday you chose beats replacing it on the weekend it chose.
