"Very easy to make appointment.
Josh showed up and was very polite.  I explained the situation that a home inspector had found some water near the water pump and that we had to have the "leak" repaired as part of the home sale.
Josh wiped down all the pipes and watched for leaks for five minutes and determined that water on the floor and pipes was due to condensation.
The woman answering the phone had actually asked me if it was just condensation when I called to make the service call but told her we had to have someone come out to inspect.
Used Angie's List coupon.
Josh was great, super polite and explained everything he was doing.

Plumbing questions, answered by experts

Homeowners frequently underestimate local permit approval timelines during peak spring and summer construction seasons. Plan for delays if your contractor discovers failing galvanized steel or clay pipes that require full replacement. Excavation for underground plumbing takes longer due to heavy clay soils and strict 60-inch frost depth rules. Finally, account for WI hard water conditions by installing treatment systems to protect the lifespan of your brand-new fixtures.

Helpful?

Successful plumbing requires strict adherence to the 60-inch frost line depth for exterior pipes. You must address local groundwater hardness, which causes rapid mineral scale buildup inside fixtures. Contractors must account for clay-heavy soils that shift during freeze-thaw cycles and stress underground sewer laterals. Always ensure proper winterization, like adding insulation in unheated spaces, to prevent freezing during severe Waterloo winters.

Helpful?

Watch out for quotes missing a state license or skipping local permits. Unpermitted plumbing causes serious resale and insurance problems for your home. Avoid contractors who ignore the 60-inch WI frost depth requirement for underground lines. Finally, reject vague plans that fail to assess existing clay or galvanized steel pipes in older properties before starting any new work.

Helpful?

Flush your water heater annually to remove heavy mineral scale caused by hard groundwater. Schedule periodic camera inspections for aging sewer laterals prone to root intrusion and soil shifting. Test your sump pump every year before the spring thaw to handle seasonal precipitation. Before winter hits Waterloo, inspect pipe insulation in unheated spaces and monitor your water service line for stress from municipal pressure fluctuations.

Helpful?

A passed inspection from local officials provides the clearest proof of correct plumbing. Thorough professionals document that exterior water lines reach the required 60-inch depth. Request pressure test records for new drain and supply lines before contractors close the walls. You should experience zero slow drains, gurgling, or sewer odors, which confirms proper venting. Finally, ensure your contractor documents all pipe materials used for future WI hard water maintenance.
