“Very happy with the service from Cumming's. There was a water leak from an upstairs source into the ceiling of a the Family Room. John found the source right away (pipe solder joint) and made the repair in an hour. From the call for an appointment to the repair was quick also. Thanks John!!”

Everyday tips & prevention

Four things worth doing before you need us.

Know where your main shut-off is

Before an emergency happens, find the main water shut-off and make sure everyone in the house can reach it. It is the single fastest way to limit damage from a burst line.

Test your sump pump before spring

Pour a bucket of water into the basin and confirm the pump kicks on and discharges. A backup pump keeps working when power or the primary pump does not.

Disconnect hoses before the freeze

A hose left attached over a Michigan winter traps water in the hose bib. That trapped water is a common cause of springtime leaks inside the wall.

Grease belongs in the trash, not the drain

Cooking grease cools and hardens inside the branch line. Over time it collects everything else that goes down with it.
