Is that leak under your sink coming from the disposal or the drain connections? This common question brought our Keep Smiling plumber to a Lawrenceville kitchen for answers. Call now to schedule your under-sink inspection. We installed a brand new half horsepower InSinkErator disposal and also set up a customer-supplied Kohler toilet in the half bath. Every connection was tested thoroughly to confirm zero leaks and proper operation. Since 1985, our licensed plumbers have been going the extra mile to keep Georgia kitchens and bathrooms running smoothly.
