Plumbing Problems We Fix

Drain Cleaning & Clogs

Slow sink, standing water, gurgling drain or a blockage that keeps returning? We clear kitchen, bathroom, laundry, floor and main drains using professional drain-cleaning equipment, with camera inspection when the cause needs a closer look.

Sewer Backup & Main Line Problems

Sewage at a basement drain, several fixtures backing up or recurring main-line problems can point to a deeper blockage. We restore flow and can use a sewer camera when needed to identify roots, buildup, damage or another underlying cause.

Gas Lines & Appliance Hookups

Need a gas line installed, altered or connected to an appliance? Greg’s provides code-compliant gas piping for equipment such as stoves, dryers, fireplaces, BBQs, furnaces, boilers and water heaters.

Toilet Repair & Installation

Running, leaking, clogged or weak-flushing toilet? We diagnose the fixture and connected plumbing, replace failed parts where appropriate and install replacement toilets when repair is no longer the practical option.

Water Heater Repair or Replace

No hot water, inconsistent temperature or water around the tank? We diagnose tank and tankless water heaters and explain whether repairing the current unit or replacing it makes better sense based on its condition.

SUMP PUMPS & BACKWATER VALVES

A reliable sump pump helps manage groundwater while a backwater valve can reduce the risk of municipal sewer flow entering the home. We assess the plumbing conditions and explain which flood-protection work is appropriate.
