As we employ a diverse team of plumbing and sewer specialists, we can offer expert service inside and out, inclusive of installation of new sewer lines and sewer repairs.

Water Heater Installation and Repair

Water heater repair and water heater installation are often put off, mostly because water heaters last for such an extended period of time without issues they are easily taken for granted. However, calling GS Custom Plumbing for service sooner rather than later can save you time and money on water heater services.. Hot water is something we often take for granted till we are without it. We have up front pricing and knowledge of codes of water heater installation, repair, and maintenance. Our plumbing technicians can provide fast service for all major brands and types of water heaters, including tank, electric, power vent, and tankless water heaters. Is your water heater not staying lit? We can help with that too. We also install and service all types of commercial water heaters.

Drain Cleaning Repair and Replacement

If you have a clogged drain, you should call for drain cleaning services. At GS Custom Plumbing, we not only remove clogs but also replace old drain when necessary. With our drain cleaning services, we can prevent problems from recurring in the future.

Plumbing Code Violations and Condo Conversions

All properties are subject to plumbing code violations, which can be issued for a number of reasons. For commercial buildings, plumbing code violations are typically received during routine inspections, building renovations, and based on complaints lodged against older buildings.

Water Supply Repiping

Re-piping typically involves the complete replacement of the water distribution pipe system in your home, including pipes, pipe fittings, stop valves, and supply lines.


Water leaks are most often revealed by unusually high water bills. Your water leak could be as minor as a running toilet or could be more serious like a leak under the foundation of your home. If you suspect you have a water leak, call today. Early detection and repair of water leaks is essential to saving on costly home repairs, especially when dealing with a slab leak. Foundation leaks can cause erosion, leading to additional stress and damage to the building structure.

We will help diagnose and repair the problem. Once we’ve pinpointed the source of your leak, we can make repairs quickly. We offer up-front estimates, so you know the cost in advance of work being started.

Gas Line Installation and Repair

Whether it be replacing old gas lines or installing all new gas pipe systems for your entire home, we do it all. If you smell gas you should first and foremost get out of the home. If possible and you are familiar with your meter, shut off gas to your home. Call GS Custom Plumbing as soon as possible. We will work hard to keep you safe and get your life and home back in order.
