A water heater installation that is done incorrectly from the start creates problems that can follow you for years. Improper connections lead to leaks.

Grant installed our water heater a few years back, so I called him when we needed work done recently. He is very knowledgeable about the work he does, and he likes to make sure you are good to go before he leaves!

The installation process starts before we even arrive at your home. When you call us, we ask about your household size, your current unit, your fuel source, and your hot water usage patterns. That information helps us guide you toward the right size and type of unit for your home so you are not overpaying for capacity you do not need or undershooting and running out of hot water constantly.
On installation day, we begin by safely shutting off the fuel or power supply and water lines to the existing unit. We disconnect and remove the old water heater and inspect the surrounding connections, supply lines, and drain setup before installing the new unit. We connect the new water heater to your existing supply and drainage lines, secure all fittings, and verify that the temperature and pressure relief valve is properly installed and functioning. Before we leave, we bring the unit up to operating temperature, check for any leaks at all connection points, and confirm that hot water is reaching your fixtures at the correct temperature.

Water heater installations in South Carolina typically require a permit, and the work must meet local code requirements for Goose Creek and the surrounding area.

We take care of it.
A properly installed water heater runs more efficiently, lasts longer, and causes far fewer problems over its lifetime than one that was installed with shortcuts.

We work cleanly, communicate clearly, and make sure everything is working correctly before we consider the job finished.
