Water Heater Installation

Your sinks, washing machine, showers, and bathtubs depend on your hot water heater to perform their essential functions. As part of all of our plumbing installation services, we will perform an initial consultation to discuss your residential property’s needs and requirements.

Water heater installation includes the cost of your replacement water heater and gas line installation, but you may need to consult with your technician about possible permit charges. Oftentimes, homeowners find that their hot water heater has been operating inefficiently for years, quietly running up their utility bills.

There are several different types of residential water heaters currently on the market, including conventional tank water heaters, solar water heaters, and tankless water heaters. Your technician will be able to help you determine the best water heater for your property.

Drain Cleaning Services

Piping Installation

Clogged drains, rusted pipes, leaks, and bursts are nightmares for homeowners, but they’re not the only pipe issues that crop up. When your pipes are installed properly, you can trust that you have set yourself up for a future with minimal headaches and plumbing concerns.

If you are coping with chronic sewer pipe issues, remodeling your home, moving appliances, updating your bathrooms, or adding a second bathroom, turn to Cornerstone for your plumbing installation services today!

How do I tell if I need pipe repairs or repiping?

Your technician will be able to look over your pipes at your initial consultation. There are a few signs that can let you know how old your pipes are. Flakes of rust and corrosion on aged pipes can leave you vulnerable to future pipe bursts and leaks.

Bathroom Installation

Bathroom installation is a multifaceted process, including faucet, shower, bathtub, and drain installation, but they’re all important parts of bathroom renovations and remodels.

Even if your water and electricity have been functioning well in your bathroom, plumbing and electrical components must be updated following current code requirements, possibly even moved to make room for new design features.

When you choose Cornerstone for your bathroom installation, you can trust our expertise to help you make the best decisions for toilet, bathtub, or shower installation.
