Commercial Plumbing System Installations in Columbia & The Surrounding Areas
Whether you’ve got a new construction or you’ve been operating for years, you need a plumbing company that can meet your needs, expectations, and schedule. Kay Plumbing comes at the time we’ve scheduled with you, and our pricing quotes will match what you see on the receipt.

Experts on Your Construction Project Who Know Your Legal Plumbing Needs
Different commercial properties must follow not only different state plumbing codes, but municipal-specific codes, too. These codes dictate the specific fixtures you must install in your business and how they should be installed.
Kay Plumbing has been serving South Carolina since 2008. We know our state and local municipal codes. We can explain to our customers what we’re doing and why, and we can answer any questions you have about our work – without jargon.

Gas Line Installation
A professional installation service is crucial for the job to be done right and efficiently.

Frequently Asked Questions
What should I ask a commercial plumber before hiring them?
Whether you’re looking for small plumbing repairs or you need a sizable project completed, you’ll want to make sure you’re getting the plumbing services you need at the quality you’re expecting. Before asking a plumber to come out or signing a contract with one, think about asking some of the following:
- Do they charge a fee to visit your property and give an estimate for what you want?
- Do they offer any warranties on their work? If so, what kind?
- How will they charge you – by the hour, or at a flat rate?
Particularly in the case of a large or complicated project, how will they ensure plumbing staff and your people and property are kept safe? - How much experience do they have in commercial plumbing services and/or with the specific project you need done?
These questions and more will allow you to set expectations and decide whether you’ll work well with the company.
Do I need a commercial plumbing contractor? What’s the difference from residential plumbing?
If you run a brick-and-mortar business, then yes. A commercial plumber knows what your business needs and how to manage the more complicated plumbing that comes with it much better than a residential plumber.
The key difference between a commercial and residential plumber is expertise. Even for a small business that doesn’t have the specialized needs of something like a restaurant, the plumbing is going to be more complex than a home’s plumbing because, more than likely, there’s going to be a lot more of it under heavier use. Additionally, different laws regulate residential and commercial plumbing systems, and you won’t be able to operate if you don’t meet commercial code.
