Contractor Jargon Glossary

To an outsider, sometimes it’s hard to know what a contractor is talking about when he gets passionate, excited, or hung up on the details of a project. Using industry jargon is second-nature to a contractor – he’s spent years learning the trade, getting his hands dirty, managing projects, and serving homeowners. If you’re a contractor, it’s easy to get lost in a world of jargon and slang.

Any good contractor in Myrtle Beach should be happy to clarify terms or rephrase a sentence in plain English. No matter how many questions you have, a worthy contractor has an answer you’ll understand.

Sometimes, though, you want to engage a contractor on their level. Whether it’s for the sake of brevity, or for the sake of educating yourself further, you want to understand your contractor’s native language.

Fortunately, we’ve compiled a list of commonly used technical, jargon, and slang terms your contractor might use. When it’s time to start your next home improvement project, you’ll feel more comfortable knowing what your contractor and his crew are saying the first time around.
