Like many industries, builders use a variety of jargon − words and phrases that act as shorthand when people who work within it talk to each other.
At John O’Connell Building Solutions we know that people outside the industry in most cases won’t understand these terms, so we try not to use them when talking to customers. Despite this, we’re aware that we may occasionally include some of this jargon when we’re talking about what we do.
So, along with our Glossary we’ve come up with our own ‘Jargon Buster’ to help you learn more about some of the language commonly used within the construction industry.
