Introduction

We're Renex, Lancashire's customer-first construction company.

Most homeowners spend weeks (or even months) comparing companies, reading reviews and trying to work out who'll match their promises when they're on site. All they want is a team who builds with care, turns up on time, gets stuck into the job, respects their home and is available to talk if questions arise.

We built Renex around that mindset. We believe great work, honest advice, clear communication and transparent pricing should be the standard not the exception and we're committed to proving it.

  • Caleb truly went above and beyond, always arriving on time and finishing the job exactly when he said he would.

Caleb is an absolute star. We've been lucky to have him do two quite sizeable projects for us, and both are amazing. He turns up when he says he will, gets stuck into the job, and doesn't stop until it's done. Great communication, great design ideas, and a great work ethic all add up to a fantastic experience and end result.
