Introduction

One home. One project. One team.

Home improvement projects rarely involve just one trade. As the work progresses, more people become involved and every new contractor means another decision, another conversation and another opportunity for things to go wrong. We built Renex to simplify that process, giving homeowners one trusted construction company that can manage every stage of improving their home with the same standards, the same communication and the same accountability from beginning to end.

  • In a time when it's hard to trust builders, Caleb stood out by never messing us around.
