A message from our CEO
“During the course of running a successful high-end renovation company, we quickly realized we had shifted from the coastal additions and remodels to a heavier focus on custom homes, ADUs, small developments. These various projects were not reflected well in the name and image of Reliable Remodel Co... So, we pivoted! Now rebranded as Probity Construction and Development, although many of our project still maintain remodel/renovation component, we specialize in all forms of construction. We look forward to serving our current and future clients with the same level of integrity and relationship-focus we have for 16 years.” -Derek Runyan
