  • When you work with Concept Construction you partner with a staff of skilled craftsmen and subcontractors committed to excellence.

  • We believe in a hands-on approach. We’ve built our business on the referrals of happy customers and continue to give each project an unprecedented level of individual attention.

  • By limiting the number of projects we accept and our service area we can be very responsive, which facilitates greater efficiency on the project and a more pleasant experience for the homeowner and design team.

  • Because we are agile we can respond quickly to changes throughout the construction process.

  • The employees and subcontractors at Concept Construction ensure the highest levels of finish for every home.

  • We only know how to complete projects to the highest level of craftsmanship and believe that, with each finished project, we build a relationship that lasts a lifetime.

  • Many clients return to us time and again for routine maintenance and new projects. As trusted partners, we are happy to provide this ongoing service.
