Our approach

Built to match the house you already have

Rooflines, windows, siding and interior trim all decide whether an addition looks like it belongs. We plan how the new space ties into your existing structure, systems and finishes before construction begins, then manage the build from start to finish with one hands-on point of contact.

We had the pleasure of working with Tanner, and couldn’t be more impressed! From start to finish, he was incredibly kind, helpful, and professional. He took out a wall in our office, which completely opened up the space. He then re-did the flooring, transforming the entire look and feel of the area. The modernized design has truly elevated the office, and we couldn’t be happier with the results! The quality of his work is exceptional, and it’s clear he takes great pride in what he does. We highly recommend Tanner for any project – he’s got the skills and dedication to get the job done right!

Communication is key in construction and Tanner is fantastic at that! First project with Keep Hammering Construction LLC and the project went very well. Tanner is knowledgeable, respectful of the people that trusted him to do the work, and able to direct the project toward a great end. I would trust Tanner at KHC for any construction needs!
