About OAC Construction

Ethan and Breana Oldham, owners of OAC Construction

Our Story

Who We Are

OAC Construction is a general contractor based out of Ridgefield, WA. We were founded in 2025 by owners Ethan and Breana Oldham. After almost 10 years in the trades, we were tired of watching local contractors build as quickly as possible, with little attention to quality. This poor quality was reflected right from the beginning of the building process and left us with a passion to build something better.

After Ethan had been trying to get into firefighting for quite some time, it became clear that God wasn’t allowing that to happen, but He was opening the door for us to build something of our own. So without a plan, and our daughter only 2 weeks old, Ethan quit his job to follow and honor God and what He had in store for us. While it’s been quite a journey thus far, we are excited to see where God takes it.

Our Mission

What We Do

We offer a host of construction services, and our mission is to do quality work that lasts generations. We’re tired of watching our beautiful properties in Clark, Cowlitz, and Lewis County become subdivisions with postage-stamp-size lots that cost ridiculous amounts of money. We want to create heritage properties with houses that are built to last, room to have a farm or ranch, a place where your kids can be kids, and something to pass to the next generation.

While our mission is ambitious, we are realistic about the fact that we can’t do this all immediately. So for the time being, we offer what we do best.

What Clients Say

“Ethan has been my go to excavating contractor, highly recommended. He does phenomenal work and is always punctual and on time, very attention to detail oriented. Phenomenal work, best excavator in Clark County. He came out to bid my sloped back yard and honestly best prices in town as well — thank you Ethan!”

“Ethan exceeded our expectations. From the beginning, he took the time to listen to our concerns, thoroughly evaluate the site, and clearly explain his recommendations. Our project involved replacing a hand-dug French drain from the 1980s, regrading a steep slope, and installing a long PVC overflow drain to help protect against severe flood events. We especially appreciated his willingness to work within our budget while still providing a high-quality solution.”
