About
I have always had a passion for construction, design and increasing home values. From my personal bad experiences with sub par contractors that take on too many jobs or has a sloppy finish, I figured our team can do better than the industry "standard". Being Japanese in this industry, we focus on laser like precision and take pride in our finish carpentry. Fast, Good, Affordable, you get to pick all three.

Hired on Thumbtack

I had a small leak in my bathroom that caused some water damage to the floor trim, and this team handled everything quickly and professionally. They identified the problem right away, repaired the leak, and replaced the damaged trim so it looks brand new. The communication was great, they showed up when they said they would, and the quality of their work was top-notch. It’s such a relief to have the issue fully resolved and the space looking even better than before. I’d absolutely hire them again for any future home projects!

Kohei did indoor and outdoor work on a rental property of ours. Replacing exterior doors; draining the rainwater from the roof to a french drain; interior painting and redoing hardwood floors; plus several smaller projects in the kitchen and bathroom. He was excellent to work with! Great communication, good team, on time and work done well. He won't be your cheapest bid, but you'll get his full attention and a job well done. I highly recommend!

Kohei’s team did a great job. Attention to detail was on point throughout. They removed an old concrete patio and built a new deck with a finished awning. It looks amazing. They also built an extremely well-built fence on the backside of the yard. Kohei was great at communicating throughout any weather delays or other issues. Highly recommended. We will return as customers
