Local Knowledge

Remodeling Kent homes

Kent's East Hill and West Hill neighborhoods carry decades of 1970s–90s family homes, the sweet spot for full kitchen and bathroom renovations. We also see steady multi-room projects here from owners updating long-held family houses.

Permits: the City of Kent Permit Center handles residential remodel permits. We handle the entire permit process, applications, plan documents, and inspection scheduling, on every project.

Remodeled my kitchen and got it done a few days faster than expected, and it looks so nice now I can't wait to host people over.

Did an excellent job doing a complete renovation/remodel of our bathroom and repairing/replacing a portion of siding on house. Really listened to what I wanted for my dream bathroom and delivered A+.

Budget & Planning

What to expect on cost

Conversions are one of the best value-per-square-foot projects in a home because the shell already exists. Cost is driven by moisture control, whether you are adding a bathroom, and egress requirements. We assess all three on a walkthrough and price it clearly.

Q & A

Questions, answered straight

Can I add a bedroom in my basement legally?

Yes, with proper egress. A legal basement bedroom needs a compliant egress window or door for safe exit, plus the right ceiling height and ventilation. We handle the egress work and the permit so the room counts as legal living space, not just finished square footage.

Will my basement stay dry after it is finished?

That is the first thing we solve. Before any framing, we address moisture: grading, drainage, vapor barriers, and waterproofing as needed. Finishing over a wet basement is the most common mistake we get called to fix, so we do it right from the start.

Can a garage conversion be an ADU I rent out?

In many cases, yes. A garage conversion can become a legal ADU with the right permits, egress, and utility connections, which we manage. We confirm what your lot and jurisdiction allow before you commit.

Which Kent neighborhoods do you serve?

All of Kent, including East Hill, West Hill, Kent Valley, Panther Lake, plus the surrounding King County area. We're about 30 minutes from our shop.
