Our Basement Finishing Services
Fast, reliable solutions for Carnation landlords and property owners
Permit & Code Navigation
Every basement project in Carnation requires proper permits and must meet King County building codes. Our contractors handle all permit applications, inspections, and keep your finished space meets egress requirements, ceiling heights, and moisture mitigation standards, protecting your investment from future compliance issues.
Design for Maximum ROI
Not all basement layouts deliver equal returns. We help you design spaces that maximize rental value, whether that's an ADU with separate entrance, an additional bedroom to bump rent $400-600 monthly, or a media room that attracts premium tenants in the Carnation market.
Moisture & Foundation Assessment
Carnation's proximity to the Snoqualmie Valley means basement moisture requires serious attention. Before finishing work begins, our contractors assess foundation integrity, drainage systems, and moisture levels, then start proper vapor barriers, sump pumps, or French drains to prevent the mold and water damage that destroys unfinished basements.
Electrical & Plumbing Rough-In
Adding basement living space means upgrading electrical panels, running new circuits, and potentially adding bathroom plumbing. Our electricians and plumbers coordinate rough-in work before drywall goes up, so everything passes inspection the first time and avoiding the change orders that blow up budgets.

From drywall and flooring to trim and paint, we manage every detail through final inspection. You get a turnkey space ready for tenants, not a half-finished project that sits for months while you hunt for available contractors to complete punch list items.
