Interior Remodeling contractor —
Seattle & Puget Sound.
Targeted interior work where you don't need a full whole-home program. Crisp scopes, clean finishes, minimal disruption.
Targeted interior remodeling is the right scope when you don't need a full whole-home program. We tackle a single room or a connected pair — basement finish, primary suite, mudroom-plus-laundry, home office buildout — with clean scopes and minimal disruption to the rest of the house.
Most of these projects do not require a structural permit, which keeps timelines tight and budgets predictable. We still pull permits when we change plumbing, electrical circuits, or framing — that protects resale value.

Codes & permits
COMPLIANCE- Seattle SDCI permits
Required for added plumbing, new circuits, or structural framing changes. Cosmetic refresh in the same footprint is exempt.
- IRC R310 egress
Any room used as a sleeping room must have a code-compliant egress window or door. Basement bedrooms frequently require window-well excavation.
- WSEC 2021 ventilation
New conditioned space in basements may require dedicated supply/return or mini-split for proper HVAC sizing.

Interior questions
FAQQ.01
What rooms can you remodel without a permit?
Cosmetic work in the existing footprint — paint, flooring, cabinetry, fixtures swapped in place. The moment you add a circuit, move plumbing, or change framing, a permit applies.Q.02
How long does a basement finish take?
8–14 weeks for a standard finish; 14–20 if it includes a bathroom, kitchenette, or egress window-well excavation.Q.03
Can a finished basement be a legal bedroom?
Yes, if it has a code-compliant egress window (IRC R310), proper ceiling height, smoke/CO alarms, and HVAC. Without egress, it can be marketed as flex space but not a bedroom.Q.04
Do you handle furniture and decor?
No — we partner with interior designers for FF&E but do not source furniture in-house. Most clients prefer to stage and decorate themselves.
