How we work
At RENOVA, we approach attic remodels like real construction projects — not just drywall and paint. Most attics in Seattle weren’t built to be lived in, so we start by checking structure, headroom, and access. If you're planning a bedroom, office, or bonus space, we’ll make it meet code and actually work as part of the house.
Attic Finishing Seattle 🛠️🏠
- First thing we check is usable ceiling height. Seattle code needs 7' over at least 50% of the floor. If it doesn't meet that, we look at dormers or vaulted framing.
- If you’ve got a pull-down ladder or sketchy stairs, we replace it with a permanent, code-compliant staircase (36″ wide, 6′8″ headroom).
- Most attics need new floor framing to meet live load (30–40 PSF). We reinforce joists or frame new ones as needed.
- We insulate with spray foam or batt, depending on roof structure — R-49 required in unvented cavities.
- If you’re adding a bedroom, we install egress windows or add dormers to meet emergency exit requirements.
- 🔥 Smoke alarms and fire-rated drywall are installed throughout, tied into the rest of the home.
- Electrical is fully rewired for the space — outlets, lights, and sometimes a dedicated panel if load requires it.
- HVAC is either ducted off the main system or we install a ductless mini-split for heating + cooling.
- We finish with drywall, doors, trim, lighting, flooring, and paint — usually LVP or carpet for comfort.
- 📝 We pull permits. If it’s non-structural, we can often use the STFI permit process to speed things up.
Once we’re done, it feels like part of the house — not like an attic with drywall. Everything’s up to code and ready to use, whether you’re turning it into a guest room, a home office, or just adding livable square footage without touching the foundation.
Products For Succesful Attic Finishing
Finishing an attic in Seattle isn’t just about looks — you need the right materials or it'll fall apart in a few seasons. Most old attic floors aren’t strong enough, so we usually reinforce joists and lay 3/4” tongue-and-groove plywood over them, glued and screwed. You don’t want bounce up there.
🪚 Structural Stuff
- We check the floor for live load first (usually 30–40 psf — IRC R301), and fix it if needed.
- New walls? We frame with 2x4 studs @ 16" O.C., just like anywhere else. Short knee walls get blocked tight so drywall doesn’t flex.
🧯 Fire & Safety
- If it's a bedroom or anyone’s sleeping up there, we put in egress windows or build a dormer — gotta hit 5.7 sq ft clear opening (IRC R310).
- All ceilings and shared walls get Type X 5/8" drywall (IRC R302).
- And yes — smoke + CO detectors, hardwired and linked to the rest of the house (IRC R314 & R315).
🧰 Interior Materials
- For walls: we usually use standard drywall, finished to level 4 or 5.
- Floors: LVP, carpet, or sometimes engineered wood if it's climate-stable.
- Ceiling lights? Mostly recessed LED or flush-mounts if headroom’s tight.
- HVAC usually means a ductless mini-split unless we can tap into existing ducts cleanly.
