Don’t let your attic sit unused — RENOVA can turn it into real living space. We handle attic renovation, finishing, insulation, lighting, 🧰 and plumbing rough-ins if you're adding a bathroom or sink. We install skylights and egress windows where needed for code and daylight 🌤️. Most unfinished attics already have the structure in place — finishing it out is usually more straightforward than people think. A finished attic can be a home office, 🎧 guest room, hangout space, or just clean storage with proper lighting and flooring. We build it out clean and up to code.

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

  • Flooring
  • Kitchen Cabinets
  • Doors
  • Decking

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.
