Attic Finishing
Transform your attic into usable living space with our finishing services.
Price starts at $10,000
BrowseWe turn unfinished attics into real, usable space – bedrooms 🛏️, home offices 💻, playrooms 🧸, or full guest suites with plumbing 🚿. Every attic starts with a check – ceiling height, framing, insulation, and how you access the space. If there’s no stairway, we’ll design one that fits without wasting room. Need more headroom? We can add dormers or reframe low sections. Most attics in Mill Creek need new subflooring, proper venting, R-49 insulation, and upgraded electrical ⚡ to pass inspection. We install egress windows or skylights if needed and make sure the whole thing is up to code. From demo to drywall, we handle everything – no bouncing between trades or guessing what’s next. Just one crew, one plan, and a finished space that adds real square footage ✅📏🧰
We finish attics in Mill Creek to meet code and function like any other room in the house. That includes structural, mechanical, insulation, and finish work — everything from rough framing to final trim.
We also handle all permitting, inspections, and any required engineer sign-offs if dormers, structural changes, or load upgrades are involved. If your attic has fire separation requirements (e.g., converting to an ADU), we include that in the scope.

Every attic is different – layout, headroom, structure, and access all affect what’s possible. We don’t guess or wing it. Here’s how we handle it from start to finish:
Step 1: Walk-through & evaluation 🏠
We check ceiling height, roof pitch, structural framing, ventilation, and access. If the space doesn’t meet code, we explain what needs to change — dormers, stair modifications, or structural reinforcement.
Step 2: Scope & pricing 📋
We build a detailed scope of work — framing, insulation, electrical, HVAC, drywall, windows, plumbing if needed. You’ll get a clear estimate with line-by-line pricing.
Step 3: Permits & engineering 🧾
We pull all required permits with the City of Mill Creek and WA L&I. If the attic needs structural changes or ADU fire separation, we include engineering and fire-rated assemblies in the plan.
Step 4: Structural & framing 🪚
We reinforce floor joists, build knee walls or dormers if needed, install subfloor, and prep the space for trades.
Step 5: Trades rough-in ⚡🌬️🚿
Electricians and HVAC come in first, followed by plumbing rough-in (if applicable). Everything is installed to code — no shortcuts.
Step 6: Insulation & drywall 📦
We install R-49+ roof insulation and R-21 in exterior kneewalls. All walls are fully sealed and prepped for drywall. Taped, textured, and ready for finish.
Step 7: Finish work 🧰🎨
We install flooring, trim, doors, paint, and any custom built-ins like shelves or storage nooks.
Step 8: Final walkthrough 📝✅
We walk the job with you, take care of any punch list items, and prep for final inspection.
You’re never left wondering who’s coming or what’s next. We handle every trade and every step — no bouncing between contractors, no delays, and no mess left behind. ✅📅🧼
Attic projects take more than just drywall and trim. You need real structural work, insulation that performs, and systems that pass inspection without problems. We only use code-approved materials — no off-brand stuff or shortcuts.
All materials are from local suppliers — no box-store orders. We plan ahead, order what’s needed, and get everything on site before the job starts. It’s all included in the estimate — no surprises. 🧰📦✅
