Attic Remodeling and Finishing in Mill Creek – Bedrooms, Offices, and More 🛠️🏠

A cozy living room with a vaulted ceiling and skylights, reminiscent of an attic remodeling.

Warm lighting and modern decor create an inviting atmosphere.

A cozy attic room with sloped wooden-paneled walls and ceiling, recessed lighting, and carpeted floor. Two alcove windows allow natural light to stream in. A white door at the far end leads to another space. The attic remodeling showcases clean, minimalistic design.
A cozy interior of a modern loft featuring a small round wooden dining table with black chairs, a white pendant light above, and a wooden staircase leading to an elegantly finished attic area. In the foreground, there's a tan leather sofa against white paneled walls bathed in natural light.
A cozy nook under a slanted ceiling, perfect for an attic remodeling project, features a window with a view of houses. The space includes a star-patterned bean bag chair, a geometric-patterned cushion, and a wicker basket containing books, all placed on a soft carpeted floor.

We 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.

Here’s what we typically handle on a full attic conversion:

  • 🪚 Framing & structural reinforcement – Floor joists upgraded to handle 30 psf live load if current framing isn’t sufficient
  • 🧱 Subfloor installation – Plywood or OSB over reinforced framing, glued and screwed
  • 🌡️ Insulation – R-49 minimum in the roof, R-21 in walls, plus proper baffles for ventilation
  • 🪟 Egress window or skylight – Installed per IRC R310 when converting to a sleeping space
  • 🪜 Staircase construction – New stairs or modification of existing stairs to meet headroom, rise/run, and tread width
  • 🔌 Electrical – New circuits, outlets, lighting, switches, smoke/CO detectors — all brought up to code
  • 🌬️ HVAC – Duct extensions or ductless mini-split depending on system load and attic access
  • 🚿 Plumbing (if needed) – Drain, vent, and supply lines run through walls or ceiling cavities for bathrooms
  • 🧱 Drywall, texture, paint – Full finish work on all walls and ceilings, trimmed and painted
  • 🚪 Doors, trim, flooring – Installed per layout — LVP, carpet, engineered wood, or whatever flooring fits the use

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.

Framing & Structure

  • We frame with #2 or better Douglas Fir from Chinook Lumber, Dunn, or Parr
  • Subfloors go down in ¾" T&G plywood or Advantech — glued, screwed, and tight
  • Fasteners are Simpson Strong-Tie or equivalent — joist hangers, ties, and brackets that hold up

Insulation & Venting

  • For sloped ceilings, we use Owens Corning R-49 batts or blown-in cellulose (when there's access)
  • Ridge vents, baffles, and soffit venting are installed properly — we don’t block airflow or skip baffles
  • All penetrations get sealed with Tremco or Great Stuff Pro foam

Windows & Skylights

  • We install Velux skylights or egress windows from Andersen or Milgard — sized to meet IRC egress rules if a bedroom is planned

Mechanical, Electrical & Plumbing

  • Electrical work is built with UL-rated gear — Square D panels, Leviton switches, Eaton breakers
  • HVAC is either tied into your main system or done with a Mitsubishi ductless mini-split
  • Plumbing (for a bath or laundry) is done with PEX and ABS, sloped and vented per code

Finishes

  • Drywall is ½" standard unless fire-rated is required
  • Flooring depends on use — carpet for bedrooms, LVP for flex spaces
  • Trim comes from Metrie or WindsorONE, always installed with clean corners and returns

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. 🧰📦✅
