What's Included in Insulation & Framing
Insulation & Framing in Seattle & the Puget Sound
Dawn Construction insulates and frames homes in 45 cities across Greater Seattle and the Puget Sound. We add attic, wall, and crawlspace insulation, frame new rooms and basements, remove load-bearing walls with the right beam, and repair rotted framing, with the permits and inspections handled.
Insulation Basics: What R-Value Means
R-value measures how well insulation resists heat flow. The higher the number, the better it insulates. Each part of the house has its own recommended level, and thicker walls can hold more insulation.
When a wall in a heated space is filled in or rebuilt, Washington’s energy code calls for:
| Wall Framing | Insulation Required |
|---|---|
| 2x4 wall | R-15 |
| 2x6 wall | R-21 |
Where Homes Lose Heat
| Area | Common Problem | Typical Fix |
|---|---|---|
| Attic | Thin, uneven, or compressed insulation | Add insulation and seal air leaks into the attic |
| Walls | Older walls with little or no insulation | Insulate when walls are open during a remodel |
| Crawlspace and floors | Cold floors over unheated space | Insulate the floor and protect against moisture |
| Air leaks | Gaps at outlets, pipes, attic hatches, and rim joists | Air sealing |
| Converted spaces | Garages and sheds built without insulation | Insulate walls, ceilings, and floors during the conversion |
Turning a garage or shed into living space? See our garage conversion services.
Insulation Types Compared
| Type | What It Is | Best For |
|---|---|---|
| Batts | Pre-cut rolls of fiberglass or mineral wool | Open walls, floors, and attics with standard spacing |
| Blown-in | Loose fiberglass or cellulose blown into place | Attics and hard-to-reach spaces |
| Spray foam | Foam that expands to fill gaps | Air sealing, rim joists, and tight spaces |
| Rigid foam board | Solid insulation panels | Basement walls and continuous insulation |
Framing for Remodels
Framing is the wood structure behind your walls, floors, and ceilings. Almost every remodel touches it.
| Project | What’s Involved |
|---|---|
| New interior walls and closets | Framing new partition walls for rooms and storage |
| Basement finishing | Framing walls against concrete, plus bedrooms with egress windows |
| Garage and shed conversions | Framing, insulation, and drywall to create living or work space |
| New or wider openings | Headers over new doors and windows |
| Opening up a floor plan | Removing walls and adding beams where needed |
See our interior renovation services.
Removing a Load-Bearing Wall
Some walls only divide rooms. Others carry weight from the floor or roof above. You can’t tell which is which from the room side.
| Wall Type | What It Does | What Removing It Takes |
|---|---|---|
| Partition wall | Divides rooms only | Demolition, patching, and rerouting wiring or vents |
| Load-bearing wall | Carries weight from above | A properly sized beam and posts, a building permit, and sometimes plans stamped by a Washington-licensed engineer or architect |
In Seattle, any work on load-bearing supports needs a permit no matter how small the project.
Rot and Structural Repair
In our wet climate, rot shows up where water gets in and stays. Replacing the wood isn’t enough; the water source has to be fixed too.
- Where the deck meets the house: failed flashing lets water reach the wall framing.
- Around windows and doors: leaks soak the framing under sills.
- Bathrooms: slow leaks under toilets, tubs, and showers rot the subfloor.
- Base of exterior walls: siding too close to soil wicks water into the framing.
- Roof edges: overflowing gutters soak fascia and rafter ends.
- Crawlspaces: damp crawlspaces can rot floor framing.
Permits and Rules
| Rule | When It Applies | What It Means |
|---|---|---|
| Structural permit | Load-bearing walls, beams, new openings, framing repairs | A building permit; sometimes stamped plans |
| Seattle small-project rule | Minor alterations of $6,000 or less in a 6-month period | No permit, except for structural, envelope, egress, light, or ventilation work |
| Energy code | Walls filled in or rebuilt in heated spaces | R-15 in 2x4 walls, R-21 in 2x6 walls |
| Asbestos survey | Before renovation or demolition in the Puget Sound region | Required by Puget Sound Clean Air Agency and L&I rules; some older materials contain asbestos |

Cost – What to Expect
Every project is priced individually. You get a written quote after a free in-home estimate.
| Price Factor | Effect on Cost |
|---|---|
| Area | Square footage of attic, walls, or floors |
| Insulation type | Batts and blown-in usually cost less than spray foam |
| Access | Tight attics and crawlspaces take more time |
| Structural work | Beams, engineering, and permits for load-bearing changes |
| Hidden damage | Rot found once walls or floors are open |

FAQ – Insulation & Framing
What does R-value mean?
R-value measures how well insulation resists heat flow. The higher the number, the better it insulates. Walls, attics, and floors each have their own recommended levels.
How much insulation do new or rebuilt walls need in Washington?
When a wall in a heated space is filled in or rebuilt, Washington’s energy code calls for R-15 insulation in a 2x4 wall and R-21 in a 2x6 wall.
Where does a home lose the most heat?
Common trouble spots are the attic, gaps and air leaks around the house, uninsulated crawlspaces or floors over unheated spaces, and older walls with little or no insulation.
Do I need a permit for framing work?
Usually, yes, when the work is structural, such as removing or moving a load-bearing wall, adding a beam, or replacing damaged framing. In Seattle, any work on load-bearing supports needs a permit no matter how small the project.
Can you remove a wall to open up my floor plan?
Often, yes. If the wall is load-bearing, it needs a properly sized beam and posts, a building permit, and sometimes engineered plans. We check the wall before you plan around removing it.
Can you repair rotted framing?
Yes. Rot is common where water gets in around decks, windows, bathrooms, and the base of exterior walls. We remove the damaged wood, fix the water source, and replace the framing.
Is an asbestos survey needed before insulation or framing work?
In the Puget Sound region, Puget Sound Clean Air Agency and Washington L&I rules require an asbestos survey before renovation or demolition. Some older building materials contain asbestos, so the survey comes before tear-out.
Is it a good time to add insulation during a remodel?
Yes. When walls, ceilings, or floors are open, it’s the easiest and least expensive time to add or upgrade insulation and seal air leaks.
