What is the cost to hang and finish drywall for an entire 1,600 sq ft house?
Short answer
For a standard 1,600 sq ft home in the Seattle area, the cost to hang, tape, and finish new drywall typically ranges from $15,000 to $30,000. This price varies based on ceiling height, layout complexity, and the desired level of finish, from a basic texture to a premium smooth wall.
Understanding Drywall Costs: Surface Area vs. Floor Space
The single biggest factor in a drywall estimate is the total surface area, not the square footage of the floor. A 1,600 sq ft, single-story home with 8-foot ceilings has a much different drywall quantity than a 1,600 sq ft, two-story home with 9-foot ceilings and a vaulted great room. We calculate the square footage of every wall and ceiling to get an accurate material and labor estimate. More corners, closets, and complex angles also mean more cutting, taping, and finishing time, which increases the cost.
What Do Drywall 'Finish Levels' Mean?
The smoothness of the final wall is defined by a 'level of finish' from 0 to 5. Level 3 is often used in garages where a heavy texture will be applied. Level 4 is the most common standard for homes in the Pacific Northwest, suitable for light textures or flat paints. Level 5 is a premium, skim-coated smooth finish that provides the most uniform and flawless surface, ideal for glossy paints or critical lighting conditions. The jump from Level 4 to Level 5 can increase labor costs by 25-50% due to the extra skill and time involved.
Coordinating a Whole-House Project
Installing drywall across an entire house is rarely an isolated job. It's the 'put-back' phase of a larger renovation. If your walls are open, it's the ideal time to address old wiring, leaky pipes, or inadequate insulation. My House Spouse acts as your general contractor, coordinating trusted, licensed electricians and plumbers for any necessary system upgrades. After their work is complete and inspected, our in-house team takes over to expertly hang, finish, and paint your new walls, restoring your home seamlessly.

What's Included in a Typical Bid?
A standard drywall bid includes labor and materials for hanging gypsum board, applying tape and joint compound to all seams and corners, and sanding to the agreed-upon finish level. Application of a simple texture like 'orange peel' or 'knockdown' is also often included. Items typically quoted separately include demolition of old walls, installing new insulation or vapor barriers, priming, and final painting.
Why it happens
Drywalling an entire house is a major undertaking, usually prompted by one of three scenarios: new construction (like a home addition), a gut renovation where walls are moved, or significant restoration after extensive water or fire damage. It's also common after a whole-house repipe or rewire. Once licensed plumbers or electricians have opened up numerous walls and ceilings to install new systems, a full-scale drywall project is required to put the home back together.
How to diagnose it
- 1Calculate the total surface area of walls and ceilings to be drywalled, not just the home's floor space. A 1,600 sq ft home with 8-foot ceilings can easily have over 4,500 sq ft of drywall surface.
- 2Determine the required 'level of finish'. Level 4 is standard for most residential interiors, while a premium, perfectly smooth Level 5 finish requires more labor and cost.
- 3Factor in the cost of demolition and disposal if you are removing existing drywall, plaster, or lath.
- 4Identify architectural complexities like vaulted ceilings, skylights, archways, and numerous corners, as these increase labor time significantly.
- 5Budget for priming and painting, which are separate steps that follow the completion of drywall finishing.
- 6Consider if other upgrades like new insulation, electrical wiring, or plumbing are needed while the walls are open. This is the most cost-effective time to do them.
DIY vs. professional
DIY-friendly if…
DIY is manageable for patching small holes or replacing a single damaged sheet of drywall where a perfect finish is not critical.
Call a pro when…
For any project involving a full room or an entire house, hiring a professional contractor is essential to achieve a seamless, durable finish efficiently and correctly.
