How much does it cost to drywall a 1,500 square foot house?
Short answer
Drywall is priced by the square foot of wall and ceiling surface, not your home's floor plan. A typical 1,500 sq ft home has about 5,000-6,000 sq ft of drywall surface. In the Seattle area, expect costs of $4 to $6 per square foot for installing, taping, finishing, and basic texturing, totaling $20,000 to $36,000.
Surface Area vs. Floor Area: The Key to Drywall Costing
The most common point of confusion is pricing. If your home is 1,500 square feet, you don't need 1,500 square feet of drywall. You need to cover the walls and ceilings. A simple 10x12 foot room (120 sq ft floor) with 8-foot ceilings has (10+12+10+12)x8 = 352 sq ft of wall surface, plus 120 sq ft of ceiling, for a total of 472 sq ft of drywall. A 1,500 sq ft house typically has between 5,000 and 6,000 square feet of wall and ceiling surface, which is the number used for estimating.
What's Included in a Standard Drywall Quote?
A comprehensive quote from My House Spouse for a full drywall installation includes several phases: hanging the drywall sheets onto the framing; taping all seams and corners; applying multiple coats of joint compound ('mudding') to smooth the taped areas; sanding everything for a uniform surface; and applying a final texture (like orange peel or knockdown). We also factor in the installation of corner bead for durable edges. Primer and final painting are typically priced as a separate, subsequent step.
Choosing Your Level of Drywall Finish
Drywall finishes are graded on a scale from Level 0 to Level 5. Level 4 is the industry standard for residential interiors and is what you'll find in most homes; it's ready for a light texture or flat paint. Level 5 is the highest grade, involving an additional skim coat across the entire surface to create a perfectly flawless, smooth wall ideal for glossy paints or areas with critical lighting. Because it's significantly more labor-intensive, Level 5 finish costs more than a standard Level 4.
The My House Spouse Turnkey Process
For a large-scale project like re-drywalling a house, My House Spouse acts as your general contractor. We manage the entire process, including demolition of old surfaces, coordinating with licensed electricians or plumbers if fixtures or pipes need to be moved, installing insulation and vapor barriers, executing the drywall finishing process, and completing the job with professional priming, painting, and trim installation. This provides you with a single point of contact and a seamless, move-in ready result.
Why it happens
The cost for a full-house drywall project is driven primarily by labor, which includes hanging sheets, applying three or more coats of mud, sanding, and texturing. Material costs include the drywall itself, screws, tape, and joint compound. The final price is determined by the total surface area to be covered, the complexity of the layout (e.g., bullnose corners, soffits, high ceilings), and the desired level of finish, with a smooth finish being more labor-intensive and costly than a standard texture.
How to diagnose it
- 1Calculate the total wall and ceiling surface area, not just the floor plan square footage. A quick rule of thumb is to multiply your home's square footage by 3.5.
- 2Decide on the desired finish level. Level 4 (ready for primer and paint) is standard, while Level 5 (a full skim coat) provides a perfectly smooth surface but costs more.
- 3Note any architectural complexities like high ceilings, arches, curved walls, or numerous corners, as these increase labor time.
- 4Determine if demolition of old drywall or lath and plaster is required, as this will add cost.
- 5Specify if you need specialty products like sound-dampening drywall, moisture-resistant board for bathrooms, or extra insulation.
DIY vs. professional
DIY-friendly if…
DIY is feasible for patching small holes or perhaps tackling a single closet, but achieving a seamless finish is a difficult and dusty skill.
Call a pro when…
For a whole-house project or any room where a smooth, professional finish is critical, hire a contractor for the speed, proper tools, and expertise required.

What we see on Home Health Assessments
Nearly 55% of primary bathrooms show grout cracks or a failed tub-surround seal — the #1 quiet water intrusion in Seattle-area homes.
Caught early on assessment: $165–$480 · Left until failure: $1,800–$9,500
A Home Health Assessment can identify underlying issues like hidden leaks or poor insulation that might necessitate drywall replacement. We can then scope the entire project, from fixing the root cause to restoring your walls and paint.
