Drywall is a common building material for walls and ceilings. It is created by compressing gypsum plaster and is covered by thick paper.
Sheets of drywall have varied prices based on the type of drywall and thickness. The typical thickness of drywall is 1/2 inch or 5/8 of an inch.
The standard size sheet is 4′ by 8′. Normally priced by the square foot, the average cost of drywall is approximately 30 – 33 cents per square foot. The average cost of a 4′ x 8′ sheet is $7 – $10 for the 1/2 inch thickness and $8.00 – $12.00 for 5/8 inch thickness.
Contractors often voice preferences in brands of drywall. Given the highest marks are the brands USG and National Gypsum. The lowest scores are given to the brands Georgia-Pacific and Lafarge. These scores are based on durability of the drywall when cut and how well it secures to wall studs.
Abuse-resistant drywall has a polystyrene layer providing heat insulation, and the fiber mesh of the core stands up to high-traffic areas.
Moisture-resistant drywall is used in bathrooms and kitchens where its special surface coating makes it ideal for laundry and utility rooms.
Sound-proof drywall is a nice fit for children’s rooms. The soundproof drywall contains additional layers to absorb sound.
Foil-backed drywall is for cold, low humidity climates. The foil is laminated on to the panel and is an effective vapor retardant.
Fire-resistant gypsum drywall contains glass fiber and additives within the core to stand up to fire exposure. This type is best suited for basements or any other room containing a fire burning stove or fireplace.
Drywall is cut to the desired size using a t-square and a utility knife. It is scored and broken off along the cut. The electrical outlets and light switch holes are cut with a keyhole saw. The drywall is attached by nails, glue or drywall screws. The panels are then covered at seams with drywall joint tape and compound. This compound is also called mud. It is applied to cover screws and imperfections. The entire drywall can be covered in mud called a skim coat. Once dry it is sanded down flat and ready for paint.
The cost of labor to hang drywall from a licensed and bonded contractor is an average of $1.82 – $1.96 per square foot. Get at least three estimates before choosing a contractor for your job. An estimate of calculating square footage is found by multiplying the length and width of each wall and ceiling. If a wall is 15′ by 8′ then multiplying the two would give you 120 square feet. You would need to add the square feet of each wall and ceiling together to get an accurate measurement of square feet for the room. The cost to drywall varies considerably between states and contractors. Research and obtain written estimates from varied businesses to insure your next drywall project is finished with confidence and professional results.
