Question 1

What is a drywall contract?

Accepted Answer

A drywall contract is a written agreement between a property owner or general contractor and an independent drywall contractor who will install, finish, and/or repair drywall (gypsum board/sheetrock) in a residential or commercial building. The contract covers the full scope of drywall work: hanging (installing sheets of drywall on wall studs and ceiling joists), taping (applying paper or fiberglass mesh tape over joints between sheets), mudding (applying joint compound over tape and fasteners in multiple coats), sanding (smoothing dried joint compound to create seamless surfaces), and finishing (achieving a specified level of smoothness from Level 0 through Level 5 per ASTM C840 standards). The contract defines the project scope, materials, finish level, payment schedule, timeline, warranty, cleanup responsibilities, and compliance with building codes and licensing requirements.

Question 2

What are the different drywall finish levels?

Accepted Answer

The Gypsum Association defines six levels of drywall finish (Levels 0-5), each representing increasing degrees of smoothness and preparation. Level 0: No taping, mudding, or finishing — used in temporary construction or areas where finishes are not yet specified. Level 1: Tape is embedded in joint compound at flat joints and interior angles; no additional coats — used in attics, above ceilings, and in garage spaces not visible to the public. Level 2: One additional coat of joint compound over tape and over fastener heads — used in areas receiving tile, in garages, and in warehouse areas. Level 3: Two additional coats of joint compound (three total including embedding coat) — used under medium-to-heavy-weight wall textures. Level 4: Three additional coats at flat joints, two at interior angles, three over fastener heads — the standard for most residential and commercial painting with flat or semi-gloss paint. Level 5: A skim coat of joint compound over the entire surface — required for high-gloss, semi-gloss, or enamel paints, and for areas with critical lighting (raking light) that would reveal even minor surface imperfections. The finish level dramatically affects both the cost and the labor time required.

Question 3

Does a drywall contractor need a license?

Accepted Answer

Licensing requirements vary by state and sometimes by municipality. Some states (California, Arizona, Nevada, Oregon) require a specific contractor's license with a drywall specialty classification (California's C-9 Drywall license, for example). Other states require a general contractor's license for projects above a dollar threshold but do not have a drywall-specific classification. Some states (Texas, for certain project sizes) have no state-level licensing requirement but delegate licensing to cities and counties. In addition to the contractor's license, many jurisdictions require a business license, liability insurance, and workers' compensation insurance. The contract should require the drywall contractor to hold all licenses and permits required by the state and local jurisdiction where the work will be performed, and to provide copies upon request.

Question 4

How should payment be structured in a drywall contract?

Accepted Answer

Payment structure depends on the project size. For small residential projects (single room, patch repairs): a 50% deposit at signing and 50% upon completion is standard. For larger residential projects (whole-house new construction or remodel): a progress payment schedule tied to milestones is typical — 25% at signing, 25% when hanging is complete, 25% when taping and mudding are complete, and 25% upon final inspection and punch list completion. For commercial projects: net-30 payment terms with monthly progress invoicing based on percentage of completion are standard. The contract should specify that the final payment is not due until the work passes inspection and any punch list items are resolved. Avoid front-loading the payment schedule (paying more than 50% before substantial completion), as this reduces the contractor's incentive to complete the work and leaves the property owner at risk if the contractor abandons the project.

Question 5

What materials should the contract specify?

Accepted Answer

The contract should specify the type, brand (if applicable), thickness, and fire rating of all drywall materials. Standard materials include: drywall sheets (1/2-inch for most walls, 5/8-inch for ceilings to prevent sagging, 5/8-inch Type X fire-rated for garage walls, furnace rooms, and any area requiring fire-rated assemblies); moisture-resistant (green board) or mold-resistant (purple board) drywall for bathrooms, kitchens, laundry rooms, and other high-humidity areas; cement board or Kerdi board for tile backer in wet areas (showers, tub surrounds); joint compound (all-purpose, lightweight, or setting-type — the choice affects drying time and strength); joint tape (paper or fiberglass mesh); drywall screws (coarse thread for wood framing, fine thread for metal studs); and corner bead (metal, vinyl, or paper-faced for outside corners and archways). The contract should specify who provides materials — the contractor or the property owner — and how material cost overruns are handled.

Question 6

What warranty should a drywall contract include?

Accepted Answer

A drywall warranty typically covers defects in workmanship — nail pops, tape bubbles, visible joints, cracking at seams, and uneven surfaces — for one to two years after completion. The warranty should specify what constitutes a defect (a nail pop or joint crack within the warranty period is a workmanship defect; a crack caused by structural settling is not), the contractor's obligation to repair defects at no additional charge, a reasonable response time for warranty claims (typically 14-30 days), and exclusions for damage caused by the property owner (hanging heavy items without anchors, water damage from plumbing leaks, damage during subsequent construction work by other trades). Some states have statutory warranty provisions that apply to construction work regardless of what the contract says — California's SB 800, for example, establishes performance standards for residential construction defects that override contractual warranty limitations.

Question 7

How does drywall work interact with other trades?

Accepted Answer

Drywall installation occurs at a specific point in the construction sequence and must be coordinated with other trades. Before drywall: framing must be complete and inspected; electrical wiring, plumbing pipes, and HVAC ductwork must be installed and inspected (the rough-in inspection must pass before drywall covers the walls); insulation must be installed; and any structural headers, blocking for future fixtures (TV mounts, grab bars, heavy shelving), and fire-stop treatments must be in place. After drywall: painting cannot begin until the specified finish level is achieved, joint compound is fully dry, and sanding dust is cleaned; trim carpentry (baseboards, crown molding, door casings) installs after painting; and flooring typically installs after drywall and painting are complete. The contract should address scheduling coordination with other trades, the contractor's responsibility to protect completed work from damage by subsequent trades, and the general contractor's obligation to ensure that prerequisite work (framing, rough-ins, insulation) is complete and approved before the drywall contractor begins.

Question 8

What about dust control and cleanup?

Accepted Answer

Drywall sanding generates significant fine dust that can spread throughout a building and damage HVAC systems, finishes, and electronics. The contract should address: dust barriers (plastic sheeting, zip walls, or temporary partitions to contain dust in the work area); dust collection equipment (the contractor should use a vacuum sander or dust collection attachment on power sanders to minimize airborne dust); HVAC protection (return air vents and supply registers should be covered during sanding to prevent dust from entering the duct system); daily cleanup of the work area (sweeping, vacuuming, and removing debris at the end of each work day); final cleanup upon project completion (thorough vacuuming, wiping of all surfaces, removal of all scrap drywall, empty joint compound containers, and other construction debris); and disposal of waste materials (drywall is not accepted in all landfills, and some jurisdictions require recycling — the contract should specify who is responsible for proper disposal).

Question 9

What insurance should a drywall contractor carry?

Accepted Answer

A properly insured drywall contractor should carry: general liability insurance ($1 million per occurrence / $2 million aggregate minimum) covering property damage, bodily injury to third parties, and completed operations claims; workers' compensation insurance (required in most states for contractors with employees, and advisable even for sole proprietors because property owners can be held liable for a contractor's workplace injuries if the contractor is uninsured); commercial auto insurance if the contractor uses vehicles to transport materials and equipment; and an umbrella policy for additional liability coverage on large commercial projects. The contract should require the contractor to provide certificates of insurance before beginning work, maintain coverage throughout the project, and notify the property owner immediately if any coverage lapses. Some property owners also require the contractor to carry a contractor's pollution liability policy covering claims related to drywall dust, silica exposure, or asbestos disturbance (relevant in renovation projects involving older buildings).
