Drywall Contractor.Square feet to invoice — without the napkin math.

Drywall is the trade where independence is fastest and easiest — and where the difference between thriving and quitting is almost entirely about who you take work from. Most states don't license drywall contractors at the state level. Most counties don't either. You can be operating in 30 days. The trap is that the same low barrier means competition is brutal at the bottom end, where general contractors will ask you for $0.34 per square foot and never pay invoice 60 days late. Below is how to start the business and avoid the trap.

Licensing and structure

Check your state and county. California, Arizona, Nevada, and a few others require a state contractor license at certain dollar thresholds. Most others don't. Pull a city business license and an EIN, form the LLC, get general liability ($1M/$2M), and add commercial auto. Worker's comp once you hire your second helper. Budget: $2,400–$4,800 for first-year insurance.

The truck and the kit

• Used 1-ton work truck or enclosed trailer: $14,000–$26,000
• Hand tools (taping knives, hawk, T-square, utility knives): $300–$600
• Drywall lift: $180 used, $359 new
• Auto-feed screwgun: $200–$400
• Mud pans, sanding pole, mixer: $200–$400
• Dust-extraction sander (Festool Planex or equivalent): $1,200–$1,600 — buys back its cost in two whole-house jobs
• Optional: automatic taper for production work: $800–$2,500 used

Realistic startup: $16,000–$32,000 for a one-truck, one-or-two-person crew.

Crew math: solo, pair, or three-person?

Solo: only viable for repair work and very small jobs (one room max). Pair (hanger + finisher): the most common starting structure; one hangs and stocks while the other tapes and finishes; full-house residential takes 5–8 days. Three-person (hanger + finisher + helper): production setup; same house in 3–5 days. The math favors pair until you have steady weekly volume — a third person on a slow week is just payroll without revenue.

Where to get the first jobs

Three channels. First: direct-to-homeowner via Google Business Profile and Google Local Services Ads — higher margin (typically $0.85–$1.40 per sqft installed), longer sales cycle. Second: small remodel contractors and handymen — relationship-based, cash flow is good, prices middle. Third: production GCs and big-name builders — high volume, terrible payment terms (net-45 to net-90), price compression. Start at 1, mix in 2, avoid 3 until year two.

What to charge in 2026

Hang and finish (Level 4 finish, residential): $1.85–$3.20 per square foot installed depending on metro and ceiling height. Repairs (1-foot patch with paint-ready finish): $145–$385 per patch. Whole-house remodel (level 4, 2,400 sqft of rock): $4,800–$8,200. Don't undercut — the cheapest drywaller in any market is also the busiest and the most burned out.

Our Drywall Toolkit packages the on-truck math — sheet calculator (sq ft to boards, mud, tape, screws), finish-level reference guide, estimate forms, and the punch list / work order template — so you can quote and close from the driveway.

Drywall is one of the few trades where estimating from the parking lot can put you out of business. A 12% under-count of sheets, a 20% under-count of mud, and a customer who thought 'level 4' meant 'level 5' — those three errors together turn a $6,200 job into a $4,800 one. Below is the math that working crews use to quote tight without giving the work away.

Sheet math: the working formula

Take the linear feet of wall, multiply by ceiling height, and divide by 32 (the square footage of a 4x8 sheet). Add 12% for waste on residential, 8% on commercial. Add ceiling square footage separately — divide by 32, add 10% waste. Buy in 12-foot sheets for ceilings and tall walls; the longer the sheet, the fewer butt joints to tape.

Mud: estimate 7–10 gallons of all-purpose joint compound per 1,000 sqft of board for a Level 4 finish; 11–14 gallons for Level 5. Tape: 380 linear feet of paper tape per 1,000 sqft of board. Screws: 1.5 pounds of #6 1-1/4-inch coarse-thread per 1,000 sqft of wall, double on ceiling.

Finish levels: align the customer or eat the difference

Most disputes are not about the work. They're about the finish level the customer thought you were doing. Use this language and show them a photo on each level before they sign:

• Level 1: Tape embedded in joint compound. For service spaces (garage attics, mechanical rooms).
• Level 2: Level 1 plus a single coat over joints and screws. For tile or wood paneling.
• Level 3: Level 2 plus a second coat. Heavy texture only.
• Level 4: Level 3 plus a third coat, sanded smooth, with all screws and corners coated. Light texture or matte paint. This is the residential default.
• Level 5: Level 4 plus a skim coat over the entire surface. Required under glossy or critical-light paint. Adds 30–45% to the cost.

Quoting line items the customer can read

Three line items on a one-page quote: (1) Hang — boards, screws, lift work; (2) Finish — tape, three coats of mud, sanding, level 4; (3) Trash-out and dust control. Each item has a price. The customer can see what they're paying for, and you can defend against the inevitable 'can you take 10% off'.

Our Drywall Toolkit includes the sheet calculator (drop in linear feet and height, get sheet count, mud, tape, screws automatically), the finish-level reference, and the line-item estimate template — everything to quote from the parking lot without leaving margin on the table.

Every drywall job has a punch list. Nail pops, hairline cracks, a corner the painter caught, a soft spot a homeowner noticed two weeks after move-in. On a well-run job, the punch list takes a half-day to close out and the final invoice clears the day it does. On a poorly run job, the punch list eats six Saturday returns over three months and the customer never quite stops finding new items. Below is the discipline that closes jobs clean.

Rule 1: Walk it before you leave

Final walkthrough with the homeowner or GC before the final invoice. Bring a flashlight. Bring a phone. Photograph every item you fix on the spot. Photograph every item that gets added to the punch list. Have the customer initial the punch list before you leave the site. Without an initialed list, you are arguing about scope for months.

Rule 2: One return visit, scheduled at the walk

Schedule the punch-list return at the walk-through — usually 5 to 10 business days after move-in. One return covers all initialed items. Anything found after the return is a separate, billable service call, priced at $145–$285 plus materials. Communicate this in writing. The customer agrees because the alternative — open-ended free returns — is bad for both of you.

Rule 3: The standard one-year warranty

Industry standard for drywall is one year on workmanship — nail pops, hairline cracks at joints, taping flaws. Stress cracks from settling and foundation movement are NOT covered. Print the warranty terms on the final invoice. Most homeowners read it, accept it, and never call again. The ones who do call are calling about real items, which you fix without argument.

Our Drywall Toolkit includes the final-walkthrough punch list template, the standard warranty language, and the one-page customer handout that walks the homeowner through what happens after the final coat — designed to set expectations before they become disputes.
