Drywall estimating software that wins more jobs

A drywall price is built from five groups of work:

1. Prep and demolition: containment, floor protection, tearing out old board and hauling it away.
2. Insulation: batts, blown-in, sound batts or foam, if they're in your scope.
3. Hanging: walls, ceilings and any special board, like Type X or moisture-resistant.
4. Finishing: corner bead, taping, coats of compound, sanding and texture.
5. Primer and cleanup: a coat of primer on new board, the final sweep and the haul-out.

Measure walls and ceilings separately, then add waste

Measure the two separately, because ceilings hang slower:

• Walls: the room's perimeter times the ceiling height, less openings.
• Ceilings: the floor area.

Then plan extra board for cuts and waste. BuildWell's hanging lines include that extra board, so the materials you price are closer to what you'll have delivered.

Common line items and how each is measured

These are the common lines on a drywall and insulation estimate. Each is measured one of three ways:

• By the square foot: board, insulation, finishing, texture and primer.
• By the linear foot: bead.
• By the each: patches.

The hours and prices are yours to set, and every line's hours are editable.

Finishing takes more hours than hanging

Example: Here's a 12-by-20 room with 8-foot ceilings: about 480 square feet of wall after a door and a window, and a 240-square-foot ceiling, 720 square feet of board in all. The hours below are example figures; say your own records show your crew needs:

Work	Your hours
Hang 480 sq ft on walls	9
Hang 240 sq ft on the ceiling	6
Level 4 finishing, 720 sq ft	16
Final sanding, 720 sq ft	6
Total	37

Hanging is 15 of those hours. Finishing and sanding are 22. That's before corner bead, texture or primer.

It's why a per-square-foot price built around how fast your crew hangs will lose money on every job.

Your labor rate is more than the wage

A drywall installer's wage isn't your labor rate. Your rate has to cover:

• the wage
• payroll taxes, workers' comp and liability insurance
• stilts, scaffolding, lifts, mixers and the truck
• the hours spent bidding, waiting on inspections and coming back between coats

Then it needs a profit.

How BuildWell builds your rate

BuildWell builds your rate in three steps:

1. Wage: the median drywall installer wage for your metro.
2. Overhead: your labor overhead, which starts at 100%, doubling the wage.
3. Markup: your labor markup, which starts at 20%.

Example: Say your drywall installer costs you $25 an hour. Use your real number. The 37 hours on that room come to:

• Wages: 37 × $25 = $925
• With 100% overhead: $1,850
• With 20% markup: $2,220 for that labor

Match the board type to the room

• Standard board for most walls and ceilings.
• Type X where fire separation is required. Residential codes commonly call for it on a garage ceiling with living space above. Check what your jurisdiction requires.
• Moisture-resistant board in bathrooms and other damp areas. Behind tile in a shower, use cement board instead.
• Compound, tape, bead and screws: BuildWell plans them per foot and per square foot, so they scale with the job.

Mark up materials for delivery and breakage

Add a markup that covers delivery, the sheets that crack on the way in and the extra bucket of mud. BuildWell starts material markup at 20%.

If the general contractor is supplying the board, mark it as theirs. It stays on the estimate but isn't charged.

Name the finish level; price Level 5 separately

Finish levels describe how much finishing a surface gets:

• Level 0: board hung, nothing else.
• Level 4: what most painted walls and ceilings get.
• Level 5: a skim coat over the whole surface.

Level 5 is for surfaces under strong side light, glossy paint or a client who wants it perfectly flat. Say in your estimate which level you're pricing, and price Level 5 as its own line.

In BuildWell, the skim coat is its own line, on top of Level 4 finishing.

Price texture matching for the time it takes

Texture is its own line, too. Matching an existing knockdown or orange peel on a patch takes skill, so price repairs with the time it really takes.

Insulation, inspections, patches and lead

• Insulation: many jurisdictions inspect insulation before it's covered, so schedule the drywall after that inspection. Price batts, blown-in and foam by the square foot or foot, and note the R-value in the line.
• Patches and repairs: a patch with wood backing takes about the same trip whether the hole is fist-sized or a foot across, and comes back two or three times for coats. Set a minimum charge, and add it as a line of your own.
• Homes built before 1978: tearing out old drywall or plaster disturbs paint. The EPA's Renovation, Repair and Painting rule requires lead-safe work practices by a certified renovator. When you mark the house as pre-1978, BuildWell puts lead-safe setup and cleanup on the estimate.

Pay depends on market, work and pay method

What drywall installers earn depends on the market, the work and how they're paid. Wages vary between metro areas, and many drywall crews are paid by the piece or the board rather than the hour.

An owner earns the margin between what the job is billed at and what the labor, board and mud cost. Your rate and how you price finishing matter more than any wage table.

Self-employment tax is 15.3%

As a sole proprietor or single-member LLC, you pay self-employment tax on your net earnings: 15.3% in total.

• Social Security, 12.4%: applies to net earnings up to the Social Security wage base, which is $184,500 for 2026.
• Medicare, 2.9%: applies to all of it.
• Deduction: you can deduct half of the self-employment tax on your income tax return.

That's in addition to federal and state income tax, so keep a share of every payment in reserve.

Pay estimated taxes every quarter

No one withholds tax from what clients pay you, so make estimated payments on Form 1040-ES during the year. They're usually due in mid-April, mid-June, mid-September and mid-January.

Waiting until April to pay it all can mean penalties.

Track these deductions as you go

Drywall businesses commonly deduct:

• tools, stilts, mixers, lifts and scaffolding
• the business share of your truck and trailer
• fuel
• insurance and license fees
• dumpster and disposal costs
• phone and software

Keep receipts and log mileage as you go.

Send a 1099-NEC to subs you pay

If you pay an unincorporated subcontractor for services, you'll generally need to send them a Form 1099-NEC. For payments made in 2026 and later, that applies once you've paid them $2,000 or more in a year, up from $600 before 2026.

Collect a Form W-9 before the first payment. Paying a hanger by the board doesn't by itself make them a subcontractor; how you direct the work decides that.

Sales tax on materials depends on your state

States treat drywall contractors differently:

• Some have you pay sales tax when you buy board and supplies.
• Others have you charge it to the client on materials, or on the whole job.

Check your state's revenue department. In BuildWell, sales tax applies to materials only, not labor, at the rate you set.

This is general information, not tax or legal advice. A tax professional who works with contractors can tell you what applies in your state and to your business.
