How Do Drywall Contractors Send Estimates? A Working Method

Short answer: Most drywall contractors send estimates as a PDF within 24 to 48 hours of the walkthrough, same day for a single-room patch and on the bid date for a builder takeoff. The document names the finish level (Level 4 or Level 5) on the first line, lists sheet count by size and thickness, shows corner bead in linear feet, prices ceilings separately from walls, holds the number 15 to 30 days against board cost, and ends with a signature and a deposit line.

Drywall gets bid against two completely different audiences in the same week: a homeowner collecting three numbers for a basement, and a builder’s assistant dropping plan sets into a bid inbox. The document that wins is the one that names the finish level before it names the price, because that single word is what the argument will be about later. The general checklist in what to include on an invoice covers the billing side; below is how the estimate itself gets built and delivered.

How fast does a drywall estimate need to go out?

Speed matters more here than in most trades, because drywall is one link in someone else’s schedule. A homeowner has a painter waiting; a builder has framing signed off and inspection passed. The bid that lands first frames every bid that follows.

Job	Walkthrough to estimate	How it goes out
Ceiling patch or a single water-damaged section	Same visit	Handwritten, photographed, texted before you drive off
One room, hang and finish	Within 24 hours	PDF by email or text
Basement or whole-floor remodel, occupied house	24 to 48 hours	PDF, plus a printed copy left at the walkthrough
Builder takeoff from plans	3 to 5 days, delivered on the bid due date	PDF to the bid inbox, on the GC’s form if they have one
Commercial, multiple finish levels by room	The bid date, not before	PDF with a separate inclusions and exclusions page

The one to protect is the patch. A homeowner with a wet ceiling is not shopping, and a number written on the spot closes that job at a rate no emailed PDF matches two days later.

What has to be on the estimate before the price?

Every block below either survived a walkthrough measurement or is a boundary you will be held to. Missing blocks turn into free work.

Block	What the line says
Finish level	”Hang and finish to Level 4” — line one, not a footnote
Board schedule	Sheet count by size and thickness: 4x12 1/2”, 5/8” Type X at the garage ceiling, moisture-resistant board at the tub surround
Area	Board square footage installed, stated as a number
Ceilings	Broken out from walls, at their own rate
Corner bead	Linear feet, by type: metal, paper-faced, bullnose
Texture	Named: smooth, orange peel, knockdown, or hand texture
Scope boundaries	Who stocks the board in the rooms, who supplies the container, who does the final cleanup
Access	Stairwell walls, ceilings above 9 ft, scaffold or stilts
Exclusions	Priming and painting, insulation, electrical trim-out, framing corrections

Finish level is the largest single variable in the price and the one homeowners cannot see coming. Level 4 is the normal target for flat paint and light texture. Level 5 adds a skim coat over the entire surface, and exists for gloss and semi-gloss paint and for walls raked by critical light — a west-facing great room with a wall of windows, or an entry lit by a single downlight. That skim is a full extra pass over every square foot of board, so pricing a Level 5 wall at a Level 4 number is not a small miss.

Why does the estimate show sheet count instead of the home’s square footage?

Because floor area and board area are unrelated numbers, and the customer will quote you the wrong one. A 2,000 ft² house does not have 2,000 ft² of drywall in it; between walls, both faces of interior partitions, ceilings, closets, and stairwells, the board area commonly runs three to four times the floor area. Use that ratio only as a sanity check on your takeoff — never as the takeoff.

Sheet	Area	Where it earns its keep
4x8	32 ft²	Tight rooms, closets, stairs, anything you carry up
4x12	48 ft²	Long walls and ceilings — fewer butt joints, and butt joints are the slow part of finishing
4x9, 4x10	36, 40 ft²	Rooms with 9 or 10 ft plates, hung vertically without a seam

Count sheets from the takeoff, multiply by the sheet area, then add 10 to 15 percent for waste — more on a cut-up job with soffits and short walls, less on an open new-construction floor. “1,920 ft² of board, 40 sheets of 4x12” is a fact a customer cannot argue with. “Basement drywall” is an opinion, and it will be compared against a cheaper opinion.

How do I build the number the estimate carries?

Work up from your own costs, in this order. Copying a rate you heard at the supply house is how a crew stays busy for a year and ends it with nothing.

Step	The drywall version of it
1. Pick the unit	ft² of board installed, with hang and finish priced separately so you can bid finish-only work
2. Material from the unit	Sheets plus waste, screws, tape, compound by coat count, bead by linear foot, texture mud, corner clips
3. Labor from the unit	Hours to hang, tape, and run each fill coat, times your loaded hourly cost — not your take-home
4. Overhead	Truck, fuel, insurance, stilts and scaffold, phone, storage, the hours you spend estimating
5. Profit	Added as margin, not as markup

Step 5 is where the money quietly disappears. Markup and margin are not the same arithmetic. Take a job whose full cost — material, labor, overhead — comes to $4,200. Add 20 percent markup and you get $5,040, but the profit sitting inside that price is $840 on $5,040, which is a 16.7 percent margin. To actually keep 20 percent, divide the cost by 0.80: $5,250. On one basement it is a $210 difference. Across a year of basements it is a truck.

Two drywall-specific costs belong in step 3 before you commit. Ceilings run higher than walls because the work is overhead: hanging, taping, and coating with your arms up is slower and harder on a crew, so a bid that prices a ceiling like a wall loses money on every square foot of it. And coat count is a real line — a Level 4 finish is a tape coat plus fill coats, and each coat is another trip through the house plus drying time you cannot compress.

Published per-foot ranges are a sanity check and nothing more. They move with region, ceiling height, occupied versus new construction, board price on the day you buy, and how busy the season is. If your build-up lands far outside a range you trust, find the reason in your own numbers rather than editing the price to match.

Paper at the kitchen table, or a PDF?

Both, and the choice is about who is deciding.

Situation	Best format	Why
Repair, one decision-maker present	Written on the spot, signed on the spot	The job closes while you are standing in it
Homeowner remodel, spouse not home	PDF the same evening	It has to survive being forwarded
Builder or GC	PDF on their form, with a scope page	It gets leveled against other bids line by line
Insurance-related repair	PDF, itemized	An adjuster reads it, not the homeowner

Text-message estimates work for repairs and nothing bigger. A bare number in a text has no scope, no exclusions, and no finish level, and it gets treated as a promise covering whatever the customer imagined. If you text, text a PDF.

How many options should a drywall estimate carry?

Three at most, and they should differ by scope rather than by discount. Discount tiers teach a customer that your first number was soft.

Option	What changes
Hang only	You hang and screw off; another crew finishes. Common on builder work
Hang and finish to Level 4	The standard package for flat paint and light texture
Level 5 upgrade	Full skim coat, priced as its own line so the customer sees exactly what the gloss paint costs

Texture is a separate choice from level, and it belongs on the estimate as its own line. Smooth walls hide nothing and take more finishing hours than knockdown does. When a customer asks for smooth after seeing a textured sample, that is a change order and a price, not a preference.

How long should the price hold, and when do I follow up?

Set an explicit expiration: 15 to 30 days is normal, and the shorter end applies when your supplier quoted board and compound with a dated quote. Write it as a calendar date so nobody has to count. If gypsum pricing moves before the customer signs, an expired estimate lets you requote without looking like you changed your mind.

Follow-up is short. Day 2 or 3, a text confirming they got the PDF and asking whether the finish level is what they want. Day 7 to 10, one call about scheduling, because scheduling is the real question — a homeowner who has picked you is thinking about how long the house is unusable. Then one message that closes the loop and releases the slot. Chasing past three touches costs more than the job pays.

How do I record acceptance and the deposit?

Written acceptance, every time: a signature on the estimate, a typed “approved” reply to the email, or a photo of the signed page. All three work. A phone call you remember does not.

Two rules affect what you can collect at that moment. Contracts signed at the customer’s home are generally covered by the FTC’s Cooling-Off Rule, which gives the buyer three business days to cancel a sale of $25 or more made somewhere other than your place of business and requires you to hand over a cancellation notice, with exemptions including a written waiver for emergency repairs. Separately, some states cap what you can take up front: California’s licensing board limits a home improvement down payment to $1,000 or 10 percent of the contract price, whichever is less, excluding finance charges. Check your own state before printing a deposit percentage on anything.

Add one sentence to the acceptance block that saves more arguments than any other: changes to scope, finish level, or texture are priced in writing before the work happens. Then honor it, including the day you would rather just do the extra closet.

What happens to the paperwork once the estimate turns into a job?

The estimate stops being the live document the moment somebody signs it. From there it is a deposit receipt, board and compound receipts from the supply house, mileage between the job and the yard, then a progress or final invoice against the scope you wrote. Keeping those five things under one job name turns a dispute into a two-minute conversation instead of a search through a text thread.

Keel is an iOS app that does that part on the phone, entirely on the device — no account, no bank connection, no cloud, no login, and an App Store privacy label reading Data Not Collected. Once the customer signs, the invoice takes about a minute to build with your own numbering, logo, and brand color, and the payment link renders as a QR code they scan off your screen. The supply house receipt gets photographed at the counter and read on-device by Apple Intelligence. Trips to the yard for another twelve sheets get logged as mileage. Freeboard shows cash minus a tax reserve, minus what you have committed, minus a buffer — the number that tells you whether you can float the board on the next job. Year end exports as one file, or as the Accountant Pack: a CSV plus a one-page summary PDF. The ledger is append-only and hash-chained. Free is $0 with unlimited invoices, receipts, and mileage; Keel Pro is a one-time $249.99 lifetime purchase rather than a subscription. What a deposit receipt has to say, versus the bill itself, is sorted out in invoice vs receipt, and the collection side in how to get clients to pay.

Frequently asked questions

How long should a drywall estimate take to prepare?

A repair or single ceiling can be priced on the spot. A room or a basement takes an hour of takeoff and should go out within 24 to 48 hours. A builder takeoff from plans takes three to five days and goes out on the bid date, not early. The delay that loses jobs is not the takeoff time, it is the estimate sitting unwritten in a truck for a week.

Should the estimate say Level 4 or Level 5?

Say which one, in writing, on the first line. Level 4 suits flat paint and light texture. Level 5 adds a full skim coat over every square foot and is what gloss paint and critical side lighting require. The cost gap is substantial because it is an entire extra pass through the house, so an unstated level is an invitation to be held to the expensive one for the cheap price.

Do I price drywall by the square foot or by the sheet?

Price by square foot of board installed, and count sheets to get there. Sheets tell you material and waste; square feet let you separate hanging from finishing and charge ceilings at their own rate. Never price from the home’s floor area — board area in a finished house typically runs three to four times floor area, so that shortcut underbids badly.

How long should a drywall estimate stay valid?

Fifteen to thirty days, written as a specific date on the document. Board and compound pricing moves, and your supplier’s quote has its own expiration. When a customer resurfaces two months later with your old PDF, an expiration date makes requoting routine instead of a negotiation about whether you are raising the price on them.

How much deposit can I ask for on a drywall job?

Enough to cover material without financing the customer, but check your state first. Several states cap residential down payments outright — California limits a home improvement down payment to $1,000 or 10 percent of the contract price, whichever is less. Where no cap applies, tying the deposit to the actual board and compound order is easier to defend than a flat percentage.

What should I do when the customer wants a change mid-job?

Price it in writing before the work happens, even for something that takes an hour. Adding a soffit, switching a room from knockdown to smooth, or moving a ceiling from Level 4 to Level 5 all cost real hours. A one-line written change order with a number and a signature keeps the final invoice matching the estimate everywhere it should, and clearly separate everywhere it should not.
