How to Bid a Remodeling Job (Step-by-Step, Real Numbers)

A remodeling bid isn't one estimate. It's six sub quotes, a materials list, your overhead, your margin, and a schedule that has to survive five trades walking through the same kitchen. Miss any one of them and the job pays for it, not you.

Here's the promise: this guide walks one real bid end to end - a minor kitchen remodel, from demo to a submitted number of $32,568. You'll see every line that got there, the two tables most competitors skip, and the change order habit that keeps the margin you bid.

No theory. Every number below comes from trade pricing data or sources we'll name as we go.

The Whole Bid on One Page

Before the step-by-step, here's the finished math. This is a 1990s ranch, minor kitchen remodel: keep the layout, replace cabinets, counters, flooring, and paint. The numbers follow the exact workflow we'll unpack below.

Two things to notice. First, your subs are 80% of the direct cost - remodeling GC-ing is a purchasing and coordination job, not a carpentry job. Second, the overhead and margin lines are where remodelers lose money, because they bid them as feelings instead of percentages.

Now let's see whether $32,568 can actually win work. That's where the next table comes in.

What the Market Says a Remodel Should Cost

You don't price in a vacuum. The Remodeling Magazine / Zonda Cost vs Value Report (2025 edition, published January 2025) tracks what common remodels cost and what they return at resale, across roughly 100 US markets.

Use it like this: if your worked bid lands at $32,568 against a $28,458 national average for the same scope, you're not "too expensive" - you're 14% over a national number that blends cheap rural markets with expensive coastal ones. That's a conversation you can defend line by line. A bid you can't defend is a bid you discount in panic at the kitchen table.

And that's exactly what the next seven steps protect you from.

Step 1: Walk the Job and Ask the Questions That Change the Number

Remodeling bids go wrong at the walkthrough, not at the spreadsheet. You're bidding work inside someone's home, often while they live in it. That changes what you need to know.

Ask before you price:

• Are you living in the house during the remodel? Occupied kitchens mean dust barriers, daily setup and teardown, and a schedule built around the family's hours.
• Has anyone opened the walls before? A 1990s ranch can hide knob-and-tube wiring, galvanized supply lines, or a previous owner's creative plumbing. Any of them turns a $1,400 electrical sub quote into a rewire conversation.
• Who picks the fixtures and tile? If you're buying, you need an allowance with a number in it - "$3,400 for fixtures and tile, homeowner picks from these three brands" - not "TBD."
• What's the permit situation in this jurisdiction? Permits add fees and add weeks. Both belong in your bid, not in a surprise after the deposit.

Skip these questions and you're not bidding the job. You're bidding the job you imagined while driving over.

Step 2: Get Sub Quotes - and Notice They Never Arrive Together

Here's the remodeling bid problem no software landing page mentions: your six subs don't quote on your schedule.

The cabinet shop needs two weeks. The plumber walked the job Tuesday and texted a number Friday. The electrician's quote lands three days after you've already submitted - and it's $600 higher than the allowance you carried. Every GC knows this dance. The trap is quiet: when quotes trickle in, GCs fill the gaps with allowances, and allowances are where bids die.

Three habits that keep this from eating you:

1. Carry an explicit allowance line for anything unquoted - like the $3,400 fixtures line in our sample bid - so an unpriced item never masquerades as a covered one.
2. Date-stamp every sub quote and re-confirm before you submit. Material prices move; a plumbing quote from three weeks ago on copper is a different number today.
3. Bid your subs' exclusions, not their inclusions. The flooring quote that says "furniture moving excluded" is your cost, not the sub's.

Step 3: Price Your Own Labor - the Part Subs Don't Cover

Your subs' quotes cover their crews. They don't cover yours: demo supervision, material runs, coordinating five trades in one kitchen, and the daily cleanup that keeps a homeowner sane.

Two ways to price it:

• Role-based: your PM or lead carpenter's loaded hourly rate × estimated hours. If your loaded rate is $52/h (more on how burden works in our guide to calculating construction labor cost) and coordination eats 60 hours across the project, that's $3,120 of real cost.
• Allowance-based: many remodelers carry a project management line of 8-12% of direct cost instead. On our sample bid, that's $1,900-$2,800.

Either way, the labor line is honest only if it counts the hours you actually spend - including the Saturday you spent at the supply house because the tile order shorted two boxes.

Step 4: Load Your Overhead Before You Name a Margin

Overhead is what it costs to exist as a business: insurance, truck, office, accounting, licenses. For small contractors it typically runs 20-40% of revenue depending on how much work you self-perform. GCs who subs everything out run leaner; GCs with crews and a shop run heavier.

One overhead line keeps climbing faster than the rest. Commercial liability insurance has risen for 20+ consecutive quarters, with general liability renewals averaging roughly +4-5% a year (CIAB quarterly survey, 2025 Q2 +4.66%) and umbrella layers rising even faster. If your overhead rate is two years old, it's understated - and every bid built on it inherits the hole.

In our sample bid, overhead is 15% of direct cost ($3,540). If yours is 25%, your floor is higher than the next guy's - which is fine, as long as you know it and bid it.

Step 5: Set Your Margin on Purpose, Not by the Competition

Markup and margin get mixed up constantly, and the confusion quietly changes what lands in your pocket. Markup is what you add to cost; margin is what profit is as a share of the sale price. A 20% markup on $27,140 of cost-plus-overhead isn't a 20% margin - it's 16.7%.

If that distinction is fuzzy, our breakdown of contractor markup vs margin walks the math with dollar figures - it's the difference between hitting your income plan and hitting it minus a month's profit.

What margin should a remodeling GC target? There's no universal number, but the logic is: enough to absorb the change orders you'll mis-handle, the warranty call in month nine, and the job that runs long through no fault of yours. GCs who bid at 10% because a competitor did aren't cheaper - they're subsidizing your job with their cash flow until it runs out.

In our sample: 20% markup = $5,428. That's the line that pays for the months when two bids you lost turn into a slow pipeline.

Step 6: Build the Schedule Buffer - Because Five Trades Share One Kitchen

Single-trade contractors bid a sequence they control. You bid a choreography you don't: the cabinet install slips a day, so the counter templater slips, so the plumber returns on a different day than scheduled, so the painter starts late.

Experienced GCs carry a project-time buffer of roughly 10-15% on remodeling work. It's not padding to hide in - it's a line item with a name ("schedule contingency") and it shows up two ways:

• Extended general conditions: more days of site setup, cleanup, and supervision = more of your Step 3 labor.
• Occupied-home friction: working around the family adds hours no takeoff captures.

If your bid prices a perfect schedule, you've bid a job that doesn't exist. Price the real one - the one where the countertop template shows up three days late and the family takes a long weekend in the middle of it.

Step 7: Submit Fast, Then Protect the Number in Writing

Two habits at the finish line, and both are about time.

Speed wins the job more often than price does. The Harvard Business Review's study of online sales leads (Oldroyd et al., 2011) found that responding within an hour makes a lead about 7x more likely to qualify than waiting two hours - and over 60x versus waiting a day. The same psychology runs through remodeling bids: homeowners collecting three bids remember who got theirs in first, understood, and complete. Being the fast, organized bid is a positioning advantage no discount buys.

Then hold the number with written change orders. Remodeling is the trade where scope moves mid-job - the owner sees the open wall and wants the outlet moved, the cabinet hardware upgrades itself. Verbal agreements on changes are how a profitable job turns into a favor you did for someone. Price the change, get a signature, then touch the work. Our guide on pricing construction change orders covers the paperwork side in detail.

A bid that wins because it was fast and a job that stays profitable because changes were written down - those two together are the whole game.

Template or Software: What to Bid With

Pick by volume, not by ambition:

• Under ~3 remodel bids a month: a solid template is enough. Our free general contractor estimate template gives you the line-item structure - subs, allowances, overhead, margin - so nothing gets forgotten at 11pm the night before it's due.
• Bidding weekly, with subs to chase and changes to track: you've outgrown templates. The coordination cost - quote tracking, revision trails, change orders - is what software is for. Our takeoff vs estimate comparison shows which tools handle which parts of that workflow.

The expensive mistake is the reverse: buying a platform for a bid volume that a template handles, or hand-building six spreadsheets a month that software would finish in one.

The Bottom Line

A remodeling bid is a purchasing document wearing a construction hat. Your subs are 80% of the cost, your schedule is shared with four other trades, and your profit lives in the overhead and margin lines you refuse to guess at.

Walk the job and ask the questions that change the number. Date-stamp your sub quotes. Load your overhead at this year's insurance rates. Set margin on purpose. Buffer the schedule. Submit fast, and write down every change.

Do that, and $32,568 isn't a hope - it's a number you can defend while the homeowner signs it.

FAQ

How much should I mark up a remodeling job?

There's no universal number, but small remodeling GCs commonly need 20-30% markup on direct cost to cover overhead and real profit after warranty work and slow months. What matters more: know your own overhead rate first, then set markup on top of it - not the other way around.

What's the difference between a remodeling bid and an estimate?

An estimate is your internal calculation of what the work will cost you. A bid is the offer you hand the homeowner: that cost, plus overhead and margin, with a scope and schedule attached. Homeowners see the bid; you'd better know the estimate behind it line by line.

How do I handle sub quotes that arrive after I've already bid?

Carry an explicit allowance for anything unquoted at submission, and re-confirm quotes before you submit - material prices move. If a quote lands late and higher, the change order process - not your margin - absorbs the difference.

Homeowners keep telling me my bids are too high. What do I do?

Defend the number with structure, not discount. Show the line items, reference third-party pricing like the Cost vs Value Report for the scope, and be honest that the cheap bid down the street is bidding a different job - one without schedule buffers or written change orders. The homeowner who only buys price will find that out later.

Do I need a separate bid for every phase of a remodel?

No - one bid, one contract, phased billing. Break the schedule into phases (demo, rough-in, finish) for draw schedules and progress payments, but keep the scope and price in a single document. Two contracts for one kitchen is how scope gaps get born.

How long should a remodeling bid stay valid?

30 days is the common window, and it's not arbitrary: material quotes - especially lumber and copper - move inside a month. If the homeowner signs in week five, you're re-confirming your subs' numbers before mobilizing, not honoring a bid built on stale pricing.
