How to Get and Compare Contractor Quotes the Right Way

A line-by-line method for gathering apples-to-apples contractor bids, spotting padded numbers, and reading quotes like an estimator instead of guessing.

Last spring a homeowner in Ohio sent me three bids for the same bathroom job: $9,400, $14,800, and $21,200. Same room, same square footage, same week. Her question was the one I hear most: which one is honest?

The answer is that none of them was lying. The cheap bid skipped the subfloor repair and used a builder-grade vanity. The expensive one carried a fat contingency and a premium tile allowance she did not ask for. Once I lined the three up side by side and matched line item to line item, the real gap shrank to about $2,000.

That is the whole game. A quote is not a price tag, it is a story about what the contractor plans to do and what they plan to skip. Here is how I get bids that compare cleanly, then read them the way an estimator does.

Write the scope before you call anyone

If you hand three contractors a vague idea, you get three different jobs priced three different ways. The single biggest reason quotes look thousands apart is that each one is bidding a slightly different project.

So write it down first. List the rooms, the rough dimensions, the materials you want, and the things you specifically do not want touched. Note who supplies what. Two pages of plain text is plenty.

Pin down your material grade in writing. "Tile" can mean $3 a square foot or $18 a square foot. When you fix the grade, the bids vary on labor and overhead, which is exactly where the real differences live.

Collect at least three bids on the same scope

Three is the floor, not the goal. With one bid you have no reference point. With two you cannot tell which one is the outlier. Three gives you a middle and two edges, and the edges are where I start reading.

Give every contractor the same written scope and the same deadline. If one walks the job and asks sharp questions about your subfloor or your panel, that is a good sign. The estimator who quotes from the driveway is guessing, and you will pay for the guess later.

Make the bids speak the same language

Bids arrive in wildly different formats. One is a single number on letterhead, another is a four-page breakdown, a third is a text message. Before you can compare anything, you have to normalize them onto one sheet.

I use a simple column layout: labor, materials, demolition and disposal, permits, allowances, and contingency. Then I drop each contractor's numbers into those rows. The point is not precision, it is exposure. When you force every bid into the same buckets, the missing rows jump out.

This is also where understanding how contractors price jobs pays off, because once you see that a "cheap" labor line is cheap because it excludes the tear-out, the savings evaporate on the page.

Compare line by line, not bottom to bottom

The total is the last thing I look at. I read up from the line items, because that is where padding and gaps hide.

Watch the allowances first. An allowance is a placeholder dollar amount for something you have not picked yet, like the faucet or the countertop. A low allowance makes the total look small, then you blow past it at the showroom and the bid balloons. Ask what grade each allowance assumes.

  • Labor: Is it a flat number or broken out by task? Flat numbers are easier to pad.
  • Markup: Most contractors add 10 to 20 percent for overhead and profit. That is normal. A number with no markup line usually has it baked in somewhere you cannot see.
  • Contingency: A 5 to 15 percent buffer for surprises is reasonable on a remodel. A 30 percent buffer means they are nervous, or padding.

Read the exclusions out loud

The fine print is the most honest part of a quote. Exclusions are the work the contractor is deliberately not doing, and they are how a low bid stays low.

Common ones: permit fees, debris hauling, painting after the trade work, electrical upgrades, and anything behind a wall. If the $9,400 bid excludes the subfloor and the $14,800 bid includes it, those are not the same job, and you should stop comparing their totals as if they were.

What a complete bid includes Red flags to question
Itemized labor and materials One lump sum with no breakdown
Stated allowances with grade noted Suspiciously low allowances, no grade
Permits and disposal listed Both quietly excluded
Clear payment schedule tied to milestones Large deposit, over 30 percent up front
Written exclusions section No exclusions listed at all
Start date and rough timeline "We'll fit you in" with no dates

Question the gap before you pick

Once the bids are normalized and the exclusions are out in the open, the spread usually tightens. Now you can ask real questions instead of vague ones.

Call the high bidder and the low bidder. Ask the high one what their number buys that the others do not. Ask the low one what happens if they hit rot or old wiring behind the wall. The answers tell you who has actually thought the job through.

A bid that comes in 30 percent under the other two is not a deal, it is a question. Either they missed something in the scope or they plan to make it up in change orders. Find out which before you sign, not after.

This is the moment to run through your questions before hiring a contractor, covering licensing, insurance, references, and how change orders get priced. The bid tells you the cost, but those questions tell you whether the number will hold.

Decide on value, not just price

The right pick is rarely the cheapest and rarely the most expensive. It is the bid that covers the full scope, lists its assumptions honestly, and comes from someone who answered your questions without dodging.

For a full kitchen remodel cost breakdown, the gap between bids can run $15,000 or more, and almost all of it traces back to allowances and exclusions you can now see. When two bids cover the same work and land within 10 percent, pick the person you trust to show up. That trust is worth more than the difference.

The quick version: Write the scope, get three bids on it, force them onto one sheet, read up from the line items, drag the exclusions into the light, then choose the most complete bid rather than the smallest number.

Frequently asked questions

How many quotes should I really get?

Three is the practical minimum. It gives you a middle and two edges, so you can spot the outlier and understand why it sits where it does. For very large projects, a fourth bid is worth the extra week.

Is the lowest bid always a bad sign?

Not always, but it is always a question. A low number can mean lean overhead, or it can mean missing line items and skipped exclusions. Normalize the bids onto one sheet and the reason the low one is low usually becomes obvious.

What is an allowance and why does it matter so much?

An allowance is a placeholder dollar amount for something you have not selected yet, like tile or a vanity. A low allowance shrinks the headline total, then you overspend it at the store. Always ask what material grade each allowance assumes.

Pull the bids apart before you let anyone start swinging a hammer. Match the line items, read the exclusions out loud, and ask the high and low bidders to defend their numbers. Do that, and the quote stops being a mystery and starts being a plan you actually understand. That is the difference between budgeting a project and getting surprised by one.
