Getting three flooring quotes is standard advice, and good advice, but it only helps if you actually compare them the same way. Two contractors can hand you two numbers that look close on the total line and describe completely different projects. One bid might include furniture moving, old-floor tear-out, new transitions, and sales tax; the other might cover materials and labor only and leave the rest to you. This guide walks through how to normalize flooring bids so you are comparing the same scope, not just the same dollar amount.
Why flooring bids look so different from each other
Flooring is sold and installed in pieces. There is the material itself, the underlayment or vapor barrier underneath it, the prep work that makes the subfloor ready, the trim and transitions that finish the edges, the labor to move what is in the room, and the disposal of what comes out. Every contractor decides where to itemize those costs and where to fold them into a single number. Some quote material-plus-installation only because that is what their software prints. Others give a turnkey price. Neither is dishonest, but they are not directly comparable until you break them apart.
Step one: make sure everyone is pricing the same square footage
Start with the measurement. Ask each bidder how many square feet they are pricing and how they measured it. Flooring is usually ordered with a waste factor on top of the net room area to cover cuts, especially with tile and wood-look planks laid on a diagonal or in a pattern. A bid that prices 1,000 square feet and a bid that prices 1,080 square feet may both be right, because one may include an 8 percent waste factor and the other may not. Get the net area and the waste factor separately so the unit-cost comparison is fair.
- Net room area (length times width, minus cabinets and permanent fixtures)
- Waste factor added for cuts, pattern matching, and replacement stock
- Spaces that are measured but installed differently, like closets or stairs priced per step
- Whether leftover material is left with you as attic stock for future repairs
Line items: compare them one row at a time
Once the area is consistent, lay the bids out side by side and compare line by line. If a line is missing from a bid, that does not mean it is free; it usually means you are expected to handle it or pay extra later. Ask the bidder to price anything that is blank so you are not surprised.
| Line item | Why it matters | What to confirm |
|---|---|---|
| Material (brand, collection, thickness, wear layer) | Specs drive price and durability | Same SKU and color across every bid |
| Underlayment or vapor barrier | Required under most floating floors and over concrete | Type, thickness, and whether it is included |
| Subfloor prep and leveling | Flatness limits are set by the manufacturer | Allowance or fixed price, plus flatness tolerance |
| Old floor removal and haul-off | Tear-out is labor-intensive and messy | What is removed, where it is dumped, and the fees |
| Transitions and trim | Required at every doorway and height change | Style, material, and the linear footage priced |
| Furniture and appliance moving | Often excluded or charged per piece | What they will and will not move |
| Sales tax and disposal fees | Can add up to a lot on a whole-home job | Listed as a line item, not buried in labor |
| Warranty | Separates workmanship from product coverage | Length, what it covers, and who honors it |
Prep work is where bids diverge the most
Subfloor preparation is the line item that swings estimates the most, and it is the one homeowners understand least. Manufacturers publish a maximum variation, commonly 3/16 inch over 10 feet, and a moisture range for the substrate. A contractor who actually checked the subfloor will price prep based on what they found. A contractor who did not check may quote low and add a change order later, or quote high to protect themselves. Ask every bidder the same questions so the prep assumptions match.
Questions every bid should answer
- Did you measure subfloor flatness, and what did you find?
- Did you test concrete for moisture, and with what method?
- Is leveling compound included, or priced as an allowance?
- Who repairs damaged subfloor if it is discovered during tear-out?
Tip: A bid that is 20 to 30 percent lower than the others almost always skipped the prep line or the tear-out line. Ask that bidder to add them back in before you decide.
Payment terms and change orders
Price is only part of a bid. The terms around that price matter just as much. The FTC advises consumers never to pay the full project amount up front, and notes that some states limit how large a down payment a contractor may legally request. Read each bid's payment schedule and change-order language before you compare totals.
- Down payment amount, and whether your state caps it
- Milestone payments tied to delivery of material and completion of prep, not just a calendar date
- Final payment held until you have inspected the finished floor
- A written change-order process so any added work is priced and signed before it happens
A simple bid-comparison worksheet
Use a worksheet like the one below to force every bid into the same shape. Fill in each cell, and where a bidder left something blank, ask for the number before you decide.
| Comparison row | Bid A | Bid B | Bid C |
|---|---|---|---|
| Total price | |||
| Net square footage priced | |||
| Material cost per sq ft | |||
| Removal and disposal included? | |||
| Furniture moving included? | |||
| Transitions and trim included? | |||
| Subfloor prep included or allowance? | |||
| Sales tax included? | |||
| Warranty (workmanship / product) | |||
| Payment schedule |
The lowest bid is not always the best bid
Once every bid is normalized to the same scope, the right choice often becomes obvious. A bid that is genuinely lower for the identical scope is a real win. A bid that is lower because it skips tear-out, prep, or trim is just a smaller project dressed up as a cheaper one. The FTC specifically warns against automatically choosing the lowest estimate and recommends asking for an explanation when there is a large difference between quotes.

Frequently Asked Questions
How many flooring bids should I get?
Aim for at least three written bids for any meaningful project. Three gives you a range, reveals who is thorough, and lets you spot an outlier. The FTC recommends getting multiple estimates rather than automatically accepting the lowest one.
Why do flooring estimates vary so much?
Estimates vary because contractors itemize differently and make different assumptions about prep, tear-out, and trim. One bid may include subfloor leveling, furniture moving, and disposal while another prices only material and labor. Normalize the scope before you compare totals.
How much should I pay as a deposit for flooring?
It depends on your state, but never pay the full amount up front. Some states cap the down payment a contractor can request. A common structure is a deposit for materials, a milestone payment when prep is done, and the balance after you inspect the finished floor.
What is a change order in a flooring project?
A change order is a written, signed agreement that adds or changes work after the contract is signed, for example repairing rot discovered during tear-out. A good bid or contract states how change orders are priced and approved before the extra work begins.
