Guide
Most bad hiring decisions start with a fuzzy quote. When each pro is guessing at a slightly different job, their prices aren't comparable — and the "cheapest" one may simply have left the most out. Getting accurate, comparable quotes is a skill, and it starts before you ever pick up the phone.
The single best thing you can do is describe exactly what you want done, in writing, and give the same description to every provider. Note the dimensions, materials, finish level, and anything that must be included (haul-away, cleanup, permits). When everyone bids on the identical scope, the numbers finally mean something. Vague requests like "give me a price to fix up the yard" invite wildly different assumptions and wildly different prices. Taking ten minutes to write the scope down before you reach out pays for itself in clearer, more comparable numbers.
These words get used loosely, but the difference matters. An estimate is a ballpark that can change. A quote or fixed bid is a firm price the pro commits to for a defined scope. For anything sizable, ask for a written fixed quote and confirm what would trigger a change order — the surprises usually hide there.
Three is the sweet spot. One quote gives you no context; two can be misleading if one is an outlier; three lets you see the real market range and spot a bid that's suspiciously high or too good to be true. Try to gather them within a similar timeframe, since prices for materials and labor shift with demand and season.
Line the bids up side by side and check that each covers the same scope, materials, and quality. Look past the bottom-line number to what's included: warranty length, cleanup, permits, timeline, and payment schedule. A $400 gap often vanishes once you notice one bid includes premium materials or a longer guarantee. Ask every provider the same short list of questions so you're comparing on equal footing.
Walking into quotes already knowing the typical price range keeps you from anchoring to whatever the first pro says. Use the average service cost lookup to see low, typical, and high figures for your service in your state before you request bids — then any quote that lands far outside that range is worth a follow-up question.
A quote you can trust is specific. The Federal Trade Commission advises getting it in writing and making sure the estimate describes the work to be done, the materials to be used, a completion date, and the price (FTC). Before you sign a contract for a sizable job, the FTC also says it should list the contractor's name, address, phone number, and license number, along with any promises made in conversation. If a provider resists putting the basics in writing, treat that as information — it usually means the number is soft.

Comparing bids only works when you've asked everyone the same things. Run down this short list with each pro:
The answers often explain a price gap faster than the bottom-line number does.
A change order is a written amendment for when the scope shifts — you upgrade a finish, or the crew opens a wall and finds rot. Handled well, change orders are normal and fair. Handled badly, they're how a "low" bid becomes the most expensive one. Before work starts, agree in writing on how changes get priced and approved, so nothing lands on your bill without your signature. A suspiciously low bid sometimes counts on change orders to make up the difference later.
If you sign a contract at your home rather than at the contractor's office — common for door-to-door and in-home sales — federal law gives you three business days to cancel, in writing, for most sales of $25 or more. Crucially, that clock doesn't start until the seller hands you the completed contract and the cancellation notice; if they never do, the window to back out stays open (FTC Cooling-Off Rule). Knowing this takes the pressure out of a hard-sell pitch.
When you line up three bids, pay as much attention to the one that's far from the others as to the middle number. A quote 40% below the pack usually means something was left out — a smaller crew, cheaper materials, no permit, or a plan to recover the difference through change orders. A quote well above the pack isn't automatically a rip-off either; check whether it includes premium materials, a longer warranty, or a faster timeline. The goal isn't the lowest number — it's the bid whose scope and terms you understand completely.
How long is a quote good for? Ask — many pros hold a price for about 30 days because material costs move. Get the validity window in writing.
Is a verbal quote binding? Rarely, and it's nearly impossible to enforce. Always get a firm number in writing before work begins.
Should I share what others quoted? You don't have to. Sharing a competing number can help a pro sharpen a bid, but you'll compare more honestly if each price is built on the same written scope rather than on beating a rival.
