What a patio estimate should include

A lump-sum price tells you nothing. The useful ones are itemized enough that you know what you're buying.

A useful estimate names the things that decide the job: how much is excavated and hauled away, the base depth in inches, which stone and pattern, edge restraint, a stated drainage plan for your grade, and any steps, seat walls and lighting broken out separately.

It also names when they start and who's on site doing the work. Those two lines tell you a lot about how the job will actually run.

A real estimate reads like a short set of decisions, not a single number. What is coming out, how deep the dig goes, how thick the base is, what the stone is, how the edges get held, and where the water goes. If a bid skips all of that, the number is not a price, it is a guess that gets adjusted later.

The other thing a good estimate does is set expectations on time and access. When the dig starts, when the stone lands, how long the yard is unusable, and whether a truck can get close enough to tip stone where it is needed. Access decides a lot of cost in town lots, and it is better to settle it on paper than on the day.

A fair estimate should tell you what you are getting in plain terms: roughly how many square feet, what stone, how deep the dig, whether there is a step or a wall involved, and how long it should take. You should not have to reverse-engineer any of that from a single number. If the whole quote is one line and a total, that is not a sign of confidence; it is a sign that nothing was looked at closely.

It is also reasonable to ask what happens if the job runs into something unexpected, like a hidden stump, a buried footing or a soft spot under the dig. The honest answer is that the price can change, and the trustworthy version of that is a quote that says so up front and tells you how it would be handled. A number that pretends no surprises are possible is the one to be careful with.

Compare quotes on the same scope, not on the total. Two bids only mean something if they cover the same dig, the same base depth, the same stone, and the same cleanup. Ask each crew to break the job into the same parts, then set them side by side. The lowest total on a thinner base is not the cheapest quote, it is a smaller job wearing the same label.

• Excavation and how much material leaves the site
• Base depth, in inches, not "to code"
• Which stone, and the actual pattern or size
• Edge restraint: the hidden piece that keeps the border from spreading
• Drainage plan for your grade, stated plainly
• Steps, seat walls and lighting broken out separately
• When they start, and who's on site doing it

The tell: a bidder who asks about your grade and how you'll use the space is planning a build. One who only asks how you want it to look is quoting a surface.
