How to Read a Hardscape Quote

Every stage that costs real money and decides the outcome should be its own line, with a quantity or a specification beside it.

Not every contractor prices line by line, and that is fine as long as the specification is written down. What matters is that you can see what is being built underneath the part you will look at.

Enough detail that another contractor could build the same thing from it.

ICPI Tech Spec 2, the industry construction standard for concrete pavers, gives the reference points: at least four inches of compacted aggregate base for a patio over well-drained soil, at least six for a residential driveway, two to four inches more on wet, weak or cold ground, compaction in lifts of four to six inches with a suitably sized plate, and about an inch of bedding sand on top. A quote that gives a base depth below those figures, or no depth at all, is telling you something.

For retaining walls, the reference is the NCMA's segmental wall guidance: a compacted leveling pad extending past the block front and back, the bottom course buried, at least twelve inches of drainage gravel behind the block, a drain pipe at the base and geogrid where the design needs it. Any wall over four feet in Bentonville or Fayetteville also needs an Arkansas-licensed engineer, and that should be on the quote.

You do not need to become an expert. You just need to see those items named, so you can ask about any that are missing.

The ones that move risk onto you without telling you what it costs: rock, spoil, permits, utilities and reinstatement.

Rock. On the Springfield Plateau, the Boone Formation's limestone and chert can sit close to the surface. A quote that excludes rock excavation entirely has moved that risk to you. A good quote says how rock will be handled and how it is priced if found.

Spoil disposal. Excavated material has to go somewhere, and on a sizeable job that is a lot of truck loads. If it is excluded, you own a pile of dirt.

Permits. Know who applies and who pays. Some cities also need a separate permit for work in the public right-of-way; in Bentonville any work in a street, curb, gutter or sidewalk needs a right-of-way permit through eTrakit, with five business days for review.

Utilities. Buried lines must be located before digging. Ask who arranges it and what happens if a private line, such as irrigation or a garden light feed, is found.

Reinstatement. Machinery gets to the back garden somehow. Ask what state the route will be left in.

Line the quotes up by specification rather than total, and the gap usually explains itself.

Nine times out of ten the difference is excavation depth, base thickness and whether drainage is there at all. The second most common difference is scope: one quote includes steps, edging and lawn repair, and the other quietly does not.

If one quote is dramatically lower and the specification looks identical, ask both contractors the base and drainage questions directly and compare the answers rather than the paperwork. The difference usually surfaces immediately.

Be realistic about what a low number means. Nobody works for free. A price well below the others is buying something back somewhere, and it is almost always the part you cannot see.

A fixed price is what you pay; an allowance is a placeholder that moves when the real choice is made.

Allowances are normal for things that have not been chosen yet, such as a specific paver, a grill model or light fittings. They let a quote be finished before every decision is made. The risk is an allowance set unrealistically low to make the total look better, which then rises once you choose what you actually want.

When you see an allowance, ask what it would buy. If the answer is the cheapest product in the range, and you have been looking at the top of it, adjust the number in your own head before comparing.

Contingency for rock or unknown ground is a different thing, and on this ground it is honest. The quote should say how it is triggered and how it is priced, so it cannot become a blank cheque.

With dimensions and a method, because these are the lines where scope quietly shrinks.

A retaining wall line should give the height and length, the block or stone, the footing or leveling pad, the drainage behind it and whether an engineer is involved. Height matters most, because over four feet in Bentonville and Fayetteville the wall needs an Arkansas-licensed engineer and a permit, and that should be priced rather than discovered.

A covered structure should say attached or freestanding, the roof type, the post and footing details, and who handles the building permit. Rogers, for example, lists covered patios by name among the work that needs one.

Services should be listed by run: gas from the meter to the grill, power from the panel to the kitchen, water to the sink with a drain-down point, and any spare conduit. If a service is shown as a lump sum, ask where it runs from and to. Distance is the cost, and it is easy to underestimate on a drawing.

Because the lines that move most, excavation, base and drainage, depend on things you can only see on the ground.

Slope, where water runs in a storm, how machinery gets to the back, whether the soil is clay or fill, whether there are signs of rock, where the utilities and easements are. None of that shows in a photo or an aerial view. A quote built without it is built on assumptions, and assumptions become change orders or corners cut.

A good site visit also produces the brief: how you want to use the space, what matters and what does not, and the budget you have in mind. The quote that follows should read like the answer to that conversation.

A deposit to secure the schedule and materials, then stages tied to progress, with the final payment after the work is complete and walked through.

A deposit is normal. What is not normal is a large payment up front with no materials ordered, no start date in writing and no drawing. Stage payments should be tied to visible milestones, such as the base finished and inspected, the surface laid, the structure complete, rather than to calendar dates that arrive whether or not the work has.

Hold the last stage until you have walked the finished job with the contractor, the site is cleared, and any permits that needed a final inspection have had one.

Financing changes how you pay, not what the job should cost, so compare the specification first and the payment terms second.

Gallardo Custom Builds offers financing through Acorn Finance, which lets you look at options from lenders before committing. Our projects start around seven and a half thousand dollars, and the right number for yours comes out of a site visit, not a phone call.

Whoever you hire, make sure the quote you finance is the complete one. Financing a thin quote and then paying for the missing drainage or the rock out of pocket is the worst of both.

One you could hand to another contractor and get a comparable price back.

For a typical paver patio that means: the area and outline on a drawing; the excavation depth and where the spoil goes; the base material, compacted thickness and number of lifts; the bedding sand; the edge restraint; the slope and where the water goes, with any drains shown; the paver by name, colour and pattern; the joint material; any steps, walls or services with their own lines; who handles permits; what happens if rock is found; how the lawn and access route are left; and a payment schedule tied to progress.

That is not an unusual list. It is simply what the contractor had to decide to price the job, written down so you can see it.

A single line called “patio”, a price given without a site visit, or exclusions you only find out about after you ask.

• No base depth or material named.
• No mention of drainage on a site where water clearly sits.
• Retaining walls with no heights, or no engineer on a wall over four feet.
• Rock, spoil, permits or reinstatement excluded without a price.
• A start date that depends on a large payment.

A contractor who has planned the work can describe it. One who has priced a picture of it cannot, and the quote usually shows which one you are dealing with.
