A paver contractor contract should say, in writing, what is being built, what goes under the pavers, when work starts and finishes, how much you pay and when, and what happens if either of you wants to change something. If the paperwork is a one-page quote with a total and a signature line, you do not have a contract yet; you have a price. You can fix that before you sign, and it costs nothing.
I read two state agency pages (Maryland and Connecticut) and one advice page from PBS HomeTime for this. I have tied each term to how a paver job goes, because the important part of a patio is buried by day two. For finding and vetting the contractor first, read how to hire a paver contractor; this article starts where that one ends, at the signature line.
Eight lines every paver contractor contract needs
Here is the checklist, with where each item comes from.
| Term | What to look for | Source |
|---|---|---|
| Contractor identity | Name, address, license or registration number | Maryland and Connecticut both require it |
| Scope and materials | The work and the materials, itemised | Maryland: "a description of the work and the materials to be used" |
| Dates | Approximate start and completion dates | Maryland; Connecticut lists signing, start, completion and cancellation dates |
| Price | The total, clearly stated | Maryland |
| Payment schedule | Milestones, not calendar dates | PBS HomeTime |
| Change orders | A written procedure for changes | PBS HomeTime; Connecticut says changes must be in writing |
| Lien waivers | A promise to provide them for the contractor, subs and suppliers | PBS HomeTime |
| Signed copy | Both parties sign; you get the completed copy | Connecticut; Maryland wants it before work starts |
Which of these your state forces on the contractor varies, so look up your state's contractor board. Contract law is local, and nothing here is legal advice.
Name what goes under the pavers
The scope line is where paver jobs differ from other home work. A contract that says "install pavers" lets the cheapest possible base fit inside it, and you will not see the base once the sand and pavers are down.
Copy the base, bedding sand, edge restraint and joint-sand lines from the quote into the contract itself, with numbers. The published minimums are at least 4 inches of compacted base under a patio and 6 under a driveway on well-drained soil, plus 2 to 4 inches in cold or weak soil, and a nominal 1 inch of uncompacted bedding sand (ICPI Tech Spec 2). Our paver installation guide lists the whole sequence you can hold a crew to.
One extra clause that is my suggestion, not from any source I read: ask the contractor to photograph the finished, compacted base before the sand goes on, and send you the pictures. That turns the hidden layer into a visible one. Put the workmanship warranty length and what it covers in the same document; our paver warranty guide explains the difference from the manufacturer's warranty.
Tie payment to milestones, not the calendar
PBS HomeTime's advice is to pay at most "token earnest money" up front, then use a schedule of three payments of 30 percent at milestones, with the final 10 percent held until the punch list is finished. It is one writer's rule of thumb, not a law, but it shows the shape.
States may set the ceiling for you. Maryland says a contractor cannot accept more than one third of the contract price as a deposit and may not accept any payment until the contract is signed. Beyond the deposit, Maryland's page says the law does not control the payment schedule, so it is negotiable.
On a paver job the milestones are easy to map: excavation and base done, pavers laid, and joint sand and cleanup complete. That mapping is mine; the percentages in the diagram are PBS's example, so treat them as a starting point.
Say how changes get priced
Paver jobs change: the excavation finds soft soil, or you decide to extend the patio. Both are where a verbal "that will be a bit more" turns into an argument.
PBS HomeTime lists "a procedure for handling change orders" as a contract item, and Connecticut requires that the contract be in writing "including all changes and modifications." So the clause is simple: no extra work starts until the change, its price and any schedule effect are written down and signed by both of you.
Lien waivers and the final 10 percent
A lien waiver is a document in which the contractor, or a subcontractor or supplier, gives up the right to put a claim on your property for payment on that job. PBS HomeTime says the contract should state the contractor will provide them for himself and all subs and suppliers. I found no state waiver rules in the pages I opened, so ask your contractor board which forms apply, and get one with the final payment.
Hold the final 10 percent until the punch list is done. A punch list is the walk-through list of small fixes: a high paver, a missed joint. Once the contractor has been paid in full, that list tends to slide to the bottom of the schedule.
Your right to cancel
If you signed at home, some states give you a cooling-off period. Connecticut's page says the contract must carry a notice of the right to cancel before midnight of the third business day, and "there is no penalty if you cancel." Other states differ, so ask.
Read it twice, sign it once
My opinion: the base clause is the contract. Pavers are visible and will take care of themselves; the base is hidden, and the contract is the only thing that can make it visible later. If the contract names the work, the base, the dates, the payments and the change rule, you have protected most of what can go wrong on a patio job.
Take it home, read it twice, and sign it when the base line is in it.
FAQ
Do I need a written contract for a paver patio?
Many states require one for home improvement work; Connecticut requires it for every job. Ask for one even where it is optional.
How much deposit should I pay a paver contractor?
As little as possible. PBS HomeTime suggests token earnest money, if anything, and Maryland caps a deposit at one third of the price.
What is a change order?
A written, signed agreement that changes the scope or price after signing. Extra work should not start until it is on paper.
What is a lien waiver, and do I need one?
It is a document where a contractor, sub or supplier gives up a claim on your property for payment. PBS HomeTime says a contract should require them from the contractor and all subs and suppliers. Ask your state board which form applies.
Can I cancel a paver contract after signing?
Possibly. Connecticut gives three business days for covered contracts, but rules vary by state and sale type. Check your state's rules right away.
