What should a concrete driveway estimate include?

A concrete driveway estimate should state what will be removed, how the new driveway will be built (concrete strength, thickness, reinforcement and stone base), how drainage will be handled, what the warranty covers, and how the contract deals with payment, extra work and unforeseen ground conditions.

Marshall Construction, a concrete driveway contractor in Delaware based in Newark, emails a written estimate within 24-48 hours of the estimate visit, and the contract that follows confirms the estimate pricing. The checklist below follows what the company's packages and contract specify.

Checklist: how the driveway will be built

Scope
The areas being replaced, such as the driveway, apron or a connecting walkway
Demolition and removal
Tear-out and disposal of the existing driveway (included in every Marshall Construction package)
Concrete strength
The PSI rating (4,000 or 4,500 PSI in Marshall Construction's packages)
Thickness
4, 5 or 6 inches, by package
Reinforcement
Fiber mesh, and whether 8-gauge wire is added
Stone base
The depth of compacted stone (4 to 6 inches, by package)
Grading and drainage
How the new driveway will be graded so water drains away
Cleanup
Topsoil and seeding of disturbed areas

Most of these items are part of what affects the cost of a concrete driveway, and Marshall Construction publishes the figures for each package on its residential concrete services and driveway packages page. At Marshall Construction, most driveway jobs go from demolition to cleanup in a single day, and the estimate and contract steps before that day are also part of how long driveway replacement takes.

Checklist: warranty

Warranty length
1, 3 or 5 years at Marshall Construction, by package
Measurable coverage
No visible puddles lasting more than 12 hours, no settling greater than 3/4 inch, no cracks exceeding 1/4 inch
Written exclusions
A written list of exclusions

The three limits cover puddling, settling and cracking, the same problems that lead homeowners to look at options for a cracked or sinking driveway. Marshall Construction's full terms and exclusions are set out in what a concrete driveway warranty should cover.

Marshall Construction's published exclusions include displacement or chipping between new and existing concrete, a point that also comes up with garage slabs and concrete pads when a new pad is added onto an existing one.

Checklist: contract and payment

Signed contract
A signed contract that confirms the estimate pricing and spells out terms
Payment schedule
At Marshall Construction, half is invoiced after signing and paid before work starts; the final invoice follows completion
Disclosed fees
Such as credit card fees
Unforeseen conditions
How unforeseen conditions below ground, such as ground that will not hold compaction, are handled, and when the homeowner is told
Extra work
How extra work requested during the job is priced

Marshall Construction's office sends the contract through DocuSign, part of how the company runs a project. If a homeowner asks for extra work during the job, such as two more sidewalk blocks, the crew stops, gives the additional cost, and the work appears on the final invoice. Invoices can be reviewed and paid online.

A driveway quoted together with concrete patios, walkways and steps goes on one estimate and one contract, which is how combining several concrete projects with one contractor works at Marshall Construction.

A ballpark price before the site visit

Homeowners who want a starting number can use Marshall Construction's online Quick Quote, sending photos and measurements with a name, email, phone number and address. Photos matter because access issues, such as a tight backyard or a fence that has to come down, change the price. The on-site estimate is free, and Kyle Marshall typically visits the same week.

What to ask during the estimate visit

Kyle Marshall explains thickness, reinforcement and base at the estimate, since many homeowners have not bought a concrete driveway before. He also checks water runoff, whether the ground holds compaction, and whether the site needs extra reinforcement. Homeowners can ask how each of these affects the package he recommends. Asking every bidder the same questions is the core of choosing a concrete driveway contractor.
