A resurfaced parking lot that cracks again in eighteen months costs more than the original job did. You pay for materials twice, you field calls from tenants about potholes, and you restart the bidding process on a tighter budget than the first time. Most of that pain traces back to one meeting: the first conversation with a contractor, where the wrong questions were asked, or the right ones were skipped. This guide gives you the exact questions to ask a parking lot contractor before you sign anything, and what a strong answer sounds like next to a red flag.
Quick answers, before you dial the phone:
- Confirm licensing, bonding, and both general liability and workers’ comp insurance. Ask for certificates directly, not a verbal promise.
- Get the estimate in writing, broken down by scope, materials, thickness, and exclusions.
- Ask what happens below the surface. Base repair and drainage matter more than the top coat.
- Confirm who handles ADA striping and signage, and whether it’s included or billed separately.
- Pin down the warranty in writing: what’s covered, for how long, and what voids it.
Is the Parking Lot Contractor Properly Licensed, Bonded, and Insured?
Start here, because everything else depends on it. Ask for a current state contractor’s license number, a certificate of insurance showing general liability and workers’ compensation, and proof of a surety bond if your state requires one for commercial paving work.
A strong answer includes a license number you can verify online and a certificate of insurance sent the same day, not “we’ll get that over to you.” If a contractor hesitates or says insurance “isn’t really necessary for a job this size,” treat that as a red flag. A slip-and-fall claim or an injured crew member can land on you, the property manager, if the contractor’s coverage doesn’t hold up.
How Much Direct Experience Do They Have With Properties Like Yours?
A contractor who mostly paves residential driveways handles a 40,000-square-foot retail lot differently than a firm that works on shopping centers every week. Ask how many commercial properties they’ve completed in the last two years, and ask specifically about properties similar to yours. Multi-tenant retail, apartment complexes, medical office parks, and industrial sites each bring different traffic loads and access constraints.
Experience with your property type also predicts how well a crew handles phasing. A contractor who’s never worked around occupied tenants may not think to ask about your busiest hours before blocking the only entrance.
Can They Provide Local References and Recent Project Photos?
Ask for three references from jobs completed in the last twelve to eighteen months, ideally properties you can drive by. Call them. Ask how the crew handled changes, whether the final invoice matched the estimate, and how the lot has held up since.
Photos matter too, but ask for photos from six months or a year after completion, not just the day the crew left. Fresh asphalt looks good on every job. The real test is how it looks after a winter of freeze-thaw cycles or a summer of full sun.
What Exactly Does the Written Estimate Include?
A one-page estimate that just says “asphalt paving, parking lot, $X” tells you almost nothing. Ask the contractor to break it down: square footage, asphalt thickness in inches, base repair scope, crack sealing, striping, ADA signage, and cleanup. Then ask what’s explicitly excluded.
This is where most disputes start. A property manager assumes drainage repair is included; the contractor assumes it’s a separate change order. Get it in writing before either side assumes anything.
What Process and Materials Will They Use, and Why?
Ask whether the job calls for a sealcoat, a mill and overlay, a full-depth patch, or a full reconstruction, and ask the contractor to explain why that’s the right call for your lot’s condition. A contractor who jumps straight to “we’ll just sealcoat it” without checking the base or the drainage first is treating a symptom, not the problem.
Ask about asphalt mix design, compaction standards, and minimum lift thickness. Ask what temperature range they need for placement. Hot-mix asphalt generally requires ground and air temperatures above roughly 50°F, which is why a reputable contractor won’t pave in the wrong conditions just to hit a deadline.
What’s Their Plan for Drainage, Grading, and the Base Beneath the Surface?
Standing water is usually a grading problem, not a paving problem. A contractor who repaves over it without fixing the slope just buys you a year or two before the same puddle comes back. Ask how they’ll check existing grade and drainage flow before they quote a fix. Ask what happens if they find a soft or saturated base once work starts.
You should ask about the subgrade too. Asphalt fails from the bottom up far more often than from the top down. A contractor who inspects the base, checks for soft spots with a proof roll, and calls out subgrade repair as its own line item is protecting your investment. One who skips straight to “we’ll just pave over it” is setting you up for an early callback.
How Will They Handle ADA Compliance and Striping?
Every commercial parking lot with public access has to meet ADA accessibility standards: a minimum number of accessible spaces scaled to total lot size, van-accessible spaces at a ratio of roughly one in six accessible spots, running and cross slopes no steeper than about 2 percent, and compliant signage height and placement. Getting this wrong exposes you to complaints and potential litigation, not just a failed inspection.
Ask directly whether ADA striping and signage are included in the scope, or billed as a separate line item. Ask who verifies compliance once the paint is dry. A contractor who can walk you through the accessible space count for your lot size, unprompted, has done this before.
Will They Use Subcontractors, and Who’s Accountable?
Many paving companies subcontract striping, sealcoating, or crack sealing to specialty crews. That’s normal. What matters is accountability. Ask which parts of the job, if any, go to a subcontractor, and ask who’s responsible if that portion fails: the general contractor you signed with, or the sub.
Get this in writing in the contract, not as a verbal assurance. If the general contractor won’t put subcontractor accountability in the contract, ask why.
What’s the Project Timeline, and How Will They Minimize Disruption?
Ask for a day-by-day schedule, not just a start and end date. Ask how the crew will phase the work if tenants, residents, or customers need parking access throughout the project. Including noise restrictions, curing time before the lot reopens to traffic, and whether work will be scheduled nights or weekends to reduce disruption.
A contractor who proposes phasing your lot into sections, with clear signage and temporary parking directions for each phase, is thinking about your tenants, not just the crew’s convenience.
What Warranty Do They Offer, and What Voids It?
Ask for the warranty length in writing: one year, two years, or longer, and ask exactly what it covers. A warranty on materials and workmanship is standard. A warranty against things you can’t control, like tree root damage or a burst water main under the lot, isn’t realistic to expect.
Ask what could void the warranty. Some contractors require specific maintenance, like sealcoating on a set schedule, to keep coverage active. If that’s the case, get the maintenance requirement spelled out in writing, not buried in fine print you find after a problem shows up.
What Are the Payment Terms and Change-Order Policy?
Ask about the deposit amount, the payment schedule, and what triggers a change order. A large upfront deposit with no milestone-based payments is a common red flag in commercial construction generally, not just paving.
Ask how change orders get approved. A strong contractor won’t add extra work to your invoice without your written sign-off first. If they can’t describe that process clearly, ask again before you sign anything.
Questions to Ask, at a Glance
| Question | Strong Answer Sounds Like | Red Flag Sounds Like |

The Real Cost of Skipping These Questions
The cheapest bid on paper is rarely the cheapest job once you factor in a warranty that doesn’t hold up, a subcontractor dispute mid-project, or an ADA complaint six months after the lot reopens. Every question above exists because a property manager, somewhere, learned it the hard way.
None of this has to slow the process down. A contractor who’s ready for these questions usually answers most of them in a single site visit, in writing, without you having to chase them down. Choosing the right parking lot contractor now saves you a second bidding process, and a second budget line, later.
Hiring the wrong contractor usually means cut corners, project delays, and surprise expenses down the road. You deserve honest answers about scheduling, safety, materials, and warranties before anyone sets foot on your property. Reach out today. We’ll happily answer all your questions so you can hire with complete confidence.
Frequently Asked Questions
How much does it cost to hire a parking lot contractor?
Cost depends on lot size, current condition, and scope. Sealcoating costs far less per square foot than a mill-and-overlay or a full reconstruction. Get at least three written, line-item estimates before comparing prices, since a low bid with a narrow scope isn’t actually cheaper once the exclusions surface.
How long does parking lot paving or sealcoating take?
A standard sealcoat job on a mid-size commercial lot often takes one to two days, including cure time before the lot reopens to traffic. A full mill and overlay can take several days to a week or more, depending on lot size and phasing.
How often should a commercial parking lot be sealcoated?
Most commercial lots benefit from sealcoating every two to three years, depending on traffic volume and climate. Waiting longer often lets small cracks turn into base failures, which cost far more to fix.
Do parking lot contractors handle ADA striping and signage?
Most full-service commercial paving contractors do, but not all include it by default. Confirm ADA striping and signage are named in the written scope, since it’s sometimes billed as a separate line item.
What insurance should a parking lot contractor carry?
At minimum, general liability insurance and workers’ compensation. Ask for a certificate of insurance directly from the contractor rather than taking their word for it, and confirm the coverage is active, not expired.
Can parking lot work be done without closing the whole property?
Usually yes, through phasing. Ask the contractor to propose a section-by-section plan so tenants, residents, or customers keep some parking access throughout the project.
What warranty is standard for asphalt paving work?
One to two years on materials and workmanship is common, though terms vary by contractor and region. Get the exact coverage, length, and any required maintenance in writing before you sign.
