Key Takeaways
- Ask about base preparation — it is the difference between a driveway that lasts 20 years and one that fails in 5.
- Verify licensing, insurance, and local references before signing anything. Delaware does not license paving contractors at the state level, so you must do your own vetting.
- Get everything in writing. A detailed contract protects you from scope creep, surprise charges, and “disappearing contractor” syndrome.
- Watch for seasonal scams — door-to-door “leftover asphalt” offers are the most common paving fraud in Delaware.
Choosing a paving contractor is one of the most consequential decisions you will make as a property owner. Get it right, and you have a smooth, durable surface that adds curb appeal and value for decades. Get it wrong, and you are looking at cracks, potholes, drainage problems, and an expensive do-over.
The challenge for Delaware homeowners? Unlike electricians and plumbers, paving contractors are not licensed at the state level in Delaware. That means the burden of vetting falls squarely on you.
This guide walks you through exactly what to look for, what to ask, and what should make you pick up the phone and call someone else.
Why Choosing the Right Contractor Matters More in Delaware
Delaware’s climate is rough on asphalt. We get freeze-thaw cycles all winter, heavy spring rains, and blistering summer heat — sometimes all within the same month. A driveway or parking lot that is not built to handle those conditions will start showing problems within the first few years.
Here is what happens when corners are cut:
- Thin asphalt (1 to 1.5 inches instead of the proper 2 to 3 inches) cracks under vehicle weight within 2 to 3 years.
- Skipped base preparation means the pavement has no stable foundation. Water pools, the surface sinks, and alligator cracking spreads fast.
- Poor compaction leaves air pockets in the asphalt that weaken the surface and let water penetrate.
- No drainage planning turns your driveway into a collection pond after every rain, accelerating base failure.
“The most expensive paving job is the one you have to pay for twice.” — Any Delaware homeowner who went with the lowest bid.
8 Questions to Ask Before You Hire
1. “How long have you been paving in Delaware?”
Experience matters, but local experience matters more. A contractor who has been working in Delaware for years understands our soil conditions, drainage challenges, and the specific ways our climate attacks asphalt.
Look for at least 5 years of verifiable local experience. Ask for the addresses of projects completed 3 to 5 years ago — you want to see how their work holds up over time, not just how it looks on day one.
Campos Mora Construction has been serving Delaware property owners for years, and we stand behind every project we complete.
2. “Are you insured? Can I see the certificate?”
This is non-negotiable. Any reputable paving contractor carries both:
- General liability insurance — protects you if the crew damages your property.
- Workers’ compensation insurance — protects you from liability if a worker is injured on your property.
Ask for a certificate of insurance (COI) directly from the insurance provider — not a photocopy the contractor hands you. A legitimate contractor will have no problem providing this.
3. “What does your base preparation process look like?”
This is the single most important question on the list. The asphalt surface you see is only the top layer. What is underneath — the base — determines how long your pavement lasts.
A proper base preparation in Delaware should include:
- Excavation of unsuitable soil (typically 6 to 8 inches)
- Compacted aggregate base (crushed stone, 4 to 6 inches)
- Proper grading for drainage away from structures
- Compaction testing to verify density
If a contractor cannot walk you through their base preparation process in detail, or if their answer is “we put the asphalt right on the ground,” move on.
4. “How thick will the asphalt be?”
For residential driveways in Delaware, the standard is 2 to 3 inches of compacted asphalt over a prepared base. Commercial parking lots that handle heavier vehicles should be 3 to 4 inches or more.
Be specific about this in your contract. A verbal promise of “it will be thick enough” means nothing if the finished product is an inch and a half.
5. “Can I see examples of your recent work in my area?”
A contractor with nothing to hide will gladly share addresses. Drive by those properties if you can. Look at:
- The smoothness of the surface
- How well the edges are finished
- Whether water drains properly after rain
- The condition of driveways that were paved 3+ years ago
Online reviews are helpful, but seeing the actual work with your own eyes is better.
6. “What is included in your quote — and what is not?”
A detailed quote should break down:
- Square footage of the paved area
- Depth of excavation and aggregate base
- Asphalt thickness
- Grading and drainage work
- Cleanup and disposal of old material
- Timeline and start date
Beware of quotes that are suspiciously low. Paving is a commodity business with thin margins. A bid that is 30% to 40% below everyone else almost always means corners are being cut somewhere.
7. “Do you provide a written warranty?”
Ask specifically what the warranty covers and for how long. Typical workmanship warranties in Delaware range from 1 to 2 years for residential paving. This should cover defects in materials and installation — cracking, sinking, and separation that are not caused by external factors.
A warranty that says “we guarantee our work” without specifics is not a warranty. Get the terms in writing.
8. “What is your payment schedule?”
Standard practice in the paving industry is:
- A deposit (typically 25% to 33%) to secure your spot on the schedule.
- The balance due upon satisfactory completion of the work.
Any contractor demanding full payment upfront or cash only should raise an immediate red flag. Reputable contractors have the working capital to purchase materials and pay their crew without needing your full payment in advance.
Red Flags vs. Green Flags at a Glance
| Red Flag | Green Flag |
|---|---|
| Shows up at your door with “leftover asphalt from another job” | You contact them after research or a referral |
| Cannot provide a certificate of insurance | Provides COI directly from their insurance carrier |
| Quote is verbal only — nothing in writing | Detailed written estimate with scope, materials, and timeline |
| Demands full payment upfront | Standard deposit with balance due on completion |
| No local references or examples of recent work | Happy to share addresses of projects completed 3+ years ago |
| Vague about base preparation and asphalt thickness | Explains exactly how deep they excavate and how thick the asphalt will be |
| Uses high-pressure tactics (“this price is only good today”) | Gives you time to review the quote and compare |
| No physical business address — just a cell phone number | Has a real business address, website, and professional presence |
Seasonal Scams to Watch For in Delaware
Every spring and summer, “paving crews” appear in Delaware neighborhoods offering deep discounts. The pitch is always the same: “We are doing a big job down the street and have leftover asphalt. We can pave your driveway for a fraction of the normal price.”
Here is the reality: reputable paving contractors order exactly the amount of asphalt they need for each job. There is no such thing as “leftover asphalt” in a meaningful quantity. What you get from these door-to-door operations is:
- Paper-thin asphalt sprayed over unprepared ground
- No base preparation whatsoever
- No compaction — they spread it and leave
- A surface that starts crumbling within months
- No way to contact them when problems appear
If someone knocks on your door offering a paving deal, the safest response is “no thank you” and a closed door.

What to Do If You Have Been Burned by a Bad Contractor
If you are reading this after a bad paving experience, you are not alone — and you do have options. If the surface is failing prematurely, a reputable contractor can assess whether it can be salvaged through patch repair or whether it needs to be removed and replaced.
In some cases, a properly applied sealcoat can extend the life of an aging surface while you plan for a full replacement. We are happy to evaluate your situation honestly and tell you what makes sense — even if that means waiting.
The Bottom Line
Hiring a paving contractor does not have to be stressful. Do your homework, ask the right questions, and trust your instincts. A good contractor will welcome your questions and answer them clearly and patiently. Anyone who gets defensive, vague, or pushy is doing you a favor — they are telling you everything you need to know.
