What Should You Ask a Driveway Repair Contractor?
Ask whether the damage is a surface problem or a base problem and how they determined that, what caused it, whether the repair will last or is only delaying replacement, and what the labor warranty covers, typically 1 to 2 years. Driveway repair hinges on an honest diagnosis and a repair approach matched to the actual cause, so those answers are what get you an accurate assessment and accountability if the work fails early.
Is This a Surface Problem or a Base Problem?
This is the most important diagnostic question in driveway repair. Surface problems, such as hairline cracks that have not widened or displaced, edge crumbling without base involvement, and oxidation or surface raveling, can be handled with surface-level repairs. Base problems, including alligator cracking, slab settling, rutting along vehicle paths, and drainage failure from settled grade, require addressing the base before or instead of the surface. (For more on this, see Hidden Costs of Driveway Repair.)
Surface damage is visible; base damage is not. Ask specifically whether the contractor evaluates base condition as part of the assessment and how they do it. An experienced contractor examines crack patterns, probes for base softness, assesses settlement patterns, and explains what they found. A contractor who quotes surface repair without ever assessing the base is not giving you a complete picture, and a repair that treats only the surface over a failed base will not last.
What Caused the Damage, and Will the Repair Address It?
Ask specifically what caused the damage being repaired, then ask whether the proposed repair addresses that cause or only the symptom.
- Drainage failure: if water is undermining the base, surface crack filling does not prevent recurrence. The grade or drainage has to be corrected alongside the repair.
- Tree root intrusion: crack repair does not stop the roots. The root source has to be addressed or the heaving returns.
- Base failure from poor original installation: surface repair is not the right investment; a patch over failed base fails again within a season or two.
Will the Repair Last, or Am I Just Delaying Replacement?
Ask directly: given the driveway’s age, condition, and the specific repair proposed, is this likely to last 5 or more years, or to need repeat repairs within 1 to 2 years? An honest contractor answers realistically based on what they observed. One who promises the repair will last without qualification, regardless of the driveway’s actual condition, is prioritizing the sale. (For more on this, see What Affects the Cost of Driveway Repair?.)
Ask the repair-or-replace question the same way. A contractor recommending full replacement should explain the specific conditions that make repair inadvisable. One recommending repair on a clearly failing driveway is not serving your interest. Asking two or three contractors the same question and comparing their recommendations produces the most reliable assessment. (For more on this, see How to Find the Best Driveway Repair Contractor.)
Driveway Repair Cost at a Glance
Costs below are for a standard two-car driveway. Emergency or same-day repairs carry a 25 to 50 percent premium over scheduled work.
| Repair | Professional cost | Notes |
|---|---|---|
| Crack filling (hairline to 1/2-inch) | $175 to $300 per service call | DIY materials cost $20 to $50; the most cost-effective maintenance you can do |
| Edge repair | $200 to $650 | Depends on linear footage; cut back to sound material and patch with hot mix or concrete |
| Asphalt pothole patching | $250 to $600 per patch area | Hot-mix patching; DIY cold patch runs $10 to $20 per bag but lasts less than one season |
| Resurfacing (asphalt overlay) | $2,400 to $5,400 for 600 square feet | Appropriate when the surface has deteriorated but the base is sound |
| Mudjacking (concrete slab lifting) | $2,400 to $6,000 | Varies with slab count and lift required; typically 30 to 50 percent less than full replacement |
| Polyjacking (polyurethane foam lifting) | $3,000 to $8,000 | Slightly more than mudjacking, with faster cure time and less disruption |
Ranges here are national ballpark figures, not quotes. Actual pricing varies by region, home condition, materials, and contractor. How we source cost data.
Drainage correction, base reconstruction, and full replacement fall outside repair scope and are quoted separately after a site assessment.
Warranty, Written Scope, and the Red Flag Question
Ask for the labor warranty on the specific repair being performed: how long it covers, exactly what it includes, what would void it, and the claims process. A contractor who warrants repair work for at least 1 year is standing behind their diagnosis and execution, and 1 to 2 years is typical from an established company. The warranty should cover the repair performed, not just materials.
One more question quickly reveals a contractor’s quality orientation: ask what the most common reason is that projects like yours fail prematurely. A specific answer, such as inadequate base preparation on a driveway or the wrong spring selection on a garage door, shows someone who has thought about failure modes. A vague answer, or a claim that failures are rare with no explanation of how they are avoided, does not.
Price fairness is easiest to judge on a normalized basis. Compare crack repair by price per linear foot or per service call, resurfacing by price per square foot, and mudjacking by price per hole or per slab. Wide variation between bids usually reflects scope differences, such as the area being treated or whether base work is included, rather than genuine price competition.
Come to the visit prepared with the driveway’s age, any previous repair records, and these questions written down, then confirm the answers in writing. Get at least two or three quotes on the same defined scope, and verify general liability insurance and workers compensation before work starts. For any project over $500, written scope is non-negotiable: materials and preparation method, cost and payment schedule, timeline, warranty terms, and the process for scope changes. Tie payments to milestones rather than paying in full upfront, which is a red flag in any trade. The most common source of homeowner-contractor conflict is a scope item discussed verbally and never written down.
Frequently Asked Questions
Whether the damage is a surface problem or a base problem and how they determined that, what caused the damage and whether the repair addresses the cause, whether the repair will last or is just delaying replacement, and what warranty covers the repair labor.
Surface problems include hairline cracks that have not widened or displaced, edge crumbling without base involvement, and oxidation or raveling. Structural problems include alligator cracking, slab settling, rutting along vehicle paths, and drainage failure from settled grade. A contractor who can name the visual indicators they used is diagnosing correctly.
Base failure is the most common cause of recurring surface damage, and a repair that treats only the surface over a failed base will not last. An experienced contractor examines crack patterns, probes for base softness, and assesses settlement patterns before quoting.
Because some problems recur if only the symptom is repaired. Tree root intrusion returns if the root is not addressed, drainage failure returns if the grade is not corrected, and base failure under a patch returns within a season or two.
Ask the contractor directly whether the proposed repair is likely to last 5 or more years or to need repeat repairs within 1 to 2 years. An honest answer is based on the driveway's actual age and condition; an unqualified promise that it will last is a sales answer.
A labor warranty of 1 to 2 years from an established contractor, with 1 year the practical minimum, covering the specific repair performed rather than materials alone. Confirm what is covered, what would void it, and the claims process before approving the work.
Crack filling runs $175 to $300 per professional service call, edge repair $200 to $650, pothole patching $250 to $600 per patch area, and asphalt resurfacing $2,400 to $5,400 for a 600-square-foot driveway. Emergency or same-day work carries a 25 to 50 percent premium.
Get at least two quotes for the same defined scope. Compare crack repair per linear foot or per service call, resurfacing per square foot, and mudjacking per hole or per slab. Wide variation usually reflects scope differences rather than price competition, so normalize scope before comparing.
