Sealcoating protects asphalt surfaces against water, oil, and UV damage, extending the life of your driveway or parking lot. Finding a reliable sealcoating contractor requires research, careful comparison, and asking the right questions. This guide walks you through each step so you can make an informed decision and invest in quality service that stands the test of time.

Assessing Credentials and Experience

Licensing and Insurance

A professional contractor should hold appropriate state or local licenses. Insurance—both general liability and workers’ compensation—ensures you won’t be held responsible for accidents or property damage. Always ask to see copies of these documents before signing a contract.

Track Record and Portfolio

Comparing Services and Materials

Not all sealcoating services are created equal. Examine the following details:

  1. Type of Sealant
    • Coal-tar vs. asphalt-based: Understand environmental and durability differences.
    • Additives: Some include polymers for extra flexibility and longevity.
  2. Equipment and Application Method
    • Spray versus squeegee: Each has trade-offs in terms of finish quality.
    • Surface prep tools: Proper crack filling and pressure washing prevents premature failure.
  3. Warranties and Follow-Up
    • Service guarantees: Coverage for peeling or discoloration.
    • Maintenance plans: Does the contractor offer annual check-ins?

Getting and Evaluating Quotes

Request detailed, written estimates from at least three contractors. A comprehensive quote should include:

Compare apples to apples by ensuring each quote covers the same services and materials. Beware of dramatically low bids—they may indicate shortcuts or inferior sealants.

Red Flags to Watch Out For

FAQs

How long does sealcoating last?

On average, quality sealcoating lasts between two and five years, depending on traffic volume and weather exposure. Regular maintenance can extend this lifespan.

What is the best time of year for sealcoating?

Late spring through early fall offers warm, dry conditions ideal for proper curing. Avoid cold or rainy periods, as moisture can disrupt the sealant’s bond.

Can sealcoating be applied over cracks?

Minor cracks should be filled with crack sealant before the sealcoating process. Proper crack repair is essential to prevent water infiltration and further deterioration.

Is sealcoating environmentally friendly?

Modern sealants often use petroleum-based products with additives to reduce runoff and volatile organic compounds (VOCs). Ask contractors about eco-friendly options if you have environmental concerns.

Conclusion

Choosing the right sealcoating contractor involves verifying credentials, comparing materials and services, and reviewing reputable feedback. By following these steps and asking targeted questions, you’ll secure a contractor who delivers lasting, high-quality protection for your asphalt surfaces—ensuring a smooth finish and peace of mind.
