    If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    Sample questions to ask references of local paving contractors include:

    • Would you recommend this asphalt stamping and paving contractor to your friends and family?
    • When you need this work done in the future, will you choose this same company?

    First, meet with the paving contractor. Use the notes that you have taken so you can accurately describe any concerns that you have. Be as detailed as possible and don’t be in a rush. It is as important for you to hear their suggestions and observations as it is for them to hear you. If you don’t understand something, ask for an explanation. You need to completely comprehend the plan and any problems or solutions.

    Be sure to get all estimates in writing before any work begins. The estimate should include an itemized list of the cost of supplies and the labor. Don’t ever sign a blank estimate.

Contact your contractor before they begin and ask them how many parking spaces they need and how much room they need for oversized vehicles. It is also helpful to walk through the area with your contractor so any hazards or clearance issues can be pointed out before installation of your asphalt and stamping.

    Trim plants and bushes that are in the way. You can save money and time by preparing the area for building by trimming or removing any plants, trees or bushes that are in the way. Ask your contractor what they recommend and the amount of space they require.

Corrective maintenance is required less often but is necessary when there is excessive cracking or other problems.

Q: Are the estimates for asphalt and paving stamping free?
A: Many asphalt and paving companies will provide you with a detailed estimate at no charge. Others may offer to apply estimate fees to the final job if you hire them. While still others charge a fee for asphalt pouring services. Talk to the asphalt company representative about their estimate policy.

Q: How do I clean my asphalt and paving?
A: It needs to be flushed with water to remove sand and dirt or other abrasive materials. Abrasive materials decrease the life of sealers.
