  • What To Ask References
    Request Information From Previous Customers of Asphalt Stamping and Paving Contractors

    It is best to choose a Diamond Certified asphalt company because all certified companies have passed an in-depthratings process that most other companies can’t pass. If you want quality from an asphalt stamping and paving contractor in San Mateo County, you can have confidence choosing a Diamond Certified company.

    Keep in mind, though, that references provided to you by local asphalt stamping and paving contractors are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are often hand-picked instead of randomly selected from all the company’s customers.

    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?
    • Did they clean up after they completed the job?
    • Did they keep communication with you up to date on the status of your project?
    • If you live in a smaller town or rural San Mateo County, did the paving/asphalt stamping contractor charge you an extra fee to come to your home?
    • Were you satisfied with the service from this asphalt stamping and paving contractor?
    • What type of asphalt stamping and paving were used?

    If you don’t understand something, ask now. You need to completely comprehend the plan and any problems that may come up and the possible solutions.

    Remove any outdoor furniture or movable items from around the area where the asphalt stamping and paving contractor will be working. Before they begin work, remove anything that may be in the way such as barbecues. The more you do the more quickly they can get to work.

    Provide parking space and room for work vehicles to maneuver. Some asphalt stamping and paving contractors have large vehicles that require more space than average. Contact your contractor before they begin and ask them how many parking spaces they need and how much room they need for oversized vehicles.

    Keep your pets and children away from the area. Your asphalt stamping and paving contractor will be focused on installing your asphalt and stamping and should not have to watch out for your pets or children at any time.

    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.

A: It needs to be flushed with water to remove sand and dirt or other abrasive materials. Abrasive materials decrease the life of sealers.
