  • What To Ask References
    Questions to Ask Previous Customers of a San Mateo County Concrete Contractor

    It’s best to choose a Diamond Certified concrete contractor because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a concrete contractor in San Mateo County and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified concrete contractor within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your concrete contractor. Keep in mind, though, that references provided to you by the concrete contractor 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 cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

    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.

    1. Would you recommend this concrete contractor to your friends and family?
    2. If you live in a smaller town such as Hillsborough, La Honda, Loma Mar and Millbrae, did you have to pay extra for their travel expenses to your home?
    3. Did they complete your concrete work on time?
    4. Did they show up at the designated time?
    5. If you need more concrete work done, will you choose this same company?
    6. Did the concrete contractor clean up after the work was completed?
    7. Did the concrete contractor keep you up to date on the status of your concrete work?

Keep a notebook for the information you collect so that you can quickly find any information that you need. You can also keep records of any questions or ideas you have.

    Meet with the concrete contractor. Using the notes that you have taken, accurately describe any concerns or questions that you have. Be very detailed and don’t be in a hurry. 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 concrete project and what it entails.

    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.

    Prepare Your Home for a San Mateo County Concrete Contractor
    Professional concrete contractors are able to handle the very small to very large aspects of their work. However, there are some things that you can do to prepare for them and to make their progress in concrete project go more smoothly. Doing these things may even cut down on their labor costs and can keep your home and belongings from being damaged.

    Keep your pets and children away from the area. Your concrete contractor will be focused on your project and should not have to watch out for your pets or children at any time. This not only prevents accidents and injury but also any expense that comes from accidents that may happen because of children and pets being in the way.

    Provide parking space and room for their work vehicles to maneuver. Concrete contractors have large vehicles that require more space than average. Contact your contractor before they begin building 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 the actual work begins.

    Trim plants and bushes that are in the way of your concrete area. 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.

    Remove any furniture or movable items from the area. Before they begin work on your concrete job, be sure the space is cleared and ready. It will slow down the project if your concrete contractor has to clear the area for you.
