Carlos Barbosa: Paver Protégé

By James Florence, Diamond Certified Resource Reporter

PINOLE — When asked about the origin of his career in the paver industry, Carlos Barbosa says it all started with a casual friendship. “Before I started working with pavers, I worked for my dad doing excavation and debris hauling. In 2009, I met Alberto Lisboa, who was installing pavers as a subcontractor on a jobsite I was on, and we became friends. A few years later, Alberto started his own paver business and told me I should come work for him—an opportunity I gladly accepted. He thought I’d be good at sales but felt I first needed to get an education in the industry. For the next three years, I worked alongside Alberto and he taught me everything I needed to know. Finally, after acquiring the requisite knowledge and experience, I moved into the sales department.”

Today, as sales manager of Brasmerica Pavers System, Carlos says his favorite part of his job is seeing the end result of each project. “I enjoy every step of the process, from meeting with clients to helping them with designs. However, my favorite part is actually seeing the design come into being, because that’s when you know you’ve accomplished your goal.”

A resident of Pinole (where he lives with his wife, Sandra, and their two children), Carlos spends his free time on a variety of pastimes. “I enjoy watching sports, especially soccer, hanging out with friends and family, and traveling,” he details. “Due to the demands of work, I don’t go on a lot of long trips, but I do take two or three mini-vacations each year. I like going to Las Vegas, South Lake Tahoe and other destinations that are near enough to make a short visit worthwhile.”

In his life and career, Carlos espouses the value of a respectful attitude. “Respecting others is the most important thing to me,” he affirms. “In regard to my job, this means being respectful of my clients and their homes. When you go into someone’s home and work on their property, you have to respect their space. You also have to remember it’s their project, and they’re entitled to a good value for the money they’re paying you. I show each client respect by making sure they’re served well and receive a high-quality final product.”

When asked the first thing he’d do if he were to retire tomorrow, Carlos says he’d pay a visit to his home country. “I would take a trip to Brazil, which is where I’m from. I’d probably spend a month or so just visiting the family and friends I have there.”

  • What To Ask References
    Interview Questions For Previous Customers of a Napa County Paving Stone Contractor

    It’s best to choose a Diamond Certified paving stone 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 paving stone contractor in Napa 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 paving stone 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 paving stone contractor. Keep in mind, though, that references provided to you by the paving stone 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 paving stone contractor to your friends and family?

    2.     When you need this work done in the future, will you choose this same company?

    3.     Did they clean up after they completed the job?

    4.     Did they keep communication with you up to date on the status of your project?

    5.     If you live in a smaller town such as Rutherford and Angwin, did you have to pay extra for their travel expenses to your home?

    6.     Were you satisfied with the service from this paving stone contractor?

    7.     What type of paving stones were used?

    8.     Did they finish the work on time?

    9.     Did they show up for work on time?

  • How To Work With
    Reviewing Your Contract With a Paving Stone Contractor in Napa County

    Paving stones do not have to be a major financial setback. Plan your budget and stick to it. After you have found a Napa County paving stone company in Napa County that you can trust, you will have peace of mind having your paving stones installed.

    First, meet with the contractor. Use the notes that you have taken so you can accurately describe any concerns that you have. Be detailed 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. Ask for an explanation if there is anything you don’t understand. 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.

    Getting Your Contract and Signing With a Paving Stone Contractor in Napa County
    When you completely satisfied with the information you have received from your Napa County paving stone contractor and they have answered all of your questions, sign the contract. Be sure that they have a phone number where you can always be reached.

    Expect the contractor to stay within the estimate. However, if the actual paving stone costs exceed the original amount of the estimate, the contractor must get your approval before moving ahead.

    Getting Ready for Your Paving Stone Project in Napa County
    Professional paving stone 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 putting in your paving stones go more smoothly and more quickly. Doing these things may even cut down on their labor costs. It will also help keep your home and belongings from being damaged.

    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.

    Before they begin work, be sure to remove any movable items from the area where the paving stone contractor will be working. The more you do the more quickly they can get to work.

    Keep your pets and children away from the area. Your paving stone contractor will be focused on installing your paving stones 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. Some paving stone contractors have large vehicles that require more space than average. Contact your contractor before they begin. 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 paving stones.
