James Sardinha: Translating Success

By James Florence, Diamond Certified Program Reporter

PINOLE — After immigrating to the United States from Brazil when he was 11 years old, James Sardinha got started down a path that would lead to a succession of professional opportunities. “My dad was a demolition contractor, and after we came to the U.S., I started helping him by translating and assisting with job bids,” he remembers. “Our operation started small, but pretty soon we’d grown to the point where we were doing whole house and pool demolitions.”

A decade later, James was given a chance to take his career to the next level. “Soon after I arrived in the U.S., I was introduced by a couple of friends to the owner of a local contracting company,” he recalls. “About 10 years later, I reconnected with him and he offered me an opportunity to be part of his company. I saw a great future in the business, and sure enough, I’m still here today.”

Today, as office manager of Silva Contractors Inc., James says he derives satisfaction from seeing the long-term results of the company’s work. “After we tear down an old, dilapidated house and I drive by a year or two later and see a new, well-built house in its place, it’s a good feeling to know I was a part of that process.”

A longtime resident of the East Bay, James divides his time outside of work between family, faith and fun. “I’m a very family-oriented person, and I like to stay surrounded by loved ones,” he affirms. “Also, religion is a big part of my life; I go to church at least twice a week.” On weekends, James can typically be found at the movies with his fiancé, Jordana, or exploring an unfamiliar region of the Golden State. “I enjoy going to new places, and there’s a lot to see and discover in California.”

In his life and career, James has learned the value of patient perseverance. “I believe everything has a specific timing, so you just need to wait and be in the right place at the right time when things happen,” he says. “I also believe what goes around comes around, which is why I try to do my best every day in hopes that it will come back to me.”

When asked the first thing he’d do if he could retire tomorrow, James says he’d take his love of travel beyond the West Coast. “I’d like to see more of the U.S. I haven’t been to the East Coast, so it’d be neat to visit places like New York, which I’ve only seen in movies. I’d also like to visit some foreign countries and get to know more of the world and its many cultures.”

Andrew Headington: A Twofold Fulfillment

By James Florence, Diamond Certified Resource Reporter

UNION CITY — As a lover of the arts and the outdoors, Andrew Headington feels fortunate to have found a job that fulfills his dual passions. “I’ve always had a passion for the arts, but at the same time, I’ve always been a very outdoorsy person, so when I heard about landscape architecture in college, it seemed like a good fit for me,” he explains. “I ended up getting my B.S. in landscape architecture from the University of Connecticut, and I’ve been in the field ever since.”

Today, as sales manager for System Pavers, Andrew says his favorite part of his job is the daily challenges it entails. “I love meeting new people and helping them solve their landscape and hardscape problems. Every day is a new challenge, which keeps things exciting.”

A resident of Marin (where he lives with his wife, Laurie), Andrew expresses his appreciation for the Bay Area’s temperate climate and lush landscape. “I have no complaints about the weather in Marin. It’s absolutely gorgeous up here. The best part is you can take part in outdoor activities basically year-round.”

Outside of work, Andrew can often be found pursuing one of his three main hobbies. “First off, I brew my own beer, which I’ve been doing for about 15 years,” he explains. “Secondly, I play guitar in a local band called Polkalicious that gigs around San Francisco and the Greater Bay Area. Basically, we take hits from the ’80s, ’90s, and today and turn them into polka songs. Thirdly, I’m an avid kiteboarder. Kiteboarding is like surfing, but you have a giant kite attached to your surfboard and use the wind to navigate your way around.” In addition to these pastimes, Andrew enjoys working on his house, hiking and snowboarding.

In regard to his professional career, Andrew espouses the importance of honesty. “It may sound a bit generic, but the phrase, ‘Honesty is the best policy’ is absolutely true, especially from a sales standpoint,” he says. “That’s why I always make it a point to be honest with customers, and I do my best to subvert the ‘used car salesman’ stereotype. I also try to be a good leader and have a positive impact on my coworkers.”

When asked the first thing he’d do if he were to retire tomorrow, Andrew says he would see the world. “I would definitely travel. In particular, I’d like to visit Southeast Asia. There’s some incredible development happening over there, with some really interesting designs and just a totally different way of life, so it’d be neat to experience that.”

Ask Me Anything!

Q: What’s your favorite snack?
A: Bananas.

Q: What’s your favorite local restaurant?
A: Sol Food in San Rafael.

Q: If you could time travel, would you go to the past or the future?
A: I’d go to the past to uncover some of the mysteries of ancient times. For example, I would love to go back and see how the Egyptians built the pyramids.

Q: What’s your favorite Bay Area brewery?
A: Russian River Brewing Company in Santa Rosa.

Q: If you could immediately master any musical instrument, what would you choose?
A: The banjo that’s hanging on my wall. Maybe I’d start a bluegrass band in addition to my polka band.

Renato do Carmo: Piecing it All Together

By James Florence, Diamond Certified Resource Reporter

RICHMOND — For Renato do Carmo, progressing from trainee to expert in the paver industry was simply a matter of piecing it all together. “I got into the paver industry through friends,” he recounts. “I started as a helper and gradually learned the trade until I became an installer. After working for a couple of companies, I began working as a subcontractor as part of a partnership I formed with some other industry professionals. When the partnership ended in 2017, I decided to take the years of experience I’d accumulated and start my own paver installation company.”

Today, as owner of D’Carmo Interlocking Pavers, Inc., Renato says his favorite part of his job is bringing his clients’ dreams to life. “I enjoy taking a customer’s vision for their project and turning it into reality. There’s nothing like delivering the final product to the customer and seeing the smile on their face. It makes me feel very proud.”

Originally from Brazil, Renato came to the United States in 2009 and resides today in Richmond. Outside of work, he spends the bulk of his free time relaxing. “I work a lot, so when I’m off, I like to relax at home. My main hobby is playing video games—it’s a great way to unwind and detach from the stresses of work. Occasionally, I like to go out with friends, but I’m really more of a homebody.” Renato also takes semi-regular trips to Brazil to visit family and friends.

In regard to his professional career, Renato espouses the value of having a strong, unified team. “I don’t see this business as me, the owner, and my employees—I see it as a team,” he affirms. “When you work as a team, everyone is on the same page and working toward a common goal, which results in a great outcome. That’s why I do my best to keep my employees happy and maintain a consistent staff. After all, if we have a good thing, why should we change it?”

Ask Me Anything!

Q: What’s your all-time favorite video game?

A: “God of War.”

Q: What’s your favorite thing to eat for dessert?

A: Ice cream.

Q: What’s your favorite movie?

A: The one that stands out for me is “Ghost” with Patrick Swayze. I saw it when I was young and it marked a point where I really started to appreciate movies.

Q: Do you collect anything?

A: I collect action figures of video game characters.

Q: Are you an early bird or a night owl?

A: A night owl.

  • What To Ask References
    Questions for References of Good Paving Stone Installers in Alameda County

    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 Alameda 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.

    • Were you satisfied with the service from this local paving stone contractor?
    • What type of paving stones were used for your job? (Concrete pavers, natural pavers, non-pourous pavers, interlocking pavers, etc.)
    • Did the paving stone company finish the work on schedule?
    • Did they show up for work on time?
    • Would you recommend this paving stone 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 area such as Russell City, San Lorenzo and Sunol, did the paving stone contractors charge you extra to cover travel expenses?

  • How To Work With
    How to Get an Accurate Estimate for Paving Stones From an Alameda County

    Paving stones do not have to be a major financial setback. Plan your budget and stick to it. After you have found an Alameda County paving stone company in Alameda 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 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.

    Committing To an Alameda County Paving Stone Contractor You Trust
    When you feel satisfied with the information you have received from your Alameda County paving stone contractor, sign the contract. Be sure that they have a phone number where you can be reached at all times.

    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.

    Preparing Your House and Yard for Installing Your New Pavers
    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 and can keep your home and belongings from being damaged.

    Remove any furniture or movable items from the area where the paving stone 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.

    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 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 paving stones.

    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.

Q: Are pavers appropriate for using on a driveway?
A: Yes! Paving stones are great for driveways. You need to choose an appropriate base material for the paving stones. This base must be compacted.

Q: Is it possible to use paving stones over my already existing concrete?
A: While it is possible to install paving stones over concrete, you may need a material on top of the concrete before laying the paving stones. You might want to have the concrete removed. Many times it is not that expensive.

Q: Do concrete pavers need to be sealed?
A: While sealing is not necessary, there are sealers available. These sealers do make stains easier to remove. This sealer is applied after the pavers have been cleaned. It soaks into the pavers and sand joints.

Q: What keeps pavers from cracking like concrete?
A: Paving stones have a much higher density than concrete. Also the interlocking of paving stones enables it to bear a greater load. Since there are joints, these joints relieve pressure allowing movement for the paving stones.

Q: How long will my new paving stones last?
A: Many paving stone manufacturers offer a lifetime warranty. Because they are so easy to repair or replace, there is no reason to worry.

Q: How do I go about enhancing the color of my paving stones?
A: You can apply a paver enhancer to your paving stones. This will give the pavers a “wet look” and it also brings out the color.

Q: Why is sand installed between the base and the paving stones?
A: The sand will allow the final grade to be more precise. This sand will also keep the pavers from developing efflorescence (which is the white powder that is often seen on paving stones). The sand will also help with any drainage and allow the water to go into the base and then into the ground. The sand also acts as a cushion for the stones and helps keep them even as they settle.

Q: How do I choose the right paving stones for my project?
A:Because of the overwhelming choices in paving stones, this can be difficult. Not only is there a wide array of choices but you also need to know other factors (such as drainage) that will influence our decision. First, visit several paving stone companies and look at the displays. Find the stones that most appeal to you. Then, talk to the contractor and let them know which displays attract you. The contractor is qualified to guide you through the process of selecting materials. For instance, if the display that most appealed to you isn’t appropriate for your project, they can find a material that is appropriate but looks similar to what appealed to you. Let the contractor guide you through the process.

Q: What are interlocking paving stones?
A:Interlocking paving stones interlock to allow each to move independently. This allows the pavers to carry a bigger load because the weight is spread out. This is also the key to the interlocking paving stones strength.

Q: How do I go about removing stains?
A:Replacing stained pavers is the easiest or some can be flipped over. However, there are special cleaners made that will remove stains or do surface cleaning.
