Jim Adkins: Finishing Strong

By James Florence, Diamond Certified Resource Reporter

REDWOOD CITY – While he’s since made a successful career for himself, Jim Adkins’ involvement in the construction industry began with a rude awakening. “I started out as a teenager, working summers for my grandfather, Walter Springs Sr.,” he recalls. “I remember coming to work the first day and thinking I was going to do something easy like drive around in a truck or backhoe. When I walked into my grandfather’s office, he pointed to a brand new shovel in the corner and told me that when I learned how to use that tool, he’d give me the next one. Basically, I started my career making blisters!”

Despite a less-than-idyllic start, Jim went on to become well-versed in all aspects of construction and eventually earned his certification as a master finish carpenter. Today, as president of Springs Construction, Jim says he enjoys building relationships with clients as much as he does building their homes. “I always tell people that my favorite part of the job is handing the keys to the clients and telling them, ‘Here’s your new home!’ The whole process is very rewarding.”

A native of Northern California, Jim lived in various parts of the San Francisco area before finally settling in San Jose, where he lives with his wife, Chris, and their children, Laurel and Bryce. He says his favorite part about living and working in the Bay Area is its natural diversity. “You drive 45 minutes west and you’re at the ocean, and you drive four hours northeast and you’re in the snow. Essentially, you could go surfing and skiing in the same day if you wanted. Not a lot of places can boast that kind of versatility. The more I travel, the more I realize that I have a pretty good place to live.”

While he’s passionate about construction work, Jim’s other love is motorsports. “I watch drag racing and Formula One religiously, and I also follow Motocross and Supercross,” he says. “Whenever there’s a race in town, my son and I are there to see it.”

In both his life and career, Jim attributes his personal success in part to an ongoing process of self-improvement. “I just try to do a little better every day,” he explains. “Whether it’s my performance in the field or my role as a husband and father, my goal is to do things better today than I did them yesterday. I think that attitude has motivated me and helped bring me to where I am today.”

Ask Me Anything!

Q: What’s your favorite sport?
A: I’m a big motorsports fan. In NASCAR, I root for Jeff Gordon; in drag racing, I really like John Force; and in Formula One, my favorite driver is Kimi Räikkönen, who drives for Ferrari.

Q: What was your first concert?
A: Eddie Money at the Cow Palace, when I was 16 years old.

Q: What do you like on your pizza?
A: Pepperoni and extra cheese.

Q: If someone was making a movie about your life, what actor would you choose to play you?
A: Brad Pitt, because I’m extremely handsome! (Laughs)

Q: What Seinfeld character do you identify most with?
A: Kramer. He’s just a happy-go-lucky person—he has his friends and his ideas, and that’s about all he needs.

Q: What’s the best gift you ever received?
A: When I was 12 years old, I wanted a radio-controlled car called a Baja Buggy for Christmas. I was sure my parents got it for me, but Christmas morning came and there was no Baja Buggy. I was disappointed, but I was old enough to understand that my parents probably weren’t able to afford it, so I let it go. Later that afternoon, after some family members had come over, my dad said to me, “Hey, go open the drapes on that sliding door and let in some light.” I pulled back the drapes and there was the Baja Buggy!

Gary Ryan: Entrepreneurial Ambition

By James Florence, Diamond Certified Resource Reporter

SOUTH SAN FRANCISCO — Gary Ryan may be a contractor by profession, but given his diverse occupational background, a better designation might be “jack of all trades,” even though he prefers to think of himself as an entrepreneur. “I worked as a painter during college, and after I graduated, I spent several years in corporate America,” he says. “I’ve worked for a major car manufacturer, been a produce broker, worked for an airline and a shipyard…I’ve kind of done it all. Through everything, however, my main goal was to be an entrepreneur, which I eventually was able to succeed at.”

When it came to fulfilling his entrepreneurial aspirations, it was the construction industry that provided Gary with the opportunity he sought. “During college, I got my contractor’s license for painting, and from that point on, I always had some kind of construction project going on the side, even while I was working in the corporate sector,” he says. “Twelve years ago, my brother, Chad, and I decided to get our general contractor’s licenses and founded Ryan & Ryan Construction. From there, we proceeded to get a few more licenses and have continued to expand our capabilities, so it’s been a gradual progression.”

A lifetime resident of South San Francisco (where he lives with his wife, Iliana, and daughters, Havana and Aviana), Gary expresses his appreciation for life in the City by the Bay. “This is the Disneyland of America,” he laughs. “It’s the best place to live and work. Plus, I’m a third-generation local, so all my friends and family are here.”

Outside of work, Gary keeps himself busy with fitness and family activities. “I’m a health fanatic, so diet and exercise are a big deal for me,” he says. “I keep myself in shape by working out and cycling on a daily basis. I also like spending time with my girls—I usually work six days a week, but Sunday is always family day.”

In regard to his life and career, Gary espouses the importance of maintaining balance. “Too much of anything is too much, so it’s important to find a balance in all aspects of your life,” he affirms. “Sometimes it takes a while to attain it, but eventually there comes a point where you have to say, ‘Enough is enough’ and make some adjustments. I think a big part of it involves being true to yourself as well as others.”

When asked what his future retirement might look like, Gary says he’s not sure because it will probably never happen. “I don’t want to retire. I want to work for the rest of my life. I enjoy what I do, and I love being a boss and mentor. It’s like I said, I’m an entrepreneur to the core.”

Ask Me Anything!

Q: What’s your favorite thing to do on a rainy day?
A: Work. I own another company called ServiceMaster, and our business picks up when it rains, so I’m usually out fixing leaks.

Q: Do you have a favorite TV show?
A: No, but I’m a history fanatic, so I love watching the History Channel.

Q: What’s your favorite local restaurant?
A: Firenze by Night in San Francisco.

Q: Music or talk radio?
A: Music.

Q: What’s your favorite band?
A: Tesla.

Know What You Want
Establish Goals and Requirements for Your Home Addition and House Remodel

Many homeowners find that it is best to know the scope of their project and their overarching goals before talking to a home addition and remodeling contractor in San Mateo County. By knowing what you want to accomplish and the end goal for your project, you’re more likely to be happy with the results of your home remodeling project. So before contacting a local remodeling firm, ask yourself these questions:

  1. Do I want a Diamond Certified company that is rated best in quality and backed by the Diamond Certified Performance Guarantee?
  2. What do I want this remodel or home addition to accomplish? (This could include a room addition for a new baby, building a dining room, updating an older kitchen or turning an unused attic into a new family room.)
  3. Are there any specific requirements or desires I have for the project?
  4. What is my budget for home remodeling?
  5. What characteristics and personal and professional qualities am I looking for from my local remodeling and addition contractor?

What To Ask In Person
Questions to Ask San Mateo County Addition and Remodeling Contractors in Person

Once you’ve narrowed down your choices by interviewing local remodelers over the phone, meet your top choices at your home so they can see the potential jobsite.
You may find it beneficial to take notes on your conversations and recording each addition contractor’s answers, suggestions and general attitude about the project.

  1. How much time will the remodel/home addition take?
  2. When can you start? (Don’t be dismayed by a start date that’s several weeks away. This may be a sign that the contractor is in demand, and will give them time to file for permits and secure appropriate materials. There may be a reason why some contractors are not busy and are therefore available immediately.)
  3. What is your approach to a project of this size? (This will help you know what to expect if you hire this company for your remodel or home addition.)
  4. Will I be able to stay in my home during the remodel/home addition?
  5. Will this home addition or remodel add value to my home?
  6. Do you have any recent projects in my area of San Mateo County where I can see how the house addition and home remodels look from the street?
  7. Will you give me a list of recent customer references I can call?
  8. Do you offer written warranties and guarantees on your work?
  9. How would I handle future service issues? Are you responsible for warranty work if there’s ever a problem with my home addition/remodeling project?
  10. What can I do to make the remodeling and addition process easier?

  • What To Ask References
    Talk with Previous Customers of Local Remodelers and Home Addition Contractors in San Mateo County

    Diamond Certified remodeling and home addition contractors are your best choice, because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a San Mateo County remodeling company, you can have confidence choosing a Diamond Certified remodeling contractor from the greater Bay Area. Diamond Certified reports are available online for all certified addition and remodeling contractors. 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 remodeling company within reach, do some research on your own. Call some references provided by the San Mateo County remodeling companies. Keep in mind, though, that references provided to you by the 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 usually carefully selected names of customers the companies know were satisfied, instead of randomly selected from all their customers. To prevent this, request a list of the company’s 10 most recent customers. Then, use these questions during your phone conversations with previous customers.

    1. Were you satisfied with the home remodel/home addition provided by _(remodeling & addition company name)_?
    2. What was the type and scope of job they did for you (new room addition, kitchen remodel, bathroom remodel, whole home remodeling, sunroom addition, basement remodel, home renovations, etc)
    3. Did the San Mateo County remodeling contractor and home addition company you hired complete the work on time?
    4. Did the contractor keep you up-to-date on the status of the project?
    5. Were there unexpected costs? If so, what were they for and were they avoidable?
    6. If you live in a smaller town such as Colma, Belmont, Foster City, Emerald Hills, Palomar Park, Princeton by the Sea, San Gregorio, Hillsborough or Loma Mar, did the remodeling contractors charge extra to travel to your home?
    7. Did the San Mateo County home remodelers show up on time?
    8. Did they clean up after finishing the home renovations?
    9. If you need home additions or remodeling work in the future, would you use this contractor again?
    10. Would you recommend them to friends or family?
    11. Can I visit your home to see the completed home renovations and room addition?

  • How To Work With
    Get the Most Out of Your Remodel and Home Addition from San Mateo County Contractors

    Before interviewing and choosing a good home remodeling company in San Mateo County, including those serving the larger cities of Daly City, South San Francisco, San Mateo, Redwood City and San Bruno, decide the type of project you’re looking for and the scope of the work you want done. You should also know the budget range you’re looking to stay within. This will help you express yourself to the contractors you talk to, and will give each remodeling contractor and home addition builder the chance to bid on the same project. And it will help you define boundaries so that you don’t end up getting—and paying for—more work than you want or need.

    Planning for the scope of your home addition or renovation will also help you decide whether you want to stay in your home or find temporary lodging while the construction is in process. Home renovations and additions are almost always loud and dusty, and some are more disruptive than others. Consider which rooms you’re having remodeled and the location of the home addition and ask the home remodeling and addition contractors whether they staying in your home during the work. You may want to consider moving to another location if important rooms like the kitchen and bathrooms will be under construction, or if the contractor expects long interruptions in electricity or water.

    Sign a Work Estimate and Contract with a San Mateo County Remodeling Firm
    Once you’ve found the San Mateo County remodeling and addition contractor you prefer, move forward by signing a detailed estimate and contract. The contract should include the remodeling cost, start and end dates and any special requests you’ve agreed upon with your local home renovation contractor. You’ll also want to confirm warrantees and guarantees at this time and put them in writing in the contract.

    Read through the estimate and make sure you understand the terms and limitations before you sign. Contracts are legally binding, so you should never sign a blank or incomplete estimate.

    Ways to Simplify Your Home Remodeling Project or New Home Addition
    Provide adequate storage space if required. Some remodeling contractors in San Mateo County have facilities or travel trailers in which to store remodeling materials and building equipment, but others expect homeowners to provide a clean, dry and accessible storage area for these materials. Ask your home renovation contractor if you’ll need to have space for materials and, if so, how much space is needed.

    Supply clearance and parking space for work trucks. Construction vehicles are often large and may need special parking consideration depending on the size of your driveway or available street parking. Ask your contractor how many work vehicles will need parking space, and whether trailers or other large vehicles will be on site daily. It may also be wise to walk through your property with your San Mateo County remodeling contractor and have them advise you of any clearance issues, lawn ornaments or potential hazards that you can move or minimize before the work begins.

    Prepare your home for construction dust. Remodeling and new addition construction is often a dusty job. Many contractors will provide taping and plastic barriers to prevent dust and construction debris from entering areas of your home that aren’t being remodeled or renovated, but you may be able to save time and money by preparing your home yourself. Talk with your remodeling contractor about steps you can take before the remodeling begins.

    Move and store unnecessary items. Remove furniture, decorations, rugs and other movable objects from the rooms to be remodeled. This will protect them from dust and damage, and will allow your remodeling contractors to move freely and avoid injury. You may also want to temporarily store heirlooms and expensive items that are displayed in high traffic areas of your home. Keep in mind that construction can cause items to shift and fall from shelves and walls, and take down any artwork or decorations.

    Keep children and pets away from the construction area. Your remodeling and home addition contractors shouldn’t have to watch out for kids and pets. So for their safety, keep household pets or children out of the area when your remodeling contractors are working. It’s wise to keep everyone away from the construction area until the construction is completed, as building tools, unfinished construction and exposed wires pose a safety hazard.

Q: Why remodel or add on to my home?
A: Remodeling can modernize your home, improve energy efficiency, and give you a new sense of pride in your home. Many San Mateo County homeowners find that home remodeling projects allow them to upgrade their current home so that they’re happier living in their home and increase the resale value of their home. Like home renovations, home additions can add more usable space to a home. Whether you add a sunroom, a new garage or a bedroom addition, home additions add square footage and usability to your house.

Q: Can I remodel or put on a new home addition myself?
A: Depending on the size of your remodel and your experience with building, you may want to take on some or all of your home renovation project. Home improvement centers carry many of the tools and materials for your home remodeling and addition project, and some homeowners can take on these projects themselves. However, many homeowners find it saves time, money and frustration to hire a competent, experienced remodeling contractor for home renovations. A good remodeling and addition contractor will help you plan, execute and finish the project with much less hassle than you can expect when taking on a project yourself.
Q: How much will my remodeling project/home addition cost?
A: The cost of home renovations depends on the size and scope of your project and the quality of materials used for the addition or remodeling. When getting estimates from local remodeling contractors and home addition builders in San Mateo County, make sure you’re asking the contractors to big on the exact same scope, size and materials in order to get accurate bids.

Q: I have three estimates and they vary greatly in price. Why is this?
A: It’s not uncommon for prices to vary from contractor to contractor. But if the gap between the highest price and the lowest price seems too substantial to be correct, or one bid is much higher or lower than the others, talk with the contractors again. It may be that one contractor didn’t understand the scope or details of the project they were bidding. Ask the remodeling contractors to fully explain their bids, and if they are vague about their answers, move on to the next contractor. Beware of bids that seem artificially low, as some home renovation contractors purposely underbid jobs and then tack on expensive change orders during the construction.

Q: How long do home remodels and additions take?
A: Depending on the size and scope of your project, your remodel may take a few weeks to a few months and room additions can take several months. Problems found during demolition, unforeseen challenges and the skill of your contractor can also add to the timeline. It’s important to get a clear and reasonable timeframe estimate from your San Mateo County remodeling contractor and home addition builder when getting initial cost estimates.

Q: How much value will my addition or renovation add to my home?
A: The amount of value added to your home depends greatly on the renovation you choose and the quality of the workmanship and materials. If you’re planning to live in your home long-term, you may find that your room addition and home renovation will add more to your quality of living in your home, even if it doesn’t add to the resale value of your home. On the other hand, if you’re planning to sell your home soon, you may want to consult with contractors and real estate agents about which home additions and remodeling projects will add the most value to your home.

Q: Do I need to hire an architect, or can my San Mateo County remodeling contractor and addition builder draw my home renovation designs?

A: Depending on the size and scope of your project, there are pros and cons to hiring an architect to draw up home remodeling plans and hiring a remodeling contractor who offers design/build services for home renovations. Here are a few to consider:

  • A general rule of thumb that many builders follow is that if you’re tearing down walls or moving walls, or if your project includes an addition and new construction, hire an architect.
  • Architects are trained to look beyond the outward design and consider the usability of a space, local building codes and zoning regulations, and can draw a complete set of home remodeling and home addition plans.
  • Some design/build remodeling contractors in San Mateo County can offer lower costs and shorter construction timeframes by providing both home designs and building services.
  • Some San Mateo County remodeling contractors prefer to do their own designs in-house and have the ability to draw home remodeling and addition plans in-house.
