Thomas Daly: Building a Livelihood

By James Florence, Senior Writer

MILL VALLEY — Daunted by the prospect of a career spent behind a desk, Thomas Daly left his home country to build a new livelihood in the United States. “I was working an office job back in Ireland and I hated it,” he remembers. “Prior to that, I’d spent some time in the U.S. playing for a Gaelic football team, so I decided to return to New York, where I got a job building high-rises. After a few years, I went to Alaska to work on the oil pipeline, and from there I went to Australia to work on another. Eventually, I returned to the U.S., where I settled in Marin County, got my contractor’s license and have been working for myself ever since.”
Today, as owner of Thomas A Daly Construction, Thomas says he enjoys his job’s combination of physical work and mental challenges. “I love that I get to be outside working with my hands every day. Plus, I like that fact that I’m always learning new things. As a contractor, you never stop learning because every job requires a different set of solutions.”
A resident of Mill Valley, Thomas likes to spend his free time staying active. “I’m a member of Bay Club Marin in Corte Madera, where I spend a lot of my time swimming and working out,” he says. “I also play a bit of tennis and squash on the weekends, and occasionally indoor soccer, though I’m getting a bit old for that.” Thomas also likes to travel on a regular basis. “I have family and a small farm in Ireland, so I like to go back there a few times a year. My wife usually books us a trip to somewhere like Spain or Portugal while we’re there. I enjoy going to different places and meeting different people.”
In regard to a professional philosophy, Thomas believes in providing the same level of quality and service he’d expect for himself. “I try to perform every job as if I was working on my own house,” he explains. “When doing estimates, I always recommend what I think is best for the customer’s particular circumstances. Overall, I believe in giving my customers quality work for a fair price.”
When asked the first thing he’d do if he were to retire tomorrow, Thomas says he wouldn’t. “I would close the lid on my own coffin,” he laughs. “Retirement isn’t on my horizon—I’ll keep working until I drop. I enjoy my time off, of course, but I like having work to come back to, and that will be the case as long as I’m in the world.”
Ask Me Anything!
Q: Are you an early bird or a night owl?
A: Both. I go to bed around midnight and I’m usually up by 6am.

Q: Coffee or tea?
A: When I’m the U.S., I drink coffee, but when I’m in Ireland, I drink tea, which is what I was raised on.

Q: What’s your favorite local restaurant?
A: I have two: The Cantina in Mill Valley and The Mayflower Pub in San Rafael.

Q: What kinds of books do you like to read?
A: Mostly biographies and history books, especially anything about the American Revolution and the Civil War.

Q: If you could talk to anyone living or dead, who would you choose?
A: Abraham Lincoln. I’d like to hear what he has to say about what’s going on in this country today.

  • What To Ask References
    Interview Questions You'll Want To Ask Previous Customers of Marin County Patio and Deck Builders

    It's best to choose a Diamond Certified deck and patio contractor because all certified companies have passed an in-depth ratings process that most other companies can't pass.

    If you can't find a Diamond Certified deck and patio 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 deck and patio contractor.

    Keep in mind, though, that references provided to you by the deck and patio 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 hand-picked instead of randomly selected from all their customers.

    If you do call references on your own, ask specifically 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 you'll want to ask include these:

    • Were you satisfied with the services from this deck and patio contractor?
    • If you live in a smaller area such as Muir Beach, Muir Woods, Nicasio, Olema and Point Reyes Station, were you charged extra for the deck and patio contractor's travel?
    • Did they communicate well with you and keep you updated on the status of your deck and patio project?
    • Did the deck and patio contractor show up on time?
    • What type of deck did they do for you?
    • Did you feel the deck and patio contractor cleaned up satisfactorily after they completed your job?

  • How To Work With
    Receiving an Accurate Estimate From Marin County Deck Contractors

    Building a new deck or patio doesn't need to be a major financial setback. Plan your budget and stick to it. After you have found a Marin County deck and patio contractor that you can trust, you will have peace of mind having your deck or patio built.

    First, meet with the contractor and outline what your specific plan is for your deck or patio. 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 rush into the project. 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 concerns you have.

    Be sure to get all estimates in writing before any of the deck work begins. The estimate should include an itemized list of the cost of the building supplies and the labor. Don't ever sign a blank estimate.

    Request a Contract for Your New Deck or Patio
    When you feel satisfied with the information you have received from your Marin County deck and patio contractor, sign the contract. Make sure that they have a phone number where you can be reached at all times.

    The contractor should stay within the estimate. However, if the actual building costs exceed the original amount of the estimate, the deck and patio contractor must get your approval before moving ahead.

    Getting Your Home Ready for Your New Patio or Deck
    Professional deck and patio 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 building your deck and patio go more smoothly. 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 deck and patio area. Before they begin work on your deck and patio, remove anything that may be in the way such as barbecues or lawn chairs. The more you do the more quickly they can get to work.

    Provide parking space and room for their work vehicles to maneuver. Some deck and patio 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 building of your deck and patio begins.

    Trim plants and bushes that are in the way of your new deck and patio 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.

    Keep your pets and children away from the area. Your deck and patio contractor will be focused on building your deck and patio 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.

    • Ask your deck and patio contractor if you should call to check on the progress or if he will call you with updates.
    • Be sure your service representative has a phone number where they can reach you at all times while they’re building your deck and patio. The work will move along more smoothly if your deck and patio contractor can reach you for any necessary updates, questions or work authorizations.

Check The Work
Compare the Contract With the Completed Deck and Patio

When your deck or patio is complete, most patio contractors will give you a written invoice that details the completed work.

Your invoice should include:

  • The deck builder's name, physical address and license number.
  • A list of all services performed.
  • An itemized list of all the building supplies purchased.
  • The total cost for supplies, including the amount due for labor.
  • Any applicable warrantees or guarantees provided by manufacturers or the company.

If you have any questions about the work or materials used to build the deck or patio, now is the time to ask.

Top 10 Requests
Top Deck and Patio Requests for Patio and Deck Builders in Marin County

Is it time to replace your deck or patio or to add to your home by building a deck? You will want to know which type of deck is right for you. Deck and patio contractors in Marin County offer a variety of materials for building your deck or patio. Some are more popular than others and the maintenance requirement also varies. The following are the most familiar requests.

Eco-Friendly Vinyl and Composite Patio and Deck Materials
Many homeowners are interested in building decks with green materials. There is a variety of materials that meets the standards of these homeowners. Probably the most eco-friendly material for decks is wood, but there are also many composites that are made up of a high percentage of recycled materials. Vinyl is also available that meets this criteria.

Solid Composite Wood Decks and Patios
Composite wood gives you the look of natural wood, however the maintenance is much easier. A composite wood deck is made of a blend of wood fiber with plastic. This type of wood comes in different colors and it is very durable. Solid composite wood decks expand and contract as the weather fluctuates. The plastic gives this deck more durability.

Pressure Treated Lumber
Many consider this a very affordable option. It does require some maintenance and although it is pressure treated, it needs to be taken care of. With regular maintenance, this decking will last and look great.

Cedar and Redwood
These woods are very popular because they are naturally beautiful. They do require regular maintenance and, unfortunately, they are liable to damage from insects and the weather. With proper maintenance such as staining and sealing, this decking can last for many years.

Natural Wood Decks and Patios in Marin County
This is probably the most popular material for building a deck. It is naturally beautiful and also quite affordable. While it is cheaper than composite material, the maintenance requirements for wood are greater than for composite. Another reason homeowners choose wood is that it is more versatile and can be stained a different color.

Hollow Composite Wood
Hollow composite wood does not have quite the natural look of wood as the solid composite. You will also find that it is less durable; however, hollow composite wood costs less than solid composite wood. Hollow composite wood decking is stiffer than solid composite wood and allows you to run wires for lighting or speakers.

Vinyl Decking Material
Vinyl is a durable option for decks. It is lower in maintenance than wood but does give more of a contemporary look. Its appearance is more man-made. One of its greatest benefits is that it does not warp or rot and it is not subject to mold. Most vinyl decking comes with a lifetime warranty.

Tropical Lumber
Tropical lumber or exotic imports are considered heavy hardwoods. This can include mahogany or ipe. This lumber is resistant to insects and damage from weather.

Aluminum
Aluminum decking is very low in maintenance however it is not inexpensive. It is recyclable. One of its positive aspects is that it is almost indestructable and even fireproof. Aluminum may cost several times more than exotic lumber. Homeowners choose it because it is so easy to take care of.

Untreated Softwood
Untreated softwood is inexpensive. Softwoods include pine and fir. Although it is inexpensive, it will be necessary to treat it every two years or so with stain, paint or sealant. A problem with untreated softwood is that it is susceptible termites.

Frequently Asked Questions
Frequently Asked Questions for Good Deck and Patio Contractors

Q: Why choose a Diamond Certified deck and patio contractor?
A: Diamond Certified helps you choose a deck and patio contractor with confidence by offering a list of top-rated local companies who have passed the country's most in-depth rating process. Only deck and patio contractors rated Highest in Quality earn the prestigious Diamond Certified award.

Most companies can't pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoingresearch and ratings. And your purchase is backed by theDiamond Certified Performance Guarantee. So you'll feel confident choosing a Diamond Certified deck and patio contractor.

Q: How much does an average deck or patio cost?
A: Every deck and patio is unique. There are many variables which are factored into the price of your project. The price will depend on the materials you choose, the railing systems, and if any plants or trees need to be removed. All of these are figured into the price of your project.

Q: What decks are maintenance free?
A: Most people consider composite decks fairly maintenance free. They do not need to be stained or painted. If these composite decks are cleaned and taken care of, they will last for many years and look very similar to when they were first installed. Other benefits from composite decks are that there are no slivers to get into bare feet and it is less slippery when wet.

Q: Do I need a permit to build a deck?
A: In most cities a permit is required because a deck is considered structural. This means it carries weight other than itself – the weight of a person. Because of the way some decks are built – high off of the ground – they require structural building to transfer the weight of the load to the ground.

Q: What happens if I build without a permit?
A: We highly recommend that you do not do it. Getting a permit isn't that difficult and it will save you the hassle of any difficulties that arise from not having a permit. Without a permit, you could be fined or not able to sell your house until the permits are obtained.

Q: Is it necessary to maintain my wood deck?
A: If you want your deck to look good and keep it from rotting or splitting, then, yes, you need to maintain your wood deck. Regular maintenance will keep your deck from showing signs of deterioration from the water or sun. In time, without maintenance it will eventually rot or the wood will split.

Q: When should I seal my wood deck?

  • After your wood deck is completed, wait six to eight weeks to seal it. Sealing your wood deck will keep it from discoloring and it will also keep the wood from splintering.
  • All wood decks need to be cleaned. Power washers do not damage wood when they are used properly. However, power washing decks and patios may raise the grain of the wood. Before you seal your deck, you will need to sand this down.
  • Seals are a protection for wood that works by penetrating the wood fibers. This slows the water absorption causing the water to evaporate before it is absorbed.
  • Many types of sealant are an oil-based covering that protects wood. It not only protects but improves the appearance of decks and patios. Deck sealing lasts for several years depending on weather conditions.
