Stephen Wood: Open Range

By James Florence, Diamond Certified Program Reporter

MENLO PARK — Following college graduation, Stephen Wood had found himself in an occupational cul de sac, working as the assistant manager of a coffee shop. Thanks to a long-time acquaintance, however, he was given an opportunity that opened the door to a lifelong career. “In high school, I dated a young lady and got to be pretty good friends with her father, who was one of the first commercial landscape contractors in the Bay Area,” he recalls. “He and I had stayed in touch over the years, and one day he made me an offer to come work for him, which was by far a better opportunity than anything else I had going.”

Stephen spent the next twelve years gaining experience as a landscaping professional, before striking out on his own in 1989. Today, as owner of EW Landscape, he says his favorite part of his job is devising ways to make his customers’ landscapes more water-wise. “From the mechanics of moving water to modern innovations in devices and techniques, I find irrigation fascinating. Plus, as we head into the fourth year of the current drought in California, it’s become a major environmental concern, so I get a lot of satisfaction from improving irrigation efficiency on my customers’ properties.”

A resident of Menlo Park (where he lives with his wife, Lois), Stephen considers the Bay Area an ideal place to be in the landscaping business. “In the Bay Area, you might say landscaping is a ‘24/7’ job, because you can plant nearly any time of the year,” he says. “For us, business is ongoing, whereas, in other parts of the country, landscapers are out of work three or four months out of the year due to winter conditions.”

Outside of work, Steve likes to spend the bulk of his time outdoors, exploring the natural beauty of Northern California. “I really enjoy the outdoors, and California is one of those places where you can access a lot of amazing areas within a relatively short distance,” he says. “I’m into hiking and camping, as well as water rafting and ocean kayaking. One thing that’s still on my bucket list is to go rafting through the Grand Canyon.” Stephen also likes to spend time with his grown son, Tyler, who works in the tech industry.

In regard to his professional career, Stephen believes it’s important to go above and beyond to ensure accuracy. “When it comes to estimates, I’ve seen what a lot of my competitors do, which consists largely of guesswork. In contrast, my estimates are usually six to seven pages long, detailing each and every line item for each category of work we’re doing. In addition to ensuring accurate pricing, I think this adds to our customers’ confidence in us.”

When asked the first thing he’d do if he could retire tomorrow, Stephen says he’d migrate to a new setting. “There are places outside of California where it doesn’t cost an arm and a leg just to make the bills, which would be nice for a change. I’d love to live somewhere like New Mexico or Montana, and do what I’ve dreamed about since I was five years old: be a cowboy.”

Ask Me Anything!

Q: Do you consider yourself a dog person or a cat person?
A: Dog person.

Q: What is your favorite season of the year and why?
A: Fall, for the colors.

Q: If you could travel to any country in the world, where would you go and why?
A: I’d like to go back to England. My family lived in London for about a year when I was young, and the English struck me as a people with a very rich, detailed history.

Q: What was your favorite toy as a child?
A: A rope.

Q: What’s your favorite holiday?
A: Thanksgiving—none of the gift giving, but all of the family.

Know What You Want
What To Ask Yourself Before Starting Your Search For A Landscape Maintenance Professional In San Mateo County

You’ll have to consider a few things before beginning your search for a trustworthy landscape maintenance company in San Mateo County. First and foremost, you’ll need to decide exactly what level of landscaping maintenance is necessary for your outdoor space. You’ll need to spend a considerable amount of time in your yard to establish what exactly needs to be accomplished on a weekly, monthly and seasonal basis.

You’ll want to try very hard to be honest with yourself about your specific needs at this point. You will want to send your landscaping maintenance proposal to at least three companies for a bid prior to deciding on a professional to go with, and you’ll want to be sure that they are bidding on the same job or the cost estimates will not be accurately comparable.

You are welcome to use the following questions as a guide as you consider taking the very important first step toward hiring a San Mateo County landscaping maintenance professional. You won’t be sorry that you took the time to evaluate your needs before attempting to hire help in the area of landscaping maintenance.

  • Do I want a Diamond Certified landscaping maintenance company that is rated best in quality and backed by the Diamond Certified Guarantee?
  • How long do I want to employ someone to maintain my landscape? What will my contract time frame be?
  • What exactly do I want to be done on a seasonal basis (i.e. spring clean-up and fall leaf removal)?
  • Do I have areas that need to be re-mulched on a regular basis?
  • Are their trees and shrubs that need trimming and/or pruning? How often would this need to be done?
  • How often do I want my lawn to be mowed? How often should it be mowed?
  • How concerned am I that my lawn look manicured? Is it important to me that a landscaping maintenance company creates a design for my clipped lawn?
  • Am I interested in a fertilization plan for my lawn and/or gardens?
  • Are there any areas of my outdoor space I am particularly concerned about? What are they and what are my specific concerns?
  • Should I make a plan for seasonal color in my flower beds?

You’ll be busy interviewing several San Mateo County landscaping maintenance professionals over the phone, but when you’re finished with that it is imperative that you narrow your choices to a select few in your surrounding area. You’ll want to visit these companies in person to get a feel for their operation and ask them further follow-up questions to make your final decision about which landscape maintenance company will fit with your needs and schedule.

  • What To Ask References
    Questions For References Of Landscape Maintenance Companies in San Mateo County

    Feeling complete confidence in your choice of a San Mateo County landscaping maintenance company without checking the references of past clients can be difficult. But do you have time to do all that research? Do you trust that the references you’ve been given are reliable? In both cases, probably not.

    You’ll want to choose a Diamond Certified landscaping maintenance company because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a landscape maintenance company in San Mateo County, 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.

    Sometimes you can’t find a Diamond Certified landscaping maintenance company in your area (most likely if you are in the smaller towns of Belmont, Loma Mar, Palomar Park, San Gregorio and Sharp Park), and then you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your landscaper. Keep in mind, though, that references provided to you by the landscaping maintenance company 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.

    Use the questions below when doing your own research, and 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. Is your outdoor space currently being maintained by this company? If no, why not?
    2. Did this company provide open and timely communication throughout your maintenance plan?
    3. Did this company make sure to leave your outdoor space safe for your family and pets during and after landscaping service?
    4. Were grass clippings, leaves and other debris collected as scheduled?
    5. Have you received any specialized services from this company? If yes, what were they and were you happy with the outcome?
    6. Were there any charges added that surprised you? Were you happy with the estimate to actual cost difference?
    7. Did this company keep current with all local water ordinances?
    8. Does this company understand irrigation systems (if you have one) and were they willing to educate you on how to keep your yard properly watered between their service calls?
    9. Are you happy with response time to calls about specific and timely landscaping maintenance issues and requests?
    10. Are you satisfied with their service?
    11. Would you/have you recommended this contractor?
    12. Would you hire this landscaping maintenance company again?

  • How To Work With
    The Bidding Process: An Important Step in Hiring a San Mateo Landscaping Maintenance Service

    While you may think you’ve narrowed your selections down enough during the interviewing process, the truth is, you can’t completely make your decision until you’ve had a least three bid on your landscaping maintenance specifications. Think of the interview process as round one and the bidding process as the final round in hiring a responsible and effective San Mateo County landscaping maintenance professional.

    It is time to begin the bidding process. Utilizing the answers to the questions above from each company, determine at least three that you would like to work with further.

    Remember, professionals recommend that you have your bids for the following year of service to landscaping maintenance companies no later than October 31 of the previous year. Landscaping maintenance business picks up in early spring, and you’ll want to make sure you’ve secured a good landscaping maintenance professional well in advance.

    Once you have decided on three to five companies to send your bids to, send them identical specifications and an expected date of return for their bids.

    During the bidding process, keep the thoughts below in mind:

    • Did one company provide recommendations based on your specifications that you could not have known about when you put your plan together? Did they include these in your bid?
    • Did any of the companies make suggestions on how to tailor your landscape to decrease the amount of maintenance you need?
    • Did any of the companies offer to present their bid to you at the property to be maintained so that they could see the outdoor space and answer any specific follow-up questions at the time of the presentation?

    The landscaping maintenance plan you present to the different companies is a guide they should use to develop a more comprehensive plan and bid. The landscaping maintenance company you should ultimately decide to hire should take your specifications and then use their knowledge and expertise to craft a more streamlined and detailed plan for your landscape maintenance needs.

    It should become clearer which landscape maintenance service you should hire because they will be the ones offering you suggestions on how to create a landscaping maintenance plan that more fully fits your needs and enhances their ability to serve you.

    Understanding the Elements of the Bid and Estimate from Your San Mateo County Landscape Maintenance Company
    You should know that the initial bid you receive from a landscape maintenance company looks quite similar to the final estimate you get from the company you decide to hire. Unless you’ve overlooked a large section of landscaping maintenance in your outdoor space, the bidding process should lead smoothly to an estimate you can trust and a contract you feel comfortable signing.

    Your bid and estimate should include:

    • Charges for a monthly plan that includes repairs, maintenance, fertilization, replacement of organic materials, etc.
    • Amount of days per month that your landscape will be maintained
    • A detailed schedule of when service calls will be made and what exactly will be included during each service session

    Both the bid and estimate should be as detailed as possible. If you are uncomfortable or unclear with anything outlined in the bid and/or estimate, you should certainly speak at length with your representative from the landscaping maintenance company about your concerns and get them resolved before making your final hiring decision or signing a contract with your chosen company.

    What to Expect When Working with Your Landscaping Maintenance Company
    It is time to take a sigh of relief. The hard part is over. Now you can sit back, relax and enjoy the fruits of your laborious search for your San Mateo County landscaping maintenance company, but you may want to gain a basic understanding of what landscaping maintenance plans include, however, to make sure that your maintenance plan is going to cover all your areas of need as well as to ensure that the company is doing all they promised in their bid and estimate.

    Be aware that most landscape maintenance companies think of actual landscaping as a different service than dealing with your irrigation system, if you have one. The basic elements of each service are detailed below.

    Typical landscaping maintenance plans should include:

    • Appropriate pruning and trimming
    • Proper maintenance of organic materials including fertilization and winterization
    • Aerating, fertilization and proper mowing of grassy areas
    • Mulch renewal
    • Proper use of disease and pest control
    • Installation of seasonal color in flower beds

    • Maintaining all components of the system including filter flushes
    • Development of a watering schedule that fits your landscapes needs and complies with local water ordinances
    • Setting the system to the developed schedule and checking its proper functioning at least once per season
    • Educating you on ways to be aware that your system is functioning properly

Q: What exactly are landscape maintenance services?
A: Landscape maintenance is whatever measures are taken to keep an outdoor space clean, neat, enjoyable and attractive. A landscaping maintenance professional can perform a variety of tasks to accomplish this including mowing, edging, removing organic debris (i.e. grass clippings, weeds, leaves, etc.), pruning, trimming, seasonal planting, fertilization, pest control, management of irrigation systems, etc.

Q: Do I need a professional landscaping maintenance plan?
A: Simply put, yes. Many people are too busy to give their yards and properties the care and attention necessary to maintain curb appeal and complete enjoyment of their outdoor space. A good landscaping maintenance program can reduce your stress, add to the value of your property and increase your satisfaction with your outdoor space.

Q: What does a good landscape maintenance program usually cost?
A: This is a tricky question to give a broad answer to. Most companies determine the cost of each landscaping maintenance session by measuring your property including grass to be mowed, beds to be planted, pruning/trimming to be done and then factor in all the other services you request. The best way to know you are getting what you want for your money is to develop a detailed plan before approaching three to five landscaping maintenance companies for a bid and deciding from there.

Q: Should I sign a contract with my landscaping maintenance company?
A: Of course. Your professional relationship with a landscaping maintenance company should be one of trust and longevity. By signing a contract, you will have complete understanding of what maintenance will be performed on your property and when it will be performed. If you like how a company handles your landscaping maintenance plan and want to continue using their services, you should look to renew your contract at least once a year.

Q: How often should I have my lawn mowed?
A: The frequency of grass clipping and lawn height are both determined by what kind of grass you have and the amount the grass grows in the climate you are in. A good estimate is every four to seven days, depending on growth rate.

Q: Do I need to have mulch spread on my flower beds?
A: It is up to you, but most landscaping maintenance professional agree that the benefits of mulch far outweigh the cost of upkeep. Mulch brings a uniform beauty to your property while reducing weeds and retaining moisture. It provides natural insulation against extreme temperatures and enriches your soil, further cutting down on your need for fertilization.

Q: What if it is raining on the day my landscape maintenance crew is supposed to service my property?
A: Most landscaping maintenance companies have a plan for weather contingencies. You should find out what that plan is before selecting one. Most often companies try to determine if they can still work through the weather without causing more harm than good. If not, they’ll reschedule for the following day.

Q: What is aeration and should I consider it for my lawn?
A: Aeration is a process that creates holes through your grass, turf and soil and deposits the plugs on top of your lawn for eventual decomposition. While not every lawn needs aeration, it is a good issue to discuss with your landscaping maintenance professional because over time, the process of aeration decompacts soil and allows for better growing conditions and irrigation.
