Know What You Want
What To Ask Yourself Before Beginning Your Search For A Contra Costa County Landscape Maintenance Professional

You'll need to consider a few things before starting your search for a trustworthy landscape maintenance company in Contra Costa 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.

It is essential 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.

Use the following questions as a guide as you consider taking the very important first step toward hiring a Contra Costa 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?

  • What To Ask References
    Questions For References Of Contra Costa County Landscaping Maintenance Companies

    You can't have complete confidence in your choice of a Contra Costa County landscaping maintenance company without checking the references of past clients. 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.

    That's why it's best 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 Contra Costa 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.

    If you can't locate a Diamond Certified landscaping maintenance company in your area (most likely if you are in the smaller towns of Bay Point, Clayton, Kensington, Port Costa and Walnut Heights), 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.

    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?
    7. Were you happy with the estimate to actual cost difference?
    8. Did this company keep current with all local water ordinances?
    9. 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?
    10. Are you happy with response time to calls about specific and timely landscaping maintenance issues and requests?
    11. Are you satisfied with their service? Would you/have you recommended this contractor?
    12. Would you hire this landscaping maintenance company again?

  • How To Work With
    The Bidding Process: An Essential Step in Hiring Your Contra Costa County Landscaping Maintenance Company

    You can't completely narrow your decision to one landscaping maintenance company 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 Contra Costa County landscaping maintenance professional.

    When you've come up with a specific landscaping maintenance plan, 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 following thoughts 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 will be clear which company 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.

    Fundamentals of the Bid and Estimate
    The initial bid you receive from a landscape maintenance company, whether you live in the bigger cities of Concord, Antioch, Pittsburg, Danville and Martinez or the littler towns of Alamo, Briones, Maltby, Orinda and Vine Hill, should look 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: the charges for a monthly plan that includes repairs, maintenance, fertilization, replacement of organic materials, etc.; the 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.

    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.

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.
