Know What You Want
Knowing What You Want From a Deck Cleaning and Restoration Company in San Mateo County

After you have done some initial research and know what you are looking for, talk with a few local deck cleaning and restoration companies. Have a written list of questions and write down each contractor’s answers. Good deck cleaning and restoration companies will not provide estimates until they have first seen the job. Don’t get an estimate from every company you interview. If a company can’t answer your questions or they don’t meet your expectations, move on to the next company. Choose the best companies and ones that you are truly interested in to give you estimates.

It is up to you to determine what results you are expecting from your deck cleaning and restoration. Figure out your timeline and any changes you want to make including the color of your deck. Here are questions that you may want to ask:

  • Do I want a Diamond Certified company that is rated best in quality and backed by the Diamond Certified Guarantee?
  • What personal and professional characteristics would I like my San Mateo County deck and patio contractor to have such as good communication skills, timeliness, honesty, integrity, and reliability?
  • Am I interested in changing the color or style of my deck?
  • What is my timeline?
  • Am I planning on living in this house over the long-term or am I going to use it as rental property?

  • What To Ask References
    Interview Questions to Ask Previous Customers of Local Deck Cleaning and Restoration Companies in San Mateo County

    It’s best to choose a Diamond Certified deck cleaning and restoration company in San Mateo County because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a deck cleaning and restoration company in San Mateo 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. 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 deck cleaning and restoration company 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 cleaning and restoration company. Keep in mind, though, that references provided to you by the deck cleaning and restoration 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 hand-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 deck cleaning and restoration company?
    • Did they keep communication with you up to date on the status of your project?
    • If you live in a smaller town such as La Honda, Loma Mar, Millbrae, Montara and Moss Beach, did you have to pay extra for their travel expenses to your home?
    • What type of work did you have done – clean, restore or both?
    • Did they finish the work on time?
    • Did they show up for work on time?
    • Would you recommend this deck cleaning and restoration company 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?

  • How To Work With
    Meeting With the Contractor to Sign a Deck Cleaning and Restoration Contract

    To keep your deck cleaning and restoration from becoming a major financial setback, set your budget and stick to it. You can have peace of mind having your deck cleaned and restored after you have found a San Mateo County deck cleaning and restoration company in San Mateo County that you can trust.

    Use the notes that you have taken so you can accurately describe what your expectations are and any areas of concern that you have when you meet with the contractor. Be as specific 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.

    Get all of your 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.

    Signing the Contract With a San Mateo County Deck Cleaning and Restoration Company in the Cities of Daly City, San Mateo, Redwood City, South San Francisco and San Bruno
    When you feel satisfied with the information you have received from your San Mateo County deck cleaning and restoration company you are ready to sign the contract. Be sure that they have a phone number so you can always be reached.

    Expect the contractor to stay within the estimate. However, if the actual cleaning and restoring costs exceed the original amount of the estimate, the deck cleaning and restoration contractor must get your approval before moving ahead.

    Getting Ready for Your Deck Cleaning and Restoration
    Professional deck cleaning and restoration companies 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 cleaning and restoring your deck 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.

    Trim plants and bushes that are in the way of your deck 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 cleaning and restoration contractor will be focused on cleaning and restoring your deck 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.

    Remove any furniture or movable items from the deck area. Before they begin work on your deck, remove anything that may be in the way such as barbecues or deck furniture. 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 cleaning and restoration 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 the cleaning and restoring of your deck begins.

Frequently Asked Questions
FAQ for Patio & Deck Cleaning Companies

Q: Why choose a Diamond Certified deck cleaning and restoration company?
A: Diamond Certified helps you choose a deck cleaning and restoration company with confidence by offering a list of top-rated local companies who have passed the country's most in-depth rating process. Only deck cleaning and restoration companies 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 ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you'll feel confident choosing a Diamond Certified deck cleaning and restoration company.

Q: Can't I clean my own deck and patio with bleach and dish liquid soap?
A: Bleach is not recommended for use on your deck. Lignin glues the wood fibers together and bleach attacks this. This causes the wood to break down. Also, if you use bleach on your deck, it causes bleaching of the wood to an unnatural white color. When a sealer is put over this, the appearance becomes blotchy. Most of the patio and deck cleaning products in your local stores contain bleach.

Q: Is it necessary to maintain my deck?
A: Discoloration can occur in only a few months. While pressure treated pine is long-lasting, it can begin to splinter long before it is considered old. That is why most home owners do a regular cycle of deck maintenance. Your deck may not rot, but its appearance will be affected without regular maintenance.

Q: Is it necessary to seal a new deck or patio?
A: It is important to seal a new deck a few weeks after it has been completed. This protects your deck from splintering and discoloring.

Q: What is the recommended maintenance for decks?
A: Once a year, check for loose boards and nails and clean your deck thoroughly and reseal it. Regular maintenance by a deck cleaning and restoration contractor will save money over the long term.

Q: Why do I need to maintain my deck and patio?
A: Wood decks and patios are easily damaged by weather, especially moisture and the sun. But use and location also play a part. Without proper maintenance, the wood's lignin breaks down and causes the wood to split and discolor. Also mildew will grow and cause more damage. It is important to schedule regular maintenance to keep your deck in good repair and looking like new.
