Erez Gilad: Around the World

By James Florence, Diamond Certified Program Reporter

RICHMOND — Erez Gilad was raised on his family’s farm in Israel, and it was there that he learned the trade of his forefathers. As he matured, however, he began to develop bigger ambitions—ones that would eventually take him to the other side of the planet. “I moved to California in 2006, right after I completed my service with the Israel Defense Forces,” he remembers. “I had a friend who lived in the Bay Area and owned his own business, which was my dream. He told me about a colleague who was looking for someone to help establish a local restoration franchise. It seemed like a great opportunity, so I decided to take it. I started out doing carpet cleaning, just to become more familiar with the industry, and I gradually earned my general contractor’s license, as well as certifications in air duct cleaning and water and fire damage remediation.”

Today, as owner of 911 Remediation Inc., Erez says one of his favorite parts of his job is addressing the psychological aspects of the work. “When people experience a structural loss, they’re typically stressed, confused and angry. When we come into their homes with a friendly face and take control of the situation, it relieves a lot of their stress. I enjoy helping our customers and reassuring them that everything will be taken care of.”

Erez divides his time between the Bay Area and his home country, where he lives with his wife, Rinat, and daughters, Noya and Liya. When asked his favorite part about Northern California, he says he appreciates the harmonious integration of its diverse populous. “You have people from all over the world living together and accepting each other as human beings, which I love to see.”

Outside of work, Erez enjoys a variety of active pastimes, from soccer and yoga to running and swimming. “I also love spending time with my family,” he says. “We enjoy travelling all over the world and seeing new places, but we also like going to the beach and just playing in our backyard.”

When asked the first thing he’d do if he were to retire tomorrow, Erez says he would take his interest in travel to a new level. “I don’t know if I’ll ever retire—I’m the kind of person who always needs something to keep me going. However, if I did, I’d like to take a trip around the world. I recently read about a yacht that goes around the world in 180 days, which would be amazing.”

Ask Me Anything!

Q: Coffee or tea?
A: Coffee in the morning and tea in the evening.

Q: What’s your favorite local restaurant?
A: Betelnut in San Francisco.

Q: What’s your favorite thing to do on a rainy day?
A: Answer our customers’ calls, of course!

Q: What’s your favorite snack?
A: An Israeli peanut butter snack called “Bamba.”

Q: Do you collect anything?
A: Hats.

What To Ask In Person
Questions to Ask When Meeting with a Representative of the Alameda County Water and Fire Damage Restoration Company in Person

After you’ve interviewed several companies by telephone, it’s time to meet with a few in person.  You may do this in their offices, or they may want to walk through your home to see the extent of the damage.  You should not feel pressured to have anyone in your home if you are not comfortable; therefore, you may want to consider meeting in their offices first and arranging a walk-through by appointment during a time when you will be home with someone.  Always go with whatever is most comfortable for you.

When meeting with a company in person, there are some questions you should ask regarding their services:

General Questions:

  1. To ensure an accurate estimate, what process do you follow prior to giving an estimate of the cost of restoring my home?
  2. What processes do you use to look beyond the surface damage to determine if the structure of my home is still safe?
  3. What if the damage turns out to be more extensive than originally thought?
  4. How soon can you start?
  5. Is the work warranteed?  If so, for how long?
  6. What does the warranty entail and is it a written warranty?
  7. Once you start repairs, how long will it take to complete?
  8. Do I need to move out of my home while you work?
  9. Will a building permit be necessary?
  10. If a building permit is necessary, who will get the building permit?


For Fire damage:

  1. What if there is structural damage?  What will happen then?
  2. What do you do to eliminate the smell of smoke in my home and in my belongings?
  3. Is there anything I can do to facilitate this process?
  4. Will my home need to be inspected once work is completed?  If so, who will need to inspect the home?  The fire inspector?  A building inspector?


For Water damage:

  1. What if there is structural damage such as rotting wood?
  2. If you find mold or mildew, what processes will you use to eliminate the problem?
  3. Do you have certified mold remediation employees?
  4. Will my home need to be inspected once work is completed? If so, who will need to complete the inspection?  A building inspector or someone else?


Questions to ask regarding personal belongings:

  1. What items can be cleaned or restored?
  2. Do you have a “contents master” who will assess my belongings and ensure their restoration and return?
  3. If you remove items from my home to restore them, where do you take them?
  4. If something of mine is damaged further during the restoration process, what recourse do I have?
  5. If something turns up missing after you remove it from my home, what are the procedures you will follow to ensure it is located?

    It’s best to choose a Diamond Certified water and fire damage restoration 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 water and fire damage restoration company in Alameda County and the Tri-Valley Area, 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 find a Diamond Certified water and fire damage 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 water and fire damage restoration company.  Keep in mind, though, that references provided to you by the water and fire damage 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 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.

    Questions to ask references:

    1. What type of repairs did this company do for you?
    2. Did they do a thorough inspection of your home?
    3. Were the employees of this company courteous and helpful?
    4. Did they explain clearly what they were going to do so you could ask questions?
    5. Were you satisfied with the repairs and restoration work from this Alameda County water and fire damage restoration company?
    6. Was the work completed in a timely manner?
    7. Were you pleased with the work they did for you and the length of time it took to complete the work?
    8. If they removed items from your home to clean and restore them, were the items returned in a timely fashion and were they cleaned and/or restored in a satisfactory manner?
    9. Do you feel the price was fair for the work that was done?
    10. If you needed this type of service again, would you use this Alameda County water and fire damage restoration company again?
    11. Would you recommend this company to others who have experienced water and/or fire damage?

  • How To Work With
    Before You Hire a Company

    Cleaning up water after a flood, or leaking pipes, or a backed up sewer system can be messy, time consuming, and even hazardous.  Before you hire a water and fire damage restoration company, you will want to find out what safety precautions they take when working with possibly hazardous materials, and what you will need to do prior to them coming into your home, if anything.  In some cases, depending on the type of damage to your home, you will be told not to enter your home until its safety can be ascertained.

    Once you hire a company, in Oakland, Fremont, Hayward, Berkeley, San Leandro, Alameda, Union City, Pleasanton, Newark, Dublin, or one of the surrounding towns it will be important to maintain contact with the water and fire damage restoration company and your insurance company to ensure all work complies with safety standards and that your insurance company is aware of the work that needs to be done for the claim process.

    You should work with the water and fire damage restoration company to see if there is anything you need to do prior to, or during the restoration process.  Does the company need you to remove furniture, clothing, or other personal belongings from the home before they begin work, if it is safe for you to do so?

    Sign a Contract with the Water and Fire Damage Restoration Company
    When you are satisfied with the information your Alameda County water and fire damage restoration company has given you, and you are ready to proceed with the work on your home and belongings, you should sign a contract that includes a warranty for the work to be done.  In addition, you should contact your insurance company and let them know the work will be proceeding, and ensure they are in agreement and willing to honor any payments that need to be made to the water and fire damage restoration company.

Top 10 Requests
Top Service Requests

There are many reasons why someone may need a water and fire damage restoration company in Oakland, Fremont, Hayward, Berkeley, San Leandro, Alameda, Union City, Pleasanton, Newark, Dublin, and the surrounding towns, but the most common reasons someone would contact a water and fire damage restoration company in Alameda County are:

Water damage from roof leakage:
When maintaining a home, it’s easy to overlook the part that keeps the weather out, the roof.  Whether it’s a leaking roof, problems with chimney maintenance, a leaking skylight, or any other problems that can occur in and around a home’s roof, water damage can occur as a result of rain leaking through.  Sometimes leaks start out small and go unnoticed until the damage is extensive, requiring not just water cleanup, but mold remediation as well.  When this happens, it’s important to use a water and fire damage restoration company that knows how to deal with mold.  If a person is lucky, the damage will be noticed immediately and the response can be quick.

Water seepage:
Water seeping through floors, walls, or ceilings can be caused by leaking pipes, condensation developing in and around pipes, deteriorated waterproofing around bath tubs, sinks, and toilets, or water seeping into the home through the ground from underground pipes that have broken or groundwater that has collected against your home’s foundation.  When this happens, it’s important to know the source of the water and fix the problem while trying to prevent further damage to the home.  In addition to a water and fire damage restoration company, it is possible other specialists may need to be involved such as plumbers, or other contractors.

Plumbing issues:
Plumbing issues can cause mild or severe water damage.  Broken pipes can cause water to run freely into the home until the water is shut off.  If the broken pipe is discovered quickly, water damage may be minimal.  If it is not discovered for some time, water damage may be extensive.

Problems with sewage removal or septic tanks:
When sewage systems back up or septic tanks overflow, water damage can occur that can be very hazardous to humans due to the heavy concentration of bacteria.  If water damage occurs in the home that includes wastewater from a sewer or septic tank, special care will need to be taken, including special equipment, to clean up any water damage from the overflow of a septic tank or backup of sewer pipes.

Heavy rains and flooding:
Through regular maintenance and monitoring of our homes we may be able to prevent some forms of water damage; however, heavy rains and flooding can cause sudden and unpreventable water damage to our homes.  Often times this type of damage is severe and may be hazardous as flood waters may contain sewage or chemicals that are harmful.  Additionally, the force of flood waters can cause severe structural damage that can make the home unsafe.  If this occurs, it is imperative that special care be taken when cleaning up and repairing/restoring our home.

Cooking/Grease Fires:
Most often cooking and grease fires occur in the kitchen or wherever a barbecue is used.  Grease fires can occur when cooking oil is brought to too high a temperature, causing it to ignite.  If water is thrown a grease fire, it can cause the grease to splatter and the fire to spread.  If the fire is put out in the correct manner the damage to the home may be confined to the kitchen, or a localized area within the kitchen; however, smoke and soot damage may be extensive.

Electrical fires:
Electrical fires can be caused by short circuits in wiring, overloaded circuits, sparks, or when bare electrical wires come in contact with a flammable substance.  These types of fires can cause extensive damage throughout the home due to most wires being located within the walls of the structure.  Electrical fires may cause a homeowner to have to vacate their home for an extended period of time while repairs can be made.

Other types of fires:
Fires can result from equipment and appliance malfunctions, problems with furnaces or fireplaces/woodstoves, or through carelessness with flammable items such as cigarettes, lighters, and matches.  Whatever the cause of the fire, it’s important to note that smoke and soot damage may be extensive and clean up should be done by a professional.

Q:  Why should I hire a professional Contra Costa County Water and Fire Damage Restoration Company instead of doing the work myself?

A:  Water and fire damage may result in your home being contaminated with toxins, including mold and chemicals, and it can affect the structural integrity of your home.  Unless you are knowledgeable about the proper protection and disposal of toxins, and are sure your home is safe to enter, you should trust a professional who is licensed and certified in the area of water and fire damage restoration.

Q:  What are some common issues created by water damage?

A:  Water can ruin your property and compromise the structure of your home.  Carpets and wood floors can rot and mold can grow, which can affect the health of you and your family.

Q:  What is the water restoration process?

A:  A member of the water and fire damage restoration company will inspect the damaged area and, if possible, attempt to stop the water from creating additional damage.  Then the company will extract any standing water from your home and dry your home using dehumidifiers and fans.  Once your home is dry, the company should test for moisture and mold spores to ensure the process is complete.

Q:  Water is coming into my home?  What should I do first?

A:  Stop the water from coming into the home, if you can, but do not walk into the water if there is any possibility of electrical hazards.  Contact a Contra Costa County water and fire damage restoration service to start any emergency procedures.

Q:  Should I move furniture and other belongings from the affected areas?

A:  Only if it is safe to do so.  If there is any chance of electrical hazards being present, do not go into the wet areas until they have been cleared by a trained water and fire damage restoration person.

Q:  I’ve had a fire in my home.  Can I go in and start cleaning?

A:  It’s normal to want to go into your home and begin the clean-up process, but until all hazards have been addressed, it is better to remain outside of the home until a professional has determined it is safe.

Q:  Soot covers everything and I’m worried it will damage my belongings.  Can’t I start removing it right away?

A:  Soot in itself can be damaging, but if soot is mixed with the oils on your skin, it can become even more corrosive and cause further damage to your belongings.  It’s best to let a professional, who has special equipment, come into your home and remove the soot.
