Public Insurance Adjusting

As your public insurance adjuster, we will be your advocate in getting your property damage claim adjusted and settled. For over 35 years we have exclusively represented policyholders to help them maximize their insurance claim recovery.

Business &
Real Estate

We represent clients in various types of residential and commercial real estate matters and business transactions. We provide continual legal guidance throughout the process to assist our clients no matter what challenges they face.

At Biller, Sachs & Robert we have represented only policyholders for over 35 years. Many public insurance adjusters, insurance agents, contractors, remediation companies, and other insurance professionals recommend their clients to Attorney Biller and his team when they encounter a problem or difficulty with an insurance company. The attorneys at Biller, Sachs & Robert know insurance policies and they know how to resolve insurance claims. When our firm is retained early in your claim, you won't need a separate public insurance adjuster or an unauthorized person to negotiate for you. With our experience, your claim will be timely submitted, policy conditions complied with, and settlements maximized. It is our knowledge, experience, and reputation which can allow us to resolve your insurance claim informally and quickly. When you hire us you get the benefit of a public insurance adjuster with the knowledge of an attorney.

If you receive a denial letter and you do not agree with the denial or do not understand the basis of the denial, you should contact our office to review the facts of the claim and the insurance company’s position. We can assist you in reviewing the loss and the insurance company’s reasoning for the denial. Denial letters also state the timeframe by which you must sue. It is important to remember that if your claim has been denied, you must file a lawsuit within the time set forth in your policy or your rights will be lost. We recommend you reach out to us for assistance if you disagree with the denial or need assistance requesting the insurance company reevaluate its position as soon as possible.
