I provide estate appraisals for probate, estate taxation, estate planning, and family equitable division. Our estate appraisals are based upon Fair Market Values and comply with the standards and guidelines put forth by USPAP, The Appraisal Standards Board by The Appraisal Foundation, and the Internal Revenue Service. I also provide insurance appraisals based upon a full Retail Replacement Value (“the amount it would cost to replace an item with one of similar and like quality purchased in the most appropriate marketplace within a limited amount of time"). In order to protect your property from loss by fire, theft, and damage an insurance appraisal is necessary. Our appraisal will provide your insurance carrier with a full and accurate catalogue description and photographs of your personal property. This facilitates claim settlements by providing detailed inventories and itemized replacement costs. We also assist individuals and companies of all sizes in managing, building, and selling their collections of art, decorative accessories, jewelry, and collectibles. For inventory and management we will prepare a detailed catalogued inventory with photographs of each item to organize and manage your collection. If you would like to build or sell your collection our contacts at many of the top galleries and auction houses can make this process easy and confidential.

With her extensive experience and educational credentials, she has established a significant footprint in the appraisal industry. Prior to founding Nadeau's Appraisals LLC, a firm dedicated to providing top-tier appraisal services, Heather honed her skills and expertise at Nadeau's Auction Gallery. Her tenure of over twenty years at this gallery was marked by a deep engagement with the art and antique market and provided her with hands-on experience and a deep understanding of object valuation. During her time at the gallery, Heather served in various capacities, each with increasing levels of responsibility. She developed a broad understanding of the business, including auction operations, client relations, inventory management, and object evaluation. Her commitment and expertise eventually culminated in her appointment as Vice President of the gallery. In this role, she was instrumental in shaping business strategy, overseeing operations, and leading a team of professionals. Heather's leadership at Nadeau's Auction Gallery not only underscored her business acumen and her grasp of the art and antiques market, but also her ability to successfully navigate complex, high-stakes environments.

My philosophy is simple: clients must be able to rely on our word, our work, and our judgment without question. By fostering trust and prioritizing ethical practices, I ensure that every appraisal we provide not only meets USPAP and IRS standards, but also reflects the confidence and respect our clients deserve.

Heather is wonderful to work with. We needed some antiques appraised for our mother’s estate. She was very easy to communicate with and responded quickly to all of our questions. Her research was thorough and helpful.

Wonderful staff, very helpful. I needed an appraisal for a piece of art that was handed down to me from my grandparents and Nadeau's did a wonderful job so I was able to get the art added to my home owners insurance policy. Highly recommend!

As an accredited appraiser, I always emphasize that estate appraisals are essential for accuracy and protection. They provide a fair market valuation of personal property for probate, estate tax filings, equitable distribution, or charitable donations. Without a professional appraisal, families risk disputes, inaccurate tax reporting, or undervaluing assets.
In many cases, yes. The IRS requires a “qualified appraisal” for estate tax reporting and charitable contribution deductions, and courts often require appraisals for probate. Even when not legally mandated, an appraisal provides an impartial record that protects executors, heirs, and fiduciaries by demonstrating due diligence and compliance.
I founded Nadeau’s Appraisals on the principles of honesty and trust. I provide USPAP-compliant, IRS-qualified appraisals backed by decades of experience in the auction and appraisal industries. Unlike firms that limit service areas, we never charge travel fees and serve clients nationwide, ensuring consistency, professionalism, and confidence no matter where our clients are located.
Do you need a certified expert to walk through your home or an estate you are managing to ensure nothing valuable is overlooked? Don’t risk discarding something of significance—one of our clients nearly lost a $200,000 painting to the trash before Nadeau’s Appraisals identified and preserved it.
I am proud to serve a diverse client base across the United States, with strong roots in the New England and Tri-State regions and an established presence in Florida. Our clients include private families, fiduciaries, attorneys, banks, and insurance providers, as well as museums, schools, and nonprofit organizations. Whether assisting with estate tax filings, charitable donations, or personal and corporate inventories, we bring the same level of professionalism and integrity to every community we serve—delivering trusted, USPAP-compliant appraisals without geographic limitation.
At Nadeau’s Appraisals, our fees are structured on either an hourly rate or a flat project fee, tailored to the scope and complexity of the assignment. In alignment with USPAP and IRS guidelines, appraisal fees are never based on a percentage of an item’s value or contingent on the eventual sale of property—ensuring objectivity, transparency, and independence in every report. While our standards and methodology mirror those of the largest national firms, our fees are generally significantly lower, allowing clients to receive a highly professional, USPAP-compliant product at a more accessible cost. This balance of quality and value has earned us the trust of families, fiduciaries, and institutions nationwide.
