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.


When donating property that exceeds $5,000, it is required by the Internal Revenue Service to submit a professional appraisal summary with your tax return. We will prepare a precise and comprehensive report that will ensure that you, as the donor, will receive a full tax deduction from the IRS.

In today's world many people are opting for virtual inspections. Depending on the value and amount of items you have we are happy to discuss if this would be of benefit to you.

Do you need a certified expert to walk through your home or an estate you are handling to confirm that you're not disposing of something you shouldn't be?

Don't Take Our Word for It

Heather, this looks great.  It is very impressive to get this all done so well and so quickly.  Thank you!

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!


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.
