Very polite, courteous and professional. Hard to imagine finding a Sotheby's level appraiser in the center of Long Island! Appraised my items VERY well and even set me up with an auction house! The antique dealer offered me a fraction of what he showed me my stuff sells for! The do buy a lot of things outright from you, if you are interested in selling. Especially old guns. But call ahead, as they are on the road a lot.
I have a historic home (1871) and when I look for items to decorate or architectural pieces such as a door or hinges I always shop at Colonial first. Saves a lot of time and frustration when you know it's there and the prices are in line with the antiques.
Wow! This establishment always provides a fresh inventory and great customer service. If you are looking for furniture then you have found the place. Love it! Best furniture/antique/designer/vintage store I've been to.
