Our entire home is furnished with windows and storm doors by this business where Ed Curtin is the manager. I couldn't find enough superlatives to express how please we are with the customer service extended to us , even years after the last installation.If customer service is the standard by which a business is to be judged then GNH is a model of business to be emulated. Mr. Curtin was prompt, efficient , courteous and professionally experienced in meeting our requests for service. My only regret is that we no longer have any windows or doors to be replaced or added. Considering our experience it is no surprise that they continue to be in business for as long as they have. If you want quality and service GNH Latham is the place to go!!!
