He installed a Phantom Screen Door for me that I purchased from Lowe's, Bedford. The purpose of this e-mail is to express my complete satisfaction with the service that I received from Bob. He is a true professional in all aspects of his trade. He provided "above and beyond" customer service for me and my wife. We are in a condo association with a total of 90 units and you can be assured that I will spread the word about Granite State Glass for both Phantom Screen Doors and any glass needs. As a retired JCPenney management associate, I welcome this opportunity to compliment an individual like Bob Knapp. Please convey a final "thank you" to him.

BR: Belmont, NH Today we had Henry and Shaun at our house. They were scheduled to arrive at 8:30 and arrived at 8:32. They brought their tools into our breezeway and then put on blue booties every time they had to go into the house. When they had to go out to their truck, they removed the booties and then put them back on when they came back into the house. I have to say that they were very professional in everything they did. They cleaned up after the job was done and handled themselves well throughout. They also made sure everything was done just the way we wanted. I have worked in the trades for 28 years. I have to say that I never worked with anyone that handled themselves any better. Thank you for a job well done. DM; Laconia, NH Very friendly and professional. Their work was first class.

They came on time, were courteous and respectful coming in and out of the house through the whole process, and the windows looked cleaner than any I’ve cleaned in my life. The installation was professional grade with the touch only a caring homeowner would give. They truly treated our house like their own. I would recommend Granite State Glass, Harvey windows, and especially Art to anyone! ML; Manchester, NH Thank you for the wonderful job Tom and Bob did on our shower glass installation. Tom and Bob were careful and paid sincere attention to detail in the installation. They did a spectacular job cleaning up after their work and I thank them for that.

Tom and Bob are valuable assets to the fine reputation of Granite State Glass and I will surely recommend your company to my friends and clients. KB; Temple, NH We have been wanting to install new windows in 4 of our motel rooms. We did a lot of pricing and comparing of quality for a couple of years. When we called your company the salesman was very helpful and informative and best of all we felt we were getting the fairest price. We had six windows installed in September and we are very happy with our choice. They were installed on the date we asked for and the gentleman that put them in did a great job. They look and work even better. Thank you again for the great customer service and please let the salesman and installer know that they are doing a great job and that your customers appreciate everything they do, DG; Intervale, NH Done Fast...
