Three things really stood out for me about House Smart Home Improvements. The salesman was very professional even when I changed my mind he simply accommodated me. The man who did the installation was amazing and did a terrific job. The pricing was good, and the windows have a lifetime warranty. These were all very good, but I simply could not be happier. I will be using them again when finances allow for other windows. I cannot express enough how happy I am with the work. The windows have not leaked at all and they are just beautiful. I will be telling all the neighbors about my experience!
