I bought 17 replacement windows made with vinyl from Houston Window Experts and I am very pleased. The did not use pressure sales tactics and they did exactly what they promised to do. I was impressed with their knowledge and the fact that they had so many brands to choose from. I was able to get the window that worked for me and for my budget. Their installers were very good also. They were neat and tidy and spent plenty of time installing each window to make sure it was level and plumb. They also used some special foam with a pointed wand that went between my windows and the house to give it a better seal. Overall I am very pleased and will recommend them to my friends who are looking for new windows.
