"Working with Wasco was a great experience all around, both sales and installation. We intend to use them again in the future to replace additional windows. They were incredibly knowledgable and professional. We would rate them an A++"

"Excellent contractor . Great to work with . B & K replaced the window glass in Five Thermopane windows. The window frames were still good so that is why I chose the glass replacement option. Cost, of course, is then far more reasonable. Our windows now are clear - no fogging anymore."

"We had two windows replaced and they look great. We had old, outdated, drafty windows, and now we have beautiful, secure, functional and high quality windows that have kept in the warmth this winter! The windows that we ended up getting have features that we didn't have before and we love it all - the ability to move the screen up and down, easy tilting options to make cleaning the windows so easy, locking mechanisms, etc. The ordering process was easy, and staff were friendly."

"We had 6 large windows replaced. Throughout the project, the communication was perfect. We had Brian and Luis install the windows. They were fantastic. They were very personable, communicated on any issues they saw during the install, and completed the entire project in one day. They were thorough and the windows look perfect. You can tell they take pride in their work. If you want windows installed without any issues, Weather Tight is easily the best choice."

"They were very pleasant and very meticulous. My windows have never been this clean. They cleaned the windows, screens and wiped out the window wells. Were there for a long time but cannot really complain as they provided a wonderful service!"

"Met with Alec about 3 windows. He was so enthused and confident about the windows his company sells, we agreed to go with them. Price was good, time out for delivery seemed good. Alec was very easy to work with, explained everything we needed to know. Thanks and can't wait for the windows."
