"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++"

"Brian and Kurt were great. We had our 30 + year old Anderson windows removed and replaced with new glass. This is much less expensive than a full window replacement, and is possible when the basic window frame is still in good condition. Super happy with the result."

"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 We had old, outdated, drafty windows, and now we have beautiful, secure, functional and high quality windows that have kept in the warmth this winter!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."

"The team that came out were friendly, business like and were working all the time. The windows were all done by hand, not spraying a solution on them and letting them to drip dry. This experience was a welcome pleasant experience. I will speak well for them and use them again."

"I have an older house with some "troublesome" windows. The gentleman did a thorough job of cleaning them. He also was very patient with some of the problem windows. I was very pleased with the care he took in putting screens and storms back in the window frame. I would recommend him highly."

"Mr Atkins was very knowledgeable about the windows that he was selling, very friendly. Mr Atkins was not pushing me to buy the windows which I like. Once again thank you for your professionalism. I look forward to getting my new windows installed! Kelly"
