What Our Clients Are Saying

  • "Our Window inserts are working great. It has made a major difference in our bathroom. I no longer get goosebumps after getting out of the shower. We have no complaints, what so ever. They have also cut down the outside noise dramatically. The only problem being that we can no longer hear our wind chimes. The Window Inserts were much simpler and less expensive than magnetic inserts or new storm windows. Alan and Keith of Window Efficiency Works were very thorough, professional and easy to deal with. I'd recommend them to anyone who asked."

  • "Great To Be Warm!


    I just bought my home right before winter. After the first rounds of sub freezing weather and a cold house, I began searching online for solutions. Living in an historic district with very clear guidelines, solutions narrowed pretty quickly. Interior storm windows became the hands down way to go. Alan and Keith were great to work with: Prompt, professional, courteous, and thorough. Needless to say it is so nice to have a warm home. 90 year old widows get pretty leaky over time and interior storms help maintain the architectural integrity of the house, while providing the necessary heat loss prevention. I have a few more windows to do upstairs and I will not hesitate to go back to Alan and Keith."

  • "Installation was top notch. Alan and his crew were very considerate of our house and belongings and cleaned up behind themselves. I was very impressed. The Climate Seal window inserts are great. First thing, we could tell a reduction of outside noise. Second, our gas bill was reduced $65 in April 2011 compaired to April 2000. So far our power bill for 2011 is far below 2000. Our 90 year old house is warmer in the winter and cooler in the summer. Climate Seal window inserts are a great investment. Thanks Alan."
