Everything from start to finish went smoothly. I learned about Green Star when they visited my neighbor. They were canvassing door-to-door. The representative who knocked on my door was professional, informative, and not pushy. I did all kinds of research before inviting them back to my home to provide more information and a free price quote which is good for a year. During this session which took two hours (I had lots of questions). The representative was extremely patient. All windows were custom sizes. Windows were all measured and a quote was provided. I deposited $7,000 and the balance was paid at completion. The windows are manufactured by Slocumb. They come with a lifetime transferrable warranty which covers the basic window unit, hardware, insulated glass, and glass breakage. Green Star also has the Good Housekeeping seal of approval. The windows also have a limited lifetime warranty from Slocumb which covers the vinly, glass and hardware. I purchased all premium windows with the following ratings: water - 7.50psf/DP50, structural - DP50, U-Value 0.26 and R-Value - 4. My windows are all dual glazed with Argon and have insulated frames and sashes. Within less than three weeks of placing my order, the windows were and installed in two days. The installation team was professional, customer-friendly, and are welcome in my home anytime. My team included Anthony, Walter, and on day one Skippy. Everyone arrived on time and worked very hard all day long even in hot weather. They cleaned up after themselves and respected my property at all times. I am thinking about inviting them back to install a new front door and to replace some weathered wooden shingles with vinyl shingles in the future. I absolutely love my new windows and trim. I can't believe what a difference my windows make with noise reduction and energy efficiency. The aesthetic improvement is awesome too. Thank you Green Start! I highly recommend this company.
