Windows, something everyone needs, yet nobody really wants to buy. Our home was built in 1965. When we purchased it, it still had the original Andersen Beauty alone series of windows in it. While most did not open due to being 55 years old, the frames themselves were in good shape. I started my window search with Renewal By Andersen, Pella, and then I happened to stop into a little shop on Route 19 named Blyth & Shearn. I met with one of the business partners, Gregg. Gregg proceeded to show me the offerings which Andersen, Lowen, etc have to offer. Gregg scheduled me promptly to come out and measure

I had six Anderson windows and three Anderson sliding doors replaced in my house three years ago. The caulking used has separated at the joint between the doors and casings enclosures. Two weeks have past since the salesperson "Gregg " was informed. This slow response isn't the way first time it's happened. The reason for this review is because one of the members of the original installers team stole a prescription of opioids pain killers from my bathroom medicine cabinet, and also the slow responses to needy adjustments. I didn't do a review initially after this happened
