I have to compliment Jennifer Borsh of Blyth & Shearn Windows, McMurray PA. Jennifer went the extra mile to assist us with ordering parts for our Anderson Windows! She responded in record time and was very helpful. Great Customer Service. Thanks so much

Report
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, but I sincerely think it's not o bad idea to put what happened on yelp so other folks can keep this in mind.
