We had wall anchors installed by Thrasher on the east wall of our basement in 2005 and have had no problem since. We just had the west wall done and we are very satisfied. Thrasher did a very professional job! Fausto and his helper worked quickly and told me what I needed to know about maintenance. They were good, hard workers and the clean-up was terrific! If someone ever asks me I will surely recommend Thrasher!
