I went with MajorBrands/Abbey because of their glowing reviews for careful installation, and wasn't disappointed. And, their showroom staff were extremely knowledgeable and patient. They gave very candid, helpful advice to help distinguish the different options, and were prompt, flexible, and helpful start to finish. They're probably not the least expensive for installation, but I'm sensitive to the surprise hidden costs of cheaper installs, like having to repaint miles of baseboard or pay for damage to hallways in my condo. We wouldn't hesitate to recommend these folks!
