It took too long from order to delivery to get a single patio door. Summer hadn't started when we ordered in May and were told it could take 8 to 12 weeks. Installation finally happened on the first day of autumn. There was no communication or follow-up during the entire waiting period unless we initiated it. A call from TWADC explaining the delay would have shown some concern for the customer. The installation was completely different. The installer was skilled, professional and efficient. The product is excellent and exactly what was promised. If you don't mind waiting and don't care about post-sale customer service this is the company for you. When you do finally get your order you will be satisfied.
