David is a very nice and responsible guy. I find him on the website. He is a genius in installing doors. I need a patio door exchanged. After we talked over the phone, he set my reservation immediately. It was the next day David came to my house to measure the door size and accompanied me to choose a very nice patio door. On the day the door was delivered, David spent the whole day installing my patio door. As you know, the patio door is both large and heavy, only the skilled man can install it perfectly. David did it!! He carefully checked the strike plate and the metal piece on the jam where the door latched to make sure it is not too low or too high. David also checked the hinges to look for uneven lines. The gaps all around the door were same all the way. We can’t see any imperfection about David’s work. My patio door was finally installed beautifully. I love my patio door so much that I can’t thank David any more. The price for installing the door is very reasonable. In the end, David gave us free lubricant, paint, brushes, stain marker, etc. David also came and helped clean the patio the other day, for which I appreciated a lot. David is a responsible man for installing doors, if you have any kind of doors for installing, don’t miss such a good man.
