Cayman Windows And Doors

we have a door and a screen door. The door is too short.they put in a sill plate that wasn't required for run off. The door has a large window in it. because of the shortness of the door it looks odd. All of this caused a tripping hazard. My husband has mobility problems and is at risk for injury. The screen door rattles at the bottom. I want a new door with no tripping hazard. Complete waste of money. Now we have a new tripping hazard in our home and we're can do nothing about it. We decided to go with a local company to help the small business but that was wrong. The only response I got was "that's the way they make them. I assumed they make the doors but they only make the windows. It took a long time to save the money for this project, waste of time and money. They sent an installer to correct the problem. He could only lower the sill a half an inch. There is a cold draft coming from under the door. The company owner said that is normal. If I want to stop the draft (not completely) then they will send someone to put the sill back up. The sweep on the door can't be lowered. The door is too short. I've decided to leave the door the way it is and hope nobody gets hurt. A half an inch lowered is better than nothing. Very unhappy.
