We want to install laminate flooring in our family room, and had someone out to measure the room and bid on the job. He claims that there's a hump in the floor that makes it impractical to install Pergo.
He did this by sight and didn't use any tools. We can't see a hump. We didn't consider him reliable (and had to ask him to leave the house after a few minutes; he was argumentative).
How can we tell before ripping up the carpet if the floor is level enough for the flooring we want? The house was built in 1986. This room has a wood subfloor, and is over a basement. There are no poles, beams, or supports beneath this room -- no obvious cause of a hump.
