Measuring for carpet
I am replacing the carpet in 3 bedrooms, and measured the space at about 672 square feet. The carpet company I'm working with came out and measured, and they came up with 828 square feet, 156 more than I measured. It's just 3 basically square rooms and one closet, so not that difficult. I expected their measurements to be a little more, but goodness, that's a whole 'nother room! I measured carefully, with 2 people. I knew they would add some for waste, but this seems like too much.
Is that much difference to be expected? I'm thinking of going to a different store.
