Hi, my name is XXXXX XXXXX I'll be working with you today.
Most of my subcontractors use 20% overage for carpet, 5% for padding, 10% for sheetgoods (vinyl), and 5% for hardgoods (laminate, tile, hardwood). This percentage is added to the square foot or yard measurement of your area to be covered.
It seems to always work out about as close as it can be guessed.
For carpet, small jobs can obviously be estimated much more closely. For instance, in one room is easy to determine where a carpet seam will have to go and if the carpet waste can be turned to work in a closet, etc. Multiple rooms and more chopped up floorplans are much more difficult to nail down exactly. If a room is the same width as the roll with a fairly simple floorplan then 10% would be enough to consider for waste. Most rolls are 12' wide but many styles are now available 15' wide.
I hope this helps. Please let me know if I can be of further assistance. Thanks, P.J.
So would you recommend measuring the carpeted area from wall to closet and then adding 15% percent or so? Or does measuring from the farther point to the farthest point take into account the scrap? (measuring from a the deepest part of a closet for example to the opposite wall would seem to take into account the scrap cut out for the closet framing, door etc.)
What do you use to estimate subfloor for vinyl, such as 1/4 luan?
