About how much would it cost to re-carpet my room?

Basic carpet will go for around 3$ (+-) a s/f installed with a basic pad. You ll need a pc 12x21 and that ll have several "T" seams along one wall. Or a pc 15x17 and no seams but will be 3 more s/f. I d go seamless and get the extra 3 s/f.

If your carpet isn t glue down now and its a standard install , it will run from free rip out to 50 cents a s/f (about 100/125 $) One thing you may run into is disposal of the old and that can run from 75 /100$ All these prices vary from area to area but your looking at 1000$ for all you ve listed.

Any questions you can e mail me through my avatar. GL

Depends on where you live, and the quality of the carpet. If it's a medium quality, and you don't live in an expensive area; around $400.

we need to know how much the carpet is.
