Anyone can tell me how much is cost to replace a carpet in 4 beroom house,just the cheapest one?

Answer 1

Measure your rooms, calculate the square footage, add 5% for approximate sq. ft.

You can find carpet starting at about $3.00 per sq. ft.
Bear in mind that works out to $27.00 sq. yd. You may find a few for less.
There may be extra charges for pullup and extra furniture.
9 sq. ft. = 1 sq. yd.

Don't fall for ads that offer three rooms for a set price. They are gimmicks/bait and switch and they cannot do it, but will high pressure you into high and "overpriced" carpet.

Find legitimate dealers. Established Mom and Pop stores.
