Frequently Asked Questions
How much does carpet padding cost per square foot?
Carpet padding costs $0.30-$1.20 per square foot installed in 2026. Standard 6-8 lb rebond is $0.30-$0.80; memory foam and moisture-barrier pads are $0.80-$1.20.
What thickness of carpet pad is best?
7/16 inch at 6-8 lb density is the sweet spot for most residential carpet. Anything thicker than 1/2 inch can flex too much and void warranties.
Do I need special pad for stairs?
Yes — use 7-8 lb high-density rebond, 3/8 inch thick. Standard 6 lb pad compresses too fast on nosings and voids most stair warranties.
Is memory foam carpet pad worth it?
Yes for master bedrooms, home offices, and anyone with joint pain — memory foam ($0.80-$1.20/sq ft) adds noticeable comfort but is unnecessary in low-use rooms.
Can I reuse my old carpet pad?
Only if it's under 5 years old, undamaged, and matches your new carpet's density spec. Most installers recommend replacing pad together with carpet.
Does carpet padding affect the R-value?
Yes — 7/16" 8 lb rebond pad adds ~R-1.2, which reduces heat loss on ground-floor rooms and basements by 3-6%.
