Complete DIY Guide
You can replace carpet padding yourself if the carpet is in good condition and you have basic tools, but the process requires carefully pulling the carpet back, removing old padding, installing new padding, and re-stretching the carpet over tack strips. Carpet padding replacement costs $0.50 to $1.00 per square foot for materials â roughly one-tenth the cost of full carpet replacement. Replacing padding alone can extend carpet life by 3-5 years, eliminate musty odors, restore cushion and comfort, and improve energy efficiency through better insulation. The job requires 4-8 hours for an average room and is within the skill range of most DIY homeowners, though large rooms and complex layouts may still warrant professional help.
