Can I reuse carpet padding?
Hereof, how often should you change carpet padding?
A good rule of thumb for carpet padding is to replace it every five years. Your carpet may be in better or worse shape, though, so you will have to do an inspection to decide what shape it's in.
Accordingly, how long does carpet padding last?
With a good rubber pad, you could expect it to last 10 to 20 years. Urethane carpet pad is currently the best pad on the market. It provides you with a soft and durable floor. Under normal circumstances, you could expect a urethane pad to last 15 to 25 years.
It sits under the carpet for years, and the only time you really think about it is when it is under-performing or when you are replacing your carpet. If your carpet pad is worn out, but the carpet is in good shape, you could actually replace just the padding.
