Carpet Moisture Issues
Moisture beneath carpet is a serious issue that can lead to mold growth, persistent odors, padding deterioration, and backing delamination. Because carpet and padding act like sponges, they can trap moisture against the subfloor for extended periods — creating ideal conditions for mold and bacteria.
Key Takeaways
- Mold can grow beneath carpet within 24-48 hours of moisture exposure
- Musty odors are often the first sign of hidden moisture and microbial growth
- Subfloor moisture from concrete slabs is a common hidden source
- Padding absorbs and holds moisture, extending drying time and mold risk
- A certified inspection uses moisture meters, thermal imaging, and visual assessment to identify moisture sources
Frequently Asked Questions
Yes, carpet wrinkles can often be corrected by power stretching. However, if the backing has delaminated, re-stretching won't solve the problem.
Our Standard Flooring Inspection starts at $550 and covers carpet, including installation evaluation, backing assessment, and a written report.
