It protects the insulation and the underside of the mobile home, preventing costly repairs down the line.
What to Look for in Mobile Home Underbelly Tape
When I was shopping for underbelly tape, I focused on a few key features:

- Width and Length: Depending on my specific needs, I looked for a tape that offered a variety of widths and lengths. I found that wider tapes were better for larger gaps.

How to Apply Underbelly Tape
When I finally got my hands on the right tape, I followed these steps for application:
- Clean the Surface: I made sure the area was clean and dry to ensure the tape would stick properly.
- Cut to Size: I measured and cut the tape to fit the gaps or holes I needed to seal.
- Apply Firmly: I pressed the tape down firmly, ensuring there were no bubbles or gaps.
- Smooth the Edges: I ran my hand over the edges to make sure they were secure.
- Inspect Regularly: I made a note to check the tape periodically for any signs of wear or damage.
