No, a properly installed carpet should not lift up. Lifting indicates a problem with installation or underlying issues.
Reasons Why Carpet Might Lift:
- Loose Edges: If the carpet edges aren't secured to the subfloor or walls using tack strips, they can lift and buckle. (Source: Signs of Carpet Buckling)
- Poor Installation: Improper stretching and securing of the carpet during installation can lead to lifting, particularly in the center. (Source: Should you be able to lift the center of carpet? : r/NoStupidQuestions) A professional installation should result in a carpet that is difficult to lift.

- Subfloor Issues: Uneven subfloors can cause sections of the carpet to lift. This is especially true with carpet tiles where improper subfloor preparation leads to poor adhesion. (Source: Cimex causing carpet tiles to lift up at seams? | Mikey's Board)
- Moisture Problems: High humidity can cause carpets to swell and lift. (Source: Understanding and Fixing Carpet Buckling: A Complete Guide)
What to Do If Your Carpet Lifts:
- Check the Edges: Examine the edges for loose sections.
- Assess the Subfloor: Ensure the subfloor is level and even.
- Contact a Professional: If you can't identify the problem, contact a carpet installer for repair or reinstallation. A small lift might be easily fixed by pushing it back down, but larger issues require professional intervention. (Source: flooring - How do I lift a fitted carpet without damaging it? - Home ...)
