Noise Issues
New homes make sounds as they settle and materials adjust to temperature and humidity changes. Most noises are normal, but some may indicate issues needing attention.
Common Home Sounds
Pipe Noises
Water Hammer (Banging):
- Occurs when water flow is suddenly stopped
- Common when quick-closing valves shut (dishwasher, washing machine)
- Usually heard in walls near these appliances
Ticking/Clicking:
- Hot water flowing through pipes causes expansion
- Pipes cool and contract when hot water stops
- Normal, especially noticeable at night when house is quiet
Try This First:
- Note when noise occurs (during water use? after?)
- Identify location of noise
- Check if water pressure seems unusually high
Is It Covered?
| Issue | Covered | Period | Notes |

Settling & Structural Sounds
Popping/Cracking:

- Normal as lumber dries and settles
- May be more noticeable in certain weather
