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

Settling & Structural Sounds

Popping/Cracking:

  • Most noticeable during first 1 to 2 years
  • Often heard during heating/cooling cycles or day/night transitions

Creaking:

  • Wood framing adjusting
  • Normal as lumber dries and settles
  • May be more noticeable in certain weather

Try This First:

  • Monitor - sounds should decrease over time
