Loud bangs coming from the loft
There are very loud bangs coming from the loft in my new build apartment I’ve recently moved into, mostly during the night when the temperature drops and again in the morning when the sun rises. These sound like loud thuds and nails popping. My guess is thermal contraction as the loft is constructed of metal and wood. The loft does not have easy access. How would I go about getting this inspected and what field of work should I be contacting?
========================
Answer-
Based on your description, it does sound like the noises are likely due to thermal expansion and contraction of materials in your loft, which is a common occurrence in buildings, especially newer constructions. To address this issue, you should consider the following steps:
1. Contact the building management or landlord:
If you’re renting or living in a managed property, inform them about the issue first. They may be aware of similar complaints and might have a process in place for inspections.
2. Consult a building inspector:
A certified building inspector can assess the overall structure and identify potential issues. They can also recommend specific experts if needed.
3. Seek a structural engineer:
A structural engineer can evaluate the building’s design and materials, focusing on the loft area. They can determine if the noises indicate any structural concerns.
4. Consult an acoustician:
An acoustician specializes in sound and vibration. They can help identify the exact sources of the noises and suggest mitigation strategies.
5. Contact a general contractor:
A experienced general contractor, particularly one familiar with new builds, may be able to inspect the loft and suggest solutions.
6. HVAC specialist:
Sometimes, these noises can be related to heating and cooling systems. An HVAC specialist might be able to identify if the issue is related to ductwork or vents in the loft.
When contacting professionals, describe the issue in detail, mentioning the timing of the noises and your suspicion about thermal contraction. If possible, try to record the sounds to help with the diagnosis.
Remember, as this is a new build, the property may still be under warranty. Check your purchase agreement or contact the developer to see if they will address this issue as part of their after-sales service.
