Clicking sounds in your walls can make you uneasy at night and disturb your sleep. But what are they and where do they come from? Could your house be haunted? Is there an animal trapped inside? Probably not. There is a perfectly rational explanation for all this. Basically, it could be the expansion and contraction of the pipes in your attic. Also, it could be a loose wire behind the wall. Don't worry, there is a solution!
The clicking sounds comes from the contraction and expansion of the pipes as they are warming up. The sound is made by the pipe rubbing off a joist as it expands. This is not a problem with the pipes even if they were properly installed. It is simply what happens when they heat up and there is no cause for alarm. This can be fixed using other materials. Proper insulation is all that is needed.
What else could cause it?
A loose wire can also be the problem of this clicking sound. If you have a lamp that is flickering, it could be a sign that this is the problem. This needs to be sorted out as soon as possible as a fire could occur or you could be in danger of an electric shock. A loose wire can cause a clicking sound when it hits off the wall. It could also be that appliances are not wired correctly. In the case of lights, it could be that the wrong bulb is being used. Be sure to call an professional electrician straight away.
How do I fix it?
If it is a problem with the pipes, this can be fixed by putting some foam under the pipes where the noise is happening. Lift the floorboards and locate the spot where the clicking sound is heard. You can also use a piece of carpet. This stops the pipe from touching the joist while it expands. If it is a wiring problem, you need to call a professional electrician to sort it out. Turn each appliance off one at a time and see if you can locate where the clicking is coming from.
Never try to fix a heating or wiring problem yourself as it could be dangerous, especially regarding the wiring. If it is a loose wire you could get a shock. If it is a pipe issue be careful in the attic if it is not converted or you could get an injury or have an accident. It is worth spending the money on a professional who can fix the issue and put your mind at ease. If you are not sure about something, leave it alone until you get a professional to help you.
