 Re: Best method to find joists ?
I normally tap the ceiling with the knuckle of my index finger and listen to the sound it makes. When it becomes a dull thud instead of a hollow noise you've found or are pretty near to the joist.
I use a laser line fixed to the ceiling to mark out the positions of the downlights, fixing it in a position to give suitable clearance away from the joist. I then make a pilot hole where the centre of the downlight is going to be and then stick a wire from a coat-hanger into the hole pointing it in four directions to make sure the joist is far enough away. |
