My chimney flue is 17" standard mason size. It is mortared into a brick chimney that is flush on top. It measures 28x28 inches. Do I need an insert type for the inside flue or a 28x28 to fit over the whole chimney top?

Can you tell me how to install a stainless steel mesh on a existing chimney cap?

Answer:If you are installing a pre made spark arrestor screen, it can generally be installed by removing the lid of the chimney cap, then sliding the mesh into place. It is usually designed to expand and hold itself in position. If you using non formed mesh, you will need to do the same, but the mesh will need to be secured to the underside of the cap by using "L" brackets, along with machine screws and nuts.
