A plugged or blocked chimney could cause the products of combustion to back up and filter through your home…and that is very dangerous to your health. So inspect your chimney each fall. It’s simple and only takes a few minutes of your time.
When cutting up small pieces for a project, an easier way to doublecheck for accuracy is to measure a number of the pieces at once. If you have four pieces which should be exactly 8 in. long, lay them end to end and measure. This multiplies small errors hard to detect on only one piece. For example, if the four pieces measure 32-1/8 in. instead of 32, then you know that each of the pieces is 1/32 in. too long.
