Harsh weather and the sun can cause the caulking on your chimney to deteriorate over time. When this happens, it will start letting water in through cracks, the flue, and areas that have flashing where your chimney and roof meet. New caulk is necessary to prevent water from seeping inside your house. Here's how to replace the caulking yourself.
Since your chimney can be the highest spot on your home, you need to take proper safety measures when working on it. When getting onto the roof, the ladder needs to be correctly propped against your home on a solid surface, with it being 1 foot away from the wall for every 3 feet of elevation. The ladder should extend 3 feet higher than your roof's edge, which will give you added stability for when you climb off the ladder and onto your roof.
For roofs that have deep slants, install several toe boards to give yourself additional support.
Remove The Old Caulking
The primary tools that you need are a small putty knife or utility knife for removing loose caulk that is around your flue and flashing. If you're having problems removing the caulk in some areas, the utility knife works great for digging underneath the caulk to separate it from the stone and brick. This should get rid of the majority of the old caulk.
If you have remnants of old caulk that remain, these should be removed as well so that the new caulk will form a great seal. Try using a brush with steel bristles for scrubbing away the remnants, and a soft paint brush for removing any dust that remains.
Applying The New Caulk
You cannot use the same caulk on your chimney that you would use inside your home for interior finishing. Your local home improvement store will have exterior weatherproof caulk that is ideal for your chimney.
Place the tube of caulk in your caulking gun, then cut the plastic tip at a 45 degree angle. This will help direct the caulk downward and smooth it out as you apply it. The caulk should be applied in a continuous line to ensure that there are no gaps in it. If you are caulking an object such as an exhaust pipe, you should continue the bead of caulk until it overlaps the starting point to ensure a good seal.

This year, things were a little different over the winter. In winters past, I had to park my car in the driveway because my husband had our two-car garage filled with all of his man-toys. Each morning, I would have to struggle to break the ice and shovel the snow to get to my car, so last fall, I had enough and hired a contractor to build a garage just for me. My husband and I weren't sure about adding another structure to the property, but it is the best thing that we have done since we bought the house. Learn how my contractor helped my family with the design of the garage that he built.
