Waterfall gutter guard
Caulking a rain gutter at the seams is necessary to avoid rust and water dripping. If you choose to skip this task you will face a lot of problems.
The rain water and melted ice flow through the gutter and down to the downspout and are redirected from the house foundation.
In the place where two gutter sections meet there is a seam and also where the downspout connects to the gutter. If you want to match the gutter color with the caulk color you can choose clear caulk or you can go for white silicone caulk. Or you can just paint the caulk after. You shouldn’t buy cheap caulking. The caulking you buy must have a guarantee on it that is also for water use.
Cut the tip of the caulk at an angle, put the caulk tube into a caulk gun and apply the caulk steadily. You can smooth the caulk into a strip with your finger. If you apply the caulk well the job will last for a long period.
