The gutters and downspouts on your home are intended to channel rainwater away from your home and its foundation. When they're blocked and not functioning properly they can lead to the gutters coming loose, wood rot and mildew, staining of painted surfaces, and even worse, foundation issues or water penetration into the interior of the home.
Most experts recommend cleaning the gutters at least once a year. More often might be necessary depending on the proximity of leaves and other debris that could collect.
If this is a task that you feel comfortable about tackling yourself, there are few things to consider. If the debris is dry, it will be easier to clean the gutters. Safety is important, and precautions should be taken such as using a sturdy ladder and possibly, having someone hold it while you're on the ladder.
Other useful tools will be a five-gallon plastic bucket to hook on the ladder to hold the debris; work gloves to protect your hands from sharp edges of the gutters; a trowel or scoop and a garden hose with a nozzle.
Start by placing the ladder near a downspout for the section of gutter to be cleaned.
Remove large debris and put it into the empty bucket. Work away from the downspout toward the other end.
When you're at the end of the gutter, using the water hose and nozzle, spray out the gutter so it will drain to the downspout.
If the water doesn't drain easily, the downspout could be blocked. Accessing the spout from the bottom with either the hose with nozzle or a plumber's snake, try to dislodge the blockage.
Reattach or tighten any pieces that were removed or loosened while working on the downspout.
Flush the gutters a final time, working from the opposite end, as before, toward the downspout.
