Metal gutters and downspouts can amplify the sound of rain, especially when there are multiple corners, bends and water deflectors. If you hear pounding or rattling—particularly in second‑floor bedrooms—try one or more of these effective solutions.
1. Nylon Rope to Damp Noise
An easy way to reduce the noise is to insert a nylon rope into the downspout. Using gutter sealant, glue a rope of 3/8″ in diameter around the opening, and then secure it inside the elbows so that it conforms to the shape of the downspout.
2. Sponge or Shingle to Muffle the Sound
Another option is to place a square piece of sponge, shingle, or carpet at the bottom of the elbow to absorb the noise. Just make sure the spongy material doesn’t accidentally block the downspout, which could lead to much more serious problems than a noisy gutter.
3. Rain Chain as an Alternative
If the noise becomes truly unbearable, you can always use a rain chain instead. This way, rainwater will glide gently down the chain rather than falling noisily down the downspout.

Consult a Gutter Expert
In many cases, it can be difficult to identify the root cause of a problem and how to fix it. Consider contacting a gutter installer to find an expert who will be able to explain your options. In some cases, you may have to change the angle of the downspout or make other adjustments to remedy the situation.
Annoying noises may also be the result of broken or leaky gutters. An expert will be able to provide you with a permanent, hassle-free solution.
