IF GUTTERS ARE NOT CLEANED
The overflow of water, if the gutters are not cleaned will fall along the foundation of the building. Excess water can soften the soil under and around it which will lead to foundation cracks.
The debris in gutters, especially when moist, is a very attractive habitat for insects. These insects will be attracted to the inside of the house when the weather changes, and so can lead to insect infestation within the home.
If gutters are clogged, water will overflow onto the building and also will be trapped in the gutter after rain. This moisture will cause rot in wood fascia and soffit boards.
The water that falls from obstructed gutters can kill plants and grass living below. The water will then wash away exposed topsoil and sand. If left alone long enough, this erosion can etch away the landscape under the clogged gutter and leave a ditch.
