Dented, cracks, holes or rust spots.

A few of these can be repaired using some good sealant and some flashing. However, if you see multiple sections where this is apparent, you may want to just replace the entire gutter system.

Screws below or in the gutter.

Occasionally, nails or screws that support the gutter to the fascia can work themselves loose. Replacing them is not difficult. However, this may be a sign that your fascia may be rotting as well.

Peeling exterior paint.

If your gutters have pulled away from the roof or have been leaking, water can seep down to your siding or trim. Paint damage means this has been happening for a while and your gutters should be repaired or replaced.

Water constantly pouring against your foundation can sometimes find its way through into your basement. While this may mean repair to your foundation, you will want to re-direct the water if possible.


During the tornado in September, a tree landed between our house and garage. Our roof was damaged and our rain gutters took a beating. A1 came out and had the job finished before the last of the branches were hauled away. We couldn’t be happier with their work.
