Gutters are often most vulnerable at the seams where sections meet, leading to separations and leaks. Many seams can be repaired, but you may want to consider choosing seamless gutters.

Larger cracks can be easy to spot on clear days, but smaller cracks may only be obvious when the rain arrives. Individual cracks may be repaired, but widespread should be replaced.

If your building’s siding or paint is peeling or bubbling, you may have a gutter in disrepair.

An improperly working gutter can lead to wood rot. Check your exterior wood trim (door jambs, window sills, fascia, soffits, bargeboards) for signs of water damage.

If your downspout is too close to your structure, moisture will accumulate near the foundation and can eventually lead to mildew problems.
