5 inch or 6 inch gutters?

5-inch is standard for most homes. 6-inch handles more water and is recommended for large roof areas, steep pitches, or heavy rainfall regions.

How often should gutters be cleaned?

Twice per year minimum - spring and fall. More often if you have overhanging trees. Gutter guards reduce but do not eliminate maintenance.

Seamless or sectional gutters?

Seamless is preferred because it eliminates joint leaks. It requires professional installation with a forming machine on site.
