If you're replacing gutters, the first choice is seamless or sectional. Here's how they differ.

Sectional gutters

Sold in 10- or 20-foot pieces and joined with connectors and sealant. They're the DIY option at big-box stores. Every joint is a spot that can leak as the sealant ages and the metal expands and contracts through Kentucky's hot summers and freezing winters.

Seamless gutters

Formed on-site from a continuous coil of aluminum with a gutter machine, cut to the exact length of each roof run. The only joints are at corners and downspouts, so there are far fewer places to leak.

Comparing them

  • Leaks: seamless has far fewer joints, so fewer leaks
  • Look: seamless runs look cleaner from the street
  • Install: sectional can be DIY; seamless needs a pro with a gutter machine
  • Upfront cost: sectional is cheaper; seamless usually costs less over its life

Our recommendation

For most homes, seamless aluminum is the better long-term value, and it's the best time to add gutter guards. Call for a free estimate.
