What size gutter does GutterBrush fit?

This trial pack is designed for standard 5-inch gutters and uses a 4.25-inch diameter brush. GutterBrush fits K-style, half-round, and fascia gutters made from any material — aluminum, PVC, copper, or steel. For larger 6-inch gutters, see our oversize 5.25" brush.

How is GutterBrush different from mesh gutter guards?

Unlike mesh gutter guards or micro-mesh covers that sit on top of the gutter and can clog on the surface, GutterBrush sits inside the gutter. Debris lands on top of the bristles and blows or washes away, while water flows through to the downspout. No surface clogging, no hidden debris buildup.

Do I need a professional to install this gutter guard?

No. GutterBrush is one of the only true DIY gutter guard options on the market. There are no tools, no screws, no hangers, and no cutting required. You simply slide the brushes into your gutter from end to end. Most homeowners complete a 15-foot section in under 10 minutes.

How long do GutterBrush gutter guards last?

GutterBrush is built with UV-protected polypropylene bristles and a galvanized steel core, rated for 15+ years of performance. Every brush comes with a 10-year product warranty — longer than most foam or plastic gutter guard alternatives.

Will GutterBrush work in areas with heavy pine needles or seed pods?

Yes. GutterBrush performs well across a wide range of debris types — leaves, pine needles, helicopters (maple seeds), and roof grit. The bristles hold debris on the surface until wind or rain clears it, rather than letting it pack inside the gutter.
