Gutter Whitening & Brightening That Erases Black Tiger Stripes
Those black vertical streaks on your gutters are called tiger stripes: oxidation and road grime bonded to the aluminum. Rain won't wash them off and neither will a pressure washer. Gutter brightening uses a specialty detergent that dissolves the oxidation and restores gutters to bright white. It's the cheapest, fastest curb appeal upgrade on your whole exterior.
Why Regular Washing Doesn't Work on Gutters
Tiger striping is electrostatically bonded to the painted aluminum. It laughs at soap and pressure. Our brightening solution breaks that bond chemically, then we hand-detail stubborn sections. Most customers can't believe the gutters aren't new.
What We Do
- Exterior gutter face brightening
- Downspout cleaning and brightening

Answers
Frequently Asked Questions
Is gutter brightening the same as gutter cleaning?
No. Cleaning clears leaves from inside; brightening restores the outside faces. We focus on the exterior, and can quote interior clean-outs alongside.
Why won't pressure washing remove tiger stripes?
The stripes are bonded oxidation, not surface dirt. Pressure alone either doesn't touch them or strips paint trying.
How much does gutter brightening cost?
Typically $100-$250 as a standalone, less bundled with a house wash. Most customers bundle.
Will it damage the paint on my gutters?
No. The detergent targets oxidation and grime, not sound paint. We test a small section first on older gutters.
How long do results last?
Usually 1-2 years before striping starts to rebuild, longer if gutters are brightened regularly.
