Like-New Gutters. No Replacement Needed.
Gutter Brightening
Those dark vertical streaks running down the face of your gutters aren't going away with a garden hose or a pressure washer. They're chemically bonded to the surface. Gutter brightening removes them completely — and the results are dramatic.
Tiger striping is caused by oxidation of the aluminum combined with electrostatic bonding of dirt and debris from roof runoff. Regular pressure washing doesn't remove it because the staining is attached to the gutter surface, not just sitting on top.
Gutter brightening uses a specialized solution applied by hand that breaks down the oxidation and lifts the staining without scratching or damaging the gutter surface. It's one of the most dramatic visual improvements you can make to your home's exterior without replacing anything.
The Detail That Changes the Whole Picture
Gutters run the full perimeter of your roofline. When they're streaked and oxidized, they drag down the appearance of the entire exterior — even on a home that's otherwise well-maintained.
Brightening is often paired with gutter cleaning for a complete refresh. Clean inside, bright outside. It's a straightforward service with results that are hard to miss.

Common Questions
Why won't pressure washing remove the streaks on my gutters?
Tiger striping is caused by oxidation and electrostatic bonding — the staining is chemically attached to the gutter surface, not just sitting on top of it. Water pressure alone can't break that bond. Brightening uses a chemical solution specifically formulated to dissolve the oxidation without damaging the metal.
Will brightening damage my gutters?
No. The solutions we use are designed for aluminum and vinyl gutters and are applied by hand with soft cloths or applicators. There's no abrasive scrubbing involved. The process is gentler than it looks.
Should I get my gutters cleaned before brightening?
Yes, and we typically recommend doing both together. Cleaning removes the debris and buildup inside, brightening restores the exterior appearance. Doing them at the same time is the most efficient approach.
How long does gutter brightening last?
Results typically last one to three years depending on tree cover and how much debris runs off your roof. The oxidation will gradually return over time, but the process can be repeated as needed.
