See ZIP 33301Gutter brightening is the cleaning of the outside face of your gutters to remove tiger stripes, oxidation, and dark streaks. Clearing the trough does not touch those marks. Fast Pro washes the face of each run with a gutter-safe cleaner and a low-pressure rinse, so the gutters match the rest of your roofline.

Photos of every runSun and salt air leave Fort Lauderdale gutters streaked faster than a typical inland Florida city, especially close to the canals and the coast.
Painted gutters oxidize under Fort Lauderdale's sun the same way they do anywhere in South Florida, but salt air changes the timeline. A canal-front gutter near Las Olas Isles or Coral Ridge, exposed to both sun and the salt carried off the water, often chalks and streaks faster than an identical gutter a few miles inland in a neighborhood like Victoria Park.
We test a hidden spot before we start, since the finish on a century-old Fort Lauderdale property has had far longer to age than one on newer construction. Runoff from an algae-prone tile roof adds to the streaking on the gutter face below it, and on canal-front homes, salt deposits can leave a hazy film on top of the usual dirt.
Near Port Everglades and the busier canal corridors, boat traffic and marine industry add a bit more airborne grime than a quiet residential canal sees, which is worth knowing before comparing notes with a neighbor on a different waterway.
We test the downspout side of the run first, since it usually sees less direct sun and salt spray than the open face, and shows us closer to the real baseline color before the coastal exposure is factored in. On a home facing a busy canal, that baseline often differs more from an inland Fort Lauderdale street than the short distance would suggest. A finish that's gone a few years without attention on a busy canal often shows the difference most clearly right where the gutter turns a corner, since that's where runoff and salt spray tend to collect rather than wash straight off.
Tiger stripes look like dirt. They behave like a stain, because they are bonded to the finish.
Painted aluminum gutters slowly oxidize in the sun, which leaves a thin chalky layer on the surface. Rain running off the roof carries dust, pollen, and particles from the roofing. That mix sticks to the chalky layer and dries into vertical streaks. A garden hose will not shift them, and neither will a pressure washer, because the problem sits in the surface and not on top of it.
| Mark | Looks like | Usually caused by | What we do |
|---|---|---|---|
| Tiger stripes | Black or gray vertical streaks | Oxidized finish holding roof runoff and pollen | Apply cleaner, work it in, rinse at low pressure |
| Chalky oxidation | White or gray powder that rubs off on your hand | Sun and age breaking down the paint surface | Clean and brighten, then check the finish underneath |
| Mildew and algae spots | Green or black dots on shaded sections | Damp, shaded gutter faces under trees | Treat and rinse the affected sections |
| Overflow stains | Brown streaks below a clogged downspout or corner | Water spilling over a blocked gutter | Wash off, then fix the cause with a gutter cleaning |
| Rust | Orange or brown spots at seams and fasteners | The metal breaking down | Not removable by brightening, we flag it for repair |
One handles what is inside the gutter, and the other handles what shows on the outside.
| Gutter cleaning | Gutter brightening | |
|---|---|---|
| Works on | The inside of the trough | The outside face |
| Removes | Debris, pollen paste, grit | Tiger stripes, oxidation, surface stains |
| Helps with | Water flow and overflow | How the house looks from the street |
| Done | Two to four times a year | When streaks show, often with a cleaning |
Start with the gutter cleaning if the trough has not been done this year.
Several things work against a gutter finish, and they stack.
If your roof has dark streaks, the gutters under it will keep streaking until the roof is cleaned. See our roof pressure washing page.
We work in sections so the cleaner never dries on the finish.
Debris comes out by hand before any cleaner goes on. A full trough sends dirty water down the face of the gutter and undoes the work.
Shrubs and flower beds under the gutter line get wet down and covered.
A small patch on a low, out-of-sight section tells us how the finish reacts, and whether the paint is sound, before we do the rest.
The cleaner goes on one section at a time and sits just long enough to release the streaks.
Stubborn tiger stripes get a soft brush or pad. We do not scrub hard on the finish, because that scratches it.
The face and the underside of the gutter get a gentle rinse, then the plants and the ground below.
You get before and after photos of each run, and a plain note on any section that would not fully clean.

Heavily oxidized gutters may brighten but not return to like-new. The test spot tells us first.

It depends on the roof size, material, and how far gone the staining is. Canal-front homes with salt exposure sometimes need more attention than an inland roof of the same size. Call with your address and we quote by phone.
It depends on the feet of gutter, the number of stories, and whether the home is canal-front or inland. Call with your address and we quote by phone.
Early May, before the wet season starts on May 15, matters most, with a second visit after hurricane season between October and December.
Yes. Salt air and boat traffic humidity speed up oxidation and algae growth compared to a drier, more inland property.
We cover the city end to end, from Las Olas Isles, Rio Vista, and Coral Ridge to Victoria Park, Colee Hammock, and the neighborhoods farther inland.
The city's April 2023 record rainfall showed how fast water moves through this area when drainage is blocked. We check that every downspout actually clears water, not just that the gutter looks empty.
Often, yes. That area sees the heaviest salt air and boat traffic in the city, which speeds up both gutter oxidation and roof algae growth.
Yes, and either neighborhood can be the first stop of the day. Call with your street and we'll find a time that works.
Often, yes. Salt air speeds up oxidation beyond what sun alone would cause on an inland property.
On busier canals and near Port Everglades, yes, a bit. Marine traffic adds airborne grime on top of the usual dirt and algae.
There's no hard line, but homes directly on the water or within a block or two of it typically show faster streaking than properties set back farther inland.
Corners and downspout outlets usually show it first, since that's where runoff and salt spray tend to pool rather than run straight off the face.
