See ZIP 33157Gutter 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.

Every brightening includes
Photos of every runCutler Bay's newer gutters streak less than older Miami-Dade hardware, but proximity to Biscayne Bay can speed up oxidation on homes closest to the water.
Painted gutters oxidize under Cutler Bay's sun the same way they do anywhere in Miami-Dade, but the newer average age of the hardware here, mostly installed since the town's 2005 incorporation, means the chalking is often lighter than what we'd see on decades-old gutters elsewhere in the county. What speeds it up in Cutler Bay is the bay itself: salt air near Black Point Marina and the waterfront accelerates oxidation beyond what a more inland Cutler Bay street would show.
We test a hidden spot before we start, since even a newer finish responds differently depending on how much salt exposure it's had. Runoff from an algae-prone tile roof adds to the streaking on the gutter face below it, the same as anywhere else.
On post-Andrew concrete-wall construction, the gutter mounting itself is usually sturdier than on older wood-frame homes, which gives us more room to work the cleaner in without worrying about the attachment point.
We test the downspout side of the run first, since it usually sees less direct sun than the open face and shows us closer to the real baseline color before salt air and runoff are factored in. On a home closest to Black Point Marina, that baseline often differs more from a more inland Cutler Bay street than you'd expect from such a short distance.
Concrete-wall homes from the post-Andrew rebuild often have gutters mounted with newer, sturdier hardware than older wood-frame construction, which means the brightening itself usually goes faster here even when the streaking looks just as heavy. A hidden test spot on the shaded side of the gutter, away from direct afternoon sun, usually gives the truest read on how much of the original finish is still there to recover.
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 feet of gutter, the number of stories, and how packed the runs are. Share your address with us and we'll quote the work over the phone.
The visit that counts most is early May, right before the wet season starts. A follow-up between October and December, after hurricane season has passed, handles the rest.
It raises the stakes on drainage. A blocked downspout on this low, flat ground backs up faster than it would on higher ground, so we check discharge points carefully.
Yes. Newer construction means younger hardware, not maintenance-free gutters. Palm fronds and roof grit still collect the same way.
We cover the town end to end, from Lakes by the Bay to the streets near Black Point Marina and the Saga Bay and Cutler Cay communities.
Salt air can speed up oxidation on gutters closest to the water, which is worth knowing if you're near Black Point Marina or the bay itself.
Somewhat. It's one of the town's older rebuilt neighborhoods, so the roofing and gutters there have had more years of wear than the newest subdivisions.
Yes, along with the rest of Cutler Bay. Tell us your community and street when you call.
Often, yes. Salt air near Black Point Marina and the waterfront speeds up oxidation compared to more inland streets.
It depends on sun exposure and proximity to the bay. Newer doesn't mean immune, especially on a west-facing or waterfront-adjacent run.
There's no hard line, but homes within a few blocks of Black Point Marina or the open water typically show faster oxidation than streets farther inland.
Often, yes. Sturdier, newer mounting hardware gives us more room to work the cleaner in without worrying about the attachment point the way we might on older wood-frame construction.
Call and tell us what the gutters look like and what they are made of. We quote by phone and find a day that works.
