Gutter cleaning
Brightening cleans the outside. A gutter cleaning clears the inside, and we do it first so the rinse stays clean.
Gutter cleaning detailsGutter brightening is the cleaning of the outside face of your gutters to remove tiger stripes, oxidation, and black 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 runTiger 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 asphalt particles from the shingles. 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 |
Four things work against a gutter finish here, and they stack.
If your roof has black streaks, the gutters under it will keep streaking until the roof is cleaned. See our roof pressure washing page for how we handle that.
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.
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. The cleaner is gutter-safe, and plants still get the same care as on a roof wash.
A small patch on a low, out-of-sight section tells us how the finish reacts. We can see 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.

Walk to the street and look at the roofline. These show up from there.
None of these affect how the gutter drains. They affect how the house looks, and they are easiest to fix while you are already having the trough cleaned.
The quote depends on how much gutter face there is and how stubborn the marks are.

Gutter cleaning detailsA blocked downspout sends water over the edge and streaks the face below it. We clear the pipe so the stain does not return.

They are called tiger stripes. Roof runoff carries dirt, pollen, and asphalt particles down the face of the gutter, and an oxidized finish grabs them. The result is vertical black streaks that rain alone will not wash off.
Gutter brightening is the cleaning of the outside face of the gutter to remove tiger stripes, oxidation, and surface stains. It does not touch the inside of the trough. Gutter cleaning handles the debris, and brightening handles the finish.
Mostly yes. People use both terms for the same job, which is cleaning oxidation and streaks off painted aluminum gutters. We call it brightening because the goal is to restore the original finish, and the finish is not always white.
Pressure alone usually cannot. The streaks are bonded to an oxidized layer, so they need a gutter-safe cleaner to release them. We apply the cleaner, work it with a soft brush where needed, and rinse at low pressure so the finish and the fascia stay intact.
It should not. We test a small hidden spot first, use a cleaner matched to the finish, and keep the rinse gentle. Paint that is already peeling or flaking can come off with the streaks, and the test spot tells us before we start.
Often, but not always to like-new. Some finishes are chalked or worn through, and no cleaner restores paint that is gone. The test spot shows us how the gutter will respond, and we tell you what to expect before we do the whole house.
No. Rust is the metal itself breaking down, usually at a seam, a fastener, or on steel gutters. Brightening cleans the finish. We point out rust when we see it so you can decide on a repair.
It depends on how much runoff and shade the gutters get. Streaks return faster on shaded sides, under trees, and below a streaked roof. Keeping the trough clear and washing the roof slows them down.
After. We clear the trough first so the rinse water has somewhere to go and does not carry debris down the face. A gutter cleaning visit with brightening added is the usual order.
Vinyl and painted aluminum respond well to the right cleaner. Steel and copper need different chemistry, so we ask what you have, check the finish, and tell you what we recommend before we start. Call with the gutter material when you book.
Tiger stripes build over time, so a recently washed roof can sit above old streaks. Fresh runoff keeps feeding them if the roof has algae, which is why roof pressure washing and brightening often go together.
