When a Hatboro homeowner noticed dark vertical streaks running down their white gutters, they assumed the gutters were wearing out. They were not. Those black stripes are a cosmetic buildup called "tiger striping," and Regent Wash lifted every trace of it in a single visit.
What causes those black streaks on gutters?
Tiger striping forms when rainwater carries airborne dirt, pollen, and oxidized aluminum down the face of the gutter. Ordinary pressure washing will not lift it, and scrubbing by hand rarely reaches the full run. Gutter brightening uses a specialized, surfactant-based cleanser that breaks the bond between the stain and the metal so it rinses away clean.
Our soft, no-damage process
- We hand-apply a professional brightening solution across the gutter face.
- We let it dwell so it lifts the oxidation without aggressive pressure.
- We rinse from the top down for an even, streak-free result.
- We protect your siding and landscaping throughout.
The result is gutters that look freshly installed, with no ladders or guesswork required on your part.

What Tiger Stripes Really Are
Rain runs over the front edge of your gutters. It carries dirt and soot from the roof. When the water dries, a thin line of dirt stays behind.
The sun bakes that line onto the paint. After a few years, you get rows of black stripes.
They are stuck on. That is why a hose, and even a house wash, slides right past them.
Why White Gutters Show It Most
Black stripes stand out on white gutters. On a dark gutter, you might not see them for years.
That is why white homes show stripes so clearly from the street.
How To Check Your Own Gutters
- Look at them from the curb, in the morning light.
- Check the downspouts too. They streak the same way.
- If you can reach a spot from the ground, wipe it with a wet rag. Dirt comes off. Stripes stay.
- Rub the gutter with a finger. White chalk means the paint is oxidizing.
- Take a photo and text it to us. We can tell you what it is.
Why It Is Its Own Service
Brightening is slow. Each part of the gutter gets the cleaner, then a little time, then a scrub by hand, then a rinse.
It is done from a ladder, along the whole length of the gutter. That takes longer than a house wash, which is why it is priced on its own.
The good news is that it can be done on the same day as a house wash.
Oxidation On Siding
Gutters are not the only thing that goes chalky. Old aluminum siding does it too, and so does some vinyl.
A bright blue house can fade to a pale, dusty blue. A white one can turn gray.
We remove that chalk by hand, one section at a time. Here is a wall in Drexel Hill, PA that we photographed in the middle of the job.
The top still has the chalk. The bottom is done. The homeowner wrote that the siding came very close to its original color.
What Brightening Can And Cannot Do
Most gutters come back bright and clean. Very old gutters are different.
If the paint is worn thin, they will look much better, but not new. If a gutter is dented or the paint is peeling, cleaning will not fix that.
We look first, and we tell you what to expect before we start.
How Long It Lasts
Stripes take years to build up, so bright gutters stay bright for a long time.
Rain still runs over the edge, so a little dirt comes back over time. Booking brightening with a house wash keeps the whole house clean together.
A Few Quick Answers
Is this gutter cleaning? No. Gutter cleaning takes leaves out of the inside. Brightening cleans the outside, the part everyone sees.
Do I need to be home? No. We just need to reach the gutters and use an outdoor spigot.
Can you do the downspouts and trim? Yes. They usually have the same stripes and chalk, and they are done on the same visit.
Will it hurt my paint? No. The cleaner is made for painted gutters, and we scrub by hand, not with a strong spray.
How much does it cost? It depends on how long the gutters are, how tall the house is and how bad the stripes are. Quotes are free and come back in 24 hours.
Why Stripes Line Up
Stripes form where water spills over the gutter in the same spots, again and again. That is why they look like a row of lines.
Spots where the gutter dips a little get the most water, so they often have the darkest stripes.
Downspouts Need Care Too
Downspouts run down the side of the house, right where people walk by. They get stripes and chalk just like gutters.
We clean them from top to bottom on the same visit.
Before We Come
- Park cars away from the house.
- Close the windows.
- Move anything fragile away from the walls.
- Bring pets inside.
What You Will Notice After
The first thing most people notice is the roofline. It looks sharper and brighter from the street.
The second thing is that the rest of the house suddenly looks like it could use a wash. That is normal. It is also why we offer both.
When To Book It
Gutters can be brightened any time the weather is mild and dry. Spring, with the house wash, is a good time. So is fall, after the leaves are out of the gutters.
Either way, the stripes will be gone for a long time.
Hatboro And Closer To Home
This job was in Hatboro, north of our usual area. Most of our work is in Delaware County and on the Main Line, including homes in Havertown and Drexel Hill with the same kind of stripes.
Is It Safe To Do It Yourself?
Gutter work means ladders, cleaner and a lot of reaching. It is easy to scratch the paint or to slip. Gutters are high, and falls are serious.
If you want to try, work from a steady ladder with someone holding it, and never use a strong spray on the gutter. Or let us do it, and watch from the lawn.
What About The Rest Of The House?
Bright gutters on a green house look a little odd. That is why a house wash on the same visit makes sense.
The walls get a soft wash, the gutters get brightened, and the whole house comes out clean at once. It also costs less than two separate trips.
More Photos From Hatboro
We came back to this home for the gutters in July. We took this pair a few minutes apart. The second photo was taken partway through: bright on one side, still striped on the other.
