We know how this goes.
The house just got washed. The siding looks great. You stand in the yard and feel proud of your house, and a little proud of yourself.
Then you look up.
The gutters still have black stripes. Long ones. Like a zebra, but sad.
So you decide that nobody looks up.
Everybody looks up.
Here is the thing. Those stripes are not dirt. That is why the wash did not touch them.
What the black stripes are
Rain runs over the front of your gutters. It brings dirt and soot down from the roof. The water dries, but the dirt stays.
Then the sun bakes it on. Over time, it sticks to the paint like tape. People call these tiger stripes.
Why a house wash leaves them behind
House wash soap is made to kill the green stuff on siding. The stripes are not alive. So the soap slides right past them, and they stay put.
How we get them off
- We put a gutter cleaner on the front of each gutter.
- We let it sit, so it can loosen the stripes.
- We scrub by hand, one part at a time.
- We rinse it all off, from the top down.
It is slow work, done from a ladder. That is why gutter brightening is its own job and not part of a house wash.
What it can fix, and what it can't
Most gutters come back bright and white. Very old ones are not the same. If the paint is worn thin, they will look a lot better, but not brand new. We tell you which kind you have before we start.
How to tell stripes from dirt
Here is a quick test. Wet a rag. Wipe one small spot on the front of a gutter you can reach from the ground.
If the black comes off easy, it is just dirt. A rinse can handle that.
If the black stays put, it is a stripe. It is stuck to the paint. That is a job for gutter brightening.
Please do not climb a wobbly ladder for this test. No gutter is worth a fall.
What the white chalk is
Now rub the gutter with your finger. Does it come away white, like chalk from a chalkboard?
That is called oxidation. The paint is slowly breaking down in the sun. It makes the gutter look dull and gray, even when it is clean.
The same thing can happen to siding. A blue house can fade to a pale, dusty blue. A white house can turn a flat, tired gray.
We take that chalk off by hand, too. It is the same kind of work as the stripes.
Why you should not blast them
Some people try to fix stripes with a strong pressure washer. It seems like a great idea for about ten seconds.
A hard spray can scratch the paint. It can dent a thin gutter. It can push water up under the edge of the roof.
And the stripes? They are still there. Now they have scratches to keep them company.
How long bright gutters last
Stripes take years to build up. So once they are gone, they stay gone for a long time.
Rain still runs over the edge, though. Slowly, a little dirt comes back. That is why it makes sense to book brightening with a house wash, so the whole house stays clean together.
Questions we hear a lot
- Do I need to be home? No. We just need to reach the gutters and use an outdoor spigot.
- Is it the same as gutter cleaning? No. Gutter cleaning takes the leaves out of the inside. We clean the outside, the part people see.
- Can you do the downspouts? Yes. They get stripes too, and we do them on the same visit.
- Will it look brand new? Most gutters come back bright. Very old paint looks much better, but not new. We tell you first.
- How long does it take? Most homes are done in a few hours.
- Do you clean the inside of the gutters? No. We clean the outside. If they are full of leaves, have them emptied first.
How a stripe is born
Here is the life of one stripe, start to finish.
- Year one: a little rain runs over the gutter. Nobody notices.
- Year two: a faint gray line shows up. Still, nobody notices.
- Year three: the line gets darker. The neighbor notices. The neighbor says nothing.
- Year five: there are twenty lines. Everyone notices.
Stripes are slow. That is how they sneak up on people.
Colored gutters get them too
Not all gutters are white. Brown, black and tan gutters get stripes too. They are just harder to see.
Colored gutters can also fade and go chalky in the sun. Brightening helps them the same way.
Why we rinse from the top down
Dirty water runs down. So we always rinse from the top of the house to the bottom.
That way, nothing dirty drips onto a part we already cleaned. It sounds simple. It is also the step people skip.
Before we come
- Park cars away from the house.
- Close the windows.
- Move anything fragile away from the walls.
- Bring pets inside.
Stripes and selling a house
When a house goes up for sale, buyers look at the outside first. Striped gutters make a house look older than it is.
Brightening before the listing photos is a small job that makes a big first impression. Tell us the photo date, and we will plan around it.
Brighter gutters, brighter house
Gutters run along the top of the whole house. So when they are striped, the whole house looks tired, even if the siding is clean.
When the gutters are bright, the roofline looks sharp. It is a small part of the house that changes how all of it looks.
What about the trim?
The boards behind the gutters, called fascia, can get the same chalk and stains. So can the soffit, the flat part under the roof edge.
We clean those on the same visit, so the whole top edge of the house matches.
What you can do this week
- Stand at the curb and look at your gutters in the morning light.
- Do the wet rag test on one spot you can reach safely.
- Check your downspouts and the trim near the roof.
- Snap a photo and text it to us. We can tell you what it is.
A real one from Hatboro
The photo at the top is from a home in Hatboro, PA. We took it while we were still working. The left side is done. The right side is not done yet. It is the same gutter, on the same day.
Another real one, from Drexel Hill
In September, we worked on an older stone house in Drexel Hill, PA. The gutters had stripes. The blue siding up top had gone chalky.
We took this photo in the middle of the job. The top part still has the chalk. The bottom part is done. It is the same wall, on the same day.
The homeowner wrote that the siding came very close to its original color. Close is the honest word, and we like it.
So yes, people look up.
Now you can let them.
