Inside and outside are two different jobs
Almost every complaint we hear about a previous gutter clean comes down to this confusion. The customer wanted the gutters to look clean; the company cleared the inside and left.
**Clearing the inside** is drainage. Leaves, shingle grit and pine needles build into a dam, water backs up over the lip, and it runs down the fascia and behind the boards. In Jacksonville that means rotten fascia, wet soffits, and water dumping next to the foundation instead of away from it.
**Brightening the outside** is cosmetic, and it is a chemistry problem. Those black vertical stripes are not dirt. They are a bonded film of carbon, roof grit and oxidised aluminium, deposited by rainwater running over the lip and dried on by sun. Pressure washing does nothing to them — you can blast an aluminium gutter until you dent it and the stripes stay exactly where they are.
- Interior clearing protects the building; exterior brightening changes how the house looks
- A quote for gutter cleaning that does not mention striping almost certainly excludes it
- Brightening needs a dedicated surfactant-based gutter cleaner applied, agitated and rinsed
- It is normally done alongside a house wash, since the wall gets rinsed anyway
What tiger striping actually is
The name comes from the pattern: evenly spaced dark vertical bands down the face of a light-coloured gutter, following where water sheets over the front lip.
The mechanism is straightforward once you know it. Rainwater picks up carbon from vehicle exhaust and airborne pollution, plus fine grit washed off the shingles. As it runs over the gutter lip, surface tension holds a thin film against the face. The sun dries it there. Repeat that a few hundred times and the residue bonds to the factory finish, which is itself oxidising in the UV.
That is why it needs a chemical rather than force — you are dissolving a bonded film, not washing off dirt. A proper gutter brightener uses surfactants and mild acids to break the bond, and it is applied by hand, given a few minutes, agitated with a soft brush and rinsed.

How often Jacksonville gutters need clearing
Tree cover decides this, and in this city that varies enormously street to street.
Under mature live oak — Mandarin, Riverside, Avondale, San Marco, older Julington Creek — twice a year is genuinely necessary. Oaks drop leaves, catkins and acorns across multiple seasons rather than one autumn, and the debris is fine enough to pack into a dense mat that water cannot pass.
In open, newer subdivisions with young trees, such as much of Nocatee and RiverTown, once a year is plenty and some homes stretch beyond that.
One local specific worth knowing: pine needles are the worst thing for gutter guards. They thread through mesh and micro-mesh guards and build a mat on top that sheds water straight over the edge, which defeats the point. If you are in pine country toward Yulee and Nassau County and you have guards, they still need checking.
What we tell you if we find it
Being on a ladder at the roof edge twice a year makes us the people most likely to spot a problem early, and we would rather tell you than quietly move on.
- Rotten or soft fascia behind the gutter, usually from a long-standing overflow
- Gutters pitched wrong or sagging between hangers, so water pools instead of running
- Loose or pulled spikes and hangers that will fail in the next storm
- Separated or leaking seams and end caps
- Shingle granule loss visible in the gutter — often the first sign a roof is ageing
- Downspouts discharging against the foundation instead of away from it
What's included in every job
No line items appear on the invoice that weren't on the quote. Everything below is part of the price:
- All debris removed from inside the gutter runs by hand
- Every downspout flushed and tested to free flow
- Debris bagged and taken away, not left in your beds
- Gutter hangers, spikes and seams checked while we work
- Roof valleys cleared where they feed the gutter
- Photos of anything we find that needs a roofer
Brightening the outside faces is a separate chemical job, priced per linear foot. Read more in our Jacksonville pricing guide, or see what to ask before hiring anyone.
Expert tips from our crew
Things worth knowing whether or not you hire anyone. Several of these will save you money, and a couple of them will save you from a repair bill.
Clear before hurricane season, not after
A blocked gutter in a heavy storm dumps water straight down the wall and against the foundation. Late May is the right time in Jacksonville — before the season, after the oak drop has finished.
Look at the fascia, not the gutter
Dark streaks or peeling paint on the board behind the gutter mean it has been overflowing for a while. That is a repair conversation, and it gets more expensive every season you leave it.
Gutter guards are not a solution to pine needles
Needles thread into mesh and build a mat on top that sheds water over the edge. If you are in pine country you still need the guards checked, whatever the installer told you.
Check where the downspouts actually discharge
Plenty dump straight against the foundation. An extension costs very little and moves thousands of gallons a year away from your slab.
