Gutters full of leaves, dirt, and sludge are a common problem -- but pressure washing them is not as simple as pointing a gun at the gutter and pulling the trigger. Done wrong, you'll blow debris into your downspouts, damage gutter seams, or take a dangerous fall. Here's how to do it safely.

The Quick Answer

Professional gutter pressure washing costs $191-$529 for most homes in 2026, or $0.50-$1.50 per linear foot. Here's a fast comparison:

DIY equipment cost (one-time): $50-$200 for tools and a gutter wand attachment
Professional (single-story home): $100-$200
Professional (two-story home): $200-$400
Professional (large or complex roofline): $400-$529+

If you're comfortable on a ladder and your home is one story, DIY is reasonable. For anything higher, hire a pro. Ladder falls result in $17,000-$41,000 in medical costs on average.

DIY Gutter Pressure Washing: What You Need

The key tool is a gutter wand -- a curved telescoping attachment that hooks over the gutter edge so you can wash from the ground without leaning a ladder into the gutter trough.

Full equipment list:

Pressure washer (1,500-2,500 PSI is enough for gutters)
Gutter cleaning wand or telescoping attachment ($20-$60 at any hardware store)
25 or 40-degree nozzle -- never use a 0-degree or turbo nozzle on gutters
Safety glasses and waterproof clothing (debris flies in all directions)
Gloves for clearing downspout clogs by hand

Step-by-Step: How to Pressure Wash Gutters

Start near the downspout. Work toward it, not away from it. This pushes debris toward the exit point instead of packing it in tighter.
Flush section by section. Move the wand slowly from one end to the other, sweeping debris toward the downspout opening. Work in 10-foot passes.
Flush the downspout. Insert the wand directly into the top of the downspout and blast water down. A clog will cause water to back up -- flush several times until it runs free. If it stays clogged, you may need to clear it by hand from below.
Check for leaks. While water is flowing, walk the roofline and look for drips at seams, end caps, or where downspouts connect. These are cheap repairs now and expensive water damage later.
Rinse the exterior. Run a light spray along the outside of the gutters to remove algae streaks and oxidation staining.

What PSI to Use on Gutters

This is where most people go wrong. Gutters are thin aluminum or vinyl -- not concrete. Too much pressure bends the trough, separates seams, and knocks hangers loose from the fascia.

Aluminum gutters: 1,500-2,000 PSI max
Vinyl gutters: 1,200-1,500 PSI max
Steel gutters: Up to 2,500 PSI is acceptable

Use a 25 or 40-degree nozzle and keep the wand moving at all times. Holding it in one spot at high pressure will blow out seams and end caps.

When to Call a Professional

Here's the straight answer: most homeowners should hire out. Here's why:

Two-story or higher homes: Ladders at that height carry serious fall risk. Professionals use stabilized ladders, harness systems, and standoff mounts.
Heavy clogs or compacted debris: Consumer pressure washers max out at 1,800-2,400 PSI. Professional units run 3,000-4,000 PSI and push through packed leaf matter that a homeowner's machine won't budge.
Complex rooflines: Multi-gabled roofs require constant repositioning -- more repositioning means more fall risk and more time.
Time: A professional cleans a typical home in 1-2 hours. DIY on an unfamiliar ladder takes 3-5 hours.

DIY vs. Professional: Side-by-Side

DIY upfront cost: $50-$200 in equipment (reusable), plus 3-5 hours of your time per cleaning
Professional cost: $191-$529 per visit, done in under 2 hours
Professional advantage: Commercial-grade equipment, trained to spot damage while on-site, no fall risk to you
DIY advantage: Free after the initial equipment purchase, do it on your own schedule

Most homeowners who DIY their gutters once decide it's worth hiring out. The height, the mess, and the time don't make it an easy afternoon project.

How Contractors Can Add This Service

Gutter pressure washing is a natural upsell for any pressure washing contractor. When you're already on-site for a house wash or driveway job, spotting clogged gutters is easy -- and offering to clear them adds $100-$300 to the ticket with no extra drive time.

Equipment cost is low (a gutter wand attachment costs under $60), and the margin is good because you're already there. The most profitable contractors bundle gutter cleaning with every exterior house wash quote by default.

Bottom Line

Pressure washing gutters is manageable as a DIY project on single-story homes with a gutter wand and the right PSI setting. For two-story homes, the math almost always favors hiring a professional -- you're paying $200-$400 to avoid the average $17,000-$41,000 medical bill from a ladder fall.
