Step by step
Step 1 of 12
Check the weather, the helper, and the height
Do this on a calm dry day with someone else at home. Walk the perimeter first and decide which runs you can reach from a ladder on firm level ground, and which runs are two stories or near the power line — those go on the hire-it-out list right now. Lay the tarp under your first section.
Before the ladder goes up
- No wind, no rain, no wet ground
- Someone else is home and knows you are on a ladder
- Every run you plan to do is single story and reachable without leaning out
- You have identified the overhead service drop and will stay 10 ft from it
- Closed shoes with clean dry soles, gloves and glasses on
Step 2 of 12
Set the ladder correctly
Put the feet on firm level ground and set the angle by the 4 to 1 rule: the base goes out 1 ft for every 4 ft of height to the contact point. Extend it so at least 3 ft of ladder sticks up past the roof edge, and fit the standoff so the ladder bears on the fascia or the roof, never on the gutter. Check that both feet are flat and the ladder does not rock before you put weight on it.
Step 3 of 12
Find the service drop and mark the no-go zone
Stand back and trace the overhead wire from the pole to where it attaches to the house. Mark the ground with tape 10 ft either side of that point and treat everything inside it as off limits for you, the ladder, and the hose. If the gutter needs work in that zone, note it for the contractor and move on.
Step 4 of 12
Scoop the trough into the bucket
Hook the bucket to a rung, face the ladder, and scoop from the section right in front of you, working away from the downspout. Keep your belt buckle between the rails: when you can no longer reach comfortably, climb down and move the ladder. Empty the bucket onto the tarp when it gets heavy — not by dropping it.
Step 5 of 12
Flush the trough with the hose
Start at the end farthest from the downspout and run the hose toward it so the fine grit goes out with the water. Watch where the water sits: a puddle that does not drain marks a low spot or a sagging hanger. Never put a pressure washer in a gutter.
Step 6 of 12
Clear each downspout from the bottom
Push the hose up into the bottom of the downspout and run it — the clog usually breaks loose and washes out at your feet. If it will not clear, feed the hand auger up from the bottom and work it, or tap the length of the downspout with your palm to loosen a packed plug. Do not stop until water runs out the bottom at full flow.
Step 7 of 12
Re-secure loose hangers and spikes
Any place the gutter has pulled away from the fascia gets a new hidden hanger driven into solid wood, not back into the old stripped hole. Replace old spikes with screw-in hangers, and space them as the hanger maker specifies — commonly every 24 to 36 in. Push the gutter back up tight to the fascia before the screw bites.
Step 8 of 12
Fix the slope where water stands
The trough should fall toward the downspout; a common rule of thumb is about 1/4 in of fall for every 10 ft of run. Where you saw a puddle, loosen the two nearest hangers, lift that section slightly, and re-fasten. Re-flush and watch the water leave before you call it done.
Step 9 of 12
Seal the seams and end caps
Dry the inside of the trough and scrape the old failed sealant off the seam with a putty knife. Lay a continuous bead of gutter sealant over the joint from inside the trough and tool it flat with a gloved finger. Give it the cure time on the label before you run water over it.
Step 10 of 12
Send the water away from the house
Fit an extension or a splash block on every downspout that currently ends at the foundation, and aim it so water lands at least 4 ft from the wall — 6 ft is better on a flat lot. Point it downhill, not into a planter bed against the house. This is the cheapest waterproofing you will ever buy.
Step 11 of 12
Run the whole system once with a witness
Put the hose in the far end of each run at full flow and walk the outside of the house while it runs. You are looking for drips at seams, water running behind the gutter at the fascia, and overflow at any corner. Fix what shows and run it again.
Quality check
- Every reachable run scooped and flushed clean
- Every downspout runs full flow out the bottom
- No standing water left in any trough after flushing
- Loose hangers replaced into solid wood; gutter tight to the fascia
- Seams and end caps sealed and given the cure time on the label
- Every downspout discharges at least 4 ft from the wall
- Runs near the service drop or above one story written down for a contractor
Step 12 of 12
Clean up and set the next date
Fold the tarp with the debris inside and bag it for green waste, wipe and dry the ladder before it goes away, and photograph each finished run. Put two reminders in your phone: one in the fall after the leaves drop, one right before the first winter rain. In Los Angeles, October is the deadline that matters.
Common mistakes
- Leaning the ladder against the gutter. A gutter is a thin aluminum trough held by a few screws. Your weight on the ladder bends it, pops a hanger, or drops you. Use a standoff that rests on the fascia or the roof edge, or move the ladder to a rafter tail. Mistake #1 in this task.
- Reaching sideways instead of moving the ladder. Keep your belt buckle between the ladder rails. The moment your hip passes a rail, the ladder wants to walk sideways out from under you. Climb down and move it — twenty extra trips beat one fall.
- Working next to the service drop. The overhead line that feeds the house is not insulated where it lands, and an aluminum ladder or a wet hose is a perfect conductor. Stay at least 10 ft away from it with everything you are holding. That section of gutter is a pro job.
- Pressure-washing the gutters. A pressure washer blows the seams apart, drives water up under the roof edge, and throws sludge everywhere. Scoop the debris out by hand and rinse with a garden hose.
- Cleaning the trough and leaving the downspout plugged. A clean gutter that drains into a packed downspout still overflows in the first real rain. Every downspout gets tested with the hose until water runs freely out the bottom.
