With cooler temps and falling leaves, fall seems like the perfect time to refresh your home’s exterior. But if you’re tempted to grab a rented power washer and do it yourself, you may be doing more harm than good.
Many homeowners ask, “Can pressure washing damage my house?” And the answer is yes — especially if it’s done incorrectly.
Improper pressure washing in the fall can result in structural damage, safety hazards, and expensive repairs. The risks multiply when temperatures drop, surfaces get slick, and runoff freezes overnight.
Let’s break down the dangers of DIY fall pressure washing — and why hiring pros like All Hands Pressure Washing is the safer, smarter choice.

1. Improper Water Pressure Can Cause Irreversible Damage
Pressure washers can reach up to 4000 PSI, which is far more than most residential surfaces can handle.
Common damage includes:
- Cracked or chipped siding
- Etched wood grain on decks or fences
- Dislodged roof shingles or flashing
- Broken window seals or cracked glass
Using the wrong pressure setting is one of the top mistakes DIYers make. Without experience, it’s easy to overdo it — and once the surface is damaged, there’s no easy fix.
2. Incorrect Angles Force Water Where It Shouldn’t Go
Fall cleanup often involves removing leaves and grime from high or hard-to-reach areas — like second-story siding or under rooflines. Many DIYers angle the spray upward to reach these spots, not realizing this can:
- Force water under siding and into insulation
- Cause mold growth inside the walls
- Damage soffits and fascia
- Lead to interior water damage over time
Professionals use extension wands and angled nozzles to direct water safely — always from top down, never bottom up.
3. Frozen Runoff Becomes a Slip Hazard
In the fall, temperatures can drop rapidly — especially overnight. That makes wet surfaces from pressure washing prime candidates for black ice the next morning.
You could end up with:
- Frozen patios, decks, or walkways
- Ice-covered stairs or handrails
- Increased risk of slip-and-fall accidents
- Damage to concrete from freeze-thaw cycles
At All Hands Pressure Washing, we account for weather forecasts, surface types, and runoff areas to ensure safe timing and execution of every fall job.
4. Lack of Protective Gear and Knowledge = Injury Risk
Pressure washers aren’t garden hoses — they’re power tools. DIYers who skip protective eyewear, gloves, or boots risk:
- Water injection injuries
- Debris ricocheting at high speed
- Cuts and bruises from spray recoil
- Falls from wet ladders or slick surfaces
Professionals are trained, insured, and properly equipped to handle this work with minimal risk to themselves — and your property.
5. No Insurance Means You’re On the Hook for Damage
One of the biggest dangers of DIY isn’t just the damage itself — it’s that you’re financially responsible for it.
If you blast a hole in your siding or crack a window, that’s coming out of your own pocket.
But when you hire an insured pressure washing company like All Hands Pressure Washing, you’re covered. Our technicians follow best practices, and if something does go wrong, we make it right — fast.
