Will Exterior Cleaning Damage My Plants or Windows?
Many people wonder about this before they book. It deserves a plain answer. Here is what really happens to your plants, windows, furniture, pets, and kids on cleaning day.
Short answer: A careful soft wash is very unlikely to harm your plants or windows. We wet plants before and rinse them after, and we never use high pressure on siding, windows, or roofs. Most homes are done in one day, and outside windows are cleaned free with every full house soft wash.
Plants: what protection really means
Protecting plants is not one step at the start. It runs through the whole job:
- We wet the beds before any cleaner goes on.
- We rinse plants during the wash, not just after.
- We give the beds a final rinse when the wall is done.
- We guide runoff away from delicate plants.
- We move or shield small pots near the walls.
- We ask which plants you care about most.
Wetting plants first matters more than most people think. A plant that is already soaked takes in much less of anything that lands on it. So soaking the beds first does real work.
Here is the honest part. No careful company can promise that every plant in every yard will be fine. Grown shrubs and lawns handle a well protected wash with no trouble. New beds, fresh sod, delicate plants, and plants stressed by heat or dry weather are at more risk. That is why protection and talking with you matter so much. Maybe you have a Japanese maple you have cared for six years. Maybe there is a vegetable garden on the south wall, or a bed that went in last month. Tell us when we arrive, and we will plan around it.
Windows, screens, and seals
High pressure does the most hidden damage to windows. Here is why. A strong jet does not just hit the glass. It hits the edges, where the seals and caulk are. Enough force in the wrong spot can push water past the seals. Water that gets between the panes or behind the trim does not come back out.
We do not use high pressure on siding. That rule protects your windows as much as your walls. A low pressure rinse is more like a heavy Lowcountry rain than a jet. A sound window handles it the same way it handles a storm.
We handle screens with care. They trap dirt and hold water. A screen that gets wet during the wash can dry with spots and streaks. So we either move screens out of the way or work around them. If they need to come off, we ask you first. We do not pull hardware off your house without asking.
Outside window cleaning comes free with every full house soft wash. We finish the outside glass with a rinse with filtered water that dries without spots. This covers outside windows only.
Furniture, grills, electronics, and lights
Everything on the outside of the house gets a plan before the water starts:
- Furniture and cushions Cushions and soft items should come inside or be moved away. We move furniture away from the walls or cover it.
- Grills and outdoor kitchens We roll grills out of the way when we can and cover them when we cannot. Grill covers stay on.
- Electronics and outlets We cover or avoid cameras, speakers, doorbells, and outside outlets.
- Light fixtures We cover lights or work around them, since older ones can hold water inside. If a fixture is broken or open, we tell you instead of spraying it.
You do not need to clear your yard the night before. The crew moves and covers things when they arrive. The one thing to do yourself is bring in anything of real value.
Pets and kids on cleaning day
Keep pets inside while the crew works. That is as much about hoses, equipment, and open gates as anything else. Dogs love to follow a crew around the yard. An open side gate is how a dog ends up in the street.
The same goes for kids. Keep them inside or out of the work area until the wall is done and the beds have had their final rinse. Do you have a dog run, a water bowl, or a play area near the house? Tell us, and we will rinse and clear that space before we leave.
If you notice a problem after
Tell us. That is the whole policy, and we mean it.
Maybe a plant looks stressed a few days later. Maybe a window has spots you do not like, or a corner of the house did not turn out the way you hoped. Call or text, and we will come back and make it right. We send photos of every side when the job is done. That way you can see the work and point out anything that looks off while it is fresh.

Plant and window safety FAQ
- Will house washing kill my plants?
- Careful protection makes plant damage unlikely. Still, no careful company can promise every plant in every yard will be fine. We wet plants before we start, rinse them during the wash, and rinse again at the end. We also guide where the runoff goes. The most helpful thing you can do is tell us about plants you love or new plantings.
- What should I do to prepare my landscaping?
- Not much. Point out the plants you care about most. If it is easy, move small pots a few feet from the walls. Tell us about new sod, new plants, or a vegetable garden near the house. We handle the rest when we arrive.
- Can exterior cleaning break a window seal?
- High pressure aimed at glass or the frame can push water past the seals. That is one reason we never use high pressure on siding or near windows. A low pressure rinse is more like heavy rain. A sound window handles it the same way it handles a storm.
- What happens to my window screens?
- Screens hold dirt and water and can show spots once they dry. So we either move them out of the way or work around them. If screens need to come off, we ask you first.
- Will I have water spots on my windows afterward?
- Outside window cleaning comes free with every full house soft wash. We finish the outside glass with a rinse with filtered water that dries without spots. If you do see a spot you do not like, tell us and we will come back.
- What if I notice a problem after the crew leaves?
- Tell us, and we will make it right. We send photos when the job is done so you can see the work. Every job has a 100% satisfaction guarantee. TrueWash is licensed and $2 million insured.
