Before a house washing crew arrives, move furniture and decor away from the walls, close windows and storm windows, cover or pre-water plantings against the foundation, clear vehicles from the driveway, unlock gates, and secure pets indoors. Most of it takes under an hour and it is the difference between a crew washing your house and a crew spending the first hour moving your things.
Key Takeaways
- Give the crew a clear three to four foot working lane around the whole perimeter
- Close and latch every window, storm window, and basement hopper before the crew arrives
- Pre-water garden beds against the foundation; damp soil dilutes any runoff that reaches it
- Unlock gates and note where the outside water spigots are
- Flag known problem areas rather than waiting to see if the crew finds them
Why the Prep Matters
House washing is not a delicate operation, but it is a wet one, and water goes where gravity and spray angle send it. Most of the small problems that come out of a wash day are preventable in the hour before the crew arrives: an open window on the second floor, a cushion left on a chair against the wall, a gate the crew cannot get through with a hose reel.
None of this is the homeowner's job in a strict sense. A good crew will handle what they find. But a prepared property gets washed faster, more thoroughly, and with less risk of something getting wet that should not have.
Landscaping and Garden-Bed Preparation
Plantings against the foundation are the most common concern, and the answer is simpler than most homeowners expect.
- Water the beds thoroughly an hour or two before the crew arrives. Soil and foliage that are already saturated absorb far less of anything that runs off the wall. This is the single most effective thing you can do for your plants.
- Trim back anything touching the siding. Shrubs pressed against a wall keep it damp, hide the surface from cleaning, and get in the way of the wand. A few inches of clearance helps the wash and the wall.
- Move potted plants and hanging baskets out from under the eaves and away from the walls entirely. They are easy to relocate and impossible to protect in place.
- Flag anything you particularly care about. A newly planted specimen, a vegetable bed, a delicate perennial. Point it out rather than assuming it will be recognized as different from the rest of the border.
- Mulch beds can be covered if you would rather, though pre-watering usually does more good than plastic sheeting, which traps runoff against the plants underneath it.
Outdoor Furniture, Toys, and Decor
Anything within about ten feet of the house should either move or be prepared to get wet.
- Patio furniture, cushions, and umbrellas: move them well clear, not just a few feet along the wall
- Grills, smokers, and outdoor kitchens: cover or relocate, and close the lid
- Children's toys, play equipment, and trampolines near the house
- Door mats, planters, wreaths, and seasonal decor on the porch and entry
- Wind chimes, hanging lanterns, flags, and anything mounted to the siding itself
- Bird feeders and baths, which should be emptied rather than just moved
- Vehicles, motorcycles, boats, and trailers parked close to the walls or in the drive
Cars are worth calling out separately. Even a careful wash produces overspray and drift, and cleaning solution drying on a vehicle finish is an avoidable annoyance. Move them to the street or the far end of the drive.
Protecting Doors, Windows, Outlets, and Utilities
This is the part homeowners most often skip, and the part most likely to cause an actual problem.
- Close and latch every window, including storm windows, basement hoppers, and any window that is painted or swollen and does not close fully. A window that looks shut but is not sealed will let water in.
- Close and latch exterior doors, including garage side doors, sheds, and bulkheads.
- Cover exterior outlets and any outdoor electrical box with a taped plastic cover if they do not have weatherproof flip covers already.
- Note any light fixture with a compromised seal, particularly older sconces and soffit lights that have taken on water before.
- Flag the HVAC condenser and any exterior vent so it is covered rather than sprayed directly.
- Point out attic and gable vents if you know of past leaks. Vents are designed to shed rain falling downward, not water arriving at an upward angle.
If your house has a known trouble spot, a window that has always leaked, a section of trim with soft wood, say so before work starts. A crew that knows about it will work around it. A crew that discovers it mid-wash is finding out the same way you will.
Access, Pets, Vehicles, and Communication
The crew needs to physically get around the house with equipment and hose.
- Unlock every gate and prop open any that latch on their own
- Clear a working lane of roughly three to four feet around the full perimeter where you can
- Show them the outside spigots, or leave a note about which ones work and which do not
- Secure pets indoors for the duration, and be aware that dogs in particular react badly to pressure equipment noise. Bring in outdoor water bowls
- Move or note anything buried that a boot or a ladder foot could damage: irrigation heads, low-voltage landscape lighting, septic covers, French drain outlets
- Confirm who will be home, or how to reach you if a decision needs making
If neighbors share a driveway, a fence, or a party wall with you, a heads-up the day before avoids the awkward conversation on the day.
What the Crew Should Confirm on Arrival
Preparation runs in both directions. Before any water goes on the house, expect the crew to walk the exterior with you or to document it, and to confirm:
- What surfaces are in scope, and the method for each one, since siding, masonry, and hardscape should not all get the same treatment
- Any pre-existing damage they can see, called out before work begins rather than discovered afterward
- Where the water source and staging area will be
- Roughly how long the job will take and whether you need to be home
- What they need moved that you have not already moved
That walk-through takes five minutes and it is the clearest signal of whether you have hired someone who works from an assessment or from a template. Our guide on questions to ask before hiring a siding cleaning company covers what to expect from that conversation.
