What Should You Do Before a Power Washing Appointment?
Move outdoor furniture off the surfaces being cleaned, close all windows and doors, cover exterior electrical outlets, and pre-wet landscaping next to areas where cleaning solution will be used. Proper preparation makes the appointment faster, protects your property, and ensures every surface is accessible for cleaning.
Clear Outdoor Areas
Move patio furniture, potted plants, outdoor rugs, doormats, garden hoses, and any loose items away from surfaces to be cleaned. The crew will not move household items as part of the standard service. Clearing areas before arrival allows the crew to start immediately rather than waiting for items to be moved. For driveways and walkways: move vehicles and any equipment stored on the concrete. For decks: clear all furniture, grills, and planters.
Close All Windows and Doors
Power washing generates water spray that can reach windows and doors from a distance. Close all windows and doors on the exterior being cleaned before the crew arrives. Check for any windows that may be left open in upper floors adjacent to areas being washed. Ensure weather-stripping around doors and windows is intact gaps allow water intrusion at high pressure even from a distance.
Protect Outdoor Electrical Outlets and Fixtures
Cover exterior electrical outlets with waterproof tape or outlet covers before washing. Point out to the crew any outdoor electrical fixtures, security cameras, or smart home devices that need to be avoided or carefully cleaned around. Most professional crews work carefully around electrical fixtures but benefit from being told about any non-standard locations.

Pre-Wet Landscaping
If cleaning agents will be used (soft wash for siding or any chemical pre-treatment), pre-water all plants, mulch beds, and grass adjacent to the house before the crew begins. Pre-watered plants absorb less chemical runoff than dry plants. This step is particularly important if the house is surrounded by dense planting beds close to the foundation.
Power Washing Cost at a Glance
Standard single-family home: $250 to $650 for exterior walls, driveway, and sidewalk on one visit.
Large home or multiple surfaces: $550 to $1,300 for siding, driveway, deck, and fence on a larger property.
Single surfaces booked alone: driveway and sidewalk $75 to $350; deck, patio, or fence $100 to $350. Booked on their own they fall below the whole-visit range.
Method matters: pressure washing siding runs $212 to $447; soft washing the same siding runs $300 to $800.
Heavy grime or mold: Added cost for stubborn buildup needing more time and stronger solutions.
Overall range: $250 to $1,200 for a whole-home visit, averaging $450.
Planning Your Project Budget
The cost ranges in this article are based on industry data and are intended as planning benchmarks, not fixed prices. The actual cost for your project depends on your specific home, your local labor market, the current price of materials, and the scope the contractor confirms after a site inspection.
Always get at least two written quotes on equivalent defined scope before committing to any home services project. Wide price variation between quotes usually reflects differences in material quality, scope completeness (what is included and what is not), or contractor overhead and experience level rather than simple price competition.
Use the cost data in this article to ask better questions during the quoting process: What material is included? What does that per-square-foot or per-linear-foot rate include and exclude? Are permits, cleanup, and disposal included? What is the warranty on labor? These questions turn a quote into a comparable basis for decision-making.
Working With a Contractor on This Project
Getting the right outcome on any home services project starts before the work begins. A few consistent practices make the difference between a smooth project and a frustrating one.
Get at least two or three quotes. A single quote gives you no basis for comparison. Two or three quotes reveal the market rate for the work, expose scope differences between bidders, and let you assess contractor communication quality before any commitment is made. The lowest bid is not automatically the best value if the scope is thin or the materials are underspecified.
Ask for licenses and insurance before work starts. Verify current general liability insurance and, for any work involving workers on your property, workers compensation coverage. Licensing requirements vary by state and trade; confirm the specific requirements in your jurisdiction. A licensed contractor who carries appropriate insurance protects both parties if something goes wrong during the project.
Get the scope in writing. A written proposal that specifies materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms is the foundation of a professional engagement. Verbal agreements on any of these points invite misunderstanding. For any project over $500, written scope is non-negotiable.
Clarify the payment schedule upfront. A reasonable payment schedule ties major payments to project milestones: a deposit at signing, a payment at material delivery or project start, and a final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment upfront before work begins is a red flag in any trade.
