According to the 2016 National Association of Realtors, house washing can add $10,000 to $15,000 to the sale price of some houses. House washing is essential for removing, dirt, mildew, and mold from the exterior of your home that can cause damage if ignored. It is also one of the lowest investment home improvement projects with the highest return.

Soft washing is a low-pressure, soft wash method to safely and effectively clean your home’s siding. Our Safe House Washing system is ideal for all types of home siding surfaces including vinyl, aluminum, cedar, and more. We treat surface stains with an application of our eco-friendly biodegradable cleaning solution followed by a steam rinse to leave your home looking its best. Our soft washing system incorporates a special low-pressure nozzle combined with biodegradable cleaning agents that allow for safe, easy cleaning without damaging exterior home surfaces.

Roof cleaning always carries a risk to landscaping and plant life. We can’t guarantee that your landscaping will not be affected by the cleaning process (and be cautious of anybody or company that makes such a promise). What we do guarantee is that we’ll take every precaution possible to protect your property, plant life included. We rinse plant life after cleaning to mitigate any overspray that occurred during your roof cleaning.
  • Make sure all windows and doors are shut tightly and locked up!
  • Make sure your pets are inside during the service.
  • We will need access to a functioning exterior water source.
Power washing your home can be risky when done by untrained individuals. To ensure the safety of your home, we recommend hiring a team of professionals to wash the exterior of your home with a pressure washer.
For our team to get the job done, you will need to provide us with:
  • Access to an exterior water source.
  • Outside Windows — Tightly shut and lock all windows to avoid moisture.
  • Inside Windows — Please remove all valuables from the window sill and provide access to the windows you wish to be cleaned.
  • Pet Owners — We ask for all pets to be contained during the cleaning.
  • Screen Cleaning — We will need to remove the screens from the window which will require access to the latch to release the screens. If your cleaning service includes screen cleaning we will remove all screens, clean, dry, and replace the screens.

The easy answer is ​“no”. We can properly clean your home without anyone being home during the time that we perform your cleaning services. We ask that you have all windows closed and that we have access to the exterior of your property. Should you not be home during interior window cleaning service, we ask that you provide us with a method to gain access. Please disable any alarm systems and secure any pets during our visit. Also, if you are aware of any windows or doors that may have leaking issues that you would supply a towel at those areas to absorb any water that may enter as a result of our cleaning processes. Your security is our top priority!
We wish we could control the weather and that every day would be sunny and warm, but as we all know this is unrealistic. In the event of light rain, we can still perform all required cleaning for windows, screens, roof, gutters, and siding, the rain will not impact our ability to complete the job. If the weather brings harsh storms then we will reschedule another time to return and complete the job.
