How often should I clean my siding?

Frequency of house washing on Cape Cod can depend on various factors, including your specific location and the type of siding you have. As a general guideline,  scheduling a professional house washing service every 2-3 years is often ideal. That's if you want to keep your siding pristine looking! Often, what we find, is we'll go to a client's home for a thorough top-to-bottom power washing service every 3-4 years and they can get away with a DIY rinse once a year. This maintenance routine helps prevent the build-up of dirt, mold, and other contaminants that can affect your home's curb appeal. However, in areas prone to high humidity or heavy rainfall, more frequent house washing, perhaps annually, may be beneficial. Regular inspections and attention to the changing conditions around your home will help determine the optimal cleaning schedule for maintaining the beauty and longevity of your Cape Cod house siding.

What method will Street Appeal Pros use to clean my vinyl siding?

For optimal results, we use a method that uses eco-friendly cleaning solutions coupled with low-pressure power washing to achieve a thorough and gentle clean. Our technicians use reduced PSI and custom tooled soft tip nozzles to preserve the integrity of the vinyl siding while ensuring a long-lasting and appealing result. 

What is the difference between power washing and soft washing?

At Street Appeal Pros, we exclusively use power washing, steering clear of soft washing due to the environmental and health hazards. We understand the concerns associated with bleach exposure that go hand in hand with "soft washing", and by avoiding its use, we prioritize the safety of both residents and the greater environment. 

Unlike traditional power washing, we utilize low PSI (pounds per square inch) along with custom tooled soft-tip nozzles, effectively reducing the pressure impact by up to 80%. This careful and strategic technique allows us to achieve a thorough clean without compromising the integrity of delicate surfaces. Street Appeal Pros ensures a meticulous and eco-friendly power washing service that not only enhances the appearance of your home but also considers the health and environmental factors that matter to you.

Do I need to prepare my home before power washing?

Preparing your home before power washing is key to ensure a safe and effective cleaning process. Here are some essential steps to take:

Remove Outdoor Furniture and Decor:

  • Clear the area around your home by removing outdoor furniture, decorations, and any items that could obstruct the power washing process.

Close Windows and Doors:

  • Ensure all windows and doors are tightly closed to prevent water from entering your home during the power washing.

Clear Driveways and Walkways:

  • Clear your driveway and walkways of any vehicles or obstacles to allow for unobstructed access during the power washing.

Secure Pets:

  • Keep your pets indoors or in a secure area to ensure their safety and prevent interference with the power washing process.
