What Impacts the Cost of Pressure Washing?
There are a few things that come into play.
Home Size and Elevation
We need more labor and safety protocols for the larger or elevated homes that are common in Mount Pleasant and Isle of Palms. We also need to use more cleaning supplies and take extra time.
Surface Type
How much does pressure washing cost vary according to the materials? That depends on how hardy they are. We can apply significantly more force to concrete than to shingles, which makes cleaning quicker.
Accessibility and Time Required
We’ll need to assess porches, decks, intricate landscaping, and multi-level access points individually.
Service Scope
The cost increases with add-ons like window and roof cleaning.
Cleaning Complexity
We may need to use stronger chemical mixes if there’s a lot of mold or algae.
DIY vs. Professional
Many people think they’ll save a fortune by cleaning themselves. However, they don’t factor in the time, cost, and risk of damage.
