Why Mount Pleasant exteriors get dirty faster
Mount Pleasant's best features are hard on houses. The mature live oaks that shade lots in the Old Village and Snee Farm also keep siding damp and drop the organic debris that algae feeds on. North-facing walls under tree cover can show green film within months of a cleaning, while the sunny side of the same house stays clean for a year.
The housing mix matters too. Brick and Hardie-sided homes dominate Park West, Dunes West and Carolina Park, and both hold up beautifully as long as they are washed at low pressure so water never gets driven behind boards or into mortar joints. Marsh-front properties along the creeks add salt film on glass and metal on top of everything else.
None of this is a reason to worry. It is simply why a regular, correctly done exterior wash matters more here than in drier, more open parts of the country, and why most of our Mount Pleasant customers end up on a schedule.

Good to know
Mount Pleasant exterior cleaning FAQ
Straight answers, the same ones we give on the phone.
How much does pressure washing cost in Mount Pleasant?
It depends on the size of the home and what we are cleaning. House washes start around $350 and most full exterior details run between $800 and $3,500. We send a clear, clear quote up front, and most homeowners have a price the same day they reach out.
Will high pressure damage my siding?
It can, which is why we never use it on siding. Homes get a low-pressure soft wash. Only concrete and hard surfaces see high pressure.
How often should I have my home washed?
Most Mount Pleasant homes look their best with a wash every 12 months. Shaded lots and homes near the marsh often benefit from every 6 to 9 months, which is what the maintenance plan is built around.
Do I need to be home during the service?
No. As long as we can reach exterior water and any gates, we can complete the work while you are out and send photos of the finished result when we are done.
Is roof cleaning safe for shingle roofs?
Yes, when it is done at low pressure. We clean shingle and metal roofs with a gentle soft-wash approach, never high pressure, which can strip granules and shorten a roof's life.
Do you offer recurring maintenance plans in Mount Pleasant?
Yes. Two scheduled washes a year on one monthly price, priced from your own quote, with priority scheduling and a locked rate for 12 months. Ask about it when you request your quote, or see the plan page.
