How often should a Sullivan's Island home be washed?

Most island homes look their best with a professional wash every 6–12 months. Homes under heavy tree cover or close to the marsh often need attention twice a year.

Is soft washing safe for older and historic homes?

Yes. Low pressure is exactly what older siding, wood trim, and painted surfaces need. We match our method to each surface so nothing gets damaged.

Can you clean my roof without voiding the warranty?

Yes — soft washing is the method shingle manufacturers recommend. We never use high pressure on a roof.

Do you ever use high pressure on a house?

Never on siding, trim, or roofs. Higher, controlled pressure is reserved for the surfaces built to take it, like concrete driveways and walkways. On the house itself, it is always a gentle, low-pressure wash.

Do I need to be on the island during the service?

No. As long as we can reach exterior water and any gates, we handle everything while you are away and send photos of the finished result.

Are you licensed and insured?

Yes. TrueWash is licensed and insured with $2 million in liability insurance, and every job is backed by our 100% satisfaction guarantee.

Can you keep my home clean year-round?

Yes. A maintenance plan puts your home on a regular wash schedule, so salt film, mildew, and algae are handled before they build up — one less thing to think about on the island.

Gentle care for island homes

Between the ocean on one side and the marsh on the other, Sullivan's Island homes see constant moisture and salt. Shaded porches, elevated pilings, and mature landscaping make things worse — algae and mildew settle into siding, railings, and shaded roof lines, leaving the green and black staining every island homeowner knows.

Many houses on the island are older or built with materials that do not forgive high-pressure blasting. That is why we soft wash: low pressure and surface-appropriate solutions that break down growth at the root without forcing water behind siding, stripping paint, or scarring wood. Your home gets thoroughly clean, and it stays cleaner longer because we treat the cause, not just the stain.

We are on Sullivan's Island every week, and island neighbors are some of our most loyal customers — from Station 12 to the back island.

A cleaning method that respects the island's character

Sullivan's Island guards its character closely, and its houses show why: older beach cottages with original wood siding, wide screened porches, and paint layers that have survived decades of storms sit alongside newer builds designed to blend in. Surfaces like these reward patience. Painted wood softens with age, older trim joints open just enough to let driven water in, and a careless wash can do damage that takes a carpenter to undo.

Our approach is to work with the house, not against it. We identify what each elevation is made of before we start, keep pressure low everywhere on the structure, and pay particular attention to porch ceilings, pilings, and the shaded faces where the marsh-side humidity feeds growth fastest. The goal is a home that looks freshly kept — never blasted.

Respectful of your home and your time

We show up when we say we will, protect your landscaping and outdoor furniture, and walk the property with you when the work is done. If you are off-island, no problem — we handle everything and send photos of the finished result.

If you would rather never think about exterior upkeep again, ask about a maintenance plan: scheduled visits that keep your home clean year-round, before salt film and mildew get a chance to build.
