TrueWash Exterior Cleaning · Downtown Charleston, SC

Soft Washing for Historic Homes in Downtown Charleston

Old stucco, soft mortar and painted wood were never built for a pressure washer. We clean them gently.

Short answer: TrueWash soft washes downtown Charleston homes at low pressure, with a rinse about as strong as a heavy rain. Most full house washes run $500 to $1,500, based on size. Tall three story homes can run higher, outside windows are free, and most homes take one day.

The peninsula

Old walls need a light touch

Downtown Charleston is full of historic homes. Many have old stucco, soft lime mortar, and wood with many coats of paint. High pressure can lift that paint and push water into old walls.

So we soft wash. A cleaning solution breaks down the mold and mildew at the root. Then we rinse at about the force of heavy rain.

Lots are tight, and homes sit close together. Many walls never see the sun, so they stay damp. Piazzas catch pollen and mildew on the ceilings, columns and rails.

Planning the visit

A calm day on a tight street

Before the visit, we ask where the truck can park. We plan how to reach each side of the home. That keeps the day simple for you and your neighbors.

Downtown Charleston FAQ

What downtown owners ask us most.

How much is a house wash downtown?

For a full house wash, plan on $500 to $675 under 2,000 sq ft. Plan on $600 to $800 for 2,000 to 3,000 sq ft. Plan on $700 to $950 for 3,000 to 4,000 sq ft, and $900 to $1,500 above that. Island and raised beach homes run higher. Tall three story homes can run higher. Outside windows are free with it, and we set the price in person.

Is soft washing safe for old stucco and brick?

Yes, that is why we use it. High pressure can push water into old stucco and soft mortar. We use low pressure and a rinse about as strong as heavy rain.

Do you clean piazzas?

Yes. Porch ceilings, columns, rails and floors are part of a full house wash. They collect pollen film and mildew fast.

How do you handle parking on a narrow street?

We plan it before the day. We ask where the truck can park and how to reach each side of the home.

Can you wash the house while I am at work?

Yes. We need an outside spigot and access to each side. We send photos of the whole house when we finish.
