Q: What's the difference between pressure washing and soft washing?

Pressure washing uses high-pressure water to clean hard surfaces like concrete driveways, sidewalks, and pool decks. Soft washing uses low-pressure water combined with specialized cleaning solutions to safely clean delicate surfaces like roofs, stucco, painted siding, and screen enclosures. We use the right method for each surface to get the best results without causing damage.

Q: Is soft washing safe for my roof?

Yes. Soft washing is the method recommended by shingle manufacturers like GAF and CertainTeed. High-pressure washing can strip granules from shingles, voiding your warranty. Our soft wash process kills algae, mold, and mildew at the root using a low-pressure chemical application that's safe for your roof and your landscaping.

Q: How often should I have my home or driveway cleaned?

In our Martin County climate, we recommend house washing once a year and driveway or flatwork cleaning every 12 to 18 months. Roofs typically need cleaning every 2 to 3 years, depending on shade and exposure. Properties with heavy tree cover or north-facing surfaces may need more frequent attention.

Q: What causes the black streaks on my roof?

Those black streaks are caused by Gloeocapsa magma, a type of algae that feeds on the limestone filler in asphalt shingles. It's extremely common in humid coastal climates like ours. Soft washing eliminates the algae and restores your roof's appearance.

Q: Will pressure washing damage my pavers or concrete?

Not when done correctly. We use professional surface cleaners that distribute pressure evenly across the surface, preventing etching and stripping that can occur with a wand tip alone. We also adjust pressure settings based on the surface material and condition.

Q: What about my plants and landscaping?

We take steps to protect your landscaping during every job. Before applying any cleaning solutions, we pre-wet the surrounding plants and ground cover. After the job, we rinse everything thoroughly. The solutions we use are biodegradable and break down quickly, but we still take precautions to minimize any contact with vegetation.

Q: Do you offer free estimates?

Yes. We provide free, no-obligation estimates for all residential and commercial properties in Stuart, Jensen Beach, Sewalls Point, and Palm City. You can request an estimate right through our website or give us a call.

Q: Are you licensed and insured?

Yes. Coastie Power Washing is fully insured and operates as a veteran-owned LLC in Martin County, Florida.

Q: What forms of payment do you accept?

We accept credit cards, debit cards, ACH bank transfers, and checks. Payment is processed through our Jobber system, which sends you a digital invoice you can pay online.

Q: How long does a typical job take?

A standard driveway cleaning takes about 1 to 2 hours. A full house wash usually takes 1 to 3 hours, depending on the size of the house. Larger commercial jobs or multi-service visits may take longer, and we'll provide a time estimate when we issue your quote.

Q: Do I need to be home during the service?

Not necessarily. As long as we have access to the areas being cleaned and a working water source, we can complete most jobs without your presence. We'll communicate with you before, during, and after the job so you know exactly what's happening.

Q: What's the rust staining on my driveway and sidewalk?

Rust stains are almost always caused by your irrigation system. The well water in Martin County has high iron content, and when sprinklers overshoot onto concrete, the iron oxidizes, leaving orange-brown staining. We offer specialized rust removal treatment using oxalic acid-based products that safely dissolve the staining without damaging the concrete.
