Frequently Asked Questions

Pressure washing uses high-pressure water to clean hard surfaces like driveways and concrete, while soft washing uses low pressure with biodegradable solutions for delicate surfaces like roofs and siding. Soft washing is safer for shingles, wood, and painted surfaces, preventing damage while effectively removing mold and algae.

Soft washing uses eco-friendly, biodegradable solutions applied at low pressure to break down algae, mold, and moss at the root level without harming shingles. This method is much gentler than high-pressure washing, which can strip granules and reduce roof lifespan. At C & J Exterior Cleaning LLC, we use this technique to safely restore roofs throughout Hendersonville.

Roof washing is best done in spring or fall when temperatures are moderate and humidity levels support effective treatment of mold and algae. Hendersonville's humid climate encourages frequent algae growth, so scheduling every 1–2 years helps maintain roof integrity and curb appeal.

Black streaks are caused by algae called Gloeocapsa Magma, which thrives in humid climates like Hendersonville and Asheville. This algae feeds on limestone filler in shingles and retains moisture, which can lead to premature roof deterioration. Soft washing removes it safely and prevents costly damage.

When done correctly, pressure washing won't damage concrete, but excessive pressure or improper technique can etch surfaces or widen cracks. Professional services adjust pressure based on surface type and condition. At C & J Exterior Cleaning LLC, we use specialized concrete washing methods to remove stains without causing harm.

Most homes benefit from exterior washing every 12–18 months to remove dirt, mold, and mildew that accumulate over time. Homes in shaded or wooded areas may need more frequent cleaning due to increased moisture and organic debris.

Professional porch staining involves cleaning the surface, repairing damaged boards if needed, applying high-quality stain, and sealing to protect against weather and UV damage. This process enhances appearance and extends the life of wood decks and porches, especially important in Hendersonville's variable climate.

Soft washing uses biodegradable solutions that kill mold, mildew, and algae at the source, rather than just blasting them away with force. This approach is gentler on vinyl, wood, and painted siding, preventing water intrusion behind panels and preserving finishes longer.

Cost depends on home size, surface type, level of buildup, and accessibility. Homes with heavy mold or multi-story structures require more time and specialized equipment. Additional services like gutter cleaning or window washing can also impact pricing.

Remove or cover outdoor furniture, close all windows and doors, and move potted plants or decorations away from work areas. Clear driveways and walkways of vehicles and obstacles to allow full access. At C & J Exterior Cleaning LLC, we'll walk you through any additional prep based on your specific service.

Yes, moss retains moisture against shingles, leading to rot, lifted shingles, and premature deterioration. Its roots can work under shingle edges, compromising the roof's protective barrier. Soft washing removes moss safely and helps extend the lifespan of your roof.

Using too much pressure or the wrong cleaning method is the most common mistake, often resulting in damaged siding, stripped paint, or broken shingles. DIY pressure washing without proper training can also force water into walls or under roofing materials, causing hidden damage and costly repairs.
