What's Included
What's Included With Every House Wash
Exterior Materials We Clean in Jacksonville
Jacksonville homes are built with a wide range of exterior materials, and each requires a different approach. Vinyl siding is the most common and responds well to soft washing — high pressure can warp panels or force water behind the wall cavity. Stucco is porous and holds moisture, making it especially prone to algae and mildew; our low-pressure application cleans deep without saturating the substrate. Brick and Hardie board are more durable but still benefit from soft washing to avoid surface erosion and paint damage over time.
Florida's warm, humid climate creates near-ideal conditions for algae, mold, and mildew growth year-round. Homes near wooded areas, retention ponds, or with significant shade accumulate organic buildup faster than those in open, sunny locations. North-facing walls and shaded soffits are typically the first surfaces affected — often turning dark green or black within months of a cleaning if conditions are right.
Most Jacksonville homeowners benefit from exterior washing every 6–12 months. Heavily shaded properties or homes near water typically need cleaning closer to every six months to prevent buildup from becoming established and causing long-term surface damage.
Our Process
How It Works
Pre-Wet & Protect
We pre-wet landscaping, plants, windows, and surrounding surfaces before applying any solution.
Customized Solution
We apply a customized Seal Deal cleaning solution, adjusting concentration for the exterior material and buildup.
Dwell & Rinse
After 5–10 minutes of dwell time, we thoroughly rinse the home using appropriate low pressure.
Final Walkthrough
We finish by rinsing nearby landscaping and walk the property to ensure every surface meets our standard.
Real Project
A Real House Washing Project: Blackened Soffits & Heavy Mildew
We cleaned a home with heavily blackened soffits, mildew, and insects around the exterior.
During the job, our team encountered a wasp nest approximately the size of a football. We removed it during that particular project, cleaned the surrounding area, and took precautions for the homeowner's safety.
After cleaning, the exterior looked dramatically better, and the homeowner was satisfied with the results.
This was an unusual project; pest and wasp-nest removal are not standard house washing services.
Know Before You Book
What Jacksonville Homeowners Should Know
Soft Washing vs. High-Pressure Washing
Soft washing uses low pressure — similar to a garden hose — combined with professional-grade cleaning solutions that break down organic growth at the source. High-pressure washing can strip paint, force water behind siding, and damage caulk and window seals. For most home exteriors in Jacksonville, soft washing delivers a deeper clean with less risk to the surface.
Why Florida Humidity Speeds Up Buildup
Jacksonville's warm, humid climate creates near-ideal conditions for algae, mold, and mildew growth on exterior surfaces. Homes near wooded areas, retention ponds, or with heavy shade tend to accumulate organic buildup faster. North-facing walls and shaded soffits are often the first areas affected.
How Often Should You Wash Your House?
Most Jacksonville homes benefit from exterior washing every 6–12 months. Florida's year-round humidity, heavy tree canopy, and proximity to water mean organic buildup can establish quickly — regular washing is the most cost-effective way to maintain your home's appearance and protect the exterior surfaces.
What Affects House Washing Prices?
House washing pricing depends on the home's square footage, number of stories, accessibility, and the level of buildup. Homes with extensive mildew, difficult-to-reach areas, or surfaces requiring special treatment may cost more than a straightforward single-story wash. We provide a specific quote for every property — no guessing from a price list.
