If you own a home in Westover Hills (19807) or Greenville (19807), you already know that keeping the exterior clean is a different challenge than in newer subdivisions. These are older, well-maintained neighborhoods with brick colonials, stucco facades, natural stone accents, and mature tree canopy that holds moisture against your siding for months at a time. That shade and humidity is a perfect recipe for green algae, black mildew streaks, and that general gray dullness that creeps in every spring. True Blue Pro Wash specializes in soft washing for exactly this kind of home, and we work in Westover Hills, Greenville, and throughout the 19807 zip code every week.
Soft washing is not pressure washing. We use a low-pressure rinse combined with professional-grade, biodegradable cleaning solutions that kill algae and mildew at the root rather than blasting it off the surface. High-pressure water on older brick mortar, painted wood trim, or stucco can cause real damage. Soft washing gets the job done safely. The results typically last two to four times longer than a pressure wash alone because the biology causing the staining is eliminated rather than just displaced.
Why Westover Hills and Greenville Homes Get Dirty So Fast
The Brandywine Valley region has humid summers that rival almost anywhere in the Mid-Atlantic. Between May and September, Wilmington averages enough moisture and heat to turn north-facing and shaded exterior walls green within a single season. Pollen from the heavy tree canopy in Greenville and along Westover Hills Road coats siding and then bonds with moisture and organic debris to feed algae colonies. Come winter, freeze-thaw cycles crack that organic layer into the surface of porous materials like brick and stucco, making it even harder to remove without the right chemistry. By the time spring rolls around, many homeowners in this area are dealing with walls that look like they haven't been washed in years even if they were cleaned just eighteen months ago.
What Our Soft Washing Process Looks Like on Your Home
Before we touch anything, we do a walk-around with you or your property manager. We identify the siding material, note any areas of concern like loose caulk, older mortar joints, or sensitive plantings, and flag any spots that need extra attention. Then we pre-wet surrounding landscaping to protect it from any overspray. Our team applies a surfactant-based cleaning solution at low pressure, lets it dwell long enough to kill the biology on contact, and then rinses everything clean. For homes with brick or natural stone, we adjust the mix to be gentler on those surfaces while still being effective against algae and mildew.
Siding Types We Soft Wash in the 19807 Zip Code
- Painted and unpainted brick, common in Westover Hills colonials and ranches
- Stucco and EIFS, found on many Greenville estates and custom builds along Kennett Pike
- Vinyl and aluminum siding on postwar homes in the Westover Hills neighborhood proper
- Natural stone and fieldstone on larger Greenville properties
- Wood and composite siding on additions and smaller homes throughout the 19807 area
- Cedar shake siding, which requires extra care to avoid water intrusion
Common Problem Spots on Westover Hills and Greenville Homes
We see the same patterns on homes throughout this part of Wilmington. The north-facing gable ends and foundation walls are almost always the worst because they see the least direct sun and stay damp longest after rain. Overhanging soffits and the underside of porch ceilings collect dirt, spider webs, and insect nests that stain the paint over time. Driveways and walkways made of brick pavers or flagstone in Greenville developments pick up algae and moss in the joints, which can make them slippery and shorten the life of the joint sand and sealant. We can address all of these as part of a full-exterior wash or as standalone services.
How Often Should You Wash Your Home in This Area?
For most homes in Westover Hills and Greenville, we recommend a full soft wash every one to two years. Heavily shaded properties along the Brandywine Creek corridor or on lots with significant tree cover may need attention annually. Homes with lighter-colored siding or stucco show algae growth sooner and benefit from staying on the shorter end of that cycle. Many of our Wilmington customers schedule us every spring after pollen season winds down, which is typically late April through May. That timing gets the pollen, the winter grime, and any early-season algae growth all at once and sets the home up to look its best through the summer.
Signs It Is Time to Call Us
- Green or gray streaking on siding, especially on north-facing and shaded walls
- Black mildew spots near downspouts, window sills, or roof drip lines
- A general dulling or yellowing of painted or vinyl surfaces
- Slippery walkways or patio surfaces caused by algae or moss growth
- White or gray chalking on painted brick or stucco
- Visible cobwebs, insect nests, or mud dauber tubes on soffits and eaves

Frequently Asked Questions
Is soft washing safe for older brick homes in Westover Hills?
Yes. Soft washing uses low water pressure, well below what a standard garden hose produces at the nozzle, combined with cleaning solutions that do the actual work. This is far safer for older brick, mortar joints, and painted surfaces than high-pressure washing, which can erode mortar and drive water behind siding.
Will the cleaning chemicals harm my landscaping or garden beds?
We pre-wet all landscaping before applying any solution and rinse it thoroughly afterward. Our products are biodegradable and break down quickly. We have worked around the mature plantings and gardens common in Greenville and Westover Hills properties without issue. If you have particularly sensitive plants, let us know when you call and we will take extra precautions.
How long does a typical house soft wash take in the 19807 area?
Most single-family homes in Westover Hills and Greenville take between two and four hours depending on size, the amount of algae buildup, and whether we are also cleaning walkways, a patio, or gutters. Larger estate properties in Greenville along Kennett Pike or Barley Mill Road may take longer. We will give you a realistic time estimate when we quote the job.
Do I need to be home during the soft washing service?
You do not need to be present as long as we have access to an outdoor water spigot and can reach all sides of the home. Many of our customers in Westover Hills and Greenville leave us a note and go about their day. We will send before and after photos and follow up when the job is done.
How soon after soft washing can I expect to see results?
Most of the visual change happens immediately as the rinse clears away the loose algae and grime. Some organic staining, especially on porous stucco or brick, continues to lighten over the following few days as the cleaning solution finishes working. By three to five days after service, your home should be at its cleanest.
Do you also clean driveways and gutters in the Westover Hills and Greenville area?
Yes. We offer concrete and paver driveway cleaning, gutter cleaning and brightening, and gutter guard installation throughout the 19807 zip code. Many customers bundle a house wash with a driveway cleaning or gutter service and save on a combined visit. Ask us about package pricing when you call (302) 757-9755.
