If you live in Bear or Glasgow, you already know the drill. Spring arrives, pollen blankets everything in yellow-green dust, and by July the north-facing walls of your house are showing dark streaks and fuzzy green patches. It is not just cosmetic. That green film is living algae and mildew working into your siding, and the black streaks on vinyl and fiber cement are Gloeocapsa magma, a cyanobacteria that feeds on moisture and airborne dust. Left alone, both shorten the life of your exterior surfaces and quietly chip away at curb appeal and resale value.
True Blue Pro Wash serves the 19701 zip code, including the communities around Bear, Glasgow, Glasgow Commons, Becks Pond, and the newer subdivisions off Route 40 and Glasgow Pike. We use soft washing, which means low-pressure application of professional-grade biodegradable detergents that kill the organic growth at the root, followed by a gentle rinse. There is no high-pressure spray blasting joints apart or stripping paint. The biology dies, the surface stays intact, and the clean lasts.
Why Bear and Glasgow Homes Get So Dirty So Fast
New Castle County sits in a humidity corridor. Summers are long, wet, and warm, and the freeze-thaw cycles from November through March keep moisture trapped in siding seams, wood trim, and behind gutters. Bear specifically has a lot of tree cover in established neighborhoods like Brennan Estates, Beckett, and areas near Lums Pond State Park. More tree canopy means more shade on the north and east walls, more trapped moisture, and faster algae and mildew colonization. Add in the heavy pollen season that runs from late March through May, and exterior surfaces collect organic material that acts as fertilizer for exactly the organisms you do not want on your house.
What Our Soft Washing Process Looks Like at Your Home
When we pull up to a house in the 19701 zip code, we start by walking the property with the homeowner. We look at siding type, paint condition, the location of landscaping beds, downspout positions, and any areas that need extra attention like window frames, soffits, and fascia boards. Then we wet down all plantings and cover anything sensitive before we start applying product.
- Pre-wet all landscaping beds and shrubs to protect them from surfactant runoff
- Apply a low-concentration sodium hypochlorite and surfactant mix at low pressure to all siding surfaces
- Work from the bottom up to avoid streaking and ensure even coverage
- Let the solution dwell long enough to kill algae, mildew, and bacteria at the root level
- Rinse thoroughly from the top down at low pressure, flushing residue away from the foundation
- Inspect every elevation with the homeowner before we pack up
Siding Types We Soft Wash in the Bear and Glasgow Area
The housing stock in Bear and Glasgow is a mix of vinyl, aluminum, brick, and fiber cement, with a lot of the builder-grade vinyl siding that went up during the subdivision boom of the 1990s and 2000s. That older vinyl is especially prone to oxidation, which shows up as a chalky, faded look even after the algae is removed. We treat oxidation with a dedicated vinyl brightener as part of the wash process when needed. Brick homes near Glasgow Commons get a different mix, dialed back on sodium hypochlorite to protect mortar joints while still killing the green and black growth in the texture of the brick.
Surfaces We Clean on a Full House Wash
- Vinyl, aluminum, and fiber cement siding panels
- Wood soffits and painted fascia boards
- Window frames, shutters, and trim
- Brick and stone veneer facades
- Covered porches, columns, and railings
- Garage doors and door surrounds
How Often Should Bear and Glasgow Homeowners Schedule a House Wash?
Most homes in the 19701 area benefit from a professional soft wash every one to two years depending on tree cover and sun exposure. If your house sits in full sun with no large trees close to the walls, you can likely go two seasons between washes. If you are in one of the more wooded sections of Bear, or your home has a significant north-facing or east-facing wall that rarely sees direct afternoon sun, plan on annual cleaning. Waiting until you have a thick coat of algae means more product, more dwell time, and sometimes a second pass, which adds cost. Staying on a regular schedule is almost always cheaper in the long run.
We work throughout Bear and Glasgow from early spring through late fall. Our busiest windows are April through June before the worst summer heat, and again in September and October when homeowners want the house looking sharp heading into the holiday months. Call (302) 757-9755 early to get on the schedule during those peak windows.

Frequently Asked Questions
Is soft washing safe for the vinyl siding on my Bear, DE home?
Yes. Soft washing uses low water pressure, well below what a standard garden hose delivers at full blast. The cleaning is done by the detergent chemistry, not by force. It is safe for vinyl, aluminum, wood, fiber cement, brick, and painted surfaces when applied by a trained technician using the right dilution for each surface type.
Will the cleaning chemicals harm my landscaping or grass?
We take precautions on every job. Before we start, we wet down all plantings, shrubs, and grass around the house. After rinsing, we flush the beds again. The surfactants we use are biodegradable and break down quickly once diluted with rinse water. We have never had a landscaping loss when proper pre-wetting and rinsing steps are followed.
How long does a full house soft wash take in Bear or Glasgow?
Most single-family homes in the 19701 area take between two and four hours depending on size, siding condition, and the extent of algae or mildew growth. We do not rush the dwell time because letting the solution work properly is what makes the clean last. We will give you a time estimate when we quote the job.
What is the black streaking on my siding and roof and can soft washing remove it?
Black streaking on siding and roofing is almost always Gloeocapsa magma, a cyanobacteria that thrives in the humid Mid-Atlantic climate. It spreads through airborne spores and feeds on moisture and organic debris. Soft washing with the correct solution kills it and removes the staining. Pressure washing alone just pushes it around and can damage surfaces without actually killing the organism at the root.
Do I need to be home during the house washing appointment?
We ask that someone be available at the start of the job so we can do a walkthrough together and confirm any specific concerns you have. Once we begin, you do not need to stay outside with us. We just ask that all windows and doors are closed and exterior electrical outlets are covered, which we can help with before we start.
Does True Blue Pro Wash offer any other services for Bear and Glasgow homeowners?
Yes. In addition to house soft washing, we handle roof soft washing, concrete and driveway cleaning, wood deck and fence cleaning, gutter cleaning and brightening, gutter guard installation, and rust and oxidation stain removal.
