If you live in Newark, Delaware and you have not had your house washed in the past couple of years, take a walk around to the north-facing side and look up. Odds are you will find a green or gray film creeping up from the foundation line toward your soffits. That is not just dirt. That is a combination of green algae, mildew, and biological buildup that thrives in the Mid-Atlantic humidity we get every summer. Newark sits in the heart of New Castle County, and the tree cover, the shade from mature oaks and maples, and the moisture that rolls in off the Christina River corridor makes homes in the 19711 and 19713 zip codes especially prone to this kind of growth.
True Blue Pro Wash serves Newark and the surrounding neighborhoods including Pike Creek, Christiana, and communities right along Route 2 and the University of Delaware corridor. We have been cleaning houses in this area long enough to know that a standard pressure washer aimed at vinyl siding, EIFS stucco, or older wood is a recipe for water intrusion, broken seals around windows, and cracked panels. That is why we use soft washing for every house exterior job we take on. Soft washing means we apply a low-pressure, biodegradable cleaning solution that kills the biological matter at the root rather than blasting the surface and leaving the problem to grow back in a few weeks.
Why Newark Homes Need Soft Washing Every One to Two Years
Newark's climate does not do your siding any favors. From late April through June, pollen from the tree canopy coats every horizontal surface and sticks to the siding along with dust and moisture. By August, that film has turned into a food source for algae and mildew. Then the freeze-thaw cycles in December and January drive any moisture that has worked its way behind dirty or degraded siding even deeper. Regular soft washing breaks that cycle before it can cause real damage.
- Green algae on north and shaded west-facing walls, common in Pike Creek's heavily wooded lots
- Black or gray mildew streaks on vinyl siding near ground level and under overhangs
- Heavy pollen and dust film in late spring, especially along Route 896 and Paper Mill Road corridors
- Oxidation and chalking on older painted surfaces that makes dirt stick even faster
- Efflorescence and biological staining on brick and block foundations
How Our House Soft Washing Process Works
When we show up at a home in Newark, whether it is a townhouse near the University of Delaware, a colonial in Pike Creek, or a rancher out in the Christiana area, we start with a walkthrough. We check for any loose caulk around windows and doors, note the siding type, and look at the grade of the lot so we know which way runoff will flow when we rinse. Then we wet down any plantings close to the foundation and cover anything that needs protecting.
We apply our cleaning solution from the bottom up to avoid streaking, let it dwell for the right amount of time based on how heavy the growth is, and then rinse thoroughly from the top down at low pressure. The result is siding that looks close to what it looked like the day it was installed, without any of the risk that comes with high-pressure cleaning. The cleaning solution we use is biodegradable and breaks down quickly once it hits the ground and rinse water, so it is safe for your landscaping and your pets.

What Soft Washing Does Not Cover and What to Add On
House soft washing takes care of the walls, soffits, and fascia boards, but it is not the same as a full-property exterior cleaning. A lot of our Newark customers add on driveway and sidewalk pressure washing at the same visit because the concrete around their home has the same pollen, algae, and tire-stain buildup as the siding. If your gutters are overflowing or showing dark streaks down the face, we also offer gutter cleaning and brightening as an add-on service. Getting everything done in one visit keeps the scheduling simple and usually saves you a bit compared to booking separate trips.
If your roof has dark streaks running down from the ridge, that is a separate issue called Gloeocapsa magma, a type of algae that feeds on the limestone filler in asphalt shingles. Roof soft washing addresses that problem and can add years to the life of your shingles. We handle roof soft washing separately from house washing because the approach, the solution mix, and the safety requirements are different, but it is easy to schedule both services back to back.
What to Expect After Your House Is Washed
Right after the job is done, the biggest thing you will notice is how much brighter your siding looks in daylight. Colors that looked faded or dingy usually turn out to just be dirty. The cleaned surface also sheds water and dust more efficiently in the weeks that follow, so it does not re-soil as fast. Most homes in the Newark area that we wash annually or every other year stay noticeably cleaner between visits compared to homes that go three or four years between cleanings.
We back our work with a straightforward satisfaction guarantee. If you see any area we missed or that does not look right after the job is done, call us and we come back and make it right. No runaround. That commitment is part of why we get a lot of repeat business from homeowners in Pike Creek and Christiana who first hired us for a one-time cleaning and ended up putting us on an annual schedule.

Frequently Asked Questions
How is soft washing different from pressure washing for a house exterior?
Soft washing uses a low-pressure rinse combined with a biodegradable cleaning solution that kills algae, mildew, and mold biologically. Standard pressure washing uses high-pressure water alone, which can crack vinyl panels, force water behind siding, and strip paint or caulk. For house exteriors in Newark, soft washing is the correct method and the one we use on every job.
How often should I have my house soft washed in the Newark, DE area?
Most homes in the 19711 and 19713 zip codes benefit from soft washing every one to two years. Homes with significant tree cover, shaded north-facing walls, or proximity to wooded areas like White Clay Creek tend to see growth return faster and may need annual service. We can give you a realistic recommendation when we do your initial walkthrough.
Will the cleaning solution hurt my landscaping or my pets?
We take precautions before every job by wetting down plantings and covering anything sensitive near the foundation. The biodegradable solutions we use break down quickly once diluted with rinse water. We ask that pets be kept indoors or away from the work area during the job and for about an hour after. Once the surface has dried and the rinse water has dissipated, the area is safe.
Can you wash just one side of the house if that is the only problem area?
Yes, we can focus on specific elevations if the rest of the house is in good shape. That said, biological growth on one side of a house often means early-stage growth elsewhere that you may not have noticed yet. We will walk the full perimeter and give you an honest assessment so you can decide what makes the most sense for your budget.
Do I need to be home when the job is done?
You do not need to be present as long as we have access to an outdoor water spigot and you have let us know about any areas to avoid or any pets that might be outside. Many of our Newark-area customers leave us a hose bib access code or leave the spigot unlocked and go about their day. We send a completion message when we are done.
Does True Blue Pro Wash serve addresses outside the Newark city limits in the 19711 or 19713 zip codes?
Yes. We serve the full 19711 and 19713 zip code areas, which include communities well outside the city limits such as Pike Creek, Christiana, and areas along Kirkwood Highway and Route 40. If you are unsure, call us at (302) 757-9755 and we will confirm your address is in our service area before you book anything.
