Deep in the Lowcountry, high humidity and heavy rainfall keep organic growth working on Summerville home exteriors year-round. That green and black film spreading across your siding is not just dirt; it is living algae and mildew, what we call organics, and it thrives on untreated siding. With so many area homes backing up to ponds and standing water, the ones nearest the water tend to soil even faster.
The good news is that this kind of growth does not need a blast of high pressure to remove. We soft wash Summerville homes with a gentle, low-pressure approach that safely lifts algae, mildew, and dirt off your siding, and every job at Holy City Hydroshine includes extensive plant and property protection so your landscaping is looked after from start to finish.
If your siding has started to green up, we are glad to take a look and give you a straight answer on what it needs. Call us at (843) 729-3095 to get started.
We adjust the soft-wash approach to the material your home is clad in, so the cleaning is matched to the surface.
Vinyl is the most common siding on homes around here, and it is the surface the region’s humidity-driven algae and mildew tend to hit hardest. Its smooth face responds well to a gentle soft wash, coming back clean without a drop of high pressure.
Fiber-cement plank gets the same gentle treatment, with no high pressure that could work behind the boards. The solution does the cleaning, and the surface is rinsed clean.
Stucco is soft washed at a slightly higher solution concentration when heavy organics call for it. We work the growth off the textured surface carefully. Because stucco takes more product and time, it carries a pricing surcharge (see Pricing below).
Brick is soft washed to remove algae, mildew, and dirt without blasting the mortar joints. We reach for a higher-concentration solution only where organics are heavy, the same careful approach we bring to driveway and concrete cleaning on the hard surfaces around your home. Like stucco, brick carries a pricing surcharge.
On a painted home we test-spot an inconspicuous area first to see how the surface responds, then soft wash at the gentlest effective concentration. Sodium hypochlorite is an oxidizer, but at the right concentration it cleans painted siding without harming it.
A house wash should leave your home clean without costing you your plants or your paint. Here is what sets our work apart.
Your landscaping is an investment, and we treat it that way on every wash. We wet down plants, cover doorbells, electronics, and fixtures, and apply a neutralizer afterward so nothing is left to burn your landscaping and the yard you’ve put years into comes through the clean untouched.
Rather than blasting your siding with a pressure washer, we downstream a low-concentration sodium hypochlorite solution at low pressure. The chemistry lifts algae, mildew, and dirt while the gentle pressure protects vinyl, Hardie plank, stucco, brick, and paint alike.
Before any full application on a painted home, we test-spot a hidden area to confirm how the surface reacts, so you get a careful, tailored clean. It is standard on every painted-siding job and included at no extra cost.
Our crew is PWNA-trained, so the people cleaning your home understand the chemistry and the method behind doing it safely on each siding type. That training is what turns a good result into a consistent one, job after job.
Instead of hiring a separate window company, a gutter company, and a pressure washer, you get it all done in one visit, by one company, with one bill, while we are already on site. If you want the windows cleaned, gutters, or driveway handled too, we can knock them out the same day.
From the first call to the final walkaround, here is exactly how a house wash goes.
You reach out by phone or online, and we provide a free estimate, in person or instantly online, covering the scope, your siding type, and what to expect. If your home is painted, we note it up front for test-spotting.
Once you approve the estimate, we schedule the job and send confirmation and reminders leading up to the appointment, plus a note the morning of with an ETA. You will never be left wondering when we are coming.
When we arrive we do a pre-wash inspection and take before photos. Then comes full plant and property protection, plants wetted down and doorbells and electronics covered, before any solution touches the house. Painted surfaces are test-spotted first.
We downstream a low-concentration sodium hypochlorite solution, stepping it up only on heavy organics or stucco, using the downstream injector on our cold water unit and our soft wash system. We work one side of the home at a time, let the solution dwell, then rinse. The pressure stays low throughout, because it is the chemistry that lifts the organics. Pump sprayers handle any spots that need a closer touch.
Afterward we apply a neutralizer so nothing is left behind to harm your landscaping, then do a post-wash inspection and take after photos. Those go straight to you, along with a link to leave a review if you are happy with the result.
Before a single piece of equipment gets packed up, we walk the finished job with you. We do not consider the wash done until you have seen it and you are satisfied with how your home looks.
Most house washes are priced by the home’s square footage, with the final figure depending on the size of the home and the siding material. The business-wide $300 minimum applies, and most residential customers spend between $500 and $1,000 depending on the package they choose.
A few standing discounts apply when house washing is part of a larger job:
For anything that is not a standing offer, just ask when you get your estimate.
No, we do not call it bleach, and the professional product we use is sodium hypochlorite applied at a low concentration, around 1 to 1.25% on a typical house wash. It is the same active ingredient found in pool shock, and at a tiny dosage even in eye drops, so it comes down to the concentration applied, not the name on the jug. At that strength it clears algae and mildew from your siding while your plants and landscaping stay protected the whole time we are on site.
No, you do not need to be home. We document the whole job with before-and-after photos and send them to you whether or not you are there. If you are home, we will walk the finished job with you before we pack up.
It depends on the home, how much shade it gets, how close it sits to a pond or water, and how quickly organics return in the Lowcountry’s humidity. That same growth tends to settle on the roof, which is why many homeowners pair a wash with periodic roof cleaning. Homes in heavy shade or near water tend to need it more often, and we will give you an honest read at the estimate rather than push you into a set schedule.
A standard vinyl-siding home typically takes about 1 to 1.5 hours. Larger homes, or stucco and brick that call for a higher solution concentration, take a bit longer.
Whatever your siding is up against this season, we will give you a straight read on what your home needs and what it will cost, with a free estimate and no obligation. Call us at (843) 729-3095 and we will get your Summerville home back to looking its best.
