Bethlehem is the largest city in the Lehigh Valley that we serve, and its rich history as a steel town has left behind an incredible mix of architecture. From the historic row homes on the South Side to the Victorian-era properties near downtown and the newer suburban developments spreading through west Bethlehem, every neighborhood has its own character. Between the Lehigh River valley humidity and the mature tree canopy across these established neighborhoods, exterior surfaces collect algae, mold, and mildew faster than most homeowners expect.

That buildup is not just cosmetic. It can shorten the life of your siding and create slippery surfaces around your home. The good news is, it is exactly what our team takes care of every day. We serve all Bethlehem zip codes including 18015, 18016, 18017, 18018, and 18020, covering Fountain Hill, Butztown, and Freemansburg. We also serve nearby areas including Forks Township, Easton, Hellertown, Northampton, Coopersburg, and Center Valley.

Our house washing approach uses a detergent-based cleaning method rather than high pressure. That distinction matters.

Traditional pressure washing can crack siding, force water behind surfaces, disrupt window seals, and even void manufacturer warranties. Proper house washing is a process, not just equipment. It is about treating the surface, not blasting it.

We apply professional-grade cleaning solutions that break down dirt and organic growth while killing mold, algae, and mildew at the source. Because the growth is treated at the root, most homes stay clean for 2 to 3 years rather than needing to be washed every season.

Every house wash includes siding, trim, windows, screens, and the exterior face of gutters, and our team handles everything from start to finish. We also offer roof washing and gutter cleaning throughout Bethlehem and the greater Lehigh Valley.

Our Process

Inspection

Before we touch anything, we walk the entire property together. We look at every surface, note what kind of staining or growth is present, and flag any areas that need extra care. This is where we plan the best approach for your specific home.

Detergent Application

We apply our detergent to all siding, trim, windows, screens, and the outside face of gutters. The solution works into every corner, behind shutters, and along edges where growth likes to hide. We also protect all plants around the home during this step.

Dwell Time

This is where the magic happens. The detergent penetrates into the surface and kills mold, algae, and mildew at the root, not just on top. That deeper clean is what keeps your home looking great longer between washes.

Low-Pressure Rinse

We rinse everything thoroughly with gentle, controlled pressure. Because the detergent already did the hard work, we do not need to blast anything. Your siding, paint, and windows stay completely safe.

Final Walkthrough

We walk the property one more time to make sure every surface looks the way it should. If something does not look right, we take care of it before we leave. We want you to feel great about the results.

Is Your Insurance Company Asking About Your Roof?

You are not alone. Insurance companies across the Lehigh Valley are looking more closely at roof condition, and algae, moss, or lichen growth can raise red flags during inspections or policy renewals. A professional roof washing is one of the most affordable ways to keep your roof in good standing and avoid issues with your coverage. Pressure should never be used on a roof since it damages shingles and can void your warranty. Our process uses a low-pressure detergent application that kills all growth safely, with no pressure on the shingles at all.

Frequently Asked Questions

Absolutely. The South Side row homes and the Victorian-era properties near downtown need gentle handling, and our detergent-based approach is built for it. Low pressure combined with a professional cleaning solution lifts grime and kills algae without risking mortar, trim, or the older wood elements you see on homes along New Street and Wyandotte.
Most homes across Bethlehem look great for two to three years after a soft wash. Properties in west Bethlehem with heavier tree canopy or homes on the lower-lying lots near the Lehigh River can show growth a little sooner on shaded sides. Fountain Hill and Freemansburg homes generally follow the same cadence.
Yes, and it is the right method for both. Stucco can be damaged by high pressure, and older brick from the steel-era homes is porous enough that pressure can push water into the mortar joints. Our detergent soaks in, kills growth, and rinses clean with a gentle low-pressure rinse that preserves the material.
We cover all of Bethlehem and the surrounding boroughs and neighborhoods, including Fountain Hill, Butztown, Freemansburg, Hanover Township, and Lower Saucon. Our team also serves Bath, Nazareth, Hellertown, Easton, and all of Northampton County, plus parts of Lehigh County.
A standard house wash removes algae, mold, mildew, dirt, and grime. It will not remove permanent siding oxidation, rust streaks under window sills, or heavy staining from ivy or old paint. Gutter brightening, which removes the black oxidation striping on older Bethlehem gutters, is a separate service we can quote alongside the wash.
Because the row homes share close property lines, we usually need about 15 to 20 feet of curb space for our truck. Turn on your outdoor water, close windows and doors, and bring in porch decorations and small items. If you share a back alley with neighbors, a quick heads-up to them is appreciated.
