Top-Rated Roof Cleaning &
Power Washing
in
New Haven, IN
M&D Power Washing provides professional exterior cleaning services in New Haven and East Allen County. We clean roofs, siding, driveways, and gutters using the safest method for your specific property.
We understand that living near the SR-930 corridor and active railways brings extra dust and road grime to your siding. We bring over 20 years of exterior cleaning expertise to the 46774 area, ensuring your property looks well-maintained and welcoming.
Protecting East Allen County Homes from Algae & Weathering
Maintaining a home in the 46774 zip code requires more than just high pressure. New Haven’s mix of historic properties near downtown and newer subdivisions along the I-469 loop demand a careful, tailored approach.
We specialize in removing the stubborn “bio-film” often found in the Maumee River valley—a sticky combination of humidity and organic growth that standard rinsing cannot remove. Our team uses a dedicated soft wash system to dissolve these stains chemically, ensuring a deep clean that protects your siding, trim, and landscaping from damage.
Safe Soft Washing vs. High Pressure: Why New Haven Homes Need a Gentle Touch
At M&D Power Washing, we specialize in low-pressure exterior cleaning and roof-safe soft wash techniques designed to remove algae, mold, and organic staining without harming your shingles or siding. Our roof cleaning approach follows asphalt shingle manufacturer recommendations, including ARMA guidance against high-pressure washing, to protect roofing materials from unnecessary damage.
We use safe, manufacturer-recommended cleaning solutions to gently remove grime and help prevent surface wear or water intrusion. We also take extra care to protect your landscaping by rinsing plants and surrounding areas before, during, and after the cleaning process.
- Precision Chemical Blending: We don't guess. We use a dedicated manifold system to dial in the exact ratio of cleansers needed for your specific stain—whether it's heavy moss on a north-facing roof or light dust on vinyl. This kills organic growth at the root instead of just blasting off the top layer.
- Landscape Protection Protocol: We know New Haven homeowners take pride in their gardens. Our team pre-soaks and continuously rinses all plants, grass, and bushes with fresh water before, during, and after the cleaning process to ensure zero chemical burn.
- Professional Grade Equipment: Our trucks are equipped with 200ft of agricultural-grade hose and specialized soft wash tips. This allows us to clean high peaks and distant corners of your property safely from the ground or a ladder, keeping consistent low pressure (under 80 PSI) across the entire job.
Why New Haven Homes Struggle with Algae & "Country Dust"
The Maumee Valley Influence: Humidity Meets Agriculture
Unlike the dense urban shield of central Fort Wayne, New Haven properties face a unique set of environmental factors. Situated in the Maumee River valley, the 46774 zip code experiences distinct humidity levels that linger in the morning air.
Furthermore, the proximity to open farmland in East Allen County exposes homes to windblown soil, pollen, and agricultural dust. According to Purdue University Extension, windbreaks and landscaping can capture some particulate matter, but much of it adheres to vinyl siding, creating a nutrient-rich “bio-film” that feeds mold and algae growth faster than in other areas.
Understanding the Biology of Stains on Your Roof
The black streaks you see on roofs in Tudor Branch or near the 469 loop are a living bacteria called Gloeocapsa Magma.
This bacteria feeds on the limestone filler found in modern asphalt shingles. As noted by the Asphalt Roofing Manufacturers Association (ARMA), these organisms create a hard outer shell that protects them from UV rays, which causes the dark streaking.
In New Haven’s environment, agricultural dust settles on the roof, providing an extra food source that allows this bacteria to spread rapidly across the north face of your home.
The M&D Solution for Rural & Suburban Settings
Standard pressure washing often fails here because it only blasts away the top layer of dust, leaving the root system of the algae intact.
Our soft washing system treats the problem chemically. We apply a sanitizing solution that penetrates the bio-film and neutralizes the bacteria at the root. This is critical for New Haven homes, as it ensures the siding and roof stay clean for years, not just months, despite the surrounding agricultural environment.
Recent New Haven Restoration Projects: Local Success Stories
We are proud to serve homeowners throughout New Haven and East Allen County. Here are a few recent examples of our work right here in the community:

Roof Cleaning in Havenwood Subdivision
The Challenge: A two-story home in the Havenwood neighborhood was facing an issue common to East Allen County: black streaks (Gloeocapsa Magma) spreading across the roof. The homeowners were preparing to sell and worried the stained roof would scare off buyers.
The Solution: We treated the asphalt shingles with our specialized algaecide blend. This zero-pressure treatment killed the bacterial spores at the root level, removing the black streaks instantly without damaging the granule surface of the shingles.
The Result: The roof looked brand new in less than an afternoon. The homeowners passed their inspection with flying colors, and the property sold shortly after.

House Wash & Siding Refresh near Moeller Road
The Challenge: A ranch-style home near Moeller Road had developed a heavy layer of "country dust" and green algae on the north-facing vinyl. The homeowner was concerned that high pressure would crack the aging siding or force water behind the panels.
The Solution: We utilized our soft wash method to gently apply a biodegradable cleanser. This broke down the organic "bio-film" and lifted the dust without the need for abrasive scrubbing. We also protected the mature landscaping around the foundation by keeping it saturated with fresh water.
The Result: The siding was restored to a bright, crisp white, and the green algae was completely neutralized. The home looked freshly painted, boosting its curb appeal instantly.

Deck Cleaning in Rose Ave Neighborhood
The Challenge: A large treated lumber deck behind a home near Rose Ave had turned completely gray and slippery due to years of UV exposure and algae growth. The homeowners wanted to stain it but knew they couldn't apply new finish over the "dead" wood fibers and grime.
The Solution: We used a two-step wood restoration process. First, we applied a specialized wood cleaner to lift the gray oxidation and kill the algae. Then, we used low pressure (under 800 PSI) to rinse the wood, followed by a brightening agent to restore the lumber's original pH balance and golden color.
The Result:The gray sludge washed away, revealing fresh, clean wood that was safe to walk on and perfectly prepped for a new stain.
Our 3-Year Algae-Free Warranty for New Haven Homeowners
We don’t just “wash” your roof; we treat it. Because we use manufacturer-recommended low-pressure cleaning methods that effectively remove organic growth, we are confident in the longevity of our results.
If those unsightly black streaks return to your roof within three years of our professional service, M&D Power Washing will return and re-clean the affected areas at zero cost to you.

- Safe and Proven: Our guarantee is backed by a process that is gentle on shingles and safe for your New Haven landscaping.
- Fully Insured & Licensed: Your peace of mind is further secured by our $3 Million in liability coverage for every job in East Allen County.

We had M&D Power Washing in the past and then had someone else powerwash our house, which was a mistake. This year we went back to M&D and we are so glad we did!! Mark is so dedicated to being professional and he does such a good job! We have a yellow home on a lake and is basically was shining when he left. He rinses the house, sprays a chemical on it, and then sprays it down. He takes time to get all the dirt off the house. There is a two year warranty on the work. I have recommended M&D to some friends and will continue to do so. Mark is a great person to work with!!!Posted on Google![]()

Frequently Asked Questions – New Haven Exterior Cleaning
Everything you need to know about our exterior cleaning services.
How often should I wash my house in New Haven?
Because New Haven is surrounded by more open agricultural land than central Fort Wayne, we often see faster accumulation of dust and pollen on siding. For most homes in the 46774 zip code, we recommend a House Wash every 12 to 18 months. If you live near a harvested field or a gravel road, you might need an annual rinse to keep the "country dust" from bonding to your vinyl.
Is soft washing safe for older farmhouses or historic homes?
Absolutely. Many older homes in New Haven feature delicate materials like painted wood clapboard or older aluminum siding. Our soft wash method relies on chemistry, not pressure, so there is zero risk of chipping paint, denting aluminum, or forcing water into the wall cavities of historic structures.
Will cleaning remove the black streaks on my roof?
Yes. Those black streaks are a bacteria (Gloeocapsa Magma) that thrives in Indiana's humid climate. Our treatment kills the bacteria at the root and removes the stains instantly. We offer a 3-Year Algae-Free Warranty on all roof cleanings, ensuring your home stays beautiful long after we leave.
Can you remove the orange rust stains on my siding or concrete?
Yes, but this requires a specialized treatment. Those orange stains are common in East Allen County due to high iron content in well water irrigation or fertilizer runoff. Standard pressure washing will not remove them. We use a dedicated rust-neutralizing solution that chemically lifts the iron deposits from your concrete or vinyl without damaging the surface. If you have these stains, please mention them when you call so we can bring the right treatment!
Is your cleaning process compliant with New Haven stormwater rules?
Absolutely. New Haven is an MS4 community, meaning it is illegal to discharge cleaning chemicals into storm drains. Unlike unlicensed contractors who risk fines for you, M&D Power Washing follows all local environmental protocols. We block storm drains when necessary and divert wash water to your landscaping (where it is neutralized) to ensure "Only Rain Down the Drain."
Do you service outside of New Haven city limits?
Yes! We are the go-to exterior cleaners for all of East Allen County. Our trucks are frequently in Woodburn, Monroeville, and Zulu. Whether you are in a subdivision off Green Road or on a larger property out in the county, we have the equipment to reach you.
When is the best time to schedule?
Spring is the most popular time to wash away winter grime and salt, but we clean through the late fall. Many homeowners in New Haven schedule in the fall to remove harvest dust and prepare their homes for the holiday season.
