Leo-Cedarville, IN
M&D Power Washing helps keep Leo-Cedarville beautiful, from the historic homes near the Olde Church Shoppes to the luxury estates of Makarios Place. We understand that living near the St. Joseph River and Cedarville Reservoir brings unique challenges—specifically, the heavy green algae and moss caused by river mist and humidity. We bring over 20 years of expertise to the 46765 area, ensuring your home looks as pristine as the day it was built.
Specialized Care for Leo’s Custom & Lakefront Homes
Leo-Cedarville isn’t just standard vinyl siding. We specialize in maintaining the diverse, high-end architecture found in Northeast Allen County—from custom homes featuring Delicate Stone Veneer and Dryvit (Stucco) to historic farmhouses near Grabill.
These materials are porous and fragile. They cannot be treated with the same “blast it clean” approach used on a concrete driveway. Treating a lakefront property or a custom build requires a cleaner that understands the difference between cleaning a surface and destroying it.
M&D’s Soft Wash Difference: Why High-Pressure Power Washing Fails in Leo-Cedarville
This is why we strictly use Soft Washing for your home’s vertical surfaces and roof. High-pressure washing (3,000+ PSI) can chip the mortar off your stone veneer, force water behind your siding (leading to mold inside the walls), and strip the UV coating off vinyl.
We use a low-pressure application—about the strength of a garden hose—combined with a biodegradable cleanser. This relies on chemistry, not force, to lift dirt, dissolve spiderwebs, and kill organic growth safely without voiding your manufacturer’s warranty.
- Precision Chemical Blending: We adjust our solution to handle Leo’s specific ecosystem. We add a specialized surfactant to dissolve the sticky spiderwebs common near the reservoir, while ensuring the mix is gentle enough to clean porous stone veneer and Dryvit without causing discoloration.
- Active Plant & Landscape Satiation: We respect the local drainage. Whether you are on Cedar Creek or in a subdivision, a dedicated technician saturates your plants with fresh water before, during, and after the wash. This creates a barrier that neutralizes our cleaning agents instantly, protecting your soil and nearby waterways.
- Professional Grade Equipment: Leo properties are often larger and set further back from the road. Our 12V high-flow system allows us to clean 3-story custom peaks and detached buildings (like pole barns or boat houses) safely from the ground, without driving heavy machinery onto your manicured lawn.
Why Leo-Cedarville Homes Struggle with Algae, Mold, and Surface Decay
Local Climate Factors: The "Reservoir Microclimate"
Properties in the 46765 zip code face a unique atmospheric challenge we call the “Reservoir Effect.” Because of the Cedarville Reservoir and the winding St. Joseph River, homes here experience significantly higher morning fog and dew points than properties in downtown Fort Wayne.
In established neighborhoods like Riverside Gardens or the wooded lots off Amstutz Road, the mature tree canopy traps this river moisture against your siding. This constant dampness creates an incubator for Green Algae (Gloeocapsa Magma) and Lichen—specifically on the North and West sides of homes where the sun hits last.
The Aquatic Insect & Spider Cycle
If you live near the water in Leo, you know it isn’t just about dirt—it’s about the food chain. The reservoir breeds aquatic midges (blind mosquitoes), which attract spiders by the thousands to your eaves, soffits, and boat houses.
You cannot simply pressure wash a spider infestation. High pressure knocks down the web but leaves the sticky silk protein and egg sacs behind. Within 48 hours, the spiders return to rebuild on the existing anchors.
Beyond the webs, spider droppings (highly acidic) and bird droppings can permanently etch vinyl siding and stain stone veneer if left uncleaned.
The M&D Solution: Biological Neutralization
Standard pressure washing only “haircuts” these problems. To solve the “Leo Lake Life” issues, we use a custom-blended Soft Wash solution engineered for this specific environment.
Our cleaning formula includes a specialized surfactant that breaks down the protein bonds in spiderwebs and insect nests, allowing us to rinse them away completely without scrubbing.
By neutralizing the algae spores and removing the spider pheromones left on the siding, we reset the surface. This keeps your home cleaner 4x longer than water-only washing.
Recent Leo-Cedarville Restoration Projects: Local Success Stories
We’ve completed power washing and exterior cleaning projects throughout Leo-Cedarville and nearby communities. From siding and roofs to gutters and concrete, we handle every surface with the right method and attention to detail. Here are just a few recent examples:

Roof Restoration in Cedar Canyon Road
The Challenge: A historic farmhouse in Cedar Canyon Road had heavy moss buildup on the north-facing roof. The shade from mature trees had allowed the moss to trap moisture against the asphalt shingles, threatening to rot the decking.
The Solution: We applied our specialized 3% Soft Wash blend to kill the moss at the root without using high pressure, which could have damaged the aging granules.
The Result: The moss turned white and detached naturally within weeks, restoring the roof's function and extending its lifespan by an estimated 5 years.

Soft Wash House Cleaning & Siding Restoration near Cedarville Reservoir
The Challenge: A beautiful lakefront home was suffering from the "River Effect"—heavy green algae on the vinyl siding and thick spiderwebs on the second-story peaks.
The Solution: Using our high-reach 12V system, we applied a spider-dissolving surfactant to melt the webs and neutralize the algae. We also utilized our "Plant Protect" protocol to cover the homeowner’s prize-winning hydrangeas during the wash.
The Result: A spotless, web-free exterior ready for summer entertaining, with zero damage to the landscaping.

Residential Pavement & Concrete Restoration on Tonkel Road
The Challenge: This residential pavement in Leo-Cedarville had lost its clean appearance due to a thick layer of embedded dirt and environmental grime. Years of weather exposure had turned the bright concrete into a dull, grey surface that looked aged and neglected.
The Solution: We pre-treated the pavement to loosen the impacted soil. Then, utilizing our professional surface cleaner, we delivered a consistent, high-pressure wash across the entire area. This specialized tool is crucial for removing heavy dirt accumulation evenly, preventing the unsightly "tiger striping" lines often left by standard pressure washing wands.
The Result:The transformation was immediate. The deep-cleaning process stripped away years of grime, revealing the clean, bright pavement underneath. The surface now looks brand new, instantly boosting the property's overall appearance.
Our 3-Year Algae-Free Warranty for Leo-Cedarville Homeowners
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.

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
Everything you need to know about our exterior cleaning services in the 46765 area.
Is soft washing safe for my pets and landscaping?
Absolutely. We take environmental safety seriously, specifically when working near the Cedarville Reservoir or Cedar Creek. We use a strict "Plant Protect" protocol where a dedicated team member saturates your garden with fresh water before, during, and after the process to dilute any run-off instantly.
How long do the results last in Indiana's climate?
Our specialized soft wash kills organic growth at the root. Despite the higher humidity near the river, results typically last 3–5 years. This is why we can confidently offer our 3-Year Algae-Free Warranty to all Leo residents.
Can you clean my siding during the winter months?
While we operate primarily from March through November, we monitor weather patterns closely. If we get a warm spell in Leo where temperatures stay safely above freezing, we can perform services. Call us to check our off-season availability.
Are you licensed and insured to work in Allen County?
Yes. M&D Power Washing is fully licensed and carries $3 Million in liability insurance. Whether we are working on a residential driveway or a commercial building in Grabill, your property is completely protected.
Do you use river water or well water to clean?
No. We never use river or pond water, as it can contain contaminants and algae spores that we are trying to remove. We bring our own purified water or connect to your home's spigot, ensuring a clean, filtered wash every time.
Will the cleaning solution harm my landscaping or fish pond?
We take extreme care with properties near the water. We pre-soak all plants with fresh water and divert runoff away from sensitive areas like koi ponds or the riverbank. Our cleaning solutions are biodegradable and break down rapidly once the job is done.
Professional Solutions for Residential & Commercial Properties in Leo-Cedarville, IN
We safely remove algae, moss, and dirt to restore your property’s curb appeal instantly. Our specialized equipment is designed to handle everything from historic farmhouses to modern custom estates.
Roof Cleaning
Stop the spread of black streaks (Gloeocapsa Magma) and moss that eat away at your shingles. Our Soft Wash process uses a biodegradable treatment to kill organic growth at the root without the damage of high pressure. Backed by our 3-Year No-Streak Guarantee.
House Washing
Properties near the St. Joe River are prone to rapid green algae growth due to morning river mist. We use a safe soft-wash method to dissolve this organic buildup on vinyl, brick, and Dryvit siding, rinsing it away without forcing water behind the panels.
Concrete Cleaning
Essential for the expansive driveways found in Tullymore and Makarios. We use high-heat pressure washing to strip away heavy mud, oil, and construction dust. By deep-cleaning the pores of the concrete and removing corrosive winter salt residue, we restore the bright, clean look of your entrance and prevent the grime buildup that leads to long-term surface wear.
Cedar Roof Cleaning
Preserve the beauty and function of your wood shake roof. We use a gentle, oil-preserving cleaning solution to remove moss and lichen that trap moisture and cause rot. Ideal for the historic properties found throughout Grabill and Spencerville.
Slate Roof Cleaning
Slate requires delicate care. We never walk on slate roofs; instead, we use ladder-assist or aerial lift soft washing techniques to clean the tiles safely, preserving the integrity of your high-end roof for generations.
Deck Cleaning
For homes along the Cedarville Reservoir, keeping decks and docks clean is a constant battle against algae and spiderwebs. We safely wash wood and composite surfaces to prevent them from becoming slippery and gray.
Gutter Cleaning
Leo’s mature tree canopy can quickly clog gutters, leading to ice dams in winter. We remove debris to ensure proper flow and offer "Gutter Brightening" to scrub away the black "tiger stripe" drip marks on the exterior face.
Commercial Services
We help keep Downtown Leo businesses inviting. From cleaning storefronts near the Riverside Gardens to maintaining sidewalks and signage, we provide reliable exterior cleaning that respects your business hours.
