By the time you can see the algae from the driveway, it has already been eating at your siding for a full season.
That is the trap most lake home owners along the southwest Michigan shoreline fall into. The property looks fine in October. It looks rough in May. And the call to get it cleaned lands right in the middle of the most overbooked stretch of our entire year.
Fall along Harbor Country is the right moment to break that cycle. The summer guests are gone, you have had a full season to see what held up and what did not, and next year’s May through July rush is far enough away that you can get on an annual maintenance plan before everyone else is scrambling for the same narrow window of good weather. That window is open right now. It will not be in April.
Quick Answer: Double A Power Washing’s Annual Maintenance Plan lets Harbor Country and Michiana lake home owners schedule exterior cleaning services at a set cadence, lock in priority spring booking, and avoid paying reactive rates when algae or grime has already taken hold.
Key Takeaways
- Algae and organic growth on siding and decks are already established long before they become visible from the driveway
- Plan members lock in priority spring scheduling before the May through July rush fills the calendar
- A scheduled service costs less per visit than a reactive call placed when a problem is already overdue
- The plan covers the services that matter most at a lake home: house wash, roof, deck, concrete, gutters, and more
- Fall is the best window to get on next year’s calendar before Harbor Country demand spikes

What Happens to a Lake Home Exterior When Nobody Is Watching
A lake home in New Buffalo or Union Pier sits empty for stretches of time that a house in town never does. That is part of the appeal. It also means the exterior accumulates months of biological growth with no one around to notice it.
The southwest Michigan shoreline runs humid and shaded in ways that accelerate exactly the organisms that degrade exterior surfaces. Vinyl siding collects green algae and mold spores that feed on the film of pollen and organic dust settling on every surface during spring and summer. Composite decking develops black spots where moisture has sat long enough for algae to take hold in the texture of the boards.
Composite and vinyl deck surfaces are engineered to resist rot. They are not designed to clean themselves. Manufacturers specifically recommend periodic professional cleaning to protect the surface warranty.
Roof shingles pick up Gloeocapsa magma, the organism that travels on airborne spores and colonizes asphalt granules with a dark streak. It holds moisture against the shingle surface and gradually degrades granule adhesion over years. By the time you can read those dark streaks from the ground, the organism has been established for twelve to eighteen months.
Gutters along the tree lines common throughout Harbor Country fill with debris across two or three seasons. Clogged gutters push water back against fascia board, overflow against siding, and in a Michiana winter create ice dam conditions that force water under roofing materials.
None of this is dramatic until it is. A scheduled annual maintenance plan keeps all of it from compounding.
Why the May Through July Window Is the Problem
Every lake home owner on the southwest Michigan shoreline wants their property cleaned in May before Memorial Day, or in early June before the first real stretch of summer guests. That window is real, it is short, and it is the same for everyone on the shoreline.
When you call in late April because you just drove out and noticed the siding looks rough, you are calling at the same time as every other lake home owner who made the same discovery on the same weekend. Reactive calls in that window back up fast. Some never get fit in before the Fourth of July.
Plan members get priority scheduling. When we open the spring calendar in March, plan members claim their dates before the open slots fill with reactive calls. If your house wash and deck cleaning are already on the books for the third week of May, you are not making a frantic call in late April hoping someone fits you in.
For a lot of lake home owners coordinating a property from two states away, that certainty is worth as much as the cleaning itself.
Pro Tip: When you close up for the season, do a quick walk around the exterior and note anything that looked worse than last year. That list is the starting point for building your plan. Algae on the north side of the siding, streaking on the roof near the ridge, or a composite deck with black spotting all have different causes and different service timelines.
What Our Annual Maintenance Plan Actually Covers
The plan is built around the services that matter most for a lake home exterior in the Michiana region. Here is what we work through with each plan member:
- House wash soft washing. Low pressure soft wash of all siding, soffit, fascia, doors, windows, and screens. We apply a sodium hypochlorite blend, let it dwell to kill the biology at the root, and rinse from the top down. Plants get soaked with clean water before and after so nothing transfers to the landscaping.
- Roof soft washing. The only method that actually kills Gloeocapsa magma rather than just blasting it off temporarily. High pressure damages asphalt granules. Soft wash chemistry kills the organism and lets it wash off naturally over subsequent rains.
- Composite and vinyl deck cleaning. Low pressure wash to remove algae, mold, and organic staining from composite and vinyl deck surfaces. We do not clean wood decks, and we do not stain or seal any deck surface. Composite and vinyl only.
- Concrete and driveway cleaning. Surface cleaning of driveways, walkways, and patios to remove oil, organic staining, algae, and winter salt residue.
- Gutter cleaning and flushing. Clearing debris and flushing downspouts so water moves away from the foundation the way it is supposed to.
- Vinyl fence cleaning. Soft wash of vinyl fencing. Vinyl only, not wood.
Not every plan includes every service. We work through what the property actually needs, build the schedule around the right cadence for each surface, and confirm the plan before the season starts. Some surfaces need annual attention. Others can go every other year depending on the site conditions and how much tree cover and humidity the property deals with. You can read more about how the plan works on our services page.

The Real Cost Difference Between Planned and Reactive Service
Reactive service costs more per visit than scheduled service. That is true for almost every trade, and exterior cleaning is no different.
When you call because something looks bad and you need it done before the weekend, we have to work you into a calendar that is already full, often rerouting a truck. That costs more to deliver and gets priced accordingly.
A plan also prevents the compounding cost of deferred maintenance. Algae that sits on composite decking long enough to stain the surface requires more chemistry and more time to treat than algae caught early. A roof that has carried Gloeocapsa magma for two or three seasons has deeper colonization and takes longer to respond to treatment. The longer the interval between cleanings stretches, the higher the service cost climbs.
We are not going to quote you a specific number here because every property is different. The footprint matters, the surface count matters, the drive matters. What we can tell you is that plan pricing is consistently better than reactive pricing for the same services, and we give plan members an honest read on what cadence actually makes sense for their property.

DIY vs. Hiring a Pro
| Factor | DIY / Rental | Double A Power Washing |
|---|---|---|
| Scheduling | Call when it looks bad and compete for late April and May slots | Dates locked before spring demand spikes; priority access for plan members |
| Cost per service | Reactive call rates with a rush premium when the calendar is already full | Plan pricing is consistently lower than reactive rates for the same work |
| Roof cleaning method | Pressure washing strips granules and does not kill the organism | Soft wash chemistry kills Gloeocapsa magma at the root with no granule damage |
| Deck surface care | Consumer pressure washers can etch composite boards or void surface warranties | Calibrated low pressure wash matched to composite and vinyl specifications |
| Gutter clearing | Manual scooping misses downspout blockages and carries risk when done from a ladder | Debris cleared and downspouts flushed and confirmed flowing |
| Plant and landscaping safety | Mixing bleach solutions incorrectly risks runoff damage to plants | Plants soaked before and after with correct dilution applied every time |
Pro Tip: Composite and vinyl deck manufacturers commonly require documentation of periodic professional cleaning to support surface warranty claims. A maintenance plan gives you that documented service history without having to think about it.
Fall Is the Window That Most Lake Home Owners Miss
September and October along Harbor Country feel like a natural stopping point. The season is winding down, you are closing up, and exterior cleaning feels like a spring problem.
That thinking is exactly why most lake home owners end up making a reactive call in late April instead of a planned call in March.
When you reach out in fall, we can look at what the summer left behind, give you an honest read on what needs to come first next year, and get your dates on the calendar before the spring rush even exists. You are not competing with anyone for that conversation in September. By April, you are.
We serve the full Harbor Country corridor from Grand Beach and New Buffalo through Union Pier, Lakeside, and Harbert, and extend up through St. Joseph and Stevensville. We also cover the inland Michigan lake communities including Cassopolis and Edwardsburg, and the full Indiana side from Mishawaka and South Bend through the lakeshore communities at Long Beach. If your property is in this corridor, we can schedule it.
The conversation costs nothing. A free estimate by phone or through the website takes a few minutes and gives you a real picture of what the annual maintenance plan would look like for your specific property.

Frequently Asked Questions
What does an annual maintenance plan for a lake home include?
The plan is customized to each property. For a typical lake home, that means soft wash house washing, roof soft washing, composite or vinyl deck cleaning, concrete and driveway cleaning, gutter cleaning and flushing, and vinyl fence cleaning where applicable. Not every surface needs the same schedule, so we build the plan around the right cadence for each one rather than defaulting everything to once per year.
Is an annual exterior cleaning plan available for residential lake home owners?
Yes, for both residential and commercial properties. For lake home owners specifically, it is one of the most practical arrangements we offer. The property sits empty for long stretches and you are often coordinating from a distance. Having the schedule locked in before the season starts means one less thing to manage when summer arrives.
How does priority scheduling work for plan members?
When we open the spring calendar, plan members get first access to their preferred dates before we fill open slots with reactive calls. The May through July window is the most heavily booked stretch of the year along the southwest Michigan shoreline, and demand consistently exceeds available dates. Plan members do not compete for those slots with the general public. Their appointments are already on the books.
Can I add or remove services from my plan during the year?
Yes. Properties change, needs change, and we are not interested in locking anyone into services they do not need. If something turns out to be unnecessary or you want to add a service that was not in the original plan, we work that out when it comes up. The plan is a framework for staying ahead of the work, not a rigid contract.
Why is a maintenance plan better than calling for service only when something looks bad?
Because visible deterioration means the biology has already been established for a full season or more. Algae on siding, dark streaks on a roof, and organic buildup on composite decking all cost more to treat the longer they sit, in both chemistry and time on the job. Planned service catches these things earlier, costs less per visit, and protects the surfaces from the compounding damage that deferred maintenance allows. For a lake home that sits unoccupied for months at a time, that early catch is especially valuable.
You have had a full season to see what the shoreline did to your property. Now is the time to do something about it before April gets here and every other lake home owner on the corridor has the same idea on the same weekend.
