Owning a lake home in South Haven means blue-sky summers, quick-changing weather, and a few extra maintenance to-dos that protect your investment. If you have ever wondered what to handle each season, you are not alone. A clear, local checklist helps you prevent costly surprises, keep humidity under control, and safeguard docks and shorelines. Use this guide to plan your year, decide what to DIY, and know when to bring in trusted pros. Let’s dive in.
Why South Haven’s lake climate matters
South Haven sits on Lake Michigan, where lake-effect weather, strong winds, and freeze-thaw cycles can speed up exterior wear and tear. Water levels can swing year to year, changing shoreline conditions and dock needs. Summer humidity can raise the risk of mold and mildew indoors. A seasonal plan tailored to the lake will keep your home comfortable and resilient.
Spring checklist
Owner to-dos
- Walk the exterior after snowmelt. Clear gutters and downspouts, and confirm that water flows away from the foundation.
- Scan the roof and attic for missing shingles, ice-dam staining, or poor ventilation. Note issues to review with a roofer.
- Change HVAC filters and clear condensate drains. Turn on dehumidifiers in lower levels before the first humid spell.
- Inspect docks, lifts, and moorings. Tighten hardware, check floats, replace worn lines, and confirm bumpers.
- Check septic use records. If you are near the 3–5 year mark, schedule a pump-out and visual check.
- Prune winter damage and re-establish native shoreline plants to stabilize soil. Avoid heavy equipment near the waterline without proper approvals.
Call a pro when
- You see roof damage, attic moisture, or signs of ice-dam leaks.
- Dock pilings are loose, floats are degraded, or shore-power shows corrosion or GFCI trips.
- Septic alarms sound, drains gurgle, or you smell sewage.
Summer checklist
Owner to-dos
- Keep gutters, decks, and dock surfaces clean. Rinse away mineral buildup on metal and painted finishes.
- Monitor indoor humidity and aim for about 30 to 50 percent. Use dehumidifiers in basements and closed rooms.
- Inspect boat lifts and dock fasteners monthly. Replace worn cleats and lines and verify safe shore-power use.
- Look for pests such as carpenter ants or wasps. Seal small entry points.
Call a pro when
- Shore-power needs inspection or upgrades, or GFCI protection is missing.
- Persistent indoor moisture or musty odors continue despite ventilation and dehumidification.
Fall checklist
Owner to-dos
- Winterize plumbing. Disconnect and drain outdoor hoses and irrigation. Insulate exposed pipes.
- Service the furnace and confirm dehumidifier or humidifier settings for shoulder seasons.
- Decide on your dock plan for ice season. Remove, raise, or secure per local practice to reduce ice damage.
- Secure furniture and grills. Trim branches that could break under wind or snow.
- Test sump pumps, battery backups, and generators.
Call a pro when
- You need help winterizing a seasonal property’s interior plumbing and water heater.
- You plan to alter docks, lifts, or shoreline structures that could require permits.
Winter checklist
Owner to-dos
- Keep an eye on interior humidity to prevent window condensation and mold. Run fans and dehumidifiers if needed.
- Watch for ice dams and heavy roof snow. Clear safely from the ground where possible.
- Confirm stored boats, lifts, and dock sections are supported and protected from shifting ice.
Call a pro when
- Roof snow loads look heavy or ice dams form. Do not climb on icy roofs.
- You see structural movement, shoreline slumping, or seawall distress.
Waterfront systems: docks, lifts, and shorelines
Ice movement, high winds, and storms are the usual suspects behind dock and lift damage. Many Michigan owners remove docks or raise them before winter to cut risk. For seasonal practices, consult neighbors and local marinas, and review the Michigan DNR dock and boating guidance for safety and maintenance best practices.
- Use corrosion-resistant hardware designed for marine exposure and check fasteners regularly.
- Inspect flotation, rollers, and lift cables at the start and midpoint of the season.
- Confirm shore-power connections are outdoor or marine rated and include GFCI protection. Have a licensed electrician handle testing and repairs.
If you plan work at or below the ordinary high-water mark, check Michigan EGLE shoreline permits early. Some projects also require U.S. Army Corps of Engineers permit review.

Protect your home’s exterior and systems
Lakefront exposure increases wear on paints, stains, sealants, and caulking because of wind-driven moisture, sun, and freeze-thaw. Plan regular inspections and touch-ups, and use high-quality exterior coatings for longer life. For materials and fasteners, consult the NAHB guidance on coastal and waterfront materials to select corrosion-resistant options that match your environment.
Moisture control is essential in lakeshore basements and crawl spaces. Keep indoor relative humidity between about 30 and 50 percent and service dehumidifiers and HVAC coils seasonally. For setup tips and performance, review the Energy Saver guidance on dehumidifiers.
Storm readiness and flood basics
Lake-effect storms can bring high winds, heavy snow, and fast-changing conditions. A basic plan helps you respond quickly and limit damage.
- Create a storm checklist that covers loose-item storage, dock and boat adjustments, and window and garage-door reinforcement.
- Keep an updated list of emergency contractors and confirm who handles after-hours calls.
- Document damage with photos and dates after any event and take steps to prevent further damage.
If your home is in or near a mapped flood zone, lenders may require flood insurance. Even outside these areas, a policy can be a prudent layer of protection. Check your address at the FEMA Flood Map Service Center and discuss options with your insurance professional.
Permits and timing in 49090
Permitting and contractor schedules can affect when shoreline and structural work happens. Plan ahead.

- Confirm local ordinances with the City of South Haven and Van Buren County for any harbor or zoning rules.
- Build in lead time for reviews and for marina or contractor backlogs during peak seasons.

Should I remove my dock for winter on Lake Michigan near South Haven?
- Local practice varies, but many owners remove or raise docks to reduce ice damage. Ask nearby marinas and neighbors about what works on your stretch of shore.
How often should I service HVAC and dehumidifiers in a South Haven lake home?
- Schedule at least annual HVAC service and check dehumidifiers more often during humid months. Keep indoor humidity around 30 to 50 percent.
Is salt spray from Lake Michigan a corrosion risk for South Haven homes?
- Lake Michigan is freshwater, but waterfront homes still see faster corrosion from humidity, minerals, and winter road salt. Choose corrosion-resistant hardware and clean regularly.
Do South Haven lake homes need flood insurance?
