Summer storms build fast in Washtenaw County, and by the time a downpour hits, it’s too late to find out your gutters were clogged or your foundation had a hairline crack. The good news is that most water damage is preventable. A summer home maintenance checklist covering just three or four areas of your home can be the difference between a dry basement and a flooded one.
This guide walks through the small checks worth doing this month, explains why each one matters, and outlines what to do if you already see signs of water intrusion. Whether you own a century-old home near downtown Ann Arbor or a newer build out toward Saline or Ypsilanti, the same basic principles apply: keep water moving away from your home, and catch small gaps before a storm finds them for you.
Why Summer Maintenance Matters for Water Damage Prevention
Summer weather in Michigan brings a mix of heavy rain, high humidity, and sudden storms — all conditions that put stress on a home’s drainage and moisture-control systems. Water damage prevention starts long before a storm rolls in. Homeowners who inspect their property early in the season typically catch small issues, like a loose downspout or a cracked seal, before they turn into basement flooding or structural damage.
Waiting until after a storm to check your home is a common mistake. By then, water has often already found its way into a crawlspace, a basement wall, or behind exterior siding — and repair costs climb fast once moisture reaches insulation, drywall, or flooring.
Summer Home Maintenance Checklist: What to Inspect This Week
1. Clear Gutters and Downspouts
Clogged gutters are one of the most common — and most preventable — causes of residential water damage. When leaves, seeds, and debris block a gutter system, rainwater overflows and pools right next to your foundation instead of draining away from it.
What to check:
- Gutters are free of leaves, debris, and standing water
- Downspouts extend at least 3–5 feet away from the foundation
- Gutter seams and joints aren’t leaking or pulling away from the roofline
- Water flows freely through downspouts during a light rain test
2. Check Exterior Vents and Drainage Areas
Foundation vents, crawlspace vents, and yard drainage paths all play a role in keeping water moving away from your home instead of pooling around it. A blocked vent or a low spot in the yard that collects water can quietly push moisture toward your foundation for weeks before anyone notices.
What to check:
- Vents are clear of debris, nests, or blockages
- Grading around the home slopes away from the foundation, not toward it
- Window wells are clear and draining properly
- Sump pump (if present) is tested and functioning before storm season peaks
3. Look for Foundation Cracks or Signs of Moisture
Foundation cracks — even small, hairline ones — are entry points for water once summer rains saturate the soil around your home. Regular inspection of your foundation walls, both inside and outside, helps catch problems while they’re still a simple sealing job rather than a full restoration project.
What to check:
- Hairline or widening cracks in foundation walls, especially near corners
- Damp spots, discoloration, or a musty smell in the basement
- Efflorescence (white, chalky mineral deposits) on concrete surfaces
- Peeling paint or bubbling drywall near the foundation line
Why This Matters More in Washtenaw County Summers
Ann Arbor and the surrounding Washtenaw County area see a particular pattern each summer: intense, fast-moving storms that can drop a significant amount of rain in a short window. Combined with soil that’s already saturated from spring thaw, this makes local homes especially vulnerable to basement flooding if drainage systems aren’t ready. Older homes in established neighborhoods often have aging foundation seals or gutter systems that haven’t been inspected in years, which raises the risk further.
This is also the season when many homeowners are away on vacation or simply outside less often, which means early signs of a leak or a slow foundation crack can go unnoticed for days or weeks. A quick walk-around inspection once a month during summer catches problems while they’re still small.
How These Small Checks Prevent Bigger Problems
Each of these tasks takes only a few minutes, but together they address the three main pathways water uses to enter a home: overflow from above (gutters), poor drainage at ground level (vents and grading), and structural gaps below (foundation cracks). Catching an issue in any one of these areas during a routine check is far less costly than dealing with basement flooding, saturated insulation, or mold growth after the fact.
Homeowners who build this into a seasonal habit — checking gutters, vents, and foundations each summer — typically avoid the kind of emergency calls that come with storm damage, burst pipes, or sewage backups later in the year. Left unaddressed, even a minor leak can lead to warped flooring, damaged drywall, and mold growth within 24 to 48 hours of water intrusion, which is why early detection matters so much more than the size of the initial problem.
Other Summer Trouble Spots Worth a Quick Look
Beyond gutters, vents, and foundation walls, a few other areas tend to cause trouble once summer heat and storms arrive:
- AC condensation lines: A clogged condensation line can leak steadily into a ceiling or wall cavity for weeks without an obvious drip. Check that the line drains freely and isn’t backing up.
- Sprinkler and irrigation systems: A cracked line or a sprinkler head aimed too close to the foundation can saturate soil right where you don’t want extra moisture.
- Window wells and exterior seals: Caulking around basement windows and exterior door frames dries out and cracks over time, creating small gaps where wind-driven rain can get in during a storm.
- Roof flashing: Areas where the roof meets a chimney, skylight, or vent pipe are common spots for flashing to loosen after a Michigan winter. A quick visual check from the ground can catch obvious gaps.
None of these take more than a few minutes to check, and each one closes off another path water could use to get inside.
When to Call a Professional Restoration Company
Some signs of water intrusion call for more than a DIY fix. If you notice any of the following, it’s time to bring in a professional rather than waiting to see if it gets worse:
- Standing water in a basement or crawlspace
- A musty or mildew smell that doesn’t go away with ventilation
- Visible mold growth on walls, ceilings, or flooring
- Warped flooring, bubbling paint, or sagging ceiling tiles
- A foundation crack that’s widening or leaking during rain

Frequently Asked Questions
How often should I check my gutters in the summer? A good rule of thumb is once a month during summer, and after any major storm. Trees near your roofline may need more frequent checks since they shed debris throughout the season.
Are small foundation cracks really a problem? Yes. Even hairline cracks can widen over time and allow water to seep in during heavy rain, especially when soil around the foundation is saturated. It’s worth having any crack evaluated if it’s new or appears to be growing.
What’s the difference between water damage and flood cleanup? Water damage generally refers to moisture intrusion from a single source, like a leak or overflow, while flood cleanup typically involves larger volumes of water from storms, sewage backups, or burst infrastructure. Both require prompt drying and moisture remediation to prevent mold.
Can I prevent basement flooding without a sump pump? A sump pump is one of the most effective tools for basement flooding prevention, but proper grading, clear gutters, and sealed foundation cracks all reduce risk even without one. Homes prone to water intrusion benefit most from combining several of these measures.
When should I call a water damage restoration company instead of handling it myself? Call a professional as soon as you see standing water, a persistent musty smell, or visible mold. Delays allow moisture to spread into walls, flooring, and insulation, which increases both the cost and the health risks of restoration.
