San Antonio's Storm Season Is No Joke
San Antonio sits in a region known for intense, fast-moving thunderstorms — particularly in spring (March–June) and fall (September–November). These storms can drop 2–3 inches of rain in under an hour, creating massive runoff from your roof.
If your gutters are clogged with leaves, pollen, and debris from the previous season, that water has nowhere to go. It overflows against your foundation, behind your fascia boards, and under your roofline — causing damage that can cost thousands to repair.
What Happens When Gutters Overflow
Foundation damage: San Antonio's clay soil expands dramatically when saturated. Repeated overflow events cause the soil around your foundation to expand and contract, leading to foundation movement, cracks, and costly repairs.
Fascia and soffit rot: When gutters overflow, water runs behind them and saturates the wooden fascia boards and soffit. This leads to rot, mold, and eventually structural damage to your roofline.
Basement and crawl space flooding: Water that pools against your foundation can seep into basement areas or crawl spaces, causing mold growth and structural damage.
Landscape erosion: Concentrated overflow from clogged gutters can erode landscaping, wash away mulch, and damage plants around your home's perimeter.
The Best Time to Clean Your Gutters in San Antonio
Spring (February–March): Clean before the spring storm season begins. This removes winter debris, oak pollen, and any buildup from fall leaf drop.
Fall (October–November): Clean after the main leaf drop from oak and pecan trees. This prepares your gutters for winter and the next spring storm season.
Homes with heavy tree coverage — especially in Stone Oak, Shavano Park, and Alamo Heights — may need cleaning 3–4 times per year.
Don't Wait Until It's Too Late
The worst time to discover your gutters are clogged is during a storm. By then, the damage is already happening. A pre-season cleaning costs $129–$200 and takes about an hour. Foundation repairs cost $5,000–$30,000.
