Preparing Your Houston Home for Hurricane Season

Atlantic hurricane season officially runs from June 1 through November 30, and Houston sits directly in the target zone. The Houston metro area has been hit by, or significantly affected by, major tropical weather events including Hurricane Harvey (2017), Tropical Storm Imelda (2019), Hurricane Laura (2020), Hurricane Nicholas (2021), and Hurricane Beryl (2024). If you have lived in Houston for any length of time, you already know that the question is not if a storm will affect your property, but when.

While most hurricane preparation guides focus on boarding up windows, stocking water, and reviewing insurance policies, your home's exterior surfaces play a bigger role in storm resilience than most people realize. Here is how pre-season pressure washing and maintenance fits into your hurricane preparation plan.

Clean Gutters Save Homes

Gutters are your roof's primary defense against water damage, and they fail catastrophically when they are clogged. Houston's heavy tree canopy drops leaves, twigs, pine needles, and seed pods into gutters year-round. By the time hurricane season starts in June, most Houston gutters have accumulated six months of debris from spring pollen season and the live oak leaf drop in March and April.

During a tropical storm, a clogged gutter system causes water to overflow and cascade down the side of your home. That water pools around your foundation, seeps into walls, and can cause thousands of dollars in damage. We have seen Memorial and Heights homes suffer water intrusion damage from clogged gutters during storms that brought less than four inches of rain, an amount that clean gutters handle easily.

Professional gutter cleaning before June 1 is one of the highest-value investments you can make for hurricane preparedness. It takes about an hour for most homes and costs a fraction of what water damage repair runs.

Pressure Wash Before the Storm, Not After

After Harvey hit Houston in August 2017, the demand for pressure washing and exterior cleaning skyrocketed. Flood waters left behind clay sediment, sewage residue, chemical contamination, and organic debris on hundreds of thousands of properties. Wait times for cleaning crews stretched to weeks and months. Prices went up because demand far outpaced supply.

Getting your property cleaned before hurricane season accomplishes two things. First, it removes the existing mold, algae, and organic buildup that traps moisture against surfaces and accelerates storm damage. A clean surface sheds water faster and dries more quickly after a storm, which reduces the window for mold to take hold. Second, it establishes a baseline so you can accurately assess storm damage for insurance claims. If your driveway had pre-existing staining before the storm, it is harder to separate storm damage from existing wear.

Pre-Storm Exterior Maintenance Checklist

Here is a practical checklist for Houston homeowners heading into hurricane season:

• Clean all gutters and downspouts. Make sure water flows freely from roof to ground. Check that downspout extensions direct water at least 3 feet away from your foundation.
• Pressure wash the driveway and sidewalks. Remove organic buildup that traps water and creates slip hazards during storms.
• Soft wash the house exterior. Kill mold and algae on siding before the storm adds moisture that accelerates their growth.
• Clean the roof. Remove moss, algae, and debris that can trap moisture under shingles during extended rain events.
• Inspect and clean the garage floor. If your area floods, a clean garage floor is easier to sanitize and dry after water recedes.
• Clear fence lines and deck areas. Remove debris piles and organic buildup from fence bases where standing water collects.
• Document your property's condition. Take photos and video of all exterior surfaces after cleaning. This documentation is valuable for insurance claims if storm damage occurs.

Post-Storm Cleaning: Acting Fast Matters

If a storm does hit, the speed of your cleanup response makes a significant difference in long-term damage. Flood water that sits on concrete and masonry for more than 48 hours can leave permanent mineral stains as the water evaporates. Mud and silt that dry on surfaces become much harder to remove than when they are fresh. And any biological contamination from sewage overflow or bayou flooding needs to be cleaned and sanitized quickly to prevent health hazards.

We prioritize post-storm cleanup for our existing customers and offer rapid-response scheduling when tropical weather threatens the Houston area. Having a relationship with a reliable cleaning company before hurricane season means you are at the front of the line, not the back, when a storm hits.

Lessons from Harvey

Hurricane Harvey dumped over 60 inches of rain on parts of the Houston metro over four days in August 2017. It was the largest rainfall event ever recorded in the continental United States. Addicks and Barker Reservoirs overflowed for the first time in their history, flooding neighborhoods in Memorial, Katy, and Bear Creek that had never flooded before. More than 300,000 structures in the Houston area were flooded.

The aftermath revealed how unprepared many homeowners were for exterior recovery. Properties that had been well-maintained before the storm recovered faster. Clean concrete is easier to sanitize than concrete with years of organic buildup. Houses with recently cleaned siding showed less post-flood mold damage. Properties where gutters were functioning properly experienced less foundation damage from water pooling.

Harvey was a once-in-a-lifetime event, but Houston faces tropical weather threats every year. Preparing your home's exterior is as important as stocking your emergency kit.
