Houston’s humid subtropical climate brings some unique challenges when it comes to maintaining and inspecting homes. With hot summers, heavy rainfall, hurricanes, and flooding, Houston homeowners need to be proactive to protect their investment and keep their families safe. This article provides tips on how Houston’s climate impacts home inspections and maintenance.
High Humidity Means Increased Mold and Mildew Risks
Houston’s long, hot, and humid summers provide ideal conditions for mold and mildew growth inside homes. Home inspectors always check thoroughly for any signs of excess moisture or musty odors that could indicate mold or mildew problems. Homeowners need to be vigilant as well to catch issues early before they become expensive repairs.
Some tips for homeowners:
- Use exhaust fans regularly in kitchens, bathrooms, and laundry rooms to vent out moisture.
- Make sure air conditioning drip pans drain properly and are kept clean.
- Clean and disinfect humidifiers and dehumidifiers often.
- Use mold inhibiting paints and caulks, especially in wet areas like bathrooms.
- Keep an eye out for condensation and musty smells that could indicate excess moisture.
Heavy Rainfall Increases Risk of Leaks and Water Intrusion
Houston gets over 49 inches of rain per year on average. Thunderstorms can dump several inches of rain in a short time. All this rainfall means homes need extra protection against leaks and water intrusion.
Inspectors check for:
- Leaks in roofs and exterior walls. Damaged or missing shingles and improper flashings are common culprits.
- Gutters and downspouts that are clogged or draining too close to the foundation.
- Sloping soil or drainage issues that allow water to pool near the foundation.
- Leaky windows, doors, and siding that allow water intrusion.
- Signs of water damage, rot, or mold inside attics, crawlspaces and basements.
Homeowners should monitor during heavy rains for any leaks inside and make repairs to the roof and exterior promptly. Proper grading and downspout extensions help divert water away from the home’s foundation.
Hurricanes Bring Wind Damage and Heavy Rain
Houston’s location near the Gulf of Mexico means it endures its share of hurricanes and tropical storms. The high winds and torrential rain that come with these storms put homes at risk.
Inspectors check for:
- Roof and siding damage from past storms that should be repaired before the next hurricane season.
- Impact resistant windows and doors that can withstand debris in windstorms.
- Properly installed hurricane clips, braces, and anchors to reinforce the roof structure.
- Adequate tiedowns for mobile homes and exterior elements like storage sheds.
Homeowners need a hurricane preparation plan to protect windows, clear yards of loose debris, turn off utilities, and evacuate if necessary. Post-storm, inspect for roof leaks, moisture issues, or structural damage before permanent repairs are made.
Flooding Brings Extensive Water Damage
Houston’s flat topography and clay-rich soil makes it prone to flooding from heavy rainfall events. Many neighborhoods also sit in the 500-year floodplain. This means homes are at high risk for major flooding over their lifetime.
Inspectors check that:
- Homes meet minimum elevation standards in flood zones.
- Foundations are properly sealed to prevent water intrusion.
- Plumbing and utilities have backflow valves to prevent contamination during floods.
- There are no signs of past flood damage like water stains or mildew inside basements or crawlspaces.
Homeowners should research their property’s flood risk and obtain flood insurance if needed. Flood prevention measures like French drains, sump pumps, and berms can also help divert water away from the home. After floods, inspectors can check for contamination and ensure repairs bring the home up to code.
Annual Inspections Catch Issues Early
Houston’s climate puts extra wear and tear on homes with the heat, moisture, storms, and potential for flooding. Homeowners should conduct annual inspections to catch maintenance issues early before they become costly repairs. Inspectors can provide an objective set of eyes to find issues you may miss.
Some key areas for homeowners to inspect annually:
- The roof, checking for damaged or curled shingles and examining flashings around chimneys, vents, and valleys for water intrusion.
- The exterior, checking siding and trim for signs of water damage or cracks. Ensure caulking and weatherstripping are intact around windows and doors.
- The attic, checking for mold, mildew and excess moisture which can indicate roof leaks or poor ventilation.
- The foundation, checking for cracks or evidence foundation has settled. Ensure proper drainage and downspouts direct water away.
- Plumbing fixtures, checking for leaks and signs of water damage.
- HVAC systems, cleaning and servicing to ensure proper drainage and prevent mold growth.
Catching minor issues early is much cheaper than major repairs later. Houston’s climate means homes need a little extra maintenance and inspection to stay in top shape for years to come. Follow these tips specific to Houston’s weather to help inform your home inspections and prevent costly repairs.
