7 Mistakes You're Making with Fall Home Maintenance (and How to Fix Them)

Fall is a useful time to prepare your home for cooler weather and seasonal rain. In San Antonio and the Hill Country, that means paying attention to more than leaves: summer heat, storms, expansive soils, and mineral-rich water can all affect how your home performs.

Use this checklist to catch routine maintenance needs early. If you find signs of damage or are unsure what you’re seeing, get a qualified professional to assess the issue before it becomes a larger repair.

1. You’re ignoring foundation drainage after a dry summer

Long dry spells can cause some clay soils to shrink. When rain returns, the soil can absorb water and expand. Repeated, uneven changes in moisture around a home may contribute to foundation movement. The risk varies by property, soil, and drainage conditions, so look for changes rather than assuming every crack signals structural damage.

How to fix it: Walk around your home after rain. Look for standing water, soil erosion, low spots, or downspouts that release water beside the foundation. Clear blockages and direct runoff away from the home without creating a new drainage problem on a neighbor’s property. Repair irrigation or plumbing leaks promptly, and avoid soaking one section of soil while the rest stays dry.

Consistent drainage helps reduce unnecessary wet-and-dry cycles around the foundation. If you notice new or widening cracks, sticking doors, or sloping floors, document the changes and seek a professional evaluation.

2. You’re skipping the HVAC check before the first cold front

A heating system that has been idle through a long, hot summer may not be ready to run reliably. A dirty filter can restrict airflow, and leaves or debris around outdoor equipment can interfere with operation. Finding a problem before a cold snap gives you more time to arrange service.

How to fix it: Replace or clean the filter according to the equipment manufacturer’s instructions. Clear leaves and vegetation around outdoor units, and test the heat before you need it. Pay attention to unusual odors, noises, or weak airflow. If the system needs repair, or you suspect an electrical, gas, or combustion issue, contact a qualified HVAC professional rather than opening or adjusting components yourself.

Routine service can help your system operate as intended and reduce the chance of an unexpected interruption. The U.S. Department of Energy also recommends regular filter maintenance as part of heating and cooling system care.

3. You’re neglecting the roof and flashing after summer storms

Texas roofs face heat, wind, and hail. Damage may be subtle: a lifted shingle, a damaged pipe boot, or a gap in flashing around a chimney or roof penetration can allow water in. A small defect may not be obvious from inside the home until staining or moisture appears.

How to fix it: From the ground, look for missing or displaced shingles, visible damage, and debris after a significant storm. Check ceilings and upper walls for new stains, but remember that the point where water enters the roof may be far from where it appears indoors. Have a qualified roofer inspect areas you cannot safely see.

Never climb onto a wet, damaged, or steep roof. Prompt assessment can help you identify a leak before it damages insulation, ceilings, or other interior materials. The National Weather Service advises checking for hail damage and taking steps to prevent water intrusion when damage is found.

4. You’re forgetting to clean the gutters before winter rains

Gutters packed with leaves and roof debris cannot move water efficiently. Overflow can wet exterior walls, erode soil, or leave water pooling near the foundation. Particularly troublesome when the ground is already saturated.

How to fix it: Clear gutters and downspouts before the rainy season, then check for loose fasteners, leaks, and sections that sag. Confirm that water flows through the downspout and discharges away from the house. Avoid leaning a ladder on a gutter, and hire a professional if the roofline is difficult or unsafe to reach.

Properly working gutters help control roof runoff before it reaches the soil beside your home. For more guidance, see the Building America Solution Center’s overview of gutters and downspouts.

5. You’re sealing gaps but overlooking weatherstripping

Caulking visible gaps can help limit drafts, but it is not a substitute for functioning weatherstripping around doors and windows. If a door does not close tightly or the weatherstripping is compressed or torn, conditioned air can escape and outdoor air can enter. That can make rooms less comfortable and increase heating and cooling demand.

How to fix it: Check door and window seals for gaps, damage, or areas where the material no longer makes contact. Replace worn weatherstripping with a product suited to the opening, and use caulk for appropriate stationary joints. Close doors and windows fully before testing for drafts.

Seal carefully: do not block required vents, drainage paths, or combustion-air openings. A well-sealed home can improve comfort, but ventilation and safe equipment operation still matter.

6. You’re skipping water-heater maintenance

Minerals in hard water can settle as sediment in some water heaters. Over time, buildup may affect operation or contribute to noise. How quickly it accumulates depends on your water and equipment, so follow the manufacturer’s maintenance instructions rather than assuming every tank needs the same service.

How to fix it: Check your owner’s manual for the recommended maintenance schedule and flushing procedure. If the manual calls for flushing, or you are unsure how to do it, ask a qualified plumber. Be cautious with older equipment or a tank showing corrosion, leaks, or damaged connections; flushing or valve operation may reveal an existing problem. Never discharge hot water where it can injure someone.

Regular, appropriate maintenance can help you spot leaks and keep the equipment operating as intended. If you rely on a private well, consider testing your water and asking a qualified provider about mineral content before choosing treatment equipment.

7. You’re ignoring attic ventilation and insulation

Attic insulation can become displaced, damp, or compressed, while soffit vents may be blocked by insulation or debris. These conditions can affect how well the attic manages heat and moisture. Temperature swings can make existing weak spots more noticeable, and disconnected or poorly insulated ducts can also waste conditioned air.

How to fix it: From a safe, stable attic walkway, look for wet or compressed insulation, roof-deck stains, disconnected ducts, and blocked soffit vents. Do not step on ceiling drywall; it may not support your weight. Keep required clearance around heat-producing equipment and preserve ventilation paths.

Air sealing and insulation improvements work best when planned together with the attic’s ventilation and moisture conditions. Avoid simply adding insulation over problems or blocking vents to keep the attic warm. The Department of Energy’s attic air-sealing guide explains why careful air sealing is an important part of attic performance.

Make a fall plan, and act on warning signs

You do not need to complete every task in one day. Start with roof drainage and visible storm damage, then check HVAC operation, seals, the water heater, and accessible attic areas. Keep notes and photos so you can compare conditions over time.

If you find signs of water intrusion, possible foundation movement, damaged roofing, or a concern you cannot safely evaluate, arrange a professional assessment. A qualified inspection can help clarify what needs attention and what may simply require monitoring.
