First skill
Know your shutoffs
Before you learn to fix anything, learn to stop the damage. FEMA recommends that every household member know how to shut off the water, gas, and electricity. In the aftermath of a disaster, leaking gas is a major source of fires, burst pipes flood homes within minutes, and electrical faults can ignite gas leaks. The time to locate these shutoffs is now, not during an emergency in the dark.
Usually located in the basement, garage, crawl space, or where the water line enters the home. In warmer climates, it may be outdoors near the water meter. Turn the valve handle clockwise to close. Shutting off the water main does two things: it prevents contaminated water from entering your lines if there is a supply disruption, and it prevents clean water from draining out through a cracked pipe.
Test the valve now. If it is rusted, stiff, or does not fully close, have a plumber replace it before you need it. Individual shutoff valves also exist on the supply lines to toilets, sinks, dishwashers, and washing machines. Learn where each one is.
The main gas shutoff valve is typically located on the pipe running into the gas meter from the buried line. Use an adjustable wrench to turn the valve a quarter-turn so it sits perpendicular to the pipe. When the valve handle crosses the pipe, the gas is off.
Store a wrench near the meter in a sealed bag so it is ready when you need it. Some hardware stores sell non-sparking gas shutoff wrenches specifically designed for this purpose.
Once you turn off the gas, never turn it back on yourself. A trained technician from your gas company must inspect the system and relight all appliances. After a major disaster, this process may take days or weeks.
Locate your main electrical panel (breaker box), usually in the basement, utility room, or garage. To shut off power: switch off all individual circuit breakers first, then turn off the main breaker. No tools required. Turning off individual breakers first reduces the risk of an arc when you flip the main.
Keep the power off after a disaster until a professional confirms there are no gas leaks. Electrical sparks can ignite leaking gas. If the floor beneath your panel is flooded, do not touch the panel. Call your utility company.
Action step
Walk through your home today and locate all three main shutoffs. Label each one with a tag. Show every household member where they are and how to operate them. This takes 15 minutes and is the single most valuable home repair skill you will ever learn.

Electrical safety and simple fixes
Electricity demands respect. The U.S. Consumer Product Safety Commission estimates roughly 169,000 residential fires of electrical origin occur each year, causing over 1,100 deaths and $1.1 billion in property damage. Most of these fires involve overloaded circuits, damaged cords, or misused extension cords. The good news: the most effective electrical safety measures are inspections and habits, not complex repairs.
What you can and should do
Test GFCI outlets monthly
GFCI (Ground-Fault Circuit Interrupter) outlets are required in bathrooms, kitchens, garages, laundry rooms, and outdoor locations. Press the test button. If the power cuts off, the outlet is working. Press reset to restore. If the outlet does not trip when tested, it needs replacement. The CPSC recommends testing monthly and after any power outage.
Label your breaker panel
Every breaker should be labeled with the room or circuit it controls. Turn off one breaker at a time and walk through the house to identify which outlets, lights, and appliances lose power. Write clear labels. This takes 30 to 45 minutes and saves significant time during any electrical issue.
Inspect cords and outlets
Check power cords for fraying, cracking, or exposed wire, especially at stress points where the cord meets the plug and where it enters the device. Check outlets and switches for warmth, discoloration, or buzzing sounds. Any of these signs warrant immediate attention. Unplug the affected device or stop using the outlet and have it inspected.
Replace a light switch or outlet cover
Replacing a cracked cover plate requires no electrical knowledge. Turn off the breaker first as a precaution. Unscrew the old plate, screw on the new one. Exposed wiring without a faceplate is a shock hazard, especially in homes with children.
Hard boundary: what you never do yourself
Any work inside the electrical panel. Any work requiring new wiring through walls. Adding new circuits. Working on 240-volt connections (dryers, ranges, water heaters, HVAC). Aluminum wiring remediation. Building codes in most jurisdictions require a licensed electrician for panel work. The risk of shock, fire, and code violations makes this a non-negotiable professional boundary.
Weatherproofing
Seal the envelope
Your home's "envelope" is the barrier between inside and outside: walls, windows, doors, roof, and foundation. Gaps in the envelope waste energy year-round and become serious problems during extreme heat, cold, or storms. Most weatherproofing tasks require basic tools and materials from any hardware store.
Windows and doors
Weatherstripping around doors and windows deteriorates over several years. Check by closing a door on a piece of paper. If the paper slides out easily, the seal is gone. Replacement weatherstripping is self-adhesive and installs in minutes. For windows, inspect the caulk around the exterior frame. Cracked or missing caulk lets water and air in. Remove old caulk with a putty knife, clean the surface, and apply a new bead of exterior-grade silicone caulk.
Exterior walls and foundation
Walk the exterior of your home once a year. Look for cracks in the foundation, gaps where pipes or wires enter the house, and deteriorating mortar between bricks. Small foundation cracks (hairline to 1/4 inch) can be filled with hydraulic cement or masonry caulk. Gaps around pipes and wires should be sealed with exterior-grade caulk or expanding foam. Larger cracks, especially those that are widening, horizontal, or show signs of water intrusion, require professional evaluation.
Gutters and drainage
Clean gutters at least twice a year, in spring and fall. Clogged gutters cause water to overflow against the foundation, which leads to basement leaks and eventual structural damage. Check that downspouts direct water at least four feet away from the foundation. Downspout extensions are inexpensive and prevent thousands of dollars in water damage over the life of a home.
When damage happens
Emergency repairs that buy you time
Emergency home repairs are not permanent fixes. They are temporary measures that prevent further damage while you wait for professional help or better conditions. The goal is to keep the home habitable and prevent a manageable problem from becoming a catastrophic one.
Emergency roof tarping
After storm damage removes shingles or opens a hole, water intrusion begins immediately. A heavy-duty tarp (minimum 6-mil poly, ideally 10-mil or heavier) laid over the damaged area prevents further water damage to the interior. Extend the tarp at least four feet past the damage on all sides. Secure it with 2x4 lumber screwed through the tarp into the roof deck, or use sandbags along the edges if you cannot safely work on the roof.
Never work on a roof during active lightning, high winds, rain, or on a wet surface. Never work alone on a roof. If the pitch is steep or the damage is extensive, this is a professional job from the start.
Broken window
Clear the broken glass wearing heavy gloves and eye protection. Tape a piece of heavy-duty plastic sheeting (a trash bag will work short-term) over the opening from the inside, sealing all edges with duct tape. For better insulation and security, cut a piece of plywood to fit the opening and screw it into the window frame from the inside. Measure the opening before visiting the hardware store for replacement glass.
Burst or leaking pipe
Shut off the water main immediately. Open faucets at the lowest point in the house to drain remaining water from the lines. For a small crack or pinhole leak, a pipe repair clamp (available at hardware stores for $5 to $15) provides a temporary seal. Wrap the damaged area with the clamp and tighten.
For larger breaks, shut off the water and call a plumber. While waiting, contain the water: move belongings away from the leak, place buckets or towels to catch dripping water, and use a wet/dry vacuum if available. Document the damage with photos for insurance purposes before cleaning up.
Prevention
Maintenance that prevents emergencies
The best home repair is the one you never need because you caught the problem early. A simple seasonal maintenance routine costs nothing, takes a few hours per quarter, and prevents most of the emergency repairs described on this page.
Quarterly walk-through
Walk the exterior of your home once per season. Check the roof line for missing or damaged shingles. Inspect gutters and downspouts. Look at the foundation for new cracks. Check exterior caulking around windows and doors. Test exterior faucets and hose bibs. Look for signs of pest entry. This visual inspection takes 20 minutes and catches problems when they are small.
Annual systems check
Once a year, test all utility shutoff valves to confirm they still operate. Test all GFCI outlets. Check the water heater's temperature-pressure relief valve (lift the lever briefly; water should flow, then stop). Replace HVAC filters (more frequently if you have pets or allergies). Check supply line hoses to washing machines and dishwashers for bulging or cracking. Inspect the attic for signs of roof leaks, rodent entry, or insulation damage.
Documentation
Keep a home maintenance log. Record when systems were serviced, when parts were replaced, and what contractors were hired for what work. This log serves three purposes: it reminds you when maintenance is due, it provides a service history for warranty claims and insurance documentation, and it adds value to your home if you sell. A simple notebook or spreadsheet is sufficient.
