Step 2: The 15 fixes ranked by money saved#

PLUMBING (saves $150-400 per incident):

1. UNCLOG A DRAIN (saves $150-250)
   -> Pour boiling water down the drain first
   -> If that fails: 1/2 cup baking soda + 1/2 cup vinegar, wait 30 min, flush with hot water
   -> If that fails: use a plunger (cover overflow hole with wet rag first)
   -> If that fails: remove the P-trap under the sink (put a bucket under it first,
      unscrew the two slip nuts, clean it out, put it back)
   -> NEVER use chemical drain cleaners — they damage pipes

2. FIX A RUNNING TOILET (saves $150-300)
   -> Lift the tank lid and look inside
   -> If the flapper (rubber thing at bottom) is warped/old: replace it ($5 at hardware store,
      pulls right off, new one snaps on)
   -> If the float is too high: adjust the float arm down so water stops
      1 inch below the overflow tube
   -> These two fixes solve 90% of running toilets

3. FIX A LEAKY FAUCET (saves $150-250)
   -> Turn off water supply (valves under the sink, turn clockwise)
   -> Most leaks = worn washer or O-ring
   -> Search "[your faucet brand] [your faucet model] washer replacement"
   -> It's usually: remove handle, remove cartridge, replace rubber parts, reassemble
   -> Parts cost $5-10

WALLS AND SURFACES (saves $100-300):

4. PATCH A HOLE IN DRYWALL (saves $100-200)
   -> Small holes (nail/screw): fill with spackle, let dry, sand smooth, paint
   -> Medium holes (fist-sized): buy a drywall patch kit ($8), apply mesh patch,
      spread joint compound, let dry, sand, paint
   -> The secret: feather the edges so the patch blends into the wall

5. FIX A SQUEAKY DOOR (saves a service call)
   -> Remove hinge pin (tap up from bottom with screwdriver)
   -> Coat pin with petroleum jelly or WD-40
   -> Replace pin. Done.

6. FIX A STICKING DOOR (saves a service call)
   -> Find where it sticks (look for shiny/rubbed spots on the edge)
   -> Sand that spot with medium sandpaper
   -> If the whole door sags: tighten the top hinge screws (use longer screws
      if the holes are stripped — 3-inch screws into the door frame stud)

ELECTRICAL — SAFE STUFF ONLY (saves $200-400):

7. REPLACE A LIGHT SWITCH OR OUTLET (saves $200)
   -> Turn off the breaker for that circuit (test with a voltage tester or plug in a lamp)
   -> Remove cover plate, unscrew switch/outlet from box
   -> Take a photo of which wire goes where
   -> Disconnect wires, connect to new switch/outlet in same positions
   -> Screw back in, replace cover, turn breaker on
   NOTE: if you see aluminum wiring (silver color), STOP and call a professional

8. FIX A TRIPPED BREAKER (saves a service call)
   -> Find your electrical panel (usually basement, garage, or utility closet)
   -> Look for the breaker that's in the middle position (not fully on or off)
   -> Push it fully to OFF, then back to ON
   -> If it trips again immediately: you have an overloaded circuit or a short.
      Unplug everything on that circuit and try again. If it still trips, call an electrician.

EVERYTHING ELSE:

9. TIGHTEN A LOOSE HANDLE/KNOB (saves frustration)
   -> Look for a set screw on the base (tiny screw on the side or bottom)
   -> Tighten it. That's literally it.

10. FIX A STUCK WINDOW (saves $100-200)
    -> Score the paint seal with a utility knife along the edges
    -> Spray silicone lubricant in the tracks
    -> Tap the frame gently with a rubber mallet or your palm

11. STOP A DRAFTY WINDOW/DOOR (saves $50-200/year in heating)
    -> Buy adhesive weatherstripping ($5-10)
    -> Clean the surface, apply the strip along the gap
    -> For windows: shrink-wrap window insulation kits ($15 for 5 windows)

12. RECAULK A BATHTUB/SHOWER (saves $150-250)
    -> Remove old caulk with a utility knife
    -> Clean the gap with rubbing alcohol
    -> Apply new silicone caulk (cut tip at 45 degrees, steady line)
    -> Smooth with a wet finger. Let cure 24 hours.

13. FIX A GARBAGE DISPOSAL (saves $150-200)
    -> If it hums but doesn't spin: turn it off, look underneath for a hex key hole,
       insert the hex wrench (usually comes with the unit), turn back and forth to free the jam
    -> If it does nothing: press the reset button on the bottom of the unit
    -> NEVER put your hand inside a disposal

14. UNCLOG A SHOWERHEAD (saves a service call)
    -> Unscrew showerhead
    -> Soak in white vinegar overnight
    -> Scrub holes with old toothbrush
    -> Reattach with new teflon tape on threads

15. HANG SOMETHING HEAVY ON A WALL (prevents damage)
    -> Find the stud (knock on wall — hollow = no stud, solid = stud)
    -> Or use a stud finder ($15)
    -> Drill into the stud. It will hold 50+ lbs easily.
    -> No stud available: use toggle bolts ($5), NOT plastic anchors for heavy items.

If This Fails#

• Call 211 or search "free home repair assistance [your county]" — many communities have volunteer repair programs for low-income homeowners (Habitat for Humanity Repair Corps, Rebuilding Together)
• Ask your hardware store — staff at independent hardware stores will often walk you through a repair for free. Bring the broken part and a photo of the setup.
• Try a local handyman school or community college — many offer free or low-cost Saturday repair workshops where you can bring your own project
• Cross-reference: Start a Micro-Business skill — if you're paying for repairs you can't afford, learning repair skills can also become income (handyman services: $40-80/hr)
• For renters: document and request — if a DIY fix isn't working, your landlord is legally responsible for habitability repairs. Submit requests in writing and know your tenant rights (search "[your state] tenant rights repairs")

Rules#

• Always mention safety: turn off water before plumbing, turn off breaker before electrical
• If it involves gas lines, main electrical panels, or structural work: tell the user to call a professional
• Start with the simplest diagnosis before suggesting complex fixes
• Renting vs owning matters: renters should notify landlord for major issues but can fix minor things

Tips#

• YouTube is the best repair teacher. Search your exact problem + your exact model number. Someone has filmed the fix.
• Take photos before you take anything apart. You'll thank yourself when reassembling.
• Hardware store employees are usually the most helpful people on earth. Bring the broken part with you and ask.
• "Righty tighty, lefty loosey" — the universal rule for screws, bolts, and most fittings.
• If water is actively spraying: your first job is finding the shutoff valve, not fixing the pipe. Main shutoff is usually near the water meter.
