Nobody Talks About These Home Repair Basics Until Something Breaks

This guide walks through five core home repairs that DIY‑minded homeowners can realistically tackle with basic tools. These are the “quiet” fixes that keep your place running smoothly and save you from emergency calls and weekend chaos.

1. Stop A Dripping Faucet (Without Destroying Your Sink)

A dripping faucet wastes water, drives up bills, and is way more fixable than it looks. Most modern kitchen and bathroom faucets use cartridges or rubber seals that wear out over time.

Step 1: Turn off the water and plug the drain

Find the shutoff valves under the sink (usually two: hot and cold) and turn them clockwise until they stop. If there are no shutoffs, turn off the main water supply for the house. Plug the sink drain with a stopper or rag so you don’t lose tiny screws.

Step 2: Identify your faucet type

Look for the brand name and take a quick photo with your phone. Most faucets are one of these:

• Single‑handle cartridge faucet
• Double‑handle compression faucet (older style with separate hot/cold)
• Ceramic disc faucet

Knowing the type lets you buy the right replacement cartridge or washer instead of guessing.

Step 3: Remove the handle and access the cartridge or stem

Pop off decorative caps on the handle with a small flathead screwdriver if needed. Use an Allen wrench or screwdriver to remove the handle screw. Gently lift the handle off. Underneath, you’ll see a retaining nut or clip holding the cartridge or stem in place. Remove it with an adjustable wrench or pliers.

Step 4: Inspect and replace worn parts

Pull out the cartridge or stem. Look for:

• Cracked rubber O‑rings
• Worn or flattened washers
• Mineral buildup

Take the old part to a hardware store for a precise match. Replace with the new cartridge/washers, lubricating rubber parts lightly with plumber’s grease (not petroleum jelly).

Step 5: Reassemble and test

Reinstall the cartridge or stem, secure the retaining nut or clip, then put the handle back on. Turn the shutoff valves or main water back on slowly. Open the faucet and check for drips at both the spout and around the base. If you still have a slow drip, tighten the retaining nut a tiny bit more—don’t overtighten, or you’ll damage the new parts.

2. Fix A Door That Won’t Close Or Keeps Swinging Open

Seasonal humidity, foundation settling, and loose hinges can all make doors scrape, stick, or swing on their own. Most of the time, you don’t need a new door—you just need a smart adjustment.

Step 1: Figure out what’s actually wrong

Close the door slowly and watch:

• Does it rub at the top or side?
• Is the gap uneven (tight at top, wide at bottom, or vice versa)?
• Does the latch line up with the strike plate?

This tells you if it’s a hinge problem, frame shift, or latch alignment issue.

Step 2: Tighten and reset the hinges

Using a screwdriver (preferably hand, not power), tighten all hinge screws on both the door and the frame. If screws just spin and don’t tighten, the holes are probably stripped.

For stripped holes:

Remove the screw, pack the hole with wooden toothpicks or a short piece of wooden skewer dipped in wood glue, snap it flush, and reinsert the screw. This gives the screw fresh wood to bite into.

Step 3: Pull the door back into alignment

If the top of the door is rubbing on the latch side, you may need to pull that corner back. An easy fix: move the top hinge on the frame side slightly toward the room.

• Loosen the top hinge screws on the frame (don’t remove fully)
• Insert a thin piece of cardboard or a business card behind the hinge
• Retighten the screws

This tiny shim can shift the door enough to stop rubbing.

Step 4: Adjust the strike plate so the latch catches

If the door closes but the latch doesn’t catch, color the latch with a dry‑erase marker or lipstick, close the door, and see where the mark hits the strike plate. That shows how far off it is.

If the misalignment is small, you can:

• File the strike plate opening slightly in the direction you need
• Or loosen the screws, shift the strike plate, and retighten

For bigger shifts, you may need to fill old screw holes with wood and re‑drill.

Step 5: Tame a door that swings open or closed by itself

If your door won’t stay where you leave it, the frame is slightly out of plumb. Quick fix: remove one hinge pin, gently bend it in the middle using two pliers, then tap it back in. The slight bend adds friction and keeps the door from drifting.

3. Replace A Dead Light Switch Safely

Light switches are used dozens of times a day, so they wear out. If a switch crackles, feels hot, or just stops working, replacing it is usually straightforward—but only if you handle the electricity properly.

Step 1: Turn off power at the breaker and verify

Locate your electrical panel and switch off the breaker labeled for that room. If the labeling is a mess, turn off one breaker at a time until the lights go out in the right area. Then use a non‑contact voltage tester at the switch box to confirm the power is truly off. Don’t rely only on the light being off.

Step 2: Remove the switch cover and inspect the setup

Unscrew the plastic cover plate and set it aside. Remove the mounting screws holding the switch to the box. Gently pull the switch out, keeping the wires visible and undisturbed.

Look at how many wires are connected and where:

• A standard single‑pole switch usually has two hot wires and a ground
• A three‑way switch (two switches control one light) has three wires plus ground

Take a clear photo before disconnecting anything.

Step 3: Label and disconnect wires

Use masking tape or a marker to label each wire based on where it’s connected (e.g., “top screw,” “bottom screw,” or “common”). Loosen terminal screws and remove the wires. If wires are pushed into backstab holes, release them with a small screwdriver in the release slot or cut and strip fresh ends.

Step 4: Attach wires to the new switch correctly

Match the new switch type to the old one (single‑pole vs three‑way). Connect wires to the new switch terminals:

• Black (hot) wires go on brass or black screws
• Ground (bare or green) wire goes on the green screw
• For three‑way switches, match the “common” wire to the black‑colored screw

Tighten screws firmly and ensure no bare copper is exposed beyond the terminals.

Step 5: Reinstall, test, then tidy up

Fold the wires back into the box carefully, avoiding sharp bends. Screw the new switch into place and reinstall the cover plate. Turn the breaker back on and test the switch. If everything works and there are no sparks, buzzing, or unusual heat, you’re done. If it trips a breaker or behaves oddly, turn it off immediately and consult an electrician.

4. Patch A Small Hole In Drywall So It Actually Disappears

From door knobs to wall anchors to “oops” moments while moving furniture, drywall takes a beating. Patching small to medium holes is very doable if you follow the right sequence instead of just globbing on spackle.

Step 1: Prep the damaged area

For nail or screw holes, remove any loose debris and slightly widen the hole with a utility knife so the compound has something to grip. For larger holes (like from a doorknob), trim the edges to a neat square or circle. Wipe off dust with a dry cloth.

Step 2: Choose the right patching method

Rough guide:

• Tiny nail holes: lightweight spackle
• Screw/anchor holes up to a dime size: spackle or joint compound
• Holes up to about 2–3 inches: adhesive mesh patch plus joint compound
• Larger holes: drywall repair panel or backing support + new drywall piece

For this guide, assume a small to medium hole up to a few inches.

Step 3: Apply patch and first layer of compound

If using a mesh patch, center it over the hole and press firmly. With a putty knife, spread joint compound over the patch, extending a couple of inches beyond the edges. Feather the edges so it’s thinner at the perimeter than the center. Let it dry completely (follow package times; often several hours).

Step 4: Sand lightly and build up thin layers

Once dry, sand the patched area with fine‑grit sandpaper (120–220 grit). Don’t press too hard—you’re smoothing, not digging. Wipe off dust. Apply a second thin coat of compound slightly wider than the first. Let dry and sand again. Repeat a third time if needed for a seamless finish.

Thin, wide layers hide patches better than one thick blob.

Step 5: Prime, paint, and blend

Unprimed compound absorbs paint differently than the wall, causing “flashing.” To avoid this, apply a small coat of primer over the patch and let it dry. Then paint the area with matching wall paint, feathering the edges into the existing paint. If you have to repaint an entire section, use a roller rather than a brush to match the wall texture.

5. Silence A Noisy Running Toilet And Lower Your Water Bill

A toilet that runs every few minutes or hisses constantly is wasting water and money. In most cases, the problem is a worn flapper, misadjusted float, or tired fill valve—not the whole toilet.

Step 1: Identify the kind of noise or behavior

Lift the tank lid and observe:

• Constant running or trickling into the bowl
• Toilet refills itself every few minutes
• Hissing sound at the fill valve

This points you to either a flapper/flush valve issue (water leaking into the bowl) or a fill valve/float issue (water level too high or valve not sealing).

Step 2: Turn off water and drain the tank

Shut off the valve on the wall behind or beside the toilet by turning clockwise. Flush the toilet and hold the handle down to empty as much water from the tank as possible. Use a sponge or towel to soak up any remaining water if needed.

Step 3: Replace the flapper if water is leaking into the bowl

Detach the flapper from the overflow tube and unhook the chain from the flush handle arm. Take the old flapper to the store to get a matching replacement (size and style matter). Clip the new flapper onto the overflow tube and reattach the chain, leaving a little slack so the flapper can fully close but not so much that it doesn’t lift when you flush.

If the toilet was refilling every few minutes, this alone often fixes it.

Step 4: Adjust or replace the fill valve to set the right water level

Turn the water supply back on slightly and watch where the water level stops. It should sit about 1 inch below the top of the overflow tube. If it’s too high:

• For float‑cup style valves, turn the adjustment screw or squeeze the clip and slide the float down
• For old float‑ball valves, bend the float arm downward slightly

If adjustment doesn’t work or the hiss never stops, replace the fill valve with a universal kit. Follow the included instructions: disconnect water supply line, remove old valve, install new one, and reconnect.

Step 5: Final checks and subtle tweaks

Turn water fully back on and let the tank fill. Listen for any ongoing trickle or hiss. Drop a few drops of food coloring into the tank and wait 10–15 minutes without flushing; if color shows up in the bowl, water is still leaking, usually from an improperly seated flapper or rough seat. Clean the flapper seat with a cloth or gentle scrub pad and reseat the flapper.
