Small repairs you’ve been ignoring usually take less time than thinking about them. This guide walks through five practical DIY fixes that upgrade how your home looks and works, without needing a renovation budget or a pro. Each project is broken into clear steps, with tools, safety notes, and simple techniques you can actually follow.
Project 1: Stop a Dripping Faucet
A dripping faucet wastes water and slowly raises your bill. In many cases, the fix is as simple as replacing a worn washer or cartridge. You don’t need plumbing experience—just patience and the right parts.
Tools & materials
- Adjustable wrench
- Screwdriver (Phillips and flathead)
- Replacement washer or cartridge (match your faucet brand/model)
- Plumber’s grease
- Rag or towel
Step-by-step
**Turn off the water supply**
Look under the sink for the shutoff valves on the hot and cold lines. Turn both knobs clockwise until they stop. Open the faucet to release pressure and confirm water is off.
**Plug the drain and prep your workspace**
Put the sink stopper in or use a rag to block the drain so small screws don’t fall in. Lay out a towel to place parts in order as you remove them.
**Remove the handle and access the stem or cartridge**
Pry off any decorative cap to reveal the handle screw. Unscrew it and lift off the handle. Depending on the faucet type (compression, cartridge, or ball), you’ll see a nut, stem, or cartridge beneath. Take a photo before removing anything so you know how it goes back together.
**Replace the worn part**
For compression faucets, remove the stem and replace the rubber washer and O-ring at the end. For cartridge faucets, pull out the cartridge and replace it with an identical one. Lightly coat new rubber parts with plumber’s grease to help them seal and move smoothly.
**Reassemble and test**
Rebuild the faucet in reverse order, using your photo for reference. Turn the shutoff valves back on slowly while watching for leaks. Turn the faucet on and off a few times. If drips persist, tighten connections gently—don’t overtighten or you can damage threads or seals.
Quick tip: If you’re unsure which replacement part you need, take the old cartridge or stem to the hardware store and match it directly.

Project 2: Refresh a Room With New Caulk Around Tubs and Sinks
Old, cracked, or moldy caulk around tubs, showers, and sinks makes a clean bathroom look dirty. Re-caulking is a low-cost way to instantly freshen the space and improve water protection.
Tools & materials
- Utility knife or caulk removal tool
- Painter’s tape
- Caulk gun
- Tub and tile caulk (100% silicone or labeled “kitchen & bath”)
- Rags and rubbing alcohol or bathroom cleaner
- Disposable gloves
- Small bowl of water (for smoothing)
Step-by-step
**Remove old caulk completely**
Use a caulk removal tool or a sharp utility knife to cut along both edges of the old bead. Peel it away slowly. Scrape off residue until the surface is as clean and smooth as you can get it. This step matters more than perfect technique later.
**Clean and dry the area thoroughly**
Scrub the joint area with bathroom cleaner to remove soap scum, mildew, and dust. Rinse and let it dry fully—if you can, leave it overnight. Caulk won’t adhere well to damp surfaces.
**Mask clean lines with painter’s tape**
Apply painter’s tape in straight lines about 1/8" from the joint on both sides. This guides your bead and keeps caulk off tile or tub surfaces. Press tape down firmly to prevent caulk from bleeding underneath.
**Apply a steady bead of caulk**
Cut the caulk tube tip at a 45-degree angle, making a small opening. Load it into the caulk gun. Hold at a consistent angle and squeeze the trigger slowly, pulling the gun along the joint in one steady motion. You want a continuous bead—not too thick, not too thin.
**Smooth, remove tape, and let cure**
Wet a gloved finger with water and gently smooth the bead, pressing it into the gap. Peel off the painter’s tape while the caulk is still wet, pulling away from the joint. Let the caulk cure according to the package directions (often 24 hours) before using the tub or sink.
Quick tip: Use silicone caulk specifically labeled for bathrooms—it resists mold and stays flexible longer than general-purpose caulk.

Project 3: Fix a Loose Interior Door Handle
A wiggly or sagging door handle is annoying and can eventually fail. Tightening or re-seating it is usually a 10–15 minute job that makes your doors feel solid again.
Tools & materials
- Phillips and flathead screwdrivers
- Allen wrench (for some handle styles)
- Small container for screws
- Wood toothpicks and wood glue (for stripped screw holes, if needed)
Step-by-step
**Inspect both sides of the handle**
Open the door and look at the interior and exterior handle plates. Locate all visible screws. Some modern levers have hidden set screws underneath or on the neck of the handle.
**Tighten visible screws first**
Using the correct screwdriver, tighten each screw a little at a time, alternating sides. Check the handle for play after each adjustment. Often, this alone solves a loose handle.
**Remove the handle if it’s still loose**
If tightening doesn’t help, fully remove the screws and gently pull the two halves of the handle apart. Note how the spindle (the square rod) fits through the latch. Take a quick photo to reference when reassembling.
**Repair stripped screw holes (if necessary)**
If the screws no longer bite into the door, the holes may be stripped. Dip wood toothpicks in wood glue, insert several into the hole, and snap them off flush. Let the glue dry (follow the glue’s directions), then reinsert the screws. The new wood fibers give the screws something solid to grab.
**Reassemble and test operation**
Put the handle back together, aligning the spindle and latch correctly. Tighten screws evenly. Close and open the door several times, checking the latch engages smoothly and the handle doesn’t wobble. Adjust tension as needed—but avoid overtightening, which can bind the latch.
Quick tip: For handles with tiny set screws, use the exact size Allen wrench—undersized tools can strip the screw head quickly.

Project 4: Replace a Wobbly Light Switch or Outlet
Loose switches and outlets aren’t just irritating—they can be a safety issue if wires are stressed. Securing them properly makes them safer and helps wall plates sit flush and neat.
Safety first: If you’re not comfortable working around wiring, hire a licensed electrician. Never work on live circuits.
Tools & materials
- Non-contact voltage tester
- Flathead and Phillips screwdrivers
- Replacement wall plate (if cracked)
- Outlet or switch shims (or small pieces of sturdy cardboard)
Step-by-step
**Turn off power at the breaker**
Identify the correct circuit in your breaker panel and switch it off. Don’t rely solely on flipping the switch on the wall.
**Confirm power is off**
Remove the wall plate screws and gently pull the plate away. Use a non-contact voltage tester near the screw terminals or wires. Only continue if the tester shows no voltage.
**Inspect the mounting and box**
Check how the switch or outlet is secured to the electrical box. Usually, two screws run through the device “ears” into the box. Wobble often comes from these screws being loose or the box sitting too far back in the wall.
**Tighten and/or shim the device**
First, try tightening the mounting screws evenly. If the device still sits recessed, add shims behind the mounting ears or between the box and device to bring it flush with the wall surface. Tighten until secure but not bending the device.
**Reinstall the wall plate and restore power**
Align the wall plate and hand-tighten the screws—don’t crank them down or you can crack the plate. Turn the breaker back on and test the switch or outlet for solid feel and proper operation.
Quick tip: If the electrical box itself is loose inside the wall, or if you see damaged wiring, stop and call an electrician. That goes beyond a simple DIY fix.

Project 5: Quiet a Squeaky Floorboard
Squeaks usually come from wood rubbing against nails, screws, or other wood. You can often quiet them from above, without opening the floor from below.
Tools & materials
- Stud finder (optional but helpful)
- Drill with countersink bit
- Trim-head wood screws (1 1/4" to 2", depending on floor thickness)
- Wood filler or wax sticks (for hiding holes in wood floors)
- Hammer and finishing nails (for carpeted floors, optional)
Step-by-step
**Find the squeak source**
Walk slowly over the area and listen. Mark the precise spots that squeak with painter’s tape or a pencil. Squeaks often run along joists, so you may find a line of noisy spots.
**Locate the floor joist**
Use a stud finder set to “deep scan” or tap and listen for a solid sound to locate the joist under the squeaky area. Screwing into a joist gives the best, longest-lasting fix.
**For bare wood floors: secure with screws**
Drill a small pilot hole at an angle through the floorboard and into the joist. Drive a trim-head wood screw until it pulls the board down snug. Don’t overtighten; stop when the squeak stops. Countersink the screw slightly and fill the hole with color-matched wood filler or a wax stick.
**For carpeted floors: fix through the carpet**
Locate the joist under the carpet. Drive a thin screw through the carpet, pad, and subfloor into the joist. Tighten until the squeak stops. Gently pull the carpet fibers around the screw head to hide it. Specialized squeak repair kits are available that let you snap the screw head off below the carpet surface.
**Test and adjust**
Walk the area again. If you still hear squeaks, repeat the process a few inches away along the joist line. It may take 2–3 screws in a small area to fully quiet it.
Quick tip: In older homes, temperature and humidity can bring squeaks back seasonally. Securing the flooring to joists is more reliable than just pounding in more nails.
