Owning a home comes with a never-ending list of maintenance tasks, and hiring a professional for every little fix can get expensive fast. The good news? Many common household repairs are surprisingly easy to do yourself, even if you’re not particularly handy. By tackling these simple DIY repairs to save money, you’ll not only save but also gain confidence in maintaining and improving your home. Let’s get to work!

Fix Leaky Faucets to Cut Your Water Bill

That constant drip from your faucet isn’t just annoying—it’s money slipping down the drain. A leaky faucet can waste hundreds of gallons of water a year, driving up your utility bill. The fix? Replacing a worn-out washer or O-ring, which costs only a few bucks.

Start by determining if you have a compression or cartridge faucet—compression faucets have separate hot and cold handles, while cartridge types move up and down for water flow.

Turn off the water supply under the sink, grab a wrench, and replace the faulty washer or cartridge. Reassemble everything, turn the water back on, and enjoy the silence. A plumber could charge $50 to $150 for this job, but you can do it yourself in under 30 minutes.

Repair Small Drywall Holes Like a Pro

Whether it’s from moving furniture, an accidental (or purposeful😬) elbow, or an overzealous doorknob, drywall damage is super common. Thankfully, patching small holes is incredibly easy and requires only a few inexpensive materials.

For tiny nail holes, use spackle and a putty knife. Apply a small amount, smooth it over, let it dry, and sand it down before painting.

For medium holes, a drywall patch kit for fist sized holes is your best friend—these come with mesh patches that provide a sturdy base for spackle. Once dry, sand it smooth and repaint.

For large holes, you’ll need to cut back a square/rectangular hole in the wall, install backing, and cut a new piece of drywall to match the size of the hole you cut in the wall. Backing is just material for the new piece to secure to. Then just tape, spackle, sand and paint!

Instead of paying a contractor $200 or more, you can fix multiple spots for under $20.

Replace Broken Light Switches and Outlets Safely

A malfunctioning light switch or outlet can be a fire hazard, but replacing it is easier than you might think. If you hear a crackling sound when flipping a switch, or an outlet stops working, it’s time for a swap.

Safety first: Turn off the power at the circuit breaker and test to ensure no current is flowing.

Remove the old switch or outlet, take a quick photo of the wiring for reference, and attach the new one following the same setup. Secure everything, replace the cover, and turn the power back on. This simple task can save you at least $75 in electrician fees and takes about 20 minutes per switch for the complete beginner.

Re-Caulk Your Bathroom to Prevent Mold and Water Damage

Old, cracked caulk around sinks, tubs, and showers isn’t just an eyesore—it can allow water to seep into walls and floors, leading to mold growth and expensive repairs. Re-caulking is a quick and affordable way to protect your home.

Use a utility knife to remove the old caulk, clean the area thoroughly, and let it dry. Load a caulk gun with waterproof silicone caulk and apply a smooth bead along the seam. Use a damp finger to smooth it out for a polished finish. This simple job costs around $20 but can prevent thousands of dollars in water damage.

Clean or Replace HVAC Filters to Lower Energy Costs

Your HVAC system works hard to keep your home comfortable, but a dirty filter forces it to work even harder, leading to higher energy bills and potential breakdowns. Swapping out or cleaning your filter regularly can make a huge difference.

Locate your air filter, typically found in the return air duct register or HVAC unit itself. If it’s covered in dust and grime, replace it with a new one (usually under $15) or wash it if reusable. This quick fix improves air quality, keeps your system running efficiently, and helps lower your power bill.

Tighten or Replace Loose Cabinet Handles and Drawer Pulls

Loose cabinet knobs and drawer pulls make your kitchen and bathroom look worn down. Instead of living with wobbly handles or broken pulls, take a few minutes to tighten or replace them.

Use a screwdriver to secure any loose screws. If the hole is stripped and the screw won’t stay tight, insert a toothpick with wood glue into the hole, then reinsert the screw for a snug fit. If your hardware is outdated, upgrading to modern handles is an easy, budget-friendly refresh. A full set of new knobs costs around $20 and can give your cabinets a brand-new look.

Final Thoughts

Taking care of these simple DIY repairs to save money will not only save you hundreds (if not thousands) of dollars but also help you become more confident in maintaining your home. With just a few tools and a little effort, you can keep your house in top shape without breaking the bank.
