Home Improvement
Five simple home repairs worth learning, from patching wall holes to fixing a running toilet, plus a clear line on the gas and electrical work to leave to a pro.
There's a particular feeling when something small breaks in your home and you realize you have no idea how to fix it. The drip you can't stop. The toilet that hisses all night. The door that announces every trip to the kitchen with a squeal. It's not that these things are hard. It's that nobody ever showed you, so they feel like mysteries that require a paid expert.
Most of them don't. A short list of basic repairs will handle a surprising amount of what goes wrong in an ordinary house, and learning them is the difference between a frustrated afternoon and a five-minute fix. Just as important is knowing where the list ends, because some repairs are not yours to attempt no matter how many videos you've watched. Let's cover both.
Nail holes and small dings are the most common wall damage there is, and they're genuinely easy. For tiny holes, a dab of lightweight spackle or filler on a putty knife, pressed in and smoothed flush, is all you need. Let it dry, sand it lightly until it's level with the wall, and touch it up with matching paint.
Slightly larger holes, the kind a doorknob makes, need a patch behind them for support before you fill, but the principle is the same: back it, fill it, sand it, paint it. The mistake people make is overloading the spot with filler in one go. Thin layers dry better and sand smoother. Patience beats brute force here, as it does with most of this list.
Before you pour anything down the drain, reach for mechanics. A slow sink or tub is usually hair and gunk caught near the top. A simple drain snake or even a bent piece of stiff wire often pulls the culprit out in seconds. A plunger, used properly with enough water in the basin to seal it, clears plenty of clogs through pressure alone.
I steer people away from harsh chemical drain cleaners as a first move. They're rough on older pipes, dangerous if they splash, and they don't address a physical blockage so much as hope to dissolve around it. If mechanical methods and a bit of patience don't work, the clog may be deeper in the line, and that's the point to call a plumber rather than escalate to something corrosive.
Reach for the snake before the chemicals. Your pipes and your skin will thank you.
That endless hissing or periodic refilling is almost always one inexpensive part. Lift the tank lid and watch. In most toilets, the flapper, the rubber seal at the bottom of the tank, has worn out and no longer seals, so water trickles continuously from tank to bowl. Replacements are cheap and usually clip into place by hand after you shut off the supply valve and drain the tank.
If it's not the flapper, the fill valve or float may need adjusting so the tank stops filling past the overflow tube. None of this requires special skill, just a willingness to take the lid off and look. A running toilet quietly wastes a startling amount of water, so this is one of those fixes that pays for itself fast.
A squeaky hinge is friction, plain and simple, and it's one of the most satisfying fixes on this list because the result is instant. Often all it takes is a little lubricant worked into the hinge while you swing the door back and forth to spread it. For a stubborn one, you can lift the hinge pin partway, apply lubricant along it, and tap it back in.
While you're there, check the screws. A door that's also sticking or rubbing the frame sometimes just has a loose hinge screw, and snugging it up solves two problems at once. Small, but the daily relief is real.
Old caulk that's cracked, peeling, or gone moldy is both ugly and a real problem, because its job is keeping water out of seams. Renewing it is approachable. Pull or scrape away every bit of the old caulk, clean and dry the surface thoroughly, then lay a steady new bead and smooth it with a damp finger or tool.
The two things that ruin a caulk job are leftover old caulk underneath the new and applying it to a damp surface. Take your time clearing the gap and make sure everything is dry, and a fresh line of caulk will both look sharp and do its waterproofing job for years.
Here's the part I want you to take most seriously. Confidence with the repairs above does not transfer to systems that can hurt you or your home. There's a clear line, and crossing it is where DIY goes wrong.
Knowing where to stop isn't a failure of nerve. It's the most professional instinct you can have, and the tradespeople I respect most are the ones who'll tell you honestly when a job is above their certification too.
So learn the everyday five. Patch the wall, clear the drain, fix the toilet, hush the door, renew the caulk. They'll cover a real slice of ordinary home life and save you money and waiting around. Then hold that second list just as firmly. A capable homeowner isn't the one who attempts everything. It's the one who knows precisely which jobs are theirs and which deserve a phone call.
