13 Surprisingly Simple Home Repairs You Can DIY to Save Big

There are many good things about owning a home, but paying for repairs isn't one of them. By some estimates, homeowners spend 1% to 4% of a home's value on maintenance and repairs every year. That's as much as $500 a month for a house worth $150,000. While there are certainly projects too big or dangerous for the typical homeowner to take on without a professional, you can save money by learning how to handle a few common repairs and maintenance projects yourself.

If the dryer isn't working as well as it used to, there may be lint in the vent that's restricting airflow. The folks at Repair Clinic, an online replacement part store, say you can clean out the dryer's ventilation system with a dryer vent cleaning brush that costs less than $20. If the dryer isn't spinning or heating at all, you may need a new thermal fuse. A fuse costs as little as $7 at Home Depot and takes a half-hour to replace.

Small and usually hidden away, sump pumps prevent flooding in basements and crawl spaces. John O'Brien, a lawyer from Chicago with experience doing his own home repairs, told Cheapism he was surprised how easy it is to replace the pump. New pumps start at less than $100, and all he needed was a screwdriver and a pipe to disconnect the old pump and install a new one.

When caulk begins to deteriorate or discolor, it needs to be replaced. Removing old caulk is usually the most laborious part of the job, but special caulk removal tools (starting at about $5) make it easier. Pre-shaped caulk strips that are pressed into place (also starting at about $5) make installing caulk a snap.

Judy Crockett shares a few DIY painting tips gleaned while working for her husband's interior painting company in Manistee, Michigan: Although it can be time consuming, prep work is the key to a professional finish. Be sure to scrape imperfections on the walls with a putty knife; wash to remove dust; and vacuum ducts, electrical boxes, and floors before starting to paint. Take your time and watch for drips as you go.

Crocket told Cheapism about a job where an electrician had moved a few outlets in a home and left holes in the wall. The homeowner wasn't able to find a drywaller willing to do such a small job, and the Crockets couldn't paint until the holes were patched. After a bit of studying and asking for help at the local hardware store, they were able to patch the holes themselves. It was easy enough that Crocket recommends that homeowners learn this skill as well.

If you have a table saw (or have a Home Depot or Lowe's nearby where you can rent one), you can install your own crown molding for less than $300. The molding itself is only around $3 to $8 per square foot, and Home Depot has a tutorial explaining just how to do it. 

A faucet with a drip is annoying, wasteful, and costly. Often a failing washer is to blame. Check the manufacturer's website to find out what type of replacement washer you need and turn to YouTube for instructional videos. The repair involves taking apart the faucet using a screwdriver and pliers. Washers can be found at hardware stores for less than $2 each, and sets of assorted washers cost about $7.

Like a leaky faucet, a leaky pipe under the sink often can be addressed without calling a professional. Generally, you just need a new washer or nut, but in some cases the entire p-trap (the curved section) has to be replaced. The parts should be $5 to $15 at a local hardware store, depending if they're plastic or metal. Be sure to turn off the water flowing to the sink before taking anything apart.

A clogged drain is never fun, especially when there's a disposal involved. With a bit of preparation, though, a homeowner can make a DIY repair. Kathryn Lagden of Burlington, Ontario, said that after watching an instructional video on YouTube, all she needed to clear a clogged disposal was an Allen wrench, a flashlight, tongs, and 15 minutes. There was a time she had limited experience with DIY home repairs, but watching instructional videos has helped her fixed her vacuum, laptop, and dishwasher without hiring a professional.

Attic insulation offers a hefty return on investment while cutting the overall cost of home energy use. You can do spray-foam or blown-in insulation, or get “batt” insulation that comes with plastic or foil backing in a roll sized to fit between standard-size floorboards — just unroll it where you want it. It holds up well over the years and is a cinch to do, so long as you measure the space between floorboards and order the corresponding size carefully for easier installation.

There are few things more obnoxious than the whine of metal on metal every time you open or close a door. Fortunately, it's easy to get rid. Put cardboard below to avoid scratching your floor, and just take the door off — removing hinge pins from the top with a flathead screwdriver or putty knife, or by inserting a nail or small screwdriver from below. (You may have to tap upward with a hammer.) Wipe the pins with oil, alcohol, or WD40 and slip the pins back into the aligned hinges. Wise DIYers will make removing and replacing the door a two-person job.
