DIY or Hire a Pro? How to Decide

Doing a repair yourself can save money and be deeply satisfying. It can also cost far more if it goes wrong. A simple set of questions helps you decide.

Ask five questions

Is it safe? If the job involves live electricity, gas, structural elements, roofs or heights, or hazardous materials, the risk may outweigh the savings.
Do I have the skill? Be honest. Watching a video is not the same as having done it.
Do I have the tools? Renting or buying tools can erase the savings, and the wrong tool can cause damage.
What is the worst case? If a mistake means a mess, you can fix, DIY is reasonable. If it means a flood, a fire or a failed inspection, think again.
Does it need a permit? Many repairs and upgrades require one. If so, check whether you are allowed to do the work yourself in your area.

Good DIY candidates

These tasks are usually within reach for a careful beginner, with the right instructions:

Painting and caulking.
Patching small drywall holes. See our drywall patching guide.
Replacing a faucet aerator, a showerhead or a toilet flapper.
Changing air filters and smoke alarm batteries.
Installing shelves, curtain rods and simple hardware.
Basic lawn and garden care.
Cleaning gutters, from a stable ladder and with a spotter.

Think twice

These jobs can be done by experienced DIYers but carry real risk if done wrong:

Replacing a light fixture or switch (turn off the breaker and test the wires).
Fixing a running toilet or a slow drain beyond the basics.
Installing a ceiling fan.
Tile work and flooring.
Building a deck or a fence, which may need a permit.

Leave to the pros

For safety, legal and cost reasons, these are usually best handled by licensed professionals:

Electrical panel work and new circuits. Mistakes can start fires or cause shock.
Gas lines and gas appliances. Leaks and carbon monoxide are serious dangers.
Structural changes, such as removing or altering load-bearing walls.
Roof repairs, because of fall risk and the cost of water damage when done wrong.
Major plumbing, such as sewer lines, water mains and re-piping.
HVAC refrigerant work, which in many places requires certification.
Asbestos, lead paint or mold, which need proper testing and handling.

Count the true cost

DIY savings are not just the labor you avoid. Subtract tool costs, extra trips to the store, your time and the risk of redoing the job. On the other side, a pro brings speed, warranties and experience. Sometimes the best compromise is to do the prep and cleanup yourself and hire a pro for the skilled middle.

Check your insurance and warranties

Some warranties and insurance policies can be affected by unpermitted or non-professional work. If you are unsure, ask before you start.
