Whether you consider yourself a master at home DIYs or prefer to leave repairs to the professionals, it’s always a good idea to know what projects are safe to tackle yourself and which will require an expert.

If it requires tampering with electricity: PRO
Even basic wiring can pose a potential threat if you aren’t an experienced electrician. If the task is as basic as installing a new light switch cover, go ahead and do it yourself. Otherwise, call in the professional.

If you need more space: DIY
Running out of room? Putting in a few more shelves or installing other kinds of wall storage is a great option for saving money and flexing your craftsman muscles—just be mindful of wiring in the walls!

If you need to dig: PRO
Basic mulching or adding stone to your garden is a simple project you should definitely do yourself to save money, but if your venture will involved digging around sensitive framework or pipes (like installing a pool), you’ll need someone with plenty of know-how to prevent potential catastrophe.

If you want to change the look of your fixtures: DIY
Updated doorknobs and cabinet handles may seem like no big deal, but they can make a huge difference to the look and feel of a room. The best part? New parts are relatively cheap, and installation time is minimal.

If you need to fill in the cracks: DIY
Weather and general wear and tear can do a number on our concrete or stone pathways. A bag of concrete at the hardware store is fairly inexpensive and easy to mix up for repairs you can make yourself without the distracting cement truck.

If you need to install large equipment/machines: PRO
You probably don’t need a professional to install a new microwave or toaster, but if you’re talking about a water heater or air conditioning system, you don’t want to end up spending more money in repairs—so hire the expert.
