For many homeowners, springtime and the nice weather that typically accompanies the season is the perfect time to start some DIY projects around the home. While a small paint job or garden cleanup seems pretty easy for even the novice of DIYers, there are some tasks that should be left to the pros.

The Canadian Home Builders Association has a few projects you should probably avoid taking on your own if you don’t have the technical experience.

Plumbing, electrical and gas repairs and installations can all require licensed contractors by law, depending on provincial regulations. Make sure you know the rules where you live – and follow them. For the sake of your family’s safety, work involving electricity and/or gas service should only be done by a qualified contractor. Because this type of work can result in a safety hazard if done incorrectly, permits are usually needed.

Roofing or other exterior work involving heights requires proper safety equipment that must be correctly used. If you don’t have such equipment – and know how to use it – don’t take chances, hire a pro.

Asbestos removal is another area where you should always use a professional, and provincial laws likely require this. Don’t risk your health, and that of your family, by doing this work on your own.

It always feels good to get out and complete a few projects around the house, just make sure if it’s a bigger task than you can handle, you get the right person for the job.
