Home improvement is a huge industry.

Consumers spent $230 billion fixing their homes last year.

Many people are doing home improvement projects themselves.

While it is considered fun and cost-friendly to some people, experts advised that do-it-yourself disasters are on the rise.

When Margaret-Ann Anderson moved into her home, the house had an unfinished basement. The basement was framed and had electricity, so she said she believed it was good to go.

“We assumed it was fine, and just put up the wallboard and the drywall and finished it," said Anderson.

However, the basement had major electrical problems.

“We didn't realize it was not fine, and it could have burned down," added Anderson.

Steven McCoy, a specialist in fixing bad repair jobs, said there is a good reason do-it-yourselfers -- DIYs -- try to tackle the work.

“It's primarily the money. Home repair is expensive," said McCoy.

But when things go bad, homeowners could end up spending even more than if you’d hired a professional to begin with.

"If you have to redo the work that's done by a DIY person because they were going to save money, that project will probably cost 25 to 50 percent more," said Paul Winans of the National Association of the Remodeling.

There are some things homeowners could do to save some money.

Experts have said to think about surfaces, such as flooring, painting patching walls, ceiling and tiling.

Landscape projects are doable, too, experts said.

So, what should homeowners stay away from?

“Avoid areas where you need to make things waterproof. I wouldn't advise people attempting roofs. Beware of things that put you in the position of having to learn something new fast," said Winans.

Homeowners could also reduce the risk of things going awry by consulting with professionals.

“Even if you want to do the job yourself, take the time to research it and to visit with the folks who really know what they're doing," said McCoy.

Experts said trouble could occur if people don’t know what they are doing.

“We're just very thankful it did not burn down, and feel very blessed," said Anderson.

Many contractors will not touch a do-it-yourself project unless they can completely start fresh because, in some cases, contractors might be legally responsible for not only what work is being done, but also any work that was previously done.
