On top of that, the insurance won't cover it because it wasn't done by a professional to begin with."There are a lot of things that you're not educated about, and especially if it's something that comes down to flooding your house, burning your house, potentially harming you and your family. Don't touch it. Simple as that," she added.Mike Jr. mentioned that some homeowners hired contractors who claimed to know their way around the electrical boxes. But with the number of wires running through these hidden boxes, the homeowners should hire a licensed electrician instead of a contractor. Small changes like these, he said, would cover them in the long run.He added that if a homeowner wanted to paint the house by themselves, they should try and paint the trims first. He believed that doing so would make them realise why people hired professionals to do it.Mike Sr. also had a tip for people who wanted to do their wiring and plumbing by themselves. He said that while they could act as their own electricians and plumbers, they could get a permit to ensure that their work was right. He explained that when they applied for such a permit, people would come to their house and tell them if they were doing something wrong.The Holmes Family Rescue stars also discussed impractical renovation trends. Mike Sr. stated that concrete countertops weren't his favorite trend because concrete absorbed things, making it unfit for a place like the kitchen. Sherry said she didn't like the ShipLaps do-it-yourself wallpaper trends.For more updates on Holmes Family Rescue stars Sherry, Mike Jr., and Mike Sr., fans of the show can follow their respective Instagrams: @sherryholmes, @mikeholmesjr, and @make_it_right.
