If you’ve ever thought about performing some DIY home improvements, you might want to read about these DIY disasters and think twice. It may sound like it’s going to be cheaper in the long run to do your own handiwork, but there are some situations that simply need a professional. 

These DIY horror stories are full of walls falling down, houses filling with gasoline, and electrical wires with a mind of their own. If there’s anyone who can convince you that you shouldn’t do the job yourself, it’s these Reddit contractors describing DIY experiments gone wrong.

  • A Guy Used A Little Too Much Expanding Foam

    From Redditor /u/Barbarian_Bob:

    Once met a guy who tried to replace his own windows, used expanding foam to “insulate” the space between the window box and the studs. It expanded far more than he anticipated and shattered thousands of dollars worth of brand new windows.

  • A Homeowner Knocked Down A Load-Bearing Wall

    From Redditor /u/Noaesh:

    Guy knocked down a wall to convert his kitchen/lounge/dining into an open plan concept. Wall was load bearing. [The home owner] Managed to f*ck himself out of $50,000AUD in order to save roughly $4,000 for engineering reports and a contractor.

  • They Made The Worst DIY Patio In The World

    From Redditor /u/Some_Drummer_Guy:

    One time, we came across a patio where the homeowner used play sand for the base and nothing more. It's any wonder that the damn thing was lop sided and falling apart. No 21AA gravel and slag sand base. No concrete edge or plastic edging. Just threw down a bunch of play sand, compacted it and laid a bunch of brick. It had been done improperly from the get-go and homeowner was clueless.

    There's a reason why we're called "professionals." We know what the f*ck we're doing. You do not. Call us instead of thinking you know it all and end up f*cking it all up.

  • They Built Their Own Load-Bearing Wall

    From Redditor /u/Rollerroman:

    We just recently remodeled a home that was built with 1X3 studs in the exterior load bearing walls. We could push the wall out a few inches if we leaned on it!
