I messed up my living room wall pretty bad trying to hang a shelf. The anchor pulled out and left a jagged hole about the size of a golf ball. I watched a few repair videos and bought a patch kit but the result looked worse than the damage. A coworker told me about a local service for drywall repair Toronto. The person who came over filled the hole, sanded it down, and textured it so you could not even tell anything happened. Took maybe thirty minutes and cost me around a hundred bucks. No mess left behind and no stress on my end. If you are tired of failing at DIY like I was, just call someone and save yourself the headache.
