Wall problem is an issue the average homeowner will have to cope with at some point. While a handful of homeowners may be able to address their drywall problems, it will prove challenging for the average homeowner to rectify. You are better off hiring an expert to do the job for you because repairing and replacing drywalls is time-consuming and you must always pay very close attention to details. Otherwise, you will cause structural damages, jagged and a clumsy appearance to your wall. That said, here are some of the many factors that can damage your drywall. 

• Water damage: we are sure you have seen those ugly looking brown stains; leaking pipes probably caused it. When left unaddressed, water damage will undermine the architectural integrity of your drywall and is known for creating health hazards. That said, once the cause has been diagnosed, repair or replaced, then you can move on to painting.
• Holes: you might be surprised to know, but holes in drywall is a big issue for homeowners. Accidents happen, and someone or something can quite easily, and forcefully slam into the wall, leaving a small or worrying puncture behind. 
• Loose drywall tape:  This doesn't happen very often, but the tape between drywall sections tends to become loose at times. When this happens, it cracks and peels in long strips. The cause for this usually stems from an excess of humidity or, or even faulty installation. Regardless of what caused it or not, it damages the paint and warrants your attention.
• Wear and tear: Whether it's swinging doors, furniture scuffs resulting from careless furniture handling, or involuntary accidents, drywall takes its fair share of wear and tear.
• Popping nails: When nails aren't securely affixed to joints, they will often pop through from the drywall.
