Common Drywall Issues and How to Repair Them

Have you ever noticed mysterious cracks creeping along your walls or small holes appearing out of nowhere? You’re not alone. Over 95% of homes across Canada rely on drywall, and with that comes a host of common problems homeowners face year after year. From accidental dents to moisture damage, these flaws are more than cosmetic. They can point to underlying issues that worsen if left unaddressed.

This blog will help Canadian homeowners understand what causes these drywall problems and, more importantly, how to fix them quickly and correctly. Whether you're a DIY enthusiast or planning to hire a local contractor, you’ll find solutions here to keep your walls clean, safe, and durable.

1. Cracks in the Drywall: What They Mean and How to Fix Them

Cracks are one of the most common drywall issues, often raising concerns about a home’s stability. Though they can look intimidating, not all cracks are severe. They typically appear due to the home's natural settling or improper installation. The following types of cracks are the ones to watch for and repair:

• Hairline Cracks : These are thin and often appear near windows or doors due to framing movement. Use joint compound and a putty knife to smooth over them, then sand and repaint.
• Corner Cracks : These are usually caused by stress at drywall joints. Reinforce with fiberglass mesh tape before applying compound.
• Ceiling Cracks : These may result from structural movement or sagging. Use a utility knife to open the crack slightly, apply tape, and follow up with two layers of joint compound.

Crack repairs improve both appearance and structural integrity. As troubling as a crack might seem, the bigger threat often lies behind bubbling or soft drywall.

2. Water Damage: Causes and Solutions

Water-damaged drywall is more than an eyesore. If left untreated, it can lead to mold, mildew, and structural rot. Leaks from plumbing or harsh Canadian winters are the primary culprits. Once the source of the moisture is fixed, these repair options can help restore your walls:

• Stained Patches : Cut out the stained section, replace it with new drywall, tape the seams, and reapply the texture if needed.
• Swollen or Soft Drywall : Remove and replace the damaged section entirely. Don’t try to patch over spongy drywall. It won’t hold paint or tape.
• Mold Growth : Use a mold-killing solution and replace the affected area. Always wear protective gear during removal.

Water issues often start small but grow fast, so early intervention is key. Physical damage usually follows, where water lingers, and that’s where dents and holes come in.

3. Dents and Holes: Quick Fixes for Common Damage

Whether from moving furniture, doorknobs, or energetic kids, drywall dents and holes happen in every home. Fixing these blemishes is usually straightforward. The following types of damage are easiest to tackle on your own:

• Minor Dents and Nail Pops : Apply joint compound with a putty knife, let dry, then sand and paint.
• Medium Holes (1–6 inches) : Use a drywall patch kit or a scrap piece of drywall. Tape around the edges and finish with compound.
• Large Holes : Cut out the area, screw in a drywall support, add a replacement piece, and blend with compound and paint.

These repairs don’t just restore your wall. They help prevent future cracking and structural issues. But not all drywall problems come from accidents. Some are baked in from the start.

4. Poor Installation: Signs and Corrections

Sometimes, the real issue isn't wear and tear. The drywall was installed poorly initially. Signs of poor installation may include visible seams, screw pops, or uneven textures. Here’s how to handle these lasting flaws:

• Visible Seams or Tape Lines : Sand the seam, reapply compound, feather the edges, then prime and repaint.
• Screw Pops : Remove loose screws, secure drywall with new ones nearby, then cover with compound and sand.
• Wavy or Uneven Surfaces : This often requires sanding high spots and skim-coating low areas with compound.

Correcting these issues early will save you from frequent repairs down the road. By spotting these common issues and knowing how to fix them, your drywall can last for years and stay looking fresh.

Minor issues like small cracks or holes are DIY-friendly. Hiring a contractor like Royal Crown Renos for large-scale damage or moisture problems ensures safety and long-term durability.

Yes, especially in basements or poorly ventilated areas. To prevent recurrence, it's essential to remove all affected drywall and treat the underlying cause.
