How to Spot & Solve Hidden Drywall Issues After the Holidays

January 21, 2026

The hustle and bustle of the holidays are behind us, but as you start packing up the lights and storing festive décor, you may notice a few strange cracks, dents, or watermarks along your drywall. The post-holiday season is the perfect time to give your home a closer inspection, especially when the winter chill in Canada can exacerbate hidden drywall issues. At Drywallers.ca, we know homeowners in Toronto, the GTA, and across Ontario want to keep their homes looking fresh for the new year. Here’s how to spot those sneaky drywall problems and what you can do about them.


Why Do Drywall Issues Surface After the Holidays?


Holiday gatherings, fluctuating indoor temperatures, increased humidity, and extra wall decorations can put unexpected stress on your drywall. Maybe you hung a few heavy wreaths, or perhaps guests brushed against high-traffic hallways—either way, the signs may not show up until the end of January. Canadian winters make things more complicated, as constant heating dries out the air, sometimes causing the drywall to contract and crack.


Common Hidden Drywall Problems in January


Don’t wait until spring to address drywall concerns. After the holidays, look out for these issues:


  • Hairline cracks around windows, doors, or ceilings
  • Water stains or damp spots, especially near exterior walls
  • Popped nails or screws, which can leave small bumps or holes
  • Peeling paint or bubbling, which may signal moisture behind the wall
  • Subtle bulges or unevenness, pointing to hidden leaks or structural shifts

Quick Tip: Use natural winter daylight to inspect for shadows or irregularities that are easily missed in artificial light.


How Can You Tell If There’s Mold Behind Drywall?


A trending question we get from homeowners every winter is, “How can I tell if there’s mold behind my drywall?” Mold can thrive during the cold season if moisture gets trapped after holiday spills, leaks, or condensation from heating.


Here’s what to watch for:


  • Musty odors that don’t go away, even after cleaning
  • Discoloration that looks yellow, green, or black under the paint
  • Soft or damp spots when you press on the wall

If you suspect mold, it’s best to call a local professional for an inspection. At Drywallers.ca, we use thermal imaging and moisture meters to check for hidden problems behind your walls. Early detection is key to minimizing damage.


Fixing Drywall Issues: DIY or Call a Pro?


Some minor drywall imperfections are easy to fix with a bit of spackle and paint, especially if you’re tackling nail pops or small cracks. However, larger issues like water damage, bulging, or persistent stains signal a bigger problem and call for expert attention. Here’s when you should call Drywallers.ca:


  • Multiple cracks appearing suddenly, especially near windows or ceilings
  • Signs of ongoing moisture, like soft walls or a persistent musty smell
  • Recurring nail pops or large holes from holiday décor mounts
  • If DIY repairs don’t blend in or the damage keeps returning


Why Choose a Local Drywall Expert in Toronto and Surrounding Areas?


When it comes to your home’s drywall, hiring local means you benefit from professionals who understand the specific effects of an Ontario winter. Drywallers.ca is familiar with how freeze-thaw cycles, home heating, and holiday traffic can all impact your walls.

Seasonal Prevention Tips for Next Year

  • Use removable hooks or adhesive strips for hanging decorations
  • Monitor humidity indoors and use a dehumidifier if necessary
  • Address any leaks or drafts as soon as you notice them
  • Schedule a pre-winter drywall inspection to catch problems early
