Drywall is one of the most important parts of any home. It shapes the walls, protects the structure, and gives every room a clean and finished look. But older Canadian homes face more drywall problems than newer homes because time, moisture, settling, and poor past repairs all take a toll.
If you live in an older home, you have probably seen cracks, uneven surfaces, peeling tape, soft spots, or stains on walls and ceilings. These are not random problems. They are warning signs that your drywall needs attention.
This guide breaks down the most common drywall problems in older Canadian homes. You will understand what causes them, how they look, and when to call a drywall repair service before the damage spreads.

Why Older Canadian Homes Get More Drywall Problems
Canada has a harsh climate. Winters are cold and dry. Summers get humid. Temperatures swing fast. Snow melts into the foundation. Old insulation loses its strength. All of this puts pressure on drywall.
Older homes also deal with wear and tear from past renovations, outdated building materials, and repairs that were not done correctly. When you combine age with temperature changes and moisture, drywall becomes vulnerable.
Here are the main reasons older Canadian homes show more drywall damage:
- Settlement over many years
- Moisture from leaks, humidity, and temperature changes
- Poor taping or finishing by past owners
- Old drywall that has weakened over time
- Drafts and shifting in older structures
- Poor insulation that traps moisture behind the walls
Because of these issues, services such as drywall installation, drywall boarding, and drywall finishing become essential to restore the home to a safe and clean condition.
Now let us go deeper into the main drywall problems you will commonly see.
1. Cracks on Walls and Ceilings
Cracks are the number one drywall problem in older Canadian homes. You see them around doors, windows, ceilings, and sometimes right across the middle of a wall.
Why cracks appear
Older homes settle more over time. The soil under the house shifts. The structure moves slightly each season. This movement puts pressure on the drywall. The paper and compound cannot stretch, so cracks form.
Temperature changes also play a big role. The wood behind the drywall expands in warm months and contracts in winter. This movement creates stress on the seams.
What cracks look like
• thin hairline cracks along seams
• vertical cracks near door frames
• wider cracks that look like a split
• ceiling cracks caused by sagging or shifting joists
When cracks are serious
If you fix a crack and it returns again, the seam was not taped properly. You may need a drywall repair service to remove the bad tape, retape the joint, and reapply compound correctly.
If cracks continue to grow, it could be a structural issue. A professional should inspect it.
2. Moisture Damage in Walls and Ceilings
Moisture is the biggest enemy of drywall. Older Canadian homes face more moisture problems because of aging roofs, older plumbing systems, poor insulation, and cold winters that create condensation.
Where moisture comes from
• roof leaks
• plumbing leaks inside walls
• ice dams on the roof that melt into the home
• basement humidity
• poorly sealed windows
• bathroom steam without ventilation
What moisture damage looks like
• yellow or brown stains
• bubbling paint
• peeling drywall paper
• soft or spongy spots
• musty smell
• sagging ceilings
If moisture damage spreads, mold can form inside the wall. This is not safe to leave untreated.
Why moisture damage is dangerous
Wet drywall loses its strength. It sags, breaks, and becomes a breeding ground for mold. In older homes, small leaks can hide behind walls for years, making the damage worse.
Replacement is often the only solution. This involves cutting out the damaged area and installing new drywall boarding. After that, drywall finishing is needed to match the texture and repaint.
3. Settlement Problems That Affect Drywall
Older Canadian homes settle a lot more than new ones. The soil shifts from frost, thawing, moisture levels, and natural aging of the structure.
Settlement causes several drywall problems:
Cracks in corners
The corners show stress very quickly because they connect two pieces of drywall.
Gaps between walls and ceilings
If the ceiling joists move differently from the walls, gaps open up.
Popped screws and nails
Fasteners loosen as the framing shifts and push through the drywall surface.
Misaligned seams
Over time, seams that were once smooth become slightly uneven.
Uneven surfaces
If one part of the wall shifts more than the other, the drywall forms waves or bulges.
Settlement problems may look scary, but many of them can be fixed with the right tape, compound, and sanding work. A drywall repair service that understands older homes can restore these areas so they look clean and smooth again.
4. Bad Taping or Patching from Past Owners
Many drywall problems in older homes have nothing to do with age. They come from poor repairs made years ago. Homeowners who try to fix cracks or holes without the right tools or skills often create bigger problems.
Here are the most common taping and finishing mistakes:
Tape lifting or peeling
If the joint compound was not applied properly or if the wall was dusty, the tape separates from the surface.
Thick seams that show through paint
Too much compound or uneven spreading makes seams visible, especially with bright lighting.
Bumpy or rough texture
Improper sanding or cheap materials leave the wall uneven.
Patches that do not blend in
If a homeowner repairs a hole but does not feather the edges, the patch stands out.
Visible lines under paint
This usually means poor finishing or improperly applied tape.
Wrong texture applied to a patch
Different rooms in older homes often have different textures. If the repair does not match the original surface, it becomes obvious.
When homeowners try a DIY repair without experience, the damage often becomes worse. Fixing poor finishing requires removal of the old work and proper drywall installation to create a smooth, flawless surface.
5. Nail Pops and Screw Pops
Older homes commonly show nail pops. These are small round bumps that appear on walls or ceilings. They happen because the wood framing behind the drywall expands and contracts over time.
Why pops happen
• wood shifting
• old nails losing grip
• temperature changes causing movement
• vibrations from everyday living
What they look like
• small bumps under the paint
• cracked circles around fasteners
• nails slightly sticking out of the drywall
The solution is not to hammer them back in. A drywall repair service removes the old fastener, installs a proper screw, and patches the area so it stays secure.
6. Sagging Ceilings or Bulging Walls
Sagging or bulging drywall is a sign of deeper problems. This is common in older Canadian homes with moisture issues, structural shifting, or past water leaks.
Causes
• wet insulation weighing down the ceiling
• poor drywall installation
• water damage
• old drywall that has weakened
• improper framing or spacing
What it looks like
• a ceiling that curves downward
• walls that look swollen
• seams that look raised instead of flat
• paint separating from the drywall surface
This requires immediate professional attention. The damaged sections may need removal and new drywall boarding for safety. Trying to repair this with a simple patch will not work.
7. Holes, Dents, and Wear and Tear
Drywall is durable but not indestructible. Older homes often accumulate:
• dents from furniture
• holes from door handles
• old repairs that were not patched correctly
• scuffs from years of movement
• damage from renovations
Small holes are easy to fix, but older homes often have deeper or larger damage due to repeated repairs. Proper drywall installation and finishing is needed to make these areas look new again.
8. Unfinished or Poorly Finished Basements
Many older Canadian homes have basements that were finished long ago or never finished properly at all. Drywall in basements is more vulnerable because it sits near concrete, plumbing, and moisture.
Common problems in older basements include:
• moisture stains
• mold behind drywall
• poor framing
• badly installed boarding
• cracks from foundation settling
• uneven surfaces
Basements often require fresh drywall boarding and proper drywall finishing to restore a clean, safe space.
How to Prevent Drywall Problems in Older Homes
You cannot stop aging, but you can protect your walls.
Improve ventilation
Use fans, open windows, and install proper exhaust in bathrooms and kitchens.
Control moisture
Fix leaks quickly. Use dehumidifiers in basements. Seal windows.
Upgrade insulation
Better insulation reduces temperature swings that cause drywall stress.
Avoid DIY repairs
Professional finishing gives clean, long lasting results.
Keep an eye on cracks
If cracks keep returning, the seam needs a full retaping.
When to Call a Drywall Professional
You should contact a drywall repair service if you see:
• stains or soft areas
• bulges or sagging
• peeling tape
• mold or musty smells
• cracks that keep coming back
• visible seams after painting
• holes or dents that ruin the wall surface
Older Canadian homes need proper care. Expert drywall installation and finishing restores the home and protects your investment.
