Understanding Water Damage in Drywall
Water damages drywall faster than you might think. High humidity affects its structure over time. The porous nature of drywall lets moisture damage it easily. This can lead to costly repairs if you don’t fix it fast.
What causes water damage in drywall?
Plumbing leaks cause most drywall water damage. Hidden leaks form inside walls because of deteriorating pipes, burst plumbing, or shifting property structures. Water seeps from above into ceilings and walls because of roof problems like damaged shingles, faulty flashing, or clogged gutters.
Bathrooms and kitchens don’t deal exceptionally well with poor ventilation that creates condensation on wall surfaces. The porous drywall absorbs moisture if there’s no proper airflow. Natural disasters, plumbing failures, and broken appliances like dishwashers, washing machines, and water heaters can also destroy drywall’s integrity.
Signs your drywall has water damage
You can save money on Toronto drywall installation and repairs by spotting water damage early. Look out for these warning signs:
- Discoloration: Yellow, brown, or dark stains on walls or ceilings show moisture has gotten in
- Soft or spongy texture: Damaged drywall feels soft and sinks when you press it
- Peeling paint or wallpaper: Moisture breaks down adhesives and causes bubbling, cracking, or flaking
- Warping or bulging: Water absorption makes surfaces uneven or causes sections to sag
- Visible mold growth: Black, green, or white patches with musty odors mean the damage is getting worse
Why water-damaged drywall needs urgent repair
Wet drywall loses its strength fast and becomes soft and weak. Affected walls start sagging, making your home unsafe. Quick water damage repairs stop these structural problems from getting worse.
Wet drywall creates perfect conditions for mold that can start growing within 24-48 hours after getting wet. This can be dangerous to your family’s health by causing breathing problems, allergies, and other health issues.
Small drywall repairs can become much more expensive if you wait too long. Water damage spreads to bigger areas and causes other problems. You need to act quickly.
Water-damaged drywall that stays wet for several days needs major water damage repairs. This includes any insulation behind it.

Types of Water Damage and Their Repair Costs

with most jobs around CAD 4876.76. Small mold problems cost CAD 696.68 to CAD 1393.36, but large infestations can reach CAD 41800.81. The price tag for replacing moldy drywall runs CAD 1393.36 to CAD 16720.32.
Ceiling vs. wall water damage
Ceiling repairs cost more than walls because they’re trickier and need extra safety measures. The price for ceiling repair ranges from CAD 627.01 to CAD 2229.38 and takes 2-3 days. Wall repairs cost less, between CAD 418.01 and CAD 1184.36.
Structural damage behind drywall

Wet insulation replacement costs can vary. For fiberglass, it costs CAD 0.70 to CAD 1.39 per square foot. For spray foam, the cost is CAD 2.09 to CAD 4.18 per square foot.
DIY vs. Professional Drywall Toronto Repair
Water-damaged drywall leaves homeowners with a vital decision: should they fix it themselves or call a professional? The answer depends on how bad the damage is and their DIY skills.
When DIY is possible
Minor damage scenarios work best for DIY drywall installation and repair. Small dents, hairline cracks, and nail-repair drywall holes will cost between CAD 13.93 and CAD 69.67 if you fix them yourself. Surface damage with limited water exposure makes a perfect candidate for DIY repairs. You’ll save on labour costs that make up 65-75% of total repair expenses.
Tools and materials needed for DIY
A successful DIY repair requires:
- Drywall repair kit (CAD 13.93-18.11)
- Joint compound (approximately CAD 11.15)
- Putty knife or trowel (about CAD 20.90)
- Sandpaper (120-grit recommended)
- Drywall saw and tape
Risks of DIY Drywall water damage repair
DIY drywall water damage repair comes with serious risks. Poor repair techniques lead to recurring problems and higher costs down the road.
DIY attempts without proper safety equipment can expose you to mold. The EPA reports that mold starts growing 24-48 hours after water exposure. This makes quick professional help vital for major damage.
Benefits of hiring a drywall repair professional
Professional contractors have specialized expertise and equipment most homeowners don’t have. They charge CAD 55.73 to CAD 139.34 per hour or offer project-based pricing that gives clearer cost expectations.
These experts use advanced tools like moisture meters and infrared cameras to spot hidden moisture. This prevents future mold problems. Many professionals also back their work with warranties and guarantees.
How to estimate drywall repair cost accurately
Automated software tools give the most accurate cost projections. You’ll need exact measurements of damaged areas, material lists, and labour quantities for best results. Getting at least three professional quotes will ensure fair pricing.

Factors like damage severity, affected area size, and repair timeline significantly influence the final price.

The repair time depends on the extent of the damage. Minor repairs can often be completed in a day, while more extensive damage might take 2-4 days. For instance, replacing multiple panels typically takes 1-2 days, while full wall replacement can require 3-4 days.

Check for discolouration like yellow, brown, or dark stains. Feel for a soft or spongy texture when pressed.
Look for peeling paint or wallpaper. Notice any warping or bulging on the wall surface.
Also, watch for visible mold growth. If you notice any of these signs, it’s important to address the issue promptly to prevent further damage.
