Drywall
What Are the Most Common Causes of Damage in Drywall?
Reviewed by Fadi Mamar, Co-founder
Drywall damage can occur for various reasons, from heavy-duty wear and tear to accidental impacts. No matter the cause, drywall damage can be unsightly and even pose a safety hazard if left unaddressed.
Before you can repair your drywall, it is essential to understand what caused its damage in the first place. Below are some of the most common causes of drywall damage.
What Can Cause Damage in Drywalls?
Drywall is one of the most common materials used in homes and businesses today. It’s also one of the most susceptible to damage. Here are some of the most common causes of drywall damage:
1. Water Damage
One of the most common causes of the drywall damage is water damage. Water can enter your home or business in many ways, such as leaks in the roof, windows, or walls. Once water enters your drywall, it can cause the paper backing to separate from the gypsum, leading to warping, crumbling, or mould growth.
2. Impact Damage
Another common cause of drywall damage is impact damage. This can be caused by many things, such as moving furniture, children playing, or even door knobs being slammed too hard. Impact damage can cause cracks, holes, or even complete breakage of your drywall.
3. Settling
As your home or business settles over time, it can cause cracks or holes in your drywall. These cracks or holes can allow water or pests to enter your home or business, which can cause further damage.
4. Poor Installation
If your drywall wasn’t installed properly, it could be more susceptible to damage. Poorly installed drywall can crack or break more easily than properly installed drywall.
5. Age
Over time, your drywall will begin to degrade and break down. This is a natural process and is to be expected. However, if your drywall is not properly maintained, it can accelerate the breakdown.
Working with a Contractor to Repair Drywall Damage
Hiring a contractor to repair your drywall can be a stressful experience. There are a lot of important factors to consider, such as cost, quality of work, and timing. But with a bit of research and preparation, you can find a great contractor who will do a great job repairing your drywall damage. Here are a few tips to help you find and work with a great contractor:
1. Get Multiple Quotes
When hiring a contractor, it's important to get multiple quotes. This way, you can compare prices and find the best value for your money.
2. Check Reviews
Before hiring a contractor, be sure to check reviews. Look for reviews from past clients to get an idea of the quality of work you can expect.
3. Ask for References
When you're considering a contractor, be sure to ask for references. This way, you can talk to past clients and get a feel for the quality of work you can expect.
4. Get Everything in Writing
When you hire a contractor, be sure to get everything in writing. This includes the scope of work, the price, and the timeline, as this will help ensure that there are no surprises down the road.
5. Communicate with Your Contractor
Once you've hired a contractor, communicate with them throughout the process. This way, you can stay up-to-date on the progress and address any concerns.
Conclusion
Drywall damage can be a serious problem, but it can be fixed relatively easily if you know what you're doing. The most important thing is to catch the problem early and take care of it before it worsens. If you have any concerns, be sure to consult a professional.

Frequently Asked Questions
What causes drywall damage?
Drywall damage in GTA homes is most commonly caused by moisture and water infiltration, which can stem from plumbing leaks, basement flooding, or roof issues. Physical impacts, such as accidental holes or dents, are also frequent culprits, along with settling of the home's foundation, which can cause cracks to form over time. Seasonal temperature and humidity fluctuations, which are significant in the Toronto area, can further cause drywall to expand and contract, leading to surface damage.
Can drywall dust cause headaches?
Yes, drywall dust can cause headaches, as it contains fine gypsum and silica particles that irritate the respiratory system and sinuses when inhaled. Prolonged exposure during renovation work can lead to sinus congestion, throat irritation, and headaches, particularly in poorly ventilated spaces. It is strongly recommended to wear an N95 respirator mask and ensure proper ventilation when sanding or cutting drywall in your home.
What are two common mistakes made during drywalling?
One of the most common mistakes is improper taping and mudding of seams, where insufficient joint compound or poor technique leads to visible cracks and bubbling over time. Another frequent error is failing to account for moisture in areas like bathrooms and kitchens by using standard drywall instead of moisture-resistant greenboard or cement board, which leads to mould growth and deterioration.
What does drywall damage look like?
Drywall damage can appear as visible cracks, often running horizontally, vertically, or diagonally across the surface, and may indicate structural settling or moisture issues. Water damage typically presents as yellowish-brown staining, bubbling paint, or soft and sagging sections of the wall or ceiling. Holes, dents, and crumbling edges from physical impact are also common signs of drywall damage found in GTA homes.
How to tell if drywall needs to be replaced?
Drywall should be replaced rather than repaired if it shows signs of significant water damage, such as persistent staining, softness, or visible mould growth, as these issues compromise both structural integrity and indoor air quality. Large holes greater than roughly 15 centimetres in diameter, or areas where the drywall is crumbling and no longer holds fasteners, also warrant full replacement. If you notice a musty odour emanating from walls, this is a strong indicator of hidden mould and you should have the drywall professionally inspected immediately.
