Q: Why is my ceiling cracking where it meets the wall?

• <div><p>Common causes of ceiling cracks along drywall seams include poor drywall installation techniques, structural issues, truss uplift, and foundation problems. Temperature and humidity also play major roles in ceiling cracks flush with the wall. As the drywall shrinks and expands from major temperature changes or extreme humidity shifts, this can cause the drywall to crack.</p></div>

Q: Can I do my own plastering?

• <div><p>It is possible to apply plaster on the interior or exterior of your home, but we don&rsquo;t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it&rsquo;s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it&rsquo;s usually the best option to achieve high-quality results.</p></div>

Q: Can I repair ceiling cracks on my own?

Plaster Repair questions, answered by experts

Common causes of ceiling cracks along drywall seams include poor drywall installation techniques, structural issues, truss uplift, and foundation problems. Temperature and humidity also play major roles in ceiling cracks flush with the wall. As the drywall shrinks and expands from major temperature changes or extreme humidity shifts, this can cause the drywall to crack.

All plaster walls will crack over time due to normal house settling and expansion and contraction from temperature and moisture changes. Small, thin hairline cracks are generally not serious and are mostly a cosmetic issue. However, larger or more significant cracks can indicate structural problems.

Here's how to tell the difference:

Cosmetic Cracks: Cracks that are 0.5 cm (0.2 inches) or thinner are typically cosmetic.
Structural Cracks: Cracks wider than 0.5 cm, excessive or deep cracks, multiple cracks in the same area, or cracks that span around corners can signify a structural or foundation issue. Cracks along the joints where walls meet the ceiling also warrant attention.

For cracks wider than 0.5 cm, structural repair is needed. If a crack is 2.5 cm (1 inch) or wider, or if you notice any signs of a structural problem, it is best to contact a plaster repair professional to assess the damage.

Look for flaking paint or air bubbles that burst and then flake away. Paint will begin to flake after being exposed to minimal moisture or water, so it’s a good indicator of any water damage. If you notice your paint starting to flake, feel the plaster underneath to see if it is soft or damp.
