How to Prevent and Fix Drywall Cracks
August 3, 2024
Drywall cracks are a common issue that many homeowners face, but with the right approach, they can be prevented and repaired effectively. At Barrie Drywallers, we understand the importance of maintaining the integrity and appearance of your walls. In this article, we'll guide you through the causes of drywall cracks, how to prevent them, and the best methods for fixing them.
Causes of Drywall Cracks
Understanding the root causes of drywall cracks is crucial in preventing them. Here are some common reasons why drywall may crack:
- Settlement of the House: As a house settles over time, minor shifts can cause stress on the drywall, leading to cracks.
- Temperature and Humidity Fluctuations: Changes in temperature and humidity levels can cause the drywall to expand and contract, resulting in cracks.
- Poor Installation: If the drywall was not installed properly, with inadequate fastening or poorly applied joint compound, cracks can develop.
- Structural Issues: Problems with the foundation or framing of the house can create stress on the walls, leading to cracks.
- Impact or Damage: Accidental impacts or excessive force on the walls can cause cracks to form.
How to Prevent Drywall Cracks
Prevention is the best way to deal with drywall cracks. Here are some tips to help you keep your walls in top condition:
- Control Humidity Levels: Maintain a consistent humidity level in your home to prevent expansion and contraction of the drywall. Use dehumidifiers in the summer and humidifiers in the winter if necessary.
- Proper Installation: Ensure that your drywall is installed by professionals who follow best practices, such as using the correct fasteners and applying joint compound properly.
- Allow for Settlement: When constructing a new home, allow for some settlement by using flexible materials at joints and corners.
- Regular Maintenance: Inspect your walls regularly for any signs of stress or damage, and address issues promptly to prevent them from worsening.
- Address Structural Issues: If you notice cracks that seem to be caused by structural problems, consult a professional to address the underlying issues.
How to Fix Drywall Cracks
If you already have drywall cracks, follow these steps to repair them effectively:
Materials Needed
- Utility knife
- Sandpaper (120-grit)
- Joint compound
- Drywall tape (paper or mesh)
- Putty knife
- Primer and paint
Step-by-Step Repair Process
- Prepare the Area:
- Use a utility knife to widen the crack slightly, creating a V-shape. This helps the joint compound adhere better.
- Sand the area around the crack to create a smooth surface for the repair.
- Apply Joint Compound:
- Apply a thin layer of joint compound over the crack using a putty knife.
- Place drywall tape over the compound, pressing it firmly into place.
- Apply another layer of joint compound over the tape, smoothing it out to blend with the surrounding wall.
- Sand and Repeat:
- Once the compound is dry, sand it lightly to remove any bumps or ridges.
- Apply a second layer of joint compound, feathering the edges to create a seamless repair.
- Sand again once dry, and apply a final, thin layer of compound if necessary.
- Prime and Paint:
- After the final layer of compound is dry and smooth, apply a coat of primer to the repaired area.
- Once the primer is dry, paint the wall to match the rest of the room.

Drywall cracks can be an eyesore and, if left unchecked, can lead to more significant issues. By understanding the causes, taking preventive measures, and knowing how to repair cracks effectively, you can keep your walls looking pristine.

Installing drywall is a key step in transforming any space, whether it’s a new construction project or a home renovation. However, the success of drywall installation largely depends on how well the walls are prepared beforehand. At Barrie Drywallers , we know that proper preparation is the foundation of a smooth and efficient installation process. Here's a step-by-step guide to getting your walls ready for drywall installation . 1. Clear the Area Before you begin, ensure that the workspace is clean and clutter-free. Move furniture, cover floors with drop cloths, and remove any obstacles that might hinder the installation process. Why This Matters: A clean and open workspace minimizes the risk of damage and allows installers to work efficiently. 2. Inspect the Walls Carefully examine the walls for any issues that could affect the drywall installation, such as cracks, water damage, or uneven surfaces. What to Look For: Cracks or Holes: Repair these to provide a stable surface. Moisture or Mold: Address these issues immediately to prevent future damage. 3. Address Insulation Needs If your walls lack proper insulation, now is the time to install or upgrade it. Adequate insulation not only improves energy efficiency but also enhances soundproofing. Pro Tip: In areas prone to moisture, like basements, consider using moisture-resistant insulation materials. 4. Ensure Proper Framing Check that the wall studs are properly spaced and securely installed. The standard spacing for studs is 16 or 24 inches apart. Ensure they are level and aligned to avoid uneven drywall. Tools You’ll Need: Level: To check for straightness. Measuring Tape: To confirm correct spacing. 5. Install Vapor Barriers In areas like basements or bathrooms, adding a vapor barrier is crucial to prevent moisture from seeping into the walls. Material Options: Plastic Sheets: Cost-effective and easy to install. Specialized Paints: Ideal for areas requiring a seamless application. 6. Pre-Plan Electrical and Plumbing If your project involves electrical wiring or plumbing, make sure all these elements are installed and secured before drywall installation. Mark their locations clearly on the studs to avoid accidentally covering access points. What to Check: Ensure electrical boxes are flush with the intended drywall surface. Verify that plumbing pipes are securely anchored. 7. Clean and Prime the Surface Dust and debris on the walls can interfere with drywall adhesion. Use a broom, vacuum, or cloth to thoroughly clean the wall surface. Optional Step: Apply a primer to improve the adherence of joint compounds and paint after the drywall is installed. 8. Gather the Right Tools Having the necessary tools and materials on hand ensures a smooth installation process.

When it comes to drywall, the materials you choose can significantly impact your home's durability, appearance, and functionality. For homeowners and contractors in Barrie, Ontario, who prioritize quality and longevity, solid gypsum sheets stand out as a superior choice. At Barrie Drywallers , we believe in using only the best materials to provide flawless results that last for years. What Are Solid Gypsum Sheets? Solid gypsum sheets are drywall panels made primarily of gypsum, a natural mineral prized for its strength, fire resistance, and versatility. These sheets are sandwiched between layers of durable paper or fiberglass, resulting in a sturdy and reliable construction material suitable for various applications. Key Benefits of Solid Gypsum Sheets 1. Exceptional Durability Gypsum is naturally resilient, making solid gypsum sheets resistant to cracking and wear. This durability ensures that your walls and ceilings can withstand daily stresses, whether in a high-traffic residential area or a busy commercial space. 2. Superior Fire Resistance Safety is paramount, and solid gypsum sheets excel in fire resistance. Gypsum contains water in its mineral structure, which is released as steam when exposed to heat, slowing the spread of flames. Many solid gypsum sheets are fire-rated, making them an ideal choice for homes and businesses prioritizing safety. 3. Enhanced Soundproofing For those looking to create quiet, peaceful spaces, gypsum sheets are an excellent option. Their dense composition helps reduce noise transmission between rooms, making them perfect for offices, bedrooms, or entertainment areas. 4. Moisture and Mold Resistance In a climate like Barrie’s, where humidity levels can vary, moisture-resistant gypsum sheets are invaluable. These sheets are treated to resist water absorption, reducing the risk of mold and mildew growth in areas like bathrooms, basements, and kitchens. 5. Smooth and Versatile Finishing Solid gypsum sheets provide a smooth, even surface, perfect for painting, texturing, or wallpapering. Their versatility ensures a professional finish for any design style. Applications of Solid Gypsum Sheets Solid gypsum sheets are versatile and can be used in: Residential projects: Ideal for walls and ceilings in living rooms, bedrooms, and kitchens. Commercial spaces: Perfect for offices, retail stores, and restaurants needing durability and fire safety. Specialty areas: Moisture-resistant sheets are excellent for bathrooms and basements, while soundproofing options enhance theaters and recording studios. Why Choose Solid Gypsum Sheets Over Other Drywall Options? While there are various drywall options available, solid gypsum sheets stand out due to their: Longevity: Fewer repairs and replacements over time. Safety: Increased fire and mold resistance. Eco-Friendliness: Many gypsum sheets are recyclable and made with sustainable materials. Cost-Effectiveness: While slightly more expensive initially, their durability saves money in the long run.

Drywall finishing is an essential step in any renovation or construction project. Whether you’re remodeling a single room or building a new home, achieving a smooth and polished look with drywall finishing can make all the difference in the final appearance of your space. At Barrie Drywallers , we understand that a high-quality drywall finish not only enhances the aesthetics of your property but also adds value and durability. In this article, we’ll walk you through the process of drywall finishing , breaking down each step to help you achieve professional results. What is Drywall Finishing? Drywall finishing involves applying joint compound (often called "mud") to the seams, joints, and screw holes of drywall sheets to create a smooth, seamless surface. The goal is to make the walls or ceilings ready for painting, texturing, or wallpapering. This process includes several stages, from applying the initial coat of compound to sanding and priming for a flawless finish. Why is Drywall Finishing Important? Aesthetic Appeal : A well-finished wall enhances the overall look of your home or office. Durability : Proper finishing helps protect the drywall from damage and wear over time. Value Addition : High-quality drywall finishing can increase the resale value of your property. The 5 Levels of Drywall Finishing Before diving into the step-by-step process, it’s helpful to understand the different levels of drywall finishing. The levels range from 0 to 5 , each representing a different degree of smoothness and readiness for paint: Level 0 : No finishing. Drywall is simply hung without any mud or tape. Level 1 : A single coat of joint compound over the tape. Often used in hidden areas like attics. Level 2 : Two coats of compound. Suitable for garages and utility spaces. Level 3 : Three coats of compound. Used for surfaces that will receive a heavy texture. Level 4 : Three coats, plus a light sanding. Ideal for walls that will be painted with a flat or satin finish. Level 5 : The highest level, with a skim coat applied for a perfectly smooth surface, ready for high-gloss paint or critical lighting. For most residential spaces, Level 4 is standard, but Level 5 is recommended for high-end finishes and areas with strong natural or artificial light. Step-by-Step Guide to Drywall Finishing Step 1: Preparation and Inspection Before you start, inspect the drywall installation to ensure all screws are properly set and the panels are securely attached. Remove any dust, debris, or protruding screws that could interfere with the finishing process. Tools Needed : Screwdriver, utility knife, sanding block. Tip : Use a shop vac to clean up dust from drywall surfaces for better compound adhesion. Step 2: Applying Drywall Tape Start by applying a layer of joint compound along the seams between drywall panels. Then, press paper or mesh tape into the wet compound to reinforce the joints. Paper Tape : Provides a stronger hold and prevents cracks. Mesh Tape : Easier to work with, especially for beginners, but may require more compound. Smooth out the tape using a 6-inch drywall knife , removing any excess compound to create a flat surface. Step 3: First Coat of Joint Compound (Mudding) Once the tape is in place, apply the first coat of joint compound over all seams, corners, and screw holes. Use a 10- to 12-inch drywall knife to feather the edges, ensuring a smooth transition between the compound and the drywall surface. Tip : Apply the compound in thin layers to avoid cracking and reduce drying time. Drying Time : Allow 24 hours for the compound to dry completely before moving to the next step. Step 4: Second Coat of Joint Compound After the first coat is completely dry, lightly sand the surface with a sanding sponge or fine-grit sandpaper to remove any ridges or bumps. Wipe away dust with a damp cloth. Apply a second coat of compound, extending it a few inches beyond the edges of the first coat to create a wider, more seamless blend. Use a larger drywall knife for this step to achieve a smoother finish. Step 5: Third Coat of Joint Compound The third coat, also known as the final coat , is applied to perfect the surface. This coat should be even thinner than the previous ones, focusing on filling in any remaining imperfections. Tip : Feather the edges as much as possible to avoid visible lines after painting. Drying Time : Again, let it dry for 24 hours before sanding. Step 6: Sanding the Surface Once the final coat is dry, it’s time to sand the entire surface to achieve a smooth finish. Use a sanding pole or a sanding block with fine-grit sandpaper for best results. Tip : Use a light source to check for imperfections. Hold a work light at an angle against the wall to highlight any uneven areas. Safety : Wear a dust mask and safety goggles to protect yourself from drywall dust. Step 7: Applying a Primer The last step in drywall finishing is applying a drywall primer to seal the surface and prepare it for paint. Priming helps paint adhere better and provides a uniform appearance. Tools Needed : Roller, paintbrush, primer. Tip : Use a high-quality primer to prevent flashing (uneven sheen) in the final paint job. Common Drywall Finishing Mistakes to Avoid Skipping the Primer : Not priming the walls can result in uneven paint coverage. Rushing the Drying Time : Applying additional coats before the previous one is fully dry can lead to cracks and bubbles. Using the Wrong Tape : Paper tape is best for flat seams, while mesh tape is better for patching small holes. Why Choose Barrie Drywallers for Your Drywall Finishing Needs?
