Updating a brick house exterior is one of the most impactful renovations a homeowner can undertake, dramatically improving curb appeal and long-term value. While brick is renowned for its durability, the finish can fade, crack, or stain over decades of exposure to the elements. This guide walks you through the essential steps to assess, prepare, and transform your home’s facade with confidence and precision.
Evaluating the Current Condition of Your Brick
Before any work begins, a thorough inspection is non-negotiable. Look for signs of structural integrity issues, such as cracked or crumbling mortar, bricks that are chipped or spalling, and any significant shifting in the foundation. These are not just cosmetic concerns; they are indicators of deeper problems that must be addressed before applying a new finish. Take detailed photographs and notes, focusing on areas where water might be infiltrating, such as around windows, doors, and rooflines.
Common Issues to Identify
- Mortar joints that are powdery or missing, which compromise the wall's stability.
- Efflorescence, a white salt residue that signals moisture problems within the brick.
- Vegetation growth, like moss or ivy, which retains moisture and can cause brick decay.
The Benefits of a Fresh Exterior Finish
Modern siding options provide benefits that brick alone cannot, including superior insulation and reduced maintenance. Fiber cement siding, in particular, has become a popular choice for updating the look of a brick house. It mimics the texture and color of traditional lap siding or clapboard while offering the brick protection from rot, insects, and weathering. This combination allows you to retain the classic charm of brick while gaining the efficiency and versatility of contemporary materials.

The Critical Step: Pressure Washing
Surface preparation is where the success of the project is decided. A professional-grade pressure washer is the most effective tool for blasting away decades of dirt, mold, and airborne pollutants that have settled into the brick. Aim for a pressure setting between 500 and 1000 PSI to avoid damaging the brick surface. Hold the wand at a 45-degree angle, moving consistently across the surface to ensure a clean, uniform profile that will help the new materials bond securely.
Repairing Mortar Joints
Once the wall is clean and dry, turn your attention to the mortar. Tuck pointing is the process of filling in deteriorated mortar joints with a fresh, weather-resistant compound. This step is vital for sealing out moisture and stabilizing the wall. Use a color-matched mortar mix and ensure the new joints are compacted firmly to create a consistent, weather-tight barrier that aligns with the existing aesthetic.
Priming and the Application of New Materials
With repairs complete, the surface is ready for priming. A high-quality bonding primer ensures that the new siding adheres evenly and prevents any alkalinity from the brick from bleeding through. When installing fiber cement or other composite materials, start from the bottom of the wall and work your way upward. Pay close attention to the detailing around windows and doors, using premium flashing and sealant to create a watertight envelope that protects the structure for years.

Making a Lasting Investment
Updating a brick house exterior is more than a cosmetic upgrade; it is a strategic investment in the longevity and marketability of your home. The combination of restored brickwork and modern siding creates a layered, dimensional look that is both timeless and current. By following these steps, you ensure that your renovation delivers maximum return on investment while protecting the heart of your home from the elements.
