Why Consider Metal Siding Over Brick?
Upgrading your home’s exterior is a significant undertaking, and choosing metal siding over brick offers a compelling list of advantages. It’s more than just a cosmetic change; it’s an investment in your home’s future.
Aesthetic Transformation
Metal siding provides a sleek, modern aesthetic that can dramatically update your home’s curb appeal. You can choose from a wide range of colors, profiles, and finishes. This allows for significant design flexibility, from contemporary vertical panels to classic horizontal styles. It’s a fantastic way to revitalize a tired-looking brick facade.
Enhanced Durability and Low Maintenance
Unlike brick, which can spall, crack, or require tuckpointing over time, metal siding is incredibly durable. It resists rot, pests, and fire, and generally requires very little upkeep beyond occasional cleaning. This means less time on maintenance and more time enjoying your home.
Improved Energy Efficiency
When installed correctly with a proper furring system, metal siding creates a vented rainscreen. This air gap, combined with optional insulation, can significantly improve your home’s thermal performance. It helps reduce heat transfer, potentially lowering your heating and cooling costs.
Protection Against the Elements
Metal siding offers superior protection against harsh weather conditions. It stands up well to wind, hail, and heavy rain. The integrated flashing and drainage plane system prevents moisture from penetrating your home’s structure.
Assessing Your Existing Brick Foundation
Before you even think about fasteners and panels, a thorough inspection of your current brick wall is non-negotiable. This step is critical for a long-lasting and problem-free installation. Don’t skip it!
Inspecting for Damage and Stability
Walk around your entire home and carefully examine the brickwork. Look for:
- Cracks in the mortar joints or bricks themselves.
- Loose or crumbling bricks.
- Areas where the brick might be pulling away from the foundation.
- Any signs of structural instability.
If you find significant structural damage, consult a structural engineer or a qualified masonry contractor first. Installing siding over a compromised wall will only mask, and potentially worsen, underlying issues.
Addressing Moisture Issues and Weep Holes
Moisture is the enemy of any exterior cladding system.
- Identify any areas with persistent dampness, mold, or efflorescence (white, powdery residue) on the brick.
- Ensure all existing weep holes at the base of the brick are clear and functional. These are essential for allowing moisture to escape from behind the brick.
- If you find significant moisture problems, you must address the source before proceeding. This might involve gutter repair, grading improvements, or foundation sealing.
Ensuring a Level Surface
Brick walls, especially older ones, are rarely perfectly flat. Metal siding requires a relatively plumb and level surface for a professional finish.
- Use a long level or a straightedge to check the wall’s flatness.
- Note any significant bulges or depressions.
- You’ll primarily correct these variations with your furring strip system, but understanding the extent of unevenness upfront is helpful.
Essential Materials and Tools for the Job
Having the right materials and tools on hand makes all the difference in a DIY project. Don’t start without a complete shopping list and a fully stocked workshop.
Siding Panels and Fasteners
- Metal Siding Panels: Choose your desired profile (e.g., corrugated, standing seam, board and batten look) and material (steel, aluminum). Consider the gauge (thickness) for durability.
- Starter Strips: These provide a secure base for the first row of siding.
- Corner Trim: Internal and external corners create a finished look and protect edges.
- J-Channel/F-Channel: Used around windows, doors, and for terminating siding sections.
- Metal Screws/Fasteners: Corrosion-resistant, self-tapping screws designed for metal siding. Ensure they are long enough to penetrate the furring strips and securely into the brick or masonry anchors.
Furring Strips and Flashing
- Furring Strips: Typically 1×3 or 1×4 pressure-treated lumber, or metal hat channel. These create the air gap and provide an attachment point.
- Masonry Anchors/Screws: For securely attaching furring strips to brick (e.g., Tapcon screws, sleeve anchors).
- House Wrap/Vapor Barrier: A breathable, water-resistive barrier (WRB) to go over the brick.
- Flashing: Metal coil stock or pre-bent flashing for windows, doors, and the base of the wall. This is crucial for directing water away.
- Drip Edge: Installed at the top of the wall and above openings to direct water.
Insulation and House Wrap
- Rigid Insulation (Optional): If you’re aiming for maximum energy efficiency, rigid foam insulation boards can be installed between the furring strips.

Step-by-Step Guide to Installing Metal Siding Over Brick
This is where your vision starts to become a reality. Take your time with each step, paying close attention to detail, especially regarding moisture management.
Step 1: Thorough Surface Preparation
First, clean the brick surface thoroughly.
- Remove any loose mortar, dirt, or debris with a stiff brush or power washer (allow to dry completely).
- Repair any minor cracks or holes in the brick or mortar. Use a masonry repair caulk or mortar patch.
- Ensure all weep holes are clear.
Next, install your house wrap.
- Starting from the bottom, unroll and attach the house wrap directly over the clean brick.
- Overlap horizontal seams by at least 6 inches, shingle-style (upper layer over lower layer).
- Overlap vertical seams by at least 12 inches.
- Secure the house wrap with cap nails or staples, ensuring it’s taut but not stretched.
- Flash around all windows and doors with appropriate self-adhering flashing tape.
Step 2: Installing Your Drainage Plane and Furring Strips
This is the backbone of your new siding system and crucial for proper moisture management.
- Mark the location for your furring strips. They typically run vertically, spaced at 16 or 24 inches on center.
- Start by installing a horizontal starter strip at the bottom of the wall, ensuring it’s perfectly level. This provides a level base for your vertical strips.
- Attach vertical furring strips to the brick using masonry anchors or screws. Pre-drill pilot holes through the furring strips and into the brick.
- Use shims behind the furring strips as needed to create a perfectly plumb and flat surface. A long level is your best friend here.
- Ensure a minimum 1/4-inch gap between the bottom of the lowest furring strip and the foundation for drainage.
Step 3: Adding Insulation (Optional but Recommended)
If you chose to add rigid insulation, now is the time.
- Cut rigid foam insulation boards to fit snugly between your vertical furring strips.
- Press them into place against the house wrap.
- You can secure them with a few dabs of construction adhesive or additional long screws that penetrate into the furring strips.
Step 4: Installing Starter Strips and Corner Trim
With your furring system in place, it’s time for the trim.
- Install your metal siding starter strip along the bottom of the wall, perfectly level and aligned with the lowest furring strip.
- Attach exterior corner posts and interior corner channels. Ensure they are plumb.
- Install J-channel or F-channel around all windows and doors, sloping the bottom piece slightly for drainage.
Step 5: Cutting and Fastening Metal Siding Panels
Now for the main event: installing the metal siding over brick.
- Start at a corner, typically the back of the house, and work your way around.
- Place the first panel into the starter strip and secure it to the furring strips with your corrosion-resistant fasteners.
- Ensure fasteners are driven straight and not overtightened, allowing for thermal expansion and contraction of the metal.
- Overlap panels according to the manufacturer’s instructions. This usually involves a side lap for horizontal panels.
- Use your metal shears or circular saw with a metal blade for precise cuts. Always wear appropriate PPE.
Step 6: Detailing Around Openings and Finishing Touches
- When you reach windows or doors, measure and cut the siding panels to fit precisely into the J-channels.
- Install any necessary utility boxes or mounting blocks for exterior lights or outlets.
- Apply high-quality exterior sealant where appropriate, such as around windows and doors, to prevent water intrusion.
- Install ridge cap or trim pieces along the top edge of the siding where it meets the soffit or roofline.
Crucial Considerations and Potential Challenges
While installing metal siding over brick is a rewarding project, there are specific details that demand your careful attention. Overlooking these can lead to future problems.
Managing Moisture and Ventilation
A common concern when considering metal siding over brick is ensuring proper moisture management. The furring strip system creates a critical air gap behind the siding. This gap, often referred to as a “rainscreen,” allows any moisture that gets past the siding to drain down and out through the base. It also promotes ventilation, helping to dry out the wall structure. Ensure your weep holes at the bottom remain clear and functional after installation.
Dealing with Uneven Brick
As mentioned, brick walls are rarely perfectly flat. The key to a professional-looking metal siding installation is creating a consistently plumb and level surface with your furring strips.
- Use a long level and shims strategically behind the furring strips.
- Don’t be afraid to take your time adjusting and checking for flatness.
- A laser level can be incredibly helpful for establishing plumb lines.
Electrical Outlets and Exterior Fixtures
You’ll need to extend any existing electrical outlets, spigots, or light fixtures through the new siding.
- Use weather-rated extension boxes or mounting blocks designed for exterior use.
- Ensure all penetrations are properly sealed with caulk and flashing to prevent water intrusion.
- Always disconnect power at the breaker before working on electrical components.
Working with Different Metal Siding Profiles
Metal siding comes in various profiles:
- Corrugated panels offer a classic, industrial look.
- Standing seam panels provide a clean, modern aesthetic with concealed fasteners.
- Board and batten style metal siding mimics traditional wood siding.
Each profile has specific installation requirements for overlapping and fastening. Always refer to the manufacturer’s instructions for your chosen siding type. Understanding the long-term benefits and potential challenges of installing metal siding over brick will help you make informed decisions.
Safety First: Protecting Yourself During Installation
DIY projects are incredibly rewarding, but safety should always be your top priority. Working with metal, at heights, and with power tools demands vigilance.
Personal Protective Equipment (PPE)

- When using metal shears, ensure your hands are clear of the cutting path.
- If using a circular saw with a metal cutting blade, wear a face shield in addition to safety glasses.
- Ensure there are no flammable materials nearby when cutting, as sparks can fly.
- Allow cut edges to cool before handling, as they can be very hot.
Frequently Asked Questions About Metal Siding Over Brick
Got more questions? We’ve got answers to some of the most common queries about this home improvement project.
How much does it cost to install metal siding over brick?
The cost varies significantly based on the type of metal siding (steel, aluminum, gauge), the complexity of your home’s exterior, labor rates if you hire a contractor, and regional pricing. DIY installation will save on labor, but materials alone can range from $3 to $10 per square foot or more. Factor in the cost of furring strips, house wrap, flashing, and fasteners as well.
Do I need a vapor barrier when installing metal siding over brick?
Yes, installing a high-quality, breathable house wrap (which acts as a water-resistive barrier or WRB) over the brick is crucial. This helps manage any moisture that might penetrate the siding and prevents it from reaching your brick or interior walls. It also provides an extra layer of protection against air infiltration.
Can I install metal siding directly onto brick?
No, you should not install metal siding directly onto brick. It is essential to create a furring strip system first. This system provides a crucial air gap for ventilation and drainage (the rainscreen effect), allows for shimming to create a plumb surface, and gives you a solid attachment point for the siding panels. Installing directly would trap moisture and lead to potential issues.
What types of metal siding are best for this application?
For residential use, common choices include steel and aluminum siding.
- Steel siding is very durable, impact-resistant, and comes in various profiles and finishes. It’s often heavier and might require more robust fastening.
