If you live in New Jersey and have an older stucco home, you might be wondering – can you put siding over stucco to give it a fresh, updated look? The short answer is yes, but there’s more to it than simply nailing siding onto the wall.
Done right, siding over stucco can improve curb appeal, protect your home from weather, and even boost energy efficiency. Done wrong, it can trap moisture, cause hidden damage, and cost you more in the long run.
This guide covers everything homeowners need to know before deciding, from the best siding materials to installation steps, costs, climate considerations, and expert tips.
Can You Put Siding on a Stucco House?
Yes, you can put siding on a stucco house, but proper preparation is critical. The stucco must be:
- Structurally sound – no major cracks, bulges, or loose areas
- Dry – no hidden moisture or rot
- Properly repaired – any damaged sections patched before siding is installed
Most contractors install vertical furring strips through the stucco into the wall framing. This creates a flat base, adds ventilation, and allows water to drain, preventing mold and rot.
If the stucco is severely damaged or moisture-logged, it may need to be removed before siding can be installed.
Popular Siding Options to Install Over Stucco
When replacing stucco with siding, New Jersey homeowners typically choose from these materials:
1. Vinyl Siding
- Budget-friendly and low-maintenance
- Available in many colors and textures
- Moisture-resistant, ideal for NJ’s humid summers and snowy winters
- Can be paired with insulated panels for better energy savings
Can you install vinyl siding over stucco? Yes, with furring strips, a moisture barrier, and optional foam insulation.
2. Fiber Cement (James Hardie)
- Durable, pest-resistant, and fire-resistant
- Mimics the look of wood in lap, shingle, or panel styles
- Performs well in NJ’s freeze-thaw cycles and coastal storms
- Heavier and more expensive than vinyl, but longer-lasting
Can you put Hardie board over stucco? Yes, as long as the stucco is stable and installation follows James Hardie’s guidelines.
3. Board and Batten
- A style rather than a specific material
- Often created using fiber cement or engineered wood panels with vertical battens
- Adds a modern farmhouse or rustic look
- Works well as an accent wall or full-home style
Can you put board and batten over stucco? Absolutely, with proper prep and moisture control.
4. Engineered Wood or Metal Siding
- Engineered wood offers a natural look with better weather resistance than traditional wood
- Metal siding (steel or aluminum) stands up to wind and salt air but can dent
- Less common over stucco, but possible with the same installation process
How to Install Siding Over Stucco
Here’s what a typical New Jersey siding-over-stucco installation looks like:
- Inspect and Repair Stucco
Seal cracks under ¼ inch and patch larger damage. Replace any rotted sheathing before proceeding. - Add a Moisture Barrier
Install a weather-resistant barrier (WRB) such as house wrap or asphalt felt over the stucco to prevent trapped moisture. - Attach Furring Strips
Vertical wood strips are fastened through the stucco into wall studs, spaced about 16 inches apart. - Install Insulation (Optional)
Rigid foam boards between the furring strips improve energy efficiency – a big benefit in NJ winters. - Install Siding
Fasten vinyl, fiber cement, or board-and-batten panels to the furring strips, using proper flashing and trim. - Finish Trim and Soffits
Replace or update trim, soffits, and fascia to match the new siding thickness.
Moisture and Insulation Concerns
Stucco is porous, meaning it can absorb and hold water. Without an air gap, water may get trapped behind new siding.
To prevent this:
- Always use furring strips to create ventilation
- Install a breathable WRB
- Seal all window and door openings with flashing
- Add insulation during installation to improve comfort and reduce heating/cooling costs
New Jersey Climate Considerations
Freezing Winters and Thaw Cycles
In winter, surfaces freeze and expand, then thaw and contract. Continuous freeze-thaw can lead to siding cracks or warping if materials aren’t rated for these cycles. Vinyl siding with flexible locking systems or fiber cement (James Hardie) rated for harsh cold performs better long-term.
Humid Summers and Rainfall
High humidity and frequent summer storms saturate exterior walls. A ventilated substrate and water-resistant barrier become critical to keep moisture out of the framing. Plus, of the siding materials, both vinyl and fiber cement resist rot and mildew far better than real wood in damp conditions.
Coastal Storms and Wind
Homes near the Jersey Shore face intense nor’easters and ocean winds. You’ll want impact-resistant siding or reinforced fastening systems-especially with thicker materials like fiber cement. Soffits and fascia should be securely attached to handle high wind loads.
Hot Temperatures and Heat Expansion
Hot summer temperatures and intense sun can cause materials to expand. Lighter color siding helps, but it’s also important to leave small gaps at seams for thermal expansion. Coupled with proper nailing and clips, your siding can survive long-term in NJ’s fluctuating temperatures.
Pros and Cons
Benefits (Pros)
- Eye-Catching Curb Appeal: Siding instantly transforms the look of a home, hides blemishes, and comes in diverse styles-clapboard, board-and-batten, shakes-even bold colors.
- Lower Upkeep: Unlike stucco, which may crack or need repainting, materials like vinyl or fiber cement hold up longer with minimal maintenance.
- Improved Weather Defense: Proper installation adds a secondary shield against wind-driven rain-a big plus in NJ’s coastal and storm-prone areas.
- Energy Efficiency Gains: With added foam or insulated siding, you’ll retain heat in winter and keep cool in summer, lowering HVAC usage. Over time, these savings can offset the cost of the siding project.
Drawbacks (Cons)
- Moisture Hazards: If you skip ventilation or WRB, you risk trapping water-leading to rot, mold, and structural damage.
- Higher Cost vs Painting: Painting stucco is always cheaper upfront than a full siding replacement, but that can be a short-term fix.
- Possible Hidden Damage: Covering stucco can disguise underlying issues like rot or poor framing. If these exist, they can worsen beneath the siding.
- Altered Home Character: Some homeowners love the classic look of stucco. Once you cover it, it’s not coming back-especially with styles like board-and-batten, which contrast sharply with stucco.
- Trim and Flashing Adjustments: Adding layers means windows and doors may sit deeper. You’ll need additional trim or flashing to ensure a clean fit and proper sealing.
Common Mistakes to Avoid
1. Skipping Stucco Repair
Never cover over cracked, wet, or loose stucco. Seal minor cracks and professionally patch major damage. If stucco is unstable, demolition might be safer to avoid future rot.
2. Avoiding Furring Strips and Air Gaps
Trying to install siding directly on stucco without strips kills ventilation and leads to trapped moisture and eventually, mold or rot. Always include strips and leave an air gap.
3. No Moisture Barrier
A WRB is your insurance against water infiltration. Skipping it may result in hidden water damage that surfaces only after your siding fails.
4. Missing the Insulation Opportunity
Don’t miss the chance to upgrade energy efficiency. Even a half-inch of rigid foam under your siding helps keep your home warmer in winter and cooler in summer.
5. Neglecting Local Permit Needs
Many NJ towns require permits for siding replacement, even if you’re just covering existing materials. Permits can range from $200 to $500. Always check local building codes first.
6. Choosing Inexperienced Installers
Stucco-to-siding conversions require skill in flashing, sealing, and proper fastening. Many manufacturers (like James Hardie) will void warranties if done incorrectly. Hire installers with a solid track record in this specific process.
7. Overlooking Window and Door Edges
Adding foam and furring changes wall depth. If not properly anticipated, windows can sink in, creating gaps. Cap or extend window trim to keep things flush and secure.
8. Skipping Aftercare Maintenance
Even low-maintenance siding benefits from occasional cleaning and inspection-especially around vents, lights, or gaps-to prevent small issues from becoming big problems.
FAQs
1. Can you put siding directly over stucco?
Yes, in many cases, siding can be installed directly over stucco as long as the stucco is in good condition. However, any cracks, moisture damage, or structural issues must be repaired first. A furring strip system or moisture barrier is often added for better results.
2. Do you need to remove stucco before adding siding?
Not always. If the stucco is stable and not crumbling, you can install siding over it. But if there are major cracks, mold, or water damage, removal may be necessary to prevent future problems.
3. What type of siding works best over stucco?
Popular options include vinyl siding, fiber cement siding like James Hardie, and durable engineered wood siding. These materials are durable, weather-resistant, and can be installed over a prepared stucco surface.
4. Will siding over stucco cause moisture problems?
If installed correctly with a proper moisture barrier, siding over stucco should not cause moisture problems. However, poor installation can trap moisture between layers, leading to rot or mold.
5. Does installing siding over stucco improve insulation?
Installing new siding, particularly when combined with insulated underlayment, can enhance your home’s thermal performance. This added layer helps maintain consistent indoor temperatures, which may lead to reduced energy expenses.
6. Is siding over stucco expensive?
Costs vary based on the type of siding, labor rates, and whether the stucco needs repairs. Generally, installing siding over existing stucco is more affordable than completely removing the stucco first.
7. How long will siding over stucco last?
Properly installed, premium-quality siding can often serve your home for 20 to 40 years or even longer with the right care. Durability depends on the siding material, climate, and how well the installation addresses moisture and insulation concerns.
8. Can I DIY siding installation over stucco?
It’s possible for skilled DIYers, but siding installation over stucco can be tricky due to moisture barriers, fastening requirements, and surface leveling. Professional installation is recommended for best results.
