Vinyl Siding Over Wood Siding A Complete Guide

Vinyl siding over wood siding: It sounds simple, right? But covering your existing wood siding with vinyl involves more than just slapping up some new panels. This guide dives into the costs, the process, the pros and cons, and even the potential pitfalls to help you decide if this is the right choice for your home. Finally, we’ll explore the aesthetic considerations and the environmental impact of each option, giving you the complete picture to make an informed decision.

Cost Comparison

Choosing between vinyl and wood siding involves a significant financial commitment. Understanding the costs associated with materials, labor, and long-term maintenance is crucial for making an informed decision. This section breaks down the expenses involved over a typical 20-year lifespan.

Material Costs

Vinyl siding is generally less expensive than wood siding upfront. The price of vinyl varies depending on the quality, style, and color, but you can typically expect to pay between $3 and $15 per square foot. Wood siding, on the other hand, ranges from $10 to $40 or more per square foot, with the price increasing significantly for higher-grade woods like cedar or redwood. This difference is largely due to the manufacturing processes and the inherent value of natural wood. For example, a 1000 square foot house might see a material cost difference of several thousand dollars between vinyl and a premium wood siding option.

Labor Costs

Labor costs are another area where differences emerge. While the installation process for vinyl siding is generally faster and simpler, requiring less specialized skill, the cost per square foot isn’t drastically different. Expect to pay roughly $2 to $5 per square foot for vinyl siding installation and $3 to $8 per square foot for wood siding installation. The higher end of the wood siding labor cost reflects the increased complexity of installation, potentially including extra work for trim and detailed finishing. The actual labor cost will also depend on factors such as geographic location and the contractor’s experience.

Long-Term Maintenance Costs

This is where the biggest difference lies. Vinyl siding requires minimal maintenance. Occasional cleaning with a hose and mild detergent is usually sufficient. Wood siding, however, requires regular maintenance, including repainting or restaining every few years, which can be a significant ongoing expense. Repairing damaged wood siding is also more expensive and labor-intensive than repairing vinyl siding. For instance, replacing a damaged wood plank might require specialized carpentry skills and more costly materials, unlike a simple vinyl panel replacement.

Installation Process

Installing vinyl siding over existing wood siding is a relatively straightforward process, but proper preparation and technique are crucial for a long-lasting, attractive finish. This involves several steps, from preparing the existing wood siding to carefully installing the vinyl panels and flashing around windows and doors. Let’s break down the process.

Tools and Equipment

Before you begin, gather the necessary tools and equipment. This will ensure a smooth and efficient installation. You’ll need a measuring tape, level, chalk line, utility knife, circular saw (or hand saw), hammer, drill, screwdriver bits (Phillips and flathead), safety glasses, work gloves, and a ladder. Specific tools for cutting vinyl siding, like a vinyl siding cutter or a sharp utility knife with a scoring blade, will make the job easier and cleaner. You’ll also need the vinyl siding itself, starter strips, J-channel, finishing pieces, and appropriate fasteners. Don’t forget caulk and sealant for weatherproofing.

Preparing the Wood Siding

Proper preparation of the existing wood siding is essential for a successful vinyl siding installation. Begin by inspecting the wood siding for any loose boards, rot, or damage. Replace or repair any damaged areas. Loose boards should be securely nailed or screwed back in place. Rotted wood needs to be cut out and replaced with new lumber. Next, thoroughly clean the wood siding to remove dirt, debris, and loose paint. A pressure washer can be very helpful for this step, but be careful not to damage the wood. Once clean and dry, it’s crucial to address any significant gaps or unevenness in the wood siding surface. Using wood filler, you can fill in small gaps and imperfections, ensuring a smooth, level surface for the vinyl siding.

Flashing and Sealing Around Windows and Doors

Proper flashing and sealing are critical for preventing water damage. Before installing vinyl siding around windows and doors, install flashing to redirect water away from these vulnerable areas. Flashing typically consists of metal or plastic strips that are installed under the vinyl siding to create a waterproof barrier. The flashing should overlap appropriately to prevent water penetration. After the flashing is in place, carefully install the vinyl J-channel around the window or door frames. This channel provides a neat finish and helps protect the edges of the siding. Use high-quality exterior-grade caulk or sealant to seal any gaps between the flashing, J-channel, and the window or door frames. Pay close attention to all corners and seams to ensure a completely watertight seal.

Step-by-Step Visual Guide

Imagine the house’s exterior wall. First, install a starting strip along the bottom edge of the wall, creating a level base for the first row of siding. This strip ensures a straight, even start for your vinyl siding.

Next, install the first row of vinyl siding, engaging the bottom edge into the starter strip. Each panel should overlap the previous one, typically with a small amount of overlap specified by the manufacturer’s instructions. Use appropriate nails or screws to fasten the panels securely, making sure to avoid overdriving the fasteners which can damage the siding.

Continue installing rows of vinyl siding, ensuring each panel is level and properly overlapped. As you approach windows and doors, install the J-channel and flashing as described previously.

For corners, use corner trim pieces. These pieces provide a clean, finished look at the exterior corners of the building. They are designed to overlap the vinyl siding and guide the installation of panels around the corner.

Finally, install the finishing pieces, such as the soffit and fascia, to complete the installation. These pieces provide a professional, finished look and protect the edges of the siding from the elements. Remember to always refer to the manufacturer’s instructions for specific details and recommendations.

Long-Term Durability and Maintenance: Vinyl Siding Over Wood Siding

Installing vinyl siding over wood siding can significantly extend the life of your home’s exterior, but understanding the long-term implications is crucial. This section details the expected lifespan, maintenance needs, potential problems, and the critical role of ventilation in ensuring the longevity of both the vinyl and the underlying wood.

Vinyl siding, when properly installed, boasts a remarkable lifespan. While manufacturers often quote lifespans ranging from 20 to 50 years, the actual longevity depends heavily on several factors including the quality of the vinyl, the installation process, and the environmental conditions. Proper ventilation plays a key role, preventing moisture buildup which is a major contributor to premature deterioration of both the vinyl and the wood beneath. Considering the initial investment and the added layer of protection, a well-installed vinyl siding system should offer a substantial return in terms of extended building life and reduced maintenance compared to maintaining bare wood siding.

Vinyl Siding Lifespan and Maintenance Compared to Wood

Vinyl siding generally requires far less maintenance than wood siding. Wood siding needs regular painting or staining to prevent rot, insect infestation, and weathering. It may also require occasional repairs due to damage from impacts or decay. Vinyl, on the other hand, is resistant to rot, insects, and most types of weathering. Cleaning usually involves simply washing it down with a garden hose or using a mild detergent solution for stubborn dirt. While vinyl can be scratched or dented, these issues are typically cosmetic and don’t compromise the structural integrity. A well-maintained vinyl siding system could easily outlast several repainting cycles for a wood siding system, resulting in significant long-term cost savings. For example, a home with wood siding might require repainting every 5-7 years, at a considerable cost, whereas vinyl siding might only require occasional cleaning over the same period.

Common Issues and Solutions

Despite its durability, vinyl siding over wood can encounter problems. One common issue is moisture accumulation beneath the vinyl. This can lead to mold, mildew growth, and rot of the underlying wood siding. Proper ventilation, as discussed later, is crucial to prevent this. Another issue is damage from impacts, such as hail or falling branches. While vinyl is relatively impact-resistant, severe impacts can cause dents or cracks. Repairing these usually involves replacing the damaged section of siding, a relatively straightforward process compared to repairing damaged wood siding. Finally, improper installation can lead to problems like gaps or loose panels, allowing water penetration. Addressing these issues promptly is important to prevent more extensive damage. A professional inspection during installation and periodic checks thereafter can help identify and address these issues early on.

Ventilation’s Impact on Longevity, Vinyl siding over wood siding

Adequate ventilation is paramount for the long-term health of both the vinyl and the wood siding underneath. Without proper ventilation, moisture trapped between the vinyl and the wood creates an ideal environment for mold, mildew, and rot. This can lead to premature failure of both materials, significantly shortening the lifespan of the entire siding system. Proper ventilation should be designed and implemented during the initial installation. This often involves ensuring sufficient gaps and air circulation behind the vinyl siding, potentially through the use of vented soffits and ridge vents. Regular inspection of the ventilation system can help to identify any blockages that might compromise its effectiveness. Failing to address ventilation issues can lead to costly repairs and significantly reduce the lifespan of the entire siding system, negating the benefits of choosing vinyl over wood. For instance, a home with insufficient ventilation might experience premature wood rot within 10 years, while a well-ventilated home with the same siding could easily last for 30 years or more.
