Siding is an essential component of any home’s exterior, offering protection from the elements and enhancing the overall aesthetics of the property. Over time, homeowners may consider updating or replacing their existing siding to improve curb appeal or address any damage. One common question that arises during this process is whether lap siding can be installed over existing siding. In this article, we will explore this topic in detail and provide you with the information you need to make an informed decision.
Understanding Lap Siding
Lap siding, also known as horizontal siding, is a popular choice among homeowners for its timeless appeal and durability. It comprises long, narrow boards that overlap each other, creating a waterproof seal and a visually pleasing appearance. Lap siding is available in various materials, including wood, vinyl, fiber cement, and aluminum, providing homeowners with a wide range of options to suit their preferences and budget.
Examining the feasibility of installing lap siding over existing siding
Before starting any siding project, it is crucial to assess the current condition of the exterior walls and the existing siding. Installing lap siding over existing siding may be a viable option in some cases, but it depends on several factors.
1. Assessing the condition and type of existing siding
Evaluate the condition of the existing siding to determine if it is suitable to serve as a base for the new lap siding. If the existing siding is in good condition, free from rot, decay, or major damage, installing lap siding over it may be an option. However, it is essential to identify the type of siding currently in place, as this can impact the installation process.
2. Compatibility of materials and thickness
When considering lap siding installation over existing siding, it is crucial to ensure compatibility between the two materials. The new lap siding should bond well with the existing siding, ensuring a seamless and durable application. Additionally, the thickness of the combined layers should be within the structural tolerances specified by building codes.
3. Surface preparation
Proper surface preparation is key to a successful installation. The existing siding should be thoroughly cleaned, free from dirt, debris, and loose paint. It may be necessary to pressure wash or scrape off any peeling paint or contaminants. Moreover, ensure that any protruding nails or loose boards are addressed before proceeding with the installation.
Benefits and drawbacks of installing lap siding over existing siding
There are advantages and disadvantages to installing lap siding over existing siding, which should be carefully considered before making a decision.
Benefits:
- Cost-saving: Installing lap siding over existing siding can be more cost-effective than completely removing the existing siding and installing new sheets or panels.
- Time-saving: The installation process may be quicker since there is no need for extensive removal or demolition.
- Added insulation: The added layer of lap siding can provide an additional thermal barrier, enhancing the energy efficiency of the property.
Drawbacks:
- Visual appearance: Depending on the material, texture, or color of the existing siding, some homeowners may find that installing lap siding over it does not achieve the desired aesthetic result, compromising curb appeal.
- Potential for hidden damage: If the existing siding has concealed damage or issues, such as rot or mold, covering it up with new lap siding without addressing these issues may worsen the problem in the long run.
- Limited lifespan: The overall durability and lifespan of the lap siding may be affected if installed over a compromised base. It is essential to ensure the existing siding provides a stable and secure foundation.
Final considerations and professional guidance
Considering the complexity of installing lap siding over existing siding, seeking professional advice and assistance is highly recommended. A siding contractor can assess your specific situation, evaluate the condition of your existing siding, and provide guidance on whether this installation method is suitable for your home.
In summary, installing lap siding over existing siding can be a feasible option, but careful evaluation is required. As with any home improvement project, a comprehensive assessment of the existing materials, surface preparation, compatibility, and long-term considerations is essential. Consulting with professionals ensures a successful outcome, offering both visual appeal and long-lasting durability.
