When it comes to home improvement projects, choosing the right type of siding is crucial in not only enhancing the overall appearance of your home but also in protecting it from the elements. Cement siding has gained popularity in recent years due to its durability, low maintenance, and resistance to rot and pests. However, if you already have wooden siding installed on your home, you may be wondering if it’s possible to mount cement siding over it. In this article, we will explore whether cement siding can indeed be mounted over wooden siding and discuss the factors to consider when making this decision.
Understanding Cement Siding:
Cement siding, also known as fiber cement siding, is a composite material made from a mix of Portland cement, sand, and cellulose fibers. This combination creates a durable and fire-resistant material that mimics the look of wood or other natural materials. Cement siding is well-known for its longevity, with manufacturers often offering warranties of up to 50 years. It is available in various styles, colors, and textures, making it a versatile choice for homeowners.
Factors to Consider:
Before deciding to mount cement siding over existing wooden siding, there are several factors to consider:
1. Condition of the Wood:
The first step is to assess the condition of your existing wooden siding. Cement siding should never be mounted over rotten or damaged wood. Any issues with the wood should be addressed and repaired before proceeding with the installation of cement siding.
2. Moisture Concerns:
Wooden siding allows for some degree of breathability, which helps to dissipate moisture and prevent build-up. Cement siding, on the other hand, is non-breathable. If moisture becomes trapped between the two layers, it can lead to rot or other issues. Proper moisture management systems, such as the installation of a vapor barrier, should be put in place to prevent potential moisture-related problems.
3. Additional Weight:
Cement siding is heavier than wooden siding. Before mounting cement siding over wooden siding, it is essential to ensure that the structural integrity of your home can support the additional weight. Consulting with a structural engineer or a professional contractor can help determine if any modifications are necessary.
4. Windows, Doors, and Trim:
Mounting cement siding over wooden siding may affect the depth around windows, doors, and trim, potentially leading to visual inconsistencies. Ensure that any alterations required will maintain a cohesive appearance throughout your home’s exterior.
Installation Process:
If you have thoroughly considered all the factors mentioned above and have decided to proceed with mounting cement siding over your wooden siding, the following is a general outline of the installation process:
1. Preparation:
Prepare the existing wooden siding by thoroughly cleaning it of any dirt, grime, or loose paint. Repair any damaged areas, and ensure a smooth, stable surface.
2. Installation of Moisture Management Systems:
Install any necessary moisture management systems, such as a vapor barrier, to prevent moisture-related issues between the two layers of siding.
3. Furring Strips:
Attach furring strips over the wooden siding for improved stability. These strips create a flat surface for the cement siding to be installed.
4. Cement Siding Installation:
Follow the installation guidelines provided by the manufacturer for proper installation of cement siding. This typically involves nailing or screwing the cement siding into the furring strips, ensuring appropriate overlap and alignment. Use the proper tools and techniques for cutting and shaping the siding as needed.
While cement siding can indeed be mounted over wooden siding, several important factors need to be considered before proceeding with the installation. Assessing the condition of the existing wooden siding, addressing moisture concerns, ensuring the structural integrity of your home, and considering the impact on windows, doors, and trim are crucial steps in making an informed decision. By carefully examining these factors and following the proper installation guidelines, you can enjoy the benefits of cement siding while enhancing the aesthetic and durability of your home.
