This article aims to explore whether it’s possible to install new siding over existing siding, delving into the pros and cons of this approach.
Understanding the Existing Siding:
Before deciding on whether to install new siding over existing siding, it is crucial to assess the condition of the current siding. If the existing siding is severely damaged, rotting, or has moisture issues, it is wise to have it removed and replaced entirely before installing new siding. Installing over damaged siding can exacerbate existing issues and compromise the longevity and performance of the new siding.
Advantages of Installing Over Existing Siding:
1. Time and Cost Savings:
One of the key benefits of installing new siding over existing siding is the potential time and cost savings. Removing old siding can be a labor-intensive and time-consuming process. By installing new siding over the existing one, you eliminate the need for this step, reducing both the time and cost involved in the installation process.
2. Increased Insulation:
The additional layer of siding can improve insulation properties, providing an extra barrier against heat loss and thermal bridging. This can contribute to enhanced energy efficiency and potentially lower heating and cooling costs.
3. Enhanced Protection:
Installing new siding over the existing siding offers an extra layer of protection to your home’s exterior. It provides an additional shield against moisture, pests, UV rays, and other damaging elements.
Disadvantages of Installing Over Existing Siding:
1. Reduced Aesthetic Appeal:
Adding an extra layer of siding can result in an increased thickness, which may alter the dimensions and proportions of your home’s exterior. This can be visually unappealing and may not achieve the desired aesthetic outcome.
2. Potential Structural Issues:
Installing new siding over existing siding can hide underlying structural issues, such as rotting or deteriorating sheathing. If these problems go unnoticed, they can lead to more significant and costly repairs down the road.
3. Limited Lifespan:
By installing new siding over the existing siding, you aren’t addressing any potential issues beneath the surface. The old siding may continue to deteriorate, potentially reducing the overall lifespan of the new siding as well.
Considerations before Installing Over Existing Siding:
1. Building Codes and Regulations:
Before proceeding with installing new siding over existing siding, ensure that it complies with local building codes and regulations. Some areas may have specific requirements regarding the number of layers of siding allowed.
2. Thickness and Compatibility:
Consider the added thickness of the new siding and how it will affect windows, doors, and other exterior elements. Additionally, ensure that the new siding is compatible with the existing siding material for proper installation and aesthetics.
3. Professional Consultation:
It is always advisable to consult a professional siding contractor to evaluate the condition of the existing siding and determine the best course of action. They can provide expert advice based on your specific situation and help you make an informed decision.
While it is technically possible to install new siding over existing siding, it is crucial to assess the condition of the current siding and weigh the advantages and disadvantages. Taking into account factors such as aesthetics, structural integrity, and local regulations will help you determine the most suitable approach for your home. Consulting with a professional siding contractor can further guide you in making an informed decision that ensures the longevity and performance of your new siding installation.
