Why May You Want to Replace Rotted Wood Siding?

1. To Protect Your Home From Further Water Damage

One of the main reasons to replace your rotted wood siding is to prevent further water damage from occurring. If the wood has already begun to rot, chances are that more water and moisture may have seeped into other areas of the house as well. Replacing the rotted section will help keep your home safe from additional water damage.

2. To Improve Energy Efficiency

Another great reason to replace rotted wood siding is to improve your home’s energy efficiency.

By replacing the rotted wood with new, energy-efficient materials, you can help reduce your monthly heating and cooling costs while keeping your home comfortable all year round.

3. To Enhance Your Home’s Curb Appeal

Finally, replacing rotted wood siding can help to boost your home’s curb appeal. If your home is looking a bit worn and outdated, adding a new section of siding can instantly give it an updated look. Plus, taking the time to replace the rotted section now will help you avoid having to replace an even larger section later on, which can save you time and money in the long run.

Even if replacing the old wood siding is too costly, do not cover up the problem with new wood. This will just cause further damage to your home and eventually can lead to a large-scale repair project.

Be sure to inspect your siding regularly for signs of rot or water damage. Make sure to check around windows and doorways where rot is more likely to occur.

When replacing your wood siding, it’s important to use the proper materials for the job. Using pressure-treated lumber or other moisture-resistant products can help protect against future rotting or water damage.

4. Seal Gaps & Cracks

Gaps and cracks can easily form in wood siding over time, so it’s important to make sure that you seal them properly. Use caulk or high-quality sealants to fill these gaps and ensure a tight fit and long-lasting protection.
