How to Demo and Remove Two Chimneys – YouTube
Materials Needed
- Pry bars
- Long and short rods
- Sledgehammers
- Hammers
- Air gun nailer
- Metal flashing
- T1-11 siding panels
- Caulking
- Waterproofing material
- Roofing shingles (matching existing roof)
- Drop cloths
- Ladder
- Paintbrush and roller (for painting the siding)
Step-by-Step Process
1. Start with the Trim Removal
The project began by removing the trim and siding around the left chimney. Using pry bars and hammers, carefully remove each panel and nail without rushing. Taking your time ensures that the workspace remains clean and the panels come off without causing excessive damage.
2. Expose the Chimney Structure
Once the trim and siding are removed, the chimney structure is revealed. The first chimney contained a metal tubing inside, which directed the smoke and heat from the fireplace. This tubing was removed, exposing the wooden framing, insulation, and exterior panels. The second chimney, being taller and harder to access, required extra caution but followed a similar removal process.
3. Begin Demolition from the Top
With both chimneys exposed, the demolition began at the top and worked downward. Using sledgehammers and pry bars, the framing (made up of 2x4s or 2x6s) was carefully removed along with the exterior siding. During this process, ensure that any debris is safely contained, especially if working in tight spaces near fences or neighboring properties.
4. Install New Metal Flashing
After the chimney is removed, it’s crucial to install metal flashing in the areas where the chimney once stood. This flashing helps prevent water from penetrating the new siding and redirects rain away from the structure. Measure and cut the flashing carefully to fit around existing sections of the house.
5. Install New Siding
Next, install the new T1-11 siding panels to match the existing siding of the house. Use an air gun nailer to secure the panels, ensuring that they are level and properly aligned. Make sure to leave a small gap for the flashing, allowing water to flow out properly and not collect inside the walls.
6. Seal the Area with Caulking
To ensure a waterproof seal, apply caulking along all the joints and seams where the new siding meets the old. Focus on areas where water could potentially seep in, such as where the siding meets the flashing or roofline.
7. Paint the New Siding
Finally, apply a high-quality exterior paint to the newly installed siding. Start by painting the seams and joints with a brush, then use a roller for the larger surfaces. Applying multiple layers of paint not only ensures a professional finish but also protects the siding from weather damage.
Pro Tips
- Take it slow: Chimney removal is a detailed process, and rushing can lead to damage. Removing one panel at a time ensures a clean demolition.
- Debris management: Be mindful of debris, especially if working in tight spaces between houses. A clean site is a safer and more efficient work environment.
- Waterproofing is key: Pay special attention to sealing the area with metal flashing and caulking to prevent future leaks.
- Use quality materials: High-quality siding, flashing, and paint will ensure long-lasting results and protect the structure from weather damage.
