DIY Fireplace Transformation: Upgrade Your Space with Scrap Wood
Introduction
This blog post will walk you through my latest DIY woodworking project: transforming the fireplace using only scrap wood. Not only did I accomplish this with zero extra spending, but I also achieved a cohesive look that ties into the rest of my home decor. Let’s dive into the details of this DIY Fireplace Transformation!


The Challenge: Zero Dollars Spent
We’re getting a new Samsung TV above the fireplace, and I wanted to upgrade this space without spending any money. So, I challenged myself to use only materials from my garage scrap pile. This project proves that hoarding scrap wood can be incredibly beneficial for spontaneous DIY projects!
The Plan: Shiplap to Basic Box
Initially, I planned to use shiplap above the mantle but quickly realized I didn’t have enough material. I had to pivot to a new plan, which I call the “Basic Box.” It mimics the square design in my living room photo wall (see below picture) and also the trim pieces I used for my asymmetrical wall project.

Materials and Tools
- Scrap wood (from the garage scrap pile)
- MDF (Medium-Density Fiberboard)
- Vinyl Stop Molding
- Bondo (for seams)
- Mask (for safety while using Bondo)
- Saw (for 45-degree cuts)
- Cordless sander (for smoothing Bondo)
Step-by-Step Tutorial
1. Planning and Measuring
First, I assessed the available scrap wood and made a cut list to use the wood more efficiently. This step is crucial to ensure you don’t run out of materials midway through the project (hence the pivot from the shiplap idea).
2. Cutting the Wood
I made all 45-degree cuts for the scraps. For the MDF, I cut an exact square detail for the frame corners.

3. Assembling the Frame
With all pieces cut, I began assembling the frame around the fireplace. The square design not only looks stylish but also complements existing decor without introducing new trim styles.

4. Sealing the Seams
I used Bondo for the seams, which is perfect for achieving a smooth, seamless look. Bondo dries super fast and hard, making it an excellent choice for molding. Remember, it has a strong odor, so wearing a mask is necessary…

5. Sanding and Finishing
After allowing the Bondo to dry for 30 minutes, I sanded it down to create a smooth finish. This step is crucial for ensuring the frame looks like one big piece, rather than several smaller pieces assembled together. With a little bit of paint (Color: Benjamin Moore Amherst Gray), this project really came together!

Final Thoughts
Although we’re preparing to sell this house, I think this DIY fireplace transformation not only ties in to the design of the rest of my home but also demonstrated the value of utilizing scrap materials. The “Basic Box” frame around the fireplace adds a touch of elegance and cohesiveness to our home decor without breaking the bank!
