Step-by-Step Garage Renovation: Planning & Demo
September 10, 2025

For many homeowners, the garage serves as a multipurpose space, often doubling as a workshop, storage area, or even a catch-all for items that don’t fit elsewhere. However, neglected and cluttered garages can quickly become a source of frustration. In this in-depth guide, inspired by a hands-on renovation project, we’ll explore the transformative process of turning a chaotic garage into an efficient, organized, and aesthetically appealing space.
Whether you’re in North Idaho or Eastern Washington, revitalizing your garage can enhance not only your home’s functionality but also its value. Let’s dive into the step-by-step journey of planning, demolition, and early renovation, offering practical tips and insights to help you tackle your own garage makeover.
Planning Your Garage Renovation: Start with a Vision
The first step in any successful renovation is a clear vision for the space. In this project, the homeowner’s goal was to create a clean, organized workshop where tools and equipment could be neatly stored out of sight. Here’s how they structured their planning phase:
1. Identify Problem Areas
The homeowner expressed frustration about the clutter and inefficiency of their garage, which was being used for temporary storage, unfinished projects, and mismatched tools. Key problem areas included:
- Outdated pegboards that were disorganized and aesthetically unappealing.
- A workbench crowded with tools and scrap material.
- A lack of proper storage for lawn equipment, such as a lawn mower and hedge trimmer.
By taking inventory of inefficiencies, they were able to focus on solutions that would maximize the garage’s functionality.
2. Create a Functional Layout
The homeowner envisioned designated zones for specific needs:
- Cabinetry for hidden storage to keep tools and materials out of sight.
- A dedicated workstation for the computer and monitors, complete with proper wiring for HDMI and Ethernet connections.
- Storage for lawn equipment in custom-built cabinets.
- A pressure washer and vacuum station for added convenience.
The layout also accounted for future upgrades, such as improved lighting and a utility sink.
3. Plan for Durability and Efficiency
When selecting materials, the renovation prioritized durability and ease of cleaning. Rockwool insulation was chosen for its soundproofing and thermal properties, while the placement of electrical outlets and data cables ensured the space would be future-proof.
Demolition: Clearing the Path to Transformation
Once the plan was in place, the renovation moved into the demolition phase. This step can be labor-intensive but is essential for achieving a fresh start. Here’s how to tackle demolition safely and efficiently:
1. Clear the Space
Before removing drywall or starting construction, all items were removed from the garage. Temporary storage solutions were used to keep the clutter out of the way, allowing for an open, workable area.
2. Remove Old Fixtures
The homeowner demoed the existing drywall and insulation, uncovering the structure and framing beneath. This step revealed areas that already had insulation in place, such as the front door wall, and allowed for decisions on whether to retain or replace certain materials.
3. Dispose of Waste
Efficient waste disposal was a priority. The homeowner loaded up the truck with removed drywall and other debris, making early morning trips to the dump to keep the workspace clean and manageable.
Demolition can reveal surprises, such as unexpected framing configurations or insulation. Assess these discoveries as opportunities to refine your plan as circumstances evolve.
Laying the Foundation: Insulation, Electrical, and Plumbing
With the space cleared, the renovation shifted to building the foundation for a functional and polished garage. Here’s what the process looked like:
1. Insulation Installation
Rockwool insulation was selected for its superior soundproofing and thermal performance. Cutting and fitting the insulation took careful attention to detail, with adjustments made for tight spaces and irregular framing.
2. Electrical and Wiring
The homeowner installed electrical outlets within the planned cabinetry to power cabinet lighting, monitors, and a mini fridge. Additionally, they ran a home run (a direct electrical line) from the subpanel to dedicated outlets for high-powered tools such as a pressure washer.
Pro Tip: Future-proof your space by running Cat 6 cables for Ethernet connectivity, ensuring reliable internet access for computers or smart devices.
3. Plumbing for a Utility Sink
Recognizing the value of a sink in a workshop, the homeowner added hot and cold water lines using PEX piping. This small addition significantly enhances the functionality of the space, making it easier to clean tools and rinse hands after projects.
Drywall and Primer: Bringing It All Together
With the wiring and insulation completed, it was time to install drywall and prepare the walls for painting. This step marked a visible transformation in the space:
- Precision in Drywall Installation: The homeowner carefully installed sheetrock, paying attention to areas near plumbing and electrical fixtures. After mudding and sanding, the walls were ready for primer.
- Primer Application: Applying primer was a crucial step to prepare the walls for a smooth, durable finish. Although time-consuming, this stage laid the groundwork for the final coat of paint.
Key Takeaways: Practical Insights for Your Garage Renovation
