Some garage conversion projects may not require the removal of garage doors. If so, you need to take note of certain elements to ensure this project completes with as minimal errors and issues as possible.

Plans

Like any other home remodeling project, enclosing a garage requires you to follow a well-thought plan of action. Have the necessary documents, such as blueprints and permits, to ensure this operation goes as smoothly as possible.

Also, keep in mind that ‘winging it’ isn’t an option for this case. Otherwise, you’ll most likely commit to expensive mistakes.

Costs

Homeowners should prepare to spend about $5,732 to $23,993 to convert their garages. The project's demands will dictate the costs of this investment. For instance, the overhead may skyrocket if you need to install additional fixtures for electricity, heating, and plumbing.

Other factors that can affect the expected costs are:

  • Insulation
  • Furnishing
  • Waterproofing
  • Access point creation
  • Professional labor

Clean and Declutter

It can be relatively easier to enclose a garage if junk isn't all over the space. You can clean and declutter the area by yourself. But if you don't have the time to do this extra task, you can consult the help of professional junk removal services. If so, prepare to spend an extra $100 to $800, depending on the amount of trash to dispose of.

Insulation

Enclosing and converting the garage into a living space should also mean that the space needs to be reasonably comfortable. Insulating the new room can help prevent comfort and structural issues, particularly during the winter.

Take note that you have different types of insulation to choose from for this part of the renovation project, including:

  • Fiberglass: A reasonably inexpensive choice but can become a fire hazard if installed improperly.
  • Rigid foam: Often possess a relatively high R-value, making it a good choice for properties in fairly cold locales.
  • Spray foam: Creates an airtight seal but may shrink over time.
  • Cellulose: Quite expensive but known to have high resistance against pests and high temperatures.

Garage Door

Since you decided that you’re going to keep the garage door, you may want to think about repurposing it. If so, you can choose to:

  • Seal the door.
  • Dress the garage door with treatments.
  • Build a wall over the door for extra security and insulation.

Otherwise, you can remove the garage door and replace it with another type of opening, such as a French door. However, replacing the garage door is going to be a separate DIY operation, which may demand additional requirements.
