Cost to Insulate Garage Walls
Insulating garage walls involves filling cracks and gaps, fitting insulation between the studs, and covering the walls with drywall to improve thermal efficiency. It is a moderate-difficulty job: cutting insulation to fit and taping and mudding drywall joints are parts to weigh before deciding whether to tackle it yourself.
Common reasons homeowners do this job
- Improving the garage's thermal efficiency
- Adding insulation to garage walls that lack it
- Upgrading the garage walls as part of a broader improvement
- Addressing wall cracks and gaps as part of insulation work
DIY or call a pro?
Consider a professional if you are unsure how the wall construction affects insulation choice or are uncomfortable fitting insulation and finishing drywall. Gloves, goggles, and a dust mask are needed when handling insulation, and the garage needs proper ventilation. If you are unsure how to meet those precautions, have a professional handle the work.
Frequently asked questions
- Is insulating garage walls a reasonable DIY project?
- Yes, it can be a DIY project, but it is moderately difficult and includes drywall finishing as well as insulation work. Before deciding, consider your comfort with a utility knife, screwdriver, staple gun, and drywall tools. Hire a professional if any part is outside your skills or you are unsure about handling insulation with protective gear and proper ventilation.
- What makes garage wall insulation more expensive?
- The price scales with the wall area being insulated, the labor time, and the materials used. Insulation, drywall, drywall screws, tape, and joint compound all contribute to the material scope; the drywall finishing work also contributes to labor.
- What should I check before buying garage wall insulation?
- Check the wall construction first to determine the appropriate insulation type rather than choosing solely by the amount needed. Measure the wall area to calculate both insulation and drywall quantities. Fiberglass insulation is an option for this work, but the wall assessment should come before purchasing.
- Can I cover existing wall cracks and gaps with insulation?
- Cracks and gaps should be identified and filled before insulation goes between the studs. Treat them as preparation work, and seal them before the insulation and drywall cover them.
