Insulation questions, answered by experts

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

Winterizing your outdoor plumbing keeps your outdoor spigot from freezing and potentially bursting. This includes draining residual water out of the pipe and spigot after turning the valve off, then removing garden hoses and other attachments from the spigot before winter comes. Insulating the pipe that leads to the spigot and installing a freeze-proof faucet also help, as does installing an outdoor faucet protector.

The cost to rent an insulation vacuum ranges between $250 and $350 per day. The price will increase if you choose to rent for additional days, but you may get a discounted daily rate if you rent it for a whole week, which could cost up to $1,000. Once you've removed the insulation and are ready to replace it, the cost to rent a blown-in insulation machine ranges between $100 and $500.
