Dabella did windows and a shower in my home. Their salesperson Heather Hanson is very good at explaining the process and helpful afterwards with any help i needed. I'm very happy with the quality of the product and the craftsmanship on the installation.

Doorbell Installation questions, answered by experts

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

It is generally completed in a day, depending on the attic size and access difficulty.

The most insulative type of insulation for behind drywall is spray foam insulation, but this is the most expensive insulation available. The most common insulation—sometimes considered the best for the value you get for the money—is fiberglass roll or fiberglass batt insulation, which is significantly more affordable but also far less insulative. The best kind of insulation for your house will also vary based on the climate in your area, your budget, and more. A professional insulation company can help you decide which type is best for your home.

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.

Insulating windows with plastic works, but it can be time-consuming, and the end results can—and often do—end up lacking in aesthetics. Window film and caulking your windows to make sure there are no drafts are two options that increase the energy efficiency of your home in a low-cost way. Plastic can be a good strategy while you consider alternatives.
