How To Insulate a Wall Without Removing the Drywall: Steps by the Pros

Wall with insulation installed

When many people think of home insulation, they imagine rolls of insulation between the beams of a house. As such, it might seem impossible to install insulation for an exterior wall of the house without having to cut away the drywall.

Fortunately, if you know how to insulate a wall without removing the drywall, you can save time and money on your insulation project. Anthem Insulation & Home ranks among the best-known and most trusted wall and floor insulation contractors in Woodstock, GA. They know the professional secrets to effective, stable insulation without having to redo drywall.

Don’t feel like you have to ruin your interior design by ripping down your walls and covering furniture in dust and debris. Don’t put off installing quality insulation and wind up paying skyrocketing bills this winter. Protect yourself by learning how to insulate a wall without removing the drywall.

Choosing the Right Insulation

Homeowners can insulate their homes in many ways, using many different types of insulation. Using the right insulation and the proper professional insulation technique allows you to protect your home from the cold without tearing down and rebuilding walls. 

Spray Foam Insulation

Spray and foam insulation can be more convenient if you already have drywall in place because you only need a small opening to insert the drywall.

Roll / Batt Insulation

Roll and batt insulation are two types of insulation you can apply to your walls. Roll insulation consists of long sheets that you can cut to the height of your walls, while batt consists of squares of insulation. Both types of insulation take up space, so they prove more of a challenge to apply to a wall once the drywall is in place.

Insulating Ground Floor Exterior Walls

The easiest way to install insulation on an exterior wall at the ground floor level of a home without going through the drywall involves removing some of the exterior siding and applying foam insulation behind the drywall. Cover the opening with a tarp to prevent rainwater or debris from getting to the insulation during the job. 

Adding insulation to a second-story wall through the house’s exterior adds some difficulty because you will be working off the ground.  

Insulating Finished Attics

Even though many homeowners often leave attics unfinished, they still may need to improve the insulation in their attics after installing the drywall. Perhaps a previous owner installed the drywall and forgot to put in enough insulation. Even so, the problem proves easy to fix with some patience.

Eventually, your roof will need repair or replacement. When it does, add foam insulation, roll, or batt insulation after you or your contractor has torn off the roof. If you don’t want to wait, you could make a small opening in the roof and add foam insulation. However, it might be more difficult than drilling openings in the drywall and patching them up.

Insulating Finished Basements

The best way to install insulation is before you finish the basement and install drywall. However, with an already-finished basement, you can still add insulation without damaging the drywall.

It might seem like a puzzle learning how to insulate a wall without removing the drywall if you can’t get to it from the outside. Your best option might be to gain access to the space from above and add spray foam insulation.

Insulate Other Parts of the House

Knowing how to insulate a wall without removing the drywall also means recognizing other ways that heat can leave your home. You can improve your home’s ability to retain heat by insulating other areas as well, such as:

  • Pipes
  • HVAC ducts
  • Windows
  • Doors

If you slow down the loss of heat from your home by sealing off other avenues of escape, you might be able to bring heating costs down without having to fix the insulation in your walls at all.

Hanging decorative materials such as carpeting or tapestries on the wall will reduce heat loss as well. It also works to add curtains and some other window treatments.
