Existing Side Wall Insulation
Insulating the side walls of your home is one of the most effective ways to improve energy efficiency, indoor comfort, and overall structural performance. At All Weather Insulation, we specialize in upgrading insulation for existing homes, helping homeowners reduce energy bills and enhance year-round comfort without the need for major renovations. If your home was built before modern energy codes were established, chances are your side walls may be under-insulated—or not insulated at all.

What Is Existing Side Wall Insulation?
Existing side wall insulation involves adding insulation to the exterior walls of a home that has already been built. This process is typically done from the inside or outside of the home without removing any existing wall structures. Using advanced methods such as blown-in cellulose or dense-pack fiberglass, insulation is injected into the wall cavities to fill gaps and voids that allow heat and cold to pass through.
This method is minimally invasive and highly effective, offering excellent thermal resistance (R-value) and improved soundproofing. It’s a smart upgrade for any homeowner looking to enhance energy performance without undertaking a full remodel.

How the Process Works
At All Weather Insulation, we follow a precise and professional approach to insulating existing side walls:
Inspection & Assessment
Our team begins with a detailed inspection of your home’s exterior walls. Using thermal imaging and other diagnostic tools, we identify voids, existing insulation levels, and areas where improvements are needed.
Drill & Fill Method
For most homes, we use the drill-and-fill technique. Small holes are drilled either in the interior drywall or the exterior siding (depending on your preference and wall type). We then use specialized equipment to blow insulation into the cavities, ensuring complete and even coverage.
Patching & Finishing
Once the insulation is installed, we patch up the holes and restore the surface to its original condition. If applied from the exterior, we reattach or replace siding as needed to maintain curb appeal.
Final Inspection
After completion, we conduct a final walkthrough and quality check to ensure your walls are properly insulated and that everything looks just as it did before we started.
Why Existing Side Wall Insulation Matters
Many older homes—especially those built before the 1980s—have little to no insulation in the side walls. Even if your home does have insulation, it may have settled or deteriorated over time, leaving large voids that compromise comfort and efficiency. Proper side wall insulation offers numerous benefits, including:
- Lower Energy Bills: Insulated walls reduce heat loss in winter and heat gain in summer, decreasing the load on HVAC systems and cutting monthly energy costs.
- Enhanced Comfort: Insulated walls help eliminate cold drafts and hot spots, making indoor temperatures more consistent throughout the home.
- Noise Reduction: Wall insulation helps reduce outside noise, making your indoor environment quieter and more peaceful.
- Moisture Control: High-quality insulation helps prevent condensation buildup within wall cavities, reducing the risk of mold, mildew, and wood rot.
- Increased Home Value: Energy-efficient upgrades like insulation can boost property value and appeal to potential buyers.
