## Wall insulation for existing homes Twin Cities homes built before 1960 often have **empty wall cavities** or a couple inches of settled material. You can fix that without gutting the house. ### Dense-pack retrofit We drill access holes, blow cellulose or fiberglass into each cavity under pressure until it packs solid, then plug and patch. Access is either from the exterior (siding panels removed and reinstalled, or holes plugged and painted) or from inside. Dense-pack does two jobs at once: it insulates, and at proper density it substantially slows air movement through the wall. ### Rim joist — the highest-value 4 hours in your basement The rim joist is the band of framing at the top of the foundation wall, around the whole perimeter of the house. In most homes it is either bare or has a fiberglass batt stuffed against it doing almost nothing. It is typically the largest single air leak in a Minnesota house. The fix is 2 inches of rigid foam cut to fit each bay, sealed at the edges with spray foam. It is a one-day job on most homes and homeowners consistently report the basement and first floor feeling different immediately. ### What we do - **Dense-pack cellulose or fiberglass** into existing wall cavities - **Rim joist rigid foam and sealing** around the full perimeter - **Cantilever and bay window floors** — the classic freezing-floor spot - **Knee walls and slopes** in story-and-a-half homes - **Basement wall insulation** — rigid foam with framing, done so it dries properly - **Crawlspace** insulation and encapsulation ### Planning ranges (Twin Cities, estimates) | Work | Typical range | |---|---| | Dense-pack walls, average home | $3,500 – $9,000 | | Rim joist foam and seal | $1,200 – $2,800 | | Cantilever floor insulation | $600 – $1,800 | | Basement wall, rigid foam and framing | $4,000 – $12,000 | | Crawlspace encapsulation | $3,000 – $9,000 | Estimates for planning; siding type and access drive the range. ### One important warning Do not insulate a wall you know is getting wet. Filling a cavity that has a leak turns a drying wall into a rotting wall. If there is water staining, failed flashing, or a known leak, that gets fixed first. We check before we fill.
