Johns Manville Insulation Removal in Dallas: What to Know First

Johns Manville insulation removal in Dallas typically runs $1.50 to $3.50 per square foot depending on material type, attic access, and the condition of what’s up there.

Call (940) 748-1726

This page is for Dallas homeowners who have Johns Manville insulation in the attic or walls and suspect it’s compromised. Water damage, rodent activity, old JM batt products that settled decades ago, or spray foam that was never installed right. If that sounds like your house, call (940) 748-1726 and we’ll schedule someone to look.

How Johns Manville Products Fail – and How We Fix Them

• JM fiberglass batts losing their R-value. Older Johns Manville batt lines, including ComfortTherm and the legacy R-19 and R-30 products, sag over time. Once the batt pulls away from the drywall, you get thermal bridging and cold spots. In Dallas attics where summer heat hits 140°F plus, degraded batts can’t hold their stated R-value. We remove the old material, check for air leaks, and install fresh blown-in or batt insulation to the right depth for our climate zone.
• Waterlogged JM loose-fill fiberglass. A roof leak or AC condensation leak saturates loose-fill and it mats down. Once Johns Manville loose-fill gets wet, the R-value collapses and it’ll never dry back to original performance. We see this a lot in older Dallas homes around the M Streets and Casa Linda where roof penetrations go unnoticed. We extract the wet material, dry the attic, and seal the source before reinstalling.
• Rodent-contaminated insulation. Rats, squirrels, and mice tunnel through JM batts and loose-fill, leaving droppings and urine throughout the attic. This is a removal job, full stop. We clear the contaminated material, sanitize the space, seal entry points, and install fresh insulation. The crew wears full PPE from start to finish.
• JM spray foam that was misapplied. We’ve pulled out Johns Manville open-cell spray foam in Dallas homes where the installer applied it too thin or missed entire cavities. JM Corbond III is a solid product when applied correctly, but a botched install leaves gaps that air moves right through. Removal and correction means cutting out the bad sections, verifying the framing is sound, and respraying or switching to a blown-in system depending on the structure.
• Old JM board insulation in wall cavities. Some older Dallas homes have Johns Manville rigid board or batts with the old kraft facing that’s torn or missing. Once the vapor barrier is compromised, you get moisture in the wall cavity and mold risk. We open the affected sections, pull the damaged material, remediate, and rebuild the cavity with the proper product.
