Insulate existing walls without removing drywall
Dense-pack cellulose or blown-in fiberglass fills cavities completely
Dramatically reduces drafts and temperature inconsistencies
Minimally invasive — small access holes are patched after installation
Ideal for older Denver homes with empty wall cavities
May qualify for Xcel Energy rebates
A proven, methodical approach refined over 20+ years of professional installation.
We inspect your walls to determine whether cavities are empty or under-insulated, identify any obstacles, and plan the access point locations.
Small holes are drilled at strategic locations (interior or exterior) to access each wall cavity. We carefully work around electrical, plumbing, and fire stops.
Insulation is blown into each cavity at high density, filling around wiring, plumbing, and blocking for complete, gap-free coverage.
All access holes are patched and finished to match your existing wall surface, leaving no visible evidence of the installation.
Many Denver homes built before the 1980s have little to no wall insulation, resulting in massive energy loss and uncomfortable temperature swings during Colorado's extreme winters and summers. Traditional wall insulation requires removing drywall — an expensive, disruptive process that most homeowners want to avoid. Wall insulation retrofitting solves this problem by injecting dense-pack cellulose or blown-in fiberglass into existing wall cavities through small access holes drilled from the interior or exterior. The insulation fills the cavity completely, flowing around wiring, plumbing, and blocking to create a tight thermal barrier. The access holes are then patched and finished, leaving no visible trace of the installation. Sky Insulation provides professional wall insulation retrofit services for Denver homeowners looking to improve comfort and reduce energy costs without a major renovation. This is one of the most effective upgrades for older homes, and may qualify for Xcel Energy rebates as part of a whole-home efficiency improvement.
Dense-pack insulation is injected through small access holes, avoiding the cost and disruption of tearing out and replacing drywall.
Empty wall cavities are a major source of drafts in older Denver homes. Filling them with dense-pack insulation creates a tight thermal barrier.
Wall insulation retrofit can reduce your heating and cooling costs by 15–20%, with the biggest impact during Denver's extreme winter and summer months.
Insulated walls create more consistent temperatures throughout your home — no more hot and cold rooms or temperature swings.
We drill small access holes (about 2 inches) at strategic locations in each wall cavity, then inject dense-pack insulation using specialized equipment. The insulation fills the entire cavity, and the holes are patched and finished afterward.
Common signs include drafty rooms, walls that feel cold to the touch in winter, significant temperature differences between rooms, and high energy bills. Many Denver homes built before the 1980s have empty or poorly insulated wall cavities.
We patch all access holes with matching material and finish them to blend with your existing wall surface. In most cases, the patches are not noticeable after painting.
Both are effective. Dense-pack cellulose has slightly better air infiltration resistance and is made from recycled materials. Blown-in fiberglass is moisture-resistant and non-settling. We'll recommend the best option for your specific situation.
