Homes throughout Boulder, Golden, and Front Range often contain insulation that has settled, been damaged by moisture, or become contaminated by pests over time.Sometimes adding insulation is the wrong move. If what is up there is contaminated, soaked, smoke damaged, or so degraded that it has stopped working, burying it under new material traps the problem and charges you for the privilege.

We remove old insulation, clean and treat the space, air seal it properly, and install new. It is a full reset of the attic or crawl space rather than a cosmetic one.

When Removal Is the Right Call

Rodent contamination

This is the most common reason we pull an attic. Mice and squirrels nest in loose fill and batts, and what they leave behind does not go away on its own. Insulation that has been used as a nest carries droppings, urine and odor, and it has been compressed and tunneled to the point where its R-value is largely theoretical.

You cannot fix this by adding material on top. The contamination stays, the smell stays, and now it is buried where nobody can get at it.

Water damage

Roof leaks, ice dams, failed plumbing, or a bathroom fan venting into the attic instead of outside. Wet insulation loses most of its R-value and does not fully recover when it dries. It also holds moisture against your framing and sheathing, which is a much more expensive problem than insulation.

Smoke and fire damage

Insulation holds smoke odor indefinitely. Even where there is no visible damage, the material has to come out or the smell keeps coming back through every ceiling penetration in the house.

Age and degradation

Material that has settled to the point of uselessness, been walked through repeatedly, or was installed with a vapor retarder facing the wrong direction. Sometimes the honest answer is that what is up there has nothing left to contribute.

What Removal Actually Involves

1. Assessment and photographs. We go up, document what is there, and show you before anything is quoted. You should never be asked to approve a removal you have not seen.
2. We protect the access point and the path through your home so material does not end up in your living space.
3. Removal by commercial vacuum into sealed bags, hauled off site.
4. Cleaning and treatment. Where there has been rodent contamination we treat the space with DSV disinfectant, which handles the bacteria and the odor rather than masking it.
5. Air sealing. With the attic stripped to the deck, every top plate, penetration, chase and fixture is visible and accessible. This is the single best opportunity your house will ever get for a complete air seal, and it is the reason a remove and replace often outperforms what the homeowner expected.
6. Baffles, ventilation correction, hatch detail.
7. New insulation installed to your jurisdiction’s requirement, at even depth, with depth gauges

Vermiculite and Asbestos

Vermiculite insulation, which looks like small grey-brown pebbles, sometimes contains asbestos. It shows up mainly in homes insulated before the 1990s, and it is less common in this market than people expect, but it does turn up.

We do not perform asbestos abatement and we will not guess. If there is any doubt about what is in your attic, we refer you to a trusted testing partner before anyone disturbs it. If the test comes back clean, we proceed with the work as scoped. If it does not, the testing party is licensed to advise you on next steps and we stay out of the way until that is resolved.

Any contractor who offers to haul vermiculite out without testing it first is doing something you do not want done to your house.

Most Removals Start as Something Else

Very few people call an insulation company asking to have insulation taken out. They call because the upstairs is cold, or because they heard something in the ceiling, and removal comes up once we are actually in the attic looking at it.

That is why we photograph everything before we quote. You get to see what we saw and decide for yourself whether it comes out or gets added to. We will tell you which one we would do if it were our house, and we will tell you when adding is genuinely the better value.

Free assessment, photographs, and a written scope. Three certified BPI analysts on staff and over 340 five star reviews across the Front Range.

Why Choose Koala Insulation of Boulder

CCEF Approved Contractor

Koala Insulation of Boulder is an approved contractor with the Colorado Clean Energy Fund. That means our customers can finance insulation work through RENU loans and ClearPath On-Bill financing, with terms built specifically for energy efficiency improvements rather than a generic home improvement loan.

Not every insulation contractor in Colorado carries this approval. Ask us about it on your estimate, and we will walk you through what you qualify for.

Limited Lifetime Warranty

Our work carries a limited lifetime warranty. In practice, it is simpler than that sounds. If we did the work on your home and something is not right, you call us, and we come back and fix it. No claim forms, no argument about what is covered.

Three Certified BPI Analysts on Staff

The Building Performance Institute certifies professionals to assess how a home performs as a complete system: air leakage, insulation, ventilation, moisture, and combustion safety. Most insulation companies do not employ a single certified analyst. We have three.

It is the difference between someone who can install insulation and someone who can tell you why your house is uncomfortable in the first place.
