When Is Insulation Removal Necessary?

Insulation Removal Perth is an important investment in your home’s comfort and energy efficiency. But when is it necessary and how is it best done?

Start by turning off the power to the attic and disconnecting any live wires. Be sure to spread plastic over furniture and equipment in the living space to prevent dust from spreading.

Insulation that is wet or damaged should be removed immediately, as it will likely cause damage to the rest of your home. Moisture will seep through rotted or moldy insulation and eventually find its way into walls, ceilings and floors where it can lead to structural problems and serious health concerns. Removing insulation that is wet or damaged will help to prevent water leaks, mold and rot in your home, as well as lower energy bills.

When you schedule insulation removal, your contractor will take the appropriate safety precautions to protect themselves and the rest of your home. They’ll be able to use professional equipment like commercial grade insulation vacuums that will remove your old insulation more quickly and efficiently than a shop vac can. The specialized equipment used by 1907 Insulation is designed to quickly and easily remove loose fill, cellulose or fiberglass insulation without harming the surrounding drywall or other materials in your attic.

Another reason that you may need to have your insulation removed is if it has become contaminated by pests or smoke. Generally, these contaminants need to be removed before any new insulation can be added. Contaminated insulation can contain urine and feces from rodents such as rats, squirrels and raccoons, which can then infiltrate the living areas of your home. This type of contamination also includes pheromones from dead animals that can trigger respiratory issues in your family.

Smoke can also contaminate your insulation, which can lead to unpleasant odors in your home. If your attic insulation has been exposed to smoke, it will need to be removed and replaced as soon as possible to reduce the odors. This will also prevent the smells from absorbing into the rest of your home’s materials and affecting your health and comfort. Removing contaminated insulation can also make it easier to install new insulation that will be able to regulate your home’s temperature, which can lead to lower utility bills and greater comfort throughout the year.


When insulation gets wet, it can be a perfect home for mold. This is especially true if there are leaks in the roof and walls that allow water to seep into areas where insulation is located. The moisture in these areas can cause the growth of green, black or white mold. When this happens, it is important to remove the contaminated insulation and replace it. Moldy insulation is a health risk and can also cause damage to the framing of the wall or other parts of the home.

There are several types of mold that can grow in fiberglass insulation. Most of these are variations of the green fungus called Cladosporium, Penicillium or Aspergillus. The appearance of these fungi on the surface of the insulation can be identified by their distinct hues of green and powdery texture. Other discoloration of the insulating material may indicate that other types of dirt or dust have contaminated the insulation.

The best way to test the presence of mold in insulation is to hire a professional to conduct a mold inspection. Mold testing will help determine the exact type of mold and the spore count in the air. This information will help homeowners decide if the mold is toxic or not and what measures need to be taken.

In most cases, it is necessary to remove all of the contaminated insulation and clean the area with a pressure washer or chemical spray cleaner to prevent the spread of the mold to other areas of the home. Then the contaminated materials can be properly disposed of outside of the house in contractor trash bags. If the insulation is in an attic, it can be swept and dusted with a wire brush, then sprayed down with a cleaning solution of one cup of bleach to disinfect it.

If the contaminated materials are in good condition and there is no visible damage to the drywall or framing of the wall, it is possible to use a fungicidal mold encapsulant to seal the mold and keep it from growing again. Otherwise, the materials should be replaced with new insulated materials.

Unusual Smells

When a home has been insulated with tainted insulation, that odor can linger in the air. Especially when that old insulation has been blown into the duct system, those smells get circulated throughout the house. If you have a musty, mildewy, or just generally unpleasant odor, it could be from tainted insulation. The best way to tell is by putting your nose over the top of the attic space and sniffing. If it smells like that, it’s time to remove the old insulation and replace it with new, clean material.

It’s important to have the right equipment for this type of project, so working on the attic can be completed safely and efficiently. A good pair of rubber-coated gloves will protect your hands, while a respirator will help you avoid the potentially harmful fiberglass dust particles. It’s also a good idea to wear a hard hat and some sort of eye protection, as well.

The preferred method for removing old, blown in insulation is to use a vacuuming process. A professional will bring in a machine with a long hose to be able to reach the whole attic area and suck up all the old, contaminated insulation material. This is much faster and more efficient than the manual removal of batt or rolled insulation.

Another reason to remove old insulation is when it’s contaminated with mold, mildew, or animal droppings. Insulation in attics is often targeted by wildlife that’s looking for a warm, dry place to live and raise their young. This can leave behind all sorts of bacteria and other health risks for the homeowner. Those dangers can linger and even spread to other areas of the house if not taken care of immediately.

It’s also important to note that if the insulation in the attic is damaged, it’s likely that the same issues will be found throughout the home. Insulation in walls that has been displaced by leaks or water damage will also need to be removed and replaced with clean, fresh material.

Health Concerns

Insulation can provide many health benefits, but it can also pose a risk. This is particularly true when old insulation becomes contaminated. Whether from water damage, mold, mildew, rodents or other pests, contaminated insulation can cause a wide range of issues that can affect your home’s indoor air quality. When this happens, it’s important to remove the contaminated insulation and replace it with new, healthy materials.

The main way that old insulation poses a health risk is when its tiny, needle-like fibers become airborne. This can happen when loose-fill insulation is removed, as well as with exposed blanket batts or rolls and damaged blown-in insulation. When the fibers are inhaled, they can lead to health issues such as respiratory problems and cancer.

Another potential health concern with older insulation is that it may contain asbestos or other hazardous materials. This is especially true of cellulose insulation, which was often used in homes built before the 1980s. If you suspect that your home has this type of insulation, it’s crucial to hire a professional contractor who can properly test and dispose of the material.

If the attic space isn’t cleared out beforehand, it can be dangerous to work in during the insulation removal process. In addition, it’s crucial to have the proper equipment for the job, including a ladder, a wet/dry vacuum or HEPA vacuum, and plenty of garbage bags. It’s also important to wear protective gear, such as gloves, a mask and long sleeves and pants. This will prevent the contaminates from spreading throughout your living spaces and into your lungs, where they can make you sick.

It’s also a good idea to turn off the power or disconnect any live wires before beginning the process. This will help reduce the risk of electrical shock or fires and ensure that the workers are safe from harm. This is an essential safety precaution that’s often overlooked. Working around live wires can be extremely dangerous and should only be done by experienced professionals who follow the appropriate safety protocols.
