Yes, you can vacuum out attic insulation using a specialized, heavy-duty insulation removal vacuum. This method is highly recommended over bagging by hand as it saves a significant amount of time and safely deposits the old insulation directly into large collection bags or dumpsters outside your home.
Professional insulation vacuuming and removal typically costs between $1 and $2 per square foot, with total project prices generally ranging from $800 to $2,500 depending on your attic's size.
In a 1,500-square-foot attic, it could take 6 to 15 hours to remove the cellulose with the proper equipment. It's going to be an extremely long and dirty process. With every bag you fill, make sure to squeeze out the air inside before tying the bag shut.
Fiberglass insulation does not stay in the lungs permanently. Unlike asbestos, which the body cannot break down, fiberglass particles are generally cleared out by the lungs' natural defenses (macrophages) within about 10 days to a few weeks.
Yes, mice love blown-in insulation. Because it is soft, warm, and easy to burrow through, materials like loose-fill fiberglass provide an ideal environment for nesting and breeding.
The Amish control mice through non-chemical, self-sustaining methods, relying on active trapping, natural scent repellents, and structural exclusion. Rather than using commercial poisons, they focus on physical barriers and natural predators to keep rodent populations in check.
No, mice typically do not leave the attic during the day. Because they are nocturnal, mice spend daylight hours sleeping and hiding in their nests. They wait until dark to venture out and scavenge for food.
Short-term Exposure
The symptoms of irritation are often nonspecific, temporary, and may include itching, coughing, or wheezing. High levels of exposure to airborne fiberglass may aggravate existing asthma or bronchitis-like conditions.
Treatment may involve administering oxygen, whether through a mask, the nose, or through a tube; a bronchoscopy to view damage to the airway or suction debris and mucus; as well as medications or inhalers. While the lungs can heal to a certain extent, not all damage is reversible.
The best non-toxic insulation is either mineral wool or foam insulation inserts.
Removing and replacing 1,800 sq. ft. of attic insulation costs between $5,400 and $10,800 on average, with most homeowners paying around $3.50 to $7.00 per square foot for full-service removal, air sealing, and new installation.
Adding more insulation does not always make a house warmer because insulation only slows heat transfer. Homes with major air leaks, moisture problems, unsealed rim joists, or empty wall cavities can still feel cold even with attic insulation rated at R-38 or R-49.
Buyers often walk away from homes with spray foam insulation because it can cause major mortgage and insurance denials. The foam tightly seals roof spaces, trapping moisture, and covers up structural timbers. This makes it impossible for surveyors to inspect for hidden rot or damage, which can lead to catastrophic repair costs.
Not always. If your existing insulation is dry, mold-free, and undamaged, you can usually leave it and add new insulation right on top to save money. However, full removal is necessary if the old material has water damage, pest infestations, or if you are switching to spray foam.
Most homeowner's insurance policies generally do not cover the expenses of regular maintenance or voluntary attic restoration for non-insurable reasons, such as adding living space or increasing the home's value. Your homeowner's insurance policy may provide specific coverage limits for certain types of damage.
Insulating a 1,600 sq ft house typically costs between $1,600 and $7,200 for professional installation. Costs average about $1.00 to $4.50 per square foot, heavily dependent on the material chosen, the difficulty of accessing the space (e.g., attics vs. enclosed walls), and whether you need to pay for old insulation removal.
Yes, lungs blackened by smoking can regain a healthier, pinkish appearance and improved function after quitting, though some damage may be permanent. While lung tissue damaged by diseases like coal miner's pneumoconiosis cannot heal, smoking cessation allows the lungs to clear tar and repair cells over months or years, significantly reversing damage.
Early lung damage often develops gradually and can easily be mistaken for aging or being out of shape. The most common indicators include persistent shortness of breath, a chronic cough, frequent respiratory infections, and unexplained fatigue.
The first signs of dust inhalation are your body's immediate defense mechanisms kicking in to expel foreign particles. Initial symptoms typically include a scratchy throat, dry cough, sneezing, a runny or stuffy nose, and eye irritation (such as redness or itching).
Inhaling a small amount of insulation (like fiberglass) typically causes temporary, localized irritation. You may experience coughing, sneezing, a sore throat, or mild wheezing as your body clears the microscopic glass shards. It usually does not cause permanent damage if it is a one-time, minor exposure.
Inhaled fiberglass is primarily expelled from the lungs within several days to 3-6 weeks. The body's natural defense mechanisms—such as coughing, sneezing, and the action of lung cells called macrophages—break down and clear most particles that reach the lower respiratory tract.
The smell of fiberglass itself is rarely toxic, as pure glass is solid and odorless. However, the chemical odor often associated with it typically comes from binders (like formaldehyde) or resins off-gassing. While usually not dangerous in small amounts, these fumes can cause temporary headaches, nausea, and throat irritation.
Yes, mice can and occasionally do crawl on sleeping people. While mice are naturally skittish and prefer to avoid humans, they are nocturnal and excellent climbers. If your sleeping body is in their path—or if you leave crumbs or food odors on your bed—they will readily scurry across you.
If you see one mouse, pest experts estimate there are likely 5 to 10 more hiding, as mice are social and rarely live alone. Because they can reproduce rapidly—one female can have up to 10 litters of 5 to 6 pups per year—what starts as one mouse can quickly multiply.
Mice most commonly invade homes during the late fall and winter months (typically from October through February) when dropping outdoor temperatures prompt them to seek warmth and food. However, they can also sneak in during the summer to escape extreme heat and find water.
