Therefore, if you're unsure about your ability to install insulation properly or safely, or if you're planning a large-scale project, it's generally a good idea to consult with a professional insulation contractor like Draft Stoppers who can help ensure that the insulation is installed correctly and safely.

 

  

6. How much does home insulation cost? 

 

The cost of home insulation can vary widely depending on a number of factors, including the size of the home, the type of insulation being installed, and the method of installation.

 

Here are some rough estimates for different types of insulation:

 

• Fiberglass batt insulation: $0.64 to $1.19 per square foot installed
• Cellulose blown-in insulation: $1 to $1.50 per square foot installed
• Spray foam insulation: $1.50 to $3 per square foot installed - Cost of Spray Foam Insulation

 

It's important to note that these are just rough estimates, and the actual cost of insulation can vary depending on the specific circumstances of the installation. Additionally, there may be other costs associated with insulation installation, such as the cost of removing old insulation or the cost of repairing any damage that occurs during the installation process.

 

It's always a good idea to get multiple quotes from reputable insulation contractors to get a more accurate idea of the cost for your particular project.

 

  

7. How long does home insulation last?

 

The lifespan of home insulation depends on several factors, including the type of insulation, the quality of the installation, and the conditions in which it is installed. Here are some general guidelines for how long different types of insulation can last:

 

• Fiberglass insulation: Fiberglass insulation typically has a lifespan of 10 to 25 years, depending on the quality of the installation and the conditions in which it is installed.

• Mineral wool insulation: Mineral wool insulation can last up to 100 years or more.

 

It's important to note that these are just general guidelines, and the lifespan of your home insulation will depend on many factors. To ensure that your insulation lasts as long as possible, it's important to have it installed by a professional like Draft Stoppers and to maintain it properly over time.

 

  

8. How can I tell if my home needs insulation? 

 

There are several signs that can indicate whether your home needs insulation:

 

• High energy bills: If your energy bills are consistently high, it could be an indication that your home is not well-insulated. Insulation helps keep your home warm in the winter and cool in the summer, reducing the amount of energy needed to maintain a comfortable temperature.
• Uneven temperature: If certain rooms in your home are significantly cooler or warmer than others, it could be a sign of insufficient insulation. Insulation helps even out the temperature throughout your home.
• Drafts: If you feel drafts or cold spots in certain areas of your home, it could be a sign that your home is not well-insulated. Insulation helps prevent air leaks and drafts.
• Mold or mildew: If you notice mold or mildew growing in your home, it could be a sign of poor insulation. Insulation helps prevent moisture from getting into your home, which can lead to mold growth.
• Noisy rooms: If you can hear outside noises or noises from other rooms in your home more than you should, it could be a sign of poor insulation. Insulation helps reduce noise transmission.

 

If you notice any of these signs, it may be time to have a professional like Draft Stoppers inspect your home's insulation and make any necessary improvements.

  

9. Can home insulation be removed?

 

Yes, home insulation can be removed, but the process can be difficult and time-consuming, depending on the type of insulation that was installed.

 

For example, loose-fill insulation such as fiberglass or cellulose can be removed using a vacuum or blower equipment, which can suck out the insulation from the walls or attic. However, it can be difficult to remove all of the insulation material, especially if it has settled or compressed over time.

 

Batt insulation, such as fiberglass or rock wool, can also be removed, but it may require cutting and removing the batts manually. This can be a labor-intensive process, and it can also damage the walls or ceilings where the insulation was installed.

 

Spray foam insulation can be more challenging to remove, as it adheres to surfaces and can be difficult to remove without damaging the underlying structure.

 

Overall, the removal of insulation should only be undertaken by a professional insulation contractor like Draft Stoppers who has experience in the safe removal of insulation materials and the disposal of hazardous materials. It is also important to ensure that any new insulation that is installed meets local building codes and standards for energy efficiency.

 

  

10. Will adding insulation to my home increase its resale value?

 

Adding insulation to your home can potentially increase its resale value, but the extent to which it does will depend on various factors such as the local real estate market, the age and condition of your home, and the quality and type of insulation you install.

 

In general, insulation is considered an energy-efficient upgrade that can make a home more comfortable and reduce heating and cooling costs for the homeowner. This can be a selling point for potential buyers who are interested in saving on their energy bills. Additionally, many home buyers are becoming increasingly aware of the environmental impact of their home and may be more interested in homes that are energy-efficient and have a smaller carbon footprint.

 

However, it's important to keep in mind that the resale value of your home will also depend on other factors such as the overall condition of your home, the location, the size, and the amenities it offers. Therefore, adding insulation alone may not necessarily guarantee an increase in resale value.

 

According to a study by the National Association of Realtors, adding insulation to an attic is one of the best home improvements that can add value to a home. The study found that homeowners can recoup an average of 108% of the cost of attic insulation in added home value when they sell their home.

 

If you're considering adding insulation to your home with the aim of increasing its resale value, it's a good idea to consult with a local real estate agent or appraiser to get a better understanding of the local market and what buyers are looking for in a home. They can provide valuable insight on whether this upgrade is likely to be a worthwhile investment for you.
