Basement Insulation: Why It Matters and How It’s Done

Insulating the basement of your Kansas City home is easy to put on the back burner. There are other more urgent or important ways and places to spend your money. And, you’ve lived with your uncomfortable basement this long; a few more months or years won’t make a difference. Or, you might not know exactly how under or poorly insulated your basement is because you’ve adapted. Or, you assume the builder or previous owner used proper techniques to install sufficient insulation, so it’s as good as it’s going to get.

Having insulated thousands of basements in a variety of houses across the KC metro, the A+ Insulation team has heard all the reasons why basement insulation is overlooked. We think once you have a better idea of why insulating your basement matters and how it’s done, you’ll understand how this area plays a crucial role in your home’s overall energy efficiency and your personal comfort.

Why is Insulating Your Basement Important?

The top five reasons basement insulation matters are:

1.      Energy efficiency
2.      Enhanced comfort
3.      Moisture and mold prevention
4.      Soundproofing
5.      Increased home value

Energy Efficiency

One of the main reasons to insulate your basement is energy efficiency. An uninsulated basement can lead to significant heat loss in the winter and heat gain in the summer. This inefficiency forces your furnace and air conditioner to work harder, leading to higher utility bills, not to mention wear and tear, leading to early HVAC system replacement. Proper insulation helps maintain a stable indoor climate, reducing the need for frequent heating or cooling. In turn, you’ll see a decrease in your utility bills of up to 30 percent.

Enhanced Comfort

An uninsulated basement is often the most uncomfortable space in a home, especially in the winter when it’s colder than other rooms on higher floors. Insulation moderates these swings, making the basement a more livable and inviting space. This transformation allows homeowners to use their basements more effectively, whether as a recreational area, home office or additional living space any time of year.

Moisture and Mold Prevention

Basements are naturally prone to dampness because they are below ground. This moisture can lead to mold and mildew growth, which are harmful to both your home’s structure and your family’s health. Insulation, like spray foam, or other insulation types, particularly when combined with a vapor barrier, reduces moisture infiltration, protecting your home from these risks.


Insulating your basement also has the added benefit of soundproofing. This is especially useful if your basement is used as a living space, home theater or music studio, as it minimizes noise transfer between floors, creating a quieter overall home environment.

Increased Home Value

A well-insulated basement can be a key selling point for potential home buyers. It reflects on how well you cared for your house and that it is energy-efficient and comfortable, potentially leading to a higher resale value.

How to Properly Insulate Your Basement

For best performance, basement insulation has to be properly installed. The steps to follow are:

1.      Conduct a thorough inspection
2.      Choose a professional insulation installer or do it yourself?
3.      Select the right basement insulation material
4.      Insulate walls (and vapor barrier)
5.      Insulate ceilings
6.      Seal air leaks

Conducting a Thorough Inspection

The first step in basement insulation is a thorough inspection. An A+ Insulation expert assesses your basement for any existing insulation, moisture levels and potential air leaks. This evaluation is crucial to determine the most effective insulation strategy for your space.

Professional Installation

While some homeowners may consider a DIY approach, professional installation by A+ Insulation ensures that the job is done correctly and safely, not to mention saving you a tremendous amount of time. This is particularly important if you’re addressing any additional issues, such as mold, structural problems or complex insulation challenges.

Selecting the Right Insulation Material

There are several insulation materials suitable for basements, including fiberglass batts, foam board and spray foam. Each has its own advantages and is selected based on the specific needs of your space. For example, fiberglass is a cost-effective option for standard spaces, foam board is excellent for moisture resistance, and spray foam offers superior air sealing and insulation properties, plus it keeps out insects and other pests that could find a way into your basement.

Wall Insulation

Basement walls are one of the primary sources of heat loss. Interior insulation involves installing insulation between the wall studs or applying rigid foam panels or spray foam.

Vapor Barrier Installation

In areas with high moisture levels, installing a vapor barrier in conjunction with the insulation is essential. This barrier prevents moisture from passing through the walls, reducing the risk of mold and mildew.

Ceiling Insulation

Insulating the basement ceiling is important for both energy efficiency and noise reduction, especially if the basement is unfinished. This typically involves adding insulation between the ceiling joists.

Sealing Air Leaks

To maximize the effectiveness of the insulation, it’s important to seal any air leaks around windows, doors and utility cutouts. This ensures that the insulated space is as airtight as possible, preventing drafts and energy loss.

Maintenance Tips for Basement Insulation

Once your basement is insulated, maintenance is easy, but necessary to make sure you’re getting the full benefits of the insulation.

Perform Regular Inspections

To ensure the ongoing effectiveness of your basement insulation, it’s important to conduct ongoing inspections. Look for signs of moisture, mold or deterioration in the insulation materials. This is especially important after a large amount of rain, or if you’ve had basement moisture issues in the past.

Check for Proper Ventilation

Even with insulation, proper ventilation in the basement is crucial. This helps prevent the buildup of moisture and maintains good air quality.

Address Repairs Promptly

If any issues are found during inspections, such as leaks or damage to the insulation, it’s important to address these problems promptly. This helps maintain the effectiveness and longevity of the insulation.
