Just Bought a New House?

Moving into a new home is an exciting time. However, it’s also an anxiety-inducing time for some homeowners as they evaluate what needs to be done to ensure an energy-efficient, comfortable home for their families. We’ve put together a guide here to help you evaluate your home’s insulation and whether you need to hire an insulation service provider.

High Energy Costs? Start With Insulation

If you find that your new home is costing you more than you think it should in monthly utility bills, you should evaluate your home’s insulation. Proper insulation can help reduce energy costs by as much as 50 percent in some homes. Here are a few things to check in your new home to decipher whether it’s time for new or improved insulation.

Check Each Room For Temperature Changes

In a properly insulated home, each room should be at the same temperature as the rest of the house. If you find that some rooms seem warmer or colder than others, it’s time to evaluate your insulation. Additionally, if you feel any air flowing through the walls, it’s likely time to replace the insulation.

Check for Drafts

Take time to inspect the home for any drafts. Pay attention to areas close to windows and doors. In particularly drafty rooms, you should inspect the attic and wall insulation. It may be time to replace the insulation in those areas.

Analyze Utility Bills

If your new home’s energy costs are higher than expected, you should analyze your utility bills. If your HVAC system is working extra hard on hot or cold days, it could be your insulation. For homeowners who want a deeper understanding of your home’s energy use, you can invest in a home energy monitor system. Most home energy monitor systems need professional installation by a licensed electrician, but they provide valuable insight for homeowners. Many home energy monitor systems pair with smartphone apps and can detect changes in energy use to the point you can tell when one of your kids gets home from school!

Determine Your Insulation’s Age

Insulation, just like any other homebuilding material, has a lifespan. If your new home was built more than twenty years ago, it might be time to replace the insulation with a newer, more efficient type of insulation.

Find and Seal Air Leaks

Make sure to find and seal any air leaks in the home, particularly around doors and windows. Ensure that any weathering strips are in good condition. Any worn or torn weatherstripping should be replaced as soon as possible to prevent heat loss.


Time For New Insulation?

If you’ve determined it’s time for new insulation, the decisions don’t stop there. There are multiple different types of insulation. We’ve put together this little summary guide to introduce you to different insulation types and both their advantages and their disadvantages.

Types of Insulation

There are multiple different types of insulation, including:

1. Batts and Blankets

Batts and blankets are some of the most common types of insulation because they are manufactured to fit between standard studs and joists. This type of insulation is most commonly made from fiberglass or rock wool.

2. Loose-Fill Insulation

Loose-fill insulation is blown into homes using pneumatic equipment. It is typically made from fiberglass or cellulose.

3. Spray Foam Insulation

Spray foam insulation is made from polyurethane. When the foam is sprayed into a home, it expands to fill every crevice. This process creates a tight seal.

What is R-Value?

The R-value of insulation refers to its thermal resistance. The higher the insulation’s R-value, the better it is at keeping the home insulated. For homeowners here in Longview, WA, you’ll need insulation that is suited for Zone 4 of the United States. You need to look for insulation with an R-value of at least 25 for floor and crawlspace insulation, 38 for the attic, and 19 for the walls.

How To Choose Between Replacing Insulation and Adding Insulation

If you’re deciding between replacing your home’s insulation and adding more insulation to the existing layers, use this guide:

Replace Your Insulation

You should replace your insulation completely if you notice any of the following issues:

  • Mold. If you notice mold or mildew in your insulation, it’s time to replace it. Inhaling mold and mildew has adverse health effects. To avoid mold growth in the future, consider using fiberglass insulation as it is mold-resistant.
  • Pests. If pests have found their way into your insulation, you need to hire a pest control technician and an insulation service. You’ll need to eradicate the pests and replace the insulation to avoid long-term issues.
  • Outdated Materials. If you find that your insulation is significantly outdated, it’s time to replace the insulation. Some older homes use wool or cotton for insulation, materials which are prone to decay.

Add Insulation

You may be able to add insulation to your home’s existing layers. Here are a few indications that it’s safe to do so instead of replacing the insulation:

  • Insulation isn’t thick enough. If you’re worried about your home’s insulation, it’s possible that the R-value of your current insulation isn’t at a level recommended for efficient insulation. In that case, you may be able to add insulation to ensure the house is as efficient as possible.
  • Insulation is compacted. Over time, certain insulation materials will settle and compact. In this case, your insulation service provider will add more insulation to your home to maximize its efficiency.
