Marin County is known for its beautiful, historic homes, and if you’re lucky enough to live in one, you know they have a lot of charm. But with age often comes hidden issues, and insulation is one of the most common problems we see in older homes.

At Insulation Solutions, we help homeowners recognize when it’s time for an insulation upgrade in an older home in Marin. If you’ve been noticing drafts, high energy bills, or uneven temperatures, your home could be trying to tell you something. Let’s walk through the key signs that it might be time to re-insulate and why acting sooner rather than later can make a big difference in your comfort, energy savings, and even your home’s long-term health.

 

Why Older Homes Often Need Insulation Upgrades

Many houses built before the 1980s, especially those built before modern energy codes, were not designed with today’s insulation standards in mind. Some had little to no insulation at all, or they used materials that have since degraded or become less effective.

According to the U.S. Department of Energy, adding insulation to older homes is one of the most cost-effective upgrades you can make to improve comfort and energy efficiency. In fact, proper insulation and air sealing can cut heating and cooling costs by an average of 15%.

Marin’s varied climate, from coastal fog to inland heat, puts additional demands on your home’s insulation system. If your home’s insulation is outdated or missing, you’re likely feeling the effects, whether you realize it or not.

 

Signs You Might Need an Insulation Upgrade

1. Uneven Indoor Temperatures

Are some rooms always hotter or colder than others? Insulation’s job is to create a consistent indoor environment. If your living room feels like a sauna but your guest room feels like a walk-in freezer, poor or deteriorated insulation could be the cause.

2. High Energy Bills

If your heating or cooling costs seem unusually high, even when you’re careful about thermostat settings, your home may be leaking energy through under-insulated attics, walls, or crawl spaces.

EnergyStar.gov estimates that homeowners can save up to 20% on heating and cooling costs by upgrading insulation and air sealing.

 

3. Drafts or Cold Floors

Feeling a breeze even when all the windows are closed? Drafts around floors, walls, or ceilings are a telltale sign that insulation isn’t doing its job or might be missing entirely in certain areas like crawl spaces or attics.

 

4. Old or Settled Insulation

Insulation doesn’t last forever. Over time, materials like fiberglass and cellulose can settle, compress, or degrade, losing their ability to resist heat flow.

If your attic insulation looks flattened, crumbly, or dirty, it’s time for a replacement.

 

5. Moisture Problems or Mold

Poor insulation and air leaks can allow moisture to seep into walls and ceilings. This not only damages your home’s structure but can lead to unhealthy mold growth.

If you see signs of water staining, condensation, or mold near exterior walls, upgrading insulation and adding proper vapor barriers can help protect your home.

 

6. Older Home (Built Before 1980)

If your Marin County home was built before 1980 and has never been re-insulated, there’s a good chance you’re missing out on the benefits of modern insulation materials. Even if your home feels comfortable most of the time, upgrading insulation can dramatically improve energy efficiency and indoor air quality.

 

Key Areas to Focus On

When we assess older homes in Marin, we typically recommend focusing on these areas:

  • Attic insulation: The number one area for heat loss and gain.
  • Wall insulation: Particularly important for homes with hollow walls or limited existing insulation.
  • Crawl space or basement insulation: Critical for controlling drafts and moisture.
  • Air sealing: Essential for maximizing the effectiveness of new insulation.

We work with you to customize an insulation upgrade plan based on your home’s design, existing materials, and your personal comfort goals.
