Crawl space insulation in Seattle.

We don’t have to worry too much about freezing temperatures in the Seattle area, but it does get chilly. A lot of crawl spaces have plumbing lines and HVAC systems running through them, so you could be paying more in energy costs if yours isn’t insulated. If you have drafty spots in your home above where the crawl space is, poor or no insulation might be the culprit.

Signs of poor insulation

Even if you know you have insulation in your crawl space, you could still need a replacement. While insulation can last for 10 to 15 years, water damage and other outside factors may decrease its lifespan. These could be symptoms of poor insulation, especially if you experience a few:

• Mold odors
• Pest infestations
• Drafts in the home
• Higher energy bills
• Inconsistent indoor temperature

Fiberglass and mineral wool

At Matvey, our crawl space experts use a variety of high-quality, reliable fiberglass and mineral wool insulation. We can help you decide which option works the best for your unique crawl space during your free inspection.

Fiberglass

The most commonly used insulation, fiberglass is very cost-effective. It has a good R-value and comes in a large range of sizes. We recommend fiberglass in situations where we need to fill odd spaces and large ones, because it is more budget friendly.

Mineral Wool

Mineral wool is typically a higher cost but has a better R-value than fiberglass and is more eco-conscious. This super dense insulation is fire-resistant and hydrophobic – meaning it isn’t as prone to mold growth. However, mineral wool may not be suitable for specific applications since it is not available in as many sizes as fiberglass.
