The Problem
This Portland, Oregon home had old and deteriorating crawl space insulation that was no longer providing the insulation coverage the home needed. Damaged, missing, or uneven crawl space insulation can allow outside air to enter the home, contribute to cold floors, and make it more difficult to maintain comfortable indoor temperatures.
Because crawl spaces can also be exposed to moisture and air movement, addressing the insulation and air sealing was an important part of improving the home’s overall comfort and energy efficiency.

The Solution
Josh Lowe’s Dr. Energy Saver removed the existing, deteriorating crawl space insulation and replaced it with closed-cell spray foam insulation.
Our team applied closed-cell spray foam to the appropriate crawl space surfaces to create a more continuous insulation and air-sealing layer. Spray foam insulation can help reduce unwanted air leakage while providing insulation in areas where traditional insulation may leave gaps or become damaged over time.
The Results
The crawl space now has a cleaner, more consistent insulation system designed to improve the home’s overall thermal performance.
Closed-cell spray foam insulation can help:
- Reduce air leakage between the crawl space and living areas
- Improve crawl space insulation and thermal performance
- Create a more continuous air-sealing layer
- Provide added resistance to moisture
- Help reduce cold floors caused by unconditioned crawl space air
- Improve overall home comfort and energy efficiency
For homeowners dealing with old crawl space insulation, moisture problems, drafts, or uncomfortable floors, a professional crawl space inspection can help identify where improvements are needed.
Josh Lowe’s Dr. Energy Saver provides crawl space insulation, closed-cell spray foam insulation, crawl space encapsulation, air sealing, waterproofing, and moisture control for homeowners throughout Oregon.
