Why You Should Install or Replace Your Home’s Insulation
Here at Northwest Crawl Space Services, we find that the most common reason is animal damage to the insulation.
Rats, mice, raccoons, and possums are common animals in our state. They like to use insulation to warm up and nest in it, causing significant damage and filling it with bacteria. This can happen in your crawl space, or even inside your walls.
- Old material that is not up to new codes or has excess wear and tear
- Poorly installed insulation reduces its efficiency
- Water and moisture damage to the insulation
- Missing insulation from the original construction
- Animal damage to the insulation

Air Seal for Your Home
To maximize the energy efficiency of the insulation project, gaps that leak air must be eliminated before the new insulation is installed. Northwest Crawl Space Services performs an air seal service as part of every attic or crawl space insulation project.
In this service, we look for any penetrations in the ceiling or floor where plumbing, ducting, or electrical goes through and seal them to prevent air leaks.
If you notice high energy bills, difficulty keeping your house warm or cool, rodents in crawl spaces, or believe your insulation needs to be updated, call Northwest Crawl Space Services.
Our experts will perform a full inspection and provide an energy-efficient solution that is perfect for your home!

Lior’s crew was on time, quick, polite and efficient. They did a great job cleaning out the crawlspace, adding new insulation and vapor barrier, and sealing rodent points of entry. The crew was in and out in one day, plus they left no mess for me to clean up. Lior came back and inspected the work, and he (or his team) will re-inspect every three months for a year to ensure there are no more animals and the work is still good.
I would highly recommend NW Crawl Space Services for your crawl space and attic needs. I will definitely be using them in the future.

What are the differences between blow-in and batt insulation?
Blow-in insulation and batt insulation are two common types of insulation used in buildings, each with its own set of advantages and applications.
Blow-in insulation, also known as loose-fill insulation, consists of small particles of fiber, foam, or other materials. It is applied using a blowing machine, making it ideal for insulating areas with irregular shapes or hard-to-reach spaces such as attics or walls with obstructions. This method provides better coverage in difficult-to-access areas and can be more effective at reducing air leakage.
On the other hand, batt insulation is composed of pre-cut panels or rolls made from materials like fiberglass or rock wool. These panels are installed by fitting them between studs, joists, or rafters. Batt insulation is more straightforward to install and is commonly used in standard wall cavities and attics with ample space.
Ultimately, the choice between blow-in and batt insulation depends on factors such as the specific requirements of the project, the structure of the building, and budget considerations. Both types of insulation have their advantages and are suitable for different applications.
