How Can We Help?

Crawl Space Repair

To maintain and improve the structural integrity of your Bellingham area home, you need to effectively keep damaging humidity out of your crawl space. The ground cover, or vapor barrier, over the dirt beneath your property plays a huge role in this.

Excess moisture will lead to wood rot and the growth of mold and mildew, leading to unhealthy contaminants that can be drawn into your home’s air through your ductwork and other mechanical components leading into your home. With appropriate ground cover and crawl space repair, you can keep out harmful pooling water as well as rodent debris that could lead to unhealthy odors.

Air Sealing

Anything that penetrates the subfloor of your Bellingham area home as the potential to introduce "bad air" into it. This includes register boots, plumbing connections, electrical and communication wires, and of course your ductwork.

Air sealing is recommended by the Department of Energy for most homes, due to common building standards and the low-cost improvement value it adds to your property.

Common Household Air Leaks:

A: Behind Knee Walls

B: Attic Hatch

C: Wiring Holes

D: Plumbing Vents

E: Open Soffits

F: Can Lights

G: Furnace Flue/Chaseway

H: Rim Joists/Seal Plates

I: Windows & Doors


If you truly want to make a huge impact on the comfort and health of your home, consider adding or replacing insulation. You’ll benefit from the well-known energy efficiency gains this can offer, such as improved HVAC performance.

Combined with proper air sealing to prevent the infiltration of fiberglass, proper insulation will greatly benefit those living in the home. But compromised insulation and compromised attic and crawl spaces are often a home for rodents and pests whose presence can leave unhealthy evidence behind, so it’s important to have any existing insulation checked, and removed and replaced when necessary. Doing so will help you avoid nasty indoor air quality problems.

Rodent/Pest Control

Odor from rodent urine or even dead rodents is often the most common sign that Bellingham homeowners have a rodent or pest problem with their attic or crawl space. This odor is typically introduced from leaky ductwork and an unsealed subfloor.

The first job our Home Performance Technicians have is to remove and clean up rodents and their debris, then to replace damaged materials. We’ll also plug possible pathways that rodents can find in your crawl space and look at what could be attracting them, such as the smell of food and warmth. Allow our team to help you eliminate your rodent problem, economically, to improve the health of your household!
