Keep Your Bellingham Home Warm, Efficient, and Comfortable with Proper Insulation
Winters in Bellingham can be long, wet, and chilly—and if your home always feels cold, even with the heat running, your insulation might be the reason why. Over time, attic and crawl space insulation can break down, get damaged by moisture or pests, or simply stop doing its job. That’s where we come in.
At Classic Pest Control & Insulation, we help Bellingham homeowners stay warm and save money with proper insulation. A well-insulated home holds heat better, which means your heater doesn’t have to work as hard—and that can lead to lower energy bills and a longer-lasting heating system.

Then our experienced team will install high-quality insulation that’s built to handle the damp Pacific Northwest weather.

1. How do I know if my insulation needs to be replaced?
If your home feels drafty, your energy bills are rising, or your attic or crawlspace has signs of moisture or pest damage, your insulation may no longer be doing its job. Insulation can degrade over time or become contaminated by rodents and moisture. At Classic Pest Control & Insulation, we provide a full inspection to assess the condition of your insulation and give honest recommendations on whether your insulation simply needs repaired or should be replaced.
2. What areas of the home do you insulate?
We specialize in insulating attics and crawlspaces—the most common areas where energy loss happens and where pests often cause damage. Our team removes old or contaminated insulation, sanitizes the area, and installs high-quality insulation designed for the Pacific Northwest climate, improving your home’s comfort and efficiency.
3. Can you remove insulation that’s been damaged by pests?
Absolutely. In fact, this is one of our specialties. Rodents and other pests often nest in insulation, leaving behind waste and causing health and odor issues. We safely remove contaminated insulation, clean and deodorize the space, seal entry points to prevent re-entry, and install fresh insulation that restores your home’s safety and energy efficiency.
4. How does new insulation help save on energy bills?
Proper insulation helps your home maintain a consistent indoor temperature, which means your heating and cooling systems don’t have to work as hard during extreme Bellingham seasons. This leads to lower energy usage and reduced utility bills. Classic Pest Control & Insulation installs materials that are both energy-efficient and durable, giving you long-term savings and year-round comfort.
