Welcome to the Classic Family: over 25 years experience & a consecutive Angi Super Service award winner! Classic Pest Control & Insulation delivers peace of mind when you need it most. Specializing in Rodents, Insects, Insulation, Crawl space & Attic repair work - We've got you covered. Serving King, Snohomish, Skagit, Island, San Juan, and Whatcom counties in Washington State. Give us a call and let us know how we can help serve you.

"Wow. I have used Classic for 8 years, both for insulation and pest control. They were great to work with and did a consistently good job for a reasonable fee. As a text from them today requested, I called to reschedule a service call. The person who answered identified himself as the owner, and indicated he was “back” because he didn’t like the way the company was being run. Because I wanted my service to include a crawlspace inspection of the rodent traps that they put in - something that is part of the service they have always done — and that I pay for — said I was being too rigid and he didn’t want me as a customer. Again, wow."

I am a self-taught artist, initially drawn to experiment with pastels and colored pencil, and now working with acrylic on canvas. My art speaks for itself.

Basement Waterproofing questions, answered by experts

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.
