"I contacted a few companies for quotes and Insulation Co was local to Edmonds, so I engaged them. Jo provided a fast quote over email, which I found odd as the other guys made an effort to come out and view the job and obviously high pressure sell you.... The quote was inline and lower than other guys, so based on that and the great reviews they had, I went with it. Other companies had as many 1 star reviews as 5 star and that was a deal breaker. Jo has almost all 5 Star reviews...The team was able to schedule a time within a week and did all the work while we were out of town. I'm very happy with the results. Did a crawl space insulation, vapor barrier, all the AC duct work and even the adjoining wall to the basement, which I didn't expect. Were in and out in half a day, all cleaned up and professional. House floors are noticeably warmer. Highly recommend this local small business."

"Greg and his team were wonderful to work with from the start. It's going to improve our house and our life to stop having water in the basement everytime it rains. We can finish our basement and actually use the space now! Thanks for being so easy to work with and delivering a quality drain system."

"All dealings with this company exceeded my expectations from the professionalism of the estimator and installation crew to the communications from the office. Each visit was preceded by a reminder email complete with pictures of who to expect. The installation itself took all day and the crew did an excellent job of completing the panel move from the main floor to the basement. They cleaned up all their work areas and took time to walk us through all the changes and the upcoming inspection process."

"This retaining wall was done during last April and it took a full week to complete. Even with some of the days having some rainy weather, the guys kept at it and did finish this wall well done. I had some weed prevent fabric put down on top of the back fill, and then I chose gravel which I like and have no grass to water and mow. So yes this project ended up with good function and looks, thanks."

"We had Tim and Eli of Reach Dirt Works out to do a variety of projects on our 5 acres. They cut in a 400’ French drain system, removed a small hill and prepped our back yard/patio for sod, prepped and built a 100’ retaining wall 5’ tall, pulled stumps, took down trees and processed them, demoed concrete and installed drainage from the house. I was very impressed with their range of skills. In my opinion, when most contractors can accomplish similar tasks for the consumer, I find that the personal quality of the worker/owners is what matters most, and in this case Tim and Eli are above the rest. I would happily use them again and recommend them to all."

Basement Waterproofing questions, answered by experts

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.
