"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."

"4 hyberheat mistubishi mini splits (2 of them extra powerful) and a great outdoor unit $30k 4 years free financing Far better deal than Blue Flame and others and no sleezy salesman tactics. Service was good too. A broken seal meant water was getting into the basement. They came in 18 minutes and fixed is super fast!"

"They did an excellent job and everything was done on time and with exactness. They work very professionally but they also had fun as they worked. The final price ended up being right on with what the estimated price was. They provided all the materials and they cleaned up when they were finished and didn’t leave a mess behind for us to have to clean up. They listened to us and to what our desires were and then they explained the different options that we had. They were very respectful not only to us but to our property. They showed up on time when they said they would be here and the project was completed when they estimated it would be done. We would definitely recommend them for any plumbing job you have, we will call them for any future needs we have."

Basement Waterproofing questions, answered by experts

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.
