"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."

"Had Groundworks install a drainage system and sump pump in our home’s crawl space. Anthony and his crew, Jordon, Uriel, and James were Outstanding. It was a three day job. They were on time every day and worked their tails off each day. It was a muddy job in cramped quarters. They never complained. Anthony kept me updated on the progress they made each day. Anthony shared pictures of the job as it progressed. They cleaned up the job site each day. Anthony went over all the details at the completion of the job and answered all of my questions. The whole process was Great. From the initial inspection done by Kristy to the office staff and the installation. The communication was also Great. I highly recommend Groundworks for a complete and thorough job."

"Dylan from Harts Services was prompt, professional and courteous... he scoped out three unfinished basement floor drains to determine why they weren't draining properly... he even invited me to observe the process which I did... Dylan was able to diagnose the problem and provide me with viable solutions and costs and within a short period of time emailed me that information to make an informed decision... quite pleased with the service and would/will not hesitate to engage Harts Services again"

Basement Waterproofing questions, answered by experts

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

Interlocking garage tiles made with PVC are the most effective for garages with past issues of humidity and flooding because damp concrete is not suitable for paint. Epoxy coating is also water-resistant and can prevent mold buildup. Finally, porcelain tiles are a wonderful option for wet conditions if your budget allows.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
