"David and Cody from John's Waterproofing went straight to work; they quickly found the problem, showed me the problem, discussed what would have to be done to fix the problem, fixed the problem, then thoroughly cleaned up. Very nice people to work with, from the schedulers through the technicians."

"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 was prompt in coming to view what needed to be done and quickly assessed the best way to prevent storm water from entering our garage. He gave me a very fair bid and stuck to it. His work crew, Young and Jasper, were here right on time and worked hard all day until the job was completed. They didn't waste a minute, doing exactly what they said they would do. Their final product was excellent, much better than what I envisioned it would look like. Their work will resolve our problem (now I just have to keep things clean). Thank you for a job well done! I certainly will hire Wu Construction again if I need any services they provide."

"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."

Basement Waterproofing questions, answered by experts

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

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.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.
