With Jake's Design and Jeremy's remarkable crew, who were able to efficiently perform the many tasks needed to fix the problem, I now have a dry, clean and healthier crawl space under my home. Thanks to John's superb 5 star Company! Virginia Rossman"

"Ethereal Elements provided exceptional, professional and quality work repairing my basement wall leak. Dealing with Q was very easy, he is personable and to the point. Dale, who performed the work knew exactly what he was doing, he was quality oriented from start to finish. The work was completed on 4 October, I held off writing this feedback in hopes we would have a couple of extreme downpours so I could verify the basement would not leak. Q guaranteed the basement would not leak again, or they would come out and fix it. The cost of this job was reasonable and I was able to use the discount coupon. I would hire Ethereal Elements again."

Basement Waterproofing questions, answered by experts

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

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. 

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.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.
