"From the first visit to my home from Sean for an estimate, to the crew that arrived to do the project I was impressed. Everyone was extremely professional. The crew arrived on time, the crew leader introduced me to the rest of the crew and explained how they would proceed with the project. They protected the work spaces with plastic from my garage to the crawl space opening in side my closet. They went to work and kept me informed about the progress. The whole crew worked very efficiently and got the project done in one day. They left work area spotless when they were done. I would highly recommend this company for any waterproofing project!!"

"Friends who know what our basement looked like before are flabbergasted. The information they send you after you contact them is super educational and everyone was prompt, polite, and professional. Wish we'd done this sooner."

"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."

"They came up with a list of things needed to be completed. I have decided not to have anything completed at the moment. He was professional and prompt for our appointment. Everything went very well. I would probably consider using them in the future. There was a leak in the toilet in the master bedroom. He ended up actually making it worse. My husband was able to fix this problem himself."

"They did an inspection of the attic, and basement.  Determined the possibility of mice in the attic.  Set traps and returned a week later. Offered a year long extermination package that included patching access holes etc... set more traps and 2 other employees removed mice the following week.  We we probably most disappointed in the lack of professionalism.  We provided the ladder so they could gain access into the attic.  On the follow-up visit employee didn't use a ladder and simply pulled himself into the attic. The mice seem to be gone.  We haven't purchased the program.  Very pleasant communication with the office in arranging the appointment.  It was offered as a $99 coupon which was a reasonable price.  We considered the package but decided to wait to see if we still had an issue.

Basement Waterproofing questions, answered by experts

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

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.

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.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.
