"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.

"Larry and Glen did work for us - this was the third job. They installed a 40' block retaining wall to extend our back yard. Then they installed a patio and two walks. Once again they did a great job for a fair price. These guys are the greatest."

Basement Waterproofing questions, answered by experts

Yes, you can enclose your crawl space. Enclosing your crawl space can promote energy efficiency and reduce the risks of pests and mold by limiting factors like humidity. It can also reduce heat loss, which is why doing so for the winter can make your home more comfortable.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.
