SaniDry Sedona is the world's most efficient, high-performance dehumidifier and filtration system and is a crucial element in basement waterproofing and crawl space repair.

"I was very impressed with Seth and his crew! We had a horrible water situation in our basement (bought an older home and the first heavy rain revealed serious water issues! ugh!) and knew it needed a serious solution if we wanted to be able to use our basement for storage. Seth provided a free quote and even suggested additional solutions with pricing options. He communicated with me quickly by text and took the time to explain every step of the process. At the end of each work day, he would walk me through all the work that had been done that day (again, answering any of my questions). The guys worked hard for four days, in some pretty hot and humid conditions! Seth also pointed out some other problem areas in my basement as they did their work and made recommendations on how to resolve those issues (there was some wood rot on the stairway area and a leaking water bib; he even gave me the name of a contractor for replacing my rain gutters outside when I was ready). Seth installed a basement dry system along all four walls of the basement, two sump pumps in opposite corners, and a lateral across the middle of the basement. I chose Better Basements & Beyond because it is a local company (not some big box company just out to make a buck) but also because Seth actually does the work himself (again, no fancy representative doing a sales pitch who doesn't get his hands dirty). He stands by his work and makes sure it it done to the highest standards. I would HIGHLY recommend this company to anyone who needs water mitigation services."

"It has now been a year since we had the waterproofing of our basement waterproofed. I waited this long because with this type of repair I believe you have to wait and see if it did what it was supposed to do. Of course we have had a very dry summer but we have had several heavy rains when it did rain. Please note that the customer service is rated very low: this is only because I have no idea what it is like and no reflection on the actual company in that respect. So hear is what I think: First and for most our basement has stayed dry. However, we had a footer that they replaced all around the base of the walls. We did everything we were told to do and yet there are still numerous cracks in it. My concern is that these cracks will allow the concrete to break. We paid $20000.00 for this fix and now have cracks. Was it worth it? Well we are dry so that's good, but for the money I am very disappointed to see all the cracks! This survey gave me no way to give the answer for post work so all I can go on is pre. The flaw in this is that I can only comment on when they were trying to sell the product to me. I found the salesmen was somewhat arrogant and pushy. We went with this company because we only had 1 other prospect (who we would have gone with, by the way, but despite what the salesman from Mid Atlantic would have you believe, offered the same warranty but wasn't able to get to us in time and we needed the work done)."

Basement Waterproofing FAQs, answered by experts

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

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. 

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.
