"Seamless experience from start to finish. Todd was super knowledgeable and through on the consult/ sales end. The install team made quick work of the project. Their work was top notch and my basement is now completely dry. I would recommend their services to anyone with basement or foundation issues."
Stair-step cracks on your foundation wall are a common sign of foundation problems caused by settlement and soil issues.

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. As a result of its compact size, it occupies less space in a basement and can easily be tucked away in a crawl space. The unit eliminates damp, musty odors by drying and filtering the air, and it costs less to run than other dehumidifiers. It filters mold spores, dust mite droppings, dust and other particles, and it keeps hu
The wall height is measured to cut PowerBrace beam to its length and the bottom of the beam is anchored to the floor. The top bracket is installed and the beam is secured. This patented design can be straightened over time, eliminating future bowing, buckling, or inward tilting movements.

"In response to my initial email inquiry, Eric, the owner, came to the house and we discussed all of the issues and how they would deal with them. He took measurements and pictures and was very professional, polite and encouraging. Within a few days he emailed me a very precise and detailed proposal outlining all three jobs and the estimated cost. I immediately accepted. Adam came to the house and took some more measurements and pictures and said the work would begin the following week and take three days. The required permits were taken care of right away. As scheduled, Paul (the onsite foreman), Lloyd and TJ showed up and began to work. Braces were installed against the basement wall after the cracks were repaired. On the exterior a French drain was put in along the side of the house extending to the ditch out front. The old walkout was excavated and a new permentry door was installed. The work went as planned with no problems and was finished in three days. All debris was taken care of and they cleaned up when they were through. All of my questions and concerns were answered. Adam followed up the day after the work was completed to see if I was satisfied and to answer any additional questions. I also must give kudos to Cynthia, the office manager, who made the paperwork and payment process smooth and effortless. The quality of the work and the quality of the employees is just exceptional.

"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."

"Don't be pressured into having the work done on their schedule. I had way too much "stuff: in my basement, that is now pushed to the center of the basement and even though is was covered with plastic, everything is covered with white dust. As far as the finished drainage work, I'm very pleased."

Basement Waterproofing FAQs, answered by experts

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Typically, waterproofing a basement should last up to 10 years. However, it’s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.
