"Overall the job went well. From diagrams I received before the job, I expected the pump to be installed in my partial basement since it is lower than the crawl space. Instead it was installed in the crawl space, drawing air from beneath the plastic they installed. I had had an electrician working on the house, and he had run new wiring for the living room but had not yet connected it. The installers chose to use this wire to power the pump. I learned this when the electrician came back and told me they had taken his wire. This was disappointing. The installers left a follow-up test kit and gave verbal instructions to install it two weeks after the installation in a closet for seven days. However, the printed instructions said NOT to install in a closed space such as a closet, but to put it in a central location. Close to the thermostat was said to be best. The instructions also said that the test must be between 3 and 7 days, with 4 days being the optimal. Again, the company seems to be ok, the pricing was $1000 less than one quote and $400 less than another, but the installers' knowledge and experience may vary."

For more than 60 years, ’58 Foundations & Waterproofing has provided the highest-quality basement waterproofing, crawlspace encapsulation, radon mitigation, mold removal and foundation repair solutions for homes and commercial properties. We lead with a promise of Trusted Five-Star Service, which means the customer experience is at the center of everything we do. Since 1958, we have been steadfast in keeping this promise and in upholding the values on which '58 Foundations was built: trust, teamwork, integrity, respect and communication. This comes across in all that we do: from the initial call to job completion, our customers are met with a knowledgeable, caring, and professional staff prepared to offer a five-star experience that is unmatched in the home repair industry.

"I had a very unfortunate experience with a misleading sales rep. In December 2022, a sales rep named Ryan came out to my house to show me my options. He suggested that we have a perimeter trench dug around the basement with a well and sump pump. He went over the options with me and told me about the amazing sump pumps that 58 Foundations & Waterproofing has...they are battery back-up in case of a power outage. I was excited about that because it gave me peace of mind. Let me be clear when I say that there was only a SINGLE option presented when it came to the type of sump pump they provided. Ryan gave me the option of a battery back-up and no other options. The install crew comes out, does a fantastic job, and gets it all done in a timely manner. 5 months passes and we have some bad storms rolling in. I wanted to be sure that the sump pump battery was still good, so I open the lid of the well to check on the battery, only to find out that we have a pump without a battery back-up, like I was told by my sales rep we would have. I reach out to the company to see if the battery is hidden inside the pump. After 24 hours, I still haven't heard back from the company, so I reach out to the sales rep directly. He tells me that I didn't purchase the battery back-up pump and that he would be happy to sell me one for an additional $1,500 (I am sure he would be happy to sell me one). I contacted the company to see what resolution we could arrive at. I have basically been told at this point that I did not purchase one even though the sales rep told me I was getting a battery back-up pump. A battery back-up was VERY important to me. The SC manager for 58 Foundations & Waterproofing called me today and offered to sell me one. But I cannot bring myself to pay for something that I was told would be included. She told me that the invoice does not show a line item for the battery back-up and that the invoice only lists "sump pump". But, how was I supposed to know that "sump pump" didn't mean the battery back-up pump that the sales rep told me would be included? How was I supposed to know that there would be a separate line item for "battery"? They have relied on the ignorance of their customers to take advantage. Everyone who gets one of these systems, make sure that you actually get what your sales rep told you...because I did not. And at the end of the day, of course the company has blamed me for the miscommunication. The SC manager told me that there was just a miscommunication and that she was sorry that I did not understand what I was purchasing. In reality, the reason that I did not understand is because I was misled. Until this issue is fixed and a battery back-up is installed free of charge, I will continue fighting this issue."

"They had to take out a portion of my front wall which was not planned on, and the conic quality of the concrete was not as good as I thought it should be they destroyed the brick wall that they said they would be able to save and I think they also damaged an additional plumbing line, which I’m going to have to have repaired But we did get the leaking stopped, which was the big part of the problem they had to dig up the entire front foundation down to the 8 foot footer and re-waterproof the wall put in a French drain system and a new drainage system for the gutter and a sump pump"

Radon Detection and Reduction questions, answered by experts

Costs depend on property size, test types, and additional services like mold sampling.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Through air sampling devices and surface swabs in key areas of concern.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.
