"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place!

For over 66 years, '58 Foundations & Waterproofing has provided the highest-quality basement waterproofing, crawl space encapsulation, foundation repair, and mold removal. 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 upholding the values upon which '58 Foundations & Waterproofing was built: trust, teamwork, integrity, respect, and communication. From the initial call to job completion, our customers are met with knowledgeable, caring, and professional staff prepared to offer a five-star experience that is unmatched in the home repair industry. What’s more, you can enjoy the peace of mind that comes with our lifetime warranty and our industry-unique money-back guarantee!

"If you’re considering 58 Foundations, do yourself a favor and stop right now. I cannot, in good conscience, recommend this company to anyone. Their complete disregard for accountability is infuriating. At first, things appeared to go smoothly, but the illusion of competence quickly disintegrated when it came time for the building inspection. The city inspector requires a letter from the project engineer verifying that the work is safe, sound, and compliant with code. 58 Foundations flat-out refuses to provide this basic validation of their work. Why won’t they stand behind their project? Are they hiding shoddy, substandard work? As a homeowner, I’m now saddled with the mess of an open permit and no resolution in sight. This is unacceptable. If a company won’t back their work with a simple letter, what does that say about their integrity—or lack thereof? Didn't expect this kind of run around from a well established professional firm, save yourself the headache."

"I hired JES to install a trench and sump system into the basement of a new house I purchased. After the job was completed, I noticed the cellar stairwell was pooling water. They returned and said that they didn't think that the drain was run direct to the sump as it should have been but they needed to open the concrete to verify. I also asked why there was no water in the sumps. They ran tests with water for 2 hours and didn't see water and tried to explain to me that it was expected since the water was running out around the drainage under the foundation. They even had a supervisor try to explain to me over the phone when I questioned it. It took them several weeks to return to fix the cellar drain and sure enough, the pipe was just run to under the foundation and not directed into the trench/sump. A repair team came out and busted up the concrete to correct it. In doing so, they saw that their trench was also not connected to the sumps at all, which is why I never saw water in the sumps and not the mysterious theory they tried to convince me of weeks prior. This is terrible that there is no inspection of work prior to covering it totally with concrete. Or further, there was no physical test of running water in the system to verify the sump works. The repair team that came out were wonderful and did everything correct. After this, I called 3 times and asked for a manager to call me to discuss this and never received a response. The salesman stopped answering my calls. As a note, after spending $30K on this upgrade to my house, it was in worse risk than prior to JES so if you choose them, be careful."

Basement Waterproofing questions, answered by experts

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

Water damage in your home’s foundation is gradual, often beginning with small cracks that let water seep in. Over time, this weakens the foundation, which then allows in more water, causing significant structural damage. This process can take months or years to destroy your foundation, and the repairs can be very costly. Have your foundation inspected regularly to prevent significant damage.
