"I waited a few months before posting my review to test the finished product. All I can say is incredible from start to finish to performance! Jordan and Jim are two of the most honest people I have ever met. The estimate process went so smoothly. No pressure, no overselling and scare tactics I had with other large companies. Jordan listened and offered real solutions. In fact they turned out to be over $15K less than the next bidder. Jim who also owns the company and his crew showed up on time. Worked their butts off and explained exactly what and why they were doing certain things.Just another level of transparency. They put in french drains, concrete walls to support the compromised brick ones in the basement. Then two new sump pumps one is a no power required backup, a pump to remove the washing machine water into the sewer line instead of the sump pump. The also wrapped the basement, crawlspace, installed a new crawlspace door. All in two days! The house is so much nicer and dryer. My AC does not run as often, the basement is dry. We used to get water after every rain storm. We have had several heavy downpours and not one single drop of water! I highly recommend them. Fair and honest people!"

They showed up when they said they would and provided a written description of all work to be done. They even planted grass over where they had to dig. Pay for quality work, not tv advertising."

"Overall very good - came out quickly, completed repair the same day and also let me know about some additional issues they found that I was able to fix myself. The price seemed a little high but I don't have a lot to compare it to. I was just glad to get it fixed so quickly."

Basement Waterproofing FAQs, answered by experts

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

Installing storm windows can protect your home’s interior from heavy storms. Most storm windows are made with enamel-coated aluminum with screens and sliding glass panels. They also make your house more energy-efficient. The average storm window cost is $12,000, ranging between $4,250 and $19,850, depending on mounting, window types, glass types, and frame materials.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.
