"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!"

Basement Waterproofing FAQs, answered by experts

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

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.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.
