"This has been the worst company to deal with. 1. They did not submit the request for permits as agreed upon so the project was delayed about 2 months while my house was in total chaos as flooring and furniture was moved to other rooms to prepare for the work they were supposed to do. 3. They tried to blame be for their inefficiencies and I had to fight to get a credit for the cost of the permits. 4. When they finally got the permits 2 months later and opened my walls they determined that they could not do what we had agreed upon. 5. At this point the right thing to do would have been to apologize and compensate me for my time and emotional stress as well as bring my walls back to whole. 6. Instead of doing what was right for the customer money clearly motivated Kyle Ward who convinced me that I would still benefit from the three pump system I believed him to be the expert so I took him at his word. 7. With all the rain we have had in NJ year to date the pump system has yet to turn. Quality 1st even came and opened up the pump after three days of rain and it was bone dry, and I have been totally scammed. 8. When I asked for an itemized bill it took asking 3 times for one to be delivered and it did not present a clear picture of the 10% discount on the original contract. 9. Now that I have finally gotten an itemized bill reflecting the discount 1 month and 10 days after initially requesting it, they have called me every day since for final payment, 10. In the interim I have had to invest an additional amount of money to get it done right."

FAQs for basement waterproofing projects in Greenvale, NY
Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:
Water in your basement, including damp walls or puddles on the floor
Mold spots in your basement
Musty smells or odors
Warped doors or walls
Cracks in walls
Insect issues, such as cockroaches and termites
You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home.
However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
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.
