"My sewage ejector pump in basement would not stop running and I was looking to replace it. I texted Dean two pictures of the pump, he was able to give me a quote over text and the price was quite reasonable. He received a new pump on 5/22/2023 and came over to my house. After opening up the old pump and checking, he told me that the only thing that is really broken is the check valve, the switch got stuck but is still functioning, and the pump itself works fine. I ended up asking him to only replace the check valve and the switch and this saved me about $1000 from the original plan. I appreciate Dean's honesty, professionalism, and a job well done."

"The visit to my home in West Hartford was a nice affair. The technician explained everything. He even mentioned that I had to get a plumber to remove the sink away from the wall, so the work could be done to repair the window and wall area, but I did not hear him mention that I had to pull permits. The problem with this permit pulling issue is that I never initiated the pulling of permits, and this also is a red flag for me. The pulling of a permit should always be done by the contractor who is doing the job. It ensures that the permit pulled is to code. It ensures that the permit pulled follows local ordinance and CT. laws and statutes regarding construction, and that also includes consumer protection mandates in the State of Connecticut. Having me pull the permit to allow the CT. Basement Systems to do the work is a big, red flag, and it can result in my home owner's policy being cancelled if the permits are pulled either after the fact, or the permits pulled do not line up with the inspection process. I can also be fined by the town for pulling permits after the fact too. I've had my furnace replaced. The plumbing company who replaced the furnace followed state law and guidelines. Especially, since funding provided through a loan from a Credit Union chosen by the State of Connecticut ensured that permits were pulled correctly, legally. The same applies to my roof being replaced. The roofing company pulled the permit. Having a customer whom you are charging in excess of $20,000 to pull a permit is putting that customer in legal jeopardy, which is unacceptable. If I sell my house, and I had the work done in my basement, and the permits were pulled by me. The person who bought my house could sue me for an incorrectly pulled permit. How would I answer questions from the town about the technical aspects of the job, which should be handled by the contractor directly? Why introduce another layer of bureaucracy that slows down communication? Have the contractor pull the permit, so that the contractor and the municipality, town or city can communicate directly, and the pulling of the permit is done correctly and legally. How would I know, when the town should be doing an inspection during or while the job is being completed or after the job is completed? This should never be a requirement of the customer to pull the permit for a job to be done. The tech who visited my home mentioned that I had to hire a plumber to move a basement sink, but they did not mention about pulling of permits, but I went and re-read the quote again, and it is at the bottom of the quote page under "Customer Will" that states not only hiring of the plumber but also pulling permits and scheduling inspections. I did not have this job financed by CT. Basement Systems. I, instead, decided to get a home equity loan. If I did not get the home equity loan, then decided to go with CT. Basement Systems financing, then I would be screwed. The best thing I did was slow the process down, seek my own financing, and ask larger, bigger, deeper questions that prevented me from making a mistake by allowing this work to be done."

FAQs for basement waterproofing projects in Mount Vernon, 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.
