"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."

"My daughter is getting married this week and we have a house full of guests from out of town. It would not be a very good time to also have to deal with a flood. The technician just left. He was pleasant and clearly knew his business. He did a professional job of cleaning out the sludge, showing me the workings of the system and letting me know realistic expectations on the motor life. That said, I decided to err on the side of caution and replace the motor which he had with him. He finished up and cleaned up everything – then last we walked outside to be sure the ejection area was in order. I can rest assured that what was a panic situation just a short time ago is dealt with."

FAQs for basement waterproofing projects in Larchmont, 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.
