"I dealt with the owner Paul from start to finish. We had purchased all of the materials for the renovation of our bathroom as well as our master bedroom, halls and entire first floor ceiling. Paul and his crew made our entire plan come alive and completed the project in the time span they had promised. We are thrilled with how well every thing went. We had them do an additional project on the exterior of our house after completion of the interior work and this was handled as well. the few minor problems that occurred were rectified with no delay, and to our complete satisfaction."

"We had Mr. Barillas come power wash our roof and seal it. His guy left a huge mess of roof tiles and roofing particles all over our front and back yard. I called him to have the guy come back. He said he couldn't because he was on to another job and wouldn't be able to come back for two weeks. He also tried to get us to hire him to replace the roof. He sent videos of roof damage. Who knows if the damage was done by his guy during the cleaning! I talked with another roofer and they said that for a roof cleaning company to recommend a new roof is unethical. I did a search for his company and could not find it on the internet. His website is not working and the address on the receipt after searching it out does not show his company. Attached are pictures of the mess left"

FAQs for basement waterproofing projects in Merrick, 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.
