The Importance of
Waterproofing Your Basement
Waterproofing is a vital part of the construction process of any building – residential or commercial. Many buildings are designed with materials that easily become porous to water. As a result, these buildings may incur structural damages over an extended period of time.
When planning your building, you want to prevent water leakages from the outside wall and ensure your building is hermetically sealed to any intrusion of water from the basement, the exterior wall envelope, or the roof. Zavza Seal is the foremost waterproofing service provider for residential and commercial properties in Nassau County. Our team of trained experts will develop a detailed estimate for your project and make sure that your home or building stands the test of time.

I received a few quotes to get the walls in my home filled in with blown in insulation. Zavza Seal was affordable and they did an excellent job.
They were very concerned with cleaning up, which I appreciated. I felt the difference in my home immediately. No more freezing cold walls. I recommend them, hands down.
Our experience with Zavza Seal was wonderful and smooth. The crew is well organized. They listen to your plans. They showed out in time. They left everything clean. They did an amazing job! I highly recommend this company.
Efficient, courteous and responsible workers. The job was quoted as being completed in 2 days but more work was required and they returned on the 3rd day and completed the job without additional charges. They reinsulated my crawlspace (not an easy job). I recommend Zavza Seal without reservation.
Couldn’t be more satisfied with the job Zavza Seal did. Brendan and Jake were accommodating, fair and extremely knowledgeable. Their team worked incredibly hard that day under difficult conditions and did a great job. I manage a multi-unit HOA and we will definitely be using them again.
