Before & After



Problem: The basement had old crumbling walls that enabled water to seep in and pool on the floor. Basement has typically 2 inches of water with major rain.
Basement had issues of mold and damp smells.

Solution: Zavza Seal team grinded the walls to remove old plaster and paint and applied waterproofing cement in order to waterproof the walls and steps, ensure the structure is watertight, and solve the basement waterproofing problem.

Annette Casatelli

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.


Noemi Herles

Our experience with Savza 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.


Ellen Szuchmacher

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.


Michael Rutigliano

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.
