Testimonials From Bronx, NY

Masoud Sultani
“They just finished the job today we just have to wait for a couple of heavy rain fall before we can close up the walls as Zavza suggested it. I interviewed many contractors for about a month I decided to go with Zavza for many reasons. One first time Jake came by to give estimate I realized how transparent and honest he is. Second Dice from the office was extremely patient with my thousand questions and understood my concerns. Over all the whole crow treated me like part of a family and treated very hard to help me. I have to add I added a couple of things in the middle of the process they were kind about it and did the best they can to meet my concerns.
Valerie Krizel
“I would highly recommend Zavza Seal. The crew manager, Anderson, communicated with us clearly and daily. The crew installed a French drain system and support steel beams in our crawl space. It was a wet, uncomfortable space but the men gave the job a 100% effort. They cleaned up at the end of each day beyond my satisfaction. From start to finish, every aspect of the job was well planned and executed! Thank you to the entire team. You are the best!!!”
Bruce Moshier 
“Anderson,the crew leader, was knowledgeable, thorough and polite. Crew arrived on time every day of the 3 day project. My crawlspace is now sealed and secure exactly as I wanted and as Zavza stated in proposal. I would definitely use Zavza again if needed and recommend to anyone. Thanks again for a great job!!”
