Top Rated Foundation Repair, Mold Remediation, Insulation, and Waterproofing Contractors in Addisleigh Park, NY

“Zavza provided an excellent backyard drainage solution for our problem of water leaking into the basement during bad storms. Their work crews were excellent with minimal disruption and good clean up when done. I would recommend them.”

“Zavza Seal provided exceptional service. It's obvious the pride their team takes in the quality of their work and contribution to their reputation for excellence. Additionally, their warranty was unsurpassed by any other vendor I sought estimates from.”

“When I'm having work done at home, I want folks that are knowledgeable, reliable, and punctual. I had a REALLY good experience with Zavza Seal. They're an incredibly well run organization. Before any work is done they provide you with a PDF estimate with photos and detailed descriptions of the work being done. You then receive an invoice (that agrees to that estimate) payable by checking or credit card (via Quickbooks). Their billing department is separate from their workers, and all workers were supervised by a manager who was also responsible for doing the estimate. From the start of the estimate I felt taken care of. Dice their admin was incredibly responsive to all my questions, emails, and texts. Jake the manager of the team was incredibly thorough when overseeing my project, and Andersen (who was doing alot of the project work), was incredibly professional and always took the time to explain to me what they did and what was left to do before they left my home each day. Everyone always showed up on time when they said they would. I had a relatively large project - waterproofing my exterior and then replacing a sinking floor in my porch from old water damage. They tackled outside first to ensure no more water would get into my interior. I was sealed up outside with basecrete (concrete used for pool settings), and sealant. They addressed every single spot I wanted covered, and also sealed up spots I had no idea needed sealing. They worked around my schedule, and it was great that I had a point of contact outside of the day to day workers (Dice their admin) that I could reach out to for scheduling, questions, invoicing etc. I love the fact that these are two separate parts of the business. Each part does their job very well and it makes a great customer experience. My porch floor was a larger project since the beams holding the floor up were rotted and needed strengthening. The floor needed to be ripped up and with that - we went with all new tile. I was talked through every step of the way, and where project costs needed to be increased, it was very transparent and I was always consulted and presented options and reasoning. Every quote for all work done was incredibly reasonable. I never felt gouged or nickled and dimed. It was always a fair price for the work and materials. I couldn't ask for better communicators. Before I settled up final payment I was walked through all the work done, and they totally understood I wanted to run my own water test before paying the balance to ensure all the leaks I was having were settled. This required them to wait 48 hours (for the basecrete and sealant to cure) for me to do that, and I never felt pressured, or questioned as to why I wanted to do that. Basement is dry now, and I have peace of mind! This company really cares about doing good work, standing by that work, and ensuring the customer is satisfied. Every question/concern I had was addressed and answered. I always try to be a good partner to the contractors I hire (being clear and transparent about what I want done, limits to my schedule/budget, honest assessment of the situation, paying on time when work is done, etc), and I really appreciated that Zavza Seal recognized that, and reciprocated it, not all contractors do. The work done on my home came with a 5 year warranty. I hope that I never have to use it, but I know this team stands by their work and I'm confident I'll be taken care of if I have any issues. This is incredibly rare these days, and I will definitely be recommending, and using them in the future! Seriously the best experience I've ever had with a contractor.”
