"Alex, the owner and lead contractor was a pleasure to work with. From start to finish the process was seamless. The waterproofing process was explained as well as the benefits from performing the work. Alex was personable, professional and knowledgeable. The pricing was very fair and competitive with the highest quality of workmanship. "

"When I am having work done on my home, I want folks that are knowledgeable, reliable, and punctual. I had a REALLY good experience with Zavza Seal. They are 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 Quick books). 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 a lot 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 base create (concrete used for pool settings), and sealant. They addressed every single spot I wanted to be 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 its 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 nickeled and dimed. It was always a fair price for the work and materials. I could not ask for better communicators. Before I settled up the final payment I was walked through all the work done, and they understood I wanted to run my 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 base to create and sealant to cure) for me to do that, and I never felt pressured, or questioned as to why I wanted to do that. The basement is dry now, and I have peace of mind! This company 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 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 am confident I will be taken care of if I have any issues. This is incredibly rare these days, and I will be recommending, and using them in the future! Seriously the best experience I have ever had with a contractor."

"These guys were great. I had mold in my basement walls. This company was very knowledgeable and their price was very good. In one day not only was all the mold gone but they also waterproofed my basement. They were professional and fast. I highly recommend them."

"Bobby and his crew answered all my questions, they were respectful and extremely helpful. Bobby and crew went above and beyond what was on the contract. My house looks beautiful, they power washed entire building, pained the sidewall of the building with thorocoat, front of house was pointed where necessary and applied waterproofing sealer, glass block window, painted stoop and stairs, cemented cracks on stoop and sidewalk, painted outside railing and applied cement in basement where needed. I have to say some of what was done wasnâ  t even on the contract, so they went above what was expected and to my surprise Bobby didnâ  t charge extra. Being a single woman who has had bad experiences with contractors and their disgraceful personalities, having Bobby and his crew work on my property was a pleasure and breath of fresh air. I would hire Bobby and his crew again and recommend them in a heart beat. Best work!!"

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."
