"This was the second time I hired zavza seal. This time I needed help with attic insulation for my parents house. Starting with setting up the free appointment, ending with the crew and quality of the work - they deliver a great experience and I highly recommend them for anything waterproofing, insulation, concrete and foundation fixes. If you are looking for a contractor and donâ t know who is trustworthy and professional, go with Zavzaseal, you ll be in a very good hands."

"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!!"

"Called about a basement sewer backup and couldn't be happier with the service. This guy is the doctor of draining — diagnosed the issue fast and had everything flowing again in no time. Professional, honest, and clearly knows what he's doing. Highly recommend, don't hesitate to call him if you're dealing with a drain or sewer issue!""

"I called John and left a voicemail and he got back to me immediately. He double checked that I needed a cesspool certification and not an inspection which would have been more invasive and costly, and once confirmed, scheduled them to come out that weekend. The man who performed the certification was right on time and was very quick but professional and thorough. Everything was seamless, and for something requested by the bank so last minute, we were grateful to get it completed so quickly."
