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.

Terrific in all aspects from evaluation, to proposal through contract. They were thorough in determining what was required & had to be done to fix the long standing waterproofing problems. They proposed different solutions to the various problem areas. They were responsive to questions & any matters raised. Once I was comfortable with the work to be performed & the estimate work was immediately scheduled. Workers arrived as scheduled & knew what was required. They were courteous, professional & knowledgeable. The crew completed the work timely & left the job clean & in good order. Zavza is an honest, reliable & trustworthy company who knows their business & effectively performs their trade. I believe once & for all my waterproofing issues have been effectively addressed.

The crew did a great job for us! They worked very hard even though the temperatures were in the 90's for the first 2 days of the job. I would definitely recommend them to others.

We couldnâ t be happier with the job that Austin did spraying foam to insulate our basementâ s rim joists (where the top of the foundation meets the wood framing). He measured the rate of air exchange before and after, and it was reduced from more than 10 times an hour to 5.6 times, a significant reduction that will result in future energy savings. Weâ re just sorry we didnâ t do this sooner. Zavza Sealâ s pricing was competitive with that of two others. Austin also identified and measured another source of wasted energy that we may address in the future.

We would like to give a 5 star rating to Austin. He is an asset to your company and should be recognized as such. His personality and work ethic are his greatest strengths. He also knows how to work with others which is another reason he should get an additional 5 star also, his crew were amazing workers and all were very nice. We would have no problem recommending them all to our friends and family. Thank you, Nick and Bernadette
