"The owner is the person who comes to your home. He is prompt, professional, looks at ALL areas that might be the cause of your problem with the right tools. And very important, his fee is fair and connects to the time spent. A really nice person."

"These guys are great! Manny showed up on time for his estimate, gave me a price on the spot, and talked things out with me to make sure that I understood exactly what he was including in the insulation project. He was able to meet my timeline, which was quick, and finish the project on time and as promised. He was very communicative throughout the process and pleasure to deal with. His crew was polite and worked hard. I am VERY satisfied with the crew and the workmanship."

"Joey is by far the most responsive, easy-to-work-with, generous-with-information tradesman I have ever worked with. (This was an attic blow-in insulation project.) He contacted me within an hour from my submitting an estimate request. My skepticism that this might mean he was desperate for work because his work sucks simply melted away when he showed up the next morning. He was professional and informative, and after dealing with a few more contractors afterwards, the choice for me was a no-brainer. He and his worker worked cleanly and efficiently. I watched them work, and I know enough about construction to know that their work was thorough and of high quality. The project took barely half a day from start to finish. Reasonable/competitive rate. Great results (the top floor apartment maintains a decent temperature now). Best money spent in a loooong time. Just do it, people!"

"I hired zavza seal to finish my basement and I am pleased with their work. I have dealt with many contractors over the years, unfortunately these experiences are often full of frustration and stress. Not the case with Zavza seal, they are completely professional and put the customer first. Anderson and his crew were courteous, hard working, and efficient. They came when they said they would and cleaned up everyday. Jake was the project manager for this job, he is an honorable man and very easy to work with. He was onsite every day from the estimate to the finishing touches. There was constant communication, I knew what the plan was each day and he was always very responsive to any questions. I've had other pm's disappear to other jobs, or push me toward doing things in a way that was easiest for them. Jake was very collaborative, and his focus was completing the project to our satisfaction. Midway through the work I asked for a couple of changes that were not in the original estimate (storage room and laundry shelving). Zavza added them in at no extra cost. My house is old and presented challenges with regard to the floor and ceiling joists. The crew took the time to do things the right way without shortcuts. Jake came out and worked a full Saturday and Sunday to ensure that the ceiling was right and the project was finished on time. Not many companies take pride in their work like this these days. It was refreshing to see. My basement is now the nicest room in the house. Zavza Seal went above and beyond and I wholeheartedly recommend them."

Remodels
"In addition to completing the kitchen, which was complete gut (walls included) and Satillo tiles with inserts, We also did the master bedroom/closet, hallway closet, and front door with screen. The storage and shelves for closets were custom built using oak wood (also stained). My house had been one project after another due to heating pipes issue. It was very time consuming and a lot of delays. But Nick stood by us and even taught me a few tricks for my little projects. He is a genuine person and you never have to worry that he won't come back. Hire him, you truly won't regret it. Excellent craftsmanship, efficient, and did I mention my house looks great ð . He is also available for questions and touch ups. He never leaves a job undone (my total project was over 7 months and was not easy) Very patient (with wife mostly lol) . I mean I could really go on and on. Nick is the best."
