I was very impressed with Osaz. When he attended my residence he explained his sealing process and products. I told him of my future plans for the driveway, and we agreed on what was needed. He never over-sold, or coerced me to do more. Osaz and his trainee arrived to begin the work on time. I stood nearby to watch the process. I noticed that his mannerism and behaviour never changed from our initial meeting, even when having to deal with an equipment issue, a new worker, or questions from me. The work was completed in a timely fashion, exactly as he had originally explained it. The 34 year old driveway has had a number of coats of sealant, but this one was by far the best. I will not hesitate to call him again.
