I had a major problem with failed sealer as well as faded pavers on my 10 year old circular driveway. The pavers were white and looked horrible. I hired multiple companies to fix this issue to no avail, though spending thousands of dollars. I thought I would have to replace my pavers at a cost that exceeded 20k. I then stumbled upon Kenny Kline and his company National Sealing Company. I spoke to him over the phone and he had a thorough understanding of the issues. His company used a water pressure blaster(capable of 40k psi) to clean my pavers. This thoroughly removed all traces of the failed sealer and did not damage the pavers. They then sealed and dyed the pavers. The color match was perfect. This dyeing process is not like paint or stain, and the pavers have a natural look. They literally look brand new. This is no hype. The price was very reasonable. I cannot say enough good things regarding this company, and they are worth every penny I paid them plus more! Thanks again Kenny!!
