Great service. After a week of going “round and round” about what type of sealer and what company to hire to seal our new travertine paver patio/pool deck we decided to hire National Sealing. I normally spend a lot of time researching companies and products before purchasing and this was no exception. I’m a DIY guy and after reviewing and researching sealing travertine I decided to hire National Sealing and was not disappointed. I decided not to DIY this project because many things can go wrong. Many stories of the wrong type of sealer, the wrong mixture, applying it in too high temperature, too high humidity etc. There are too many variables in play to go wrong. So many that you need to hire a professional who knows what they are doing. Call Kenny, he can give you the correct information to help you decide. Our pool deck is now beautiful and non- skid. I don’t have to be concerned of my kids slipping or, God forbid, someone else slipping and getting hurt. Do your research, then call Kenny. I’m sure you won’t be disappointed.
