The guys at National Sealing were great to work with. Kenny walked us through the options with our challenging pink brick to coordinate them with our newly painted house and color scheme. What I appreciated most was that Kenny was up front and frank about exactly what their dye process could and could not do. I felt like I wasn’t being “sold” but rather informed. His technician came out and Kenny quickly called saying the bricks had too much sealer left on them and to really get a good result and value from what we would spend on the dye process we needed to sandblast. He offered a guy they work with but encouraged me to get other quotes to feel comfortable with the price. His guy came in at the same price as my lowest quote that could do it in the timeframe we needed. Mark (technician) came back the very next day after sandblasting and applied two coats of dye. Mark walked me through the color process and what shade of gray we wanted. It turned out amazing. Highly recommend.
