"I asked for our technician to call me ahead of time, so that I could be home to let him in to do the basement and garage. Our technician, James Nelms was excellent. I was running late and he actually waited about 15 minutes for me to get home. Once there, he did a superb job, explaining what he was using, how it was applied and how long it should take to see the results. I've been using Bulwark now for 2 to 3 years and they are great!"
