CULVERTS, CULVERTS AND MORE CULVERTS
If you are reading this, you have property near Tyler TX with a drainage issue and are considering what can be done to divert water where you want it and away from where you do not. We can help. There was an old joke referencing a commercial where the man speaking said "I am not only the president, I'm also a client". Well... That's the case with me. I got into culverts because we needed them and I was appalled at the estimates I received. It wasn't just pricing that turned me off. It was a lack of professionalism as well. It seemed suddenly everyone could install culverts, from fence companies to handyman outfits. I often felt like I was putting people out just to get a bid on the work in the first place. Then, after waiting several days for a quote, I was provided an estimate that lacked detail, failed to provide specific information and was basically just a dollar amount. I wasn't sure what I would be paying for. If any of this sounds familiar, please check out our services below. - Norman Ward, Owner TNT Tyler
