The cement threshold under my sliding doors was broken allowing water to seep behind my stairs and into the basement. I had many people come out and quote. Most were as high as $5000 and included removing my doors and putting in solid limestone. Others said that they would only do the threshold if I paid them to do parging around the house. It was turning into a nightmare, until Kris came out. He did ONLY what had to be done, and he did it well. He reinforced, repoured, and sealed the threshold. He is an honest man.
