"It went great. Billy Pearsall came over and fixed the problem the same day I called. Both our bathroom tub and sink never drained well, and now they do. Billy was competent, pleasant, polite, and respectful of our home. I highly recommend Valdel and Billy Pearsall."

"Both jobs went very well. With the caulking, they explained that a leak in the shower water control valve and resulting dripping was making the shower pan and caulk wet, which meant that we had to really dry it out before the caulk could be done properly. The outdoor work was also done quickly and for a very reasonable price. They carefully inspected the areas under the roof once they got the rotted board off to make sure that rot did not extend further in."

"In the last few years, we've been getting huge puddles of water all over our basement floor. Never happened before. Some stretched all the way across the floor. Took hours of work with a shop vac to suck it up and days for the floor to dry. In mid-September, we hired Once & Done Waterproofing. They had the lowest price and specialize in our kind of problem. Work was completed in just one day and very tidily done. Very hard-working crew. But it was a leap of faith waiting to see if that work would be successful. Didn't rain for weeks after the sump pump system was installed beneath our basement floor. Weâ ve now had two really heavy rains. The floor remained bone dry after each of them. A little bit of water still did come in at the base of the outside basement entrance, as expected, but it got no further than the drain they installed in the floor at the door. The real test may not come until next springâ s monsoon season. But so far, so good. Based on preliminary results, I would not hesitate to hire them."

"Suddenly, my basement drain was backing up! A friend tried to unclog it, but to know avail. He thought it might have something to do with the sewer line that ran to the street! Right away, I started seeing dollars signs. So, I went on Angie's list and saw the reviews for HL Bowman. Because they were so highly recommended, I went to their website. Immediately, there was a person named Tiera to chat with. I explained my situation and she asked me a few questions. She told me she would have some one call me. I asked if it would be today because there was sitting water in my basement and I was afraid to even flush a toilet! She said it would definitely be today! Within two minutes of concluding the chat, my phone rang. A very courteous person assured me that he could get someone out there today! It was about 8:30 am and he told me that he could have someone by this afternoon and they would call me before they arrived. Around noon, a young man named Clayton called and said he was on his way. When he arrived, he went to basement and checked out the situation. When he came up he said that he thought the clog was in the pipe along the wall going out to the sewer. He brought in a machine and spent approximately and hour and a half trying to open the clog. He then told me that he had called another person from the company to bring a larger machine. Then, Corey showed up with a huge machine and Clayton left to go to another job. Corey was down there for about another hour and half. The machine was much louder than the first one. I was really worried about the cost and the fact that it was taking so long to open. I pictured having to have my lawn torn up and imagining what that would entail, not to mention the cost. Suddenly, he appeared and I tried to prepare for the worst. He looked at me with a smile on his face and said, "it's open". I was so surprised, I am sure he saw the relief on my face. 'He explained that he had to go out 75 feet to the street, and the that the clog was because of tree roots which he grinded through. I knew this machine was probably more expensive to use than the smaller one. So I braced my self and I asked him what the total charge would be! When he told me, I was shocked as that even included the $70 service fee which included up to 45 minutes to diagnose the problem and give me an estimate. But, because Corey had to bring a bigger machine and stay longer than Clayton had estimated, I was sure it was going to be astronomical. Corey said he would figure it out! When he told me the price I could hardly believe my ears. It was half of what I had anticipated! I was thinking about $1,000- $1200! I can't begin to explain how relieved I was.. I would like to say both Clayton and Corey could not have been nicer. Very mannerly, friendly, and polite. When Corey left, everthing was cleaned up! No sewage anywhere. And another thing that I thought was extraordinary, was how unafraid they were of my two pittbulls. They petted them and Corey even told them to stay when they tried to follow him out the door. LOL! And they, listened! I have found my company should I need any future help. It's good to know that there is someone out there who is professional, knowledgeable, and who charges fair prices. It wasn't cheap, but I believe it could have been a lot higher. Family members also thought the price was good. It started out as a bad day, but I had a smile on my face when Corey left!"

"Blue Wolf came out to install a French drain and sump pump after my basement got water after a major storm. Bob came out and was amazing! He took the time to explain each of the steps in the process ensuring that I understood everything he was going to do and what purpose it served. When it came to pricing, he was honest and fair and broke it down into the different components of the job. He answered some questions that I had when I was unsure of how long I wanted the drain to be. He came out to give me the estimate and even arranged to come out the next day to start the job. He finished the same day! After he finished, he took the time to clean up the basement, sweep, and made sure everything was back in place. I felt comfortable working with him throughout the entire process and would highly recommend him!"
