Contacted Hydrohelp911 due to water in basement against the back foundation wall. Was visited by Clint Weimann. Clint saw the issue and proceeded to do a very thorough inspection of the entire basement and exterior of the house. He determined the integrity of the foundation wall and drew up 3 proposals based on his findings. He was incredibly knowledgeable and professional taking time to explain and show me how he determined the inspection results and his recommendations. Clint’s communication ahead of the visit was great as well. Excellent experience. Plan to go forward with repairs using Hydrohelp911.Posted on Google
