Get matched with top water treatment pros in Rockville, MD

"Enjoying our new water treatment system. Our old one was leaking. Now we have a new stainless steel system in our basement. Our salesman, Scott, was very friendly and helpful. I would recommend this company to anyone who us interested in a water treatment system."

"This job was finished about 2 years ago, I didn’t realize I hadn’t rated them! Hague Water was professional, on time, and the job completed as agreed. We have had no issues with our system, and LOVE the results!"

"They replaced my leaking Poly water line from the street to the house with a new copper line. They tried to pull the new line through but were unsuccessful so they eventually had to trench through my yard to install the new copper line. In order to do this, they did have to cut through my concrete driveway which I had to get patched. After some adjustments were made with the new water pressure valve the system works great."

"We got a quote from leaf home water solutions, Frank was our sales person, he was very nice and personable. We decided to buy the system. We have well water. We had hard water. We were sold only what we needed! Nothing else! Our installer was Andy and he was also very nice and cared about the work he was doing! He made sure everything was level and did a wonderful job! Thank you guys! We are very happy and our water tastes good."

"Very knowledgable and professional. Tech took the time to explain how the system works."

"Remodeling work cause leakages in the gas lines. I made an appointment with the scheduler BUT Michael Bonsby called me to understand the problem and to explain/assure me that they would ensure a thorough check on the gas line/safety. Mark the specialist spent a good couple hours going through every corner of the gas/water lines and sent me a written report. And he spent time explaining the technical aspects so now I know how to maintain the system. Strongly recommend them for service. Good value to price. Peace of mind!"

"They were up front with what is wrong. Provided explanation of the quote. Asked permission to get access to places. They explain the reasoning for the cost and the risks if ignored. Pricing was fair. Went above an beyond to solve the water heater issue we had. Even calling in an electrician to help with a fix. They were on-time to early on their scheduled appointments. Excellent customer service."
