    My experience with Hague Quality Water of Maryland started in June 2024, and a year later I…read morecompletely regret the $1,395 I spent. I never had issues with their technicians or customer service, but I was sold an Upflow Water Neutralizing System--which I later learned is not typically recommended for well water, even though many companies sell it for that function. My house (built in 1946) has a well, water softener, and pH neutralizer. When the neutralizer failed, I contacted a few companies for estimates, and Hague's price was the best. I assumed they'd know what system my house needed and didn't think twice when they recommended an Upflow unit. The salesperson emphasized that it saved water and electricity since it doesn't backwash--something that sounded good at the time but means little when you're on a well and not paying a water bill. Fast-forward to July 2025: Hague serviced the system and added calcite. Immediately afterward, my water pressure dropped to almost nothing. The technician suspected the calcite had solidified and clogged the tank, recommending it be dumped and a sediment filter added. The problem? A Downflow system backwashes automatically, breaking up buildup and clearing sediment--an Upflow system does not. After getting two second opinions, I learned I could either replace the one-year-old tank with a Downflow system (meaning the $1,395 was wasted) or plan for the tank to be dumped and refilled every year. Another company confirmed that Upflow systems are generally unsuitable for a small household on well water because of this exact issue. It turns out many companies still push Upflow systems since they're cheaper and easier to install, and most customers don't know the difference until problems appear. I wish I'd done the research first--I would have gladly paid a little more for a system that simply needed routine servicing rather than yearly repairs. Hague may be fine for maintenance, but for installations, I strongly recommend looking elsewhere. I read a LOT before writing this, so here is just a sampling of the websites I looked at: Are Upflow Neutralizers Better than Backwash Calcite Neutralizers? (2015). Well-Water-Report.com. https://www.well-water-report.com/2015/06/are-upflow-neutralizers-better-than.html DKH53. (2020, October 27). Upflow vs Downflow acid neutralizer.

    Hague has been responsive and helpful to me in servicing my RO system and water softener system…read more When necessary, HERMINIO brings the supplies needed to maintain my water softener system. Then he fills the tanks and tests the water. BRYNN keeps track of the timing for this maintenance, which is helpful. HERMINIO recently repaired my RO faucet. He could've suggested I purchase a new faucet, but instead he simply replaced the inexpensive part which saved me money. HERMINIO is thorough and efficient, always explaining to me what he's doing and why, and I like that he charges for the time he's here, rather than adding unnecessary minutes that creep into a second hour.

    EXCELLENT communication and service scheduled everything through email and then they reached out to…read moreme via text the day of. I wanted to get an electric anode rod replaced in my water heater since they are supposed to be replaced every 3-5 years but the electric rods last up to 20 years. I didn't want to take off time from work and they booked me for an evening appointment between 6-7 pm on a Friday. The tech showed up right on time and got to work. The procedure is relatively simple but if you run into a snag getting the rod out then it can be time consuming so I didn't want to mess with it. Less than an hour later he was done the cost was $250 which is inline with the range I was seeing online for what people paid with other places. I saw a wasps nest on my front porch as I was paying the invoice with the tech and he went to his truck and got some wasps killer for me to use.

As soon as Mother Nature got herself together, they came out. He even saved my beloved little tree. They showed up on time, and finished the same day. He and his crew were respectful of my property and neighbors. The charge was just perfect for the job that was completed. They even put grass seed down after they finished. I can't say enough about their professionalism, friendly demeanor, and finished product. The Owner's wife Ashley was the cherry on top. She helped with the billing, appointments, and my many questions. I have already referred them to my friends. Thank you Elite for restoring my plumbing, my bathrooms send their love!!!!!

    I initially thought about taking off a star because John arrived outside of my appointment window,…read morea pet peeve of mine, but then I remembered a few things: he came on a Sunday, on less than a day's notice, Arlington is very far from Upper Marlboro, the appointment before me went over, which can happen to anyone, and most importantly, small businesses are the backbone of America. John was very polite and immediately told me my HVAC closet smelled because a mouse died in there. He also called a relative while at my place and on the way home to give me their suggestions on dealing with the smell, which has nothing to do with HVAC and is above and beyond in my opinion. Yes, I did have to pay the $100 fee to come out. I paid in cash to not have to pay the 10% processing fee. I was fine with paying this to have someone come out so quickly, and on a Sunday. Would call again. When my problem actually involves HVAC repair.

The only reason I wouldn't give it five stars is because whomever I booked with didn't properly explain how the pricing worked beforehand which would have influenced my decision to use this company or not. The overall total was pricier than expected due to this and the price of parts but well worth it as my AC is functioning better than ever. Other than that great work!
