Serving all of Maryland, Virginia, and Washington D.C. for superior Water Treatment and Well Pump Service
"The knowledge, expertise and service provided by David is second to none. National Water Service installed water softening, and reverse osmosis filtering system that has made an incredible difference in our home. We have no more residue build up in the bathrooms and kitchen on surfaces, and using filtered water has improved both the food and drinks we prepare but also makes our humidifiers and air filters far more clean and effective. I highly recommend National Water Service, especially for homes on well water."
"Exceptional customer service. My experience in the past with individuals who are providing a service, some tend to be pushy or obstructive but my technician did not have a dismissive attitude. Pat was patient, honest, and extremely informative. Deserving of praise. Thank you, sir.😊"
"David at National Water Service is the best in the business. He came over to test my water and spent so much time with me explaining "All Things Water". He went above and beyond as he always does. He is extremely responsive, professional and trustworthy. I highly recommend National Water Service!"
"Great service! Professional and knowledgeable technician. Easy to schedule and they send text or email with reminder and notification that they are on the way."
"Outstanding service, & professionalism. Highly recommend this company!"
"The pair of technicians who came out to our property to service an in-ground well-house braved rain, cold, and several scary-looking-but-non-threatening black snakes to put everything back ship-shape. Great Job!"
"Knowledgeable and patient technicians that explain the systems well. Prompt scheduling and excellent communication. I am always happy when entrusting our home with National Water."
"Excellent service as always."
"They are professional, on time and they get the job done in a reasonable time. National Water Services highly competent to handle any of your well water needs. I am beyond satisfied with the service that they have provided.."
The two-person crew came right on time and did a thorough job of examining the problem and explaining every step of the work they were doing. They were very friendly and helpful. The price was very fair.
The last service we had marks the 4th year we've had our system in place. Each year the service is done on time, hassle free, and with a technician highly knowledgeable about the system and local water supply. Not only is this water system highly efficient, but it's more affordable than other systems we've had. You can't go wrong with NWS!
The technician Paul was very friendly, educational, and answered all my questions. I felt he was trustworthy and honest. Our service appointment was good. I would recommend NWS.
[Service, Timeliness, Technician] no matter the reason for my call, there is always someone available to handle our needs. yearly maintenance is done on our water system by the same man who helped install it, Paul. i love dealing with him. he is efficient, knowledgeable and pleasant. the owner David has helped me at all hours of the day in any mini-crisis we have experienced and given us tons of information on how things work. i depend on him to educate me as well as advise. I am thrilled to recommend their services and have done so often.
From Matt at customer service to Josh our technician, everything was excellent and easy. Josh did a great job with the repair. I highly recommend this company.
National Water Service Corp. was fantastic to work with. They were informed, efficient, and polite, and they knew exactly what we needed for our particular situation. They had the equipment ordered and installed in a matter of days. David was a pleasure to work with and we will definitely use them again for future projects in our home!
