Thank you so much for review!!! -Patrick Raimondo, CWS
Very happy with Certified Water Services and highly recommend. They were super knowledgable and affordable. Our water is better than ever!
Had a really good experience with Certified Water Services. They showed up on time, knew exactly what they were doing, and got everything taken care of without any hassle. Everyone I dealt with was professional and easy to work with. They also took the time to make sure I was happy with everything before they left, which I appreciated. Definitely a company I’d use again and recommend to others.
Thank you so much for the awesome review!!! Patrick Raimondo, CWS
Scoping of water treatment installation was based on needs analysis of treated water requirement and public water analysis for a single family home in NJ. Installation was flawless, knowledgeable and friendly staff. Lead time of equipment was short and delivery timeline was honored. Equipment operates very well so far.

From start to finish, Certified Water Services delivered. Victor gave me a refreshingly honest consultation — no pressure, no upselling, just straight talk about what I needed. Sean and Brendan handled the installation professionally and took the time to answer all my questions. They installed a whole-house carbon filtration system, water softener, and reverse osmosis drinking water system — all quality equipment, done right. The results speak for themselves. My skin feels better, the water spots, buildup, and discoloration are gone, and the drinking water is clean and fresh with zero chlorine smell. I noticed the difference sooner and more significantly than I ever anticipated. If you're considering a water treatment system, look no further. Highly recommend Certified Water Services and their team.
Thank you so much for leaving the review and the kind words!!! Patrick Raimondo, CWS
Great service and very professional. Have been clients for over 16 years.
Thank you so much for the review!!! Patrick Raimondo, CWS
Fantastic team to work with - very professional and transparent. After working with CWS it was immediately clear how unprofessional and unqualified certain other water companies are in the Bucks County area.
Thank you so much for the kind words!!! Patrick Raimondo, CWS
This Company is everything they said they would be. Prompt and professional installers at a fair price. No reason to go anywhere else for a water filtration system.
