Save Money with Safe, Delicious, Drinking Water From Your Tap Say Goodbye To Expensive Bottled Water
Safe, drinkable tap water was once a given, but many people now doubt its safety and dislike its taste.
Many people have resorted to bottled water, which is expensive, inconvenient and environmentally unfriendly.
Now there’s a better solution.
You can once again have safe, delicious drinking water straight from the tap. Joseph Frederick & Sons’ water filtration team can test, diagnose, and treat your water so that you can be confident in its safety and happy with its quality.
Joseph Frederick & Sons can provide you with an inexpensive reverse-osmosis (RO) filter – or a whole-house system that will remove particles, cloudiness, rust, colors, and odors from your water. The RO filter mounts under your sink, or in the basement below your sink, providing you with unlimited fresh, purified water every day, without polluting the environment with plastic bottles.
Did you know:
• Drinking tap water costs about $0.23 per day for a family of four, compared to about $1.25 per day for bottled water.
• Bottled water produces up to 1.5 million tons of plastic waste per year.
• That plastic requires up to 47 million gallons of oil per year to produce.
• More than 80 percent of plastic bottles are simply thrown away, not recycled.

We look forward to serving you!
Joseph Frederick & Sons took the time to explain all my options to me. They provided me with a full detailed written estimate, the best price, and the best options of all the companies I contacted. The installation team was professional, courteous, and punctual. When done, they walked me through the use of my new thermostat and made sure I was comfortable with the new system. I was most impressed by the care they took in cleaning up. I would recommend them to anyone looking to replace their heating system or looking for quality service.”

Our heater broke and Joseph Frederick & Sons came out and diagnosed the problem. They were prompt and good at educating me about my choices. It was too expensive to fix the old one and then it might just break down again. We double checked all of the info on the Internet and they were right. They installed our new heater and humidifier. We got a good deal and they do really high quality work. They left the basement around the heater cleaner than when they started.”
