Water Softeners in Newmarket: Hard Water, Fixed and Proven

Newmarket water is hard. You already know it from the shower glass and the kettle. We install Canadian-made softeners, built in Barrie, and show you the hardness before and after.

Your number is above. Tell us your household and bathrooms and we quote the softener. We read your hardness before and after install so you see the difference. Here is how we install softeners.

On a well or lake intake: test it first

On a private well at the edge of Newmarket? That is not town water, and nobody tests it but you. Start with in-depth well water testing.

Local Water, Newmarket

Newmarket's water is hard. Here is the number.

Newmarket gets Lake Ontario water, brought up through Toronto and Peel, blended with York Region groundwater wells. York Region explains the supply. The latest York figure for Newmarket is 141 mg/L, about 8.2 grains per gallon. That is hard. Not very hard, and we will not tell you otherwise. Hard is enough to scale a water heater, crust a showerhead and spot every glass in the dishwasher.

The groundwater part of the blend shows in the iron: 0.103 mg/L, higher than the lake-only systems. Sodium is 23.0 mg/L. Neither is a safety issue. The water is treated, monitored and meets Ontario's standards. Hardness is a scale problem, not a health problem.

Newmarket has two kinds of housing. Glenway, Stonehaven, Summerhill and Woodland Hill are newer, and there the job is simple: a softener for scale and carbon for chlorine. The historic core around Main Street South, Park Avenue and the older streets off Eagle and Srigley has homes from the late 1800s through the 1920s, many with galvanized supply and lead solder somewhere in the walls. That is a drinking water question, and we handle it separately.

Either way, the proof is the same. We read your hardness before install and again after, at the same tap. You see both numbers.

  • Canadian-made softeners sized for Newmarket's hard water
  • Hardness read before install and after, at the kitchen tap
  • Carbon filtration for chlorine taste and shower smell
  • Reverse osmosis for drinking water in the older core
  • Repair and reprogramming on existing softeners
  • Fixed written price before any work starts

Hardness, Newmarket

Water softeners for Newmarket

At 141 mg/L, about 8.2 grains per gallon, Newmarket water leaves white crust on shower glass, scales kettles and shortens the life of water heaters. Tankless heaters in the newer subdivisions scale fastest. A water softener is the fix, sized from that number and your household, with a bypass to the outside taps so the garden gets untreated water.

We see plenty of softeners in Newmarket that were never programmed for the water. If yours is not keeping up, a reprogram or repair is often all it needs, and we will tell you so before we sell you anything new. For a new install, the baseline reading sets the program and the after reading proves it.

Filtration, Newmarket

Chlorine and rust

Newmarket water is chlorinated, and the taste at the kitchen tap and the smell in the shower are the next complaint after hardness. A carbon stage on the main line deals with it at every tap and sits beside the softener on one bypass. For a plain-language rundown of the rest, see what is actually in York Region tap water.

In the century homes around Main Street South, galvanized supply sheds rust that clogs aerators and stains sinks. A sediment stage catches it, though we will tell you when the lasting fix is replacing the pipe, which is a job for a plumber, not us.

Drinking Water, Newmarket

Reverse osmosis and lead in older homes

Homes built before the late 1980s can have lead solder, and the oldest may still have lead service lines. A lab lead test from the kitchen tap settles the question. Where lead shows up, reverse osmosis at the kitchen tap removes it, along with the sodium a softener adds.

Households asking about PFAS and pharmaceuticals get the same answer: test, then RO with the right media, then retest.

  • Lab lead testing for pre-1990 homes
  • Under-sink RO feeding the tap and fridge
  • Before and after testing to prove the result
How a softener install works in Newmarket

Before and after. That is the proof.

We do not ask you to take our word for it. Before we connect anything, we read the hardness at your tap. That is your baseline. We install, program the softener from that number, and read the same tap again. You see both readings. The after number tells you it works. It tells us it is set up right.

Common Questions

Hard water and softener questions in Newmarket

Is the water in Newmarket hard? +
Yes. York Region reports Newmarket at 141 mg/L, about 8.2 grains per gallon (2026 Q2 average). That is in Health Canada's hard band of 121 to 180 mg/L. Hard, not very hard.
Do I need a water test before you quote? +
No. The number is published. Your household and bathrooms are enough for a fixed written price. We read your hardness at install, before and after, so you see what changed.
Should I test for lead in an older Newmarket home? +
If the house was built before about 1990, yes. Lead solder was common until then, and the oldest homes near Main Street South may have lead service lines. A lab test from the kitchen tap is definitive.
Will a whole house filter remove the chlorine taste? +
A carbon filter where the water enters the house removes chlorine taste and smell at every tap. It does not soften water, so if scale is the problem you need a softener as well.
My softener is not keeping up. Do I need a new one? +
Often not. Many Newmarket softeners were never programmed for the water. A reprogram or repair may be all it needs.
How far are you from Newmarket? +
We are based in Keswick, straight up Woodbine Avenue.
