Everything a Seacoast cleaning visit handles
Each visit works through the pool in a set order so one job does not undo another. Your technician skims the surface, brushes the walls and steps, vacuums the floor, empties the skimmer and pump baskets and checks the filter. Testing and balancing the water comes last, so the readings reflect a clean pool rather than one full of debris. You do not need to be home for any of it. As long as the technician can reach the pool and the equipment the visit goes ahead while you are out, so arrange gate access in advance and mention pets or alarms along the route. When the work is done you receive an E-Report with the chemical readings plus before and after photos, which builds a running record of your pool over the season.
Durham tap water and the phosphate question
In Durham most public water comes from the UNH/Durham Water System, which the University of New Hampshire runs jointly with the Town's Public Works Water Division. Its 2025 Water Quality Report lists two surface sources, the Lamprey River and the Oyster River, treated at the UNH Water Treatment Plant along with the Spruce Hole Well and the Lee Well. Treatment includes an orthophosphate corrosion inhibitor. That protects household pipes, yet phosphate can also feed algae once the same water sits in a warm and sunny pool. Dover adds zinc orthophosphate to its supply for the same reason and Portsmouth water carries poly and ortho phosphate. Clear fill water can still be feeding the next bloom, so a steady sanitizer level and regular brushing count for more here than the look of the water suggests.
Hardness changes from one town to the next
Your pool chemistry starts with whatever comes out of the hose. On the Seacoast that depends on the address. According to Portsmouth's 2025 Consumer Confidence Report, customers in Madbury, Durham and part of Newington along the Portsmouth transmission main receive Portsmouth water. That report gives an average hardness of 44 mg/L as calcium carbonate with a range of 13 to 204 mg/L. It explains the spread as the difference between reservoir water and groundwater, so the wells serving Greenland and south Portsmouth run harder. Dover's 2026 report describes most of its treated water as moderately hard, with samples of 22.0 mg/L at the Hughes Well and 78.24 mg/L at the Calderwood Chemical Building. With numbers moving that much within a short drive, your technician tests the water at your pool on every visit instead of assuming a town average.
Private wells bring their own chemistry
Properties outside the public systems rely on private wells. The New Hampshire Department of Environmental Services says nearly half of the state's residents get their water from a private well. NHDES also notes that arsenic and radon occur naturally in New Hampshire rock and soil, as do manganese and coliform bacteria. The agency recommends that well owners test regularly. For a pool the most visible of these tends to be dissolved metal. Manganese and iron can stain pool surfaces if they are not managed, which is why a stain that appears after a top up deserves a closer look. If your pool is filled from a well, share your latest well test with your technician. It gives a far better starting point for balancing than a guess based on the water next door.
Summer heat and a weekly rhythm
NOAA's 1991 to 2020 normals for the Durham station in the UNH area put the July average high at 82.5 F, with about 15.1 days a year at or above 90 F. Warm water uses up sanitizer faster. A hot weekend with a full pool can shift the chemistry well before the next visit is due. That is why most pools in regular use are serviced weekly through the season while pools used lightly or kept covered often do well every other week. Your technician will suggest a schedule based on how the pool is used and the tree cover above it. Between visits empty the skimmer basket if it fills and run the pump long enough to turn the water over each day. If the water turns cloudy or smells strongly of chlorine, tell your technician rather than waiting.
Durham NH Pool Cleaning: Frequently Asked Questions
Where does Durham's public water come from and does it affect my pool?
The UNH/Durham Water System, run jointly by the University of New Hampshire and the Town's Public Works Water Division, draws on the Lamprey River and the Oyster River plus the Spruce Hole Well and the Lee Well, according to its 2025 Water Quality Report. Treatment includes an orthophosphate corrosion inhibitor. Phosphate protects household pipes but can feed algae once that water is in a warm pool, fountain or hot tub, so a steady sanitizer level matters.
Some Durham homes get Portsmouth water. How hard is it?
Portsmouth's 2025 Consumer Confidence Report says customers in Madbury, Durham and part of Newington along the Portsmouth transmission main receive Portsmouth water. The same report gives an average hardness of 44 mg/L as calcium carbonate with a range of 13 to 204 mg/L. That spread is wide enough that your own water should be tested rather than assumed, especially in a small hot tub where minerals concentrate.
When should I open my pool in Durham, New Hampshire?
NOAA's 1991 to 2020 normals for the Durham station put the median last spring freeze on May 8, with the May average high reaching 68.4 F. That is about a week later than the coastal Greenland station near Portsmouth. Opening after the last hard freeze protects the restarted equipment, while opening before algae takes hold under the cover makes the water easier to clear.
Will I know what was done at each cleaning?
Yes. Every visit ends with a real time E-Report showing what was done, the chemical readings and before and after photos, so you can see the result without being there.
Why is my pool still cloudy right after a cleaning?
Cleaning removes debris and corrects the chemistry, but the filter still needs time to clear fine particles from the water. Slight cloudiness usually settles as the pump runs. If it does not clear, or it gets worse, let your technician know so the filter and chemistry can be checked.
