Windsor is a river town first. The Connecticut River runs the length of its eastern edge, and the Farmington River crosses the town from west to east before joining it. Water is part of daily life here, which is why basement seepage, slow drains and hidden leaks are worth watching for.
We take sewer line cleaning and leak detection calls in Windsor, along with burst pipes and sewage backups at any hour. Our base is in Simsbury, and Windsor does not border Simsbury. The trip is about 11.9 miles and about 24 minutes, an estimate without traffic, so we plan for the distance and say so up front.
Two rivers, one flood history
The National Weather Service tracks the Connecticut River at Hartford, downstream of Windsor. It is a Hartford gauge, not a Windsor one, but the NWS impact notes name Windsor directly. At 18 to 19 feet, flooding reaches low-lying land upstream of Hartford, including the part of Windsor where the Farmington empties into the Connecticut. Minor flood stage there is 16 feet.
The gauge shows the Tropical Storm Irene crest at 24.78 feet on August 31, 2011, and a provisional crest of 25.96 feet on December 14, 2023. The 1936 record is 37.6 feet. If you live near either river, those numbers explain why a wet spring can leave a basement damp for weeks. Check any floor drain and sump pit before the river rises, not after.
Meadow Brook and the low streets
In the southern end of town, the town's hazard records list two repetitive-loss flood properties next to Meadow Brook, with four insurance claims between them. The brook's culvert was replaced in 2007. The 2024 hazard plan also names Batchelder Road, Pleasant Street and River Street as roads that can become isolated in a flood.
For a homeowner on or near those streets, the plumbing lesson is practical. Keep the sump pump tested, and know where your sewer cleanout is. Windsor's weather page tells residents to call a local plumber to pump out a flooded basement, and our emergency line handles those calls.
Poquonock, Wilson, Rainbow and Hayden Station
The town's own history pages treat these as distinct villages. Emergency dispatch is available around the clock for all of them.
Poquonock
River Street runs near the Farmington River and is one of the roads the hazard plan flags for flood isolation. Street delivery here is 06095, while 06064 is reported as a PO Box ZIP. Check the sump pit before spring.
Wilson
Around Wilson Avenue, Pine Lane and Becker Circle, the L.P. Wilson Community Center is the town's designated emergency shelter. Know your shutoff before a storm sends you there.
Rainbow
Rainbow Road has a fire substation, and Rainbow Brook is one of the town's named streams. If your yard stays soggy after rain, ask us whether the water is coming from the ground or from a pipe.
Hayden Station and Windsor Center
Windsor Center sits around Broad Street and Palisado Avenue, near Town Hall. Across town, 2,078 homes date from 1939 or earlier, so ask for a camera look at older cast iron or clay drains.
MDC water, and the sewer plant in Poquonock
Windsor is one of eight Metropolitan District (MDC) member towns. Its water comes from the Barkhamsted and Nepaug reservoirs. The 2025 MDC report lists an average pH of 7.41 and calcium averaging 3.09 ppm, and says corrosion control keeps pH above neutral. It prints no hardness figure, so test your tap before buying a softener.
The MDC runs the Poquonock water pollution control facility on Poquonock Avenue, though which streets drain there is not confirmed. The MDC says the lateral, the pipe from your house to the main sewer, belongs to you, and it asks you to call its Command Center first when a backup hits.
If sewage is coming up in your basement, stop running water and call us and the MDC. A sewer line cleaning visit often shows quickly whether the clog is in your lateral or the street main.
Wells and septic inside an MDC town
Windsor's Health Department says many residents are still served by drilled, driven or dug wells, and many homes use septic systems. Its septic page links to the MDC pump-out reimbursement form. That reimbursement is up to $275 every three years for owners who cannot connect to the MDC sewer.
A septic home with a garbage disposal may need pumping sooner, because food waste builds up as scum and sludge. Connecticut's public health code also requires a code-compliant septic area to stay available on the lot, so check with the Health Department before adding a pool or shed. East Granby, which touches Windsor, is not an MDC member, so we never assume the same pipes from town to town.
Backup or leak in Windsor?
The 24/7 line is open all night, and same-day appointments are available when schedules allow.
How old Windsor houses are
What older Windsor homes mean for leaks
The Census figures are from the 2020 to 2024 American Community Survey. Of the 12,071 units, 2,078 date from 1939 or earlier, and 2,149 were built in the 1970s, the two largest groups. That mix means you will find everything from original cast iron drains to 1970s copper with aging solder in one town.
Hidden leaks in these homes often start small. A water bill that jumps with nobody home is the clearest sign, and a meter that still moves with every fixture off is stronger evidence. We use acoustic listening gear and thermal imaging for leak detection, then open the smallest hole that reaches the pipe. If the pipe itself is failing end to end, [[repiping]] may cost less than repeated repairs.
Sewer line cleaning versus a bigger repair
Which one you need depends on what the camera shows.
Cleaning the line
- Cable or hydro jetting clears roots, grease and scale
- Works when the pipe is still sound
- Roots can grow back, so cleaning may repeat
- Camera first shows whether the pipe is intact
Repairing the line
- Spot repair or replacement when a section has collapsed or sagged
- Needed when cleaning keeps failing within months
- Ask the Building Department whether your job needs a permit
- Digging requires an 811 call at least two business days ahead
Before we arrive in Windsor
Whether it is a burst pipe or a sewage backup, these steps protect your home while we travel to you. Keep the 24/7 line free.
Stop the water
Shut the main valve at the meter or where the line enters the house. On a well, switch off the pump breaker as well, so the tank stops feeding the leak.
Stop using drains
For a backup, do not flush or run sinks, showers or the washer. Every gallon you add goes to the lowest drain in the basement.
Stay out of standing water
If water covers outlets, the panel or a furnace, do not wade in. The MDC advises against touching electrical appliances or the fuse box while standing in water.
Photograph and note
Record where water first appeared, the time, and which fixtures acted up. If a flood is river-related, tell us before we come, as roads like River Street can close.
Nearby towns we also serve
Windsor touches Bloomfield, a mid-century MDC town with a different housing story, covered on our Bloomfield page. If you are comparing, Granby is a small town where most homes rely on private wells, with some public water districts with almost nothing in common with Windsor.
Frequently Asked Questions
Yes. ZIP listings show 06095 as Windsor's street delivery ZIP, covering Windsor Center, Wilson and most of the town. It also reports 06064 as a PO Box ZIP for the village of Poquonock, inside the 06095 area. Windsor Locks is a different town with its own ZIP.
Yes. The 24/7 emergency line takes Windsor calls overnight and on weekends for sewage backups, burst pipes and basement flooding. Because we travel from Simsbury, tell us on the call if roads near the river are closed.
About 11.9 miles and about 24 minutes by road without traffic, east-southeast of Simsbury. That is an estimate, and a bad commute or road closure changes it. Windsor does not share a border with Simsbury.
The MDC says the lateral from your house to its main belongs to the homeowner. Call the MDC Command Center first for a backup, then call us. Doing work before calling the MDC can affect whether it takes responsibility for the main.
Often it is groundwater, not a pipe leak. A sump pump with a working check valve helps, and a sewer backup is a separate issue. A homeowner policy usually excludes seepage and sewer backup unless you bought an endorsement, so ask your insurer.
Shut off every fixture and watch the water meter for two hours. If it moves at all, you probably have a leak. Then call us for leak detection to find where it is.
Windsor's permit pages never mention plumbing by name, so we cannot tell you a rule from them. The new home checklist does ask for plumbing details, sewer and water lateral locations, and septic or well information. Call the Building Department about your job before work starts.
