A Merrimack River town on Nashua's east bank

Hudson sits on the east bank of the Merrimack River in Hillsborough County, directly across the water from Nashua, with the Massachusetts line running along its southern edge toward Tyngsborough and Pelham. It is one of the larger towns in southern New Hampshire, and it grew from farmland into a busy suburb over the back half of the last century, which is why the housing here runs the full range - older village homes down near the river, block after block of postwar ranches, capes, and split-levels, and newer subdivisions spread across the higher ground toward Litchfield and Pelham. Benson Park, the old Benson's Wild Animal Farm, and the ponds and woods around Robinson Pond and the Musquash conservation land are reminders that this is still part rural town, part bedroom community. Keeping a home comfortable and dry here means working with the river, the granite underneath it, and a real New England winter, and it starts with the season this town is built around.

Southern New Hampshire winters put your heating on trial

Even down here in the Merrimack Valley, the heating season stretches from November into April, and a hard cold snap can drop overnight lows well below zero. That is when an aging or undersized furnace or boiler shows its age - not in mild weather, but on the single coldest night, when a no-heat call stops being an inconvenience and becomes a frozen-pipe emergency. We size heating to a real load calculation for the house instead of a rule of thumb, service furnaces and boilers before the cold arrives rather than during the first deep freeze, and when a system reaches the end of its life we replace it with equipment matched to what a Hudson January actually asks of it. Heat that holds through the coldest week is the entire reason you own the system.

Cold-climate heat pumps and a humid valley summer

Modern cold-climate heat pumps now hold their efficiency well below freezing, which makes them a genuine option even in a New Hampshire winter, and paired with backup heat for the hardest stretches they heat, cool, and dehumidify a home from one system. New Hampshire's utility rebate programs have made them more affordable to install than most homeowners expect. Summer in the valley is the other half of the job: July and August turn hot and sticky, and humidity is where air-conditioner sizing matters most. An oversized unit cools the air fast but shuts off before it pulls the moisture out, leaving the house cool and clammy and the basement musty. We size to the actual load, set the dehumidification up properly, and for older Hudson homes that were built without ductwork we add ductless mini-splits that deliver comfort in both seasons without tearing plaster apart.

Private wells and New Hampshire granite

The developed western and central parts of Hudson are largely on Pennichuck municipal water, but plenty of outlying homes toward Pelham and Litchfield still draw from private bedrock wells, and that water comes straight out of New Hampshire granite. That bedrock is the reason this state has some of the highest levels of naturally occurring arsenic in the country, and the same rock releases radon and uranium into well water and leaves it hard and heavy with iron and manganese. Arsenic and radon are the dangerous ones precisely because you cannot see, taste, or smell them, and the only way to know what is in a well is to test it. We test for what is actually present rather than guessing, then build the treatment the results call for - arsenic removal, a radon system, a softener for the hardness, filtration for iron and manganese - so the water is safe to drink and your plumbing and appliances last the years they should.

The Merrimack, the brooks, and a wet basement

The river that defines the town also floods it. The Merrimack has topped its banks in the big spring events - the Mother's Day flood of May 2006 put water through the low-lying stretches of the valley on both sides - and Hudson's smaller brooks and its high water table keep basements damp even short of a true flood. Homes on low ground fight groundwater pressing against the slab every wet spring. A sump pump is the front line there, and a sump with no backup fails on its one big test, because the water peaks during the same storm that knocks the power out. We install sump systems sized for real storm volume, add battery or generator backup so they keep running when the grid does not, and fix the grading and drainage that let water reach the foundation in the first place.

Postwar homes, older panels, and modern loads

A huge share of Hudson's housing went up in the building boom that turned the town into a Nashua suburb, and those 1950s-through-1970s ranches, capes, and splits were wired for a very different house than the one you live in now. Many still run on undersized panels, old fuse boxes, or the aluminum branch wiring of that era, none of which was meant to carry today's central air, electric ranges, heat pumps, and car chargers. That is both a safety issue and a hard ceiling on what you can add. We upgrade services to a safe 200-amp panel, replace outdated and aluminum wiring with proper routing, and add the circuits a modern home needs - including a correctly installed EV charger - all done to code and inspected.

Power that stays on through an ice storm

Southern New Hampshire's worst outages come from ice, not snow. The December 2008 ice storm coated the region and left parts of the state without power for days, and every hard nor'easter and ice event since has taken lines down across Hudson and its neighbors. A whole-home standby generator keeps the heat, the water, and - on a low valley lot - the sump pump running through a multi-day outage, starting on its own when the utility drops and shutting down when it returns. That is not a luxury here; it is the difference between a warm, dry house and frozen pipes over a flooded basement during the exact storm that cut your power.

Our own research, sourced and dated, on the problems that come up around here.

• Microplastics: What We Know and What We Do NotMicroplastics are in tap water, bottled water, food, air, and human blood and placental tissue. The WHO says current levels do not appear to pose a health risk. Both of those statements are true. Here is how to hold them at the same time.
• Pesticides in Your Drinking Water: The Atrazine ProblemAtrazine has been banned in the European Union since 2004. It is still one of the most heavily used herbicides in America and one of the most frequently detected pesticides in drinking water. The federal limit was set decades ago.
• Hormones and Pharmaceuticals In Your Drinking WaterEvery prescription filled in your town eventually reaches the watershed. The concentrations are tiny, nobody is required to test for them, and the fish downstream are telling us something. Here is what the evidence supports and what it does not.
• BPA, Phthalates and Endocrine DisruptorsBPA shows up in over 90% of Americans tested. The BPA-free replacements look like they behave the same way. These compounds are not on any drinking water report, and conventional treatment does not remove them.
