The NEPA Winter Prep Checklist (the one we actually use)

If you've lived in Northeast Pennsylvania for more than one winter, you already know the drill: November shows up cold, December shows up colder, January punishes you for any procrastination, and February is the month your furnace dies at 2am and you find out which contractors actually answer the phone.

This is the checklist we run on every Pro-tier home before the first hard freeze. It's the one we actually use — not a generic "13 winter prep tips" SEO listicle written by someone in Florida. NEPA winters break houses differently than winters in Pittsburgh or Philadelphia, and the prep needs to match.

If you don't want to do any of this yourself, that's fine — our subscription plans cover all of it and you'll never have to think about it again. But if you want to handle it yourself, here's exactly what we'd tell you to do.

Why NEPA winters break things differently

Three things make Northeast Pennsylvania particularly hard on houses:

The freeze-thaw cycle. Pittsburgh stays cold once it freezes. The Lehigh Valley warms up between cold snaps. NEPA does both — Lackawanna County sees an average of 85 freeze-thaw cycles per winter, where the temperature crosses 32°F. Every cycle, water gets into a crack, freezes (expanding 9% in volume), then thaws and recedes — leaving a slightly bigger crack behind. Concrete, mortar, gutters, roofing — they all suffer.

Heavy wet snow followed by ice. Lake-effect snow off Lake Erie sometimes makes it across the state. Coastal storms riding up the Atlantic dump heavy wet snow and rain. The combination loads roofs and gutters with weight that flat midwestern snow doesn't.

Old housing stock. A lot of NEPA's homes were built between 1900 and 1960, with cellar walls of native stone or hand-poured concrete, balloon framing, and cast-iron drains. None of these were engineered for the winters we now have, especially the freeze-thaw frequency that's increased over the last 20 years.

The exterior checklist (do this first)

Always start outside. Once it's snowing or below freezing, half this list becomes either dangerous or impossible.

Walk the perimeter

Take 20 minutes and walk slowly around the entire house. You're looking for three things:

• Cracks in foundation walls. Especially horizontal cracks (vertical cracks are usually settling and less urgent). Anything wider than the edge of a quarter needs to be sealed before the freeze cycle widens it.
• Loose or damaged siding. Wind storms in November have a way of finding any panel that's already half-detached. Push on suspect panels — they should feel solid.
• Trees with dead branches over the house. Heavy wet snow brings these down. Anything bigger than your wrist that's hanging over the roof, garage, or power lines should come off before snow season.

Seal exterior penetrations

Every place a pipe, wire, or vent enters the exterior wall is a potential entry point for cold air, water, and mice. Use a quality exterior-grade sealant (we use OSI Quad Max — it stays flexible at low temperatures, unlike standard silicone). Pay particular attention to:

• Hose bib penetrations
• Dryer vents (and check the vent flap actually closes)
• Around HVAC line sets where they enter the house
• Cable, satellite, and electrical service entries

Caulk the windows

Specifically the exterior caulk where the window frame meets the siding or trim. This shrinks every summer and cracks every winter. If you can see daylight at any window edge from inside on a sunny day, that window is leaking heat all winter long.

Gutters and roof — the freeze-thaw battlefield

This is the single highest-leverage item on this whole list. Bad gutters cause 80% of the winter water-damage calls we get.

Clean them. Actually clean them.

Not "I had a kid scoop out leaves last weekend." We mean a thorough clean where every bit of organic matter is removed and the downspouts are flushed clean with water. Why this matters: leaves trap water, water freezes, ice expands, gutters separate from the fascia, water then runs behind the gutter and into the wall.

Check the downspout extensions

Every downspout should discharge water at least 4 feet from the foundation. If you have decorative splash blocks 6 inches from the wall, you're aiming a firehose at your basement every storm. Run a flexible extension that empties into the lawn, away from the house. In winter, this becomes critical — if the ground around the foundation freezes saturated, you'll get heave damage.

Look up

From the ground, with binoculars or a phone zoom, scan the roof for:

• Missing or curling shingles. Especially at the rake (the slope edge) and ridge.
• Damaged flashing. Where the roof meets a chimney, a wall, or a vent — these are leak points.
• Sagging in the gutter line. Indicates a structural problem with the fascia or the gutter brackets.

Ice dam prevention

If you've had ice dams before, you'll get them again unless you fix the underlying cause — which is almost always inadequate attic insulation or air sealing, not the gutters. We have a whole separate guide on ice dams because the problem is widely misunderstood. The short version: ice dams form when warm air from the house heats the underside of the roof, melting snow, which refreezes at the cold eaves. Fixing gutters does not fix this.

Water lines and outdoor spigots

Frozen pipes are the #1 reason for emergency calls between January and March. Every one we've ever responded to was preventable.

Disconnect every garden hose. Today.

Even if you have frost-free spigots, leave a hose connected and the spigot can't drain — the water sits inside the pipe, freezes, and splits the pipe behind the wall. You won't know until spring when you turn on the water and your basement floods.

Insulate any pipe in an unheated space

Garage, crawl space, attic, exterior wall — any pipe in these spaces gets a foam pipe sleeve. They cost about $3 per 6-foot length at any hardware store. A burst pipe costs $2,000-$15,000. Math is easy.

Find your main shutoff. Make sure it works.

If a pipe bursts at 2am, you have about 90 seconds before the water damage gets serious. If you don't know where your main shutoff is and can't operate it in the dark in a panic, you have a much bigger problem than a frozen pipe. Find it. Tag it. Make sure it actually closes (turn it off and on once — old gate valves seize).

Drain irrigation systems

If you have an in-ground sprinkler system, it needs to be blown out with compressed air before the first hard freeze. This is a one-time annual service that costs about $75-$120. Skip it and you're looking at $1,500+ in spring repairs.

Heating system — what to actually check

You don't need to be an HVAC tech to do basic heating prep. Skip the "have a professional inspect your furnace annually" advice you'll find on every other site (we'll get to that). Here's the stuff that actually matters month-to-month:

Replace the furnace filter

Every 3 months minimum during heating season. Sooner if you have pets or run the system hard. A clogged filter makes the system work harder, runs up your bill, and shortens equipment life. The 1-inch pleated filters are fine for most homes — you don't need the expensive HEPA filters unless someone in the house has serious allergies (those actually restrict airflow too much for many systems).

Test the system before you need it

The first time you turn the heat on in October, if there's a problem, you have a month to deal with it. The first time you turn it on in December, you're competing with everyone else who waited. Don't wait.

Check carbon monoxide detectors

You should have one on every floor and within 15 feet of every sleeping area. Test them. Replace batteries. If they're more than 7 years old, replace the unit entirely — the sensor degrades.

Look at the flue

If you have a gas furnace, water heater, or boiler, look at where the flue exits the house. The cap should be intact, no obvious damage, no blockage from a bird's nest. Carbon monoxide problems usually trace back to a blocked or damaged flue.

Yes, get the annual inspection

For furnaces, boilers, and especially heat pumps, an annual inspection by a qualified tech catches things you can't — heat exchanger cracks, refrigerant levels, ignition issues. It's worth the $150-$250. All our Essential-tier and above subscriptions include this as part of your monthly fee.

Interior prep most people skip

Reverse your ceiling fans

Ceiling fans should run clockwise (looking up at them) on low speed in winter. This pulls cold air up the center of the room, which forces the warm air at the ceiling down the walls and into the living space. Real impact: 4-6% reduction in heating costs in rooms with high ceilings. Free to do.

Check basement humidity

Winter basement humidity should be 30-50%. Above 50%, you risk mold growth on stored items and structural members. Below 30%, you're losing too much heat to evaporation. A $15 hygrometer from Amazon tells you exactly where you stand. Adjust with a dehumidifier (or in some old NEPA homes, just better basement ventilation).

Bleed the radiators (if you have hydronic heat)

Old hot-water heating systems collect air in the radiator at the highest points in the house. The radiator gets hot at the bottom, cool at the top. Use a radiator key, open the bleeder valve until water (not air) comes out, close it. Have a towel ready. Do this with the system running.

Test smoke alarms

You'll spend more time inside in winter, with the heat running, with candles lit, with a Christmas tree drying out. Statistically, December and January are the highest-risk months for house fires. Test the alarms now.

The emergency kit you'll wish you had

Power outages happen. NEPA-PRO responds to dozens during a typical winter — usually trees on lines after a wet snow. Have these things in one place where you can find them in the dark:

• Flashlights with fresh batteries. One per family member. Headlamps are better than hand-held — keeps your hands free.
• A battery-powered or hand-crank radio. Phones die fast in cold weather and cell towers go down too.
• Extra phone chargers — including a battery bank. Anker brand, 10,000+ mAh.
• Bottled water. 1 gallon per person per day, minimum 3 days. If you have a well, you have no water during a power outage.
• Non-perishable food. Three days worth. Don't forget a manual can opener.
• Warm blankets and sleeping bags. If the heat goes out, the family migrates to one room and bundles up.
• A standard non-electric corded phone. Plugs into your old phone jack. Works during a power outage if you still have copper landline service. If you've cut the cord (most people have), this isn't needed.
• Cash. Two hundred dollars in twenties. ATMs and card readers don't work without power.

If you have a generator

Run it for 15 minutes once a month, all year, with a load on it. Generators that sit unused develop fuel system problems and won't start when you actually need them. Use a stabilizer in the gas. Never, ever run a generator inside a garage or close to the house — carbon monoxide kills people every winter doing this.

If you have solar panels

NEPA solar systems are unusual because we get heavy snow. Most installations are designed with this in mind, but a few things are worth checking before winter:

• Don't try to sweep snow off panels. You'll scratch them. Modern panels shed snow on their own once any sun hits — usually within 24-48 hours. The lost production isn't worth a $4,000 panel replacement.
• Check inverter status via your monitoring app. If you see error codes, address them before winter — service calls become harder to schedule once snow shows up.
• Make sure the inverter cabinet is clear of snow. If it's wall-mounted, drift can pile up against the vents.
• Check for animal nesting. Squirrels and birds love the warm, dry space under the panels. They chew wires. Critter guards are cheap insurance ($300-500 installed).

When to hire it out

Some of this you can absolutely do yourself. Cleaning gutters, replacing filters, walking the perimeter — these are reasonable weekend projects.

Here's where we'd encourage you to call someone:

• Anything on the roof. The fall isn't worth the savings.
• Heating system inspection. Cracks in heat exchangers can kill people. Pay a pro to look once a year.
• Insulation upgrades. Best ROI on most NEPA homes is air sealing and attic insulation. Worth doing right.
• Generator installation. Plumbing in propane or natural gas is not a DIY job.
• Solar service. Don't get on a roof with electrical equipment unless you're trained and properly equipped.

Or just don't think about any of it

That's literally what our subscription plans are for. The NEPA-PRO Pro plan ($199/mo) includes a monthly visit, seasonal HVAC and gutter service, and a written annual property condition report. We do this checklist, plus the spring version, plus the summer version, plus the fall version, on autopilot. You get an itemized service log and a tech you actually know by name.

If you've made it this far down the page, you clearly take care of your house. We'd rather work with people like you than people who only call when something's already broken.
