Garage Cleanout in New Hampshire: What It Costs and What You Can't Throw Away

What We Pulled Out of a Portsmouth Garage

The garage in the photos on this page sat in Portsmouth, and it looked like most of the garages we get called about. Cinder block walls, exposed joists with the insulation sagging out of them, and a floor you couldn't see.

A mattress and box spring leaning against the wall. An ironing board still standing up in the middle of the floor like somebody meant to come back to it. A folding chair, old yard tools, chairs, power tools, paint cans, lumberscrap, lumber stacked against the block, cardboard that had gone soft from years of damp, a blue tarp, trash barrels, and a workbench buried under whatever got set down on it last. Underneath all of it, a layer of dirt, sawdust and broken-down cardboard that had been building for years.

By the time we left, the homeowner could see the floor and walk from the door to the back wall without turning sideways. That's the whole job, and it's the one most people put off for another year because they don't know where to start or what they're allowed to throw away.

Here's how to do it, and what New Hampshire law actually says about the pile.

Why New Hampshire Garages Fill Up Faster Than People Expect

Almost nobody sets out to fill a garage. It happens one reasonable decision at a time. The snowblower comes in for the season and the mower goes to the back. A nor'easter knocks the power out and the generator, the gas cans and the tarps all find a corner. A bathroom gets redone and the leftover tile, half a bucket of thinset and four cans of paint go on a shelf because you might need them.

Then there's the part specific to living here. A lot of the housing stock across Rockingham and Strafford counties is old, and old houses up here have small basements, wet basements, or fieldstone basements you would not store anything valuable in. The garage ends up being the only dry storage on the property. Add the freeze-thaw cycle and the humidity coming off the water and half of what's out there quietly destroys itself. Cardboard goes soft, particleboard swells, paint freezes and separates, and anything with a bearing in it seizes up.

Which is why September through November is our busiest garage stretch. People want the car inside before the first real storm, and they finally admit the pile isn't going anywhere on its own. We've written before about a garage cleanout in Dover that started exactly this way.

Start With Four Piles, Not With Organizing

The most common mistake is trying to organize a garage that's still full. People buy shelving and bins first, spend a Saturday rearranging, and end up with the same volume of stuff in tidier containers. Nothing leaves. Six months later it looks the same.

Empty first, decide second. Pick a dry day, pull everything you can move out onto the driveway, and sort it into four piles: keep, sell or donate, special handling, and trash. Keep means it has a job in the next twelve months. Special handling is the pile this article exists for, and it's bigger in New Hampshire than most people expect.

Work in zones instead of attacking the whole garage at once. One wall, one bay, one shelving unit. Set a rule before you start so you're not relitigating every object: if it hasn't been touched in two winters and it isn't seasonal, it goes. Leave the sentimental boxes for last, because starting with a bin of photographs is how a cleanout turns into four hours on a folding chair and a driveway that's still full at dinner.

One caution from doing this for a living. Open the boxes rather than assuming. We always ask twice before anything leaves the property, because people stash cash, jewelry, deeds and titles in the garage far more often than you'd think.

What You Legally Cannot Throw Away in New Hampshire

This is where most garage cleanouts stall out, and New Hampshire works differently from Massachusetts in a way that catches people.

Massachusetts runs a long statewide ban list under MassDEP, which we cover in detail in our guide to items you can't throw away in Massachusetts. New Hampshire's statewide list is shorter, but the two things it covers are exactly what garages are full of.

Under RSA 149-M:27, you cannot dispose of electronics in the trash. That covers computers, laptops, monitors, tablets, printers, copiers, televisions and other video display devices, DVD players and VCRs, cordless and cell phones, and anything containing a lithium-ion battery that can't easily be removed. The tube TV on the top shelf and the dead printer in the corner both fall under it.

On top of that, as of July 1, 2025, rechargeable lithium-ion batteries are banned from New Hampshire landfills and incinerators outright. That covers every cordless tool battery, e-bike pack and power station sitting on a garage shelf. These are also a genuine fire hazard in a truck or a transfer station when they're damaged or swollen, which is a large part of why the ban exists.

Here's the part that trips people up most. Beyond those statewide rules, New Hampshire leaves a lot to the towns. Your transfer station sets its own accepted-items list, its own per-item fees, and its own rules on things like mattresses and box springs, which Massachusetts banned outright in 2022 but New Hampshire handles locally. What your buddy two towns over can drop off, you may not be able to. Call ahead before you load the truck, or you'll lose a Saturday finding out at the gate.

Separate from all of that is household hazardous waste, which can't go in the trash, can't go in a dumpster, and can't go in our truck either. In a garage that means oil-based paint and stain, thinner and solvents, motor oil, antifreeze, gasoline and old gas cans, pesticides and weed killer, pool chemicals and driveway sealer. Most New Hampshire towns run a household hazardous waste day once or twice a year, often as a regional collection shared with neighboring towns, and post the date on the town website. Propane tanks are their own problem and are easiest handed back through a cylinder exchange at a hardware store or gas station.

We can take some of this with the right handling and a small per-item fee, including paint cans, propane tanks, car tires, fluorescent bulbs, monitors and heavy-duty batteries, because they cost us more to dispose of properly. What we cannot take at all is loose oil and oil products, adhesives, asbestos, asphalt, and dirt, soil or gravel. We'd rather tell you that on the phone than in your driveway.

What a Garage Cleanout Costs in New Hampshire, and When a Dumpster Beats Junk Removal

There are two ways to empty a garage, and the right one depends on how you want to spend your weekend.

A dumpster in your driveway makes sense when the project is spread over a few weekends, you have help, and you'd rather do the lifting yourself to save money. A 20-yard is the size most garage jobs land in, it runs a flat rate on typical household material, and it sits there while you fill it on your own schedule.

Junk removal makes sense when you want it gone in one day and you don't want to touch any of it. We price on volume, meaning how much room the load takes up in the truck, with a minimum charge on small jobs. A full 20-yard load of typical garage material generally stays under two tons. Half a garage costs about half of a full one. You get a real number on site before we start, or a solid estimate from photos if you send them ahead.

Where junk removal earns its money is the awkward part of the job: the freezer nobody has opened since 2019, the workbench that has to come apart to fit through the door, the tube TV on the top shelf, the treadmill that takes three people. It's also the answer if your driveway can't take a container, or you're on a street where a dumpster sitting out for a week starts a conversation. We laid out the whole comparison in a job we did in Raymond where the homeowner was sure she needed multiple dumpsters and actually didn't.

Whichever way you go, the number we quote is the number you pay. No heavy-item charges invented in the driveway, and anything still usable gets donated instead of thrown away.
