Top 5 Mistakes Southampton Residents Make When Renting a Dumpster

If you’re a Southampton homeowner tackling a major cleanout, home renovation, or even just clearing out your garage, renting a dumpster can make the whole process faster and a lot less stressful. 

But before you dive into your project, let me give you a little insider advice.

Our Long Island dumpster rental company has delivered to homes and businesses for five decades — including plenty right here in Southampton. And believe me, we’ve seen it all: the perfectly planned cleanouts and the ones that went a little sideways.

So today, we want to walk you through the top five mistakes we see folks make when renting a dumpster in Southampton—and more importantly, how to avoid them.

1. Renting the Wrong Size Dumpster

This is by far the most common issue we run into. We get it—dumpsters aren’t exactly something you deal with every day. But choosing the wrong size can cost you, either in overage fees or wasted space.

Go too small, and you’ll fill it up halfway through the job and need a second dumpster. Go too big, and you’re paying for space you don’t need.

Here’s a quick breakdown to help you ballpark your needs:

• 10-yard dumpster – Great for attic or garage cleanouts, or small remodeling jobs like a half-bath.
• 15-yard dumpster – Perfect for decluttering before a move or light construction work.
• 20-yard dumpster – Ideal for full home cleanouts or medium-sized renovations.
• 30-yard dumpster – Best for major remodels, roof replacements, or large-scale debris.

Still unsure? Give us a call—we’ll help you pick the right size based on your project.

2. Skipping Permit Research

This one trips up a lot of Southampton homeowners. The town has pretty clear rules about where dumpsters can be placed. If you’re keeping it on private property like your driveway, you’re usually fine. But if the dumpster’s going on the street—or even partially blocking a sidewalk—you may need a permit.

The last thing you want is to get hit with a fine or have your project delayed. Always check with the Town of Southampton Building Department before delivery day, especially if street placement is your only option.

And don’t worry—if you’re not sure where to start, we’re happy to point you in the right direction.

3. Tossing Items You Shouldn’t

It might seem like anything and everything can go into a dumpster, but there are some important restrictions—especially here on Long Island, where waste disposal is carefully regulated.

Things you can’t toss in our dumpsters include:

• Paints, solvents, and other hazardous liquids
• Electronics like TVs or computers
• Tires and car batteries
• Propane tanks
• Refrigerators or AC units with Freon

If you’re unsure about an item, just ask us. We’d rather give you a straight answer than have you face a fine or waste time unloading prohibited materials.

For items like electronics, the Southampton Transfer Station usually accepts e-waste during designated drop-off days—definitely worth checking out.

4. Overloading or Improperly Loading the Dumpster

We see this one a lot, especially during construction or large cleanouts. When you’re in the zone, it’s easy to just start tossing stuff in. But there’s actually a right way (and a wrong way) to load a dumpster.

Here’s how to do it right:

• Break down furniture and large items whenever possible.
• Load heavier items at the bottom to keep things balanced.
• Keep everything below the top edge—nothing should stick out.
• Avoid tossing in dense materials like concrete or dirt unless your rental is rated for it.

Why does it matter? Well, overloaded or unbalanced dumpsters can’t be safely hauled away—and that can lead to delays and extra fees. Plus, if you’re tossing in heavier materials, you might exceed the weight limit. That’s why we always recommend estimating weight along with volume when you book.

5. Waiting Too Long to Schedule Your Rental

Southampton’s a busy place—especially during the spring and summer when everyone’s doing renovations, moving, or prepping their summer homes. If you wait until the last minute to book your dumpster, you might be out of luck—or end up paying a premium for rushed delivery.

We recommend calling at least a few days in advance. But honestly, the earlier the better—especially if you need a specific size or delivery window. We offer same- or next-day service when we can, but during peak season, things fill up fast.

So whether you’re planning a big backyard makeover or just cleaning out your basement, don’t wait until Friday afternoon to call us for a Monday project.

Bonus Tip: Work With a Local Dumpster Company

There are a lot of national brokers out there who’ll rent you a dumpster—but they don’t know Southampton the way we do.

When you rent from S&A Container Service, you’re working with a Long Island-based company that understands the local rules, neighborhoods, and pickup logistics. We’ve worked with homeowners in Sag Harbor, contractors in the North Sea, and businesses all across the South Fork.

That means faster response times, friendlier service, and fewer headaches for you.

Plan Ahead, Be Prepared

Renting a dumpster in Southampton doesn’t have to be a hassle—as long as you plan ahead and know what to watch out for. To recap, avoid these five common mistakes:

1. Don’t underestimate your dumpster size.
2. Double-check if you need a permit.
3. Know what’s allowed (and not allowed) in the dumpster.
4. Load smart—stay under the fill line and weight limits.

Book early, especially during peak season.
