Renting a rolloff dumpster should make your project easier—not more stressful. But for many homeowners and contractors in Longmont, Colorado, the process can come with unexpected headaches if you don’t know what to watch out for.

At McCoy’s Junk Removal, we’ve delivered hundreds of dumpsters across Longmont, Firestone, Erie, and the surrounding area. Along the way, we’ve seen the same avoidable issues pop up again and again.

Here’s how to avoid the most common dumpster rental mistakes in Longmont, so you can save time, money, and hassle.


1. Renting the Wrong Size Dumpster

This is hands down the most frequent mistake. Too small, and you’ll end up needing a second dumpster. Too large, and you’ll overpay for space you don’t use.

McCoy’s offers three practical sizes:

  • 9-yard: Ideal for garage cleanouts or small DIY projects
  • ✅ 11-yard: Great for kitchen or bathroom remodels
  • ✅ 15-yard: Best for full-home cleanouts or landscaping overhauls

2. Ignoring Weight Limits

Every dumpster has a weight allowance—and going over it can mean surprise fees.

Things like:

  • Concrete chunks
  • Dirt and gravel
  • Shingles or roofing debris

…can quickly put you over the limit, especially with heavy construction material.

Tip: Ask about included tonnage before you book. At McCoy’s, we help you estimate weight so you don’t get hit with unexpected charges.


3. Placing the Dumpster in the Wrong Spot

Another common issue: choosing a drop-off spot that’s inaccessible or violates local codes.

In Longmont, dumpsters placed in the street may require a permit through the City of Longmont Public Works Department. But if you have a flat, clear driveway, that’s often the best choice.

Also: make sure the spot is:

  • ✅ Free of low-hanging branches or wires
  • ✅ Not blocking traffic or driveways
  • ✅ On level ground to prevent tipping

4. Throwing in Prohibited Items

A big one: dumping restricted items like paint, tires, batteries, or chemicals.

These can cause your load to be rejected or incur extra disposal fees due to hazardous material regulations in Boulder County.

Common prohibited items include:

  • Wet paint or solvents
  • Electronics with screens
  • Tires or vehicle batteries
  • Asbestos or industrial chemicals

5. Overfilling the Dumpster

It’s tempting to squeeze in just a little more—but overfilled dumpsters are unsafe to haul and could be rejected on pickup.

Best practices:

  • Don’t stack materials above the rim
  • Load heavier items on the bottom
  • Break down bulky furniture when possible

6. Not Booking Early Enough

Need a dumpster same-day or next-day? That’s not always possible—especially during peak seasons like spring and summer.

Avoid this mistake by booking 2–3 days in advance. McCoy’s offers flexible scheduling and prioritizes local deliveries across Longmont, Firestone, Berthoud, and surrounding areas.


7. Choosing the Wrong Company

Not all dumpster rental providers are created equal. Some companies charge hidden fees, don’t show up on time, or leave you hanging on pickup.

Here’s why homeowners and contractors trust McCoy’s:

  • ✅ Transparent, upfront pricing
  • ✅ Fast delivery and pickup
  • ✅ Friendly, local service
  • Rolloff dumpsters tailored to residential and light commercial use

Need something more than a dumpster? Our junk removal team can do the heavy lifting for you.
