Container rental for building sites: 8 common mistakes to avoid

Renting a container for a worksite in Montreal seems like a formality… until the unpleasant surprises arrive: the wrong-sized container, rejected waste, missed pick-up deadlines. These unforeseen events can slow down work, increase costs, or simply complicate your logistics.

At SMAG Express, we know that a good job starts with efficient waste management. That’s why we’ve listed the 8 most common mistakes to avoid when renting a container.

1. Choosing a container that’s too small… or too big

One of the most common mistakes is to rely on “eyeball” estimation. The result: waste piles up beyond the edges, or the container arrives half-empty. In both cases, you lose time and money.

Case in point:

A customer in Villeray ordered a 10-cubic-yard container to empty a complete basement prior to renovation. After 2 days of work, the container overflowed. The result: an emergency call for a second container… and double the cost.

Our advice:

  • Make a list of what you’re going to throw away (materials, objects, debris).
  • Compare with our guide 👉 How to choose the right container size for your renovation work?
  • Contact us: our team knows the typical volumes for each type of project (roofing, kitchen, complete demolition…).

2. Failure to check site accessibility

Even the best plan can fall apart if the driver can’t get the container to where it’s supposed to be.

Case in point:

A contractor in Ahuntsic had planned to install a container in an alleyway… too narrow for the delivery truck. Result: rescheduling of the depot, loss of half a day’s work.

Our advice:

  • Check the width of the entrance (3 meters minimum recommended).
  • Identify obstacles: trees, cables, steep slopes, parked vehicles.
  • Send a photo of the entrance to SMAG Express: we always validate accessibility.

3. Throwing away prohibited materials

Montreal’s sorting centers impose strict rules. Certain types of waste must not be disposed of in standard containers, under penalty of additional charges, penalties or refusal of collection.

Items to avoid:

  • Paints, glues, solvents
  • Propane tanks, tires
  • Electronic devices, light bulbs
  • Toxic or contaminated materials

SMAG tip:

On delivery, we provide you with a clear list of accepted/rejected waste. In case of

4. Don’t plan your rental period properly

It’s tempting to take a container for just 1 or 2 days to save money… but delays are common. Bad weather, lack of manpower or unforeseen discoveries extend the actual duration of the project.

Example:

A customer in Laval had scheduled 2 days’ rental for the demolition of his garden shed. After a day of rain, the work took 4 days. The container was kept for another 3 days… with penalties.

Our advice:

  • Plan for a realistic duration, with 1 or 2 safety days.
  • At SMAG Express, you can easily extend your rental period on request.

5. Forget municipal permits

In many Montreal boroughs, placing a container on the sidewalk or street requires a permit. Otherwise, you risk a fine, or even the removal of the container by municipal services.

Real-life case :

A Plateau Mont-Royal customer was fined $250 for placing an unauthorized container on the street.

Our advice:

  • Check whether the container will be on private or public land.
  • If it’s public, apply to the city for a permit.
  • We can help you with the administrative formalities if required.

6. Incorrect positioning of container

An improperly placed container can cause access problems or damage your property (lawn, paving stones, etc.).

Risks :

  • Soil compaction
  • Blocking access to vehicles or tools
  • Difficulty filling it or having it removed

Our advice:

  • Place the container on a hard, flat surface.
  • Protect your site with boards or planks.
  • Place it close to the work area (ideally within 10 meters).

7. Do not read contract conditions

Many customers quickly sign without reading the conditions, which leads to misunderstandings about :

  • Time included in the rate
  • Surcharge or express pickup charges
  • Refused waste

At SMAG Express :

  • Everything is clear, transparent and there are no hidden costs.
  • Our contracts are simple and easy to read, and our team explains everything to you before you sign.

8. Don’t ask questions before booking

Booking a container with no questions asked may seem quick… but it often leads to the wrong size, the wrong location or unexpected costs.

Example:

A Rosemont customer ordered a 20-cubic-yard container when his job required just 8. The result: unnecessarily high costs.

Our advice:

  • Call us before you book: we’ll ask the right questions and recommend the best solution.
  • Online or by phone, our team will guide you free of charge.

Renting a container can greatly simplify a worksite, provided you avoid these common mistakes. The right choice, planning and communication can save you time and money.
