When it comes to choosing a supplier for your modified container project, price is often the first thing people compare. And that’s completely understandable — you want value for your investment.
But relying on price alone can end up costing you far more in the long run.
At Conteneurs Experts, we’ve seen too many clients come to us after a bad experience with a lower-priced supplier — one that didn’t deliver what was promised.
In this article, we’ll walk you through the 6 most common — and costly — mistakes to avoid when selecting your container supplier.
With the rising popularity of container transformations, the market has attracted less-than-reliable players — and even outright scammers.
Common mistake: sending a deposit to a company with no physical address, no real team, and no traceable history.
👉 What it can cost you:
Lost deposit
No legal recourse
Delays — or worse, a cancelled project
What to do:
Check reviews, verify the business registry, ask for past project references, and never send money without proof the company is real and established.
A quote with no plans, no specs, and no documentation? That’s a major red flag.
Common mistake: thinking a generic quote like “20’ office – $18,000” is enough to move forward.
👉 What it can cost you:
A finished product that doesn’t meet your expectations
Surprise add-ons later in the process
A unit that doesn’t serve its intended purpose
What to do:
At Conteneurs Experts, we provide detailed technical plans for every project, and nothing moves forward until the client approves them. Expect the same level of clarity from any professional supplier.
Two quotes might both say “modular office” — but one includes insulation, electricity, and interior finishing… while the other is just a basic container.
Common mistake: assuming offers are comparable based on surface-level descriptions.
👉 What it can cost you:
Paying extra for essentials after the fact
Blowing your budget
Ending up with an incomplete or unusable product
What to do:
Compare line by line. Beware of vague or overly simplified quotes.
A poorly modified container can pose serious risks, whether electrical, structural, or thermal — especially if it’s for commercial or public use.
Common mistake: thinking the cheapest option will “do the job.”
👉 What it can cost you:
Insurance refusals
Failure to meet local regulations
Safety issues
Expensive modifications to bring it up to code
What to do:
Ask who performs specialised work like electrical, plumbing, or HVAC. At Conteneurs Experts, we only use licensed professionals — because shortcuts in safety aren’t worth the risk.
A supplier offering to build your container in 2 weeks while others quote 6? That might sound great… but it’s often too good to be true.
Common mistake: assuming faster is better.
👉 What it can cost you:
Poor workmanship
Cheap materials
Technical or aesthetic issues
What to do:
A quality project takes time. Ask for a realistic timeline — and understand what’s actually happening during that time.
Once the container is delivered, what happens if you need help? A good supplier doesn’t disappear once the invoice is paid.
Common mistake: choosing the lowest bidder without thinking about what happens after delivery.
👉 What it can cost you:
No support if issues arise
Unplanned repair costs
Wasted time and added stress
What to do:
Ask about warranties, follow-up support, and how the company handles post-delivery service.
Choosing a container supplier based on price alone is often a false economy.
A modified container is a serious project — one that involves technical complexity, long-term durability, and often business-critical use. The right partner helps you avoid headaches, hidden costs, and disappointing results.
At Conteneurs Experts, we don’t claim to be the cheapest.
But we do commit to delivering a space that’s well built, well thought-out, and truly fit for purpose — with no surprises.
