Top 5 Mistakes Builders Make When Ordering Building Materials

Ordering building materials might sound straightforward, but small mistakes can lead to big cost overruns and project delays. Contractors in Ontario often face issues that could easily be avoided with better planning and supplier relationships. Here are the top five mistakes builders make when ordering materials — and how to avoid them.

1. Ordering the Wrong Quantity

• Under-ordering leads to delays waiting for more stock.

• Over-ordering ties up cash flow and storage space.

• Fix: Use accurate takeoffs and confirm measurements before ordering.

2. Choosing Price Over Quality

• Cheap materials often mean higher waste, faster wear, or non-compliance with building codes.

• Fix: Balance cost with quality by working with reliable suppliers.

3. Ignoring Lead Times

• Some materials (like engineered lumber or specialty siding) require weeks to arrive.

• Fix: Ask your supplier about stock availability and plan for delivery windows.

4. Mixing Suppliers for the Same Project

• Creates inconsistencies in material quality and finish.

• Fix: Stick with one supplier who can handle the full order.

5. Not Leveraging Contractor Pricing

• Builders lose margins by paying retail prices at big box stores.

• Fix: Work with a supplier like Confirmed Construction Materials that offers bulk discounts and contractor accounts.
