Step 2. Precision measurement

To make that possible, our sales representatives are specially trained to take precise, detailed measurements during your consultation. This step ensures your new products will fit perfectly, perform as promised, and look seamless in your home.
Unlike companies that order from third-party suppliers, Nordik manufactures our own windows at our Ottawa facility and our own doors in Hamilton . That means the measurements taken in your home go directly to our production teams—removing the middleman and eliminating potential errors.

As we mentioned in Step 2, every Nordik window and door starts with precise measurements taken in your home. Those measurements don’t just sit in a file—they go straight to our own factories, where your order is custom-built just for you.
Unlike many other replacement companies that source products from third-party manufacturers, we control the entire production process. We make our own windows in Ottawa and our own doors in Hamilton, using materials and technology designed for our climate. That means you’re not getting an off-the-shelf product—you’re getting something created specifically to perform in your home.

We use a combination of factory-trained installers and carefully selected contractors who meet our high standards. Because Nordik has established itself as a leader in the GTA and Hamilton, we’re able to recruit the very best installation teams—specialists who take pride in their work. These teams are exclusive to Nordik, meaning they don’t split their time with other companies. Their expertise is dedicated entirely to our customers.
