Methodology

How we judge brands, lanes and product claims.

The goal is not to reward the best rendering. The goal is to reduce buyer regret.

What goes into a guide

We use manufacturer documentation, public pricing when available, official local-code examples, owner reports and repeated buyer objections.

How verdicts are formed

We judge fit and scope. A product can look great and still be wrong if the buyer needs permit support, winter comfort or a company that can service the project locally.

How we use manufacturer replies

Manufacturer replies can correct specs, pricing, lead times and warranty details. They do not buy ranking placement.
