Window Replacement Lab is an independent editorial site about window
    replacement: what an installed window costs, how insert and full-frame work
    differ, and how to read a window quote. We are not a dealer, an installer or
    a manufacturer.

## What we publish

- Cost guides with the unit, labour, removal and trim lines separated.

- A [cost calculator](/calculator/) that prices those components against your own window count.

- Method guides that explain what insert, full-frame and each frame material actually do.

- Problem guides that start with the symptom and the likely cause, not the product.

- Comparisons decided on cost per year of service, not sticker price.

## How we work

- Published price bands and code documents before marketing copy.

- Ranges, not fake precision: a band states what it includes.

- Estimates labelled as estimates; no invented test results or review scores.

- Affiliate links disclosed; placement never follows commission.

- The calculator runs entirely in the browser and sends nothing anywhere.

      *
      Every price band starts with an opening, measured at three points.

      *
      Insert work keeps this frame. Full-frame work removes it.

      *
      A casement costs more than a slider: the hardware is the reason.

      *
      Impact units carry laminated glass and a heavier frame.

## Who writes it

    *

      **Rafael Mendes**

Editor of record. Writes the cost and method guides and maintains the price bands.

    The editor of record is **Rafael Mendes**. The desk is small and
    not a contractor. Every article lists its sources, and every estimate shows
    its arithmetic. The [editorial team page](/authors/) sets out who
    writes the guides and how a page is checked before it publishes.

## What we do not do

    We do not install, sell or manufacture windows, and we do not act as a
    contractor or a home inspector. A structural opening, a failed header or
    water entering a wall assembly needs a licensed professional on site — our
    role is to explain the options and what they should cost.
