About | Window Replacement Lab

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 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.

An installer measuring a window opening before a replacement — Every price band starts with an opening, measured at three points.

A double-hung window with its lower sash open in a timber frame — Insert work keeps this frame. Full-frame work removes it.

A casement window with its crank hardware visible, opened into the room — A casement costs more than a slider: the hardware is the reason.

Impact-rated windows installed in a coastal home — 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 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.
