About This Site

Approved Window Sales is a small reference site about residential replacement windows in the United States — how window performance is measured and certified, what replacement projects tend to cost and why, and how the contracting process works from first quote to final walkthrough.

It is written for homeowners who are considering a window project and want to understand the subject before sitting across the table from a salesperson. The guides stick to what the governing bodies in this industry actually publish: the National Fenestration Rating Council for performance labels, ENERGY STAR for efficiency criteria, the EPA for renovation rules in older homes, and the FTC for contractor-hiring guidance. Where a page makes a claim that leans on one of those sources, it links to it directly.

An honest note on what this site is not: it is reviewed reference material, not professional advice. It cannot see your house, your climate, or your contract. Pricing figures here are rough national magnitudes for planning, not quotes. For decisions about your specific project — structural questions, lead-safe work in an older home, tax matters — rely on licensed contractors, certified renovators, and tax professionals, not a website.

There are no sponsored products or paid placements in the guides.
