Window Fix Path.
Windows, Tested From the Sill Up — every product bought at retail price and tested in real homes. No sponsored verdicts, no recycled spec sheets.
How It All Started
In 2023, founder Tomás watched his heating bill climb every winter while cold air poured off his old windows. Every product he tried promised “draft-proof,” and almost none delivered.
So he started Window Fix Path — buying the seal, repair, and upgrade products himself, testing each one through a full Pacific Northwest season, and publishing the honest score. No affiliate fluff, just what survives.
Today we’re a small team in Seattle with a workshop full of windows in every stage of repair — more than 25 products tested and re-tested yearly.
What We Stand For
Four promises we’ve kept since day one.
Bought, Not Borrowed
Every product is purchased at retail price with our own money. Review units from brands are declined or clearly marked.
Tested in Real Homes
Installed, used, leaked on, and climbed over. If it can’t survive a real fix, it doesn’t score well.
One Honest Verdict
Each product gets one score out of 10 with the trade-offs stated plainly. We never take payment for a good score. Read our Disclosure.
Re-Tested Yearly
Home products change fast. We re-review every product every year and update scores when better options appear.
