How Covefix Works
Three kinds of pages
Guides are written by Adham and follow one fixed structure: a quick answer, a tool list with prices, numbered steps with the expected result of each, a time and cost table, the mechanism behind the fix, and the mistakes that ruin it. Drafting tools help, and a person checks every step, price, and claim before it goes live. Details are in the editorial policy.
Data pages are generated from public datasets: first freeze dates by city and home product recalls. No one retypes the numbers, so no one can mistype them. The page shows its source, and the snapshot date is on the page.
Glossary pages define the parts and terms the guides use, each with its own photo and a link to the fixes that mention it.
Where the data comes from
| What | Source | License | Refreshed |
|---|---|---|---|
| First and last freeze dates | NOAA NCEI U.S. Climate Normals 1991 to 2020, one weather station per city | U.S. government, public domain | Snapshot 2026-10-13. Normals update every 10 years. |
| Product recalls | U.S. Consumer Product Safety Commission recall API | U.S. government, public domain | Snapshot 2026-10-13. Rerun before each deploy. |
| Photos | Wikimedia Commons and Openverse | CC0, public domain, or CC BY and CC BY-SA with the credit shown next to the photo | Per article |
| Part and term definitions | Written for Covefix, checked against manufacturer documentation | Covefix | When a fix or part changes |
How the freeze dates are made
NOAA publishes, for each weather station, the date by which there is a 10, 50, and 90 percent chance that the first fall freeze (a low of 32°F or colder) has already happened, computed from 30 years of daily lows. We show those dates as published. "Finish winterizing by" is the 10 percent date, the earliest freeze that happens in about one year out of ten. The other dates on a city page are counted back from it: furnace test two weeks earlier, gutters and gaps four weeks earlier.
Cities come from a list of large metro areas, each mapped to the station at its main airport. A city is left out when a freeze is not likely in most years (Miami, Honolulu, Los Angeles, San Diego). The station can sit 5 to 10 miles from your street, and a valley or a hilltop can run a week off. Treat the date as a planning date and watch the forecast.
How the recall lists are made
We query the CPSC recall API for the product types this site fixes (water heaters, appliances, furnaces and heaters, electrical products, smoke and CO alarms), keep recalls announced since 2016, and drop results that only match a word, like hair dryers or off-road vehicles. Each entry links to the original CPSC notice, which is the authority on affected models and the free remedy. A recall missing from our list can still exist at CPSC, so search your model number there too.
What we do not do
- We do not sell repairs, parts, or leads. Some product links are Amazon affiliate links, marked with ↗ and disclosed on every page that has them. They never decide what a guide recommends.
- We do not invent local data. If we have no source for a city, the page does not exist.
- We do not publish a data page that adds nothing beyond the source. Each one turns a table into a dated action list and links to the guide that does the work.
Report a mistake
A wrong date, a recall that does not belong, a step that did not work: tell us. Corrections update the page and, for guides, the visible "Updated" date.
