Safety first, sources always
A garage door is usually the largest moving object in a home, and garages also hold fuel, chemicals and power tools. Every guide follows official safety guidance and tells you plainly when a job belongs to a trained door technician or a licensed electrician.
- Garage door opener safety from the CPSC and the federal entrapment-protection standard
- Carbon monoxide and fuel safety from the EPA, CDC and NFPA
- Insulation and efficiency data from the U.S. Department of Energy and ENERGY STAR
- Product specifications from manufacturers' own manuals and data sheets
How we check a guide
- Start from official agencies and manufacturer manuals.
- Show the math behind every sizing or coverage number.
- Say plainly what we researched versus tested hands-on.
- Re-check on a schedule, and fix fast when readers report a change.

How we work
Editorial methodology
We cite primary sources, separate fact from opinion, and never claim to have tested something we have only researched.
Affiliate disclosure
We may earn a commission from some links, at no cost to you. Commissions never decide what we recommend or how a tool calculates.
Corrections
Spot something out of date? Tell us and we will check it against the source and log the fix.
Why Basement Playbook exists
Basement Playbook was founded by Jeremy Jarvis to be the garage resource he wanted: clear measurements, honest trade-offs, safety guidance from official sources, and tools that show their work, instead of product roundups that skip the prep, the sizing and the safety.
Frequently asked questions
Is Basement Playbook free to use?
Yes. Every guide and tool on the site is free. We are reader-supported through affiliate commissions, which never change how a calculator works or what it recommends.
Do your calculators store my information?
No. The calculators run entirely in your browser. Nothing you type is saved or sent to us.
Do you test the products you recommend?
We tell you on every review whether we tested a product hands-on or researched it from specifications, manufacturer documentation and independent sources. We never present research as personal testing.
Can I replace a garage door spring myself?
Torsion and extension springs hold a lot of stored energy, and the cables and drums attached to them can cause serious injuries. We recommend a trained garage door technician for spring and cable work.
Where should I start with a garage makeover?
Clear and measure first, fix anything unsafe, then do the floor before storage goes on the walls. Our free Garage Makeover Plan Builder puts the steps in order for your goals in about two minutes.
