Frequently asked questions

Why are torsion springs dangerous?
A standard residential garage door spring stores 50,000+ ft-lbs of energy. When it breaks or is mishandled, the recoil can cause severe injuries. Spring replacement is a $200-500 pro job — never DIY this.
Insulated vs non-insulated — when does it matter?
Always insulate if the garage is attached to living space (kitchen, bedroom above). Insulation improves room comfort, reduces HVAC load, and makes the garage usable as workshop/gym.
How long does a garage door last?
Steel doors: 20-30 years. Wood doors: 15-25 years with maintenance. Openers: 12-15 years. Springs: 10,000 cycles (~7-10 years typical).
