Weather seals & bottom sealThree things most homeowners never hear about their door
It is the heaviest thing in your house that moves every day. A few plain facts explain almost every service call we get.
The opener does not lift the door. The springs do. The motor only guides a load the springs already carry, which is why a door that suddenly feels impossibly heavy is a spring problem and not a motor problem.
Springs are rated in cycles, not years. The springs commonly supplied on the market have a service life of about 10,000 cycles, which door manufacturer Garaga puts at over 13 years at two openings a day. Four openings a day halves that.
A torsion spring is the one repair to never do yourself. The door and access systems trade association is blunt about it: DASMA TDS-171 says spring replacement "should only be performed by a trained door systems technician."

Answers, with the source printed beside them
Six questions homeowners ask us constantly. Every number on these pages comes from a technical standard or a municipality, and the document is linked next to the claim so you can check it.
