Know what you are replacing.
The visible door is only one part of the decision. Tracks, hardware, the opener and the available clearances also need consideration. Keeping an existing opener may be possible in some projects, but suitability should be checked against the new door rather than assumed. Tell us about past repairs, any recurring faults and what you would like to improve in daily use.
An opportunity to improve the fit.
Replacing a door is a useful time to reconsider the profile, colour and access controls together. Think about how the garage relates to the main entrance and whether the current door makes the frontage feel too busy or too plain. Inside, consider storage, lighting and vehicle clearance. Changes to the door type may affect the installation requirements, so a like-for-like measurement is not always the whole story.
