What should Harpenden homeowners know about flush sectional doors?
Are flush doors more expensive?
Flush panels are often in the mid or premium tiers of a range, so expect them to cost a little more than an entry-level ribbed door.
Do smooth panels show marks?
Smooth, darker finishes show dust, fingerprints and small dents more readily than ribbed or textured panels. A satin or slightly textured flush finish is more forgiving.
