Choices to weigh up in Coseley

uPVC bi-fold doors

uPVC bi-folds cost less than aluminium and insulate well, but the frames are chunkier and the maximum panel size is smaller. They work best on openings up to about three metres wide. White, grey and woodgrain finishes are available, and they can be matched to existing uPVC windows on the same wall.

Widening an opening

Turning a window into doors, or making an opening wider, means cutting the wall and fitting a new lintel or steel beam sized by a structural engineer. Building control must approve the structural work. We organise the calculations, temporary supports, steel and making good, and show these costs on their own lines in your quote.
