🔧 Binding or difficult operation

Doors and windows should open and close smoothly. Binding, stiffness or increased resistance may indicate dirt within the mechanism, poor alignment, worn components or excessive load on the operating system.


🛠️ Noisy or clunky movement


Grinding, scraping, clicking or knocking noises should not be ignored. These sounds can indicate worn rollers, hinges, guides or other moving components.


🔧 Sliding doors rubbing


A sliding door that rubs against its frame, track or threshold may have dropped out of alignment or developed problems with its rollers. Continuing to force the door can cause further damage.


🛠️Bi-fold doors dropping


Dropped or uneven bi-fold doors can become difficult to operate and may no longer close or lock correctly. Adjustment or replacement components may be required.


🔧 Misalignment


Uneven gaps, catching edges and doors that no longer sit squarely within the frame are common signs of misalignment. This can affect operation, security and weather resistance.


🛠️ Locks becoming difficult to operate


A stiff lock or handle may be caused by misalignment rather than the lock itself. Forcing it can damage the locking mechanism, handles or associated components.


🔧 Water ingress or draughts


Leaks and draughts may indicate failed seals, blocked drainage, movement within the system or poor adjustment. The source should be identified before damage spreads to surrounding finishes.


🛠️ Cracked or failed glazing


Cracked glass, misted sealed units or damaged glazing seals require professional inspection. The correct repair will depend on the glass specification, framing system and cause of the failure.


🔧 What to do next


Avoid forcing a door or window that has become difficult to operate. Photograph the affected area, note any noises or changes in movement, and arrange an inspection before the problem worsens.
