Problems we repair
From a jammed doorset to a complete overhaul.
Pro-Lock regularly assesses fractured hinges, worn or disconnected rollers, dragging or dropped panels, threshold and header catches, closure and locking faults, damaged tracks and hardware, failed seals, and draughts. Toe and heel is one important area checked when appropriate: manufacturer-specific glazing packers positioned at diagonally opposite corners of the glass help keep the sash square and level, supporting smooth movement and, where relevant, lock alignment.
Movement and alignment
Hinges, rollers, dropped panels, misalignment, and doors that drag or catch. Toe and heel is checked when appropriate as one part of the alignment picture.
Closure and security
Difficult closing or locking, plus faulty locks, cylinders, handles, keeps, and catches.
Tracks and weather seals
Worn tracks and hardware, failed seals, draughts, rattles, and poor contact.
Complete overhauls
A complete doorset overhaul is a repair option used when frame distortion is beyond the manufacturer’s tolerances and/or panel realignment cannot compensate for the degree of frame distortion. It can include structural repairs where the frame is distorted, but not every complete overhaul requires structural frame repair.
Why do you charge £79 for an assessment when some companies offer free quotes?
Pro-Lock checks the complete doorset and aims to return it to operation as intended by the manufacturer, rather than treating only the immediate symptom. This helps prevent unnecessary stress transferring to mechanical components, reduces the cycle of repeat repairs, and maximises long-term reliability and service life. Your assessment is carried out by an experienced engineer, not a salesman. We complete an in-depth assessment of all aspects of your bifold doorset, talk you through the findings while we are on site, and provide the information in the report that accompanies the quotation for any repairs recommended. The £79 professional assessment visit lasts 45 to 60 minutes. No repair work is carried out during the assessment. The report and itemised quotation then follow by email, so you can understand the findings and options before deciding whether to proceed. If you choose to go ahead with the repair, the £79 assessment fee is credited against the repair cost, so you do not pay for the assessment in addition to the repair. The fee is also refunded if suitable parts are unavailable and we cannot provide a quote, or if the doorset is considered beyond economical repair. All work carried out is backed by our market-leading 12 month warranty, covering our workmanship and any parts supplied and fitted as part of the repair where applicable. Payment is only taken after satisfactory completion of the agreed repair work.
