A shop, office, school or surgery door that drags, slams, will not lock or has come off its pivot is a security gap and a safety risk from the moment it fails. We identify the fault from your photo, arrive with the parts and put the door back into service in one visit — usually without closing the premises.
Trusted by big brands
Each door type fails in its own way and takes its own parts. Tell us which you have, or send a photo, and we bring the right hardware first time.
Single and double entrance doors on shops, offices and schools. Dropped leaves, worn pivots and top centres, failed transom closers, locks, keeps and re-glazing.
FramelessPatch-fitted and rail-fitted toughened glass doors on retail units. Floor springs, patch locks, rollers, pivots and replacement panels.
PoweredSliding, swing and bi-parting operators. Sensors, drive belts, rollers, switches and controllers, serviced to BS EN 16005.
SecurityPlant rooms, loading bays, back-of-house and fire exits. Locks, panic bars, hinges, closers and re-hanging of heavy leaves.
ComplianceClosers, intumescent and smoke seals, panic hardware and gaps brought back within tolerance, with the paperwork your fire risk assessor asks for.
HardwareOverhead and concealed closers, floor springs, bottom pivots, handles, hinges, mortice locks and shoot bolts on any of the doors above.
Most commercial door failures announce themselves weeks in advance. These are the symptoms that come through on the phone, and what is usually behind them.
The leaf scrapes the threshold or catches the frame. A worn bottom pivot, a tired floor spring or a failed hinge is letting the door sag; the closer and lock are fighting it.
The closer has lost its hydraulics and the door falls shut. On a school or surgery door that is a finger-trap; on a shop it is broken glass waiting to happen.
A door that has moved on its pivot stops meeting its keep. The lock is usually fine; the alignment is not. Shoot bolts and hook bolts wear the same way.
Impact, a dropped leaf or a seized pivot. We make the opening safe, board if needed and re-glaze with toughened or laminated glass to the right specification.
Dirty or misaligned sensors, worn rollers and belts, or a controller fault. Many are cleared on the first visit without parts.
An entrance abandoned for a side door costs trade and compromises fire escape. We treat these as priority call outs and aim to reopen the door the same day.
A cross-section of recent work, one of each door type, each with photographs and a write-up of the fault and the fix.
Commercial Door Maintenance and Security Ltd is based in the West Midlands and attends commercial premises across mainland UK. The case studies on this site run from Plymouth to York and from Liverpool to London, and the pattern is the same everywhere: a quote from your photo, the parts on the van, and the door back in service in a single visit.
The cities we attend most often each have their own page with local case studies and response times: Birmingham, Bristol, London, Manchester, Liverpool, Nottingham, Coventry, Gloucester and York, with the full list on the locations page.
Multi-site operators — retail chains, dental and optical groups, academy trusts, facilities managers — can put every door on one maintenance contract with a single point of contact and consistent reporting across sites.
One photo of the door, one of the fault or hardware label, a short clip if it moves badly, and the postcode. Send them through the contact page or WhatsApp them to the office number and we come back with a fixed price and an attendance date. Office hours Mon–Sat 8am–10pm, emergency call outs outside those.
Aluminium shopfront and office entrances, frameless and patch-fitted glass doors, automatic sliding and swing doors, steel security and fire exit doors, timber fire doors, bi-fold and sliding terrace doors, and the hardware on all of them: closers, floor springs, pivots, hinges, locks, panic bars and access control. If it is on a commercial building and it swings, slides or folds, we repair it.
Photograph the door, the fault and any hardware labels, add a short clip of the door opening and closing if it is a movement problem, and send them with the site postcode through the contact page. Most faults can be identified from that footage, so we quote the same day with the parts already picked, and the engineer arrives once with everything needed.
Same-day or next-day across most of mainland UK. Doors that will not close, will not lock or have broken glass are treated as priority call outs. The office runs Monday to Saturday, 8am to 10pm, with out-of-hours emergency attendance available.
Rarely. Most hardware repairs are done with the door in place or lifted out for under an hour, and on a pair of doors we work one leaf at a time so the entrance stays open. Where a floor spring or frame section has to come out we book the work for early morning, after trading or a quiet period the client chooses.
Repair wherever the part is sound. A new arm on a working closer, a new pivot under a dropped door or a re-glazed panel is cheaper than a new door and keeps the frame untouched. We replace only what has failed, and tell you which is which before any work starts.
Yes. Parts carry the manufacturer's guarantee and our workmanship is guaranteed, with every job documented in photographs and a written summary of what was found and done, which most clients pass to their insurer or facilities records.
Mainland UK from our West Midlands base: Birmingham, Worcester, Gloucester, Bristol, London, Manchester, Liverpool, Nottingham, York and the towns between. Our case studies show the spread, and the locations pages list the cities we attend most often.
Send a photo and a short description of the fault and we’ll come back with a fixed-price quote the same day. Most diagnoses don’t need a site visit.
A 6-monthly or annual commercial doors service contract catches the failing closer, the worn pivot and the dragging latch before they stop the door. Each visit checks closing and latching speeds, pivots and hinges, locks, seals and fixings, puts right what can be adjusted on the spot and quotes the rest as planned work rather than an emergency call out — with a written record of every door for your insurer and fire risk assessor.
