Electric Roller Garage Doors

JLM Doors supplies and installs electric roller garage doors designed to provide security, convenience and a clean modern appearance. Roller doors are particularly useful where customers want to maximise space inside the garage, as the door rolls vertically into a compact canopy rather than swinging outwards.

Installations can include insulated 77mm laths, electric operation, remote controls, safety edges, canopy covers, brush and rubber seals and optional battery backup. Each door is measured and specified to suit the individual opening and property.

Garage Door Repairs

JLM Doors provides garage door repairs for customers with faulty, damaged or poorly operating doors. Where an existing door can be repaired, the team can assess the problem and advise on the most practical solution. If a door is beyond economical repair, replacement options can also be discussed.

Repair services are available for domestic and commercial garage doors, helping customers restore safe and reliable operation without automatically replacing the complete system.

Garage Door Servicing & Upgrades

Regular garage door servicing can help identify developing problems and keep electric doors operating smoothly. JLM Doors can service existing installations and advise on upgrades where customers want to improve operation, security or convenience.

Insulated Garage Doors

For garages connected to the home or used as workshops and storage areas, an insulated roller garage door can help reduce draughts and improve comfort. The insulated lath construction, combined with brush and rubber seals, provides a more substantial replacement for many older garage doors.

Commercial & Industrial Doors

Alongside residential installations, JLM Doors works with commercial and industrial garage doors and roller shutters. Solutions are available for workshops, warehouses, business premises and other sites requiring secure and practical access.
