    — Frequently asked

    Entrance Doors FAQs

    Do you install aluminium and glass entrance doors?

    Yes, we specialise in commercial aluminium entrance doors and frameless glass entrance doors for offices, retail, schools, gyms and managed buildings across London, Kent, Essex and Surrey. We supply and install swing doors, pivot doors, automatic sliding doors and glazed lobby systems.

    Can you repair entrance doors that scrape, drop or don't latch properly?

    Absolutely. Door alignment issues, sagging and latching problems are very common in high-traffic commercial doors. Our engineers diagnose the cause—whether it's worn pivots, failed floor springs, or misaligned frames—and carry out professional repairs to restore smooth operation.

    Can you replace failed glazing units in entrance door screens?

    Yes, we replace failed double-glazed units in aluminium door frames and side screens. We match existing glass specifications for thermal performance and appearance, and can upgrade to toughened safety glass or enhanced security glazing where required.

    Do you upgrade pivots, hinges, closers, locks and handles?

    Yes, hardware upgrades are one of our core services. We replace worn floor springs, overhead closers, pivot sets, handles, locks and panic hardware. We use quality components from brands like GEZE, Dorma and ASSA ABLOY to ensure longevity in demanding commercial environments.

    Do you support access control and mag lock coordination?

    Yes, we regularly install entrance doors that integrate with access control systems, mag locks, intercoms and automatic openers. We coordinate with your security contractor or can recommend trusted partners for a complete access control solution.

    Do you offer planned maintenance for high-traffic entrance doors?

    Yes, we provide planned preventive maintenance (PPM) contracts for commercial entrance doors. Regular servicing extends hardware life, maintains smooth operation and helps you budget predictably rather than facing unexpected repair costs.

    How fast can you attend reactive call-outs for entrance door problems?

    For urgent issues affecting security or accessibility, we typically attend within 2-4 hours across London and the South East. Non-urgent repairs are usually scheduled within 1-2 working days. Our 24/7 emergency line covers out-of-hours call-outs.

    What information do you need to provide a quote for entrance doors?

    For the most accurate quote, we need: site address, number and size of doors, preferred frame colour (RAL reference if matching existing), glazing requirements, hardware specifications, and any access control integration needs. Photos are very helpful for repair enquiries.

    What are your typical lead times for new entrance door installations?

    Standard entrance door installations typically take 4-6 weeks from order to completion. This includes manufacture of bespoke aluminium frames to your specifications. Urgent projects can sometimes be fast-tracked—please discuss your timescales with us.

    Can you work outside business hours to avoid disruption?

    Yes, we regularly complete entrance door installations during evenings, weekends and overnight to minimise disruption to your operations. Out-of-hours work is priced at the same rates as standard hours—no premium charges.

    Do you provide RAMS and method statements for commercial sites?

    Yes, we provide full RAMS documentation for all commercial projects as standard. Our team is experienced in main contractor protocols, site inductions and working in live building environments with appropriate safety measures.

    Are your engineers DBS checked for work in schools and healthcare?

    Yes, our engineers are DBS checked and we can provide certificates for work in schools, colleges, NHS facilities, care homes and other sensitive environments where safeguarding is required.

    What areas do you cover for entrance door services?

    We cover London and the South East including Kent, Essex, Surrey, Sussex and surrounding areas. Our main coverage includes Greater London, Dartford, Gravesend, Bromley, Croydon, Sevenoaks, Maidstone, Chelmsford, Basildon, Guildford and all areas in between.

    Can you match existing door frames and colours?

    Yes, we can match existing aluminium frames in any RAL colour, plus match glazing specifications and hardware styles. This is important for partial replacements or additions to existing entrance lobbies.

    Do you install automatic entrance doors?

    Yes, we supply and install automatic swing and sliding entrance doors from leading manufacturers. This includes low-energy options for accessibility compliance, sensor activation, push button control and integration with access control systems.

    How do you handle make-safe and emergency entrance door repairs?

    Our 24/7 emergency team responds rapidly to damaged entrance doors. We board and secure the opening, then coordinate fast-track glazing and hardware replacement to minimise the time your entrance is out of service. We provide full documentation for insurance claims.
