Frequently asked
How quickly can you survey a site?
We typically complete site surveys within 3-5 working days of enquiry. Urgent surveys for emergency or time-sensitive projects can often be arranged within 24-48 hours.
What information do you need for a quote?
Site address, scope of work, any specifications or drawings, access requirements, and preferred timing. Photos are helpful for repair enquiries.
What are typical lead times for new installations?
Standard installations are typically 4-6 weeks from order. Complex or large projects may take longer. Emergency and reactive work is prioritised accordingly.
Are you FENSA registered?
Yes, we are FENSA registered for all relevant installations, meaning you receive certification and building control notification as part of the service.
What accreditations do you hold?
We hold CHAS, Constructionline Gold, and are FENSA registered. Our team includes DBS-checked engineers for work in sensitive environments.
Can you provide RAMS and method statements?
Yes, we provide full RAMS documentation for all commercial projects as standard. We're experienced in main contractor requirements and site protocols.
How do you decide between repair and replacement?
We assess condition, cost-effectiveness, and availability of parts. We'll always give you honest advice on whether repair makes economic sense or replacement is the better long-term option.
Can you repair doors from any manufacturer?
We repair most commercial door systems and carry parts for common brands. If specialist parts are needed, we can usually source them within a few days.
Do you repair automatic doors?
Yes, we service and repair automatic swing, sliding and revolving doors from most manufacturers including GEZE, ASSA ABLOY, DORMA and Record.
Do you charge for call-outs?
If we can't fix it, you don't pay. Standard reactive call-outs include a diagnostic visit — if we repair on the spot with parts we carry, you pay the repair cost only. If parts need ordering, we provide a fixed-price quote before any further work.
How do you price planned maintenance contracts?
Contracts are priced based on asset quantity, visit frequency, and scope. We'll survey your sites and provide a clear annual or quarterly cost.
Do you provide written quotes?
Yes — every job over a basic repair receives a written, itemised quote with no hidden extras. Quotes are valid for 30 days.
Can you work outside trading hours?
Yes, we regularly complete installations and repairs during evenings, weekends and overnight to minimise disruption to your operations.
How do you minimise disruption in live buildings?
We plan work carefully around your operations, use dust sheets and barriers, maintain safe access routes, and clean up thoroughly. Our teams are experienced in occupied building protocols.
Are your engineers DBS checked?
Yes, our engineers are DBS checked and we can provide certificates for work in schools, healthcare and other sensitive environments.
