Suburbs we cover here: Lambton Gardens, Cinderella, Lambton, Sunnyridge
Knights is built around the rail sidings, with freight handling, transport yards and warehousing that runs to the timetable rather than to office hours.
What we see in Knights
Impact is the operating environment here, not a maintenance failure. Sooner or later a forklift or a trailer finds the curtain, and the question is whether the door was built so that is a bottom rail replacement or a full recurtain.
We build for repairability as much as strength: replaceable bottom sections, standard slat profiles we hold in stock, and guides bolted so they can be swapped without cutting into the structure.
Getting on site
Industrial sites run their own induction, permits and traffic rules and we work to them. We confirm site access, whether hot work is permitted and what the bay can be taken out of service for before committing to a date, because a loading bay closed unexpectedly costs far more than the door. Where the work has to happen outside production hours we schedule it that way and price it that way from the start.
Motors, backup and load shedding
Industrial doors need industrial gear. We spec three-phase where the supply allows and heavy-duty single-phase where it does not, with a control box rated for the environment rather than a domestic unit in a steel enclosure. Every install gets a manual override that a shift supervisor can operate without a technician, because at two in the morning that is the difference between a delay and a stoppage.
Repairs on any make
We repair any make, and on industrial doors that usually means getting the bay working first and doing the proper repair second. We carry common slat profiles, bearings and bottom rails, so an impact is often a same-day fix rather than a week waiting for parts. Where a door is genuinely at end of life we will say so and quote a replacement built to the duty cycle the bay actually runs.
What it costs
We quote Knights jobs off a free measured survey, itemised so you can see what the door, the motor and the installation each cost, and fixed in writing before anything is manufactured. We do not quote a range over the phone and then adjust it on site, because that is not a price, it is a deposit.
How soon we can be there
Surveys in Knights are normally within one working day and the quote follows the same day the survey is done. Manufacture depends on the door, and we give you a real date rather than an optimistic one. Breakdowns are attended same-day wherever we can reach you.
Getting a quote
Send us the opening, or ask for a survey and we will come and measure it. Either way you get an itemised written price for your Knights door, valid as quoted, with no charge for the visit.

Common questions
Roller doors in Knights
Not if it was built properly. On our industrial doors the bottom rail and individual slat sections are replaceable, so an impact is usually a same-day repair rather than a full recurtain. We hold the common profiles, bearings and rails. If you have been told the entire curtain must be replaced, it is worth a second opinion before you spend it.
Yes, and on most Knights sites that is the sensible way to do it. A bay out of service during production costs far more than the door, so we schedule around your shift pattern and price it that way from the start. We also work to site induction, permits and traffic rules and confirm all of it before committing to a date.
Almost always that the door was specified for a lighter duty than the opening actually runs. A unit rated for domestic or light commercial use will not survive the cycle count of a working Knights opening, and the motor is simply the part that shows it first. We ask what the door does per day and spec the motor and barrel to that, which costs a little more once and stops it recurring.
