Thomas Sanderson awning repairs and servicing, independent specialists since 1998

SBI Ltd are independent awning specialists, not connected to Thomas Sanderson. We have carried out awning repairs, servicing, recovering, safety inspections and chemical cleaning on Thomas Sanderson awnings across England and Wales for many years, and it is the make we are asked about more than any other.

If you own a Thomas Sanderson awning and it has stopped working, won’t retract, has a torn cover or has never been serviced, we can help.

If you need Thomas Sanderson awning repairs near you, start with photographs and your postcode. We will confirm whether we can help and what travel applies before anything is booked.

Get your awning identified, send three photographs

The complete awning from the front; the cassette from the side; and the remote control, wall switch, motor label or any sensors. If you still have the original paperwork (order form, invoice or guarantee), photograph that too and send it with your pictures, as it often tells us the exact model straight away. That is enough for us to identify the likely model, check whether parts are available and tell you the next step before any visit is booked. We may ask for two more, the arms and the brackets, once we know what we are looking at.

“Had my awning serviced by SBI Ltd. It was installed about 20 years ago. It now looks like new again. Excellent service. Very Pleased. Would highly recommend.”

If your awning is stuck open right now

  • Stop operating the awning. A motor straining against a jammed arm can do further damage.
  • Keep people away from beneath it, especially in wind.
  • Do not climb up to it, dismantle it, tie it down or force it closed. Call us for advice.

A Customer Solutions Manager will talk you through what is safe to do for your awning and your situation. Please only carry out any step we suggest if you can do so safely; steps taken on our telephone advice are at your own risk, and SBI Ltd cannot be held responsible for actions taken without us on site.

  • Arm failure, a sheared arm on a Thomas Sanderson Sorrento; the fault that takes most older awnings out of service.

If your awning is coming away from the wall

  • Stop using it. Do not stand underneath it.
  • Do not try to re-tighten the brackets yourself from a ladder.
  • Call us for advice. We will tell you what is safe to do until someone can inspect the fixings and brackets on site.

How the free photo assessment works

We start with a free photo assessment. In most cases, that lets us identify the awning, check likely parts availability and give you a written quotation before we visit, without charging you for a survey. A survey is only needed where the photographs cannot settle it. This may be an unusual installation, a commercial site, or an awning we cannot identify from the profile. Either way, you will know the price before anything is booked.

The faults we see most on Thomas Sanderson awnings

This is the most common motor fault we are asked about. Thomas Sanderson awning motors are sealed units, so we do not repair the original motor. On older awnings we normally replace it with a current Somfy unit. A clicking, buzzing or grinding noise with little or no movement usually points the same way: stop using the awning and send photographs rather than running the motor against a jam. A replacement motor fitted by SBI Ltd carries a five-year warranty on the motor itself; replacement remotes and sensors carry a two-year warranty.

That is the wind sensor, a small wireless vibration sensor in the front bar on most premium models, with its own battery. We replace it rather than assume it works; on a twenty-year-old awning, it is often the sensor and the motor that get replaced, since both are out of warranty and waiting to fail. Bear in mind that if the motor fails, an awning without a manual override will be stuck wherever it is, often fully extended.

Arm failure is what takes most older awnings out of service. Where the arm type is still made, we replace arms in pairs so both sides carry the same tension. If it’s no longer made, we say so.

We can recover most Thomas Sanderson awnings with a new commercial-quality cover, supplied and fitted, the old cover removed. A cover on its own rarely makes sense on an awning with a failing motor or arms, which is why we look at the whole awning first.

Usually repairable; occasionally the parts have gone. Tell us what you have, and we will check.

Most of the Thomas Sanderson awnings we see are between ten and twenty-five years old and have never been touched. A service is usually the best money you can spend on one.

Which Thomas Sanderson awning do you have?

Thomas Sanderson sold a range of models over the years, and the name on your paperwork tells us a great deal. If you have the original order or guarantee, photograph it and send it with your pictures. If you don’t, the side-on profile of the cassette is the fingerprint we use to identify it. Most Thomas Sanderson awnings were not made by Thomas Sanderson: they were sold and installed under that name but manufactured by premium European awning makers, which is why parts are still obtainable for many of them.

 

Model Originally made by Parts
Monaco / Monaco Niteline Weinor (Opal Design II) Parts generally available
Milano / Milano Grande Weinor (I2000 / K2000) Parts generally available
Geneva / Geneva Lumière, piston arms Markilux (1500 / 1550) Piston arms no longer obtainable; a failed piston arm means a replacement awning
Geneva, later spring arms Markilux (1600 / 1650) Current model, serviceable
Ultima / Ultima Shadeline / Ultima Niteline Markilux (6000) Current model, serviceable. The Shadeline adds a drop valance; the Niteline adds lighting
Sorrento Weinor (CAP, discontinued) Arms still obtainable, serviceable
Nexus / Nexus Deluxe Thomas Sanderson Only the motor and controls can be replaced; no other parts are available

Milano and Milano Grande. An angular, squarer cassette. We identify these as the Weinor I, K or N 2000 family. Well made, and among the models we can most often keep going.

Geneva and Geneva Lumière. The Lumière carries integral lights. Geneva awnings were fitted with two arm types over the years: an earlier piston arm (the 1500) and a later spring arm (the 1600). The piston arms were superseded some years ago, and replacement pistons are no longer obtainable, so if a piston has failed, the only option is a replacement awning. We will tell you before you spend anything.

Nexus and Nexus Deluxe. A popular premium model, often fitted with Somfy motors and wind and sun sensors, and frequently with heaters and integral lights. On the Nexus and Nexus Deluxe, the only parts we can replace are the motor and controls, so we diagnose carefully before recommending a repair.

Ultima, Ultima Shadeline and Ultima Niteline. Full cassette models. The Shadeline is the Ultima with a drop valance, and the Niteline is the Ultima with lighting. The Shadeline paperwork sometimes describes the cassette as a Monaco, so send the paperwork if you have it.

Can you still get Thomas Sanderson awning parts?

Sometimes yes, sometimes no, and we will always tell you which before you commit. For many models, particularly the Weinor-built Monaco and Milano families, arms, motors, controls and covers are still obtainable. For some older components, such as Geneva piston arms, they are not, and on the Nexus and Nexus Deluxe the only parts we can replace are the motor and controls.

Where parts are no longer made, we will say so plainly, offer to make the awning safe, and, if you wish, give you a price for a modern replacement that we can support for years to come. We don’t spend your money on an awning that cannot be kept going unless you ask us to, understanding that it is a gamble; that is your prerogative, and we’ll be honest before you decide.

Is an old Thomas Sanderson awning worth repairing?

Usually. These were premium installations. Many customers tell us they paid £3,000 to £3,500 twenty years ago, which puts them in the Rolls-Royce or Bentley class of awning, and a like-for-like replacement today, a German-built full cassette with motor, sensors and lights and bespoke brackets can exceed £10,000 once it is sized and specified properly.

If the frame, arms, and fixings remain sound and compatible parts are available, a service, a new motor, or a new cover is generally far more economical than replacing the whole awning. We assess that before recommending any work. Replacement prices depend on the survey and vary with size and specification.

What a Thomas Sanderson awning service includes

Minimum service visit: from £1,194 including VAT (£995 plus VAT)

Includes:

  • A full safety inspection of the awning, its fixings and brackets.
  • A full service of the mechanism and controls, with lubrication, pitch adjustment and new batteries in the remote and wind sensor where applicable.
  • A clean of the frame.
  • A chemical clean of the cover and valance.

Travel: included across Greater London, Kent, Surrey, Sussex, Essex, Hertfordshire, Berkshire and Buckinghamshire. For longer distances, we confirm the cost in writing from your postcode before booking.

Not included: replacement motors, remotes, sensors, arms, covers, lights and heaters. We quote these separately in writing based on your photographs, so you know the full cost before we come and decide before anything is ordered.

In almost every case we send a two-person crew. It is our normal practice for safety, with one operative footing the ladder while the other works. The visit is a service, not a repair: apart from small jobs that can be done with what is already there, such as taking off or refitting an existing valance, replacement parts are not fitted on the day.

Why people with Thomas Sanderson awnings come to us

Because their original supplier could not help, or because a local company would not touch an awning it had not installed. Many of our Thomas Sanderson customers come by word of mouth, and a good number tell us they were recommended to us by Thomas Sanderson themselves.

We have 400+ five-star Google reviews, we are members of the British Blind and Shutter Association, and we have been doing this since 1998. Our advantage is not the products we sell. It is our ability to diagnose.

Can we help with yours?

We are most likely to be able to help when:

  • The awning is a permanent folding-arm patio awning.
  • You can send photographs and a postcode.
  • You want a professional repair, service or recovering rather than DIY advice.
  • You are comfortable that visits start from £1,194 including VAT.

Thomas Sanderson Awning Repair FAQs

Safety and urgent problems

Call us for advice. Do not try to force, climb on or tie down the awning yourself. Keep everyone clear of it and telephone us; a Customer Solutions Manager will talk you through what is safe to do in your situation. Only carry out any steps we suggest over the phone if you can do so safely, and do so at your own risk.

Stop using it and keep clear. Do not climb up to tighten brackets yourself. Call us for advice; we will talk you through what is safe until the fixings can be inspected on site.

Most often, it’s the motor, a wind sensor, or a failed arm. Stop using it, keep clear, and send photographs; in most cases, we can tell you what’s wrong from the pictures.

Often the motor is straining, or an arm or mechanism has jammed. Stop operating it, keep clear, and send photographs so we can advise before further damage.

Motors, remotes and parts

Yes, on most models. The motors are sealed units, so we replace them rather than repair them. We fit a current Somfy motor and programme the controls.

Yes. Power at the plug does not mean the motor, receiver, remote or sensor is sound. Send photographs of the awning, the controls and the motor label if you can see it, any original paperwork (order form, invoice or guarantee), plus your postcode. We will tell you the likely next step before any visit is booked.

We offer a five-year warranty on a replacement motor, covering the motor itself. Replacement remotes and sensors carry a two-year warranty. New arms fitted by SBI Ltd carry a five-year SBI Ltd warranty in normal use. It does not cover storm damage or arms broken by wind or rain.

In most cases, yes. The handset is usually a Somfy. On an older awning we supply and programme a new handset together with a new motor and sensor, rather than pair a new remote to a motor that is already out of warranty; we will explain why when we quote.

We replace arms in pairs where the arm type is still made, so both sides carry the same tension. If it’s no longer made, we’ll let you know.

On the Nexus and Nexus Deluxe, the only parts we can replace are the motor and controls. Send photographs, and we will tell you what that means for yours.

Pricing and coverage

From £1,194 including VAT for a service visit. We quote parts and repairs separately in writing after we review photographs, before we visit.

Travel is included across Greater London, Kent, Surrey, Sussex, Essex, Hertfordshire, Berkshire and Buckinghamshire. Further afield across England and Wales, we may add a travel charge, confirmed in writing from your postcode before booking.

Identifying your awning

SBI Ltd, independent specialists covering England and Wales. We are not connected to Thomas Sanderson.

Usually, yes. Send photographs, and we will identify the model and tell you what can be done.

Yes, with a new commercial-quality cover, provided the frame, arms and motor are worth keeping, which we check first.

From the paperwork if you have it; otherwise from the side profile of the cassette. Send that photograph, and we will do the rest.

Yes, and it is one of the most common reasons people ring us. No paperwork and no remote is not a problem.

Send your photographs as follows:

  • Close-up side of the awning
  • Front of the awning and your property
  • The remote control and any sensors
  • Any original paperwork (order form, invoice or guarantee) and your postcode. It often tells us the exact model straight away.

Send your photos by WhatsApp or email, whichever is easier. We will identify your awning, tell you what it needs, and provide a written quote. Or call our 24-hour enquiry line and leave your details anytime; an SBI Ltd Customer Solutions Manager will call you back.
