Customer Reviews
The skylights have transformed our kitchen
Getting rid of those old yellow PVC panels was the best decision we made. The skylights have transformed our kitchen from dark and depressing to bright and airy. The installation team was tidy and professional throughout.

We felt confident with Multitrades Windows & Doors
From the very first consultation, we felt confident in choosing Multitrades Windows & Doors. The Schüco systems they installed are absolutely stunning — smooth, solid, and really elevate the design of our home. The team was incredibly professional, punctual, and paid attention to every detail. A first-class job from start to finish.

Beautiful and Authentic
You would hardly know these aren’t the original timber sashes. They look beautiful and authentic, but the difference in warmth and noise is incredible. Our terraced house is so much quieter now, and no more draughts. The installation team was respectful of our period home and left everything spotless.
Mr T

New Windows and Doors
I have nothing but praise for my new windows and doors supplied and fitted by Multitrades. From the initial showroom visit to the surveying and on to installation nothing was too much trouble.
The doors and windows themselves are top quality and have transformed the house. The fitting team let us know which area they would work day by day to minimise disruption and left the site clean and tidy. The house has a warmer feel to it and has attracted numerous comments from neighbours, one of whom I have passed on my recommendation. Friendly people to deal with, a good job done and all at a competitive price! Many thanks!

The quality is outstanding
The fully glazed Schüco door and matching windows have completely transformed our porch. It’s now bright, welcoming, and feels like a proper entrance to our Stanmore home. The quality is outstanding, and the thermal performance is excellent. The installation team was professional and meticulous throughout. Highly recommended.

The best work I’ve had on site
The best work I’ve had on site. The Schüco windows and skylight installation was completed to an exceptional standard — precise, clean, and completely hassle-free. The attention to detail was outstanding, and the end result has completely transformed the space. The team from Multitrades Windows & Doors were punctual, professional, and clearly experienced. I wouldn’t hesitate to use them again.

New Bedroom Window
We needed a new bedroom window for a guest bedroom. My wife and I were impressed with initial attention and services and the price. With no hitches your fitter and window appeared, the old wooden window frame was removed and the new one fitted with no fuss. Our thanks and appreciation, with best wishes.

Everything was completed to a high standard
We are extremely happy with our new uPVC windows. The house feels much warmer, and the outside noise has been significantly reduced. The installation team was professional, efficient, and respectful throughout the process. Everything was completed to a high standard, and the finish looks excellent. Highly recommended!

The door opens up perfectly onto the garden
The new aluminium French door and windows have completely transformed our home. The door opens up perfectly onto the garden, and the matching windows create a beautiful, cohesive look. The slim frames let in so much light, and the quality is outstanding. The house is warmer, quieter, and looks absolutely stunning. The installation team was professional, tidy, and a pleasure to deal with. Highly recommended.

Frequently asked questions
The main differences lie in wall construction, roof design, glazing proportions and overall architectural appearance. Conservatories typically have predominantly glazed walls and roofs, while orangeries usually combine solid wall sections with large windows and a roof lantern.
Neither is universally better. The right choice depends on your property, intended use, budget and preferred design. An orangery may suit a kitchen-diner extension, while a conservatory may be ideal for a garden room or relaxation space.
Thermal comfort depends on the whole building design, insulation, glazing, ventilation, orientation and heating rather than the name of the extension alone. Both conservatories and orangeries can be comfortable year-round when properly specified.
A conservatory may have a lower starting cost in some cases, but specification, size, structural work and finishes can change the comparison. A high-specification conservatory can cost more than a simple orangery.
With suitable glazing, roof specification, ventilation, shading and heating, a conservatory can be used for much of the year. Modern glass roofs and solar-control glazing improve year-round usability.
Roof lanterns are a characteristic feature of many orangeries, but designs vary. The final configuration depends on the architectural approach and the homeowner’s preferences.
Yes, aluminium is a suitable option for many designs, subject to the selected system and project requirements. Aluminium offers slim sightlines and a contemporary appearance.
Yes. Modern uPVC systems offer design flexibility, low maintenance and appropriate thermal performance. uPVC is available in a range of colours and finishes beyond basic white.
Absolutely. In many ways they are more secure than traditional doors. There are no external key cylinders to pick or snap, access is encrypted, and you can monitor all entry events. Our Schüco systems achieve RC2 security ratings, offering robust protection against forced entry.
Maintenance is minimal. Wipe down frames with a mild soapy solution, lubricate hinges and tracks annually with a silicone‑based spray, and check that drainage channels are clear. The factory‑applied powder coating does not need repainting.
A high-quality aluminium door system, like those from Schüco, can last 40-45 years or more with minimal care. The aluminium itself does not degrade, and the powder-coated finishes are designed to withstand decades of UK weather without fading, peeling, or corroding.
Yes. Schüco doors can be equipped with biometric, keypad, or smartphone access systems for modern convenience.
Yes. Schüco’s advanced modular systems, particularly those built on the AD UP platform, support barrier-free living. We can supply and install doors with a fully flush, zero-threshold threshold, creating a seamless transition between inside and out that is ideal for wheelchair users, pushchairs, and simply reducing trip hazards.
Absolutely. The clean lines of our aluminium casement windows are perfect for contemporary homes, while our uPVC and timber-aluminium composite options can be tailored with traditional details and colours to sympathetically enhance period properties.
Schüco systems are inherently secure thanks to multi‑point locking, anti‑lift devices, toughened glass and robust aluminium frames. When specified, they can meet PAS 24 and Secured by Design standards, providing a very high level of protection against intrusion.
The installation itself is surprisingly fast. Once any preparatory work on your flat roof is complete, our specialist team can often install the lantern roof in just 1-2 days.
Lead times vary by design and specifications, but typically range from 4–8 weeks including installation.
Neither is universally better. Bi-fold doors are ideal if you want the widest possible physical opening and flexible ventilation. Sliding doors are ideal if you prioritise uninterrupted views, large glass panels, and a minimalist aesthetic. The right choice depends on your priorities and your property.
Triple glazing offers superior thermal and acoustic performance compared with double glazing. It’s worth considering for noisy locations, homes aiming for maximum energy efficiency, or properties with large glazed areas. However, it isn’t necessary for every property — a well-specified double-glazed window is more than adequate for many homes.
Smart front doors combine high-performance door construction with electronic, biometric, or wireless technology to control locking and unlocking. They can be operated via smartphone apps, fingerprints, or remote access systems.
In most cases, no. Installing a roof lantern on an existing flat roof typically falls under “Permitted Development” rights. If it’s part of a new extension, it’s usually covered by the (often-permitted) extension plans. We can provide advice on this during our survey, but we always recommend checking with your local authority.
Absolutely. We provide 10-year product guarantees and a comprehensive installation warranty.
Sliding patio doors are usually made of two large glass panels, which open by sliding one panel behind the other. Sliding doors provide easy access to gardens and patios.
No, they are very low maintenance. An occasional clean with warm soapy water is all that is usually needed to keep frames looking their best. They do not require painting or special treatments like timber windows.
We provide a comprehensive, insurance-backed guarantee covering the door slab, frame, hardware, and installation, giving you complete peace of mind. Please ask for full details during your consultation.
Traditional panelled doors, part-glazed doors with decorative glass, and modern doors designed to replicate classic timber styles are often suitable for traditional properties.
A solid, level base (like a concrete foundation or an existing patio) is essential. While we specialise in the supply and installation of the conservatory structure itself, we can project manage the entire build and work with trusted groundworkers to prepare the base for you.
2,090mm (6ft 8″) in height and 1,790mm (5ft 8″) in width is the average size for a patio door.
