It feels like a natural extension of the living space
The new aluminium French door has completely transformed our flat. The terrace now feels like a natural extension of the living space, and the door opens beautifully. The flat is warmer, quieter, and looks absolutely stunning. The installation team was professional, tidy, and a pleasure to deal with. Highly recommended.

Very professional, quick and tidy
The new patio doors and windows have completely transformed the back of our house. We love how much brighter it feels inside, and the smooth sliding doors make garden access so much easier. The Multitrades team did an excellent job — very professional, quick, and tidy throughout.
Mr P. K.

Absolutely stunning
The Schüco entrance door is absolutely stunning. It feels incredibly solid, the security features give us peace of mind, and the thermal performance is outstanding. Our hallway is so much warmer now, and the door looks beautiful against our Windsor home. The installation team was professional, respectful, and the finish is flawless. Highly recommended.

The quality of the aluminium bi-fold door is superb
The quality of the aluminium bi-fold door is superb. It completely transformed our extension. It folds away neatly, and we can now enjoy the garden from the sofa. The installation team was professional and tidy from start to finish. Highly recommended.

Our New Windows Completely Modernised the House
The anthracite grey windows look fantastic and have completely modernised the house. The installation team were professional, tidy, and completed the work to a very high standard. We’re extremely happy with the result.
Mr D

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!

We’re absolutely delighted
We’re absolutely delighted with our new French doors. They’ve brightened up our kitchen and made such a difference in how we use the garden space. The quality of the Schüco system is outstanding, and the installation team from Multitrades were efficient, respectful, and very tidy. A fantastic service from start to finish!

The difference in comfort is night and day
You can barely tell they aren’t the original timber sashes, but the difference in comfort is night and day. The flat is warmer, quieter, and we finally feel secure. The team was respectful of our period home and left everything spotless.

Frequently asked questions
Consider replacing your front door when you notice persistent draughts, difficulty opening or closing, rot or warping, damaged seals, outdated locks, or if the door no longer suits your property’s appearance. A professional assessment can help determine whether repair or replacement is the better option.
For many homeowners, yes. A modern replacement can improve thermal insulation, security, kerb appeal, and reduce maintenance requirements. The long-term benefits often outweigh the initial investment.
Each material has its strengths. Composite doors offer a good balance of security, thermal performance, and traditional aesthetics. Aluminium doors provide slim sightlines and a contemporary look. uPVC doors are practical, low-maintenance, and cost-effective. The best choice depends on your priorities and property style.
Modern front doors typically incorporate advanced multi-point locking systems, stronger frames, and robust construction, which can enhance security compared to older wooden doors with basic locks.
A modern replacement door with good insulation, effective seals, and quality glazing can reduce heat loss through the entrance, potentially lowering heating demand. Actual performance depends on the specific door system and installation.
Traditional panelled doors, part-glazed doors with decorative glass, and modern doors designed to replicate classic timber styles are often suitable for traditional properties.
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.
Yes, options such as SafeGuard app and fingerprint access are available on certain smart door models, where supported. These features offer convenient and modern access control.
Our roofs are engineered with a sophisticated, integrated drainage system and high-performance seals. Combined with our expert installation, this ensures a completely watertight structure.
Absolutely. While “Brilliant White” remains a classic choice, we offer a wide range ofRAL colours and woodgrain foils. Our most popular contemporary options include Anthracite Grey and Black, while our wood-effect finishes (like Irish Oak) provide the look of real timber without the maintenance.
You can choose from over 200 RAL colours in a matt, satin or gloss powder‑coat finish. Anodised metallic effects, textured finishes and dual‑colour options (different colours inside and out) are also available. We can match most architectural colour schemes.
Yes, typically. The significant brick walls and solid sections of the roof provide much better insulation than a fully glazed conservatory, making it easier and more cost-effective to heat all year round.
Yes. Builders, architects and developers can open a trade account with us. We offer supply-only on very competitive terms, complete with technical drawings, structural calculations and dedicated account management.
Not if it’s designed and built correctly. Modern conservatories with energy-efficient double glazing, thermal breaks in the frames, and options like thermal roof systems or solar control glass are designed for year-round comfort. We can also integrate ventilation and blinds to perfectly manage the temperature.
The price varies significantly based on size, configuration, material (aluminium vs. uPVC), and glazing choice. A small uPVC 2-panel kitchen window will be a fraction of the cost of a large 4-panel aluminium system. We offer competitive pricing and will provide a precise, no-obligation quote based on your specifications.
In most cases, rooflights fall under “Permitted Development” and do not require planning permission, provided they do not protrude more than 150mm from the roof plane. However, rules can differ in conservation areas or for listed buildings. We can advise you on this during our consultation.
Absolutely. Composite doors are available in a huge range of colours, finishes, glazing options and hardware styles. Whether you prefer traditional or contemporary, there’s a door to match your taste.
With proper installation and care, quality uPVC windows can last 20–30 years or more. Many manufacturers offer guarantees of 10 years or longer, reflecting the durability of modern materials and construction.
Yes. Aluminium’s strength makes it the ideal material for large-span openings. We can manufacture and install expansive sliding and bifold door systems with minimal supporting框架, creating breath-taking, seamless transitions to your garden or terrace.
Most uPVC front door installations are completed within 1 day, including removal of the old door and full cleanup.
They are ideal. Children can gain entry with a simple fingerprint without the responsibility of carrying a key. You can let them in remotely after school, and you always know who has come and gone.
2,090mm (6ft 8″) in height and 1,790mm (5ft 8″) in width is the average size for a patio door.
Extremely efficient. Thanks to the “thermal break” technology—a polyamide barrier separating the interior and exterior aluminium—they prevent heat transfer. Systems like the Schüco ASE 80 sliding door can achieve U-values as low as 0.99 W/m²K, which meets the rigorous Passive House standard. This keeps your home warm in winter and cool in summer.
Absolutely. The strength of the aluminium allows for impressively large door leafs, creating a wide, inviting entrance.
A popular combination is a lantern glass roof over the dining or island area and aluminium bi-fold or sliding doors opening to the garden. This floods the space with light from above and the rear, creating a bright, social heart of the home.
Yes. Not only do they reduce your home’s energy consumption (lowering your carbon footprint), but modern uPVC is also fully recyclable. At Multitrades Windows & Doors, we are committed to sustainable practices.
A single handle controls both functions. The first turn opens the window in the tilt position. The second turn allows the window to swing open inwards.
Schüco smart systems are designed to integrate with broader smart home platforms, allowing your door to work in concert with lighting, alarms, and heating. Our team can advise on compatibility with your existing setup.
