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.
L.T.
in Woodford Green
First-class work
The new white aluminium windows and door look absolutely correct for our period Belgravia home, but the performance is light years ahead of the old steel units. The house is warmer, quieter, and the door feels wonderfully secure. The installation team was meticulous and respectful of our property. First-class work.
Mr E

Glide like butter
The Schuco bi-fold doors are absolutely stunning. They glide like butter, and the slim frames make the garden feel like part of the room. The installation team was meticulous and left everything spotless. Worth every penny for the quality.

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your front door when you notice persistent draughts, difficulty opening or closing, rot or warping, damaged seals, outdated locks, or if the door no longer suits your property’s appearance.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.
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.
Yes. Aluminium door systems are typically made to measure to suit the specific opening and design requirements of each property.
Beyond classic white, we offer a extensive palette of colours, including Chartwell Green, Anthracite Grey, and Black, as well as dual-colour options (e.g., white on the inside, a colour on the outside).
Both our aluminium and uPVC bi-fold windows are incredibly low-maintenance. The frames simply need an occasional wipe with soapy water to keep them clean. The moving track and hinges should be kept free of debris and lightly lubricated annually to ensure years of smooth, flawless operation.
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.
Not when installed correctly. The key is in the design and installation. Our lanterns are designed with effective drainage channels and we use high-quality seals. Combined with our expert installation, we guarantee a completely watertight finish.
Yes, this is one of their greatest strengths. The structural rigidity of aluminium allows it to support very large, heavy glazing units, making it the ideal choice for expansive picture windows and glazed façades.
The main difference between patio doors and french doors is the way they open. Patio doors slide along a track and open to the side, whereas french doors open outwards. Patio doors are more modern in appearance and therefore best suited to a modern contemporary property, whereas french doors lend themselves to more period and heritage properties.
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.
In most cases, no. Conservatories often fall under “Permitted Development Rights.” However, this is subject to certain limits and conditions (e.g., size, height, and location). As part of our service, Multitrades Windows & Doors will advise you on this and ensure your project is fully compliant with building regulations where required.
Minimal maintenance is required. A simple clean with mild soapy water a couple of times a year is all that’s needed to keep the frames and glass looking new. There is no need for sanding, painting, or sealing.
-
uPVC is a cost-effective, low-maintenance, and thermally efficient option, great for a classic look and excellent insulation.
-
Aluminium offers a sleeker, more modern appearance with slimmer frames for maximum light. It is incredibly strong, durable, and low-maintenance, ideal for larger, more contemporary designs.
Our team can guide you on the best material for your home, budget, and vision.
Schüco aluminium windows offer superior strength, allowing for much slimmer frames and larger glass areas than uPVC. They are significantly more durable and weather-resistant than timber, requiring virtually no maintenance while offering a much longer lifespan.
Depending on how they’re installed, made and cared for, double glazing windows can last between 10-50 years. They should last for at least 20 years minimum.
Aluminium doors offer superior strength with much slimmer frames, allowing for larger glass panels and more natural light. They are more durable and weather-resistant than uPVC, require far less maintenance than timber, and offer a more contemporary, high-end aesthetic. Their longevity and thermal performance with modern thermal breaks also make them a cost-effective long-term investment.
Absolutely. Schüco offers an extensive palette of over 200 colours and finishes. You can choose from standard RAL colours, metallic effects, anodized finishes, or even realistic timber-effect foils. You can even specify different colours for the inside and outside of the door to match your interior décor and exterior facade perfectly.
The cost varies significantly based on size, materials, and complexity. As a guide, a uPVC orangery starts from a higher investment than a standard conservatory due to its solid construction. We provide clear, fixed-price quotes after our initial survey so you know exactly what to expect.
Absolutely. All our glass roofs are made to measure. We manufacture in Britain, so we can cater to unusual dimensions, specific pitch angles and non-standard shapes without compromise.
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.
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.
