Customer Reviews
We were so impressed
We were so impressed with how authentic the new sash windows look. They’ve kept the character of our Victorian home but added all the modern benefits we needed. The house feels warmer, quieter, and much easier to maintain. The Multitrades team were professional, polite, and completed the work to a very high standard.

The difference in our living room is night and day
From start to finish, the team was professional and respectful of our home. We were nervous about cutting a larger opening for the Schuco door, but the installers made it look easy. The difference in our living room is night and day. It’s quieter (we live near a main road), warmer, and frankly, the door looks stunning. Our neighbour is already asking for a quote.

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.
Modern aluminium windows are highly energy-efficient. They incorporate thermal breaks—insulating sections within the frame—which, combined with high-performance glazing, provide excellent thermal performance.
While the initial investment for Schüco aluminium is higher than standard uPVC, it offers superior long-term value. Aluminium is significantly more durable, requires less maintenance, and has a much longer lifespan. Furthermore, the exceptional thermal efficiency leads to lower energy bills, and the prestige of the Schüco brand can increase the resale value of your property.
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.
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.
Yes. To meet building regulations and ensure adequate background ventilation, we can integrate almost invisible trickle vents into the window head.
The timeline can vary depending on the complexity and size of your order. During your initial consultation, we will provide you with an estimated timeline from survey to final installation. Because we control the entire process, we can often offer more reliable and efficient lead times.
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.
Quality aluminium sliding doors can be specified with multi-point locking and robust hardware. Security features vary by product and configuration, so it is important to choose a reputable system and professional installation.
All systems come with a highly secure locking mechanism, and we can install up to 8 panes of glass in our bi-fold doors.
The initial investment for aluminium doors is higher than for standard uPVC. However, they offer far greater longevity, a premium aesthetic, better performance, and require no maintenance costs (like repainting). Over their lifetime, they represent excellent value and can significantly enhance property value.
If you are replacing existing doors, you won’t usually need planning permission to add bi-fold doors. However, if you live in a conservation area you may need to get further information from your local council before going ahead. If you plan to build an extension and add bi-fold doors it’s always best to check local building regulations before you start work.
Very little. A regular wipe down with warm soapy water and a soft cloth is usually sufficient. Avoid abrasive cleaners that could damage the finish.
Flush-fit windows have a sash that closes level with the outer frame, creating a smooth, continuous surface. This mimics the appearance of traditional timber joinery and suits both period and contemporary properties. They are a popular alternative to standard casement windows for homeowners seeking a more refined look.
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.
A glass roof is significantly quieter than a polycarbonate roof. The solid, insulated units muffle the sound of rain, creating a much more peaceful and usable space.
Bi-Fold Doors help light to open up spaces and brighten up your home. This generally makes your home look more desirable which can potenitally add value if you ever choose to sale. Having easy access to a lovely garden or patio area is also a selling point that buyers like to see.
Modern uPVC windows can incorporate multi-point locking, high-security handles, reinforced frames, and laminated or toughened glass. PAS 24 certification provides independent assurance of enhanced security. No window is completely burglar-proof, but a well-specified modern uPVC window offers a high level of protection.
Maintenance is minimal. A simple wipe-down of the frames with a soft cloth and mild, non-abrasive detergent a few times a year is all that is needed to keep them looking pristine. The high-quality hardware may benefit from occasional lubrication.
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).
