Customer Reviews
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 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.

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
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.
Yes. We stand by the quality of our workmanship and materials. All our conservatories come with a comprehensive manufacturer’s and installation guarantee, giving you long-term protection and peace of mind. Specific warranty details will be provided with your quotation.
Our bespoke manufacturing process typically delivers within 4-6 weeks from final survey, though this varies with project complexity and current production scheduling. We provide firm lead time commitments during the quotation process.
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.
Absolutely. Aluminium bi-fold doors provide floor-to-ceiling glazing across a wide span, bringing huge amounts of daylight in and enhancing the indoor-outdoor connection. Even when closed, the large glass panels brighten the room.
Yes. New windows improve kerb appeal, energy efficiency, and security — all factors that can enhance a property’s market value. FENSA certification also provides documentation that buyers often look for.
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.
Yes. The slim sightlines and wide range of colours (including heritage tones) allow them to be sympathetically fitted into period homes without compromising on performance.
Yes. Modern aluminium sliding doors incorporate thermal breaks, double or triple glazing and advanced weather seals, vastly outperforming older aluminium or timber patio doors. U-values can be as low as 1.2 W/m²K or better, meeting and exceeding building regulations.
With an average lifespan of 20-35 years, double glazing windows are normally recommended to be no more than every 40 years, but this all depends on the conditions of the windows.
Sliding doors often provide cleaner, more uninterrupted views because they use large single panes with minimal vertical framing. Bi-fold doors also offer excellent views but have more frame divisions due to their hinged panels.
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.
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.
Triple glazing generally raises the internal surface temperature of the glass, which can reduce the risk of condensation forming on the pane. However, condensation is also affected by indoor humidity, ventilation and installation quality.
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.
Not at all! Our uPVC and aluminium windows simply require an occasional wipe down with a damp, soapy cloth to keep them looking like new.
Absolutely. Modern French doors from Multitrades are equipped with high-security multipoint locking systems and robust frames, making them as secure as any modern door.
Not if the glass is correctly specified. Modern solar control glass, low-E coatings and thermally broken aluminium frames limit solar gain and maintain comfortable internal temperatures. Ventilation, such as opening skylights or sliding doors, helps regulate heat naturally.
Our aluminium and uPVC frames are virtually maintenance-free and just need an occasional wipe-down. For the glass, we highly recommend upgrading to self-cleaning glass, which uses a special coating to break down organic dirt and let rainwater wash it away, keeping your view clear for longer.
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.
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.
