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!

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.
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.
Our manufacturing capabilities encompass over 150 RAL colours with finishes including matte, satin, gloss, textured, and metallic effects. Wood-effect finishes convincingly replicate timber aesthetics without associated maintenance burdens. Dual-colour options allow different interior and exterior finishes—perhaps anthracite grey externally with white internally to complement interior décor.
Lead times vary by design and specifications, but typically range from 4–8 weeks including installation.
A standard installation is usually completed within half a day by our professional teams, ensuring a swift and hassle-free process.
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.
Yes. Schüco profiles are engineered to span wide openings up to several metres in width, with individual panels capable of reaching heights of 3 metres or more. The robust aluminium frames and heavy‑duty running gear handle the extra weight of large panes of glass without distorting.
Installation time varies depending on the door type, property construction, and any necessary adjustments. A straightforward replacement can often be completed within a day, while more complex installations may take longer. A professional installer can provide a more accurate timeframe after assessment.
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.
With proper care, a high-quality composite door from Multitrades has a life expectancy of over 30 years, maintaining its performance and appearance throughout.
Most uPVC front door installations are completed within 1 day, including removal of the old door and full cleanup.
With modern, acoustically optimised double glazing, the sound of rain is significantly dampened and is often described as a gentle, soothing patter rather than a loud noise.
Lead times can vary depending on the complexity of the project and current material availability. However, as a manufacturer and installer, we have direct control over the supply chain. After your initial consultation and survey, we will provide you with a clear and accurate timeline for your specific project.
Yes. The high-density foam core provides excellent thermal insulation, significantly reducing heat loss. Many composite doors achieve U-values as low as 1.1 W/m²K.
The timeline varies but typically takes several weeks. This allows for manufacturing and careful scheduling. We will provide you with a clear timeline upon order.
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.
Yes. Tilt and turn windows are particularly well-suited to upper floors and apartments. The tilt function provides secure ventilation without a large opening, and the turn function allows full access for cleaning from inside. They are also a safer option for homes with young children.
Generally, yes. Three panes and two insulating cavities usually reduce heat loss more than two panes and one cavity. However, the actual difference depends on the complete window system – frame, glazing specification, spacers, seals and installation – not just the number of panes.
Flush sash windows offer a sleek, contemporary look where the sash sits flush with the outer frame. They are particularly popular for traditional and heritage homes, as they replicate the clean lines of timber windows while providing modern performance.
High-quality uPVC windows have a life expectancy of 30-35 years or more. They are incredibly durable and are backed by extensive guarantees, which we are proud to offer on our products and installation.
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.
