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your front door when you notice persistent draughts, difficulty opening or closing, rot or warping, damaged seals, outdated locks, or if the door no longer suits your property’s appearance.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.
Yes, we manufacture and supply high-quality uPVC Tilt & Turn Windows, which offer excellent thermal performance, low maintenance and great value.
Security is a core principle of Schüco engineering. All systems feature multi-point locking mechanisms as standard, along with integrated finger-trap protection and anti-lift devices on sliding doors. The inherent strength of the aluminium profile itself makes it extremely resistant to forced entry, and many systems meet stringent security standards like PAS 24.
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.
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.
Absolutely. In many ways they are more secure than traditional doors. There are no external key cylinders to pick or snap, access is encrypted, and you can monitor all entry events. Our Schüco systems achieve RC2 security ratings, offering robust protection against forced entry.
In most cases, no. Replacing windows usually falls under “Permitted Development.” However, if you live in a Conservation Area or a Listed Building, special rules apply. Our team can advise you on the local requirements during your initial consultation.
Yes. Bi-fold doors are widely used in UK homes, particularly for extensions, kitchen-diners, and garden rooms. They are available in configurations suited to British weather conditions and building regulations.
Yes, they are highly energy-efficient. With modern frames and advanced double or triple glazing, they can significantly reduce heat loss from your home.
Not with modern technology. This was a common problem with old polycarbonate or basic glass. We use high-performance solar control and thermally efficient glass to ensure your room remains at a comfortable temperature all year round.
Both materials can look stunning. Aluminium offers ultra-slim frames favoured in minimalist designs, while premium uPVC now offers slim profiles and a vast range of colours and finishes that rival aluminium. The choice often comes down to budget and specific design preferences.
Absolutely. While known for modern designs, aluminium doors are incredibly versatile. We offer a range of classic colours (like heritage greens and greys) and even wood-effect finishes. The slim sightlines can be designed to complement traditional architecture, offering improved performance without compromising character.
Yes. Aluminium door systems are typically made to measure to suit the specific opening and design requirements of each property.
Yes. Eurocell uPVC is a fully recyclable material, and the exceptional energy efficiency of the windows helps to reduce your carbon footprint by lowering heating costs.
Absolutely. In many ways they are more secure than traditional doors. There are no external key cylinders to pick or snap, access is encrypted, and you can monitor all entry events. Our Schüco systems achieve RC2 security ratings, offering robust protection against forced entry.
Schüco offer standard and bespoke aluminium glazing solutions, their range of products include windows, doors, facade glazing, blast and fire-resistant systems as well as purpose-designed glazing.
A smart front door is an entrance door that incorporates electronic, biometric, or wireless technology to control locking. It can be opened by fingerprint, smartphone, or app, removing the need for traditional keys and allowing remote access management.
Absolutely. The strength of the aluminium allows for impressively large door leafs, creating a wide, inviting entrance.
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.
A thermal roof (or solid roof) is an advanced alternative to traditional polycarbonate panels. It is insulated like a regular house roof, making the conservatory cooler in summer and warmer in winter. It’s an excellent choice if you plan to use the room as a full-time living space, like a kitchen or lounge.
We can supply with double or triple glazing, with options for self-cleaning glass, solar control, acoustic insulation, or decorative stained glass to match your home’s style.
