Why choose Alteza Aluminium windows and doors? End-to-end service & 10 years of warranty

September 28, 2026

Choosing aluminium windows and doors involves more than selecting a design. Accurate measurements, proper fabrication, and careful installation all affect the finished product. When different teams handle these stages, keeping the work aligned can become difficult.

Alteza provides aluminium window and door solutions with one team handling the project from the initial requirement onwards. Customers can discuss their needs, select the required specifications, and have the systems made and installed through the same service.

Here is what customers can expect when they choose Alteza for their window and door requirements.

Why Choose Alteza Aluminium Windows and Doors?

The material, components, and workmanship all contribute to the finished window or door. Alteza aluminium windows and doors are made of premium-quality material, original hardware, quality glazing and reliable components for its systems.

The products can be customised to suit the requirements of a project. Size, style, glazing, colour, finish, hardware and other accessories can be discussed during the planning stage. Fabrication is carried out using German technology and supported by skilled workmanship.

The service also stays connected through a single point of contact and one technical and customer service team. Customers can therefore work with one team across the different stages instead of coordinating each requirement separately.

From Design to Post-Sale Service: Our 5-Step Process

A window or door system passes through several stages before it becomes part of a finished space. Alteza manages these stages as one process, beginning with the project requirements and continuing after installation.

1. Design Consultation & Survey

The process starts with a one-on-one consultation and site survey. Alteza begins by understanding the project requirements early, whether the requirement is for a single window or a larger project.

The discussion covers the details that will shape the finished system, including size, style, configuration, glazing, colour, finish, hardware and mesh. Site measurements are taken to establish the specifications needed for fabrication.

Customisation is also considered at this stage. Different glass options, colours, finishes and hardware can be discussed according to the requirements of the project. This gives the fabrication team a clear specification to work from once the design is finalised.

2. Fabrication

After the specifications are established, fabrication begins. Alteza uses premium-quality aluminium along with original branded components, quality glazing and reliable, proven hardware.

The fabrication process uses German technology and careful workmanship. The different parts of the system are prepared according to the approved design and measurements, including the aluminium profiles, glazing and hardware.

Attention to these details is important because the finished product needs to match the requirements established during the consultation. Once fabrication is complete, each window or door is prepared for delivery to the project site.

3. Delivery

The finished products need to be protected between the fabrication facility and the project site. Alteza individually wraps and packs each product to reduce the risk of damage during transit.

The premium aluminium window and door systems are then delivered according to the agreed schedule. Careful packing and planned delivery help ensure that the fabricated windows and doors reach the site ready for installation.

4. Installation

The work does not stop when the products reach the site. Alteza’s installation team handles the fitting process and pays attention to alignment during installation. Any minor alignment issues that need to be addressed during fitting are handled by the installation team. 

Once the windows and doors are installed, they are checked before handover. The team inspects the joints, channels, hardware, and glazing and tests the newly installed systems.

These checks help confirm that the windows and doors have been fitted correctly and are functioning as intended before the project is handed over.

5. Post-Sale Service

The relationship with the customer continues after installation. Alteza’s customer support team remains available to address functional issues with the installed systems.

The company provides free service for functional issues during the first 12 months after installation. This gives customers a defined support channel during the initial period of use.

Post-sale service therefore forms the final stage of the process rather than ending the relationship at installation.

What to Expect When You Choose Alteza?

Customers can configure their aluminium window and door solutions according to the project requirements and receive warranty coverage after installation.

Customisation for Different Project Requirements

With Alteza, aluminium doors and windows can be customised to suit different project requirements. Customers can select the size, style, glazing, colour, finish, hardware and mesh configuration.

The range includes different glass options, including double glazing, along with options for taller windows and doors. Colour choices include silver, champagne, bronze and black.

These options allow the systems to be planned around the requirements of the space rather than relying only on fixed specifications.

10-Year Warranty for Long-Term Assurance

We provide a 10-year warranty on our products. The warranty is part of the company’s commitment to product quality and installation standards.

The warranty and post-sale service serve different purposes. Functional issues are covered under free service for the first 12 months after installation, while the 10-year warranty provides longer coverage for the products.

Conclusion

The right aluminium doors and windows should fit the way a project is designed, built and used. With the right specifications and a clear understanding of the project requirements, customers can plan their windows and doors with greater clarity from the start.
