Who we are

Gaster Aluminium provides the services you need. We work with skilled workforce in all specialties and trades to ensure that your project is completed on time and within budget.

Aluminium doors are great options because there are so many choices. Aluminium folding doors, including aluminium bi-fold doors, are perfect for larger openings and those that require an unusual configuration while aluminium sliding doors are a more simple choice indoors or outside. These doors are as beautiful as they are functional and available in options such as French doors and other attractive designs.

Whether you have already decided on aluminium for certain home elements, or you are still in the decision-making process, Gaster Aluminium is your premium resource for quality aluminum products and great information.

Aluminium architecture is now a more affordable and fashionable solution. There are many other benefits as well: Aluminium is durable, easy to clean and is much stronger – making them the premier solution for use in areas with heavy wind, rain or other natural elements that can destroy traditional wood frame windows. Aluminium products are also attractive, with many style options available for your property.

With decades of experience, Gaster Aluminium employs SAGGA union glaziers to install our finished products. Our supervisors are integral to the planning, site logistics and staging of the material. By incorporating this knowledge and experience we continually strive to deliver the highest standard of service. Beginning with pre-construction budgeting and design assistance, through to the professional installation of windows, entrances, storefronts and curtain wall.

Whether you want to update your building, office or residential tower window glass or door glass, add a glass feature or accent to your wall or fix damaged doors and other glass related building problems.
