Installation time depends on the number of units and complexity, but many standard window or door replacements are completed in one to two days, while larger projects and full house packages naturally take longer.

During the survey we measure the openings, check surrounding structure, assess access, and talk through your ideas and priorities so we can recommend the most suitable products and configurations.

We will advise on appropriate glass types, safety requirements, and positioning to help ensure your installation complies with relevant building regulations and best practice.
