Committed to quality across survey, supply and installation.
Astragal works with homeowners, designers and builders across south west London to specify doors and windows that fit the building and the brief.
How we work
Clear advice before manufacture. Careful installation on site.
The right window or door system starts with the opening, not the catalogue. We focus on proportion, thermal performance, access, threshold detail and finish so the final result feels settled.
- Specification support for aluminium and timber systems.
- Measured surveys before ordering or manufacture.
- Installation focused on alignment, weathering and finish.
- Advice that respects period character and modern performance.
