Why Ausma
We work with established brands and our own fixed crew of installers — not rotating subcontractors.
High-quality materials
PVC, aluminium and timber window frames from brands like Schüco and Veka — not an unbranded budget line.



Clean installation
Our own installers fit every frame and pane themselves, with an eye for weatherproofing and finish.
Clear communication
You know the cost and the date upfront — and we stick to it.
Tailored to the project
From a single pane to a full facade renovation: the approach fits your situation, not the other way round.
Our approach
We believe in clear communication, a clean installation and work you will still be happy with in the long run.
Getting acquainted
We listen to the situation and wishes and determine which solution best suits the home, project or building.
Clear agreements
Clarity up front: you know where you stand on price, planning and execution. No surprises afterwards.
A hands-on approach
From first contact to completion, we keep communication short and stay involved throughout the project.
A clean result
We work towards a clean handover with attention to installation, finish and the overall picture.
Sustainability
HR++ and HR+++ glass lower your energy bill and improve comfort — often with financial support available.
HR++ and HR+++ glass insulate considerably better than single or older double glazing.
For home energy upgrades, subsidy or financing options are sometimes available — we're happy to help you check.
Replacing glass and frames together saves on installation costs compared to two separate projects.
