When you’ve already purchased your windows and doors, finding a trusted installer can be just as important as choosing the products themselves. Poor installation can lead to draughts, leaks, reduced energy efficiency and costly repairs, even when you’ve invested in premium-quality products.
That’s where Fenex Windows comes in.
Our Installation Only Service is available nationwide, providing expert fitting for homeowners, builders, developers and commercial clients who have sourced their own windows and doors but want the confidence of professional installation.
Whether you’ve ordered bespoke products from a manufacturer, purchased windows through a trade supplier or are managing a self-build project, our experienced installation team is ready to help.
What Is an Installation Only Service?
An Installation Only service means you supply the windows or doors, and Fenex Windows provides the skilled installation.
This is an ideal solution if you’ve:
- Purchased windows or doors directly from a manufacturer.
- Found the perfect products through a trade supplier.
- Ordered bespoke glazing for a renovation or extension.
- Managed your own building project.
- Been let down by an installer and need a reliable team to complete the work.
Our experienced fitters ensure every product is installed safely, accurately and in line with industry best practices.
