What types of windows and doors do you install?
Why should I choose double-glazed windows?
Double-glazing improves your home’s energy efficiency, reduces outside noise and improves security. It also helps maintain a consistent indoor temperature, which can reduce your energy costs.
Do I need to prepare my home before installation?
Yes, we recommend clearing areas around windows and doors and removing obstacles to allow our installers easy access. We take care to protect your home during the installation process.
How do I maintain my new windows and doors?
Do you offer a warranty?
Yes. All products and installations are backed by a comprehensive 10-year guarantee, giving you peace of mind for years to come.
