JanelaCerta.pt is an independent website that explains windows in plain words.
We do not make or install windows. We do not sell brands either. We explain how to choose, how to compare quotes and what to ask of whoever installs.
If you wish, leave your name and mobile number. We call you, answer your questions and pass your request on to installers in your area. They are the ones who send you quotes.
For you, the service is free and carries no commitment.
We try to write only what is useful and easy to understand. When we are not sure about something, we say so and point to where you can check. The decision and the contract are always yours, with the installer you choose.
