Windows are probably the most overlooked part of the house, and people normally don’t really consider ever replacing them. However, there are plenty of signs that scream that it is time to change the windows, and install new ones. One of them is your heating bills going up, because all the heating escapes from the windows which is why it required more energy to keep your house warm. That being said, the window replacement process is a complicated one and one that needs to be taken seriously. So when you are choosing a window company, make sure you keep these things in mind.

1. Knowing what you want

Windows serve a variety of different functions, and it is up to you to know what you need from your windows. You could either want smooth air circulation or you could want a picturesque window that is great for sight seeing. You may want windows that are low maintenance, because windows tend to collect a lot of dust. All these purposes will require different sorts of frames, which will then determine that material and hence your expense.
You should also have in mind the kind of theme you want for your room, and then select the windows accordingly because the windows will definitely draw a lot of attention so you want them to go with the vibe of the whole room. Make sure you know exactly what you want because windows are not exactly cheap, and it will be a shame if you end up not liking them.

2. Knowing the materials to be used

Window frames are usually made from four main materials. These are wood, clad, aluminium and vinyl. Wood is great for aesthetic purposes, and gives a very rich look to the entire room, but it can easily be infested by termites and also tends to be towards the pricier side. Clad windows are aluminium or vinyl coated wood frames and they are light in weight as well as resistant to rust. The most used and cost effective material is vinyl as it is not only durable but also resistant to different types of erosions.

3. Knowing the safety codes

The law requires windows to be large enough to escape from in case of a fire accident. So you should keep that in mind before designing the windows, and you will need a professional contractor to guide you through the right way of choosing a window. It is important that they company you hire is a professional one, and they do a thorough job in installing the windows, since it is usually a one-time thing, and you wont be changing you windows before the next decade.
