Anyone building a house or furnishing an apartment will at some point face the necessity of buying or replacing windows. This doesn't have to be a major source of stress – you just need to remember a few important rules. In this article, we advise on what to pay attention to and what mistakes not to make, so you can enjoy warm, functional, and beautiful joinery for longer.
Mistake No. 1: Price as the most important criterion
Yes – purchasing a set of windows, doors, gates, and coverings for a house is a significant expense.
But is it worth replacing windows out of necessity and spending twice as much when, after a few years, they start to deform, lose their airtightness, or fade? Higher prices from reputable manufacturers are justified by a number of measurable quality indicators, such as: certified raw materials, regular quality tests, or top-class hardware and glazing technology.
It is precisely these that give us confidence that the purchased product will serve us flawlessly and maintain its parameters regardless of the conditions.
Mistake No. 2: Improper installation and lack of professional measurements
Professionally performed window installation (in an ideal scenario – by the manufacturer's representatives) is the best way to maintain the warranty, enjoy a perfectly leveled, evenly installed product, and achieve maximum comfort of use for the system. It is also worth considering the so-called warm installation with a multi-layer sealing system.
Improper installation of the structure exposes us to a number of inconveniences, such as leaks, moisture penetration, drafts, mold formation, rubbing of elements, or improper sash mechanics.
Mistake 3: Compromises due to appearance
Sometimes it happens that an investor visually likes a specific product, which doesn't quite fit the project's specifics or requirements.
For example: no wooden window can offer us the same resistance to long-term, harsh weather conditions as aluminum. Therefore, in such a case, we recommend choosing a matte colour from the RAL palette in a more natural shade, which allows you to maintain the desired effect without compromising the required parameter.
There are many such examples. It is always worth trusting a specialist's recommendations or finding a safe alternative together.
Mistake 4: Failure to consider the building's technical conditions
Every house has its own specifics. This means different requirements for thermal insulation, noise protection, or wind load resistance, which is why not all windows will work – even those that are "recommended" or "bestselling".
Choosing joinery without considering the investment's location (e.g., places with large temperature differences, strong winds, or near a busy street) can result in faster product wear, reduced indoor comfort, and loss of technical properties.
That is why it is so important to match system parameters to actual climatic conditions, local law, and building requirements.
Mistake No. 5: Ignoring service and warranty issues
We usually focus mainly on the appearance, advantages of the window, and its price, but we sometimes forget about an equally important factor: after-sales service.
Meanwhile, regular service and the availability of spare parts are of immense importance for the durability of joinery! For example, what if we can't quickly replace a seal in winter, or our specialist won't be available for another month?
By choosing a manufacturer with a comprehensive service offering and clear warranty terms, we gain confidence that any potential malfunctions will be quickly and professionally rectified – without additional stress.
