How to choose reliable european windows
A plastic window is a complex structure with many hidden elements, and its quality depends on a set of factors:

Competent measurement
High-quality components (profile, fittings, seals, double-glazed Windows, mounting materials)
High-quality construction Assembly (window manufacturing)
Proper installation
In order for the window to serve for a long time and flawlessly, it is the entire complex as a whole that is important. The absence of one or more of the above components will eventually lead to a deterioration in the performance properties of the window and the buyer's disappointment.

Are there any rules for choosing a good window? Much has been said and written about this. We have summarized many years of experience and prepared a window selection algorithm for You.

Choosing a manufacturing company
First, contact your friends, whose opinion you trust. If they are happy with their Windows, service, and conditions - this is the best recommendation, so you can invite a measurer.
Search for information on the Internet, read forums, go to the sites of profile manufacturers and window companies, make a list of those companies whose reviews and information you liked the most and start calling them.
In the process of calling, filter out those organizations where you were contacted impolitely, could not answer questions, or simply did not pick up the phone. If you like the consultation over the phone, order the departure of the measurer (engineer).
Be prepared for the fact that the prices you will find out on the phone are approximate! Each window is made on the individual sizes , the price depends on the size and design color, the number of folds, the thickness of the glazing, method of opening, the availability of additional functions, material used to build Your home and so on. The exact price will be known only after the measurer visits Your home and makes accurate measurements and calculations.

Pay attention to the competence of the measurer: did he ask You questions, did he offer any options for window designs, did he explain what you can't save on, and what you can save on?
Wait for the cost of Windows to be calculated.
Visit the offices of the companies whose offers you liked the most. Before ordering, look and touch the samples, talk to consultants. If the office and its employees evoked positive emotions, then go to the next point.
You just need to choose the most interesting option for you and sign a contract with the company. You did everything right: you conducted a real marketing research and chose the right people.
Pay close attention to the contract: it should clearly and clearly state the company's warranty obligations, specify the terms and cost of not only Windows, but also works, and specify the company's details. This is a guarantee of the manufacturer's integrity and responsibility to the customer. Remember-reliable companies value their reputation!
