How to request window quotes correctly and compare them effectively ?

Choosing new windows is an important investment. Not only do they define the appearance of your home, but they also have a major impact on comfort, insulation and long-term maintenance. Yet many homeowners struggle when requesting and comparing quotations. Prices can vary significantly, details are not always clearly specified, and this makes comparisons difficult. With the right approach, you can avoid unpleasant surprises and make a well-informed decision. These practical tips from Aliplast will help you choose the solution that best suits your home and your needs.​


Prepare your request thoroughly ​

An accurate quotation starts with a clear and detailed request. The more specific your requirements are, the more precise the price calculation will be. 
Consider the following in advance: ​

  • The type of windows (tilt-and-turn windows, sliding windows, fixed, etc.)
  • The desired material
  • Colour and finish
  • Glazing (double, triple, solar control, acoustic, etc.)
  • Optional extras such as ventilation grilles, safety glass, or shading solutions

Aluminium windows offer a major advantage: thanks to their slim profiles and high load-bearing capacity, large glass surfaces are perfectly possible without compromising stability or insulation. Aliplast offers an extensive range of profiles in various styles. Whether you own a contemporary villa, a charming country-style home, or an elegant townhouse, there is always an aluminium profile that perfectly matches your property. At Aliplast, you can also choose from an almost unlimited range of colours and a variety of finishes, including matt, gloss, and textured coatings. Would you like the exterior of your windows to complement your façade while the interior matches your interior design? Then opt for bicolour windows, featuring a different colour on the inside and outside.

 

Request multiple quotations, but make them comparable

It is advisable to request at least three quotations, all based on the same specifications. This is the only way to make a fair and accurate comparison. Avoid vague requests such as “price for new windows” and instead provide a window-by-window overview of your requirements.

Make sure each quote clearly specifies:

  • The exact profile type
  • The thermal insulation values (Uw value)
  • The type of glazing
  • The finish and colour
  • Warranty conditions

Choose a high-quality brand that offers a solid warranty. Windows are exposed to a wide range of weather conditions, including sunlight, rain, hail, and extreme temperatures. That is why it is important to consider the material when selecting your windows, as it largely determines their lifespan. With aluminium windows, you have very little to worry about. They have an average lifespan of 50 to 60 years. Aluminium profiles are highly resistant to corrosion and cracking, offer excellent colour retention, and provide enhanced scratch resistance. Aliplast even offers a colour range backed by a 25-year coating warranty. In addition, this warranty comes with the Qualicoat Seaside quality label, which provides extra protection against aggressive environments such as traffic pollution and coastal conditions. That’s true peace of mind. 

 

Look beyond the price alone

The lowest price is not always the best choice. When comparing quotations, it is important to consider the long-term value as well. Aluminium windows, for example, require minimal maintenance and retain their shape and colour for many years. This means fewer costs and fewer concerns in the long run.

Particular points to consider:

  • Material lifespan
  • Maintenance requirements
  • Installation quality
  • Service and accessibility of the window manufacturer

A car lasts longer when it is regularly maintained, and the same applies to windows. When purchasing new windows, it is important to look beyond the initial purchase price and consider future maintenance costs as well. These costs can add up significantly over time. Make sure you choose wisely: what appears to be the cheapest option at first glance may result in substantial maintenance expenses later on.

With aluminium windows, you make a smart long-term choice. They do not require painting or varnishing and are exceptionally easy to maintain. Depending on your environment, aluminium windows and doors should be cleaned two to four times a year: twice a year is generally sufficient in rural areas, while urban and coastal environments require cleaning around four times a year. To preserve the colour and finish of the aluminium, it is also recommended to treat the profiles once a year. Aliplast offers a range of mild maintenance products for this purpose, available through a dealer near you.

 

Ask for clarification if anything is unclear

Do you find certain terms or price differences difficult to understand? Ask for clarification. A reliable window manufacturer will take the time to explain the quotation and provide transparent information about available options and any additional costs. This may include colour finishes, glazing options, or other customisations.

Clear and comprehensive explanations are often a sign of craftsmanship and good customer service, qualities that are just as important as the product itself. A reputable manufacturer or distributor works with certified systems, has proven experience, and can offer reliable warranties.

 

Conclusion

Requesting and comparing window quotations correctly requires some preparation, but it is always worth the effort. By providing clear specifications, carefully analysing quotations, and looking beyond the price alone, you can make an informed decision that will benefit you for many years to come. Aluminium windows are a particularly strong choice in this regard: they combine aesthetic appeal, durability, and long-term performance, making them a future-proof investment for any home.
