When buying a property, be sure to check the windows!

Buying a property means viewing many flats and houses before we find the perfect one. Every space needs a careful inspection so that we do not buy the proverbial "pig in a poke". One of the most important elements we must pay attention to when choosing a property is the windows. Their condition determines both proper thermal insulation and how well the interior is soundproofed. And choosing a flat with damaged windows will leave us facing a costly replacement. How can you avoid this? Find out in this article.

When buying a flat, it is definitely worth taking a close look at the windows, so that we do not discover shortly afterwards that we have to replace them at our own expense. Where should we start the inspection?

When the windows were last replaced

First of all, as potential buyers, we have the right to know when the windows were last replaced. Of course, it is hard to simply take the seller's word for it, so it is worth asking to see the invoice or receipt for the replacement. Most people should have such proof, as it is needed to make use of the warranty. If the owner refuses to show the document, this may suggest that the windows were not replaced when they claim.

Condition of the glass

Even if we find out when the windows were replaced, we should still inspect them carefully. First of all, let us look closely at the panes. Let us check that they are not scratched or cracked anywhere.

Window sashes

Next, let us open each of the window sashes. Let us try every possible way of opening, including the tilt position. Let us check that opening and closing is smooth and easy, and that nothing sticks.

Window seals

The next step is to check the condition of the seals. First of all, let us see whether they are there at all, where they should be. The seals must not be worn, cracked, missing in places or mouldy. Any damage to them will mean they cannot do their job of insulating.

Window frames

We should also pay attention to the shape of the window frames. They must not be warped. We check this with a spirit level. The degree of deviation should not exceed 3 millimetres. If it is greater, the windows need to be replaced. It is also worth checking the frames for discolouration, cracks, scratches or dulling.

Damp stains under the window sills

The last thing to check is the area of the wall under the window sill. If we notice any damp stains there, it is a clear sign that the windows are not properly sealed and will need to be replaced.

The condition of the windows needs to be checked particularly carefully in historic tenement buildings. If we want to buy a property in such a building, we need to be aware that replacing the windows requires approval from the conservator of monuments. Moreover, when replacing windows in a historic tenement building, we will have to follow the generally accepted pattern. We cannot choose a different model from the one used throughout the building.
