ᐅ Salamander window glazing seal is dirty (moldy)

Over the weekend, we noticed that the seal on the glass (outside) of some windows is very dirty, but to us, it looks more like mold.

The window installer is relying on the company’s statement (although we never signed or received this information).

Dirt between the glazing seal and the glass: The residues between the glazing seal and the glass do not constitute a defect. The following information applies: “Dry glazing is a standardized method for sealing the joint between the frame profile and the glass pane. This is referred to as a functional joint, which is not completely sealed due to external stresses such as wind pressure, driving rain, or heat exposure. To prevent water accumulation in the rebate area, drainage and pressure equalization openings are milled out. Incoming water can carry dirt particles that are filtered out in the sealing area and remain as dark deposits. These are mostly visible with light-colored seals (e.g., gray). This does not affect the functionality of the glazing system and therefore does not qualify as a warranty claim. This type of contamination does not constitute a defect.”

There are small droplets in the gap and also in the seal. One could try to lift the rubber and clean these areas, but the problem would return. The house is 1 year old and we haven’t even moved in yet.

I hope you can help us.

Could you please upload a photo? There is a lot of dust and dirt generated during construction. This area around the window can quickly look quite bad. It was the same for us. Apparently, heavy rainfall after the construction period mostly washes it away. The rest has to be cleaned manually. However, pollen will greet this spot every spring. The severity of this issue varies between manufacturers. Our windows tend to have this problem more than others. On other construction sites with significantly more expensive windows and different exterior seals, it is hardly noticeable.

Thank you for your response. This will not come off with washing, as it is stuck to the seal.

Oh, you have a light-colored sealant, which I haven’t seen before. In my opinion, the stains on your sealant look quite poor. With our windows, most of the stains actually washed out over time. It seems like your sealant itself has absorbed these stains. Have you tried cleaning it yet? You can also open the windows and remove the glass pane. Maybe you could ask the manufacturer to show you how to do this, then open the windows accordingly and clean all the seals. Do the stains come back after that?
