If you live in a home with windows, it’s important to ensure they’re installed correctly. Otherwise, you could be dealing with several issues that aren’t just an eyesore but also potentially dangerous. What sort of problems are we talking about? Poor installations can cause drafts, leaks and rot. We will explain each issue and what you should do if you discover any of these problems in your home.


If you’re not sure whether or not your windows are properly installed, here are some common problems that can indicate a lack of airtightness:

  • Drafts. Drafts are caused by air moving through gaps in the window and around the frame. This can cause your heating bills to go up as you have to use more energy to heat the drafty room. It’s also unpleasant for those living in a drafty house. The temperature difference between the inside of their homes and outside is like sticking their heads out an open window on a cold day—they’re going to feel it!
  • Condensation on windows. When there’s moisture in between panes of glass, it can create condensation on surfaces like window tracks, frames and even glass itself (which makes it difficult for people with allergies). The same thing happens when there isn’t enough insulation around openings such as doors or skylights because they aren’t sealed properly—which causes drafts too!


Leakage is a common problem with windows that may not be installed properly. A poorly installed window will allow water to enter your home and cause rot and mould. The rot and mould can spread to other parts of your home, including the window and frame.

Rotting or warping

If your windows are not properly installed, they can cause rot and warping. One of the main issues that cause this is if the window doesn’t fit correctly in its frame. This will allow water to seep through cracks and cause rotting of the wood or moulding around the window.

To avoid this problem, ensure that when replacing windows in your home, you ask your contractor if they will use a sealant around any outside openings for proper insulation.

To avoid these problems, check the quality of your window installations.

You can do that by inspecting for drafts and leaks, rotting or warping wood frames, and improper caulking around windows.

If you find any of these issues in your home, contact a professional contractor to make an appointment with them right away.

In conclusion, proper installation of windows can prevent problems in the future. If you want to ensure that your home is properly protected from drafts and leaks, consider hiring an experienced professional to install your windows.
