5 Mistakes to Avoid when Installing Replacement Storm Windows 5 Mistakes to Avoid when Installing Replacement Storm Windows
Replacement storm windows are ideal for maintaining the temperature of the room inside. Particularly popular in colder climates, storm windows are perfect for when you want to replace your old windows, but can’t afford the cost. Moreover, are effective in reducing heating and cooling costs. Besides, if you are handy with tools, installing a storm window is less than half a day’s work. Also, if your house is an old structure, then storm windows are imperative because these can effectively prevent water from seeping into the structure of your home. Storm windows are also quite effective in stopping air infiltration into the room.
While installing a storm window may seem like an attractive option, there are a few mistakes that you must avoid when installing them. Here are five of the most common mistakes made when installing replacement storm windows.
1. Poor Fitting
Check the fit of the storm window. You have to be precise and thorough when you take measurements. If you don’t take at least three measurements of the width and height for each window, you can end up with a wrong fit. You will find that each time you measure there is a minimal change in the measurement. You then have to take the smallest of the three measurements. A common mistake is to measure the frame and get a storm window of the same measurement. Also, you should subtract at least ¼ of an inch from your measurements. This is because if the storm window fit is a tad smaller, you can always shim or caulk to fill the gaps; however, if the storm window is larger than the frame, it will be a considerable waste of time and money.
2. Avoid the Use Silicone
When attaching the fins of your storm window, use an elastomeric caulk, or even butyl; do not use silicone at any cost as it will complicate any future repairs and/or replacements of the window.
3. Proper Caulk Application
When applying caulk to the storm window, ensure that you apply it first to the side and then to the top of the window. It is best to take a little at a time and distribute it evenly as you move along; this is because lumpy or uneven caulk can affect the alignment of your window. Also, avoid applying caulk to the bottom of the window until after you've fitted and fastened the storm window.
4. Leaving Some Gaps
When fitting the storm window, you need to press it into the window opening, ensuring that it centers between the side stops of the window. It is common to fit the storm window in tightly between the casing and the windowsill; however, leave a small gap at the top. This is to allow the casing some space to expand when temperatures change.
5. Don’t Caulk the Ventilation Holes
Lastly, once the window is fastened, you will most likely apply caulk to the bottom edge of the window and fill up any gaps. However, you will notice that your storm window has a couple of small holes at the bottom. Ensure that you do not apply caulk and fill them, because they provide the much needed ventilation to avoid condensation.
