3 pros!
Do your rattling windows make you feel like you're living on the set of a scary movie?
If you live on a busy street or near an airport, there's a good chance that your windows have a distinct and unsettling rattling sound caused by cars driving by at high speeds or departing airplanes.
The rattling sound is caused by a vibration to the ground that transfers to windows which aren't properly secured to their frames. The same effect can occur during intense rain storms when extreme winds and heavy thunder are present.
The No. 1 reason windows rattle is because they aren't secure. The good news? We're going to tell you how to fix it.
Install weather stripping
Weather stripping can help stabilize the glass and seal air leaks around windows. For installation, you'll need a utility knife, measuring tape and several rolls of adhesive-backed weather stripping.
1. Using soap and water, thoroughly clean the area where you'll apply the weather stripping and wait for it to dry completely.
2. Use the measuring tape to measure each side of the window, and cut the stripping accordingly.
3. Raise the inner window sash and apply two pieces of weather stripping to this area.
4. Lower the outer sash and apply two pieces of weather stripping here as well.
Apply caulk around the window
Similarly to weather stripping, adding caulk around your windows will help stabilize the glass and seal any air leaks. To apply, you'll need caulk, a putty knife, vinegar and one clean rag.
1. Apply the caulk in the space between the frame of the window and the glass pane.
2. Using the putty knife, completely fill the crack by maneuvering the caulk into any empty spaces.
3. Fill a bucket with vinegar and soak the rag in it for a few minutes, then use it to wipe away any excess caulk from the window pane.
4. Once the caulk dries, double check for any exposed areas and refill these accordingly.
Permanently seal unused windows
If you have windows that you rarely or never open, it may be necessary to seal them completely to eliminate rattling all together.
1. To permanently seal the window, close the window securely and apply caulk to all four sides of the frame.
2. Install a single-pane storm window, and apply a bead of caulk over the area for maximum security.
Your final result will be airtight to the equivalent of a double-pane fixed window.
Although these solutions can be simple DIY projects, it's usually best to hire a professional window contractor to ensure the most effective application and to avoid any hazardous situations.
