To avoid common mistakes when installing aluminum sliding windows, it’s important to follow best practices and take careful steps throughout the process. Here are key points to help you avoid typical errors:
1. Inaccurate Measurements
- Mistake: Not measuring the window opening correctly.
- Avoidance: Measure both the width and height of the window opening at multiple points (top, middle, and bottom for width; left, center, and right for height). This ensures you catch any irregularities. Subtract 1/4-inch from the smallest measurement to leave room for adjustments and insulation.
2. Installing Without a Level
- Mistake: Failing to check if the window is level and plumb (vertically aligned).
- Avoidance: Always use a level to check both horizontal and vertical alignment during installation. Uneven windows can cause poor functionality, leaks, and drafts. Adjust with shims to ensure the window sits squarely in the opening.
3. Improper Use of Shims
- Mistake: Overloading or underusing shims.
- Avoidance: Shims should be used sparingly and only where necessary to ensure the window is level and secure. Place shims on the bottom corners, sides, and top where needed, without overstuffing, which can distort the frame and impair operation.
4. Not Securing the Frame Correctly
- Mistake: Using incorrect screws or not securing the window frame tightly enough.
- Avoidance: Use the manufacturer-recommended screws, typically provided with the window. Make sure screws are tightly secured into the window frame without over-tightening, which can warp the aluminum frame. Insert screws at the designated points to ensure structural integrity.
5. Neglecting Sealing and Insulation
- Mistake: Not applying sealant properly or forgetting to insulate gaps.
- Avoidance: After the window is installed, apply a high-quality silicone sealant along the edges to create an airtight and waterproof seal. If there are gaps between the window frame and wall, use expanding foam or insulation to fill these gaps. This prevents drafts and moisture infiltration.
6. Overlooking Weatherproofing
- Mistake: Ignoring weatherproofing or flashing around the window opening.
- Avoidance: Install flashing or a moisture barrier around the window frame, especially if you live in a region with heavy rainfall. This step prevents water leaks that could lead to structural damage.
7. Poor Window Alignment Affecting Operation
- Mistake: Misaligning the window frame, causing the sliding mechanism to stick.
- Avoidance: Test the sliding window by opening and closing it a few times before permanently securing it. If it sticks or doesn’t slide smoothly, adjust the shims and realign the window frame to allow smooth operation.
8. Ignoring Manufacturer Guidelines
- Mistake: Skipping or disregarding the manufacturer’s installation instructions.
- Avoidance: Always follow the window manufacturer’s instructions, which often include specific steps unique to that product. Ignoring these can void warranties or lead to installation errors.
9. Rushing the Job
- Mistake: Trying to install the window too quickly, leading to mistakes.
- Avoidance: Take your time at each step, especially when leveling, securing, and sealing the window. Rushing through these processes can lead to operational issues or long-term problems like drafts and leaks.
10. Improper Disposal of Old Windows
- Mistake: Not properly removing or disposing of the old window, leading to debris that interferes with the new installation.
- Avoidance: Completely remove the old window and any remnants of caulk or debris before placing the new window. This ensures a clean and smooth surface for installation.
By paying close attention to detail and taking your time, you can avoid these common mistakes and achieve a successful aluminum sliding window installation that is both functional and long-lasting.
