Installing a Storm Door
Time Required: Over 1 day
Storm doors can be stylish and functional at the same time. Look for one that has a solid inner core, a low-maintenance finish and a seamless outer shell. Accurate door measurements are critical to ensure your new door fits. This guide will show you the steps involved in installing a storm door in front of an existing slab door.
Tools & Materials
Most doors are made so you can hang them with the hinges on either side using the same Z-bar. Put the Z-bar against the opening on the hinge side and mark the top with tape.
- Draw a cutoff line this distance from the underside of the top of the Z-bar.
- If the sill slants, follow the manufacturer’s directions.
- Cut along the line with a hack saw.
- With the exterior door closed, place the storm door in the opening and push the hinge side up against the jam.
- Make sure it is plumb and level.
- Open the storm door and add the remaining screws to secure the hinge-side Z-bar.
- Secure the top Z-bar with screws provided with a ¼-inch gap between the bar and the door.
- Check with a level to make sure it is plumb and check to make sure the door opens and closes freely.
- Make any necessary adjustments and add the remaining screws.
- Measure from the bottom of the rain cap to the top of the sill on the latch side of the door.
- Mark the measurement on the side Z-bar and cut with a hack saw.
- Make sure you adjust the cut to match the slope of the sill.
- Cut hinge-side Z-bar as in Step 3.
- Place it in the opening, tight against the rain cap. Adjust it so there’s a ¼-inch gap between the bar and the door’s edge.
- Screw it in place.
- Install the handle set and associated hardware.
- Slide the expander off the bottom of the door and install the sweep.
- Position the sweep so its weather stripping touches the sill and screw into place.
- Complete the installation by installing the door closer. Loosen or tighten as necessary.
