So without further ado, let’s get started.

How to seal door gaps

When we want to have a well-sealed door, it requires two components: weatherstripping and a sweep. While weatherstripping covers the top and sides, a sweep fills the space between the door bottom and the threshold. You can use an array of plastic products, foam, metal, and felt for this purpose.

However, a planned approach will help you solve this problem effectively. Here are the steps that will help get a weatherstripped door.

Step 1: Door gap measurement

Measurements are vital in getting a practical solution, and you should measure the door gaps before ordering weatherstripping. Measure the head jamb and side jambs and pick your weatherstripping according to the requirements. Additionally, you can use a stepladder to get accurate measurements.

Step 2: Clear The Surface

Clearing out the surface from protruding nails and flattening it is a vital step of installing weatherstripping. You can use a flat pry bar, paint scraper, and a screwdriver for this purpose.

Step 3: Insert the weatherstripping

After you cleaned the surface, you can begin the installation process by carefully placing the weatherstrip. Secure the weatherstrip by pushing its barbed tongue from end to end until you get a satisfactory result. You can use a spline roller to finish the job and ensure that your door shuts without leaving any gaps.

Step 4: Rework the base

Weatherstripping is incomplete without reworking your door’s bottom. Although this task may require some expertise, you can get past it over time. According to experts, a 1⅛ inch depth should be enough to hold most weatherstrips. This equation will provide the best weatherstripping results for your door’s bottom.

Step 5: Attaching Channel

Attaching channels will ensure that your weatherstrip stays in place. Ensure that you place the channel at the center from end to end and use a driller to drill the holes. After placing the channels, use a screwdriver to screw them in place.

Step 6: Install The Door Sweep

After placing your channels, fit a door sweep and adjust the glides. Ensure that you hang your door first before installing them as they reduce possible damage to the sweep. Additionally, you can use plastic caps to seal the channel to provide additional strength.

Step 7: Adjusting The Glides

Adjusting the glides is a vital step in ensuring reliable weatherstripping. Glides allow sweeps to function at their best, and if you don’t make proper adjustments, your weatherstripping may fail. Here are the steps to adjust the fit:

  1. Open the door
  2. Remove the plastic cap (latch side)
  3. Slide-out the sweep
  4. Turn the glide clockwise to raise the sweep,
  5. To lower the sweep turn the glide counter-clockwise
  6. Once you have your desired results, slide the glides back
