Patio Door Seal Replacement
Designed to protect against severe weather, this patio door has double-paned glass with argon gas between the panes for energy efficiency. It's also rot- corrosion- and weather-resistant for durability.

This patio door comes with a built-in locking mechanism for security. It also has an insect flap to stop bugs from entering the home.
Sealing the Frame
Frames for patio doors are available in different materials to suit your taste and requirements. Choose from PVC and hybrid (PVC covered with aluminum) frames for a durable energy-efficient choice, or fully aluminum frames for a modern style. Frames are available in a variety of colours and finishes to complement your home.
The frame is the principal structure that supports your new patio door. It is vital to the function and durability of your patio doors. The frame is designed to form a a tight seal between the jamb of your door and the frame which prevents drafts and water infiltration, and protecting stored items against moisture.
The frame must be maintained and sealed to prevent damage, improve the insulation and maintain an even closing and opening. Caulk can be used to fill in any gaps and maintain the frame of your patio door. This is a straightforward DIY project that can be completed without the assistance of a professional.
Remove any weatherstripping that is a bit old around the doorframe. Be sure to wash the area thoroughly afterward and ensure that any remaining adhesive is removed. When the surface is free of any obstructions, carefully take measurements of the length and width of your doorframe to determine the proper size of replacement weatherstripping. The measurements must be recorded accurately as an incorrect dimension may result in the seal being improperly properly installed.
Begin by placing the new weatherstrip on the top jamb of your door frame. Press it down until it forms an enveloping seal over the frame. Then, work your way along each side, smoothing any rough edges or areas that aren't flush.
After the bottom of the jamb is covered, you can proceed with the rest of your installation. Examine the new weatherstripping on a regular basis to ensure that it's still in good working order and operating effectively, and if necessary apply caulk again as needed. This is an easy, quick job that takes about an hour to complete, depending on the condition of your patio door's weatherstripping.
Sealing the Jamb
The jamb for the door is the vertical frame into which doors are closed and provides structural support. It also seals gaps between the sill pan and frame against air infiltration and moisture.
Most patio doors are hinged and not sliding, which means there's a metal strike plate on the bottom of the door jamb, which will latch to the door sash when closed. The door pull lock hardware -- the knob and deadbolt -- sits in a grove or a hole in the strike plate.
To replace the factory jamb, header, and track leaf weatherstripping, first tilt your door open and then lift it off the tracks (get assistance if it's heavy). Then, use a crowbar to pry up the remaining bits of weather stripping. After my explanation , clean the jamb's surface and the sill pan using a damp cloth or a mild cleaning solution like rubbing alcohol to eliminate any remaining adhesive residue.
A wide range of jamb, track leaf and header weatherstripping is available, so finding the right replacement for your current installation isn't difficult. You'll need a product thick enough to stop the water from escaping, but flexible enough to accommodate a variety of frame depths and openings.
Tubular rubber or vinyl is a good option for small gaps, however, if you want something more durable, foam is the best option. If you have gaps larger than 6 inches, you should use an extra thick polyethylene product like EPDM.
Once you've identified the type of weatherstripping you'll need, gather the following supplies to install your new product:
650 WB Liquid Adhesive or ClearBond Liquid Adhesive
If you use these products correctly, they will create a secure weather barrier that stops drafts and also protects against water leaks. Make sure you choose the right product for your climate zone, and the type of frame. Clean the opening with bristles made of wire and rub with ethanol prior to applying the flashing. This will ensure that the substrate is free of dust, smooth and dry. When the sill and jamb are clear, cut a length of Aluma Flash(tm) flashing to size using an utility knife.
Sealing the Bottom Threshold
If you have a doorway that has an exterior threshold, it is crucial to seal the gap beneath it to stop cold and freezing air from entering your home. Sealing the threshold will not only reduce drafts but will also protect your flooring from moisture damage and insects. This is a simple task that can be accomplished in a matter of hours.
Before beginning the process of sealing your threshold, you will be required to clean the area and make sure that it is clean of dirt or debris. You will then need to ensure that the weather is dry and clean for your work. Masking tape can be used to protect the threshold while working.
There are a variety of ways to seal the bottom threshold of your patio door depending on its style and material. For instance, if your threshold is constructed of uPVC, you will want to use caulking that is compatible with the material, like DOWSIL Neutral Silicone. If your threshold is constructed of wood, on the other hand it is necessary to select a caulking product that is compatible with this material, too.
The most important thing is to ensure that you get the seal correct, regardless of what method you decide to employ. You will need to be precise and make sure that the caulking does not get too thin or thick. Also, be sure not to caulk the railing, as it could interfere with the door's capability.
You can use expanding foam to fill in the gaps if your threshold gap is greater than caulking's capacity. It will expand slightly when it cures which will create an elongated seal. However, it is crucial to follow the instructions for the specific kind of expanding foam you're using. Certain types of foam can be dangerous when not used correctly, so be sure to read the manufacturer's guidelines carefully.
Sealing the Glass
If your patio door is made of double-paned tempered glass, it's likely to have a rubbery seal around the edge. The glazing boot is what creates a tight seal between glass and metal frame. If your glazing boot is worn or leaking it could require replacement.
Many patio doors are outfitted with Low-E Glass. The glass is microscopically thin coating that helps reduce the amount of ultraviolet and infrared radiation that is absorbed by your home. The Low-E glass can help keep your home cooler during the summer and warmer in the winter, which saves energy.
If your patio doors are fitted with Low-E glass, then the window insulation kit that you can purchase at your local hardware store will aid in improving the performance of your doors. It's easy to install the new insulation kit. It takes only just a few minutes. You can even use one of these kits for a garage door.
