Add Or Replace Weather Stripping To Insulate Sliding Doors For Winter

Weather stripping creates a seal to keep bugs out and the air inside the home. The idea is for the air to not escape. You can add this stripping to single and double-paned windows as well as sliding glass doors. Weather stripping wears out over time so eventually, it will need replacing.

To determine if you need weather stripping or replacement, close your windows or doors to the outside. When you look in the cracks of the door, you should not be able to see sunlight coming in through the seal. If you can, you need to replace the . 

Weather stripping doesn’t have problems with moisture and will keep the drafts out. In fact, you can install this yourself or have a professional do it for you.

Tuning Up A Balky Door For Sliding Glass Door Repair: Adjust Rollers

To start your sliding glass door adjustment project, first lift or lower the door on the track with a screwdriver or Allen wrench. Raise it just enough to clear the track and roll smoothly. Locate the two adjusting screws at the bottom of the door and pry off the trim caps that cover the screws. If one side looks lower, raise it until the door looks even on the track . If the door still sticks, turn both screws a quarter turn to raise the whole door. Then slide the door just short of the jamb and be sure the gap is even.

Replacement Rollers: How To Replace Sliding Glass Door Rollers

New rollers for repairing sliding doors are available through door manufacturers or online suppliers, even for older doors.

Years of dirt, exposure to the elements and hard use can turn sliding doors into sticking doors. Here’s how to repair your sliding door and make it run like new. Sliding glass door repair will get the job done.

Stay Warm This Winter By Insulating Your Sliding Glass Doors

How to Winterize a Sliding Patio Door

If you feel like your heat runs around the clock as soon as winter arrives, yet it never seems to make much of a difference in certain areas of your home, your sliding glass patio door might be to blame.

Sliding glass doors, as attractive and functional as they may be, are often a major source of heat loss in our homes when they are not sufficiently insulated. Non-insulated sliding doors can create large drafts, causing the interior of your home to become downright cold. This is especially true for older doors, doors without double-pane glass, and doors with compromised weathering stripping or caulking.

If you feel a draft when you are standing near your slider door, there are several things you can do to solve the problem. The following tips and tricks for insulating sliding glass doors for cooler weather can help make your home more energy efficient this winter.

How To Seal A Sliding Glass Door From The Inside For Winter

Sliding glass doors can be a major chink in your house’s energy armor. During winter months, cold air radiates through the thin glass and cools the house, causing the furnace to work longer. Installing insulation over the stationary glass panel, and weatherstripping between the insulation and the sliding glass door effectively seals the sliding glass door from the inside. This insulation seal stops cold outside air from radiating into the house.


Close the sliding glass door and lock it.


Locate the flat door frame that runs around the outside perimeter of the sliding glass door.


Make pencil marks on the flat door frame, at the top and bottom edge of the sliding glass door panel, where the back of the door — the side opposite the door handle — rests when the door is closed.


Measure the opening from the outside edges of the flat door frame, from top to bottom, and from the side of the stationary glass panel to the marks you made on the flat frame.


Cut out the insulation panel with a long razor-blade cutter to the measurements you made.


Apply two coats of latex paint — in a color that matches the walls — to both sides of the insulation panel. Allow the paint to dry between coats.



Glue foam weatherstripping, using contact cement, onto the inside edge of the insulation panel to cover the gap between the sliding glass door and the panel.

Step #5: Install Any Weather Stripping That May Be Needed

Most sliding glass doors are installed with weather stripping already in place.

If you look between the two glass panels, you’ll likely see brush fin or fin seal weather stripping in place.

If not, then you’ll want to install this after you’ve finished with the insulation panel.

Peel the backing off of the weather stripping where indicated and then install on the frame of the door and not the glass.

Glass collects condensation that will eventually cause the weather stripping to fall off. Continue until the gap between the doors has been completely filled.

Step 1: Clean The Tracks And Edges Of Sliding Patio Door

Unlike a threshold like a traditional door, sliding doors have tracks. And tracks collect dirt and grime like a squirrel collects nuts. Even in the summer, you should make cleaning your tracks part of your routine. 

When tracks go untended, pebbles and dust can prevent the door from creating an airtight seal. As a result, you get air leaks. 

Here’s how you fix it. 

First, take your vacuum and attach it with a narrow hose fitting. Then, go around the edges and tracks of your sliding door and clean as much dirt as possible. Gently open and close your door several times to help stir up latent grime, then proceed to vacuum it up again. Do this until there is nothing else to vacuum. 

Then, take your cleaning solution and spray the tracks and edges. Use your cleaning brush and sponge to sop up the filth. Do this until the track sparkle. Be sure to dry any moisture. 

Note: don’t just clean the track under the sliding door, also clean the track the door slides into when you open it. If one side is dirty, it will pull grime to the other. 

Step Five: Install Insulated Drapes Or Window Treatments

There are many different types of products on the market to help with drafts that go through sliding doors. Once again, glass is not a good insulator on its own so investing in something like insulated drapes, cellular blinds, or blackout curtains can help with cold air exposure.

It will set you back some money yet the difference may get offset by a lower energy and heating bill. Plus, you’re just going to feel more comfortable when standing or sitting near the sliding door since many homeowners like to have their kitchen table close to a patio door.

If you live in a place that gets really cold in the winters, you’re probably going to spend a lot more time indoors than outdoors until spring finally starts. A large part of keeping your home warm and cozy during the winter months has to do with how well you winterize it. While a lot of people remember to take care to insulate their windows and doors, they forget all about the patio door. Here are some easy and effective tips on how to winterize a patio door.

Sliding patio doors are a great addition to any home. Even when treated for winter, these sliding glass doors are a great source of natural light. However, like all other entry and exit points in your home, they can let in drafts and let out much-needed warmth during the cold winter months unless they are insulated the right way. 

The problem is that glass is not a great natural insulator, which means that it isn’t particularly efficient in trapping heat or keeping the cold out. This is what makes winterizing so important. If poorly insulated, your patio door will not only make winter a lot colder for you, you will see a drastic increase in your utility bills. 

On the positive side of things, winterizing sliding patio doors is neither difficult nor expensive. Let’s walk you through the process.

Install Heavy Curtains To Seal Your Sliding Patio Door

One of the best ways to winterize your sliding patio door is installing drapes for better insulation. You can find cheap drapes or you can sew your own if you want to go frugal.

Next, you can choose to install thermal curtains. These can increase the value of your patio door. And you can even get them from a second-hand store.

If you’re not using your patio door that much you can just hang a thick wool blanket it to cover it. This should do the trick.

Weatherproof Your Sliding Patio Door For A Tight Seal

Use a weather strip to weatherproof your glass door. This can deal a deadly blow against the wind draft. However, weather strips are the best first line of defense against the cold weather as well as the debris from outside. Not to mention, they help keep the heat inside.

As a last resort, you can install a thick plastic sheet around the door. You might need to use a cutter and a hair dryer to fit it around the door. A little effort but the pay off is worth it.

Step Four: Install Panels Of Rigid Foam Insulation

How to winterize a sliding patio door

In worst case scenarios frost can develop on the inside of a poorly-insulated glass door. The remedy? Panels of rigid foam insulation. A panel of rigid foam insulation is really lightweight and easy to install. Homeowners have the option of covering the entire window with it or just the part that does not open.

The panel usually begins on the floor of the patio door and then extends above the top of the door frame.

Step #2: Measure Your Door For Size Not The Glass

You will be installing an insulation panel over the glass on your sliding door.

In order to properly install it, you’ll need the measurements of your door frame and panels. Many folks just measure the areas of glass and this creates problems with the installation.

If you need to make marks on your door to keep track of measurements, then make sure you use a pencil.

Measure from the outside edges of the flat door and the sides of the stationary panel in addition to the height measurements.

Five Ways To Winterize A Sliding Glass Patio Door

  • Keep the door Track clean and free of debris.The simplest and easiest way to keep your sliding glass door from leaking is by keeping the track and rollers clean. Dirt, gravel or other debris may prevent the door from sliding and sealing optimally.
  • Replace existing curtains with insulating thermal curtains.Thermal-lined curtains are thick, insulated curtains that block drafts and help prevent the loss of heat through windows and doors. Learn more about thermal curtains on last week’s blog post.
  • Install plastic window film.Specially designed plastic window film is an inexpensive, temporary solution that can help to insulate single pane glass doors during the coldest months of the year. Designed for windows, plastic window film is manufactured to be cut to size and can be tailored to fit any glass surface. Learn more about plastic window film, here.
  • Caulk the exterior of the door.Exterior caulk can deteriorate over time. Increase the efficiency of your frame by removing any damaged caulk and carefully replacing it. Choose a high-quality window caulking rope and caulk gel to ensure your work lasts for years to come.
  • Step 7: Dont Forget Other Parts Of Sliding Window

    Remember that glass itself is not the best insulator. Usually, a sliding door has at least two panes – many have three. Even after you’ve sealed around the door, make sure to take a moment and assess the other parts of the window. 

    You may want to great a foam board insulation piece to cover every section of the window. You don’t need to keep these in all the time, but it’s nice to have them on the cold nights. 

    Remember what we said initially – even if you can’t perform all these steps, at least doing some of them will drastically increase your ability to keep warm air in and cold air out. 

    Winterizing A Sliding Patio Door: A Helpful Guide

    Winter is the time of the year where most congregate inside and abandon the elements until the much-welcomed sun and warmer temperatures return in the spring.

    In order to keep you warm and comfortable during the winter, it’s extremely important that you invest some time and energy into winterizing your home.

    A sliding patio door often gets overlooked during this winterization phase yet is very important. Sliding doors can release a lot of controlled temperature from inside the home, as well as produce unwanted drafts from the exterior.

    Thankfully, it isn’t hard or expensive to winterize a sliding patio door. Here are the steps to making it a part of the solution, and not a problem, come time for colder temperatures.

    What Do You Do With Patio Furniture In The Winter

    If you have enough storage space, it’s always best if you can move the furniture to an indoor area. This will be your best defense and keeping it protected.

    Wrought iron, wood, and glass can all get damaged from the harsh elements from outdoors. Wicker furniture should always be stored in another place away from the elements. It will damage very quickly, so it’s not a good idea to leave it where water can get to it. 

    I highly recommend finding a storage solution if you splurged on high-end furniture. Sometimes placing furniture indoors isn’t an option. Wrap it tightly with a tarp or cover. Periodically, throughout the winter, take a broom and sweep off fresh snow. This will prevent it from all melting right on the furniture.

    If your furniture is wood and you opt to cover it with a tarp, seal it well before you do so. This will help protect the wood from mold and other damage.

    Can You Leave A Glass Patio Table Out In Winter

    Some people will brave it and leave their glass furniture on the patio in the winter, but it’s not the best idea. If you get a lot of snow or ice, you will find that the glass can be broken. It’s better to remove the glass pieces from the patio, wrap them in moving blankets and store them in a garage or shed for the winter months. The last thing you want to do is going out and find a broken table when it’s already cold. Cleaning up is going to be a pain and difficult, which could then cause you or others to get cut from missed pieces of glass.

    To create your insulator, measure the space you’d like to place the foam. Then, try to cut the foam board as exactly as possible. A snug fit will ensure the best protection from the cold weather. If you only want to use this on extremely cold days, you can take it out on warmer days and store it when the sun is shining.

    Insulate The Glass In Your Patio Sliding Door

    If your sliding door has a single pane of glass, it will not hold the heat in your home very well. Instead, it will act as a heat sink and suck the warmth from your home, transmitting it to the cold outside air. If your winters do not get cold enough to warrant double pane glass, the solution may insulate the single pane.

    The best way to insulate the patio door is with a kit that you can buy from your local hardware store. The kit will consist of a plastic film that you apply to the inside of your glass sliding door. The plastic coating is clear, so it will not restrict the view through the glass of the sliding door.

    The plastic film acts as a barrier between the glass and the air inside your home. It prevents the glass from transferring the heat from inside the room to the cold exterior.

    It is also important to remember that winterizing your sliding patio door will not only be a benefit in the winter months. An adequately winterized sliding door will also have benefits in the summertime. The insulation will keep your home cooler in the summer using the same principles that keep it warm in winter.

    Caulking To Insulate Sliding Doors For Winter

    Caulk does deteriorate over time so check the caulking around the frames and where the doors meet the house. The caulk should be in good shape and if it is not, then you will need to replace it. Hiring a professional is always an option if you need help.

    Rope caulk is a temporary fix and is great for the winter weather. In addition, it is easily removable in the spring and warmer months.

    Benefits Of Winterizing A Sliding Patio Door

    Sliding doors are a beautiful addition to any home, even in the winter where they provide much-needed sunlight during bleak, shortened daylight hours. They also are a prime culprit of producing air leaks and temperature loss.

    As a result, if you really want to maximize on your heating bill — not to mention feel more comfortable in your home during the winter months — you need to winterize a sliding patio door.

    Glass isn’t a good natural insulator when it comes to trapping heat or preventing outside elements from going through it. When left untreated, it makes your house less energy-efficient and adds to rising utility costs.

    It’s also uncomfortable if the sliding door is by a kitchen or dining table, as often is the case.

    Step One: Remove Debris From A Sliding Door

    Sliding Andersen® Patio Doors from Renewal by Andersen® of ...

    Patio doors are exterior units that often collect a ton of outside debris. Since they’re large they tend to act like a magnet for the wind that sweeps dirt, pebbles, mulch, leaves, and just about any other outdoor substance, you can dream up to the tracking.

    It’s amazing to discover exactly how much debris can collect on or near your patio sliding door, and in such a short time span.

    Consequently, one of the easiest ways to maintain a sliding door year-round is to frequently clean and remove debris from the patio door. What can take 5 to 10 minutes to sweep blow off with a motorized piece of machinery can save a lot of time come winterization.

    When dirt, gravel, small stones and other debris collects on the tracks of a sliding door it will not shut properly and also allow subtle, yet noticeable drafts of air to enter as well as escape. If the patio door is not in place, cold air and wind will easily enter your home.

    Before winter sets in a sweep or vacuum the tracking and clear any unwanted debris from just outside the entrance. You may need to repeat this process a few times throughout the winter after storms ravage a backyard. It depends on how much you enter or exit the sliding door during the winter months.
