In April 2021, electricity rates in Quebec increased by 1.3%. In April 2022, these rates increased by 2.3% and experts predict an increase of up to 5% in April 2023. However, there is a way for homeowners to control their electricity costs, and that is to insulate their windows! With that in mind, what is the best window insulation available today?


When it comes to insulating the exterior windows of your home, several options are available to you. The problem is that few people have considered caulking their windows, and it’s unlikely that they know the benefits that window insulation for winter can provide.


The good news is that we have decided to break down exactly why the window insulation seal is so important.

So, if you want to learn how to insulate windows from the cold, and where to find caulking on Montreal’s South Shore, read on.

Why Is Caulking So Important?

Before we get into all the benefits that window insulation can offer, let’s first touch on why insulation is so important. It’s no surprise that almost every home has a place where cold air seeps in during the winter.

For many homes, this is due to a poorly insulated window, which increases energy costs, and it can be difficult to find the best solution to remedy this.

Window caulking is an effective way to seal any leaks where the air is escaping. It also offers a unique solution because few other insulating materials can claim to be as effective.

Why It’s More Effective Than Other Insulations

While there are other options for insulating windows, nothing is as effective as caulking. That’s because window caulking is made with a material specifically designed to prevent air gaps.

Caulking is easily accessible, so every homeowner can use it to repair a crack or gap in the window seal.

Window caulking can be applied to a wide range of building components, so it is not specific to windows alone. However, if it is not done properly, problems can occur. That’s why it’s important to hire an experienced professional.

The Benefits of Caulking over Insulation

The great thing about caulking is the fact that it has multiple benefits. We have covered some of the top benefits below.

It’s Inexpensive 

One of the main benefits of caulking is that it is inexpensive. This means that you don’t have to spend a lot of money to insulate windows for the winter.

Typically, insulating a home is a significant expense, especially if you need to insulate multiple locations. With caulking, however, you can seal several windows and door joints and insulate a door frame for a fraction of the cost of insulation.

It Saves You Money on Heating Costs

Another benefit of caulking is that it is not only inexpensive to purchase, but it can continue to save you money on operating costs. This is a huge benefit for any homeowner trying to save money on their energy bills.


What’s nice is that caulking won’t just save you money in the short term, but in the long term as well. So, you can be sure that you are getting value for your money.

It’s Durable

When thinking about how to insulate your windows in the winter, you want to make sure you find a solution that lasts. Caulking is very durable and can last a long time. So, you won’t have to worry about constantly replacing it.


Caulk is also able to maintain its structural integrity, which is why it can last so long. This makes it one of the best window insulations you can find.

Where to Get Insulation 

To caulk your doors and windows, you need to hire a caulking company. Many companies will offer you good deals on their services.

Choosing the Right Company

Unfortunately, some companies make promises they can’t keep, and their customers are then left to deal with faulty insulation.

However, in order to choose the right contractor to effectively insulate your windows and doors for the winter, we recommend looking for caulking companies that are known for their quality services. Start by reading reviews on Google and look for the company that has the highest score. Read what customers are saying about the company and look at pictures of the work they did. A good professional caulking contractor will show lots of pictures of their work.

Next, make sure the caulking contractor has a valid and current RBQ number, CENSST insurance for their crew, liability insurance and a valid CCQ certificate (multi-unit buildings), as well as a security card. By choosing a company that meets the requirements of the law, you can be sure that the work will be done in accordance with the building code and that you are choosing the best caulking solution for your building.

Use the best materials.


Choose a caulking company that uses the best sealants that can last 10 to 15 years. Beware of contractors who offer to use Flextra or other types of cheap sealants that barely last 2 to 4 years. DOW or ADSEAL sealants are flexible and durable products.


Work Method


Finally, ask about the work method. A professional contractor will remove the old sealant before applying a new one. When it comes to insulating your windows and doors, don’t settle for less. Protecting your investment from costly water damage is the top priority.
