Contrary to popular belief, caulking is not the product used but the caulking action that means “hermetically sealing slots, joints (doors, windows, etc.) to prevent air and water ‘infiltrate (in your building) with a suitable sealant’.

The normal lifespan of a good sealer varies depending on its exposure to the sun and the wide variation of temperature like we have in Quebec. It usually can last up to 10 to 15 years. As a result, along with the other components of your building (roof, siding, etc.), the sealant should be checked regularly to avoid any trouble or significant structural problems that could occur in the short, medium and long term.

Therefore, caulking should be considered as an investment. While making sure that all seals are plugged properly, you extend the life of your building (s) and you improve your comfort and your quality of life.

Problems arising from a used and/or expired sealer

Water infiltration could significantly damage your building up to the deterioration of the interior and exterior materials. Obviously, if these infiltration problems are not addressed in the shortest amount of time, constant humidity, among other things, could create mold and funguses in the structure of your building(s) that are very harmful for your health.

Although it is less damaging than water infiltration, air infiltration can increase your heating costs significantly in the medium and long term.

Since apparent problems occur well after the start of an infiltration, an inspection of your caulking joints will prevent you from dealing with more expensive structural problems.

When should you check the sealant?

It is important to check the status of your sealer at least twice a year, in the spring and in the fall. It is also particularly important if it has not been replaced for more than over eight years or when you start to have complications relating to infiltrations problems infiltrations mentioned above.

What should you check?

  • Door frames and window joints
  • Coating of aluminum and/or wood and/or metal
  • Solin joints1
  • Dilatation joints2
  • Thermos window joints

1 Cover, device for sealing two edges that are exposed to the weather.

2 Cut in a building, to absorb the variations of thermal origin.


  • Removing of the existing sealant
  • Cleaning of the walls that needs to be caulked (if necessary)
  • Installation of an ethafoam roll3 (if necessary)
  • Apply sealant

3 An ethafoam roll is a closed-cell rod and we use it when the space between the two walls to be caulked is too wide and there is a risk that the sealant will collapse during the application.

It is possible that other steps, such as the laying of a primer or grinding of mortar joints are necessary depending on the nature of the work to be done. Essentially, the methods mentioned above are the ones mainly used in all our caulking jobs.

When using equipment such as a basket or a mobile scaffold, we make sure to use these equipment in a secure and safe way by following the standards of the CNESST (CSST).

Unless otherwise stated, our price includes labor, equipment, materials and a warranty of five years.
