When to do the caulking again?

This is when the old sealant shows signs of cracking or premature detachment, as they allow air and water to seep into your building. Depending on the types of sealants used and the quantities originally applied, this will occur differently from one opening to another and randomly from one façade to another.

First weaknesses of joints as young as 5 or 6 years old

Most original sealants last about 15 years, but they begin to show signs of weakness such as micro-cracks as early as grade 5 or 6. Unfortunately, it is not uncommon to see detachments on almost half of the openings after only 9 or 10 years.

Why these weaknesses?

The small quantities applied originally are not very resistant to the effects of the Quebec climate and are under a great deal of stress during the drastic temperature changes we are experiencing. In addition to being as aesthetically pleasing as possible, sealing joints have as their main function to seal the perimeter of doors and windows.

The Elite Caulking Professional Solution

Here are the recommendations of your favorite caulking company on the North Shore For it to be the most efficient and durable, the seal must adhere to maximum surface area on either side of the frames and substrates.

The larger the grip surface, the longer the seals will remain watertight.

Unfortunately, caulking experts too often see joints that barely touch the edges of the frames and begin to peel off as soon as the materials have undergone the first effects of the season changes.

The wider the seal and adheres to the maximum surface area, the longer it will last.

Polyurethane and silicone sealants are of high quality and are among those that last a very long time. Applied according to industry standards and manufacturers’ recommendations, they can really last between 20 and 25 years. As our caulking expert mentions in our advice page,we only use this professional quality and our joints are really wide as the original joints.

Technical reminder of installation

• Brick,
