Sealant replacement

Whether you are looking for a way to prevent mold and mildew problems, or a solution to repair an old seal that has weakened over the years, Les Entreprises JSDR inc. can help. Our weatherproofing techniques are efficient and adhere to the following steps:

Removing the old sealant

The first step is to completely remove the old sealant using a high-power multi-purpose tool. This ensures easy application for the new weatherstripping material and, in the end, a better seal.

Application of Ethafoam ™ rods

When joints are too wide to be filled only with sealant, this second step involves applying Ethafoam ™ rods to joints, creating a strong base for sealant adhesion.

Tidying the installation area

The third step involves cleaning all surfaces and applying a primer. This is to ensure that no dirt or dust will interfere with the adhesion of the new weatherstripping material.

Application of a new high-quality sealant

The fourth step involves applying new high-quality weatherstripping, according to the manufacturer's technical specifications, and to smooth the joints in order to obtain the best possible seal.

Contact Les Entreprises JSDR inc. to replace any old weatherstripping at your home or business, or on your industrial or commercial building.
