MK Calfeutrage (Qc)

Founding President

Director of Operations

Mr. Sylvain Brassard has been an integral part of MK Calfeutrage's staff since it was founded in 2012. Over time, he has developed a relationship of trust with the company because of its integrity and transparency as a person. Thanks to his determination, he has managed to bring with him a wealth of experience and knowledge of more than 25 years. This eventually helped the company to achieve higher goals. For Mr. Brassard, everything began in 1982 when Marcel Leroux Caulking gave him the opportunity to work and become a professional shooter applicator. He stayed with the same company until 2012 for which he managed several major projects (Complete renovation of caulking at the Cité de la santé hospital in Laval in 2008, Courthouse in Drummondville in 2010, Hôpital Hôtel- God-Of-Sorel in 2012). Today, Mr. Brassard is a trusted leader and invaluable aid to further the development of MK Calfeutrage.

Properly done draft proofing eliminates harmful mold for the health of your family? It also settles air infiltration, water and insect problems.

Draft proofing prevents water infiltration, which can lead to mold problems and affect the building structure.

It is normal that the original caulking of doors and windows be replaced, as well as that of newer homes, since the original caulking is often of poor quality and do not offer optimal energy efficiency.

Did you know that certain insects and vermin can get into the building through your doors and windows, causing harmful damage to your building structure, resulting in major repair costs?

Did you know that draft proofing maximizes the value of your building?
