Calfeutrage Apex is a family owned business which specializes in caulking on the South Shore of Montreal. Our business offers caulking services to seal your property professionally with the best products on the market at competitive prices.

No matter the building, we can caulk it!

Caulking doors and windows protect your residence, your business or building from heat loss, moisture intrusion, mold rot, cold drafts or even from insects entering your structure all year round.


In collaboration with the managers and boards of directors of condominium buildings, we build a plan that is tailored financially, technically and professionally to the building’s co-owners and management. We meet the highest standards of the construction industry and always apply sealants according to a rigorous process that guarantees the quality and consistency of the work.


We are the gold standard in residential caulking services on the South Shore of Montreal. We can provide caulking joints on a new construction or replace old caulking on an existing residential building. Homeowners can ensure that their building envelope is watertight and avoid problems caused by water, air or insect infiltration.


Caulking joints are extremely important for commercial buildings, especially in terms of airtightness and visual appeal. When joints in a commercial building are damaged or simply poorly made, property damage, financial loss and even health risks to customers and employees can result. We can properly replace or install your caulking to ensure a job well done!

Say goodbye to inefficient and unsightly caulking

The wearing out of caulking around your structure can be a result of poor caulking material, bad application, pollution, UV exposure or temperature extremes.

We understand the devastating consequences of flawed caulking on your structure and we take every necessary step to ensure that our caulking applications are done precisely and accurately to last for many years with a 10-year warranty. We always remove old caulking before applying the new layer and we make sure that every crack is properly sealed.

What is caulking?

A caulking joint bonds together two materials, for example, a window frame to a concrete wall or between two concrete panels, in order to block the movement of water or air through the building envelope.

Professional caulking has to be performed to the highest standards and in accordance with the construction industry. The caulking sealant has to be applied on a clean surface; free of dirt, old material, moisture and dust.
