Resistant paint

Our application process makes the paint very resistant to chipping, cracking and peeling. Our own paint room also allows us to apply an unlimited choice of colors in a controlled environment.

Energy losses caused by poorly maintained windows and doors reduce the efficiency of your heating or cooling system, especially in winter. It is therefore essential to replace them as soon as possible if you observe the slightest anomaly, especially if you are in an area such as the North Shore.

Good insulation ensures the optimal performance of your heating system

Good insulation protects your home from the elements. In other words, it limits the impact of the outside temperature on the comfort level inside. This reduces the use of the heating system and optimizes its performance. In addition to providing you with pleasant living conditions in your home, good insulation considerably reduces your energy consumption, and therefore your expenses, over the long term.

Doors and windows in good condition are essential for optimal insulation

When closed, doors and windows should prevent airflow between the indoor and outdoor environments. However, they cannot perform this function if they are in poor condition, i.e. if they have cracks or if they are poorly installed.

The weather will then have a significant impact on the indoor temperature, which could reduce the performance and efficiency of the heating devices. Thus, the condition and quality of the doors and windows play an important role in the insulation of your home. They should be replaced as soon as they show signs of wear or damage.

Keep the heat in during winter

And leave the heat and humidity outside during the summer

Our doors and windows are ecological and ultra-efficient for the Quebec climate. They make all the difference to your comfort.
